Paint shop with water curtain. Painting booths for furniture production Outdoor painting booths

P painting booths with a water curtain - this is perhaps the most advanced design option for painting systems. Equipment of this type is used for painting large-sized products, including car bodies, or individual body parts, various furniture structures, etc.

Any spray booth is based on the fact that air moves inside the system, which carries with it mist from the paint, which evenly settles on the surface to be painted. And if in a traditional paint booth there is a possibility that harmful substances or paint particles will come out of the chamber, then in chambers with a water curtain the paint particles are retained by water. Moreover, water molecules bind molecules of harmful volatile substances, which are found in excess inside the paint booth.

Thus, hitting harmful substances into the surrounding atmosphere is sharply reduced. But you can't say that water curtain provides a complete guarantee that the emission of harmful substances into the atmosphere is completely excluded.

In addition, there are chambers that operate in a partially closed air movement cycle. In this situation, it turns out that the air that has already been in the chamber enters it in the next cycle. And if it is not sufficiently cleaned before reuse, paint particles that have already begun to polymerize will enter the chamber along with the air. And this can significantly affect the final quality of the coating. And the water curtain, which can have different designs, traps paint residues.

How do water curtain spray booths work?

The principle of operation of a waterproof spray booth is very similar to traditional spray booths. Air is sucked from the atmosphere into confined space cameras. Air is sucked in due to the operation of the fan. The air enters through a system of filters, each of which provides a certain level of purification. The smaller the holes in the filter material, the finer the cleaning.

During the painting stage, the air heats up when passing through special heating elements. The temperature in the chamber begins to rise.

There are exit holes at the bottom of the spray booth. Moreover, they can be located in different places in the chamber (depending on the hole). Through these holes, due to the operation of suction fans, air leaves the confined space of the chamber. And it is in front of the main line, which works to remove air from the chamber, that water curtains are installed, which can also have a different design. Essentially, the air mixed with paint that comes out of the chamber passes through a thin wall of water. And all suspended particles remain in this water.

The water curtain can be considered as a water filter. Although there are options when the air does not pass through a wall of water, but through a special container with water. In this case, solid particles gradually accumulate at the bottom of the container, which then fall out as sediment to the bottom of the container.

In order to activate the process of binding harmful substances in the air with water, a special reagent is added to the container, which is a catalyst for chemical reaction cleaning.

The most advanced water curtain spray booths support multiple levels of air purification. The first level is when the air passes through the frontal water curtain. Flow water is coming a solid wall, and the speed of water movement is the same all the time. Water covers the entire surface of the front part of the curtain.

At the second level there is a more subtle air purification from paint particles. This is the so-called internal cleaning level. According to experts, it is at this stage that the most complete purification of the air from paint impurities occurs.

The finest cleaning occurs on final filters, which can be made on the basis of hydrocarbon technologies (carbon filters) or dry filters, which are made on a different basis. Here literally all remaining paint particles are removed. This protects the fan blades from paint residues sticking to them.

Painting booth with a water curtain»>An excellent business solution is to paint cars at home. But in order to be able to paint cars, there is little experience and equipment for painting, you also need to have a room in which the painting will be done vehicles. Organizations that paint cars have long carried out painting work in a chamber with a water curtain. It is no secret that such a device can be made with your own hands, only by making some efforts and spending a small amount of money to purchase some equipment. You can buy a ready-made one, but its cost will be very high, and not everyone is ready to invest a large amount. In order to make a device with a water curtain with your own hands, you will also need some knowledge.

A spray booth with a water curtain is a closed room made of stainless steel and has supply and exhaust ventilation. This ventilation is created using electric motors. The main part of the device is a heating element, which helps heat the room to the required temperature and maintain it during painting work. The chamber also includes lighting, which must be distributed evenly over the entire area and have sufficient luminous flux. It is best to place them not only on the ceiling of the room, but also on the side walls. The device also includes equipment for painting work and other auxiliary tools.

Layout of the painting booth

Knowing what the paint booth consists of, you need to decide on the location where the arrangement will be made, and make a project according to the location of the main structural elements. An excellent location for the construction of the device can be a garage, or build a new extension, which will take more time and, accordingly, finances. To make a device with your own hands, you will need structural elements from which it will be based, heating and ventilation systems, filtration and lighting.

Making a painting booth

Having made the layout, it is necessary to carry out all technical calculations and begin installation work.
First of all, a new room is built or a frame is assembled inside the garage. The overall dimensions should be: length 10 meters, width 8 meters, height 3.5 meters. The painting booth has the following dimensions: 4 meters wide and 6 meters long.

    1. Gate installation.
      It is best to use insulated gates to avoid suction and loss of warm air; the outside is lined with corrugated sheeting. At the point of contact between the gates, it is insulated with a special adhesive tape. Places with cracks must be foamed with foam.
    2. Floor construction. The base of the floor is made of concrete, inside which a hole is made, and a metal pipe with a diameter of 150 mm is led out onto the street for air outflow. A metal grate is placed on the floor over the entire surface of the room to a height of 15-20 cm.
    3. Walls. The walls are sheathed with corrugated sheets, and the inside is insulated; sandwich panels can be made.
    4. Air exchange system. Components: two electric motors and metal pipes with diameters of 100 mm and 150 mm respectively. For supply ventilation An electric motor with a power of 5 kW is used, for an exhaust motor at least 7 kW.
    5. Ceiling. It is made of corrugated board, with insulation. Ceiling mounted metal frame for air flow. An electric heater that will supply warm air indoors, installed outdoors.

  1. Air purification. It is carried out using filters and has three-level cleaning.
    • Level 1 A frontal water curtain is created, which is carried out by flowing down uniform streams of water;
    • Level 2. Cleaning the air inside the device. Promotes filtration and purification of air from paint waste;
    • Level 3. Dry filtration. Helps to completely clean the air from paint particles and protects the fan from paint sticking.
  2. Lighting. Mounted LED or fluorescent lamps along the ceiling and walls of the room.
    Also installed automatic sensors management and control of the system of supply and exhaust fans and filters.
    After installing everything necessary for the water chamber, painting equipment is installed.

How the work is carried out

An electric heater pumps air from the atmosphere into a confined space in a room. As the air passes through the system, it is purified by filters, each of which provides a specific purification.
The temperature in the room rises due to the work of the heating elements. The painting process begins. Down on the floor, air begins to be sucked out of the chamber, using exhaust fan. Water curtains are installed in front of the main line, which help retain paint particles. Here the air goes through all three levels of purification, if these are pre-installed. Cameras with a water curtain and factory production work on the same principle.

Positive aspects of a DIY device

  1. Free system planning.
  2. Big savings.
  3. Possibility to save on all components.
  4. Ability to use the main parts of the structure.

Disadvantages of the device

  1. There may be inaccuracies in calculations or imperfections in the installation of the device.
  2. It is not possible to completely automate the process, since the elements of the device consist of separate parts.
  3. There are no guarantees for the performance of such a device.

Price

The cost of constructing a water curtain chamber with your own hands can take a long time, but it will cost about $4,000. You can buy a factory one for $20,000 or more. To start a business, the best option There is a construction with your own hands, which is much more profitable for a start-up business.

The use of spray booths with a water curtain allows you to improve the quality of finishing and eliminate the influence of harmful substances on humans and the environment, which is determined by various factors related to the size of the products being painted, the volume and type of sprayed material, the duration of use of paint booths, and safety requirements environment, labor costs. For all cases, you can select the appropriate spray booth with a frontal suction system with water filtration, which ensures the sedimentation of solid particles. In this case, the product must be located between the operator and the active camera curtain. When choosing a stand, it is necessary to evaluate the size of the product being painted and the need to use a booth for the simultaneous work of several operators.

Spray booth with water curtain mod. W3000 is designed for:

  • significant improvement in the quality of paint and varnish coatings;
  • significant reduction in maintenance time for painting areas;
  • increasing the productivity of painting areas;
  • ensuring acceptable sanitary and hygienic working conditions for painters and support staff;
  • immediate removal of solvent vapors from the work area in order to prevent the formation of explosive concentrations;
  • significantly reducing emissions of paint and varnish sludge into the environment;
  • reducing the fire hazard of the paint job.

Applications

The W3000 water curtain spray booth is successfully used for painting metal, glass, wood, plastic and products made from them.

The range of painted products is very wide:

  • painting wheel rims
  • painting of large metal structures
  • painting of garden and agricultural equipment
  • painting drills
  • painting pipes and poles
  • painting piles
  • painting welded air ducts
  • painting formwork
  • painting elements of building structures
  • painting cement-fiber boards and other building and finishing materials

  • painting tables
  • painting chairs
  • window painting
  • painting doors
  • painting molded products (door moldings, skirting boards)
  • painting parquet and floor boards
  • painting of other furniture and joinery products

Operating principle

Some of the paint and varnish material sprayed by the painter does not fall on the product. At the same time, fine dust from the quick-drying components of the varnish is formed in the air - dust, which, thanks to the painting booth is removed from the working area by an air flow parallel to the floor.

A significant part of the varnish dust is deposited on the water curtain (up to 85%).

Additional filtration systems (optional) - a labyrinth of barrier panels that repeatedly change the direction of air flow, as well as quick-release cassettes with an inexpensive replaceable element - a fiberglass filter - allow achieving a degree of purification from solid particles of up to 99%.

A “side effect” of using water in the filtration system is the absorption of solvents when the chamber begins to operate. After the water is saturated with solvent molecules, the absorption of “odors” stops, and the illusion of their filtration disappears.

Basic equipment

    Prefabricated body and settling tank made of galvanized steel with a large number of longitudinal, transverse and vertical stiffeners.

    Provides durability and reduced vibration during operation.

    Double cascade of water curtains.

    The front curtains of both cascades (those through which water flows) have a quick-release design. Thanks to this, not only is full access to the interior of the chamber for maintenance possible, but it also makes it technically possible to narrow the gap between the lower edge of the curtain and the water in the bathtub located below. For the upper cascade, this is the bath of the lower cascade, and for the lower cascade, this is the settling bath.

    This design has a number of advantages, the main ones being:

    • due to the absence of long sections of free fall of water, the formation of splashes in both the upper and lower parts of the working area is eliminated;
    • water rushing off the lower edge of the water curtain creates a dense flow that additionally cleans the air of suspended particles, which eliminates the need to install water sprinklers;
    • the speed of air flow after entering the painting booth is reduced by 4-5 times, which allows suspensions to settle into the settling bath, increasing the degree of purification of the emitted air.

  1. Attached bath to accommodate the pump>

    The location of the bath is universal (to the left or to the right of the camera). In this way, the service side can be selected during installation.

    The location of the service area outside the chamber allows for visual control of operation and avoids external contamination of the pump, which leads to its overheating and premature failure.

    Valves located outside make it easy to regulate the water flow in the water curtains, as well as to quickly drain water from the chamber using a standard pump during its scheduled maintenance.

    A stainless steel pump that pumps lumps of coating sludge with a diameter of up to 35 mm, as well as a built-in overheating protection system.

  2. A system of circulation water lines, including a water circulation valve, an automatic water drain valve, all necessary hoses, passage units, flanges, clamps and other installation materials
  3. Mounting kit including bolts, nuts, washers, sealant, etc. according to camera configuration
  4. Packaging for transportation by road
  5. Passport and instruction manual
  6. CD with diagram and photo illustrations of the assembly

Additional options

    Explosion-proof exhaust fan.

    Explosion-proof design, with an explosion-proof motor (optional - with a general industrial motor or not explosion-proof).

    1a- Fan with a wafer-type supporting body. Thanks to the installation of additional amplifiers through a rubber gasket directly on the roof of the chamber and the placement of additional amplifiers in the fan installation area, vibration resulting from clogging of the fan blades during intensive operation of the spray booth is minimized.

    The fan motor together with the impeller is completely removed from the housing. To do this, you do not need to caulk the air ducts or disconnect the electric motor from electrical network etc. This fan design minimizes maintenance time.

    1b- Fan with supporting frame. The fan can be installed in any convenient location, incl. outdoors, and is connected to the chamber by an air duct (the air duct is excluded from the supply).

    The design provides the ability to remove the motor together with the impeller from the fan housing without caulking the air ducts. This ensures ease of maintenance and minimizes technological downtime of the painting chamber.

    Additional air filtration devices

    The combined use of devices allows achieving a degree of solid particle removal of up to 99%.

    2a- A labyrinth of barrier panels that repeatedly change the direction of air flow. At the same time they are additional diagonal stiffeners. Recommended for installation when placing the fan on the roof of the chamber.

    2b- Quick-release filter cassettes with an inexpensive replaceable element - a fiberglass filter.

    Electrical control panel

    3a- Shield in a plastic case with automatic switches– for placement outside the hazardous area

    3b- Shield in a metal case with on/off/emergency shutdown buttons – for placement outside the hazardous area.

    Explosion-proof fluorescent two-lamp lamp, 2x36W. The lamp is supplied with 2 lamps.

    Increasing the depth of the working area by 500 mm

    Set of two side panels and a roof panel.

    Water floor

    The water floor bath is integral with the settling bath of the paint booth and has a height of 300 mm from the workshop floor level. Thus, no gangways are required, making it easier for the operator to move around. The large volume of water filling the bath makes it possible to increase the interval for cleaning paint and varnish materials from accumulated sludge, reducing process downtime. Galvanized gratings covering the water floor can withstand a footprint load of at least 200 kg and 450 kg/m2.

  1. The supply fan and set of filters for the “economy project” include:

    • Supply fan of general industrial design. To create excess pressure in the paint sprayer, the capacity of the supply fan is selected to be 10-20% greater than the exhaust fan, taking into account the fact that the resistance of both the pocket filter and the filter of the air distribution device must additionally be overcome.
    • A pocket filter in its own housing, designed for connection with the supply fan. The filter design is quick-release. The filter is designed for repeated use. Its regeneration is carried out manually, mechanical cleaning and purging.
    • A roll of fine filter (20x2 meters) for the buyer to independently sew an air distribution hose.

Let's figure out what types of chambers there are for painting furniture parts. Depending on how many and what sizes the parts will be painted, what paint and varnish materials you will use, the required one is selected spray booth.

Spray booth with dry filters

Due to its design, when painting in a dry spray booth, excess paint mist and contaminated air are removed from the paint application area, while cleaning it. All this works when correct selection fan

What happens when using a spray booth with dry filters?

When operating a dry spray booth, the following processes occur:

  • removing paint particles and dust from the spray area
  • removal of paint aerosol, while preventing its spread into adjacent rooms
  • conditions are provided for receiving paint coating high quality
  • the air that is removed from the painting area is cleared of mechanical paint particles that remain in the filters and released into the atmosphere.

How is air filtered in a dry spray booth?

The air flow, which is contaminated with paint and varnish products, with the help of a fan moves by inertia into the opening of the chamber where it is installed one or two filters.

What types of filters are there for a dry spray booth?

Filters for dry spray booths are:

Cardboard filter

The principle of operation of a cardboard filter is as follows: particles of paint and varnish hit the inner wall of the filter several times and settle there, and the air continues to move by inertia, with no loss of air speed during suction.

An example of calculating the filtering capacity of a dry filter

For example, you have a dry spray booth 2 meters long with a suction area of ​​3.6 sq.m. This area corresponds to two pieces of cardboard filter 0.9 meters high and 2 meters wide.

The filter holds about 15 kg of paint per 1 sq.m. It turns out that the filter of our spray booth will hold 54 kg of paint waste. To calculate, we simply multiply the holding capacity of the filter by its area: 15 kg/sq.m.*3.6 sq.m. = 54 kg.

Glass fiber filter

The fiberglass filter is made of fluffy interwoven glass fiber that is impregnated with a special compound. The filter retains paint mist particles.

The fiberglass filter can be used as the only or second level of air purification from paint mist.

In the version of the second level of filtration, this filter is installed behind the cardboard filter. Often, a fiberglass filter in a roll is installed on the floor of car cells, hence its second name – “floor”.

The service life of such filters is short, only 60 hours of coloring.

How long does a dry spray booth filter last?

This question, undoubtedly, in addition to the technological part, also has an economic component.

The basis for calculating the “lifetime” of a dry filter is the following components:

  • how many kilograms of paints and varnishes do you spray per day?
  • what kind of paint guns you use, that is, what losses of paint materials occur due to fogging
  • what products are painted
  • how they monitor the cleaning of spray booths and replacement of filters.

Example of calculating the lifetime of a dry filter

For example, you again have a 2-meter dry painting booth, paint consumption per shift is 20 liters per day (excluding solvent), you use a paint sprayer with a traditional spray system, the material transfer coefficient is 40-45%, that is, 8 liters out of 20 liters of paint flies into the fog.

Ours showed that it can hold up to 54kg of paint. It turns out that one filter replacement will last 54/8 = 6.8 days, that is, about a week of work. And if you bought a roll of filter, then it will last for a month, you can figure out how much money it will be for yourself.

Spray booth with water curtain

A spray booth with a water curtain ensures maximum cleanliness and dust removal in the painting area. All this allows you to create ideal conditions for obtaining a high-quality glossy paint finish.

The frontal water curtain captures paint mist, and the air flow created by the fan additionally draws in contaminated air.
Video. 2. Spray booth with water curtain

What happens when a spray booth operates with a water curtain?

When operating a water spray booth, the following processes occur:

  • removing paint particles and dust from the spray area
  • removal of paint aerosol and eliminating the possibility of its spread to surrounding areas
  • providing ideal conditions for creating high quality coatings
  • the removed air is cleaned of mechanical particles of paint and part of aerosol vapors and released into the atmosphere.

How to care for a spray booth with a water curtain?

The first thing to do when operating a chamber with a water curtain is replacing the water. They change it depending on the degree of contamination in the cabin.

How quickly the chamber gets dirty depends both on the intensity of painting, that is, how much paintwork is applied per shift, and on the paint guns used. For spray guns with a low material transfer coefficient, a lot of paint is spent on fogging, which means more paint settles in the cabin. If the water is dirty, it will be less able to capture paint mist and dust.

How do you clean water from paint in a spray booth with a water curtain?

In small factories, water is simply poured into the sewer, which is basically impossible, and the accumulated paint at the bottom is scooped out with shovels and other available means.

“Advanced” companies use coagulants and a collection of paint waste to remove paint. The addition of a coagulant allows the paint to turn into flocs, which precipitate or float to the surface as flakes. Flakes are removed manually or using a waste collector.

How is air purified in a spray booth with a water curtain?

Water spray booths have three levels of air purification from paint:

  1. At the first level, air purification is carried out using a frontal water curtain. A stream of water flows down this part of the chamber in a continuous and continuous stream.
  2. At the second level, internal air purification occurs; here the main filtration and purification of the air from paint waste takes place. Depending on the design of the spray booth and the manufacturer, there are various internal air purification systems.
  3. At the third level, dry filtration is carried out - the air is cleaned of remaining paint particles and protects the fan blades from paint sticking.

Water chamber design diagrams

Different manufacturers of spray booths have different filtration systems; for example, here are several diagrams of water spray booths.

What length and width should I choose for a spray booth?

If maximum length the parts to be painted are 2.7 meters, then the required length of the cabin is 3 meters, and if it is 1.8 meters, then 2 meters are needed.

If you want two painters to work in the booth, then multiply the numbers by two, at least.

The depth of the cabin depends on the size of the room in which the painting will be carried out. If the painter will be inside the cabin, then focus on maximum dimensions painted parts.

If the room is, for example, 4 meters, and the cabin is 3 meters, then the cabin can be installed without side walls. Again, if two cabins are installed side by side, then side walls are required so that there is no dust from the adjacent chamber.

Example of a paint booth from furniture production

Here are photos of a paint booth that were taken during a tour at a real operating enterprise.
