Basic equipment:

Prefabricated body and settling bath made of galvanized steel with large quantity longitudinal, transverse and vertical stiffeners.

Double cascade water curtains

Frontal curtains of both cascades (those through which water flows) have a quick-detachable design. This not only provides full access to the inside of the chamber for maintenance, but also makes it technically possible to narrow the gap between the bottom edge

curtains and water in the bathroom below. For the upper cascade, this is the lower cascade bath, 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 excluded;
water falling from the lower edge of the water curtain creates a dense stream, additionally purifying the air from suspensions, which eliminates the need to install water sprinklers;
the air flow rate after getting inside the spray booth is reduced by 4-5 times, which allows suspensions to settle into the settling bath, increasing the degree of purification of the exhaust air.
The location of the bath for placing the pump is universal (to the left or to the right of the chamber). In this way, the service side can be selected during installation.
The location of the service area outside the chamber allows visual control of operation and avoiding external contamination of the pump, which leads to its overheating and premature failure.
Gate valves located outside make it easy to regulate the flow of water in the water curtains, as well as to quickly drain water from the chamber with a regular pump during its scheduled maintenance.
stainless steel pump,pumps clumps of sludge paintwork materials with a diameter of up to 35 mm, as well as a built-in overheating protection system.
Circulating conduit system, including a water circulation valve, an automatic water drain valve, all necessary hoses, passage assemblies, flanges, clamps and other installation materials

Spray booths with dry filtration

The structure is made from sandwich panels . The walls of the sandwich panels are made of powder-coated galvanized sheets 30 mm thick, the space between which is filled with foamed polyurethane foam.

Filtration polluted air is carried out using a set of fiberglass (floor) and labyrinth (in chambers without carbon elements) filters type "paint stop" (Paint-stop) 50 mm thick, installed frontally. In order to reduce the concentration of dust in painting area and storage and drying areas we recommend using

The use of spray booths with a water curtain improves the quality of the finish and eliminates the impact of harmful substances on humans and the environment, which is determined by various factors related to the size of the products to be painted, the volume and type of sprayed material, the duration of use of spray booths, and security requirements. environment, labor costs. For all cases, it is possible to select the appropriate spray booth with a water-filtered front suction system that ensures the sedimentation of solid particles. In this case, the product must be between the operator and the active curtain of the chamber. When choosing a stand, it is necessary to evaluate the size of the product to be painted and the need to use a cabin for the simultaneous work of several operators.

Distinctive characteristics:

The camera is the leader in sales in Russia in this segment, occupying more than 40% of the market.

The principle of operation of water cabins:

With the help of a fan installed on the roof of the chamber, a vacuum is created, which ensures the suction of air, with the help of a water curtain (pos. 1), solid paint pigments are deposited. Washing with water and additional dry filtration (D) allows aerosols to be captured and deposited in the collection bath. The pump (pos.2) circulates water through the baths (A, B, C), overflowing from which forms water curtains. Some versions have two additional side curtains to optimize the first filtration stage. The chamber consists of galvanized metal panels, bolted together. Side panels and partitions are load-bearing, a centrifugal fan is mounted on the roof. Execution in various modifications: suction front only, suction front with additional walls and extended roof plus bottom baths equipped with a grate, also available in two heights. For fine cleaning chemical composition air, it is recommended to use a stand-alone KARB coal plant.

Spray booth with dry filters

Due to its design, when painting in a dry spray booth, excess paint mist and polluted air are removed from the paint application area, while cleaning it. All this works with the right choice of fan.

What Happens When a Spray Booth Works with Dry Filters

During the operation of a dry spray booth, the following processes occur:

removal of paint particles and dust from the spray area
removal of paint aerosol, while preventing its spread to adjacent rooms
conditions are provided for obtaining paintwork High Quality
the air that is removed from the painting area is cleaned of mechanical paint particles that remain in the filters and is released into the atmosphere.

How is air filtered in a dry spray booth?

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

What are dry booth filters?

Filters for a dry spray booth are:

Cardboard filter

The principle of operation of the cardboard filter is as follows - particles of paint and varnish hit the inner wall of the filter several times and settle on it, and the air continues to move by inertia, while there is no loss of air velocity 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 a 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 waste paint. 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 glass fiber filter is made of fluffy woven fiberglass impregnated with a special compound. The filter retains paint mist particles.

The glass fiber filter can be used as the only or second level of air mist removal.

In the variant of the second level of filtration, this filter is installed behind the cardboard filter. Often, a glass fiber filter in a roll is installed on the floor in car chambers, hence its second name is “floor”.

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

How long does a dry booth filter last?

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

The calculation of the "lifetime" of a dry filter is based on the following components:

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

Dry filter lifetime calculation example

For example, you again have a 2-meter dry painting booth, the consumption of paintwork 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 54 kg of paint. It turns out that one filter change is enough for 54/8 = 6.8 days, that is, for about a week of work. And if you bought a filter roll, then it will last for a month, and you can count it yourself in money.

Spray booth with water curtain

Spray booth with water curtain ensures the maximum level of cleanliness and dust removal in the painting area. All this allows you to create ideal conditions for obtaining a high-quality glossy paintwork.

The frontal water curtain captures the paint mist, and the airflow created by the fan additionally draws in polluted air.

What Happens When a Water Curtain Spray Booth Works

During the operation of the water spray booth, the following processes occur:

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

How to maintain a spray booth with a water curtain?

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

How quickly the chamber becomes dirty depends both on the intensity of painting, that is, how much paintwork is applied per shift, and on the spray guns used. On spray guns with a low material transfer coefficient, a lot of paint goes into fogging, which means more settles in the cabin. If the water is dirty, then it captures paint mist and dust worse.

How is water cleaned 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 improvised means.

At "advanced" firms, coagulants and a collection of paint and varnish waste are used to remove paint. The addition of a coagulant makes it possible to turn the paint into flakes that precipitate or float to the surface as flakes. The flakes are removed manually or with a waste collector.

How is the air cleaned in a spray booth with a water curtain?

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

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.
At the second level, internal air purification takes place, here the main filtration and purification of air from paint waste takes place. Depending on the design of the spray booth and the manufacturer, there are various systems for internal air purification.
At the third level, dry filtration is carried out - the air is cleaned of the remaining paint particles and protects the fan blades from paint sticking.

Schemes of structures of water chambers

Different manufacturers of spray booths have different filtration systems, for example, we give several schemes of water spray booths.

What length and width to choose a spray booth?

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

If you want two painters to work in the cabin, 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 is inside the cabin, then be guided by the maximum dimensions of the parts to be painted.

If the room, for example, is 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 the side walls are mandatory so that there is no spray from the adjacent chamber.
