Organizations that paint cars often use cameras with a water curtain. They represent one of the most advanced options, allowing you to create a coating for large-sized products, such as car bodies, their parts, furniture, etc. Their design as a whole is a stainless steel room with supply and exhaust ventilation, which operates on electric motors. Home working part- heating element that heats the box to required temperature and maintaining the level of heat during work. Lighting also plays an important role, because it should create an even, intense light space without shadows.
Painting booths
What is the difference between painting chambers with a water curtain, and what is their advantage over traditional devices? In specially created conditions a mist of paint is formed, which then settles on the surface. But if in usual options If there is a danger that toxic substances or vapors will still leave the room, then in such devices they are retained with the help of water. In addition, the liquid binds volatile essential substances that are present in such a chamber. Of course, this type of filtration is not yet a guarantee of final disposal of harmful emissions, but still a significant decrease in their number.
Outdoor spray booths
There are also painting booths that operate in a closed air flow cycle; in this case, the air moves in a circle and returns to reuse. And if it is not very well cleaned before starting a new process, then small droplets of dye will enter the room, which will polymerize. This can deteriorate the properties of the enamel, however, the curtain of water traps these residues.
Painting booths with a water curtain: stages of operation
As already stated, this type cameras is similar to traditional devices. Air comes from the atmosphere into a confined space, and the suction is based on the operation of a fan. The air flow passes through many filters, and each of them performs a specific purification process. The quality of processing depends on the size of the holes in the filter material.
When the dyeing process begins, the air is heated using special heat elements. The temperature in the chamber increases. There are exit holes at the bottom of the device. They may be in different places. Through them the air flow leaves workspace which is done using fans. A water curtain is placed directly in front of the line, which removes the exhaust atmosphere from the chamber. Thus, before leaving the box, the air crosses thin wall from water, which retains dense particles - they settle in the form of a suspension.
Actually, this design is a water filter. There are other possibilities when the air for cleaning is passed not through a wall of jets, but through a special container in which water is poured. In this case, dense particles accumulate at the bottom, which then form condensation. To ensure that all harmful substances precipitate faster, a reagent is added to such a container, which speeds up the processing processes.
The most advanced painting booths of this type have several levels of cleaning. The first of them is the passage of air through a continuous curtain of water. In this case, a wall of water is created, and its speed of movement is always uniform. The second level provides better cleaning air masses from dye particles (internal cleaning). This is where complete liberation from impurities occurs. The third level is the completion of purification processes, which can be achieved through carbon-based filters or another type of dry-based filtration. At this stage, all paint particles disappear. Consequently, the fan will be protected from dye residues.
These are the main stages of operation of such cameras. This air purification system in spray booths with a water curtain helps reduce toxicity to a minimum, and therefore the use of this type of equipment is considered mandatory in those industries where the use of liquid paints and varnishes is required.
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.
What does the camera consist of?
ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline!
A spray booth with a water curtain is a closed room that is 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 works. 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. General dimensions should be: length 10 meters, width 8 meters, height 3.5 meters. The painting booth has a corresponding size: 4 meters wide and 6 meters long.
- 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. - 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. Lies on the floor metal grill over the entire surface of the room to a height of 15-20 cm.
- Walls. The walls are sheathed with corrugated sheets, and the inside is insulated; sandwich panels can be made.
- 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.
- 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.
- Air purification. It is carried out using filters and has three-level cleaning.
- Level 1 A frontal water curtain which is carried out by the flow of 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. Contributes complete cleaning air from paint particles and performs the function of protecting the fan from paint sticking.
- Lighting. Mounted LED or fluorescent lamps along the ceiling and walls of the room.
Automatic control and monitoring sensors are also installed over 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 an 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 such are pre-installed. Cameras with a water curtain and factory production work on the same principle.
Positive aspects of a DIY device
