Yixin environmental protection equipment-dust-free spray booth Affordable price: 0-50000 yuan, see below (for reference only, the specific price depends on the degree of cooperation in customized specifications) Overview: Dust-free spray booth (spray booth) room body adopts sub-parent plug-in thermal insulation spray wall panel, which has good sealing and thermal insulation performance. The side of the room body is equipped with a working door to facilitate the entry and exit of staff. Aluminum alloy edge gate, the center of the door is equipped with an observation window, which can observe the dynamics of the room at any time. Choose low noise and high air volume fan to ensure the perfection of the painting effect; dust-free spray booth can be divided into dry spray booth (more common) and wet spray booth (water curtain or spray booth) according to the filtering principle. Dust-free spray paint room (paint room) paint room is generally used to spray and baking furniture (car) paint, therefore, the most accurate description of the paint room should be "spray paint room". When painting, the outside air is sent to the roof by the fan after being filtered by the primary filter, and then enters the room after being filtered and purified by the top filter. The air in the room is of full drop type and flows downward at a speed of 0.2-0.3 m/s, so that the paint mist particles after painting cannot stay in the air and are directly discharged out of the room through the air outlet at the bottom. In this way, the air in the room is more than 98% clean when painting, and the air sent has a certain pressure, which can form a constant airflow around the car to remove excessive paint, so as to maximize Ensure the quality of paint. Spraying process is widely used in furniture production to finish furniture. The spraying process has high production efficiency, and the formed paint film is uniform and fine, smooth and smooth, and has high adhesion. However, the paint atomized by high-pressure air during spraying and construction has formed a large amount of paint mist. Paint mist is composed of paint particles and solvent, the proportion of paint mist is very small, floating in the air. Paint mist deposition on the surface of the workpiece will affect the quality of the workpiece, the operator inhaling paint mist is also harmful to health. Cleanliness is an important indicator to measure the quality of the spray baking room, and these 1 indicators are guaranteed by the air purification system. Dust-free spray booth (spray booth) is based on a closed room, plus a set of air purification system. The whole air filtration of dust-free spray booth (spray booth) is grade II filtration, that is, the combination of primary air inlet filtration (currently common below 300 mesh) and top high efficiency filtration (currently common below 600 mesh). The top filter material is arranged at the bottom of the static pressure chamber and supported by a top net. The top net is of high-quality stainless steel structure, and the top net is fixed with fishtail screws and pressure plates around. No rust on the whole, easy to replace the top cotton. With the improvement of coating operation requirements, many furniture manufacturers use water curtain spraying room to eliminate paint mist and improve the spraying construction environment. Water curtain spray booth (hereinafter referred to as the water curtain machine) used to be single curtain type, but at present most of them are double curtain type. After the paint is atomized by compressed air, it is sprayed from the spray gun to the surface of the workpiece. The excess paint mist flows to the exhaust port below the water curtain plate under the negative pressure of the water curtain machine. The air flow in the entire spraying area flows obliquely downward to the exhaust port. Woodworking machinery manufacturers take into account the better organization of the air flow of the spraying environment and the size of the water curtain plate is limited by the width of the stainless steel plate, the water curtain plate is designed as a double curtain type. There is no essential change between single curtain type and double curtain type. The double-curtain type adds an exhaust port in the middle of the water curtain, and the exhaust port in the middle makes the flow of paint mist generated from the spray gun to the exhaust port form a parallel flow of air flow. The air flow is advantageous for spraying a workpiece with a large area in the horizontal direction, which can reduce the interference of paint mist on the sprayed workpiece and improve the quality of the paint film. What are the shortcomings of the water curtain spray booth: Some shortcomings of 1 products are inevitable, and so is the water curtain machine. Its biggest disadvantage is high humidity during operation. Due to the use of water as an adsorbent for paint mist, in order to improve the adsorption performance, the water must be circulated at high speed, and the air containing paint mist must be sprayed and cleaned. A large amount of water is sprayed and volatilized in the water curtain machine. Will increase the humidity of the spray booth. We all know that many coatings in furniture coating are not suitable for construction in high humidity environment, high humidity will affect the quality of the film and the speed of drying. Generally, a series of measures such as increasing the exhaust air volume and conveying sufficient dry and clean air are used to reduce the humidity in the spray painting environment. Some countries do not use water curtain machine, which is mainly related to the environmental protection law of the place. Some countries take into account the difficulty of water pollution treatment, so many laws and regulations on the discharge of sewage strictly control, do not allow the water curtain machine sewage untreated discharge, so furniture enterprises often avoid regulations, the use of dry filtration method to absorb paint mist. According to our current situation, the amount of sewage produced by the water curtain machine is relatively small. When the paint residue in the sewage is filtered, the impact of discharge on the environment is still relatively small. After the water curtain machine adsorption of solvents and coatings in the air, after all, than the original arbitrary emissions is a progress. Although the water curtain machine has its shortcomings, it has many advantages: low investment, low operating cost, repeated washing by water circulation, and extremely low cost of absorbing paint mist. The treatment effect is good. If the water curtain machine is adjusted well, the treatment efficiency can reach more than 85%. As the water curtain machine has the above characteristics, it will not be eliminated in a relatively long period of time. The high-efficiency filter material adopts 600-mesh precision filter cotton, which has a multi-layer structure, and the oily interlayer in the middle has extremely high adhesion, which can ensure the air cleanliness to reach a dust content of ≯ 1.5mg/m3 and a maximum dust particle ≯ 4μm m. Its main technical indicators are: Model SP600G Original resistance 21Pa Final resistance 230Pa Average capture rate 96% Dust holding capacity 419g/m2 Thickness δ22 ㎜ dust spray booth working principle: As the name implies, it is to spray paint the filtered spray paint object in a room, which is now also called the paint room. Traditional painting is to spray the appliance (car, furniture, etc.) in the open air with a spray nozzle, but this way is for large devices. Dust-free paint room For example, the dust in the air will be mixed in the paint during the painting process, thus reducing the quality of the paint; Uncertain waste of paint, and the painting area will be very dirty; For the staff, on the one hand, it will be very dirty, on the other hand, it will be harmful to the body by inhaling a large amount of paint mist. Later, people wanted to set the spray paint within a certain range, and the earliest spray booth-exhaust spray booth was produced. In China, the spray booth was first produced in Chengdu in the 1990 s. The three keys of the exhaust spray booth are: 1. Ventilation ---- the key to the work of the exhaust spray booth 2. Filter-filter small particles in the air 3. Exhaust-exhaust of waste air and entry of new air The specific principle is: Wind (outdoor air)-spray booth filter cotton-spray booth-use spray equipment to spray paint-exhaust fan (discharge of paint mist) The weakness of this spray booth still exists: 1. The filter cloth is easy to scratch, dust is easy to enter 2. Easy to outdoor unclean air 3. Not environmentally friendly, waste paint 4. Need to clean up frequently, regularly remove the dirt on the filter cloth Our company declares: the above price is only used for reference in purchasing this kind of products.
