Detailed ways:

In order to further illustrate the above-mentioned purpose, technical solutions and effects of the present utility model, the utility model is illustrated below in conjunction with the accompanying drawings and relevant known technical knowledge through the embodiments:

As shown in Figure 1-2, this kind of water curtain paint spray booth includes paint spray paint conversion damper 1, primary filter device 2, air inlet 3, air supply system 4, heating system 5, and lighting system 6. , one-time adsorption glass wool 7, ground grille 8, top filter device 9, static pressure chamber 10, operating room 11, activated carbon adsorption device 16, exhaust system 17 and paint spray circuit control system, which is characterized by: Wind system 17 one sides, be provided with water curtain adsorption device 15 below the activated carbon adsorption device 16 of setting; Sealing plates 27 are respectively arranged on the inner cavity wall, and the inlet of the air exhaust channel is connected with the water curtain adsorption port 28 at the lower end of the water curtain device, and the water curtain adsorption port 28 is connected with the underground air discharge channel of the operating room 11, and the water curtain The outlet of the exhaust channel of the adsorption device 15 is connected with the activated carbon adsorption device 16 and the exhaust system 17; the water curtain adsorption device 15 is provided with a labyrinth gas-water separation device in the exhaust channel;

The water curtain device set in the described water curtain adsorption device 15 is to change the original ventilation channel under the equipped water curtain adsorption device 15 floor into the sump 26; the top of the water curtain device is provided with an overflow tank 20. A water curtain plate 19 is provided under the overflow of the overflow tank 20, and the water curtain plate 19 is arranged above the sump 26; the water inlet pipe of the water pump 25 is connected with the sump 26, and the water outlet of the water pump 25 is supplied by water The pipeline 21 communicates with the overflow tank 20, and the water supply pipeline 21 is provided with a regulating valve 24; the water pump 25 pumps the water in the sump 26 to the overflow tank 20 on the top of the water curtain device, so that the water is The overflow in the overflow tank 20 flows down along the water curtain plate 19 to form a water curtain;
