Description

Spout room exhaust treatment device Technical Field The utility model relates to the field of waste gas treatment, in particular to a spray booth waste gas treatment device. Background In the conventional exhaust gas treatment method, the treatment of the coating exhaust gas mainly depends on a water scrubber as a core device. This approach not only requires the use of large amounts of circulating water and chemicals, resulting in long-term operating costs that continue to be at a high level. Furthermore, these water scrubber installations are often bulky and heavy, and their total weight during operation may be more than 5 tons. Thus, prolonged use of these devices may present a potential risk of damage to the roof structure of the plant, adding additional expense for maintenance and repair. Disclosure of utility model The utility model solves the technical problem of providing a spray booth waste gas treatment device which reduces the use of a water scrubber and can ensure the waste gas treatment effect. The technical scheme includes that the spray booth exhaust gas treatment device comprises a spray booth, wherein a spray booth is arranged on one side in the spray booth, a water curtain filtering mechanism is arranged on the other side in the spray booth, the water curtain filtering mechanism comprises a water curtain plate, a purifying cavity is formed on one side, away from the spray booth, of the water curtain plate, a plurality of baffles are sequentially arranged in the purifying cavity in a staggered manner from top to bottom, the baffles are obliquely arranged downwards, a water tank assembly for providing water flow for the water curtain plate and the baffles is further arranged below the water curtain plate and the baffles, a waste water tank is arranged below the water curtain plate and the baffles, the waste water filtering system is connected between the waste water tank and the water tank assembly, the waste water treatment device further comprises an air self-circulation system, an air inlet end of the air self-circulation system is communicated with the purifying cavity, and an air outlet end of the air self-circulation system is communicated with the spray booth.
