Paint room with paint production waste gas treatment system, and paint production waste gas treatment method

Abstract

The invention relates to a paint room with a paint production waste gas treatment system, and a paint production waste gas treatment method. The paint production waste gas treatment system comprises a waste gas treatment chamber communicated with a paint room body. A first longitudinal channel communicated with a waste gas outlet at the bottom of the paint room obey, a second longitudinal channel communicated with the top of the first longitudinal channel, a third longitudinal channel communicated with the bottom of the second longitudinal channel, and an exhaust hole arranged at the top of the third longitudinal channel are arranged in the waste gas treatment chamber. A first spray unit is disposed in the first longitudinal channel. A second spray unit is disposed in the second longitudinal channel. A third spray unit is disposed in the third longitudinal channel. Activated carbon filter cotton is disposed at the exhaust hole. three spray treatment procedures and one activated carbon filtering procedure are added to treat the paint production waste gas, so that paint mist and peculiar odors in the paint production waste gas are removed completely, no paint mist or peculiar odors are present in the exhausted gas and pollution of atmospheric environment and threat on human health are avoided.

Description

Technical field: [0001] The invention belongs to the furniture industry, and relates to a paint room where furniture is sprayed with paint and a paint waste gas treatment technology, in particular to a paint room with a paint waste gas treatment system and a paint waste gas treatment method. Background technique: [0002] After the furniture products and their parts are finished, they must go through processes such as polishing, spraying paint and drying before they can be finished products. Spraying paint is carried out in the paint room. In addition to spraying the atomized paint on the workpiece during the spraying paint process, about 20% of the paint mist will not be able to adhere, but will be free in the air. In the existing paint room, there is usually a main body of the paint room, on which facilities such as a pressure-tight door, a supplementary fan, a water curtain machine, and a circulating pool are provided, and a sewage pipe directly connected with the outside...

AI Technical Summary

Problems solved by technology

Part of the free paint mist in the air will be absorbed by the water curtain produced by the water curtain machine, but there is still a considerable part of the paint mist that cannot be absorbed and discharged into the atmosphere from the sewage pipe, causing serious environmental pollution

In addition, when the supply fan on the existing paint room is supplying air to the room, the air in the room will flow, causing the paint mist to drift and be easily inhaled by the workers, threatening the health of the workers.

Therefore, the existing facilities in the paint room are too simple, and correspondingly, it is impossible to reasonably deal with the paint waste gas, resulting in a large amount of paint mist being discharged, causing adverse effects on the atmospheric environment and human health, and urgently needs improvement.
