Description

Technical Field

[0002] Painting waste gas treatment refers to the treatment work of adsorbing, filtering and purifying waste gas generated in the industrial production process. In order to transport the painting waste gas to the purification device, an air suction pump is usually used to suck the waste gas into the air supply device, and then the air supply device transports the waste gas to the purification device through a pipeline. After searching, an air supply device for treating organic waste gas disclosed in application number CN202021392436.7 records that the waste gas enters the box body through the air inlet pipe, and the spray mechanism sprays the organic waste gas to reduce dust, so as to prevent the dust and impurities in the organic waste gas from adhering to the inner wall of the pipe, blocking the pipeline and affecting the normal use of the device. The organic waste gas after dust reduction is output to the outside of the device through the air outlet pipe, which solves the problem of pipeline blockage during the air supply process.
