The invention relates to a waste gas treatment system, in particular to a spray booth waste gas zero-emission treatment system and a technological process, the spray booth waste gas zero-emission treatment system comprises a collecting device, a spraying device, a dry type filtering device, a catalytic combustion device and a plurality of adsorption devices, and a gas outlet of the catalytic combustion device is communicated with a desorption gas inlet valve of the corresponding adsorption device through a gas inlet pipe; an adsorption air outlet valve of the adsorption device is communicated with a first pipeline; the air inlet pipe communicates with the air inlet end of a heat exchanger through a second pipeline, the air outlet end of the heat exchanger communicates with a third pipeline, the third pipeline and the first pipeline communicate with a spray booth through a three-way pipe, and a desorption exhaust valve is arranged on the second pipeline. According to the invention, zero emission of paint spraying waste gas is achieved, pollution of the paint spraying waste gas to the environment is completely eradicated, energy consumption of the paint spraying room is reduced, meanwhile, the heating function can be provided in winter, and the water resource saving function is achieved during spraying.
Description
technical field [0001] The invention belongs to a waste treatment system, in particular to a zero-emission treatment system and process flow of exhaust gas from a paint spraying room. Background technique [0002] At present, the various treatment processes used in the field of waste gas treatment in spray booths are waste gas collection, waste gas treatment, and the treated waste gas is directly discharged into the atmosphere. The efficiency of waste gas treatment varies according to the different equipment selected by the owner. Although after treatment, The VOCs content in the exhaust gas is greatly reduced, which also meets the national emission standards, but the pollution to the environment still exists, but the pollution intensity is reduced. In addition, most of the spray booths have requirements on the indoor temperature. The spray painting process requires constant temperature spray paint, and the exhaust gas from spray paint is discharged outside after treatment, ...
