Carbon fiber filter cartridge applied to pretreatment of high-boiling-point substances in paint mist in coating industry

Abstract

The embodiment of the invention discloses a carbon fiber filter cartridge applied to pretreatment of high-boiling-point substances in paint mist in the coating industry. The carbon fiber filter cartridge applied to pretreatment of high-boiling-point substances in paint mist in the coating industry comprises a front cover plate, a cartridge body, a main fan, a rear cover plate, a carbon fiber felt, a fixed mesh enclosure, a differential pressure gauge, a warning device and a controller; a plurality of filtering holes are formed in the cartridge body, the carbon fiber felt is arranged on the cartridge body, the carbon fiber felt is sleeved with the fixed mesh enclosure, and the fixed mesh enclosure is used for fixing the carbon fiber felt; and the front cover plate is arranged at one end of the cartridge body, the rear cover plate is arranged at the other end of the cartridge body, an air inlet pipeline is arranged on the front cover plate, and the main fan is arranged on the air inlet pipeline. According to the carbon fiber filter cartridge applied to pretreatment of the high-boiling-point substances in the paint mist in the coating industry, the complexity of a whole waste gas treatment system is reduced, meanwhile, the treatment cost is reduced, and miniaturization is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the field of environmental protection technology, in particular to a carbon fiber filter cartridge used for pretreatment of high boiling point substances in paint mist in the painting industry. Background technique [0002] In the painting industry, spraying paint is a common process that is likely to cause health hazards to the environment and human body. For this process, the paint will produce a large amount of gas containing harmful substances such as benzene, formaldehyde, toluene and other substances during the spraying process. This part of the gas gathers in the production workshop, will directly cause harm to the human body, and is directly discharged into the air , will produce air pollution to the atmosphere, affect the surrounding ecological environment, especially have a direct impact on air quality. [0003] At present, the common air pollution prevention and control measures adopted by ...

Problems solved by technology

[0004] However, when activated carbon adsorbs the remaining organic matter in the above-mentioned waste gas, there are the following problems: due to the different sizes of the adsorption pores of the activated carbon, there are few micropores, and the adsorption effect of the large pores on the high-boiling point organic matter is not good, resulting in the treatment efficiency of the remaining organic matter in the above-mentioned waste gas. Low, increased the burden of subsequent treatment procedures; at the same time, in order to improve the treatment of high boiling point organics, the current common practice is to increase the amount of activated carbon or improve the structure of the adsorption channel, resulting in the existing adsorption device complex structure, large volume, At the same time, the subsequent adsorption process has to take into account the adsorption of high-boiling point organics, making the entire adsorption system huge and numerous processes
