Description

Technical Field

[0001] The utility model relates to a waste gas treatment device, in particular to an integrated waste gas treatment device. Background Art

[0002] Waste gas treatment is an important way to improve the quality of the atmospheric environment. At present, adsorption facilities such as activated carbon adsorption are widely used in various industrial sectors due to their unique adsorption properties. Since there are many types of characteristic factors of industrial waste gas and the pollution sources are relatively complex, the waste gas is inevitably in a state of coexistence of particulate matter, volatile organic matter, etc. Therefore, many companies choose to set up independent filtering facilities upstream of the adsorption facilities or set filter cotton at the activated carbon air inlet. The former has the disadvantages of large land occupation, high investment cost, and higher difficulty in environmental protection management in the later stage of the enterprise due to the use of independent filtering facilities. The latter has the problem of high replacement cost because the filter cotton used is easy to clog. In addition, the latter must replace the filter cotton regularly, which leads to an increase in hazardous waste (waste filter cotton) of industrial enterprises. Utility Model Content
