Description

Technical Field

[0002] As industrial environmental protection standards become higher and higher, the environmental quality factors caused by industrial production are becoming more and more stringent. The emission of industrial waste gas is a major focus of air pollution. Now industrial waste gas needs to be filtered and dusted before it is discharged, so a filtering dust removal device is needed. However, the existing filtering dust removal device cannot filter the large amount of acidic and harmful gases contained in the industrial waste gas very well, and the filter in the filtering device will be blocked by dust if used for a long time, thereby reducing the service life of the filter.

[0003] The existing patent for "a combined filtering and dust removal device for environmental protection" with publication number "CN214809243U" includes a control mechanism, a dust removal mechanism, and an acid removal mechanism.
