Dry type paint waste gas dust remover

Abstract

The invention discloses a dry type paint waste gas dust remover, which comprises a waste gas absorption cover, a first-stage dust removal filter box and a second-stage dust removal filter box, a firstpumping fan is arranged on a pipe body of a gas inlet conveying pipe, a second pumping fan is arranged on a pipe body of a circulating pipeline, and a third pumping fan is arranged on a pipe body ofan exhaust conveying pipe. A centralized collection box is inserted into the bottom of the primary dust removal filter box in a drawable mode, a striking supporting frame is fixed to the position, corresponding to the top wall of the paint chamber, above the primary dust removal filter box, a pair of striking assemblies is arranged on the striking supporting frame, and a circular dust filter screen is additionally arranged in a pipe opening in the left end of the circulation pipeline. The scraper is attached to the surface of the circular dust filter screen; and two activated carbon adsorptionfilter elements are arranged in the box body of the secondary dust removal filter box in a vertical drawable type. The waste gas dust remover is improved in practicability and universality.

Description

technical field [0001] The invention relates to the related technical field of paint emission treatment, in particular to a dry paint waste gas dust collector. Background technique [0002] Paint is a chemical mixture coating that can firmly cover the surface of objects for protection, decoration, marking and other special purposes; in the process of furniture production, on the one hand, it is to protect the furniture wood from corrosion during use, on the other hand, it is to pursue The beauty of the furniture will be painted on the surface of the furniture. [0003] However, during the painting process of furniture, the woodworking materials need to be polished first, and then sprayed. A large amount of dust will be generated during the treatment process. In the existing technology, only simple dust removal is done for the paint exhaust gas. It is difficult to meet the emission standards. The dust filter used in the dust removal process is prone to the problem of poor fi...

Problems solved by technology

[0003] However, during the painting process of furniture, the woodworking materials need to be polished first, and then sprayed. A large amount of dust will be generated during the process. In the existing technology, only simple dust removal is done for the paint exhaust. It is difficult to meet the emission standards. The dust filter used in the dust removal process is prone to the problem of poor filtering effect due to the blockage of the mesh after long-term use. It cannot guarantee the filter efficiency of the dust filter and the comprehensiveness of the dust removal range. The same cannot be guaranteed, and the dust is easy to adhere to the top and side walls of the treatment chamber. Not only that, but the existing technology also has the technical defect that the filter element cannot be replaced. The practicability of the exhaust gas dust collector is not good, and the applicability is poor. Redesign
