AI Technical Summary

Technical Problem

Existing mechanical vacuum pump dust removal systems have low temperature resistance, requiring the installation of flame arrestors, which leads to high filter bag resistance, increased filtration area, and increased equipment volume.

Method used

The dust collector adopts high-temperature resistant metal filter bags, including a dust removal assembly, a blowing assembly, and a filter bag assembly. It utilizes the high-temperature performance of the metal filter bags to eliminate the need for a pre-fire arrestor and achieves efficient filtration and dust removal through the dust removal and blowing assembly.

Benefits of technology

The filtration resistance was reduced, the filtration area and volume of the equipment were decreased, the pre-flame arrestor was eliminated, and the stability and efficiency of the equipment were improved.
