Bottom air inlet type cloth bag type dust collector

Abstract

The invention relates to a cloth bag type dust collector, in particular to a bottom air inlet type cloth bag type dust collector which is applied to treatment of electrolysis smoke in an electrolysis smoke purification system in the electrolysis aluminum industry or used for treating and recycling dust in other industries. The bottom air inlet type cloth bag type dust collector comprises a middle box body, an upper box body is arranged above the middle box body, a cloth bag and a skeleton are arranged in the middle box body, an ash hopper is arranged below the middle box body, an air inlet is arranged below the ash hopper, and a discharge outlet is formed in the side wall of the lower part of the ash hopper. The bottom air inlet type cloth bag type dust collector has the advantages and effects that air enters from the bottom of the dust collector, the occupied area of the dust collector is reduced, the distribution of air flow inside can be improved, and the dust collection and absorption efficiency can be increased; the ash removal effect of the dust collector can be increased; the stability of the dust collector is enhanced; and the dust collector is convenient to maintain.

Description

technical field [0001] The invention relates to a bag dust collector, in particular to a bottom air intake bag dust collector which is applied to the treatment of electrolytic flue gas in the electrolytic flue gas purification system of the electrolytic aluminum industry, or used in the treatment and recovery of dust in other industries. It has the characteristics of small resistance, uniform air distribution, saving space, saving investment, and strong stability. Background technique [0002] In the flue gas purification system of the electrolytic aluminum industry, the bag filter is the most important equipment, not only to filter dust and recover alumina, but also to absorb fluoride. The existing bag filter is divided into pulse bag filter and reverse blowing bag filter, both of which are side air intake, which makes the floor area of ​​the filter larger and the resistance of the filter increased. Contents of the invention [0003] In order to solve the above technica...
