A Rotary Downdraft Bag Dust Collector

Abstract

The invention discloses a rotary under-air-inlet bag-type dust remover, which comprises a rack, a bag-type dust remover body and a maintenance platform, wherein the rack is vertically arranged, the bag-type dust remover body is vertically arranged above the rack, and the maintenance platform is arranged between the bag-type dust remover body and the rack. The rotary under-air-inlet bag-type dust remover disclosed by the invention can overcome the defects of short service life, high maintenance cost, low reliability and the like in the prior art so as to achieve the advantages of long service life, low maintenance cost and high reliability.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a rotary downdraft bag filter. Background technique [0002] The mechanical rotary flat bag filter was designed by the Design Institute of the First Ministry of Machinery in 1987, and was successfully used in the bag filter for the purification of electric furnace flue gas in the capital steel mill. It was popularized and used in the whole country around 1990. Low cost, easy maintenance, widely praised by enterprises. [0003] But in practice, there are two problems. One is that the service life of the filter bag is short. The filter bag is generally damaged after being used for eight or nine months to one year. The equipment discharge exceeds the standard and the ash leakage is serious. The filter bag must be replaced immediately; The second is that in places with large temperature differences in winter, the filter bag has serious dew condensation, which causes t...

Problems solved by technology

[0003] But in practice, there are two problems. One is that the service life of the filter bag is short. The filter bag is generally damaged after being used for eight or nine months to one year. The equipment discharge exceeds the standard and the ash leakage is serious. The filter bag must be replaced immediately; The second is that in places with large temperature differences in winter, the filter bag is severely dewed, causing the filter bag to be severely blocked by the mixture of water and dust, and the gas cannot pass through, so that the equipment cannot be used.

[0004] In the process of realizing the present invention, the inventor found that there are at least defects such as short service life, high maintenance cost and low reliability in the prior art
