Problems solved by technology

[0003] Patent No. CN201710504205.7 discloses an AB bag filter. The main feature is that the bag filter A and the bag filter B are juxtaposed. The common ash inlet valve in the dust collection pipe is opened and closed to control the two sets of bag filters to shut down and run in turn. Regeneration, but this patent actually uses two bag filters to remove dust in parallel, the filtration efficiency has not been improved, and only one gas can be filtered, and the bag is supported by a fixed frame body, when cleaning the outside of the bag It is difficult to remove the dust by disassembling the cloth bag, and the connection between the venturi tube and the cloth bag is poor

Abstract

The invention discloses a bag dust removal device with low air leakage rate for environmental dust removal, which belongs to the technical field of bag dust removal, and comprises a dust filter cylinder, a bag dust filter mechanism, a partition and a dust collection cylinder. A bag dust filter mechanism is installed in the middle of the dust filter cylinder. The lower end of the dust filter tube is provided with a dust collection tube, and a partition is installed in the middle of the dust filter tube. The partition plate divides the inner cavity of the dust filter tube into an upper cavity and a lower cavity. An air inlet and an air outlet, the first air inlet communicates with the lower chamber, and the air outlet communicates with the lower chamber. The filtration efficiency is improved through the double-layer filter, and the characteristics of the deformable vibration of the spring are used to facilitate and quick dust removal, strengthen the connection, improve the sealing, and prevent dust leakage.

Description

technical field [0001] The invention relates to the technical field of bag dust removal, in particular to a bag dust removal device with low air leakage rate for environmental dust removal. Background technique [0002] The dust bag is called the heart of the bag filter, and it is generally called a dust bag or a filter bag. The dust bag is a key part in the operation of the bag filter. Usually, the cylindrical filter bag is hung vertically in the filter. The fabric and design of the dust bag should be as efficient as possible, easy to remove dust and durable. The selection of dust bag is very important, it directly affects the dust removal effect of the dust collector, the selection of dust bag should be selected from the following aspects: gas temperature, humidity and chemical properties, particle size, dust concentration, filtration wind speed, cleaning dust and other factors. [0003] Patent No. CN201710504205.7 discloses an AB bag filter. The main feature is that the...
