Double-layer outward filtering type pulse ash removal dust remover

Abstract

The invention relates to a double-layer outward filtering type pulse ash removal dust remover. The dust remover is of an upper and lower double-layer structure; the upper and lower layers of dust removal bins are provided with upper and lower independent air inlet and outlet connectors; the dust remover is composed of upper and lower completely independent dust removal functional areas; each dustremoval functional area is divided into a plurality of functional parts; and the upper dust removal functional area comprises an upper air purification chamber, an upper filtering chamber, an upper ash hopper and an upper air channel; the lower dust removal functional area comprises a lower air purification chamber, a lower filtering chamber, a lower ash hopper and a lower air channel; the upper ash hopper and the lower air purification chamber are arranged at intervals in the horizontal direction; the upper ash hopper and the lower air purification chamber share a partition wall plate; and the upper dust removal functional area and the lower dust removal functional area are partitioned through the partition wall plate. The dust remover has the advantages that an upper-layer structure anda lower-layer structure are adopted, so that the occupied area of the dust remover is not increased while the filtering area is guaranteed, and the problems of environmental protection land shortage and overhigh construction investment of the dust remover are solved.

Description

technical field [0001] The invention belongs to a dust collector, in particular to a double-layer outer filter type pulse cleaning dust collector. Background technique [0002] The environmental pressure faced by human beings is becoming more and more serious, the emission standard of dusty gas after purification is constantly improving, and the application of filter dust collectors is becoming more and more extensive. In order to meet the dust standard of the post, the air volume of the dust collection point is continuously increased; in order to meet the emission standard, the filtration air speed of the filter dust collector is continuously reduced. The large air volume and low filtration wind speed make the floor area of ​​the dust collector and the construction investment of the dust collector continue to increase. The environmental protection land planned in the early stage of the old factory area can no longer meet the requirements of the current ultra-low emission s...
