Dust recovery device

Abstract

The invention belongs to the technical field of environmental protection and resource reutilization, and particularly discloses a dust recovery device. The device comprises a smoke dust pipeline, anda bag type dust remover is arranged at one end of the smoke dust pipeline; a pre-dust removal mechanism is further arranged on the smoke dust pipeline; the pre-dust removal mechanism comprises a plurality of louvers which are distributed in the axial direction of the smoke dust pipeline. Each louver comprises a plurality of perforated louver blades which are arranged in parallel, the perforated louver blades are obliquely arranged, and the perforated louver blades are distributed in the radial direction of the smoke dust pipeline; rotating shafts and high-pressure sprayers are arranged betweenthe adjacent louvers, the rotating shafts extend in the radial direction of the smoke dust pipeline, the rotating shafts are rotationally connected with the smoke dust pipeline, and the rotating shafts are coaxially and fixedly connected with cams; a driving mechanism is arranged outside the smoke dust pipeline, and the driving mechanism comprises a driving plate and a sheave; a spraying switch is fixedly connected to the outer wall of the smoke dust pipeline. By the adoption of the dust recovery device, the amount of gas dust in the bag type dust collector can be reduced, the dust removal period is prolonged, and then the service life of a filter bag of the bag type dust collector is prolonged.

Description

technical field [0001] The invention relates to the technical field of environmental protection and resource reuse, in particular to a dust recovery device. Background technique [0002] At present, in the domestic flue gas dust removal system, the dust recovery equipment generally used is relatively simple, and bag type dust collectors are mostly used. The filter bag in the bag filter is made of textile filter cloth or non-woven felt, and the dust-containing gas is filtered by the filtering effect of the fiber fabric. When the dust-containing gas enters the bag filter, the particles with large particles and large specific gravity Dust settles down due to the effect of gravity and falls into the ash hopper. When the gas containing fine dust passes through the filter material, the dust will be blocked and the gas will be purified. [0003] However, when the bag filter is in use, it needs to be cleaned in time to avoid affecting the dust removal efficiency. When the dust cont...

[0003] However, when the bag filter is in use, it needs to be cleaned in time to avoid affecting the dust removal efficiency. When the dust content in the gas is large, the cleaning cycle needs to be adjusted to be shorter. Frequent cleaning of the filter bag will make the bag filter Reduced bag life in dust collectors
