Collective expanding dust collector

Abstract

The invention relates to a collective expanding dust collector which comprises a casing, wherein an upper casing and a dust conveying device are respectively arranged at the top and the bottom of the casing; a spraying and blowing system is arranged on the casing; an air outlet is formed at one side of the upper casing; a cover plate elevating device is arranged at the top of the upper casing; and air inlets are respectively formed at two ends of the cover plate elevating device. Cyclone settling chambers are arranged at the positions, which are close to two air inlets, at two ends in the casing; filtering bag frameworks are respectively arranged at the top and the bottom of the inner wall of the casing; a filtering bag is arranged between the two corresponding filtering bag frameworks at the top and the bottom of the inner wall; and the filtering bag is arranged between the two cyclone settling chambers. The collective expanding dust collector disclosed by the invention has the beneficial effects that dust gas is firstly separated and treated by the cyclone settling chambers; and a dust layer formed on the surface of the filtering bag by depositing is subjected to spraying and blowing treatment by the spraying and blowing system, and thus the dust removal effect is further improved. The collective expanding dust collector disclosed by the invention has the advantages of high dust removal efficiency, small maintenance amount, high treatment capacity and excellent performance.

Description

technical field [0001] The invention relates to a collection type expansion dust collector. Background technique [0002] At present, during the construction of the expressway, large flow and high concentration of dust will be generated. In order to prevent dust from polluting the environment, dust collectors are required to treat the dust. Most of them use pulse dust collectors or cyclone dust collectors. Cyclone dust collectors It is a negative pressure type, and the pulse dust collector is a positive pressure type. However, both of the above two dust collectors have the disadvantages that when the inner bag is too heavy, it is easy to block, which will cause low dust removal effect and short service life of the bag. Contents of the invention [0003] The purpose of the present invention is to provide a collective expansion type dust collector, which first separates the dust gas, and then sprays the dust layer formed on the surface of the filter bag through the blowing ...
