Double-cartridge filter

Abstract

The invention relates to a double-cartridge filter. The double-cartridge filter comprises a top cover, a purification chamber, a dust removal chamber and an ash hopper, wherein an air inlet pipe is mounted on the side wall of the dust removal chamber, and an air outlet pipe is mounted on the side wall of the purification chamber; the purification chamber and the dust removal chamber are isolated by a porous plate; cartridges are mounted at pores of the porous plate, upper ends of the cartridges are sealed and fixed with the pores of the porous plate, and the lower ends are fixed on a support reticular plate; the support reticular plate is fixed between the dust removal chamber and the ash hopper; an electrostatic generator is further mounted outside the dust removal chamber and comprises a reversing switch; electrostatic tubes are coaxially arranged in the cartridges, and lower ends of the electrostatic tubes are mounted on the support reticular plate; the electrostatic tubes are electrically connected with the electrostatic generator. The double-cartridge filter can promote dust to be attached to the cartridges rapidly, realizes efficient dust removal and can clean ash simply and rapidly.

Description

technical field [0001] The invention relates to an industrial dust collector, in particular to a filter cartridge dust collector. Background technique [0002] Cartridge dust collector is a kind of dust collector with filter cartridge as filter element and pulse injection or reverse injection; filter cartridge dust collector is mainly composed of air inlet pipe, exhaust pipe, box body, ash hopper, dust cleaning device, The structure is composed of diversion device, air flow distribution distribution plate, filter cartridge and electric control device; after the traditional filter cartridge dust collector passes the gas carrying dust into the box, it mainly relies on the Brownian motion of the dust itself and the carrying adhesion and settlement of the gas. On the ash hopper and filter cartridge; this filtering method is relatively passive, and the dust removal efficiency is low; after a period of use, the dust concentrated on the filter cartridge will block the pores, resu...
