Electric bag composite deduster

Abstract

The invention discloses an electric bag composite deduster which comprises an electrostatic dedusting unit, a cloth bag dedusting unit, a vertically lifting spray-blow ash cleaning device and a smoke diversion device, wherein an upper transmission shaft of the vertically lifting spray-blow ash cleaning device and a lower transmission shaft of the vertically lifting spray-blow ash cleaning device are respectively arranged at the top and the bottom of a casing of the electrostatic dedusting unit, an upper left chain wheel and an upper right chain wheel are respectively arranged at the left end and the right end of the upper transmission shaft, and a lower left chain wheel and a lower right wheel are respectively arranged at the left end and the right end of the lower transmission shaft. The upper left chain wheel is connected with the lower left chain wheel through a left chain, the upper right chain wheel is connected with the lower right chain wheel through a right chain, a left end cover a spray-blow pipe and a right end cover of the spray-blow pipe are respectively arranged on the left chain and the right chain, and the spray-blow pipe is located between an anode plate and a cathode line. A diameter-expansion air outlet pipe of the smoke diversion device is arranged on an air inlet pipe, an adjusting valve is arranged on the diameter-expansion air outlet pipe, an air inlet of the air inlet pipe is located in a smoke inlet of the electrostatic dedusting unit, and the diameter-expansion air outlet pipe on the air inlet pipe is located below a cloth bag arranged in a casing of the cloth bag dedusting unit.

Description

technical field [0001] The invention relates to an electric bag composite dust collector, which comprises an electrostatic dust removal unit and a cloth bag dust removal unit. Background technique [0002] An existing electric bag composite dust collector includes an electrostatic dust removal unit and a bag dust removal unit, and the electrostatic dust removal unit and the bag dust removal unit are connected in series as a whole. The electrostatic precipitator unit includes a shell, a flue gas inlet, an anode system, a cathode system, and an ash hopper. The anode system consists of anode plate, anode suspension device and anode rapping device. The cathode system contains cathode wire, cathode frame and cathode rapping device. The dust cleaning of the electrostatic precipitator unit is mainly realized by the anode rapping device and the cathode rapping device. Since the rapping methods of the anode rapping device and the cathode rapping device belong to the mechanical rap...

AI Technical Summary

Problems solved by technology

Since the flue gas is subjected to electrostatic precipitator first and then bag dust removal, the burden of the front electrostatic precipitator is heavy while that of the rear bag dust collector is light, that is, the dust removal loads of the electrostatic precipitator unit and the bag filter unit are unbalanced.

If you want to achieve the ideal dust removal effect, you must increase the margin when selecting the dust collector, so that the model will increase, and the project investment will increase, resulting in increased investment and use costs, resulting in waste of investment.
