A mobile lens pole electrostatic precipitator with rotating dust cleaning brush

Abstract

The invention discloses a mobile lens pole electrostatic dust collector with a rotary ash removal brush, which belongs to the field of flue gas dust removal in air pollution control and solves the problems that a lens-type electrostatic dust collector has large secondary dust emission and low efficiency of dust collection in the prior art. The mobile lens pole electrostatic dust collector with the rotary ash removal brush comprises a positive corona pole, a negative corona pole and a lens pole in a lens-type electric field; the lens pole consists of a plurality of lens pole plates with rectangular ports; two ends of the lens pole plate are connected to an internal transmission chain and are in rotary motion along with the internal transmission chain; in the lens-type electric field, each rectangular port of the lens pole plate becomes a lens port unit; a lens port consists of a row of lens port units aligned vertically; the mobile lens pole electrostatic dust collector further comprises the rotary ash removal brush arranged below a lens-type electric field dust collection area; bristles on the rotary ash removal brush are closely compressed at the side face of the lens pole plate; a lower decelerating motor provides a power for the rotary ash removal brush by a rotary power transmission device of the ash removal brush so that the ash removal brush is rotated to move.

Description

Technical field [0001] The invention relates to an electrostatic precipitator, in particular to a movable lens electrode electrostatic precipitator with a rotating dust cleaning brush, belonging to the field of flue gas dust removal in air pollution control. Background technique [0002] In order to better protect the ecological environment and people's health, environmental protection agencies in some provinces and cities have successively issued stricter air pollutant emission standards. For example, the DB11 / 139-2007 "Boiler Air Pollutant Emission Standard" issued by the Beijing Environmental Protection Bureau stipulates that the maximum allowable emission concentration of smoke and dust from newly built, expanded, and rebuilt power station boilers and industrial boilers is 10mg / dNm 3 ; Since July 1, 2008, the maximum allowable emission concentration of smoke and dust from in-use power station boilers is 20mg / dNm 3 , The maximum allowable emission concentration of dust from ind...

AI Technical Summary

Problems solved by technology

However, due to the relatively large amount of secondary dust generated when the lens plate is vibrated and cleaned, part of the PM10 and dust with an aerodynamic equivalent diameter greater than 10 microns captured by the lens plate are carried out by the flue gas The electric field causes the PM10 emission concentration and dust emission concentration of the electrostatic precipitator to suddenly increase at this time, which in turn leads to an increase in the time and daily average values ​​of the two, which seriously affects the dust removal efficiency of the electrostatic precipitator
