Cylindrical sacks at different positions inside the filter-bag zone filter dust load evenly, and dust filteration efficiency is high.
Description
Technical field
The utility model relates to a kind of coal-burning power plant large-scale steam boiler tandem static-Bu bag complex dust collector, particularly the wind field optimization device of a kind of tandem static-Bu bag complex dust collector.
Background technology
The 1065T/H CFBB that the assembly of the 300Mw of coal-burning power plant steam-driven generator is used will be discharged the flue gas that contains in a large number more dust when operation.The dust of discharging can cause serious pollution to ecological environment on every side.For alleviate and eliminate above-mentioned boiler smoke to around environment, be connected with deduster to remove the dust in the flue gas at the exhanst gas outlet of above-mentioned boiler.
In deduster, the electrostatic precipitator treating capacity is large, and the pressure loss is little, but electrostatic precipitator is bad to the little high resistivity dust removal effect of particle diameter, so the total dust removing effects of electrostatic precipitator is not fine, boiler flue gas outlet only is connected with electrostatic precipitator and is difficult to make smoke evacuation up to standard.Sack cleaner is to good, the total better dust removal effect of removal effect of the little particularly high resistivity dust of particle diameter, but the smoke treatment amount is not very large, and the pressure loss is larger.
In mid-term in last century, people have proposed static that electrostatic precipitator and two kinds of dedusters of sack cleaner are combined with each other-Bu bag complex dust collector, and tandem static-Bu bag complex dust collector is arranged in static-Bu bag complex dust collector.Tandem static-Bu bag complex dust collector has the square box shape housing, the front end of housing has air inlet, airflow-distribution board is arranged in the air inlet, there is the gas outlet rear end of housing, leading portion in the housing is by being Z-shaped by many groups of sections arranged vertically or the strip dust collecting pole plate of C shape and have the electric field region that the linear discharge electrode of prickle forms, the front side of electric field region links to each other with air inlet, the filter bag district that back segment in the housing has the cylindrical shape cloth bag by a plurality of vertical lower end closed to rearrange, the upper nozzle of cylindrical shape cloth bag links to each other with the gas outlet, there is the ash bucket electric field region in the housing and the below in filter bag district, and there is ash hole the lower end of ash bucket.
During use, the gas that contains dust enters in the housing from air inlet, enter the gas that housing contains dust first through electric field region in flowing, isolate most of dust in the gas that contains dust with the mode of electrostatic precipitation at electric field region, the larger dust of particle diameter particularly, discharge contains the gas of the less dust of a small amount of particle diameter, the gas that contains the less dust of a small amount of particle diameter flows into the filter bag district again, in the filter bag district take cloth bag as filter medium, isolate the less dust of particle diameter, peace and quiet gas is discharged through the gas outlet, and isolated dust is discharged through ash hole.
In above-mentioned tandem static-Bu bag complex dust collector housing, electric field region dust collecting pole plate area is larger, the cylindrical shape cloth bag quantity in filter bag district is more, filter area is larger, the gas that contains dust is to cross electric field region and filter bag district at the state flow that flows, and the gas that contains dust distributes larger on the impact of dedusting at the mobile wind field of electric field region and filter bag district.In the air inlet of electric field region front side airflow-distribution board is arranged, airflow-distribution board can guide the gas that contains dust to distribute comparatively even at electric field region as the wind field optimization device.In the prior art, in static-Bu bag complex dust collector housing, between the filter bag district of the electric field region of leading portion and back segment, there is not to guide the gas that contains the less dust of particle diameter at the comparatively uniform wind field optimization device of filter bag district distribution.At the back segment of electric field region, the gas after the part dedusting is to discharge between strip dust collecting pole plate arranged vertically, and wherein a large amount of gas is to enter the filter bag district from the side that the cylindrical shape cloth bag is listed as.This static-Bu bag complex dust collector in use, the wind field of the gas that contains dust in the filter bag district distributes very unreasonable, makes the cylindrical shape cloth bag filter dirt of the diverse location filter bag district in the difference of loading very large, causes efficiency of dust collection lower.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, propose a kind of in housing, have between the filter bag district of the electric field region of leading portion and back segment can guide the gas that the contains dust comparatively uniformly tandem static of the wind field optimization device-Bu bag complex dust collector that distributes in the filter bag district.
The utility model is realized with the following method.
Tandem static-Bu bag complex dust collector has the square box shape housing, the front end of housing has air inlet, airflow-distribution board is arranged in the air inlet, there is the gas outlet rear end of housing, leading portion in the housing is by being Z-shaped by many groups of sections arranged vertically or the strip dust collecting pole plate of C shape and have the electric field region that the linear discharge electrode of prickle forms, the front side of electric field region links to each other with air inlet, the filter bag district that back segment in the housing has the cylindrical shape cloth bag by a plurality of vertical lower end closed to rearrange, the upper nozzle of cylindrical shape cloth bag links to each other with the gas outlet, there is the ash bucket electric field region in the housing and the below in filter bag district, there is ash hole the lower end of ash bucket, in housing, have between the filter bag district of the electric field region of leading portion and back segment and can guide the gas that contains dust at the comparatively uniform wind field optimization device of filter bag district distribution, the wind field optimization device has even gas distribution plate vertical between electric field region and filter bag district and is standing in the gas guide board above the ash bucket below the filter bag district, be furnished with air vent at the even gas distribution plate, the aperture of the air vent of cloth on the even gas distribution plate increases from top to bottom gradually.
