Description
Technical field
The utility model is related to a kind of electric-bag complex dust collectors, particularly coal-burning boiler electrostatic fabric filter.
Background technology
With the raising of environmental requirement, the treatment technology of flue gas also rapidly develops, wherein electric precipitator and sack cleaner
It is relatively conventional the two.For the flue gas of thermal power industry discharge, since wherein fly ash resistivity is high, partial particulate compared with
Carefully, the efficiency of electric precipitator is declined, and ability of the sack cleaner processing containing bulky grain flue dust is limited, and takes up an area face
Product is also larger.The compound deduster of electric bag is operated and is given birth to as a result,.
Electrostatic fabric filter combines the advantages of above two deduster, and most of dust in flue gas is first handled by electric field
Particle, then by bag filter filtration high specific resistance, fine grain flue dust, therefore dust removing effects are more preferable.But existing electric bag
Deduster mainly includes two problems.First, the efficiency of dust collection of electric field is low.Existing Electrode is set usually and airintake direction
Vertically, this results in flue gas that can first be beaten onboard after entering deduster, and circulation is not smooth；And those Electrodes are put down with airintake direction
Capable deduster again can be too fast by electric field between plate due to flue gas, and part bulky grain flue dust has little time to adsorb.Another problem is that it removes
The deashing mechanism of dirt device is complex.The purge mode of existing electrostatic fabric filter mainly has pulse jet and mechanical vibrator.This
The mechanism of two ways is all more complicated, and for filter cloth bag, rapping dedusting made of some warping resistance energy force difference materials
Also cloth bag can be caused to damage.To sum up, there are the problem of efficiency of dust collection is low and deashing mechanism is complicated for existing electrostatic fabric filter.
Utility model content
