Description

A kind of more bag dust collectors
Technical field
The present invention relates to deduster field, especially a kind of more bag dust collectors.
Background technology
In industrial dedusting field, flue gas direct emission, the dust in flue gas can cause damages to environment, generally use industry Deduster, wherein bag filter is the typical type in industrial dust collector again;Its basic principle is, in an air filtration room A certain number of cloth bags are set, and dusty gas can only pierce after cloth bag after air inlet enters air filtration room from the open end of cloth bag Flow out air filtration room, and by air outlet, since trifle in the world cannot pass through cloth bag surface, filtered gas trifle in the world just by It filters out.Current bag filter, in order to increase the air filtration amount in the unit interval, the method generally used is to increase cloth bag Quantity, or increase the length of cloth bag, this will cause the volume of bag filter to significantly increase, occupies larger usable floor area, And in fact, in order to obtain superior filter effect, the air filtration pore of cloth bag surface is very small, in general, cloth bag surface air filtration The air filtration gross area of pore is less than the cross-sectional area of cloth bag, causes filter efficiency slow, and air filtration pore is easy to block, and causes cloth bag Using effect be affected, replace and adjust inconvenient, increase maintenance cost, single filter type is difficult to ensure filtering effect Rate and effect, dedusting quality are relatively low, it is difficult to satisfy the use demand, environmental-protecting performance is poor.
Invention content
It is an object of the invention to overcome the prior art, a kind of more bag dust collectors are provided.
The purpose of the present invention is achieved through the following technical solutions:A kind of more bag dust collectors, including dust arrester, air filtration Room, flue gas input pipe, dust collector box body and dust flue, the dust collector box body bottom are welded with dust arrester, and dust arrester bottom connects Dust flue is connect, flue gas input pipe is equipped in the middle part of dust collector box body, dust collector box body bottom is equipped with primary efficient filter screen, dust collector box body Top is equipped with high efficiency particulate air, and polylith partition panel is equipped in the dust collector box body between high efficiency particulate air and primary efficient filter screen, every Disconnected plate will be divided into multiple air filtration rooms inside dust collector box body, dedusting plate, dedusting plate upper surface are mounted in each air filtration room It is connected with dust-removal cloth-bag, it is collection chamber, the top side of dust collector box body to be equipped in the dust collector box body above high efficiency particulate air Gas outlet is offered, gas outlet connects collection chamber, is provided with valve on gas outlet, is provided on the plenum wall of gas outlet offside High pressure admission mouth, high pressure admission mouth connect high-pressure nozzle, and high-pressure nozzle connects high pressure tank, and high pressure tank is arranged in dedusting The top of device babinet is provided with impulse electromagnetic valve on high-pressure nozzle.
Specifically, the valve is electromagnetic valve.
Specifically, the outlet flue of flue gas input bottom of the tube is arranged in dust arrester.
Specifically, the dust collector box body is cylindrical box.
Specifically, it is provided with Venturi tube at the top of the flue gas input pipe.
Beneficial effects of the present invention are as follows:By the multiple of primary efficient filter screen, dedusting plate, dust-removal cloth-bag and high efficiency particulate air Filtering, improves the filter effect of flue gas, and dust removing effects are apparent, and the high pressure gas in high pressure tank is had frequency by impulse electromagnetic valve Rate, which must be blown into dust collector box body, carries out reverse gas cleaning, and the effect of deashing is more preferable, is conducive to environmental protection, good environmental protection.
