Description
Technical field
The utility model is related to a kind of bag filter Mars fire retardant devices more particularly to a kind of biomass boiler cloth bag to remove
Dirt device Mars fire retardant device, belongs to flue gas ash removal field.
Background technology
Currently, most common in the dust-extraction unit that the factories such as casting, metallurgical furnace body, biomass boiler use is exactly cloth-bag type
Deduster.Because dust and flue-gas temperature are very high, Mars is also carried, so being easy to burn out cloth after being directly entered fiber bag precipitator
Bag, and cloth bag not only labor intensive and time are replaced, and also maintenance cost is high, operation difficulty is big.Mars in flue gas is more made
It catches fire at deduster, severe patient makes factory's property cause damages, or even is damaged to personnel.
Also construction personnel develop bag filter Mars capture device come the dust and Mars in removing smoke, but
In actual use, not only containing the uncombusted Mars of bulky grain in flue dust, but also contain a small amount of uncombusted little particle fire
Star, these short grained Mars are easier to reach bag filter as air-flow passes over fire retardant device, it is easy to burn cloth bag
At duck eye, and causes concentration of emission not up to standard and influence cloth bag using effect.
On how to the dust and Mars in removing smoke, has related patents in the prior art and disclose, such as China is specially
Sharp notification number：CN104307300A, invention and created name are：Spark arrester, the device have the uncombusted Mars of bulky grain
It is certain to capture effect but helpless to the uncombusted Mars of little particle.
Invention content
The purpose of this utility model is exactly to overcome existing flue gas ash removal Mars to capture fire retardant device in actual operation
Mars capture effect is poor, cannot prevent the deficiency that molecule Mars enters bag filter completely, provide a kind of bag-type dust
Device Mars fire retardant device.
Bag filter Mars fire retardant device is made of two box parts in left and right, the areas A of two areas and the areas B above and below point,
Flue gas enters from the areas the A gas inlet end of left box body, by the cooling of flue gas coldplate, then the shock through baffling fire-proof plate, energy
Will bulky grain Mars collision after become smaller even extinguish, while speed reduce and under fall on the areas B, fall into the areas B ash bucket ash in gas
Dynamic Arch-Breaking Device effect it is lower by compressed air agitation at boiling fluidized state, be filled in the areas B area of space, can further by
A part of little particle Mars encirclement is put out.The Mars not eliminated is using first of metal micro-holes screen pack blocking in the areas B, pole
The fine particle Mars of small part stops by the areas A exhanst gas outlet second metal micro-holes screen pack, is thoroughly prevented with reaching
All Mars enter bag filter, and corresponding metal micro-holes screen pack is equipped with acoustic wave ash ejector or Air Force Blowing dust, to prevent micro-
Mesoporous metal mesh filter plate blocks.
