Generally desulfurizing agent storehouse is arranged in coal transporting trestle；Air after conveying carbide slag is by being emitted into defeated coal after sack cleaner dedusting
Trestle.
But, due to containing moisture in the high temperature carbide slag that is typically transported, cleaner unit is condensed in into after desulfurizing agent storehouse
Cloth bag is pasted into dead on cloth bag, and carbide slag storehouse spalling caused by pressure is high in storehouse, along with conveyance conduit pressure height, and fill
There are the factors such as the discharge pressure height of tank car of limestone to combine, so as to easily cause problems with：
1st, the housing cracking of desulphurizer of boiler storehouse sack cleaner is easily caused, is deformed and is sprayed ash outward, it is defeated so as to cause
Coal belt porch stirs up a cloud of dust, 1 meter of insufficient visibility during most serious, or even whole each passageway to coal platform all diffuses carbide
Ground-slag, causes defeated coal personnel see the position of equipment clearly；
2nd, dust-collecting bag blocking is easily caused, and the service life of cloth bag is extremely low, often the new cloth bag changed can only make
Just scrapped with three days；
3rd, it is easily caused, and pressure conveyance conduit in high for conveying the conveying bleed pressure in the tank car of carbide slag
It is too high so that the conveying of carbide slag is extremely difficult；
4th, as cloth bag is blocked in desulfurizing agent storehouse, need to block up using vacuum release valve, easily cause the blast of desulfurizing agent storehouse, make
Obtain steel plate gross distortion, weld bond cracking and the support beam deformation in silo roof portion so that substantial amounts of agstone blows into boiler Factory Building, pot
A vast expanse of whiteness in stove Factory Building, must all wear anti-dust respirator, boiler plant area severe environmental pollution in central station of floating dock when serious.

Gas slag mixture in S101, desulfurizing agent storehouse 1 and in burner hearth 2 in mixing, the gas slag mixture in burner hearth 2
By the gas slag mixture desulfurization in desulfurizing agent storehouse 1.In other words, as the desulfurizing agent in desulfurizing agent storehouse 1 is in boiler
Material is carried out in once desulfurization, therefore the present embodiment, by the mixing that two kinds of gas slag mixture in the first pipeline occur, is gone back
The gas slag mixture in desulfurizing agent storehouse 1 can be caused to carry out secondary desulfuration effect to the gas slag mixture in burner hearth 2, so that after
Continuous dust removing effects are more preferably.
S2, by cleaner unit 3 be mixed gas slag mixture dedusting, to obtain the gas after dedusting.In the present embodiment,
Mixed gas slag mixture is further mixed in cleaner unit 3, and carries out dedusting by cleaner unit 3, will
Gas in gas slag mixture is separated with residue, and the residue after dedusting can be expelled directly out by cleaner unit 3.
S3, by the suction function of negative pressure unit by after dedusting gas discharge.In the present embodiment, the gas after dedusting by
After the gas outlet of cleaner unit 3 enters third channel, rapidly enter in chimney 8, then by chimney via the suction function of air-introduced machine 7
Exhaust outlet at the top of 8 is discharged, to avoid the gas after dedusting from directly coming in Factory Building, it is to avoid dust explosion and play occur in Factory Building
Strong pollution.
To sum up, the present embodiment in the device for the dedusting of desulfurizing agent storehouse, the afterbody of burner hearth 2 and desulfurizing agent storehouse 1 with
The air inlet connection of cleaner unit 3, the gas outlet of cleaner unit 3 are communicated with exhaust outlet by negative pressure unit, and negative pressure unit has negative pressure
Effect, after extracting out and mixing respectively from the gas slag mixture in desulfurizing agent storehouse 1 and in burner hearth 2, is removed by cleaner unit 3
Dirt, and when two kinds of gas slag mixture are mixed, moreover it is possible to desulfurization work is carried out, therefore, can by the device and dust collection method
The pressure release to station boiler desulfurizing agent storehouse 1, secondary desulfuration and dedusting work, and the process Environmental Safety are realized, is avoided that secondary
Pollution and the problem of dust explosion.
