Compared with prior art, its detailed description is as follows: technical scheme provides a kind of blast furnace gas for the application
Dust arrester, described dust arrester includes the first cleaner unit being sequentially connected, the second cleaner unit, sets in described first cleaner unit
It is equipped with least 1 layer filter layer, described filter layer is vertical with airflow direction, is provided with vibration body before described filter layer, described
It is provided with least 1 layer adsorption layer, described adsorption layer is vertical with airflow direction in two cleaner units.By the first cleaner unit and the second dedusting
Device is combined, and arranges filter layer, the flue dust in blast furnace gas is got rid of big absolutely portion by filter type in the first cleaner unit
Point, the flue dust of removal is deposited to ash discharging hole by self gravitation, discharges outside cleaner unit.Clear for drainage screen in prior art
Clean, generally adopt anti-blowpipe, the dust on filter is carried out with injection cleaning, relatively costly by the way of anti-blowpipe, structure
Complexity, maintenance is inconvenient, and the setting of anti-blowpipe has certain resistance, present techniques side to the gas flow of blast furnace gas
In case, it is provided with vibration body before filter layer, when the dust accumulation on filter layer is to a certain extent it is impossible to free settling is to row
During grey mouth, the dust on filter layer can be departed from by vibration body, it is to avoid filter layer blocks and affects filter efficiency, resistance
Little, improve the service life of filter layer simultaneously.In technical scheme, it is provided with adsorption layer in the second cleaner unit, mainly
It is directed to the removal of acidic components in blast furnace gas, in prior art, acidic components are removed and typically adopt wet method to remove, wet method
Contain substantial amounts of vapor in gas after removal, need to carry out the removal of vapor again, equipment needed thereby is more more complicated, and this Shen
Acidic components please be removed using dry method in technical scheme, vapor will not be carried secretly, structure is simpler, effect more preferably, meanwhile, the
In two cleaner units, the lower section of adsorption layer is additionally provided with electrostatic precipitator, after removing remaining a small amount of flue dust, carries out acidic components
Removal, dedusting and purify effect more preferable.Therefore, technical scheme good dedusting effect, efficiency high, can go simultaneously
Except the acidic components in blast furnace gas, structure is simple, and convenient for installation and maintenance, device lifetime is long.
