Description
Technical field
The utility model relates to technical field of dust removal equipment, relates to a kind of pulsed dust-removing device specifically.
Background technology
At present, the operation principle of pulsed dust-removing device is as follows: dusty gas enters filter chamber by ash silo, and comparatively coarse granule directly falls into ash silo, and dusty gas is through sock filtration, and dust detention is shown in bag, and pure qi (oxygen) enters into air-purifying chamber through filter bag micropore, is discharged in air by blower fan.Dust when filter bag surface constantly increases, when causing equipment resistance to rise to setting value, differential pressure controller will output signal, and program control instrument is started working, unbalanced pulse valve one by one, make compressed air carry out blowing-out ash by spout to filter bag, filter bag is expanded suddenly, under the effect of inertia, the dust investing bag surface departs from filter bag and falls into ash silo, dust is discharged by ash-discharging device, and after whole filter-bag blowing deashing terminates, deduster is resumed work.The method of this deashing, by jet in filter bag, filter bag is expanded suddenly, and make the dust investing filter bag surface hightail the effect that filter bag reaches deashing, in actual production, this effect to air blast deashing in filter bag is also bad, because filter bag is also operationally under being in barotropic state, filter bag itself is also expand, then to the inside air blast, the space that filter bag expands is very little, dust, under the effect of inertia, still keeps static, is attached to filter bag surface, and this air blast suddenly, also very large to filter bag damage.Therefore, need to develop a kind of pulsed dust-removing device, gas in filter bag can be released, the original filter bag expanded is shunk suddenly, the space that so filter bag runs will become large, and dust just more easily departs from filter bag surface and falls, and the effect of deashing can be better, and also little to filter bag damage, be conducive to the service life of improving filter bag.
Utility model content
The purpose of this utility model is to provide a kind of pulsed dust-removing device, gas in filter bag can be released, the original filter bag expanded is shunk suddenly, the space that filter bag is run becomes large, dust just more easily hightails filter bag surface and falls, the effect of deashing can be better, and also little to filter bag damage, is conducive to the service life of improving filter bag.
The purpose of this utility model is achieved in that and comprises lower bracket, filter chamber, ash silo, ash-discharging device, filter bag, exhaust outlet, total gas approach, pulser, electric control system, is evenly equipped with some filter bags in filter chamber, pulser is arranged on the position that the side of filter chamber and ash silo join, and pulser comprises air inlet set storehouse, intake valve, a cylinder, air inlet air-breathing conversion storehouse, muffler, suction fan, suckback valve, back suction gas storehouse, No. two cylinders, air inlet set storehouse, air inlet air-breathing conversion storehouse, back suction gas storehouse is connected successively by dividing plate, air inlet set storehouse bottom baffles is provided with intake valve, intake valve is by connector and a cylinders, the bottom baffles in air inlet air-breathing conversion storehouse is provided with suckback valve, suckback valve is by connector and No. two cylinders, ash silo side is provided with ash silo air inlet, air inlet air-breathing conversion storehouse is connected with ash silo air inlet, air inlet set storehouse is connected with total gas approach, the import of suction fan is connected with back suction gas storehouse, and its outlet is connected with total gas approach by muffler.
The utility model is outside filter chamber and ash silo junction has installed air inlet set storehouse successively, air inlet air-breathing changes storehouse, back suction gas storehouse, and respectively air inlet set storehouse and air inlet air-breathing conversion storehouse bottom baffles on be provided with intake valve and suckback valve, by controlling the switch of intake valve and suckback valve, achieve the switching of pulsed dust-removing device filter bag ash removal and normal dedusting work.During dust arrester dedusting, open intake valve, close inlet valve, ash-laden gas just enters in filter bag from air inlet concetrated pipe by ash silo air inlet, when filter bag needs deashing, opens inlet valve, close intake valve, taken away by gas in filter bag by suction fan, under the effect of back suction power, the dust investing bag surface hightails filter bag and falls into ash silo and the object reaching deashing.Gas in filter bag is taken away owing to have employed suction fan by the utility model, filter bag is made to produce reverse suction, the amplitude of filter bag motion strengthens, the better effects if of deashing, and due to this back suction power be that the filter bag that originally expanded is shunk, also little to the damage of filter bag, be conducive to the service life of improving filter bag.
