Abstract
The utility model discloses a pulsed single deduster which comprises an air bag, blowing pipes, an induced draft fan, a motor, filter bags, a dust hopper, a gravity discharge valve, an air inlet pipeline, a filtering chamber, a pulse valve and a box body, wherein the gravity discharge valve is arranged at the bottom of the ash hopper, the filter bags are arranged in the filtering chamber and include longitudinal filter bags and horizontal filter bags which are longitudinally and horizontally connected, the blowing pipes are arranged above the filter bags, the pulse valve is arranged between the blowing pipes and the air bag, and the induced draft fan is arranged at the upper end of the box body. The horizontal filter bags are arranged above the longitudinal filter bags, each filter bag corresponds to one air outlet, online ash cleaning can be realized, the dedusting effect is strong, and the pulsed single deduster is applicable to various waste gases containing various dust contents; the gravity discharge valve is arranged at the bottom of the ash hopper, so that the pulsed single deduster has the advantage of being convenient for dust discharge.
Description
Technical field
The utility model relates to a kind of pulsed stand-alone deduster.
Background technology
Along with the development of modern industry, dust is on the rise to the pollution of environment, administers the pollution of dust, the purification mankind's living environment has become compatriots' common recognition.Clean in order to safeguard production environment, cleaning is by the place of dust pollution in time.Deduster can be widely used in clearing up polishing machine, automobile, motorcycle, Spring Industry mill spring machine, chemical industry, cement building material, timber processing, grain processing, pharmacy, machining energy industry.But the deduster volume using is at present large, installation cost is high, and moisture easily soaks cloth bag, affects removing dust and clearing ash effect, and it is comparatively difficult to unload ash.As far back as the early 1980s (before introducing U.S. Fuller technology), a large amount of investigation has been carried out in the local dirt source in domestic each cement plant, and the existing problem of unit dedusting unit that domestic cement industry is used is studied.The unit dedusting unit of the models such as HD, PL, LLC, LY, FCL/D, LD is located to adopt in the top, storehouse in many cement plants, belt feeder reloading point, bottom of the reservior etc., these unit main features are that volume is little, unit volume processing air quantity is large, filtration velocity is high, compact conformation, but be suitable for cement industry, do not process high concentration dust-laden exhaust gas, deashing mechanism fault rate is high.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of online ash removal, cheap, dust removing effects is strong, applicable various dustiness waste gas, and unload dirt pulsed stand-alone deduster easily.
For addressing the above problem, the utility model adopts following technical scheme: a kind of pulsed stand-alone deduster, comprise airbag, injection tube, air-introduced machine, motor, filter bag, flue-dust retainer, gravity dumping valve, intake stack, filter chamber, pulse valve and casing, described gravity dumping valve is arranged at flue-dust retainer bottom, described filter bag is arranged in filter chamber, longitudinal filter bag that described filter bag is set to connect in length and breadth and laterally filter bag, described injection tube is arranged at filter bag top, described pulse valve is arranged between injection tube and airbag, and described air-introduced machine is arranged at casing upper end.
As preferably, described air-introduced machine is connected with motor, is provided with more than one venthole in described injection tube, and described each venthole is all over against a longitudinal filter bag.
As preferably, described horizontal filter bag is arranged on longitudinal filter bag top, and described filter bag is terylene needled felt.
The beneficial effects of the utility model are: owing to being longitudinally provided with horizontal filter bag above filter bag, the corresponding venthole of each filter bag, can online ash removal, and dust removing effects is strong, applicable various dustiness waste gas; In flue-dust retainer bottom, be provided with gravity dumping valve, there is the dirt of unloading advantage easily.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of pulsed stand-alone deduster of the utility model.
The specific embodiment
Consult shown in Fig. 1, the utility model adopts following technical scheme: a kind of pulsed stand-alone deduster, comprise airbag 1, injection tube 2, air-introduced machine 3, motor 4, filter bag 5, flue-dust retainer 6, gravity dumping valve 7, intake stack 8, filter chamber 9, pulse valve 10 and casing 11, described gravity dumping valve 7 is arranged at flue-dust retainer 6 bottoms, described filter bag 5 is arranged in filter chamber 9, longitudinal filter bag (not shown) that described filter bag 5 is set to connect in length and breadth and laterally filter bag (not shown), described injection tube 2 is arranged at filter bag 5 tops, described pulse valve 10 is arranged between injection tube 2 and airbag 1, described air-introduced machine 3 is arranged at casing 11 upper ends.
Described air-introduced machine 3 is connected with motor 4, in described injection tube 2, be provided with more than one venthole (not shown), described each venthole is all over against a longitudinal filter bag, and described horizontal filter bag is arranged on longitudinal filter bag top, and described filter bag 5 is terylene needled felt.
Dusty gas enters flue-dust retainer 6 by intake stack 8, and then dusty gas enters the filter chamber 9 that filter bag 5 is housed.Dust is attached to filter bag 5 outer surfaces, and Purge gas enters upper box body 11 by filter bag 5, through exhaust duct, by air-introduced machine 3, is discharged in atmosphere.With the increase of filtration time, the dust that filter bag 5 outer surfaces adhere to constantly increases, and filter bag 5 resistances rise thereupon, when dust remover resistance rises to a setting value, for guaranteeing that deduster works on, need to carry out deashing.During deashing, deashing controller sends instruction, makes pulse valve 10 go out compressed air in the abrupt release of action.Compressed air pours at a high speed filter bag 5 by the venthole over against filter bag 5 in injection tube 2, when it pours filter bag 5 inside, induction produces one and is several times as much as compressed-air actuated " chain induction air-flow " again, so produce a kind of moment impact ripple and propagate downwards along the length direction of whole piece filter bag.Utilize this mechanism, make the dust that accumulates in filter bag 5 outsides from filter bag 5 wall exfoliations, dust falls into flue-dust retainer.The duration of pulse can be adjusted, to be applicable to the various characteristics of different dusts.When the dust in flue-dust retainer 6 reaches some, gravity dumping valve 7 can automatically be opened dust is drawn off.
Pulsed stand-alone deduster of the present utility model can online ash removal, and dust removing effects is strong, applicable various dustiness waste gas, and there is the dirt of unloading advantage easily.
The above, be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
