Abstract
The utility model relates to an ash cleaning device of a pulse spraying duster of a bag type, comprising a catheter (4) and a nozzle (7), wherein, a site of the nozzle near the catheter (4) is symmetrically provided with side openings (8) which induce air to enter. Under the condition of same pulse spraying ranges, compared with the prior art, the utility model saves the quantity of compressed air by 20% more or less; when compressed air of the same quantity is consumed, compared with the prior art, the utility model increases the range by 25% more or less. The utility model is suitable for cleaning ash of a pulse spraying duster of a bag type with a filter bag having the length more than 6 meters.
Description
The utility model relates to the deashing device of industrial dedusting pulse blowing bag type dust precipitator, and particularly air-pressure duct goes out outlet structure.
Pulse blowing bag type dust precipitator is because of saving the energy, and the equipment operation management expense is low, good dedusting effect, efficient height, saving capital expenditure, plurality of advantages such as volume and floor space are little, development is very fast abroad, and the trend that replaces the chamber-dividing counter-blowing sack cleaner is arranged, and has also begun at home to use.Its weak point is to have only injection hole on the conduit that passes through of compressed air or add the short nozzle of straight tubular etc. on conduit.Because it is unreasonable to go out the outlet structure design, thereby compressed air consumption is big, range (the pulse jet air enters the effective impulse deashing distance in the filter bag) is short, and it is poor to cause filter bag bottom ash-removal effect long more than 6 meters, even can not deashing.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, improves the winding-up structure of the deashing device of pulse blowing bag type dust precipitator, to save the energy, strengthens the pulse jet range, also can obtain effective ash-removal effect for filter bag long more than 7 meters.
For achieving the above object, this programme be nozzle near the position symmetry of conduit offer induced air side mouth, in nozzle pulse jet in filter bag compressed-air actuated moment, but induced air come in, thereby improve the winding-up effect.
Inducing the side mouth can be two, three or more, symmetric arrangement, shape can be shapes such as round, oval, square or slit.
Test shows, when the pulse jet range is identical, saves compressed air consumption about 20% than prior art; When consuming identical air supply, can increase pulse jet effective range about 25% than prior art, its pulse jet effective range can reach about 9 meters, thereby more is applicable to effective deashing of the long filter bag more than 6 meters; And prior art not only the consumption of compressed air amount is big, and effective range is short.
Fig. 1 is the schematic diagram of pulse blowing bag type dust precipitator;
Fig. 2 is that node A is a nozzle organigram of the present utility model.
Among the figure, 1-deduster shell; The 2-pulse valve; 3-divides gas bag; The 4-conduit; The 5-filter bag;
6-cage bone; The 7-nozzle; 8-induces the side mouth;
Embodiment: conduit 4 and nozzle 7 all belong to deashing device, and conduit 4 and nozzle 7 can be one or 2 products.This novel improvements are exactly to offer the side mouth 8 that the induced air that all claims enters at nozzle 7 near the position of conduits 4.Can induce portion of air to come in nozzle 7 compressed-air actuated moment (0.1 second) of in the filter bag of hanging at upper face plate 15, jetting, with the effective range of saving compressed air consumption or increase pulse jet, thereby improve the ash-removal effect of filter bag long more than 6 meters or save compressed air consumption.
Claims (2)
1, the deashing device of pulse blowing bag type dust precipitator comprises conduit (4) and nozzle (7), it is characterized in that nozzle (7) offering the side mouth (8) that induced air enters near the position symmetry of conduit (4).
2, according to the said deashing device of claim 1, it is characterized in that said side mouth can be two, three or more; Its shape can be round, oval, square or slit.
