The bag-type dust catcher can solve the problems in the prior art that speed on a smoke inlet is too high, air current distribution is uneven, and secondary dusting is caused by dust particles in the ash bucket.
Description
Technical field
The utility model belongs to the flue gas ash removal field, particularly relates to a kind of sack cleaner that is used for the iron and steel metallurgical industry high temperature fume dust removal.
Background technology
At present, the pollutant emission standard mainly carried out of steel industry mainly contain " industrial furnace atmosphere pollutants emission standards " (GB9078-1996), " coke oven atmosphere pollutants emission standards " (GB16171-1996).Along with the variation of the fast development of China's steel and iron industry and structural adjustment in recent years and production pattern, existing discharge standard has lagged far behind the progress of technical development, can't adapt to 21 century steel and iron industry environmental protection requirement under the new situation.It is 30～50mg/m that State Environmental Protection Administration requires in " the steel and iron industry pollutant emission standard " of new establishment the highest permission concentration of emission of particle
3
China Steel industry particle dust discharge amount was 107.3 ten thousand tons in 2007, accounted for 15% of national dust discharge amount.The sack cleaner of iron and steel metallurgical industry use at present mostly is middle part flue ash bucket air inlet structure form, this version makes that smoke inlet speed is too high, the air-flow skewness, and cause dust granules reentrainment of dust in the ash bucket, to all having a strong impact in sack cleaner service life and dust removing effects.The task of requiring the cleaner reform task that the flue dust qualified discharge brings, new reorganization and expansion to the application of novel sack cleaner provide for a long time, reliable market.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of novel sack cleaner that is used for the iron and steel metallurgical industry high temperature fume dust removal, too high with smoke inlet speed in the solution prior art, the air-flow skewness causes the problem of dust granules reentrainment of dust in the ash bucket.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of sack cleaner that is used for the iron and steel metallurgical industry high temperature fume dust removal is provided.By the air inlet ash bucket, inlet channel, the exhaust passage, air intake valve, drain tap, on take off cover plate, the winding-up gas bag, the row winding-up, gas bag air feed source of the gas and pneumatic operated valve air feed source of the gas are formed, described air inlet ash bucket is equipped with the double-deck flap valve of weight, described inlet channel, the exhaust passage lays respectively at deduster body both sides, described air intake valve is loaded in the inlet channel, described drain tap is loaded in the exhaust passage, described winding-up gas bag is a bivalve pattern gas bag side by side, be positioned at dust remover roof, described winding-up gas bag uses gas bag air feed source of the gas, described air intake valve, drain tap uses pneumatic operated valve air feed source of the gas.
Described air inlet ash bucket, inlet channel, exhaust passage, air inlet operated pneumatic valve, exhaust operated pneumatic valve, on take off unit that cover plate, winding-up gas bag, row winding-up, gas bag air feed source of the gas and pneumatic operated valve air feed source of the gas form can be single or at least two and be unified into deduster.
Beneficial effect
The utility model is arranged in the side of deduster with the flue gas inlet channel, has avoided smoke inlet speed too high, the air-flow problem of uneven distribution; Simultaneously, use the double-deck flap valve of weight and side by side dual valve type gas bag structure make automatic ash-discharging more effective; Gas bag, pneumatic operated valve adopt gas circuit and air accumulator separately, and independent generation of each system influences each other, and system stable operation, increase service life.Below all improved the whole dust removing effects of clarifying smoke system, made the soot emissions requirement that is up to state standards.

Wherein: 1-air inlet ash bucket, 2-inlet channel, 3-exhaust passage, 4-air inlet operated pneumatic valve, 5-exhaust operated pneumatic valve is taken off cover plate on the 6-, the 7-gas bag of jetting, the capable winding-up of 8-, 9-gas bag air feed source of the gas, 10-pneumatic operated valve air feed source of the gas, 11-bag-type dust district, the 12-smoke inlet, 13-exhanst gas outlet, 14-compressed air.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
A kind of sack cleaner that is used for the iron and steel metallurgical industry high temperature fume dust removal, comprise air inlet ash bucket 1, inlet channel 2, exhaust passage 3, air intake valve 4, drain tap 5, on take off cover plate 6, winding-up gas bag 7, row winding-up 8, gas bag air feed source of the gas 9 and pneumatic operated valve air feed source of the gas 10, described air inlet ash bucket 1 is equipped with the double-deck flap valve of weight, described inlet channel 2, exhaust passage 3 lays respectively at deduster body both sides, described air intake valve 4 is loaded in the inlet channel 2, described drain tap 5 is loaded in the exhaust passage 3, described winding-up gas bag 7 is bivalve pattern gas bags side by side, be positioned at dust remover roof, described winding-up gas bag 7 uses gas bag air feed source of the gas 9, described air intake valve 4, drain tap 5 uses pneumatic operated valve air feed source of the gas 10.Described air inlet ash bucket 1, inlet channel 2, exhaust passage 3, air inlet operated pneumatic valve 4, exhaust operated pneumatic valve 5, on take off unit that cover plate 6, winding-up gas bag 7, row winding-up 8, gas bag air feed source of the gas 9 and pneumatic operated valve air feed source of the gas 10 form can be single or at least two and be unified into deduster.
As Fig. 1, Fig. 2, Fig. 3, during work, ash-laden gas enters air inlet ash bucket 1 by smoke inlet 12, big dust particle is because effects such as inertial collision, natural subsidence directly fall into air inlet ash bucket 1, all the other dust are crossed inlet channel 2 with air communication and are entered bag-type dust district 11 and filter, and the clean gas after the filtration 3 is discharged from the exhaust passage.The dust that accumulates in the air inlet ash bucket 1 is realized automatic ash-discharging by the double-deck flap valve of weight; The dust that accumulates in bag-type dust district 11 is by winding-up gas bag 7 gas jet, forms air wave, comes off thereby make filter bag produce rapid expansion and impact shock.
