Description
Technical field
The utility model relates to bag-type dusting deashing device structural design and the applied technical field in dust removal device in flue gas, and a kind of pressure-fired combination deashing device is provided especially.
Background technology
At present, all kinds of sack cleaners is widely used in the industry-by-industries such as electric power, metallurgy, chemical industry.Its operation principle is basic identical: endways under the attraction of air-introduced machine, produce negative pressure, under the effect of negative pressure, dusty gas enters the former flue gas air chamber of deduster by dust shield through pipeline, passing through dedusting filtering bag, grit is delayed at outer (or interior) surface of filter bag, forms gradually dust layer, gas after filtration enters air-purifying chamber, by pipeline through chimney discharged to atmosphere.Along with the prolongation of running time of equipment, be attached to the staubosphere progressive additive of filter bag, the resistance of deduster can increase, and now needs to carry out deashing work.All kinds of sack cleaners are different, and the main distinction is in its ash removal method.
Sack cleaner purge mode mainly contains air-flow reverse gas cleaning and pulse jetting deashing at present:
As shown in Figure 3, air-flow reverse gas cleaning, it is main being generally chamber-dividing counter-blowing deashing, a deduster is divided into several chambers, during deashing, utilize and close pure qi (oxygen) outlet, open the entrance of blowback air-flow, back blowing machine work makes blowback air enter filter bag through blowback pipeline, blowback air-flow blows to filter bag outer surface from filter bag inside, and the staubosphere of filter bag outer surface is come off.This purge mode deashing pressure is lower, is generally less than 0.003-0.01Mpa, in deashing process filter bag distortion little, approach staticly, life-span of the filter bag is longer, but is not suitable for tough flue dust, range of application is subject to certain limitation.
Deashing is rushed in pulse spray, generally that compression pressure is greater than 0.3Mpa, at the time that the is less than 2 seconds filter bag of jetting at a high speed, make filter bag produce from inside to outside the pulse vibration of expanding, filter bag outer surface obtains very large acceleration, thereby shake off surperficial staubosphere, this purge mode, ash-removal effect is fine, but deashing air pressure is larger, in deashing process, back and forth distortion is larger for filter bag, and life-span of the filter bag is shorter.
People urgently wish to obtain the good pressure-fired combination deashing device of a kind of technique effect.
