Description
Technical field
The utility model relates to steam power plant's ash disposal field, particularly a kind of blowback bellows transmission device, exhaust dust device with bag and electric bag dust arrester.
Background technology
As shown in Figure 1, sack cleaner is a kind of dry type dust filtration device, after filtrate uses a period of time, due to effects such as sieving, collision, delay, sack cleaner diffusion, electrostatic, one deck dust has been gathered on filter bag surface, and this layer of dust is called bonding layer, in motion process after this, bonding layer has become the main filtration layer of filtrate, and rely on the effect of bonding layer, the filtrate that mesh is larger also can obtain higher filter efficiency.Along with dust gathering at filter material surface, efficiency and the resistance of deduster increase all accordingly, when the pressure differential of filtrate both sides is very large, some can be attached to the tiny grit extruding past on filtrate, dust collector efficiency is declined.In addition, the too high meeting of resistance of deduster makes the air quantity of dust pelletizing system significantly decline, and therefore, after the resistance of deduster reaches certain numerical value, timely deashing, can not destroy bonding layer during deashing, in order to avoid efficiency declines.
Electric bag compound type dust remover (being also electrostatic fabric filter) is the feature having organically combined electrostatic precipitation and bag-type dust, by a kind of high-efficiency dust remover of the gathering dust in advance of prime electric field, charged effect and rear class filter bag district dust removal by filtration, it gives full play to electric cleaner and sack cleaner dedusting advantage separately, and both combine and produce new feature performance benefit, compensate for the dedusting shortcoming of electric cleaner and sack cleaner.It is high that this complex type dust remover has efficiency, and stable, resistance of the filter bag is low, life-span is long, the advantages such as floor space is little, be the following technical way controlling the multi-pollutant associated treatment such as fine particle dust, PM2.5 and heavy metal Hg, the technical characterstic of electrostatic fabric filter is as follows:
Dust removal mechanism: due in electric bag compound type dust remover, flue gas is first by slowly entering rear class bag-type dust district again behind electric precipitation district, and the Dust Capacity of bag-type dust district trapping only has 1/4 of entrance.The dust load amount of such filter bag reduces greatly, and cleaning cycle is significantly extended; Dust is charged through the ionization of electric precipitation district, the charged of dust improves the filtering feature of dust on filter bag, namely the permeability of filter bag, deashing property aspect are much improved, reasonable utilization electric cleaner and sack cleaner dedusting advantage separately, and both combine and produce new function, fully can overcome the dedusting shortcoming of electric precipitation and bag-type dust, according to current experimental study and the commercial Application at electric boiler flue dust, prove that this technology is a kind of science, reliable, advanced technology.Combine the advantage of two kinds of dedusting methods; Ensure that long-term efficient stable runs: the efficiency of dust collection of electric bag compound type dust remover does not affect by coal, flue gas characteristic, fly ash resistivity, can keep efficient, stable for a long time, reliably run, ensure that concentration of emission is lower than 30mg/Nm3; Running resistance is low, filter bag ash removal is long for cycle time, there is energy-saving effect, the dust load amount of electric bag compound type dust remover filter bag is little, adds the effect of dust charge electrical effect, and therefore the resistance of dust layer to air-flow of filter bag formation is little, be easy to deashing, the running resistance of 500Pa more than lower than conventional sack cleaner, the cleaning cycle time is conventional sack cleaner 4-10 times, greatly reduces the operation energy consumption of equipment; Life of bag filter is long: because the filter bag ash removal cycle extends greatly, so deashing number of times reduces, and filter bag dust gas permeability is strong, resistance is low, and the intensity load of filter bag is little, thus extends life of bag filter; Run, maintenance cost be low: electric bag compound type dust remover by service life of reducing filter bag quantity in right amount, extending filter bag, reduce running resistance, extend operation, maintenance cost that the approach such as cleaning cycle reduce deduster greatly.
As described in Fig. 2 or 3, the branch chamber back-blowing bag type dust collector of existing a kind of blowback air port reciprocally movement, relate to a kind of sack cleaner, in order to solve the deashing mechanism of existing sack cleaner without realizing by room deashing mouth to mouth, ash-removal effect is poor, complex structure, the problem such as to break down, and technical essential is: the anti-deashing device of described locellus is arranged in air-purifying chamber, one end of Telescopic type reverse blower connects deashing source of the gas and introduces reverse gas cleaning air-flow, and the other end connects moving back blowing mouth; Described transmission mechanism tethered sliding formula blowback air port and Telescopic type reverse blower move back and forth, and move to described little air-purifying chamber outlet successively, to carry out by the mouth-to-mouth orientation blowback deashing in room.
But when pulling the transmission device broken strand of steel cable of blowback bellows movement, above prior art all can not change the steel wire rope of disconnected stock very easily, causing and being forced to blowing out and just can carrying out more change steel rope.
