Description
Technical field
The utility model relates to deduster technical field, particularly relates to a kind of pulsed jet cloth filter.
Background technology
Sack cleaner is a kind of dry type dust filtration device, and be generally made up of parts such as ash bucket, upper box, middle casing, lower boxes, upper, middle and lower casing is chamber structure.During work, dusty gas enters ash bucket by air inlet duct, and thick grit directly falls into hopper bottom, dustshot with air-flow turnover upwards enter in, upper box, dust is long-pending is attached to filter bag outer surface, and the gas after filtration enters upper box to pure qi (oxygen) concetrated pipe-exhausting duct, drains into air through exhaust blower.After filtrate uses a period of time, due to effects such as sieving, collision, delay, diffusion, electrostatic, one deck dust has been gathered on filter bag surface, 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.Therefore, after the resistance of deduster reaches certain numerical value, timely deashing.Current sack cleaner ash-removal effect is poor, and after using a period of time continuously, filter effect obviously reduces.
Utility model content
The utility model is in order to after overcoming sack cleaner of the prior art and using for a long time, the dust, dust etc. of filter bag outer surface are removed not exclusively, have a strong impact on the deficiency of subsequent filter effect, provide a kind of filter bag surface ash-removal effect good, the pulsed jet cloth filter of the good dust removing effects of filter bag can be kept.
To achieve these goals, the utility model adopts following technical scheme:
A kind of pulsed jet cloth filter, comprise cylindrical shell of dust remover, the lower end of shell of dust remover is provided with ash bucket, described shell of dust remover lower end outside is provided with air inlet pipe, shell of dust remover is provided with blast pipe outside upper end, dividing plate is provided with in described shell of dust remover, described dividing plate is separated into filter chamber the space in shell of dust remover, exhaust chamber, described blast pipe is communicated with exhaust chamber, described dividing plate is provided with some filter bag installing holes, a bag cage is separately installed with in each filter bag installing hole, the upper end of bag cage is fixedly connected with filter bag installing hole, the lower end of bag cage is stretched in filter chamber, in each bag of cage, correspondence is provided with filter bag, the upper end of filter bag is communicated with exhaust chamber, the upside of described dividing plate is provided with gas pipe, each filter bag inside is provided with the gas blow pipe stretched into bottom filter bag, the sidewall of described gas blow pipe is provided with some gas holes, the upper end of gas blow pipe is communicated with gas pipe, the pulse air accumulator be connected with gas pipe is also provided with outside described shell of dust remover upper end.
Dusty gas enters in filter chamber from air inlet pipe, dust accumulates in filter bag outer surface through filter bag, gas after filtration enters in exhaust chamber, discharge finally by blast pipe, along with gathering of filter bag outer surface dust, the filter efficiency of filter bag reduces, filter bag inside and outside differential pressure increases, now need to carry out deashing to filter bag surface, air inlet pipe closes air inlet, then pulse air accumulator action, produce high voltage pulse air-flow, air-flow enters in gas blow pipe, thus the dust of filter bag outer surface is blown off, dust finally drops on ash bucket, because gas blow pipe directly stretches into bottom filter bag, the air pulse of discharging from gas pipe is directly directed to bottom filter bag, effectively can remove the dust of filter bag lower end outside, filter capacity is recovered after filter bag ash removal, gas filtration can be carried out again.
As preferably, the surface of described filter bag is truncated cone-shaped structure, and the diameter of filter bag upper end is greater than the diameter of lower end; Described gas blow pipe and filter bag coaxially distribute, and the distribution density of gas hole reduces from gas blow pipe lower end gradually to upper end.When dust is gathered on filter bag surface, pressure reduction inside and outside filter bag can increase, and filter bag surface is the conical surface, and anti-pressure ability significantly improves, filter bag is not fragile, simultaneously due to the large footpath of filter bag upper, path under, therefore accumulate in the dust on filter bag surface early stage, can because follow-up air-flow be dropped to through out-of-date impact on ash bucket, when deashing, air pulse acts on filter bag, and dust departs from filter bag very soon and drops to hopper bottom, and deashing is more laborsaving.
As preferably, the bottom of described ash bucket is provided with ash discharging hole, and ash discharging hole place is provided with seal cover.When the dust that ash bucket inner accumulated is a large amount of, after needing to open seal cover, dust is discharged.
As preferably, be provided with flow guide sleeve in each filter bag installing hole, the both ends open of described flow guide sleeve is horn mouth, and the lower end of flow guide sleeve is fixedly connected with filter bag installing hole, described gas blow pipe, through flow guide sleeve, forms annular gap between gas blow pipe outer wall and flow guide sleeve inwall.During deashing, gas blow pipe is blown, and the air-flow that flow guide sleeve can reduce gas blow pipe blowout enters in exhaust chamber, thus makes more air flow energy act on filter bag, improves cleaning efficiency.
As preferably, the outside of described shell of dust remover is also provided with observation panel, and observation panel place is provided with transparent cover plate.Observation panel is convenient to observe the state in shell of dust remover, realizes visualized management, also can use as access hole simultaneously, overhaul convenient.
Therefore, it is good that the utility model has filter bag surface ash-removal effect, can keep the beneficial effect of the good dust removing effects of filter bag.
