3, the combination of electric precipitation unit and bag-type dusting unit.Flue gas enters a bag dust removing units after by the electric precipitation unit.Flue gas directly do not enter a bag dust removing units, avoided flue dust to directly the washing away of filter bag, and life-span of the filter bag prolongs.Between electric precipitation unit and bag dust removing units, porous plate and flow-guiding channel are set, ash-laden gas by porous plate and flow-guiding channel after, can enter predetermined space according to a certain percentage, evenly carry and be assigned to each filter bag unit, do not influence efficiency of dust collection, running resistance reduces, and has avoided flue dust to wash away the damage filter bag, prolongs the service life of filter bag.Through repeatedly experiment, the ratio that the flue gas flow by both sides flow-guiding channel, porous plate and porous plate bottom accounts for total flow is controlled to be 15%, 15%, 30%, 40% respectively.
When dust-contained airflow enters into deduster, through the previous section electric precipitation, can remove most dust earlier, the dust of not removing mainly is a minuteness particle, and concentration is not high, at this moment passes through the bag-type dust unit again, can reach good dust removing effects.
For solving the problems of the technologies described above, the technical scheme that the utility model technical solution problem is adopted is:
Comprise electric cleaner, sack cleaner, a porous plate 11 is set between described electric cleaner and the bag collector, the both sides of porous plate are provided with flow-guiding channel 16.
The flue gas of the flow-guiding channel 16 of described both sides is controlled to be 15% respectively, is 40% from the flow-control of porous plate bottom, and the flue gas by porous plate is 30%.
Described deduster import department is provided with import loudspeaker 6, is equipped with two-layer in these import loudspeaker (6) or three layers of airflow-distribution board 5.
The beneficial effects of the utility model are, straight-through air inlet electricity-bag compound type dust remover effectively combines the advantage of two kinds of methods of tradition, minuteness particle efficiency of dust collection height, and deduster airflow resistance is little, and operation energy consumption is low, the filtering material long service life.

The specific embodiment
As depicted in figs. 1 and 2, the body of deduster is mainly by import loudspeaker 6, electric precipitation unit, bag-type dusting unit, and three parts are formed.Airflow-distribution board 5 is housed in the import loudspeaker.First module is the electric precipitation unit in two unit, mainly is made of corona wire 7, dust collector pole 15 plates, rapping apparatus 4, ash bucket 2 and incubator 10.Corona wire 7 is fixed in the cathode frame 9, is suspended on the insulation porcelain knob 8, and connects high-tension electricity, dust collector pole 15 plate earthings.When dust stratification acquires a certain degree, start rapping apparatus 4, carry out vibration dust-cleaning.Unit second is the bag-type dusting unit, mainly is made of filter bag and support frame 13 thereof, pulse valve 12, pulse tube 14.Filter type is an outside filtering type, arrives to a certain degree when ash is long-pending, and unbalanced pulse valve 12 carries out pulse dust cleaning.
After flue gas entered deduster, at first by import loudspeaker 6, under the effect of airflow-distribution board 5, air-flow distributed more even, enters the electric precipitation unit.Because corona wire 7 connects high-tension electricity, produces a large amount of electronics and anion, makes dust in flue gas charged, charged grit moves to dust collector pole 15 under the effect of electric field force, and is deposited on the dust collecting pole plate 15.Make grit fall into ash bucket 2 by rapping apparatus 4 vibration corona wires 7 and dust collector pole 15, reach the dedusting purpose.The electric precipitation unit carries out dedusting, and the electric precipitation unit has only an electric field, and dust-collecting efficiency is more than 70%, and remaining dust granules is thin, and is more higher relatively than resistance, collects relatively difficulty.This a part of dust electric field unit in front enters the pocket type unit that gathers dust through porous plate 11 and flow-guiding channel 16 after fully charged, because dust load is low and static reinforced effect, under the effect of filtering, dust deposit is on the surface of filter bag 13, when the pressure of filter bag 13 acquires a certain degree, rapid unbalanced pulse valve 12, compressed air is in abrupt release, in filter bag 13, spray, filter bag 13 outwards sharply expands therefore and rapidly, produce an impact shock, the dust on filter bag 13 surfaces falls into ash bucket 2 owing to inertia comes off from filter bag.Dust stratification in ash bucket 2 is discharged by unloading valve 1.
