Compared with prior art, the utility model has the advantages that:
1) the dust removal combined structure of locellus of employing electric precipitation and bag-type dust satisfies service requirement under the different working conditions, and deashing is efficiently thorough; Prime electric precipitation efficiency of dust collection height is collected 80%~90% Dust Capacity; Back level bag-type dust is collected grain dust, guarantees the low concentration discharging.
2) the air inlet place is provided with airflow distribution device, and the dirt pocket internal gas flow is evenly distributed; Air-flow is distributed both guaranteed not reduce electric cleaner efficient, can satisfy sack cleaner again, prolonged life of bag filter the requirement that air-flow distributes;
3) Filter-bag carcass employing protective sleeve suitable for reading structure, the air-flow deflection that prevents to jet is washed away filter bag, for the organosilicon preservative treatment of skeleton, protect filter bag fully, prolongs life-span of the filter bag.
4) described jetting deashing system bottom is equipped with persuader, and it is far away to have jet length, and spray angle such as can control at characteristics; Make that deashing is thorough, drag losses is little, the winding-up bleed pressure is low, and energy consumption is low; The winding-up cycle is long, pulse width is narrow;
5), select the rational utmost point to join form, the efficient of the raising electric precipitation of employing sub-district power supply maximum possible and the security reliability of operation according to the dust characteristic.
6) running resistance is low, and life of bag filter is long, and energy consumption is little, and operation, maintenance cost is low.

The specific embodiment
See Fig. 1, Fig. 2, Fig. 3, a kind of efficient electric bag dust collector, the mode that this deduster adopts electric precipitation and bag-type dust to combine, cleaning efficiency height, long service life.The deduster air inlet connects the electric precipitation unit, and air outlet connects the bag-type dusting unit.Air inlet 1 place of electric precipitation unit is provided with airflow distribution device 2, sees Fig. 4, and airflow distribution device 2 is perforated plate constructions of evenly arranging.Electric precipitation unit housing 3 tops are provided with cathod system 4 and anode system 5, and the bottom is provided with ash bucket; Silicon rectifying transformer 18 is positioned at electric precipitation unit housings top.
In order to produce electric field, with anode system 5 ground connection, by silicon rectifying transformer 18 cathod system 4 (dust collecting electrode) is applied high voltage, irregularly shaped generation non-uniform electric field by negative electrode, make charged grit by its electrically charged not opposite polarity in the same way electrode movement separately, stressed and be captured at electric field.Grit after the capture is deposited on the dust collecting electrode (cathod system 4), and rapping apparatus 17 carries out rapping every some cycles to it, and the rapping power and the dust collecting electrode that produce by rapping apparatus break away from, and fall into the bottom ash bucket by the self gravitation sedimentation.
Then continue to move through flue gas and fine particle wherein after the electric field preliminary purification along the flow of flue gas direction, be folded to the electric field bottom at the electric field rear portion by deflector 6 (or 6 ') (two kinds of forms shown in Fig. 5-1, Fig. 5-2), the ventilating opening through the bottom enters the bagroom 10 of bag-type dusting unit.
