Said rapping apparatus is fixed on crank on the transmission rapping shaft, and beater is connected with crank, and beater is realized vibration dust-cleaning through the transmission rapping shaft.
Said bag dedusting structure mainly comprises upper box, middle casing, blowing device, ash bucket and control system.
Said blowing device is installed in the upper box, in the middle casing filter bag is housed.
Said deduster body also comprises housing and ash bucket.
Said negative electrode row, anode row, rapping apparatus place the inside of deduster.
Said anode row is suspended on the girder that is fixed in the housing back timber, and said negative electrode row is suspended on the insulating sleeve of case top, and negative electrode row and anode row are staggered.
Adopt this programme beneficial effect: the electric-bag complex dust collector of the utility model; Its anode adopts sheath row; Sheath row's the pipe and the rounding off structure of framework square tube outer surface have been avoided point discharge phenomenon; Utmost point row's stability and thermal deformation resistant ability are strong, thereby have thoroughly stopped to dwindle the point discharge of generation because of distortion causes die opening; Its cathode line and negative electrode row's framework is a tubulose; The rounding off of its structure has been avoided point discharge phenomenon; Auxiliary electrode can be adjusted the intensity and the space electric field state of corona current, suppresses the generation of high resistivity dust back corona phenomenon, reduces the frequency of spray point point discharge; Additional simultaneously electric field force increases the migration velocity of dust, and dust-collecting efficiency improves; Its rapping apparatus adopts the tracking mode side rapping of floating, and recurrently takes off hammer, falls to hammer into shape phenomenon thereby stopped the board-like cottrell of common side arm sinker, and then overcome the therefore point discharge of generation.

The specific embodiment
To shown in Figure 8, the utility model electric-bag complex dust collector comprises the electric precipitation structure and bag dedusting structure two parts of installing front and back like Fig. 1; Said bag dedusting structure mainly comprises upper box 1, middle casing 2, blowing device 3, ash bucket and control system, and said blowing device 3 is installed in the upper box 1, in the middle casing 2 filter bag 4 is housed; Said electric precipitation structure mainly comprises deduster body and electrical system, and said deduster body mainly comprises negative electrode row 5, anode row 6, rapping apparatus 7, and said deduster body also comprises housing 8 and ash bucket 9; Said negative electrode row 5, anode row 6, rapping apparatus 7 place the inside of deduster; Said anode row's anode row is the pipe shape, and anode row's peripheral frame 12 is a square tube, and negative electrode row 5 cathode line and negative electrode row's peripheral frame is the pipe shape; Said anode row 6 is suspended on the girder 10 that is fixed in the housing back timber; Said negative electrode row is suspended on the insulating sleeve 11 of case top, and negative electrode row 5 and anode row 6 are staggered, and said negative electrode row and anode row's pipe shape is the rounding off structure; Anode adopts sheath row; Sheath row's the pipe and the rounding off structure of framework square tube outer surface have been avoided point discharge phenomenon, and utmost point row's stability and thermal deformation resistant ability are strong, thereby have thoroughly stopped to dwindle the point discharge of generation because of distortion causes die opening; Its cathode line and negative electrode row's framework is a tubulose; The rounding off of its structure has been avoided point discharge phenomenon; Auxiliary electrode can be adjusted the intensity and the space electric field state of corona current, suppresses the generation of high resistivity dust back corona phenomenon, reduces the frequency of spray point point discharge; Additional simultaneously electric field force increases the migration velocity of dust, and dust-collecting efficiency improves.
Said rapping apparatus 7 is fixed on crank 13 on the transmission rapping shaft 14; Beater 15 is connected with crank; Beater 15 is realized vibration dust-cleaning through transmission rapping shaft 14; The rapping apparatus tracking mode side rapping of adopt floating is recurrently taken off hammer, is fallen to hammer into shape phenomenon thereby stopped the board-like cottrell of common side arm sinker, and then overcome the therefore point discharge of generation.
The novel high-efficiency and energy-saving electric-bag complex dust collector is a kind of novel through the combination of electric precipitation and filter bag type dedusting, efficiently deduster.The prime electric precipitation utilizes ionisation of gas under high voltage electric field, dust and particle water obtain ion and charged, and under the effect of electric field force, move to the polarity opposite electrode, thereby are captured down.Because flue gas conditioning is good, the prime electric precipitation can effectively be removed the dust more than 80%.Sack cleaner is a kind of equipment that utilizes filtrate to capture suspension grit in the flue gas.Dusty gas is under the effect of negative-pressure air-flow, and the inlet entering deduster from separator gets into each element cell by mozzle; Under the effect of guiding device; Big dust particle directly falls into ash bucket after separating, and all the other dust evenly get into the filter bag in each bin filtering area with air-flow, when dusty gas passes filter bag; Dust promptly is attracted on the filter bag, and cleaned gas is discharged in filter bag.When reaching certain thickness, opens in the dust on being adsorbed on filter bag magnetic valve; The winding-up air gets into dust that filter bag will be adsorbed on the filter bag outside ash bucket below dropping down onto clearly with the rightabout of air scavenge from the filter bag exit from top to bottom, and dust utilizes ash-transmission system to see off after unloading valve is discharged.Add electric precipitation to the advantage of all kinds of dedusters on running resistance, electric-bag complex dust collector can be realized having complementary advantages technically.
