The purpose of this utility model is achieved through the following technical solutions: a kind of prickle iris type electrode humidifying electrostatic precipitator, comprise the metal dust collector pole of cylindrical tube, the bottom of metal dust collector pole has the air inlet of round platform tubulose, and top has the air outlet of round platform tubulose; Have two relative the first manholes in the upper end of metal dust collector pole, have two relative the second manholes in the lower end of metal dust collector pole, the axis of described two the first manholes and the axis parallel of two the second manholes; The inwall of the metal dust collector pole between the first manhole and the second manhole welds some parallel metal partion (metp)s, and described metal partion (metp) is circular protrusion structure; Between the second manhole and air inlet, have the 3rd manhole, the water smoke output channel of humidifier is fixedly connected with metal dust collector pole through the 3rd manhole.
The ceramic insulator of tubulose is all fixedly connected with the second manhole place at the first manhole; Be provided with metal discharge pole in the inside of metal dust collector pole, described metal discharge pole is the I-shape construction be welded by three metal solid circular pipes; Two ends and the following two ends of top, metal discharge pole are each passed through ceramic insulator, and are fixedly connected with ceramic insulator.
The vertical edge of metal discharge pole is positioned on the axis of cylindrical tube metal dust collector pole; On the vertical edge of metal discharge pole, the position corresponding with adjacent two metal partion (metp) centre positions is equipped with four symmetrical metal prickles, and described metal prickle is conical structure, and axis is vertical with the vertical edge of metal discharge pole; Weld metal dust collector pole power pins on the outer wall of metal dust collector pole.
The beneficial effects of the utility model are:
1, dust collector pole shape is changed.Add the metal partion (metp) of circular protrusion at tubulose dust collector pole inwall, its material is the metal identical with dust collector pole.By mating of the projection of this metal partion (metp) and the projection of discharge electrode metal prickle, not only increase field intensity, and expand stroke field intensity area territory scope, thus improve dust catching efficiency.
2, humidifier is added at tunnel inlet place.By this device, dust granules is combined with the atomization globule, improve dust in charged efficiency of following control of dust stage and improve dust catching efficiency.Make this deduster also have humidification function simultaneously.
3, discharge electrode shape is changed.The metal prickle of identical material is added on columniform discharge electrode surface.Due to the effect of point discharge, around this metal prickle, produce corona, greatly strengthen electric-field intensity near it, not only reduce the magnitude of voltage required for electric discharge, saved the energy of input, and improve the efficiency making dust granules charged.
4, pipeline adopts vertical structure.In the dust granules of porch humidification and the common aggegation of the globule on metal dust collector pole, it is made not easily to produce airborne dust.In addition, vertical structure makes water droplet along pipeline landing together with dust, and can collect in below, thus serves the effect of metal dust collector pole automated cleaning.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of prickle iris type of the utility model electrode humidifying electrostatic precipitator, comprise the metal dust collector pole 9 of cylindrical tube, the bottom of metal dust collector pole 9 has the air inlet 1 of round platform tubulose, and top has the air outlet 8 of round platform tubulose; Have two relative the first manholes in the upper end of metal dust collector pole 9, have two relative the second manholes in the lower end of metal dust collector pole 9, the axis of described two the first manholes and the axis parallel of two the second manholes; The inwall of the metal dust collector pole 9 between the first manhole and the second manhole welds some parallel metal partion (metp)s 4, described metal partion (metp) 4 is circular protrusion structure; Between the second manhole and air inlet 1, have the 3rd manhole, the water smoke output channel of humidifier 2 is fixedly connected with metal dust collector pole 9 through the 3rd manhole.
The ceramic insulator 7 of tubulose is all fixedly connected with the second manhole place at the first manhole; Be provided with metal discharge pole 6 in the inside of metal dust collector pole 9, described metal discharge pole 6 is the I-shape constructions be welded by three metal solid circular pipes; Two ends and the following two ends of top, metal discharge pole 6 are each passed through ceramic insulator 7, and are fixedly connected with ceramic insulator 7, and metal discharge pole 6 and metal dust collector pole 9 are insulated.
The vertical edge of metal discharge pole 6 is positioned on the axis of cylindrical tube metal dust collector pole 9, on the vertical edge of metal discharge pole 6, the position corresponding with adjacent two metal partion (metp) 4 centre positions is equipped with four symmetrical metal prickles 5, as shown in Figure 2, described metal prickle 5 is conical structure, and axis is vertical with the vertical edge of metal discharge pole 6; Weld metal dust collector pole power pins 3 on the outer wall of metal dust collector pole 9.
The course of work of the present utility model is as follows: operationally, and the part that metal discharge pole 6 is exposed in external environment is connected to high voltage source negative pole, and metal dust collector pole power pins 3 is connected to high-voltage power cathode, and humidifier 2 is energized.Wind is caused air inlet 1 by extraneous blower fan, and open humidifier 2 and high voltage source, deduster is started working.After air-flow enters air inlet 1, the globule aggegation that humidifier 2 produces is on dust.After being entered dedusting region by the air-flow after humidification, metal discharge pole 6 and metal prickle 5 electric discharge make air ionization, produce a large amount of anion, make and negative electrical charge on the dust lane of globule aggegation, the dust of the electronegative and globule, under the electric field action of metal prickle 5 and metal partion (metp) 4, is collected on metal dust collector pole 9.Metal partion (metp) 4 strengthens electric field strength and serves the effect upsetting the flowing of internal gas flow normal straight, makes air-flow produce ring-shaped convection, slow down air-flow velocity, increase the chance that in air-flow, dust contacts with metal dust collector pole 9, improve efficiency of dust collection.Meanwhile, because the existence of the moisture film that the globule is aggregated on metal dust collector pole 9, reentrainment of dust can not be produced.Meanwhile, on metal dust collector pole 9 condensation water stay along the inwall of metal dust collector pole 9, take away the dust that inwall is collected, play self-cleaning effect, avoid the adverse effect of dust to electric field simultaneously.Air-flow after dedusting flows out from air outlet 8.
