Description

Tri-electrode formula electric cleaner

Technical field

The utility model relates to a kind of fume dust remover, particularly a kind of tri-electrode formula electric cleaner.

Background technology

At present, general Elex precipitator is the negative pressure operation, but can not control, regulate; In addition, control of dust pole plate (anode) is all made with sheet metal.Corona discharge electrode (negative electrode) is then formed with circle silk or prickle shape.So be referred to as printed line template formula electric cleaner.Printed line template formula electric cleaner is in service to exist many drawbacks: negative pressure can not be adjusted to optimum state, and the soot dust granule movement velocity that causes thus is too fast, then can cause efficiency of dust collection and reduce; The template dust collecting electrode is at high temperature yielding, thereby changes die opening; Die opening is excessive, and it is too small to play corona current, and electric-field intensity weakens catches the dirt ability drop, and die opening is too small, and it is excessive to play corona current, causes flashover (sparking), punctures pole plate, causes damage; The very two-sided corrosion of template control of dust, the life-span is short, and overhaul cost increases; Template dust collecting electrode dust-collecting area is little, and as the big dust-collecting area of need, then equipment volume increases, and rolled steel dosage increases, and expense is also huge thereupon to be increased; Electrical equipment control falls behind, and operator's labour intensity is big, and the reason difficulty is looked in maintenance, and the overhaul life is short, the maintenance cost height.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of simple in structure, the tri-electrode formula electric cleaner that efficiency of dust collection is high.

For achieving the above object, the technical solution adopted in the utility model is: comprise the housing that offers air inlet and air outlet, in housing, be disposed with the dust removing units that has anode row, negative electrode row and ash bucket more than two groups along air inlet, be characterized in, on the crossbeam of each dust removing units upper end, also be provided with pressure regulator valve, the anode row who is arranged in the dust removing units is tubular structure and is fixed on equably on the crossbeam of housing that the negative electrode row who is arranged in the dust removing units is made up of interlaced equally distributed tubulose auxiliary cathode and herring-bone form corona electrode.

Another characteristics of the present utility model are: pressure regulator valve comprises the taper insulator on the crossbeam that is arranged on housing, be provided with supported flange and adjustment disk in the upper end of taper insulator, correspondence offers through hole on supported flange and the adjustment disk, and also is provided with the suspension rod that is used for fixing dust removing units in the taper insulator; Be respectively arranged with vibration body on every row's anode row and the negative electrode row, vibration body comprises the beater that is hinged on anode row and negative electrode row side and runs through anode row and negative electrode row's rotating shaft composition that position corresponding with beater on rotating shaft also is provided with fork.

Because anode row of the present utility model and negative electrode row all adopt tubular structure, make dust-collecting area increase, its efficiency of dust collection is greatly improved, and has only an outer surface to be corroded, can increase by two times service life and save a large amount of maintenance costs, tubular structure distortion is little under hot environment, thereby electric field is stable, moves smooth and easy, more avoided striking off the phenomenon of corona discharge electrode, owing to be provided with pressure regulator valve, negative pressure can be regulated, so can under the regulation negative pressure, move by assurance equipment.

The specific embodiment

Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.

Referring to Fig. 1, the utility model comprises the housing 5 that offers air inlet 1 and air outlet 6, in housing 5, be disposed with three groups and have anode row 3 along air inlet 1, the dust removing units 15 of negative electrode row 13 and ash bucket 7, on the crossbeam 8 of each dust removing units 15 upper end, also be provided with pressure regulator valve 4, the anodes row 3 who is arranged in the dust removing units 15 is made up of anode tube on tubular structure and the crossbeam 8 that be fixed on housing 5 equably, the negative electrodes row 13 who is arranged in the dust removing units 15 is made up of interlaced equally distributed tubulose auxiliary cathode 16 and herring-bone form corona electrode 14, and arranges on 13 at every row's anode row 3 and negative electrode and to be respectively arranged with vibration body 2.

Referring to Fig. 2, vibration body 2 of the present utility model comprises that being hinged on anode row 3 and negative electrode arranges the beater 18 of 13 sides and run through anode row 3 respectively and negative electrode row 13 rotating shaft 19 is formed, and position corresponding with beater on rotating shaft 19 also is provided with fork 20.

Referring to Fig. 3,4, pressure regulator valve 4 of the present utility model comprises the taper insulator 12 on the crossbeam 8 that is arranged on housing 5, be provided with supported flange 9 and adjustment disk 10 in the upper end of taper insulator 12, correspondence offers through hole 17 on supported flange 9 and the adjustment disk 10, and also is provided with the suspension rod 11 that is used for fixing dust removing units 15 in taper insulator 12.

The course of work of the present utility model is as follows: when anode row 3 and negative electrode row 13 connect 50KV～70KV high-voltage DC power supply respectively, formed a powerful electromagnetic field in the passage between anode row 3 and the negative electrode row 13, because having adopted three-pole is anode tube, auxiliary cathode 16 and herring-bone form corona electrode 14, thereby form a two-region electric field that constantly repeats, when band cloud of dust gas enters electric field, grit is ionized, electronegative grit anode is raftinged moving, positively charged grit is to auxiliary cathode 16 motions, when electronegative grit is arranged on 2 attached to anode, begin discharge, energy falls in the ash bucket 7 through vibration body 2 rappings after discharging, and positively charged grit is then most of attached on the auxiliary cathode 16, thereby alleviated the burden of corona electrode 14, prevented the generation of corona clogging.

For the operating vacuum magnitude of energy conditioning equipment, the utility model is installed in the adjusting of the adjustment disk 10 realization negative pressure on the taper insulator 12 by adjusting, when negative pressure is excessive, rotation adjustment disk 10 makes the through hole 17 on the adjustment disk 10 be connected with through hole 17 on the flange 9, otherwise, then rotate adjustment disk 10 and make through hole 17 and the through hole 17 on the flange 9 on the adjustment disk 10 stagger promptly closed.

Vibration body 2 of the present utility model drives fork 20 rotations by the rotating shaft 19 that runs through anode row 3 and negative electrode row 13, fork 20 lifts beater 18 in rotation, when forwarding certain angle to, fork 20 on the rotating shaft 19 is thrown off with beater 18, beater 18 is heavy impacting on anode row 3 and negative electrode row 13 falling under the gravity effect, makes grit fall into ash bucket 7.
