Abstract
The utility model discloses an electrostatic dust remover, comprising a case body, a power unit, a dust collection rolling barrel, a discharging assembly, an insulating barrier and a corona. The power unit is installed on the case body. The inside of the case body is provided with the dust collection rolling barrel and the discharging assembly which are connected with the output end of the power unit. The insulating barrier and the corona of a discharging terminal are installed in the middle area of the dust collection rolling barrel in axial direction. The insulating barrier on the corona divides the discharging terminal into a plurality of regions and blocks the direct contact of dust-containing airflow and the discharging terminal. As a consequence, the insulating barrier can effectively prevent the discharging terminal from being covered by ash, which raises the cleaning efficiency largely.
Description
Affiliated field:
The utility model relates to a kind of corona discharge that utilizes and captures dust, to purify the electrostatic precipitator of dirty flue gas or air.
Background technology:
Remove dust in the dirty gas with electrostatic precipitator, be to utilize to be arranged on the corona in the electrostatic precipitator and to make its discharge, allow and form an inhomogeneous field between corona and the dust collecting electric plate, when pending dirty gas flows through this electric field, make the dust of gas Zhong charged, force these charged particles to be adsorbed on the opposite polarity dust collecting electric plate, to realize passing through electrostatic precipitation.
As, the name of No. 1091659 bulletins of Chinese patent is called a technology of " electrostatic precipitator " and has just utilized above-mentioned principle.This kind electrostatic precipitator has adopted to be had dust passive electrode, the emitting stage how row be arranged in parallel and connects first and second adjusting device at interval, with the first interval adjusting device, every package draw together a plurality of rectangle dust passive electrodes mutually arranged side by side by predetermined fixed distance in every row be provided with toward each other so that their surface is vertical; With the second interval adjusting device, a plurality of rectangle emitter stages of every row are fixed in every row by preset distance, be provided with also toward each other so that their surface is vertical, there is the zigzag part at two edges of each emitter stage.Alternately arrange between dust passive electrode and the emitter stage, utilize dirty gas to flow through dust passive electrode sheet abreast, make in the inhomogeneous field of dust particle between emitter stage and dust passive electrode charged, be adsorbed onto then on the dust passive electrode sheet positive electricity level, thereby reach the purpose that purifies dirty gas.But, owing to all being arranged in respectively at interval at a certain distance by a plurality of sheet metals, the dust passive electrode of this electrostatic precipitator and emitter stage form on the adjusting device, its manufacturing process is cumbersome, and behind the full dust that falls on the dust passive electrode group, by vibration dust passive electrode group the dust of having collected is come off, easily cause cleaned gas to be polluted once more, clean-up effect reduces relatively simultaneously; Another problem is, cleaned gas directly contacts with emitter stage in purification process, and the dust in the gas very easily overlays on the emitter stage, particularly particle opposite polarity with it can be adsorbed on the emitter stage, cause it can not produce predetermined electric-field intensity, do not reach desirable dust removing effects.
In addition, CN1264623A has also announced technology that name is called " a kind of electrostatic precipitator ", the structure of this deduster be by metal cylinder and communicate with it have air inlet pipe and ash releasing tube and by the flue-dust retainer of stent support, and the corona wire, insulation vibrator and the power-supply device that are installed in the metal cylinder are formed.The negative pole of this deduster high voltage source is connected by insulator, lead and corona wire, constitute the high voltage electric field loop, when gas in air inlet pipe enters metal cylinder during formed high voltage electric field, dust particle is filled negative electrical charge with, and be attracted on the positively charged metal cylinder, and the gas after being cleaned flows out from the top of metal cylinder, and the effect of the adsorbed dust of metal cylinder by vibrator makes it enter ash releasing tube and discharge.Though this deduster structure is simple, the deduster of this structure is subjected to its structural limitations, is difficult for handling a large amount of dirty gas, and by the dust on the vibrator rapping metal barrel, dust is flown upward, also easy cleaned gas in the pollution metal tube for the second time; Simultaneously, all are overall structures because corona and metal cylinder adopt, the discharge terminal of corona equally also is easy to touch dust, and then influences its discharge effect, and collected dust is also inhomogeneous on the metal cylinder.
Summary of the invention:
