The utility model relates to an industrial dust removal equipment field especially is an electrostatic precipitator, beat the unit including casing, reposition of redundant personnel unit, a plurality of corona electrode, a plurality of anode plate, a plurality of water conservancy diversion electrode and pnematic shaking. The beneficial effects of the utility model reside in that, set up the water conservancy diversion electrode through the end subsiding the passageway for carry on one's shoulder or back electric dust because repulsion force that the water conservancy diversion electrode produced and with higher speed to the anode plate motion, make the anode plate can fully to catch the dust granule, through setting up the reposition of redundant personnel unit for the air of waiting to remove dust can fully evenly get into in each subsides the passageway, thereby ensures that each operating efficiency who subsides the passageway remains stable, ensures that whole dust remover has better dust collection efficiency, beat the unit through set up pnematic shaking on the diffuser plate for the deposition of reposition of redundant personnel on the unit need not additionally to provide under the driven condition the action of the wind down owing to shake that beat and the automation drops, the normal operating that keeps shunting the unit.

Description

A kind of electrostatic precipitator

Technical field

The present invention relates to industrial dedusting apparatus field, be especially a kind of electrostatic precipitator.

Background technology

Existing electrostatic precipitator, is to install cathode line in the casing of cleaner unit to coordinate group with enclosed positive plate The a plurality of sedimentation passage become, gas parallel cathode lines and positive plate pass through, and apply negative high voltage unidirectional current so that it is electricity in cathode line Producing negative particle from gas, flue dust is charged and adsorb on positive plate in flowing through way, is come off by rapping apparatus, thus reaches Remove the purpose of smoke particle in gas.But existing electrostatic precipitator has the disadvantage that flue dust can not in-plant against Positive plate flows through, and from charged to absorption, flue dust to flow through considerably long one section parabola distance, if positive plate is too short, it is just Trap less than flue dust, thus along with air-flow is discharged.Disadvantages described above makes electrostatic precipitator state emission standard to be reached Below 50mg/Nm3 difficulty is very big, according to widen, lengthen, the traditional means such as increasing puts into very big and effect and also pays no attention to Think, in practice it has proved that its effect is that local is with limited.Prior art additionally provides a kind of some by being symmetrical arranged at air inlet The flow deflector of differently curved degree makes flue dust have the initial velocity towards positive plate motion before entering sedimentation passage, so that Positive plate can fully capture charged flue dust, however the setting of above-mentioned flow deflector make to enter each sedimentation passage containing flue dust Different windages that air produces relative to air inlet angle difference due to flow deflector and skewness, so that part sedimentation is logical The flue dust flow in road is too high can not be the most charged, and too low this part that reduces of flue dust flow of remainder sedimentation passage settles The service efficiency of passage.

Summary of the invention

Present invention aim at solving the problems referred to above, it is provided that one can keep the higher operational efficiency of cleaner unit and charged The electrostatic precipitator that soot dust granule effectively can be caught by positive plate, is specifically realized by techniques below scheme:
