The corona electrode device adopting the structure can avoid the phenomenon that the short circuit between the anode and the cathode damages a power supply, and has the advantages of low production cost, long service life and good purification treatment effect.
Description
The utility model relates to a kind of electrode assembly of high-pressure electrostatic discharge, especially a kind of corona discharge assembly of removing miniature impurity in the air-flow.
In the electric cleaner, particularly cooking fume control equipment, the oil flue waste gas that often adopts high-voltage electrostatic dust separator to come treatment and purification dusty gas or kitchen to produce, and the corona electrode device is the critical component of high-voltage electrostatic dust separator.At present, the corona electrode device of extensive use in cooking fume control equipment is a kind of corona electrode device of wire, this corona electrode device, it comprises perpendicular to some of airflow direction positive electrode plates uniformly-spaced parallel to each other, at least the negative electricity polar filament of a tension on the median plane between every adjacent two positive electrode plates is fixed their two ends with an insulating support between positive electrode plate and the negative electricity polar filament.When the logical high voltage of positive electrode plate and negative electrode wire connection, corona discharge takes place around the negative electricity polar filament, air in the electric field is ionized, produce a large amount of negative ions, wherein cation is under powerful negative electricity polar filament electric field action, be attracted to negative electrode very soon and neutralize, anion and free electron are then towards the control of dust face migration of positive electrode plate.When dusty gas or oil flue waste gas during, negative electrical charge on dust, mist of oil particulate and the anion collision belt, under electric field action, move to the control of dust face of positive electrode plate, and be attracted on the control of dust face by this electric field; And near positive charge on the elaioleucite in the oil flue waste gas of negative electricity polar filament and the unneutralized cation collision belt still, be attracted to very soon on the negative electricity polar filament.Because the negative electricity polar filament is when corona discharge, temperature is very high, is drawn to the elaioleucite decomposes carbonization of negative electricity polar filament, forms C, CO and H
2O discharges with air-flow, thereby oil flue waste gas is purified.
Yet, the negative electricity polar filament is when work, place's condition of high temperature, it constantly contacts the generation chemical reaction and suffers erosion with waste gas, inhomogeneous spot appears in reduced cross-sectional or surface, and intensity decreases is in case rupture when work, will cause the contact short circuit with positive electrode plate, high-pressure generating circuit will be burnt; Negative electrode adopts tungsten filament or molybdenum filament usually in addition, and cost is very high.
At the problems referred to above, the purpose of this utility model provides that a kind of production cost is low, long service life, corona electrode device reliably.
Corona electrode device of the present utility model has an anodal framework, several its two ends uniformly-spaced parallel to each other respectively with anodal framework on the fixing positive plate of relative two deckle boards, described each positive plate is electrically connected mutually; On the median plane position between two whenever adjacent positive plates, has a negative electrode at least, the two ends of this negative electrode are contactlessly protruding from the set through hole of relative two deckle boards of anodal framework respectively, the external part of negative electrode is fixed on the negative pole framework that anodal framework is peripheral with anodal frame insulation is connected, and described each negative electrode is electrically connected mutually; Described negative electrode adopts its cross section to be " V " shape isosceles structure, and its plane of symmetry overlaps with the median plane of adjacent two positive plates, and each described " V " shape isosceles electrode is arranged in the same way.
Corona electrode device of the present utility model, owing to adopted the negative electrode of its cross section for " V " shape isosceles structure, its rigidity and fastness significantly improve, and " V " shape openend of electrode point is prominent, linearity is good along its length, can guarantee to have between electrode uniform and stable, the linear bloom district that intensity is bigger, the negative electrode in " V " shape isosceles cross section has automatic minute wind energy power in electric field simultaneously, can effectively the oil flue waste gas branch be delivered to by the control of dust face of positive plate, thereby can make the oil smoke gas that enters electric field accept the effect of high energy particle in the electric field comprehensively, make smoke gas purification more thorough; The region of discharge of " V " shape isosceles negative electrode is only on " V " openend, even open end high temperature and thermal chemical reaction suffer erosion when work, but it is very little to the overall mechanical strength influence of negative electrode, thereby both avoided the short circuit between positive and negative electrode and damaged high pressure generation power supply phenomenon, prolonged the useful life of this device again, clean also very conveniently, maintenance cost is economized; These " V " shape isosceles structure electrodes can be made with materials such as the metal material of cheapness such as A3 steel, brass, stainless steels in addition, and cost greatly reduces.
Concrete structure of the present utility model is provided by the following drawings.
Fig. 1 is the structural representation of the utility model corona electrode device.
Fig. 2 be Fig. 1 along A-A to cutaway view.
Fig. 3 is the enlarged drawing at I place among Fig. 2.
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the corona electrode device has an anodal framework 1, this positive pole framework contains relative two strip electrodes disconnected from each other 3,8, deckle board is generally made with metallic plate, several are parallel to each other uniformly-spaced arrange its two ends respectively with the fixing positive plate 4 of deckle board 3 and deckle board 8,6, positive plate adopts aluminum alloy materials to make, and each positive plate is electrically connected mutually; At every two adjacent positive plates 4, there are five negative electrodes 5 with same intervals median plane position between 6, referring to Fig. 3, negative electrode adopts the isosceles structure of its cross section for " V " shape, its available inexpensive metal material such as A3 steel, brass bending form, and the median plane of its plane of symmetry and adjacent two positive plates 4,6 overlaps, two Tiaokou lines 13,14 of " thereby V " isosceles structure negative electrode opening part become point discharge place of negative electricity plate 5, to obtain bigger discharging current.This two Tiaokous line 13,14 is parallel to adjacent positive plate 4,6, and has and adjacent two spacings that positive plate is identical, thereby can guarantee that uniform and stable linear bloom district is arranged between electrode.The head 15 of " V " shape isosceles structure negative electrode points to the mouth 12 that facings the wind of work in the same way, has convection cell and divides the wind effect automatically, oil flue waste gas effectively can be delivered to the control of dust face of positive plate and be handled.For reducing windage, the head 15 of " V " shape isosceles electrode is an arc-shaped transition.As shown in Figure 1, the two ends of negative electrode 5 are contactlessly protruding from the set through hole of relative two deckle boards of anodal framework 13,8 respectively, and external part is fixed on the negative pole framework 2 of anodal framework periphery.The end of all negative electrodes is electrically connected.With four high-frequency ceramic insulators 7,9,10,11 they are fused between anodal framework 1 and the negative pole framework 2.
