Abstract

The utility model discloses a cathode corona wire of an electrostatic precipitator for solving the problems that the cathode wire of the prior electrostatic precipitator has common strength distribution uniformity of electrical fields, easy wire friction and poor effects of vibration, ash removal and force transmission, the normal use of equipment is influenced, materials are wasted, and the like. In the utility model, a plurality of discharge bodies (1) are mutually parallel and are welded on the outer surface of a cathode rod (2) made of solid round steel, both discharge ends of each discharge body (1) are respectively arranged at both sides of the cathode rod (2), and therefore, the utility model has the advantages of uniform strength distribution of electrical fields, strong rigidity, wire friction resistance, good effects of vibration, ash removal and force transmission, reasonable selection and match of the discharge bodies indifferent lengths and structure modes according to different work conditions, and the like, and is favorable to the long-term high-efficiency operation of the electrostatic precipitator.

Description

The cathodic electricity hachure of electric cleaner

Technical field the utility model relates to a kind of cathod system of electric cleaner, particularly the cathodic electricity hachure of a kind of electric cleaner that is made of cathode rod, discharge body.

Technical background is present, the cathode line of disclosed electrostatic precipitator on the market, adopt line styles such as tubular barbed wire or helix mostly, its design feature is: the tubular barbed wire entity is a tubular structure, discharge body is welded on the both sides of pipe with certain spacing, adopt the utmost point of the corresponding positive plate of a tubular barbed wire to join form in the electric cleaner electric field, the electric-field intensity distribution uniformity that its prickle point discharge produced when electric field was connected high-tension electricity is general; Though the electric-field intensity distribution uniformity that the helix corona discharge produces is better and since its rigidity a little less than, have problems such as vibration dust-cleaning power transmission weak effect and broken string in actual use, the equipment that influences normally uses.

The summary of the invention the purpose of this utility model provides a kind of simple in structure, and the vibration dust-cleaning power transmission is effective, can improve the electric-field intensity distribution uniformity, eliminate the cathodic electricity hachure that breaks and save a kind of electric cleaner of steel consumption.

For achieving the above object, the cathodic electricity hachure of a kind of electric cleaner of the present utility model, constitute by cathode rod, discharge body, discharge body is arranged with a determining deviation and is arranged on the cathode rod, several discharge body are welded on the outer surface of the cathode rod of being made by the filled circles steel in parallel to each other, and discharge body two discharge ends are arranged in the both sides of cathode rod.

The discharge end of discharge body is processed into wedge shape prickle shape.

Several discharge body also can be connected on the both sides of the cathode rod outer surface of being made by the filled circles steel with certain spacing zigzag weld in parallel to each other.

Discharge body is processed into flat ring-type, and its major axis should be perpendicular to cathode rod, and is welded on the cathode rod.

After adopting this structure, in the electric cleaner electric field, can adopt the utmost point of the corresponding positive plate of two cathode line to join form, the electric-field intensity distribution uniformity that its flat ellipse discharge body point discharge produced when electric field was connected high-tension electricity improves, because the cathode line parent has adopted small dimension round steel and Welding Structure, make it not only have actual required rigidity but also can reduce material consumption, can keep enough vibration dust-cleaning power transmission effects in actual use and eliminate the broken string problem, help guaranteeing the long-term efficient operation of electric dust-removing equipment.And discharge end is by the cathode line of wedge shape prickle design, the extension elongation of discharge body prickle discharge end and the spacing between the adjacent discharge body can suitably be adjusted, for preceding electric field and the higher occasions such as smoke and dust treatment of dust concentration, choose the long and slightly little structure of spacing of prickle length, but enhanced discharge characteristic and anti-corona blocking ability; For back electric field and the little operating mode use occasion of dust concentration, choose the short slightly and bigger structure of spacing of prickle length, help improving field operation voltage, reduce the generation of problems such as current density and the anti-corona of elimination.

The utility model is described in further detail below in conjunction with drawings and Examples for description of drawings.

Among the figure: 1, discharge body; 2, cathode rod

The cathodic electricity hachure of specific embodiment Fig. 1 Fig. 2 Fig. 5 electric cleaner shown in Figure 6, constitute by cathode rod 2, discharge body 1, discharge body 1 is arranged with a determining deviation and is arranged on the cathode rod 2, several discharge body 1 are welded on the outer surface of the cathode rod of being made by the filled circles steel 2 in parallel to each other, and 1 liang of discharge end of discharge body is arranged in the both sides of cathode rod 2; The discharge end of Fig. 1 Fig. 2 Fig. 3 discharge body 1 shown in Figure 4 is processed into wedge shape prickle shape; Fig. 3 Fig. 4 Fig. 7 several discharge body 1 shown in Figure 8 also can be connected on the both sides of cathode rod 2 outer surfaces of being made by the filled circles steel with certain spacing zigzag weld in parallel to each other; Fig. 5 Fig. 6 Fig. 7 discharge body 1 shown in Figure 8 is processed into flat ring-type, and its major axis should be perpendicular to cathode rod 2, and is welded on the cathode rod 2.

When a kind of cathodic electricity hachure of deduster is in running order, the cathodic electricity hachure that is fixed on the cathode frame is relative with positive plate, after applying certain voltage, produce corona, make by dust therebetween chargedly, under the effect of the electric field force between cathodic electricity hachure and the positive plate, be captured then; Rapping power is by the cathode frame transmission, and acts on the cathode rod 2 by framework, and the vibration that makes the cathodic electricity hachure produce certain frequency realizes the purpose of vibration dust-cleaning.
