Technical field
The present invention relates to the employed resin electrode of counter electrode of corona discharge electrode of the ionization source portion, duplicator, Destaticizing device, ozone generating-device etc. of electrostatic dust collect plant, the collecting electrode of the curren-collecting part of electrostatic dust collect plant, and the electrostatic dust collect plant that uses ionization source portion's counter electrode and curren-collecting part collecting electrode.
Background technology
For example, electrostatic dust collect plant makes electric charge on the dust lane in the air-flow by corona discharge etc., when this charged particle passes through in electric field, and caught and be removed, so the various types from industrial large-scale plant to home-use midget plant obtains using by electrostatic force.
On so electrostatic dust collect plant, usually aluminium, stainless steel and other metal materials are used to make electric charge on the dust particle band ionization source portion counter electrode and catch the collecting electrode of charged particle.
Such electrode constitutes, generally ionization source portion will be relative with corona discharge electrode to counter electrode be that intermediary arranges with the dividing plate, curren-collecting part also be the high voltage side electrode that similarly will apply positive potential or negative potential with relative with it to earth electrode alternately be the structure that intermediary is arranged in parallel with the dividing plate.
But when metallic plate was used for electrode, conductance was good, but had the weight of electrode itself to become heavy problem.
In addition, when metallic plate is used for electrode, need be that intermediary forms stackedly with the multi-disc metallic plate, so the numerous and diverse problem of assembling procedure is arranged with the dividing plate.
So, in order to simplify the assembling procedure of electrode, can consider, and, still the depth of pole plate can not be lengthened to more than the spacing between pole plate, so can not make large-area electrode with by integrally formed electrodes such as panel beating press process without the stacked structure of electrode.In addition, the zone that is made the particle neutral by the bending part of bending etc. and pass through is for example arranged, and the problem that causes dust collecting performance to descend.
In addition, the electrode of being made by metallic plate also exists the high problem of electrode, manufacturing cost that is difficult to make complicated shape.
In order to solve such problem, developed technology with resin manufacture electrode with electric conductivity.
As resin with electric conductivity, can be in resin as base material, for example suitably allocating into, the conductive material of carbon black, carbon fiber, conductive metal palpus crystalline substance and stainless steel fibre etc. obtains.
But, usually to get on very well at present, when allocating the carbon black as conductive material into, the words of not allocating in large quantities just can not obtain as the required low impedance value of counter electrode, and the words of allocating in a large number then make the intensity of resin descend significantly.And, generally be to adopt in ABS resin, to mix the resin electrode of making as the carbon fiber of conductive material.
