Abstract
The present invention provides an electrostatic precipitator, comprising an electrically charged unit and an electrostatic dust collection unit, and the electrostatic precipitator is characterized in that: the electrostatic dust collection unit adopts a spacer made from a metal material or an inorganic conductive material to keep a certain distance between dust collection plates and sheets. The air contact surface of the dust collection plates and sheets is made from an insulation material, so that adjacent dust collection plates and sheets may not be conducted. The spacer can be prepared by stamping molding of a metal plate such as an aluminum plate and a copper plate, also can be prepared by die-cast molding, metal bar pressing molding, and other manners, and an inorganic conductive material also can be used. Compared with a traditional electrostatic precipitator, electrostatic precipitator has the advantages of high efficiency, no arc discharge, low ozone and higher security.
Description
Technical field
The present invention relates to air purification field, particularly relate to a kind of precipitator.
Background technology
Traditional precipitator adopts metallic plate as control of dust material mostly, adopts the insulating materials such as plastics as spacer between metallic plate, to keep the spacing of each metallic plate and to increase dust arrester integral rigidity.The comparatively general way of spacer is the plastics card article of comb form, blocks each metallic plate on the one hand, on the other hand the spacing of each metallic plate is remained unchanged.
This mode technique is simple, but there is following outstanding problem:
1) between spacer and metallic plate, gap place certainly exists laying dust phenomenon, when there was dampness in the air, easily makes adjacent collecting plate form short circuit or acutely discharge;
2) after dust arrester cleaning, the easy Zang Shui in gap of spacer, thus cause short circuit, acutely discharge;
3) in actual use, the phenomenon that ubiquity spacer is even caught fire by scaling loss of discharging between plate.
Summary of the invention
The present invention is intended to propose a kind of new precipitator, to solve above-mentioned background technology Problems existing.
The technical solution adopted in the present invention is:
A kind of precipitator, comprises charge unit and electrostatic precipitation unit, it is characterized in that: the spacer that electrostatic precipitation unit adopts metal material or inorganic conductive material to make makes collecting plate, sheet keeps certain spacing.The surface contacted with air of collecting plate, sheet is insulating materials, thus makes adjacent collecting plate, sheet can not conducting.
Described spacer by metallic plate, as aluminium sheet, copper coin punch forming, also can adopt the mode such as die cast, bonding jumper pressing and forming.Also inorganic conductive material can be adopted.
Technological merit of the present invention is:
1) metal or inorganic conductive material is adopted to make the spacer of collecting plate, sheet, collecting plate, sheet surface are then coated with insulating materials, thus no matter there is moist dust the contact site of spacer and collecting plate, sheet or water residual after cleaning, and all electric discharge phenomena between plate can not occur;
2) adopt metal or inorganic conductive material to make spacer, its structural rigidity comparatively plastics tooth bar is better, and especially the forming method of metal spacer is various, is convenient to be formed on the whole airflow direction of control of dust sheet support constraint, ensure that better structural rigidity.So also make it possible to adopt thinner control of dust sheet, even can do camber, S shape, annular etc., the size of precipitator, shape and application scenarios are expanded greatly;
3) when metal spacer ground connection, certain electromagnetic shielding action can be played, thus reduce the electromagnetic radiation of precipitator;
4) surface that collecting plate, sheet contact with air is insulating materials, thus the spacing of collecting plate voltage that is less, that load can be made higher, thus the problem that conventional electrostatic dust arrester dust catching efficiency is low, generation ozone concentration is high, generation arcing cannot avoid Pi crack noise can be overcome.

Detailed description of the invention
Figure 1 shows that the typical structure of conventional electrostatic dust arrester collecting unit of dust, collecting plate 1 is metallic plate, and spacer 2 is the tooth bar of comb form, and material is ambroin, and spacer 2 is stuck between collecting plate, and each collecting plate is kept equidistantly.In order to avoid adjacent collecting plate discharges every sky, the distance between plates of collecting plate 1 is generally at 5-10mm.
As shown in Figure 2, be the structural representation of the electrostatic precipitation unit of a kind of embodiment of the present invention, collecting plate 3 Surface coating has insulating materials.Spacer 4 is metal material, and form as shown in Figure 3, has the wide strip slot of some 0.5mm on a metal plate for making collecting plate 3 pass and making each adjacent collecting plate keep 1.5mm equidistant.When loading high-voltage electrostatic power for collecting plate 3, can form strong control of dust electric field between collecting plate, dust laden air electric charge on grit band after charge unit, enters collecting unit of dust and can be attracted to collecting plate surface.Not puncture between adjacent collecting plate when distance between plates is enough little owing to this invention ensures that, acutely discharge, thus can have higher purification efficiency than traditional precipitator, actual measurement primary purification efficiency can reach 99.9% thus can substitute HEPA high efficiency particulate air completely.
