Abstract

The utility model relates to an electrostatic dust remover which can remove the dust in the air and can sterilize the bacteria in the air. The utility model is provided with a frame which is made of insulating material. The inner part of the frame is provided with a filter screen, and a corona wire and a metal cathode gating are respectively fixed on both side surfaces of the frame. The corona wire is connected with the anode of a high voltage generator, and the metal cathode grating is connected with the cathode of the high voltage generator. A strong electrostatic field is formed between the corona wire and the metal cathode gating in the frame. The utility model has the advantages reasonable structure and high dust removing effect; the bacteria on the filter screen can be killed, so the utility model has good dust collecting and sterilizing effect, and can raise the air purification degree.

Description

Electrostatic precipitator

The utility model relates to a kind ofly can be removed in the air dust and can kill the wherein device of bacterium, is a kind of electrostatic precipitator specifically.

Used air filter generally uses filter screen that dust in air is filtered out now.Microorganisms such as the bacterium in the dust can constantly breed on filter screen, also can cause secondary pollution, and it is healthy to have a strong impact on people; Useful anion purifier dedusting because of having electric charge on the dust, falls within around the dust arrester easily, and the dust arrester ambient contamination is strengthened.

The utility model purpose is to overcome the shortcoming in the above-mentioned technology, proposes a kind of electrostatic precipitator, it can be adsorbed in dust in the air on the screen pack fast, and can kill the bacterium that is attached on the dust, improves the air cleaning degree.

The utility model purpose is realized by following technical scheme: this electrostatic precipitator, the framework that has an insulating materials to make, filter screen is housed in the framework, it is characterized in that being fixed with corona wire and metallic cathode grid respectively in two sides of framework, corona wire is connected with the positive pole of high pressure generator, the metallic cathode grid are connected with the negative pole of high pressure generator, form strong electrostatic field between corona wire in framework and the metallic cathode grid, and filter screen is between corona wire and metallic cathode grid.

Corona wire be by conduct electricity very well, oxidation resistant molybdenum or tungsten wire be arranged in the plane along a parallel sided of framework, or weaves into netted plane, the diameter of corona wire is 0.01-2 millimeters.

The metallic cathode grid are the netted planes of being weaved into by copper or iron or stainless steel metal wire, and diameter wiry is 0.1-5 millimeters.Metallic cathode grid or by going out the porous plane that many apertures form on the metal forming, the thickness of metal forming is 0.01-1 millimeter.Scribble or be soaked with bactericide on the filter screen in the framework.

Because the voltage that high pressure generator produces later is very high, reaches 3-9 kilovolts, i.e. voltage difference between the negative pole plane that the positive polar plane of the formation of the corona wire in framework and metallic cathode grid form also reaches 3-9 kilovolts, forms very strong electrostatic field.Filter screen is in the very strong electrostatic field.When air is flowed through electrostatic precipitator, because a large amount of positive and negative electric charge that the high-voltage electrostatic field produces is attached on the dust.Under the effect of electric field force and wind-force, charged dust moves to the metallic cathode grid fast.Gathered by strainer filtering.Because of scribbling or be soaked with bactericide on the filter screen, the bacterium that can will accumulate on the filter screen kills.

The utility model advantage is that structure is more reasonable, because strong electrostatic field is arranged, has strengthened the detergent power that original single one physical is filtered, improved efficiency of dust collection, be filtered the dust bacterium on filter screen, can have been killed by bactericide, can better the control of dust sterilization, improve the air cleaning degree.

Embodiment of accompanying drawings:

Fig. 1 is a kind of electrostatic precipitator structural representation,

Fig. 2 is its cutaway view,

This electrostatic precipitator, the framework 2 that has an insulating materials to make is equipped with filter screen 5 in the framework 2, scribble bactericide 6 on the filter screen 5.Two sides at framework 2 are fixed with corona wire 3 and metallic cathode grid 4 respectively, and corona wire 3 is connected with the positive pole of high pressure generator 1, and metallic cathode grid 4 are connected with the negative pole of high pressure generator 1.High pressure generator 1 can produce 9 kilovoltages, forms strong electrostatic field between corona wire 3 in framework and the metallic cathode grid 4.Corona wire is that diameter is that 0.02 millimeter tungsten filament is arranged in parallel along the framework inboard, and the metallic cathode grid are that the copper wire of 0.2 millimeter of diameter is weaved into cellular net.
