Problems solved by technology

[0003] The common feature of the above air purification technologies is that the filter membrane is used to capture particulate matter in the air. When the working time is long or the environment is harsh, the dust particles will quickly block the pores and the purification effect will decline.
[0004] There are also some high-voltage electrostatic dust removal methods to control particulate matter in the air (such as PM2.5), which are less efficient and produce harmful substances such as ozone
[0005] In recent years, plasma or net ion flow purifiers have been used abroad, which can effectively remove PM2.5, but the cost is high and it is difficult to popularize

no. 1 example

[0097] figure 1 It is a schematic diagram of an air purification method based on electrostatic deflection and an air purification device (single-channel flat plate type) according to the first embodiment of the present invention.

[0098] The main structure of the air purification device is a flat metal closed box, and the box lining material is, for example, mineral wool board and foam ceramic composite material, which play the role of heat insulation and air sealing. Corresponding positions at both ends of the box body are respectively provided with an air inlet and an air outlet. There are two pole plates 100, 200 fixed on the upper and lower inner surfaces of the box respectively in the box. The gap between the two polar plates 100, 200 is 10-200mm, and the size of the polar plates is 200*400mm. It should be noted that the gap between the plates can be adjusted as needed and matched with the electric field strength of the electrostatic field.

[0116] The third embodiment of the present invention is basically the same as the first embodiment of the present invention, the only difference is that the single-channel plate type of the first embodiment of the present invention is modified to the single-channel cylindrical type of the third embodiment of the present invention. For example, if image 3 As shown, the negative electrode plate 200 constitutes the inner cylinder of the air purification device, and the positive electrode plate 100 constitutes the outer cylinder of the air purification device, thereby forming an annular air channel between the negative electrode plate 200 and the positive electrode plate 100, thereby further improving the efficiency of air purification. efficiency. ...

Abstract

The invention relates to an air purification method and an air purification device based on electrostatic deflection. The air purification method based on electrostatic deflection comprises the following steps: spacing a positive plate and a negative plate by a certain distance and arranging oppositely, and applying a static electric field between the positive plate and negative plate, wherein the negative plate comprises a catalytic oxidation layer; enabling air to pass through the space between the positive plate and the negative plate so as to enable electrically charged particle matter in air to be deflected to the positive plate and the negative plate in an electrostatic way; carrying out catalytic oxidation on the electrically charged particle matter which are deflected to the catalytic oxidation layer of the negative plate in an electrostatic way. The air purification method and device based on electrostatic deflection, which are provided by the invention, have the beneficial effects that air can be purified efficiently at low cost without generating harmful substances of ozone and the like, are long-acting without maintenance, and especially can effectively remove PM2.5.

Description

technical field [0001] The present invention generally relates to an air purification method and an air purification device, in particular to an air purification method and an air purification device based on electrostatic deflection. Background technique [0002] With the aggravation of smog, the demand for air purifiers (especially air purifiers for PM2.5 control) has been increasing in recent years. At present, most air purifiers are filter type: the air is sent to the filter through the fan, and passes through various filter screens with different functions to achieve the effect of filtering out coarse, medium and fine particles; further, it has physical capture And filter with chemical decomposition function: mineral crystal film, photocatalyst decomposition film, HEPA film and so on. [0003] The common feature of the above air purification technologies is to use filter membranes to capture particulate matter in the air. When the working hours are long or the environm...
