Problems solved by technology

The electrostatic filter plate itself will absorb a lot of dust in the process of filtering air, but how to clean the filter plate has always been a technical problem that plagues the industry; if the gap between the filter plates is large, sometimes it is convenient to clean, but The filtering effect is reduced again
Patent No. CN202893510U discloses a dust collecting board; patent No. CN202336389U also discloses a similar technology, but does not completely solve the problem

Embodiment 1

[0032] Embodiment one, see figure 1 , image 3 and Figure 6 ,in image 3 It can also be a cross-sectional schematic diagram of other embodiments, the multi-stage parallel electrostatic air filter plate, from image 3 and Figure 6 It can be seen that it is composed of five parallel dust collecting plates 1, from figure 1 It can be seen that the dust collection plate 1 is composed of two metal plates 2 and the insulating electret material 3 wrapped outside it. The dust collection plate 1 is rectangular and sheet-shaped. The two metal plates 2 on the dust collection plate 1 One is connected to high potential, the other is connected to low potential, image 3 It can be seen that one side of the dust collecting plate 1 has two raised support points 5 of the same height, and the other side has a concave positioning groove 6 corresponding to each raised support point 5 .

Embodiment 2

[0033] Embodiment two, see figure 2 , image 3 and Figure 7 , the multistage parallel electrostatic air filter plate, from image 3 and Figure 7 It can be seen that it is composed of five parallel dust collecting plates 1, from figure 2 It can be seen from the figure that the dust collection plate 1 is composed of four metal plates 2 and the insulating electret material 3 wrapped outside it. The dust collection plate 1 is rectangular and sheet-shaped, and the number of metal plates on the dust collection plate is four. Among them, there are two metal plates 2 connected to high potential and two metal plates 2 connected to low potential, both of which are rectangles with the same size and shape. Two diagonally arranged metal plates 2 are connected to the same potential, and one surface of the dust collecting plate 1 has more than two raised support points 5 of the same height, and the other side has A concave positioning groove 6. in image 3 The two protruding suppo...

specific Embodiment 3

[0035] Specific embodiment three, such as Figure 14 As shown, the electrostatic air filter plate is composed of six dust-collecting plates 1, and each dust-collecting plate has a protruding part of a metal plate 2 at both ends, which is used to connect the positive or negative electrode, and has a protruding part at both ends. The support point 5 is combined with the concave positioning groove 6 of another piece to form an organic whole; the filter air passage is divided into multiple small filter air passages 8 by multiple sheets, Figure 13 It is a cross-sectional view of a single dust collection plate, from Figure 10 , Figure 11 , Figure 12 It can be seen that the sheet 7 can have various forms, Figure 10 It is Z-shaped, with a disconnection in the middle, and it can also be connected in practical applications; Figure 11 It is V-shaped; Figure 12 It is S-shaped. Of course, it can also present various other forms, such as W shape, straight shape and so on. From...

Abstract

The invention provides a multistage parallel static-electric air filtering plate which is composed of more than two dust collection plates in parallel, wherein the dust collection plate is composed of more than two metal plates and insulating electret materials coating the metal plates. The dust collection plate is rectangular sheet-like in shape. A metal plate connected to high electrode potential and a metal plate connected to low electrode potential are both disposed on each dust collection plate. There are more than two space static-electric fields formed in the direction being vertical to air channels, so that the air filtering plate can adsorb air particles under the multi-directional force of the multiple static-electric fields. The air filtering plate is better in effect and also is convenient to clean.

Description

technical field [0001] The invention relates to an electrostatic air filter plate, in particular to a multistage parallel electrostatic air filter plate. Background technique [0002] In the air that is constantly polluted in real life, fine particles, especially particles with a particle size less than or equal to 2.5 microns (PM2.5), cause great harm to human health; in order to improve the air in the living room or in the cab of a car, There are many devices that use the adsorption function of the electrostatic filter plate to achieve clean air. The electrostatic filter plate itself will absorb a lot of dust in the process of filtering air, but how to clean the filter plate has always been a technical problem that plagues the industry; if the gap between the filter plates is large, sometimes it is convenient to clean, but The filtering effect is reduced again. The patent of authorized announcement number CN202893510U discloses a kind of dust collecting board; The patent...
