The utility model provides an electrostatic dust removal module, which can increase the contact area between the air flow and the electrode plate, and improve the purification effect.

In the embodiment of the present utility model, as shown in Figures 1 to 4, the electrostatic precipitator module includes a housing 100 and a plurality of dust removal units disposed in the housing 100, any of the dust removal units includes an ionization assembly and The dust collection assembly, the ionization assembly is used to ionize the airflow to be purified and make it charged; the dust collection assembly is correspondingly arranged on the air outlet side of the ionization assembly, and the dust collection assembly includes a collecting pole 200 and The repeller 300 , the repeller 300 and the collector 200 are arranged obliquely along the thickness direction of the casing 100 .

Since the collecting pole 200 and the repelling pole 300 are inclined along the thickness direction of the dust removal unit, the length of the dust removal channel in the dust removal unit of a certain thickness is longer, so that the area of the dust removal channel can be increased, thereby improving the electrostatic dust collection. The purification effect of the device; on the other hand, under the premise of a certain length of the dust removal channel, the oblique dust removal channel occupies a smaller size along the thickness direction of the dust removal unit, which is conducive to the miniaturization of the electrostatic precipitator module.

It should be noted here that the dust removal channel refers to the space between the collector 200 and the rejector 300; the inclined arrangement of the rejector 300 and the collector 200 along the thickness direction of the housing 100 refers to the axis of the dust removal channel There is an included angle between the perpendicular to the air inlet surface and the air outlet surface.

In one embodiment of this patent, the inclination angle of the dust removal channel ranges from 10° to 45°. The larger the inclination angle, the smaller the thickness occupied by the dust removal channel per unit length. The length of the dust removal channel of a dust removal unit with a certain thickness The longer; but when the inclination angle is too large, because the angle between the air inlet of the dust removal channel and the inflow direction of the air to be purified is too large, the friction between the air to be purified and the dust removal channel during the inflow of the air to be purified is large, and the noise generated larger. Experiments have shown that when the inclination angle is 20°, the electrostatic precipitator module has a good purification effect and low noise; when the inclination angle is 45°, the electrostatic precipitator module has the best purification effect; when the inclination angle is 10°, the electrostatic precipitator Module noise is minimal.

The structure of the dust removal channel of this patent is now further described with reference to FIG. 4 . In this embodiment, the repellers 300 are arranged in parallel between two adjacent collectors 200 .

As a preferred manner, the repeller 300 is located in the middle of two adjacent collectors 200 to form two dust removal channels with equal cross-sectional sizes. The cross-sections of the dust-removing channels are equal in size, so the bias electric fields of the same size can be generated in the two sub-dust-removing channels, so that the amount of dust adsorbed on different collectors 200 is approximately equal, so that the cleaning of the collectors 200 can be facilitated.

Specifically, the ionization assembly and the collection assembly of the existing electrostatic precipitator module are sequentially arranged at intervals in the flow direction of the gas. In this way, a gap is formed between the excitation electrode 400 and the collector electrode 200, resulting in a large size of the ionization unit. To reduce the volume of the electrostatic precipitator module, in this embodiment, the two excitation electrodes 400 and the two collector electrodes 200 are integrally formed one-to-one.

Please refer to Fig. 3, in one embodiment of this patent, in order to increase the dust removal capacity of the electrostatic precipitator module, the dust removal units are provided side by side along the first direction, and the first direction is the same as the flow direction of the airflow to be purified. (The direction of the arrow in Fig. 3) is vertical, since there are multiple dust removal units, the area of the adsorption channel is larger, and since there are multiple dust collection units, the adsorption area of the dust collection unit can be increased, and the static electricity can be improved. The dust removal capacity of the dust removal module.

In the above-mentioned embodiments of this patent, in order to further increase the dust-absorbing area of the dust-collecting pole and further improve the dust-collecting effect of the electrostatic precipitator module, the dust-collecting pole is arranged in a corrugated shape, and the dust-collecting pole arranged in a corrugated shape has The larger surface area, thus, improves the dust collection capacity of the electrostatic precipitator module.

Considering that there is a high-voltage ionization process in the process of ionizing the dust particles by the ionization electrode 500, ozone will be generated during the high-voltage ionization process, in order to reduce the ozone and prevent the ozone from affecting the health of users, in an embodiment of this patent, the surface of the repelling electrode 300 is coated Covered with an ozone reducing substance layer.
