[0033] Please refer to Figures 1 to 3 The utility model embodiment provides a kind of electrostatic precipitator (not shown in figure), for dust removal to air, improve the cleanliness of air.The electrode sheet 100 has higher structural strength, is not easy to deform, can effectively improve the stability of air duct spacing, ensure ionization effect, to enhance electrostatic precipitation effect.

[0034] The electrostatic precipitator includes base (not shown in figure) and multiple electrode sheets 100. Among them, multiple electrode sheets 100 are all installed on base, base is used to fix and limit multiple electrode sheets 100, multiple electrode sheets 100 are spaced apart along its thickness direction, and air duct is formed between adjacent two electrode sheets 100, for dust-containing gas to blow through.

[0035] Specifically, the plurality of electrode sheets 100 comprises a plurality of high-voltage electrode sheets and a plurality of low-voltage electrode sheets, wherein the plurality of high-voltage electrode sheets and the plurality of low-voltage electrode sheets are arranged alternately in sequence, and a wind channel is formed between adjacent high-voltage electrode sheets and low-voltage electrode sheets. Since a high-voltage electric field can be generated between adjacent high-voltage electrode sheets and low-voltage electrode sheets, during the process of blowing dust-containing gas through the wind channel, the high-voltage electric field can ionize the air molecules in the wind channel into positive and negative ions, and make the dust particles carry negative electricity, facilitating the subsequent adsorption and collection of dust particles. In addition, when negative ions come into contact with bacteria, mold, viruses and the like, the negative ions themselves carry excess electrons, which can destroy the molecular protein structure of bacteria, mold, viruses and the like, causing structural changes (protein polarity reversal) or energy transfer in bacteria, mold, viruses and the like, thereby killing bacteria, mold, viruses and other microorganisms. Therefore, the electrostatic dust removal device also has a sterilization effect, further improving the cleanliness of the air.

[0037] Further, the thickness of the reinforcing substrate 110 is 0.1mm-1.5mm. A reasonable thickness of the reinforcing substrate 110 can improve the strength of the reinforcing substrate 110 as much as possible while ensuring that the size meets the installation requirements, thereby improving the structural strength of the entire electrode sheet 100 and preventing it from deforming.

However, it is not limited to this, and in other embodiments, the conductive layer 120 can also be coated on any insulating layer 130, and the area of the conductive layer 120 is smaller than that of the insulating layer 130, so that the insulating layer 130 can completely cover the conductive layer 120 to ensure the insulation effect.

[0040] Further, the thickness of the conductive layer 120 is 0.01mm-0.1mm, and a reasonable thickness of the conductive layer 120 can reduce the thickness of the conductive layer 120 as much as possible while ensuring the conductive effect, so that the thickness of the reinforcing substrate 110 and the two insulating layers 130 can be adjusted in a larger range.

[0041] Further, the thickness of the insulating layer 130 is 0.1mm-1.2mm, and a reasonable thickness of the insulating layer 130 can ensure the structural strength of the insulating layer 130 and improve the cladding effect of the conductive layer 120, thereby enhancing the insulation effect.

When a plurality of electrode sheets 100 are arranged at intervals in the thickness direction, the insulating layer 130 can isolate the electric field sections 121 of the adjacent two conductive layers 120, avoid corona discharge between the adjacent two conductive layers 120, reduce the generation of ozone, reduce the risk of electric shock, and improve safety.

[0044] It should be noted that one end of the electrode sheet 100 is provided with a first limiting protrusion 140, and the other end is provided with a second limiting protrusion 150, and the first limiting protrusion 140 and the second limiting protrusion 150 are used for clamping positioning to fix the position of the electrode sheet 100, so as to ensure the stable formation of the air duct.

[0046] Further, the insulating layer 130 is also provided with a supporting protrusion 160. The supporting protrusion 160 and the first limiting protrusion 140 are oppositely arranged at the two ends of the insulating layer 130, the length of the supporting protrusion 160 is less than the length of the second limiting protrusion 150, and the supporting protrusion 160 is used for supporting the second limiting protrusion 150, so as to improve the structural strength of the second limiting protrusion 150, prevent the second limiting protrusion 150 from deforming or breaking during clamping with the second clamping groove, and be stable and reliable. Specifically, the supporting protrusions 160 of the two insulating layers 130 are arranged in overlap, the root of the second limiting protrusion 150 is clamped between the two supporting protrusions 160, and the two supporting protrusions 160 act together, so as to improve the root strength of the second limiting protrusion 150, prevent the second limiting protrusion 150 from breaking from the reinforcing substrate 110, and be safe and reliable.

[0050] Second embodiment

[0051] Please refer to Figure 4 The embodiment of the utility model provides an electrode sheet 100, compared with the first embodiment, the difference of the embodiment lies in the structure of the insulating layer 130.

The method of forming the insulating layer 130 by coating can effectively reduce the thickness of the insulating layer 130, and under the condition that the total thickness of the electrode sheet 100 does not increase, the thickness of the reinforcing substrate 110 can be adjusted in a larger range, so that the reinforcing substrate 110 can be set thicker, which is beneficial to improve the strength of the reinforcing substrate 110, and further improve the structural strength of the electrode sheet 100. In addition, by reducing the thickness of the insulating layer 130, the thickness of the entire electrode sheet 100 can also be reduced, which is beneficial to the thin and light setting of the electrode sheet 100, so that the volume of the electrode sheet 100 can be smaller, and the assembly is facilitated.
