Description

A high-voltage ion sheet and electrostatic dust removal equipment including the high-voltage ion sheet

Technical Field

The invention belongs to the field of air purification equipment, and in particular relates to a high-voltage ion sheet and an electrostatic dust removal device comprising the high-voltage ion sheet.

Background Art

There are two types of electrostatic dust removal equipment used to absorb dust: one is a plate structure and the other is a honeycomb structure. In the electrostatic dust removal equipment with a plate structure, there are two types of plates, one is a high-pressure dust collecting plate and the other is a low-pressure dust collecting plate. Both the high-pressure dust collecting plate and the low-pressure dust collecting plate are flat plate structures.

At present, all the plates in the plate-structure electrostatic precipitator equipment on the market use ordinary flat plate structures. For high-voltage static electricity with pointed discharge characteristics, the middle part plays a relatively small role.

In terms of the working principle of electrostatic dust removal equipment, it uses the tip discharge principle of high-voltage static electricity to ionize the air and generate a large amount of electric charge, which is adsorbed on the dust in the air through collision. The electrostatic field force then causes the dust to adsorb on the grounded plate, thereby achieving the effect of filtering and purifying the air.

Due to the existence of the tip discharge phenomenon, when a flat plate is used to act on an electrode, discharge fields are only generated on both sides of the plate. In the middle part of the plate, only a parallel electric field exists, and the amount of charge in the air is relatively low.

Summary of the invention

In order to solve the above technical problems, the present invention proposes a high-voltage ion sheet and an electrostatic dust removal device including the high-voltage ion sheet.

In order to achieve the above object, the technical solution of the present invention is as follows:

A high-voltage ion sheet comprises an ion sheet body and one or more discharge holes arranged on the ion sheet body and distributed in a matrix.

The high-voltage ion sheet of the present invention has a simple structure. Discharge holes of appropriate number, size and shape are added to the ion sheet body. The edges of the discharge holes are used to exert the effect of tip discharge, thereby increasing the charge content in the air, improving the filtering efficiency, and effectively reducing the weight of the high-voltage ion sheet.

Based on the above technical solution, the following improvements can be made:

As a preferred solution, the discharge hole is in a circular, rectangular or long waist shape.

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

In order to achieve the purpose of the present invention, in some embodiments of a high-voltage ion sheet and an electrostatic precipitator including the high-voltage ion sheet, as shown in Figure 1, a high-voltage ion sheet includes: an ion sheet body 1 and one or seven discharge holes 2 arranged in a matrix on the ion sheet body 1. In this embodiment, the discharge hole 2 is a long waist hole.

The high-voltage ion sheet of the present invention has a simple structure, and discharge holes 2 of appropriate number, size and shape are added to the ion sheet body 1, and the edge of the discharge hole 2 is used to play the role of tip discharge, thereby increasing the charge content in the air, improving the filtration efficiency, and effectively reducing the weight of the high-voltage ion sheet 1. The charge content in the chassis of the electrostatic dust removal equipment of the present invention is high, and the overall filtration effect is better.

In order to further optimize the implementation effect of the present invention, in other embodiments, the remaining characteristic technologies are the same, except that, for the high-voltage ion sheet, the ion sheet body 1 includes a first plate body 11 and a second plate body 12 arranged in parallel, and discharge holes 2 are provided on the first plate body 11 and the second plate body 12. Relative sliding can occur between the first plate body 11 and the second plate body 12. The discharge holes 2 on the first plate body 11 and the discharge holes 2 on the second plate body 12 are completely overlapped or partially overlapped.
