Double-dielectric barrier discharge structure

Technical Field

The utility model belongs to the technical field of two dielectric barrier discharge, specifically speaking relates to two dielectric barrier discharge's structure.

Background

The low-concentration ozone generator and the low-temperature plasma generator are devices manufactured by an electrode discharge principle, and the existing double-dielectric barrier discharge is basically formed by combining solid materials with fixed dielectric strength.

Problem 1 exists: the large-area generator needs the combination of a plurality of generating tubes, so that the line joints are numerous, poor contact is easy to cause, and various faults and accidents are caused by the poor contact.

Problem 2 exists: the problem of non-adjustable gap size exists between the two solid media, so that the discharge is not uniform.

Problem 3 present: with a fixed product gap, the output can only be adjusted by adjusting the input power, which results in a significant drop in output capacity.

There is a problem 4: the small gap mounting and assembling between the two solid media easily causes the problem of incapability of assembling due to tolerance or forcibly assembles a low-quality product with a large gap, thereby causing material waste and simultaneously reducing the yield and the performance of the product.

In view of this, the present invention is provided.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model adopts the following basic concept:

the utility model provides a structure that two media block discharge, includes passive electrode, insulating head, first medium, second medium and active electrode, first medium is the half closed form of cavity, and one side is opened and is equipped with the port, and the port blocks through the insulating head, has the passive electrode of interlude in first medium inside in the insulating head, and the surface paste of first medium is provided with the active electrode, and the inside packing of first medium has the second medium, the second medium is dielectricity adjustable liquid and dissolves.

Detailed Description

To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and the following embodiments are used to illustrate the present invention.

Example 1

As shown in fig. 1, the whole structure adopts a conventional shape, which is cylindrical or rectangular, 3 is a hollow semi-closed shape, one side of which is provided with a port, the port is blocked by 2, 5 is adhered to the surfaces of 1 and 3 inserted into 3 in 2, 4 is filled in 3, and 4 is a liquid solution with adjustable dielectric property.

The working principle is as follows: the liquid solution is tightly combined with the first medium 3, so that the outer layer of the first medium 3 is more uniform, mild and full in discharge, and the electric field intensity and the discharge performance are more uniform under low voltage. The low voltage reduces the effect of ionized oxygen, thereby reducing the ozone yield, and the electric field strength is not wrong, thus ensuring that plasma with higher and stable concentration can be obtained under the conditions of low voltage and low electric field strength.

Equipment: the device comprises a first AlphaLabAIC3000 ion detector, a first atmospheric ozone detector, a first digital display direct current power meter, a first air feeder, a first direct current transformer (voltage: 3.6-12V current: 2A), a first high-voltage generator (12V rise 3000V +/-1 KV), a first 4.5W patent generator head (hereinafter referred to as head A) and a first company low-temperature plasma 6W generator head (hereinafter referred to as head B).

The experimental data are as follows (detector distance from generator 15 CM):

the experimental results are as follows:

the generator of the patent can be analyzed from experimental data, under the same voltage, the performance is greatly improved due to the change and optimization of the structural material of the generator, and under the condition of lower output power, low-concentration ozone and plasma (positive and negative plasmas) with higher concentration are generated at the output end
