Description

Water-cooled ozone generator electrode

Technical field

[0001] The present invention relates to the field of plate type ozone generating devices, and in particular to a water-cooled ozone generator ground electrode.

Background technique

[0002] The high-pressure discharge type ozone generator is divided into cooling methods, and is water-cooled and air-cooled. When the ozone generator works, it generates a lot of heat and needs to be cooled. Otherwise, the ozone will decompose due to high temperature. High performance ozone generators with consistent overall performance are typically water cooled. The water-cooled generator has good cooling effect, stable operation, no attenuation of ozone, and can work continuously for a long time. When selecting the generator, the water-cooled type should be used as much as possible.

[0003] There is a problem in that the body of the electrode of the conventional water-cooled ozone generator is a cylindrical stainless steel body, and the main body is provided with a discharge groove and a non-discharge rib at intervals, because of the cylindrical shape. The structure is difficult to process, the processing precision is low, and the spacing between the adjacent two discharge grooves is relatively large, so that the electric field intensity generated during high-voltage discharge is low, and the final ozone yield is low.

Summary of the invention

The invention provides a water-cooled ozone generator electrode capable of improving ozone yield.

[0005] The technical solution of the present invention is achieved by including a ground electrode body and a cooling water through hole, wherein the surface of the ground electrode body is provided with discharge grooves spaced apart from each other and a non-discharge convex for positioning the discharge gap Article,

[0006] the ground electrode body is in the form of a flat plate;

[0007] The spacing between the axes of two adjacent discharge grooves is 0.1-0.25 mm;

[0008] The spacing between adjacent two hole walls of two adjacent cooling water through holes is 3-5 mm.

Compared with the prior art, the electrode of a water-cooled ozone generator provided by the present invention improves the existing cylindrical body into a flat body, which is compared with a cylindrical shape in a flat body. It is easier to process on. The spacing between the axes of the two adjacent discharge grooves is 4-6 mm, and the spacing between the axes of the adjacent two discharge grooves is reduced to 0.1-0.25 mm in the present invention. Since the distance between the high-voltage discharges is increased after the interval between them is reduced, the concentration of the anti-plasma generated in the discharge of oxygen is increased, and at this time, the concentration of ozone generated is increased. Because a large amount of heat is generated during high-voltage discharge, and ozone is decomposed into oxygen at 70 degrees Celsius or above, the spacing between adjacent two hole walls of two adjacent cooling water holes is set to 3-5 mm. The more cooling water through holes that can be placed on the ground electrode body, the higher the heat dissipation efficiency. The denser the cooling water hole is set, the faster the heat dissipation rate is, and the higher the efficiency, the less easily the generated ozone is decomposed. Therefore, the electrode of a water-cooled ozone generator provided by the present invention can increase the ozone yield.

[0020] Compared with the prior art, the electrode of a water-cooled ozone generator provided by the present invention improves the existing cylindrical body into a flat body, which is compared with a cylindrical shape in a flat body. It is easier to process on. The spacing between the axes of the two adjacent discharge grooves is 4-6 mm, and the spacing between the axes of the adjacent two discharge grooves is reduced to 0.1-0.25 mm in the present invention. Since the distance between the high-voltage discharges is increased after the interval between them is reduced, the concentration of the anti-plasma generated in the discharge of oxygen is increased, and at this time, the concentration of ozone generated is increased. Because a large amount of heat is generated during high-voltage discharge, and ozone is decomposed into oxygen at 70 degrees Celsius or above, the spacing between adjacent two hole walls of two adjacent cooling water holes is set to 3-5 mm. The more cooling water through holes that can be provided on the ground electrode body 1, the higher the heat dissipation efficiency.

The spacing between the axes of the two adjacent discharge grooves is 4-6 mm, and the spacing between the axes of the adjacent two discharge grooves is reduced to 0.1-0.25 mm in the present invention. Because there will be room between After the distance is reduced, the field strength of the high-voltage discharge is increased, and thereafter, the concentration of the plasma generated by the discharge of oxygen is increased, and at this time, the concentration of ozone generated is increased. Because a large amount of heat is generated during high-voltage discharge, and ozone is decomposed into oxygen at 70 degrees Celsius or above, the spacing between adjacent two hole walls of two adjacent cooling water holes is set to 3-5 mm.
