Description

The invention relates to plasma chemistry and can be used in areas where ozone is required: chemical production, medicine, agriculture.

The known method of producing ozone is through a device made in the form of two coaxial cylindrical arrays with perforations, which are one electrode. The second electrode is made in the form of an insulated drive wound spirally on the inner cylinder. The method is based on the generation of a barrier surface discharge between the outer surface of the inner cylindrical discharge and the outer surface of the conductor and the bombardment of this discharge of air flow.

The ozone production method implemented by this device has a low productivity due to the need for a large amount of energy for pumping air, as well as a small extent of barrier surface damage.

The closest to the present invention is a method of producing ozone, based on the generation of two barrier surface discharges between two insulated mutually corona conductors, bombarding the air flow. This method is implemented by an ozonizer made in the form of a pipeline, inside which two insulated conductors are stretched from each other. which are supplied with alternating voltage from a high-voltage power source.

This method has low productivity due to the need for a large amount of energy to pump air and the short extent of the barrier surface discharge.

The aim of the invention is to improve the performance of the method.

The goal is achieved by lengthening the surface barrier discharge. For the bombardment of air flow, three barrier surface discharges are used,

chassis due to the use of three insulated conductors. At the same time, the barrier surface discharges generate a cross-sectional charge, which each of them mutually coronades with the other two. This can be provided with. the inclusion of conductors in a closed three-phase current circuit (delta). However, the generation of barrier discharge is not limited to a three-phase closed circuit, i.e. a triangle. In this case, all variants of three-phase electrical circuits are possible in implementation: star-star, star-triangle, triangle-triangle, triangle-star. The proposed option is dictated by the optimal (best) conditions for generating the bit in achieving the objective of the invention.

As a device for the implementation of the proposed method for producing ozone, a tube is used within which three insulated conductors are drawn with the possibility of touching the surfaces of the insulation along their entire length or with a small gap between them. The conductors are connected to the high-voltage AC source in a triangular circuit. As a result, the extent of generation of barrier surface discharge increases quite widely in the industry and effective in the use of a three-phase power source,

The drawing shows a diagram of an apparatus for implementing a method for producing ozone.

The method is carried out as follows.

Three barrier surface discharges are generated that mutually corona each other in a closed three-phase electric circuit with subsequent bombardment of air flow. A device that implements the method contains a pipeline t and three insulated conductors stretched therein 2-4. The conductors are connected to a high voltage AC source 5 in a triangular pattern, i.e. For each phase of the power source I, I, H, connect a separate conductor. As a result, a discharge arises from the insulating surface of each conductor, mutually coroning with the other two discharges. Thus, the possibility of a three-phase excitation of the barrier surface discharge increases the length of the discharge, which is unambiguously associated with an increase in the productivity of the method. In addition, the proposed method reveals the wide possibilities in the implementation of a variety of designs of ozonizers with simplicity and high performance.
