The invention relates to methods for producing, researching and using low-temperature plasma and can be used in plasma chemistry, plasma technologies for processing materials and plasma technology, in particular in plasma-chemical reactors.

A known method of producing an electric discharge in electrolyte vapors and a device for its implementation [1], the object of the invention is to increase the active working area of the discharge by increasing the length of the discharge.

The disadvantage of the device [1] is the presence of a solid-state anode, which wears out during operation and therefore has a limited service life.

The closest to the claimed technical solution, the prototype, is a method for producing an electrolyte electric discharge and a device for its implementation [2], the objective of the invention is to increase the active working area of the discharge.

The disadvantage of this device [2] is also the presence of a solid-state anode, which wears out during operation and therefore has a limited service life.

The purpose of the claimed invention is aimed at increasing the service life of the plasmatron due to the absence of erosion in liquid electrolyte electrodes.

The goal is achieved in that a method for producing an electric discharge between two electrode assemblies, which consists in the fact that the discharge is excited between the flows of two electrolytes flowing from the upper parts of the corresponding two prismatic cathode and anode electrode assemblies located horizontally, while a device for implementing the method comprising two electrically isolated hydraulic systems for the circulation of electrolytes and an electrolyte cathode and electrolyte anode electrode assemblies, whereby the body of the electrode assemblies have the shape of a prism with a distribution channel in the center of the section, with a supply channel in the side of the section and with a discharge channel in the upper part of the section, moreover, the longitudinal dimensions of the prism are an order of magnitude larger than the transverse dimensions, and the bodies of both electrode assemblies are made of a heat-resistant dielectric material and have the same appearance and design, also inside the body of each electrode assembly there is a continuous current lead shnogo solid-state prismatic rod, coaxially placed inside the longitudinal channel in the housing of the corresponding electrode unit with the formation of an annular gap for the flow of electrolyte and hermetically fixed at both ends of the corresponding electrode unit, and the current supply of the anode electrode unit is made of a solid-state non-metallic conductive corrosion-resistant material, and the current supply of the cathode electrode unit made of solid-state conductive corrosion-resistant metal, except that the current leads are connected to the corresponding terminals for the supply of electrical energy.

FIG. 1 shows a device for implementing the method. The arrows indicate the direction of movement of the liquid electrolyte.

The device for implementing the method (Fig. 1) consists of two outwardly identical horizontally located prismatic electrode assemblies "K" and "A"; two electrically isolated hydraulic systems "GS-K" and "GS-A".

Electrode assembly "A" (anode assembly) consists of the following parts: 1 - anode supply channel, 2 - non-metallic anode current supply, 3 - anode distribution channel, 4 - anode housing, 5 - anode discharge channel, 6 - electrolyte flow flowing down from anode assembly.

The electrode assembly "K" (cathode assembly) consists of the following parts: 8 - electrolyte flow flowing down from the cathode; 9 - cathode outlet channel; 10 - cathode body; 11 - cathode distribution channel; 12 - cathode metal current lead; 13 - cathode supply channel.

Between the electrode nodes "K" and "A" there is an interelectrode gap 7 formed by the nearest electrolyte flows.

The electrode assembly "A" (anode assembly) is connected to the positive terminal 14. Under the assembly there is a hydroelectric station "GS-A".

The electrode assembly "K" (cathode assembly) is connected to the negative terminal 15. Under the assembly there is a hydroelectric station "GS-K".

The device for implementing the method (Fig. 1) operates as follows. Prior to the initiation of the discharge with the help of two electrically isolated hydraulic systems "GS-K" and "GS-A", a continuous circulation of two electrolyte flows electrically isolated from each other through the electrode assemblies "A" and "K" is started at a flow rate sufficient to ensure stable discharge in the interelectrode gap 7, and the flow rate is selected empirically. To ensure circulation from the "GS-A" hydraulic system, the electrolyte flow is continuously directed into the anode supply channel 1 of the "A" electrode unit, and from the "GS-K" hydraulic system, the electrolyte flow is continuously directed into the cathode supply channel 13 of the "K" electrode unit.

In the electrode unit "A" the electrolyte flow flows through the anode supply channel 1; through the anode distribution channel 3, formed between the anode housing 4 and the non-metallic anode current lead 2, through the anode outlet channel 5. Then the electrolyte flow exits into the upper part of the electrode assembly "A" and flows into the hydraulic system in both directions as a flow 6 " GNS-A ", where the electrolyte is cleaned, fed, stored and cooled.

In the electrode unit "K", the electrolyte flow flows through the cathode supply channel 13, through the cathode distribution channel 11, formed between the cathode housing 10 and the cathode metal current supply 12, through the cathode outlet channel 9. Then the electrolyte flow enters the upper part of the electrode unit "K" and in both directions from it in the form of flow 8 flows into the hydraulic system "GS-K", where the electrolyte is cleaned, fed, stored and cooled.

The discharge between the flowing electrolyte flows in the interelectrode gap 7 is initiated, for example, by the explosion of a thin metal wire, when electrical energy is supplied to the terminals 14 and 15, connected to the corresponding non-metallic anode current lead 2 and the cathode metal current lead 12.
