Description

The invention relates to a plasma technique and technology and can be used to obtain an electric discharge in a larger volume.

A known method (Plante G.11 Zeit. Phys. 1875. No. 80.S.1133) to obtain a gas-vapor discharge. With this method of producing a gas-vapor discharge, the discharge burns between the carbon anode and the electrolytic cathode in the range of the interelectrode distance from 1 and 7 mm at a discharge current of 50 to 500 mA and a discharge voltage of 500≤U≤1200 V. The disadvantage of this method is that the discharge burns by a spot spot on the anode by a contracted plasma column and a cone-shaped channel in the near-cathode region with an increase in the interelectrode distance, the stability of the vapor-air discharge significantly worsens and the discharge goes out. The discharge burns in a small volume - 70 mm ³ .

As a prototype, a discharge method was selected (Gaysin Az.F., Khakimov R.G., etc.) Gas-vapor discharge in the system "electrolyte jet - solid electrode" and its application (Bulletin of KSTU named after AN Tupolev No. 2. 1999, S. 62-65), consisting in the ignition of a multi-channel discharge between the stream - the electrode and the metal electrode, set the length of the stream l _c ≤52 mm and support the discharge current I≤6000 mA and U≤515 V. The multi-channel discharge in the prototype burns only between a metal electrode and an electrolyte jet without crushing unsteady jets. A disadvantage of the known method for producing a multi-channel discharge is that it burns only at the surface of a metal electrode (60 mm ³ ).

The technical problem to be solved is to obtain an electric discharge during combustion between an electrolyte consisting of successive continuous droplets — an anode and between a solid cathode in a large volume and outside the surface of a metal cathode.

The technical problem to be solved in a method for producing an electric discharge, including ignition of an electric discharge between an electrolyte stream and a metal electrode, is achieved by using an electrolyte consisting of consecutive continuous drops, which is an anode, and the metal electrode is a cathode obtained by applying voltage between electrodes equal U≥200 V at a discharge current I≥20 mA, with the overall length of the jet of droplets l _ck ≥2 mm diameter drops _to d ≥2 mm, at a flow rate drops RE LTL G _to ≥1 g / s, using process water or salt solutions, acids and alkalis in the process water, wherein the voltage U between the electrodes, I - discharge current, d _k - diameter of the droplet, l _ck - jet length of the droplets, G _K is the flow rate of the droplets.

A device for producing an electric discharge (FIG. 1) contains a cylindrical tube 1 for forming successive drops and supplying a positive potential, a metal cathode 2 — a stream of successive drops 3, a support for a solid cathode 4, and an electrolytic bath for collecting liquid 5.

2-19, photographs were taken using a Fastec HiSpec high-speed digital video camera. The shooting speed was 7529 frames per second. The entire discharge development process was observed during 776.4 [ms].

Consider the implementation of the method of producing an electric discharge. A method of producing an electric discharge involves igniting an electric discharge between an electrolyte stream 3 and a metal electrode 2, an electrolyte consisting of successive droplets 3 is used as an electrolyte stream 3 and a discharge is ignited between a continuous drop anode 3 and a solid cathode 2, obtained by applying a voltage between the electrodes equal to 200 V≤U, with a discharge current I≥20 mA, with a total droplet stream length l _ck ≥2 mm, droplet diameter d _k ≥1 mm, with an electrolyte drop rate G _k ≥1 g / s, and as an electrolyte use industrial water or a solution of salts, alkalis and acids in industrial water, where U is the voltage between the electrodes, I is the discharge current, d _k is the diameter of the droplet, l _c is the length of the jet of droplets, and G _k is the flow rate of droplets of droplets.

Figure 2-19 shows the development of an electric discharge between the continuous drip anode 3 and the solid cathode 2 near and outside the surface of the solid cathode. As can be seen from figure 2, microdischarges are observed in the droplet stream 3, and in figure 3 an electric discharge is ignited. This discharge goes out, and instead of it there are luminous microdots (Fig. 3 and Fig. 4), which scatter in different directions. After 26.6 [ms], a discharge is again ignited with many scattering and luminous microdots (Fig. 5). In Fig.6, the volume of the electric discharge almost doubles compared with Fig.5. With the further passage of time (Fig. 7), the volume of the electric discharge increases even more. On Fig-11 volume electric discharge begins to move to the right side due to natural convection of air, and the propagation of luminous transverse electrolyte waves on the surface of the metal cathode is observed below. As can be seen from Fig. 12, the electric discharge decreases in volume and begins to separate from the surface of the metal cathode and the interelectrode gap. However, an electric discharge occurs between the departing plasma volume and the metal cathode 2 from the left end (Fig. 12 and Fig. 13). At Δt = 765.4 [ms], the electric discharge burns outside the interelectrode gap and quickly begins to move away (Fig. 14, Fig. 15, Fig. 16, Fig. 17). At 766 [ms], the discharge glow significantly decreases and the discharge gradually goes out (Fig. 18).

The above conditions are chosen exactly as Only under such conditions is the receipt of the declared electric discharge possible.

Thus, in the proposed method for producing an electric discharge, the technical problem to be solved for obtaining an electric discharge in a large volume near and outside the interelectrode gap of 2000 mm ³ or more in comparison with the prototype is achieved by igniting a discharge between a continuous droplet anode and a metal cathode, and as electrolyte use industrial water or a solution of salts, alkalis and acids in industrial water. In the prototype, the burning of the discharge is possible only at the point of contact of the metal electrode with the discharge and can be 60 mm ³ in volume, and in the proposed method, the electric discharge burns near and outside the interelectrode gap and exceeds almost 35 times in volume.
