In addition, a slight decrease in temperature when introducing fresh solution, namely in the lower part, also improves circulation due to the temperature difference.

Placing the tank lower and implementing it with a smaller volume worsens the circulation conditions, since there is a possibility of entrainment of electrolysis gases with the gas flow, which reduces the efficiency of the electrolysis process and increases the energy consumption for the process.

For this purpose, a supply unit for supplying gas, a unit for dosing and bathing part of the gas electrolysis system equipped with a system for automatic supply of a given pressure in the anode circulatory circuit. In addition, in its upper part, the anode circuit tank is equipped with a device for maintaining a constant level of anolyte in the tank, which allows for the automation of the cell operation process, ensuring automatic supply brine, as well as gas venting. The volume of the circulation circuit of the cathode chamber is significantly larger, since the volume of gas released in the cathode chamber is initially greater, and its decrease is less than a thirty-fold excess or an increase of more than a two-hundred-fold excess worsens the circulation. solution in the circuit. The location of the tank under the tank of the anode circuit ensures rational use of the space when creating normal conditions for the operation of the installation. From the cathode circuit tank, the products are removed in the form of a gas-liquid mixture, which is then fed to the gas separator. Supplying the unit with a special mixer, connected by means of control valves with a liquid outlet of the gas separator of the cathode circuit and with a gas outlet of the anode circuit and a water source, allows obtaining products not only in the form of gas but also and/or in the form of water. oxidizing agents, composition and characteristics of oxidizers are determined by quantitative characteristics products supplied to the mixer. In addition, the same system can be used for disinfection or purification of contaminated water using the proposed installation, which expands its functional capabilities. In this case, contaminated water is fed to the mixer (designated on the system as a water source).

The use of diaphragms with a smaller taper does not give a new result in comparison with cylindrical diaphragms. By using diaphragms with greater severity, the conditions of circulation of pastes in the chambers are disrupted, and, in addition, This results in the need to change the size of the device and increase the interelectronic communication, which leads to increasing energy consumption for the process. The same result is caused by increasing the thickness of the diaphragm walls. Reducing the dimensions of the diaphragm wall thickness below those indicated increases the thickness of the diaphragm, which affects the service life and complicates the processes of cell assembly and disassembly.

SSSΡ N. 886755, C 25 B 9/00, 1977]. However, the known solution uses cells with plane-parallel electrodes of a relatively large area, which requires greater investment to ensure the constancy of the interelectrode distance and the stability of the diaphragm properties throughout the entire 8 area, as well as complex connection with the system of supply of solutions and removal of products, and accordingly significant time and labor costs for dismantling and removing the cells. In the proposed solution, the use of relatively small cylindrical cells with high productivity reduces the dimensions of the installation and simplifies its maintenance.

The cathode circulation circuit is filled with water. The anodic circuit is filled with a saturated solution of alkali or alkaline earth metal chloride. Voltage is applied to the electrodes. After the process has been established, a saturated chloride solution is continuously and very slowly introduced from a container 6 into the lower part of the circulation circuit of the anode chamber of the electrochemical cell 1 using a dosing pump 5. The input is carried out at the lower point of the circulation circuit of the anode chamber. This solution circulates in the anode chamber due to gas litre: gases released at the anode - chlorine, chlorine dioxide, ozone, oxygen - carry the liquid upwards into container 2, where gas is separated from the liquid.

The pressure in the anode chamber of the reactor is higher than in the cathode and is within the range of 0.5 - 1.3 kgf/ cm2 , which prevents the penetration of hydroxide ions from the cathode chamber into the anode and thereby limits the solution of chlorine released at the anode in water. Sodium ions, under the action of a pressure difference and due to electrical diffusion transfer, move from the anode chamber through the diaphragm into the cathode chamber, carrying with them an additional amount of water. Thus, in each chamber the concentrated alkaline gaslite is circulated fast (ρΗ > 13).

The degree of salt decomposition reaches 95%, since the anodic process takes place in an acidic environment under high pressure.
