The utility model relates to the field of chemical technology, in particular to devices for the electrochemical treatment of water and / or aqueous solutions, and can be used in processes related to the electrochemical regulation of acid-base, redox properties and catalytic activity of water and / or aqueous solutions as well as in the processes of electrochemical production of various chemical products by electrolysis of aqueous solutions, in particular, a mixture of oxidants in the electrolysis of an aqueous solution of chlorides direct and alkaline earth metals.

Known flow-through electrochemical modular element PEM-3 [RF Patent No. 2078737 IPC C02F 1/461 (1994.05)]. A device for electrochemical water treatment consists of vertical kaoxial rod and cylindrical electrodes, the last of which is installed in dielectric bushings, a ceramic diaphragm, coaxially placed between the electrodes and dividing the interelectrode space into the electrode chambers, channels and nozzles for supplying and drainage of the treated water into the chamber of the cylindrical electrode, has an upper and lower dielectric collector heads with channels, provided nipples for supplying and discharging the treated water into the core electrode chamber.

The disadvantage of this apparatus is that work in a confined space makes possible the formation of a gas phase (gaseous oxidants, molecular chlorine and hydrogen), the removal of which is not provided for from an electroactivated liquid.

The closest known analogues is the electrochemical modular element PEM-7 [RF Patent No. 2176989 IPC С25В 1/46 (2000.01)]. The reactor of the installation for processing aqueous solutions contains vertical coaxial cylindrical inner hollow and outer electrodes, lower and upper dielectric bushings, along the axis of which holes are made, and on the surface of the bushings the input and output channels communicating with the camera of the external electrode are output, respectively. A ceramic diaphragm is made in the cell, coaxially mounted between the electrodes and dividing the interelectrode space into the electrode chambers. The inner hollow electrode is made with perforations. The inlet and outlet nozzles of the chamber of the inner electrode are installed respectively on the lower and upper ends of the inner hollow electrode and communicate with its cavity.

This device has the following disadvantages:

In the process of electrochemical treatment of water and / or an aqueous solution, molecular chlorine, hydrogen and oxidants are formed, which negatively affects the further use of liquid for pre-treatment of plant materials, to improve the yield of extractive substances. It is not provided for the removal of the gas phase from the apparatus, which, when operating at high capacities, can be explosive.

The technical result is the provision of obtaining electrified liquids without molecular chlorine, hydrogen and gaseous oxidants.

The technical result is achieved by the fact that the apparatus for producing electroactivated liquids, consisting of an external cylindrical and internal electrodes, a coaxially located diaphragm dividing the interelectrode space into electrode chambers, input and output are installed for supplying and discharging treated water

the nozzles are additionally equipped with two internal rod electrodes and a diaphragm, which forms a chamber between the diaphragms in the interelectrode space, an overflow pipe to maintain the required liquid level and fittings for venting the gas phase.

The apparatus for producing electroactivated liquids contains three rod electrodes, which allows for a more complete and efficient electrolysis process. The device is equipped with two diaphragms that divide the interelectrode space into three electrode chambers, which makes it possible to drain sodium, chlorine and oxidant ions from the chamber between the diaphragms through an overflow pipe, which maintains the required liquid level in the device and ensures free removal of the gas phase from the device through top of the device fittings.

Thus, the set of essential features of a utility model set forth in the utility model formula, allows to achieve the desired technical result.

Figure 1 shows the apparatus for producing electroactivated liquids.

The device for producing electroactivated liquids contains an external cylindrical electrode 1 and three internal rod electrodes 2, an external 3 and an internal 4 coaxially located diaphragms that divide the interelectrode space into electrode chambers, a pipe 5 for supplying water to the device, an overflow pipe 6 is made in the lower part of the device that maintains the liquid level and removes it from the apparatus, pipe 7 for discharging catholyte, pipe 8 for draining anolyte, fittings 9, 10 for venting gas phases are located in the upper part of the device .

The apparatus for producing electroactivated liquids is as follows. Through the pipe 5 into the chamber between the diaphragms 3, 4

water and / or aqueous solution is supplied and fills the entire interior. After applying voltage in the chamber of the external electrode 1, positively charged ions (catholyte) accumulate under the influence of an electric field, and negatively charged ions (anolyte) in the chamber at the inner rod electrodes 2. In the process of electrolysis, reaction by-products are formed: sodium ion, chlorine, molecular chlorine, hydrogen, oxidants. The removal of ions and oxidants is carried out through the chamber between the diaphragms 3, 4, which is flowing, into the overflow pipe 6, which maintains the necessary liquid level in the apparatus, which ensures free removal of the gas phase through the fittings 9, 10. The fitting 9 serves to remove molecular hydrogen from the apparatus and fitting 10 is molecular chlorine. Anolyte is drained through pipe 7, a catholyte is drained through pipe 8.
