Description

The utility model relates to chemical technology, namely, devices for electrochemical treatment of water, in order to regulate its acid-base properties and catalytic activity, and can be used to obtain detergents, disinfectants, sterilizing and therapeutic solutions.

A device for producing washing and disinfecting solutions is known, comprising at least one electrochemical cell made of vertical coaxial rod electrodes installed in dielectric bushings and an ultrafiltration diaphragm coaxially mounted in the bushings between the electrodes included in the strapping of two gas separators connected as with anode and cathode chambers so that the gases generated during electrolysis are supplied from the anode chamber to the cathode, and from the cathode to the anode (RU 2076847, C1, C 02F 1/46, 04/10/97).

A disadvantage of the known solution is the unsatisfactory hydrodynamics, due to which the gases introduced into the anode and cathode chambers lead to the formation of gas plugs in the chambers and uneven operation of the device. The increased gas content in the anode and cathode chambers leads to a decrease in the efficiency of the entire device, in addition to

This device can be obtained simultaneously only on one composition of the solution: anolyte and catholyte.

The closest in technical essence and the achieved result, adopted as a prototype, is a device for cleaning and disinfecting solutions, containing at least one electrochemical cell made of vertical coaxial cylindrical and rod electrodes installed in dielectric bushings with a coaxial ultrafiltration diaphragm, mounted on the bushings between the electrodes and dividing the interelectrode space into electrode chambers, with channels for supply and the solution to be fed into the electrode chambers in the lower and upper bushings, respectively, the current source, the positive and negative poles of which are connected to the electrodes, the supply line of the processed solution is connected to the negative electrode chamber, the output of the negative electrode chamber is connected by an additional line to the entrance to the positive electrode chamber and of this line, a device is installed to enable the removal of part of the degassed treated solution from the negative electron chamber yes, and the special line installed capacity comprising a mixture of carbon particles and manganese dioxide with an entrance at the top and an outlet at the bottom (RU 2088539, C1, C02F 1/46, 27.08.97 g).

The disadvantage of the prototype is the inability to obtain more than two activated solutions at the same time.

The objective of the utility model is to expand the functionality of the device by obtaining a larger number of simultaneously obtained activated solutions of different characteristics.

The task is ensured by the fact that the device for producing washing and disinfecting solutions contains at least two or multiple to two electrochemical cells made of vertical coaxial cylindrical and rod electrodes installed in dielectric bushings with a coaxial ultrafiltration diaphragm,

mounted on the bushings between the electrodes and dividing the interelectrode space into the electrode chambers, with channels for supplying and discharging the treated solution into the electrode chambers, respectively, in the lower and upper bushings, the current source, the positive and negative poles of which are connected to the electrodes, the supply line of the treated solution is connected to the input or by the output of the negative electrode chamber of the first electrochemical cell, respectively the output or input of which is connected by an additional line to two inputs the chambers of the positive electrode of the first and second electrochemical cells, the outputs of the chambers of the positive electrode are connected by an additional line to the input or output of the chamber of the negative electrode of the second electrochemical cell.

The output or input of the first electrochemical cell is connected by an additional line to the input or output of the negative electrode chamber of the second electrochemical cell, the output or input of which is connected by an additional line to the inputs of the positive electrode chambers of the first and second electrochemical cells, the outputs of the chambers of which are connected in parallel and a treated solution is selected from them further use, on additional lines installed devices for the selection of the treated solution from the chambers of positive and negative electrodes of electrochemical cells.

The electrochemical cells are interconnected by elastic tubes and dielectric fittings, and the cross-sectional area of the tube opening is equal to the cross-sectional area of the fittings.

Figure 1 and 2 presents options for hydraulic circuits of the device for obtaining detergents, disinfectants, sterilizing and therapeutic solutions.

To simultaneously obtain catholyte and two varieties of anolyte (see Fig. 1), water is supplied through a water supply line 1 to a metering device consisting of a pump 2 and valve 3, in which, if necessary, water and electrolyte are mixed from tank 4, as an electrolyte a solution of any water soluble chemical compound may be used; or

chemical element, then the resulting solution enters the cathode chamber of the negative electrode of the first electrochemical cell 5 with a valve 6 for catholyte selection with pH 9-10, the treated solution from the cathode chamber of the cell 5 enters the second electrochemical cell 7 having a valve 8 for taking anolyte with pH 2-4 along an additional line 9 simultaneously to the inputs of the anode chambers of the positive electrode of the first 5 and second 7 electrochemical cells. Then, from the parallel connected inputs of the anode chambers of cells 5 and 7, the treated solution is fed through line 10 to the input of the cathode chamber of the negative electrode of the second cell 7, from the output of which solution A2 (anolyte) with a pH of 6-8 is taken through line 11.

Figure 2 shows a scheme for producing anolyte and two varieties of catholyte, in which water is supplied from a pressure line or pump through a water supply line 1 to a metering device consisting of a pump 2 and a valve 3 in which, if necessary, water and electrolyte are mixed from a tank 4 , a solution of any water-soluble chemical compound or chemical element can be used as an electrolyte, then the resulting solution enters the cathode chamber of the negative electrode of the first electrochemical cell 5 with a tap 6 To a solution of the activated selection. At the input of the second electrochemical cell 7, having a tap 8 for sampling the activated solution K2 (catholyte) with a pH of 9-11, the treated solution enters through line 9 to the input of the cathode chamber of the second electrochemical cell 7, from the output of which the treated solution enters along line 10 simultaneously to the inputs of the anode chambers of the first 5 and second 7 electrochemical cells, from the parallel connected outputs of the anode chambers of which selection is made for further use of the treated AN solution (anolyte) with a pH of 6-8.

As a result of research, it was found that, in order to reduce electromagnetic interference and hydraulic resistance, and, as a consequence, increase the productivity of the device, it is advisable to connect electrochemical cells with elastic tubes and

dielectric fittings, and the cross-sectional area of the holes of the tubes is equal to the cross-sectional area of the holes of the fittings.

Obtaining different quality of processing aqueous solutions provides their new properties, determined by changing the structure of water, which cannot be achieved by simple dilution of water with a high pH control, which undoubtedly indicates the inventive step of the claimed proposal.

The proposed solution allows you to simultaneously receive for different purposes (disinfection of rooms, sterilization of the instrument, etc.) more than two varieties of activated solutions with different characteristics, which expands the functionality of the device compared to analogues.
