Technical field

The invention relates to devices for electrochemical treatment of water in a duct with an increased shelf life of treated water and can be used in the medical, agricultural, food and cosmetic industries, as well as in everyday life.

State of the art

The use of new unique Russian technologies, patented devices and methods made it possible, using these achievements and on their basis, to create simple but effective new generation devices for producing water with improved qualities in real time.

In particular, from the patent for utility model RU74910 U1, 07/20/2008, cl. C02F 1/46, it is known a device for activating a liquid containing a cylindrical reactor with an electronic unit located in it, is installed in the upper part of the reactor with the possibility of vertical movement along the guide open from the top cone with a vertical handle. Inside the filter tank there is a fine filter element fixed to the bottom of the filter tank using a “fungus”.

The disadvantage of this device is cumbersome, i.e. 5 l of water is treated at a time, which on the third day loses its activity, frequent preventive maintenance of the filter (10-12 l of water), then washing and acid treatment, frequent mechanical cleaning of the anode, for which it is removed using a special key that is not included in the installation kit, certain requirements for the salinity of the treated water and its temperature.

The closest technical solution inherently achieved technical result for this invention is a device for electrochemical treatment of water, described in patent RU2531284 C1, 10/20/2014, class C02F 1/46, containing a power supply unit with stabilization of the operating current, cathode, anode, housing compressing the anode with holes, an insulator for fixing the cathode in the center, a cover and a handle filled with sealant.

The disadvantage of this device is the inability to conduct electrochemical activation of water continuously in the stream, which dramatically reduces the range of application of the device.

Disclosure of invention

The technical problem to which the present invention is directed is to increase the productivity of the device while reducing its cost and increasing the shelf life of treated water without changing its physico-chemical properties.

This technical problem is solved due to the fact that the device for the electrochemical treatment of water in the duct with an increased shelf life of the treated water contains a housing with inlet, outlet and drain fittings, a power source, electrodes in the form of anodes and cathodes installed in the guides, while the latter are connected to the device case by means of flexible leads and detachable connections, the anodes and cathodes are located in the case alternating relative to each other with the formation of a labyrinth passage for the flow of the process attracted water with the possibility of its multiple passage, and above which there are separate collections of oxygen and hydrogen, one of which is made with the possibility of adding to the treated water when pouring it into the container.

The number of oxygen collectors is two, and hydrogen is one, common to all cathodes.

The oxygen and hydrogen collectors are equipped with fittings.

The technical result of the invention is to improve the quality of water treatment while increasing the shelf life of treated water without changing its physico-chemical properties.

Brief Description of the Drawings

The implementation of the invention

The claimed device for electrochemical water treatment consists of a power supply with stabilization of the operating current (not shown in the drawing), as well as a housing (4) with input (1), output (2) and drain (3) fittings. Separate gas collectors are installed in the housing (4): oxygen (О ₂ ) with discharge fittings (5) and hydrogen (Н ₂ ), containing a gas collector cover (6) with a hydrogen outlet (12). In this case, the number of oxygen gas collectors is two, and one hydrogen, common to all cathodes.

The cathodes (7) and anodes (8) are alternately mounted in the housing (4), arranged in such a way as to provide a multi-pass water flow washing the electrodes on both sides. The cathodes and anodes are fixed using guides (9) and contact with which is carried out through the walls of the housing (4) using flexible leads (10) and bolted joints (11). Moreover, these cathodes and anodes are fixed, as noted above, alternating relative to each other to opposite walls of the housing with the formation, thus, of a labyrinth passage for the flow of treated water, shown in figure 2 by arrows.

The device operates as follows.

Activated water is fed into the housing (4) of the device through the inlet fitting (1) and the housing (4) is filled until water appears from the drain fitting (3). Then set the desired flow rate of water from the outlet fitting (2) and increase the flow of water through the inlet fitting (1) until it appears from the drain fitting (3). The electrodes (7), (8) are supplied with power and the operating current necessary to obtain water with a given redox potential is set. As a result of electrochemical processes, oxygen is formed at the anodes (8), which is discharged into the atmosphere through the discharge fittings (5), and hydrogen is formed at the cathodes (7), which is collected under the cover of the gas collector (6) and is added to the tank during bottling of activated water water, which allows to increase the shelf life of activated water up to a year. Sludge generated during the operation of the device is removed through the drain fitting (3) together with water.

The invention is illustrated by a specific example of the use of the proposed device.

In a case (4) welded from vinyl plastic with a thickness of 10 mm and dimensions of 820 × 220 × 120 mm, they are cut at a height of 100 mm from one end side at a distance of 20 mm from the walls of the inlet (1) and outlet (2) fittings with a diameter of ½ inch, and above an outlet fitting (2) at a height of 110 mm cuts a drain fitting (3) with a diameter of ½ inch. In the guides (9) made of vinyl-plastic, three cathodes (7) are made of stainless steel 12XH9T with a size of 740 × 120 and a thickness of 2 mm, as well as two anodes (8) of aluminum with a size of 740 × 120 and a thickness of 2 mm. The distance between the walls and cathodes 10 mm Further, the electrodes are installed in increments of 20 mm.

In the upper wall part of the electrodes, using bolted connections (11) M5 and flexible leads (10) from a stranded wire with a cross section of 2.5 mm ² , a contact was made to the outside of the housing (4) for connecting the power source using bolted connections M5 (11) . On the cover of the power source (not shown in the drawing) using bolted connections (11) M5. On the cover (6), made of vinyl plastic 10 mm thick, which is a hydrogen collector, over the anodes, oxygen collectors (5) made of tinplate 1 mm thick and coated with electrotechnical varnish are fixed using hollow tubes made of 12XH9T stainless steel with M10 thread. In the upper part of the lid (6), a fitting (12) of vinyl plastic with a diameter of ½ inch is mounted to remove hydrogen, used when filling containers with activated water to increase its shelf life while maintaining its physicochemical properties. The device is powered from a stable current source of 9A.

When treating water with a flow rate of 0.5 m ³ / h, the redox potential assumes a value of 460 mV while maintaining the pH value at 7.2, which allows the use of treated water for various purposes in any quantities. The change in the level of redox potential of the treated water can be carried out by changing the current strength and the flow rate of the treated water.
