Description

The utility model relates to the field of water treatment, in particular, to the electrochemical treatment of water and can be used to activate water and aqueous solutions in order to give them acid-base and redox properties used in technological and domestic practice.

A device for electrochemical water treatment (1) is known, having a housing divided into chambers by a semi-permeable cylindrical shell inserted into a perforated frame, a cathode located in one of the chambers along its perimeter made of round steel alloy rods, and an anode of rod electrodes of alloy steel, while the common current path of the cathode is connected to the negative pole of the DC source, and the common current path of the anode is connected to the positive pole of the specified current source.

The disadvantages of the known device are the limited contact area of the cathode and anode with the treated water, the large labor costs in their manufacture and the large weight of the device.

A device for electrochemical treatment of water (2) is also known, having a body divided into chambers by a glass of microporous semipermeable plastic with anode and cathode placed in them, moreover, the cathode is made of profiled alloy steel sheet and covers a glass of microporous semipermeable plastic, and the anode, also made of profiled alloy steel sheet, installed with the coverage of the central rod and placed inside a glass of microporous semipermeable plastic.

The disadvantages of this device are its structural and technological complexity and the high cost of manufacture.

The task to which the claimed utility model is directed is to simplify the design while reducing labor costs in its manufacture without compromising the output parameters (pH and ORP) of the treated water.

The technical result when implementing the inventive utility model is manifested in reducing the cost of its manufacture without deterioration of the output parameters (pH and ORP) of the treated water.

The specified technical result is achieved by the fact that in the inventive device for electrochemical treatment of water, comprising a body of dielectric material and an inner hollow glass of microporous semipermeable plastic, dividing the body into chambers with anode and cathode placed in them, the cathode is made in the form of a group of plates made of corrosion of a metal or alloy, which are radially fixed towards the center on the inner side of the metal shell located along the perimeter of the housing and which is common okopodvod to the cathode, and the anode is also made in the form of a group of corrosion-resistant metal plates located in the radial direction to the cathode and mounted on a central metal rod which is a common current supply to the anode, the cathode and anode plates are made of corrugated titanium sheet, and drain holes from the chambers and terminals for connecting to a current source are located in the bottom of the housing, while the preliminary filtering of the source water from foreign matter is carried out, built-in to the housing cover, polyp pilenovym filter.

The inventive utility model is illustrated and illustrated by the drawings shown in figure 1 (diametrical section of the device). and figure 2 (section of the device along aa).

A device for electrochemical water treatment has a housing 1 and a cover 2 of dielectric material. A hollow cup 3 is installed inside the housing, separating the inner space of the housing 1 into chambers and made of microporous semipermeable plastic with an upper conical part 4. The cathode 5 and anode 6 are installed in the chambers as a group of titanium plates. The group of plates of the cathode 5 is fixed in a metal shell 7, which is connected by a current supply with a negative terminal 8, and the group of plates of the anode 6 is fixed in a metal rod 9, which is a current supply with a positive terminal 10. In the bottom of the housing 1 there are openings 11 and 12 for supplying treated water through nozzles 13 and 14 and adjustable taps (not shown in the drawing) to the consumer. A cartridge of a polypropylene filter 15 is installed in the upper part of the cover 2, which is closed on top by a cover 16 with a pipe 17 for supplying the source water. The watertightness of the joints is ensured by food-grade gaskets (painted black on the drawing).

A device for electrochemical water treatment works as follows. Untreated (source) water through the pipe 17 and the filter 15 is fed into the chambers with the anode 6 and cathode 5. To the terminals 9 and 10 of the current leads are connected, respectively, the positive and negative terminals of the current source. When a current source is turned on under the action of electric field energy between cathode 5 and anode 6, electrochemical activation of water occurs with the formation of catholyte in the cathode chamber with pH = 7-8.5 and redox potential ORP = -300 ... -1200 mV, and in the anode anolyte chamber with pH = 4-6 and ORP = + 300 ... 1000 mV.

After obtaining the specified acid-base and redox properties of the water, the device is disconnected from the current source, and the anolyte and catholyte solutions through the nozzles 13 and 14 and exhaust taps (not shown in the drawing) are poured into the consumer's storage tanks for further intended use.

The calculation of the cost of manufacturing the cathode and anode according to the claimed utility model showed that it is 1.7 times lower than the cost of manufacturing the cathode and anode in an analog device.
