Disclosure of the essence of the utility model

The technical problem underlying this utility model is to expand the range of products for electrochemical water treatment.

The technical result achieved in the implementation of this utility model is to obtain an anolyte with neutral acidity.

The utility model discloses a portable device for electrochemical treatment of a liquid, containing a container for the treated liquid, a pump and a flow-through electrochemical reactor with two electrode chambers separated by a diaphragm into anode and cathode chambers. Unlike the prototype, the container for the treated fluid is connected through a tube and a pump to the inlet of the cathode chamber of the electrochemical reactor, the outlet of which is connected by a tube to the inlet of the anode chamber, equipped with a unit for the outlet of the treated fluid, while all parts of the device are connected by non-separable connections and mounted on a common platform .

In particular, the treated liquid outlet unit is provided with a check valve.

In particular, the diaphragm of the electrochemical reactor is permeable.

This utility model discloses a device, the components of which are paired or connected at the factory. Preferably, the parts of the device are permanently connected and mounted on a common support plane, such as a platform. This allows you to create mobile, portable products designed for use in everyday life or in industries of various sizes. The container for the treated liquid can be represented by a tank connected to the platform by a permanent connection, for example, by gluing. The pump, in particular, can be hidden inside the platform or mounted on its surface. The electrochemical reactor can be connected to the platform by a permanent connection, for example, by gluing, or can be mounted on the platform by means of detachable connections, for example, fasteners. Said nodes are interconnected by tubes for the movement of the liquid medium. The liquid obtained as a result of the operation of the device can be drained by the user into an arbitrary vessel, for example, a mug or a glass. For ease of use, the product created in accordance with the utility model may have relatively small dimensions, allowing it to be used in the kitchen, bathroom, and living quarters. The device is delivered to the user assembled and does not require additional assembly or disassembly operations. The relative position of the components, their connection and mating lead to a complete independent device, in which the components are deprived of a certain number of degrees of freedom. The exclusion of individual nodes from the design of the claimed device leads to the loss of functionality and the possibility of using it for its intended purpose as a device for electrochemical liquid treatment. It follows from this that the utility model has a constructive and functional unity, that is, it reveals a technical solution related to the device.

The analysis of information from the prior art showed that the present utility model is characterized by essential features, the totality of which is unknown from the patent and scientific and technical literature. This testifies in favor of the compliance of the utility model with the patentability condition "Novelty".

This utility model has been created in accordance with the laws of nature and the knowledge of modern science about them. This testifies in favor of the compliance of the utility model with the patentability condition "Industrial applicability".

This utility model is illustrated with one figure, which shows a diagram of a device for electrochemical treatment of liquid.

Implementation of the utility model

The device for electrochemical water treatment contains a container 1 for treated water and a flow-through electrochemical reactor 2. The container 1 and the reactor 2 are connected by a pumping circuit, which includes a tube for supplying liquid 3 and a pump 4. The anode and cathode chambers 5 and 6 are separated by a diaphragm 7. The diaphragm can be made permeable to gas molecules, but impermeable to liquid molecules. The outlet of the cathode chamber 6 is connected by a tube 8 to the inlet of the anode chamber 5. The unit for the outlet of the treated liquid is equipped with a check valve 9.

The operation of the device is illustrated by the following examples.

Example 1. Container 1 is pre-filled with liquid. The liquid is tap water containing dissolved minerals, in particular table salt. Said liquid is moved by pump 4 to cathode chamber 6 of reactor 2 through tube 3. From chamber 6, liquid then enters anode chamber 5 through tube 8. At the same time, voltage is applied to the anode and cathode of reactor 2. As a result, the liquid stream entering the reactor 2 is subjected to a chemical electrolysis reaction. In the cathode chamber, as a result of electrolysis, hydrogen ions are released from the water contained in the liquid to obtain an alkaline solution of water saturated with hydrogen ions (catholyte). Characteristics of the catholyte: pH 10, redox potential (ORP) -1000 mV. In the anode chamber, respectively, oxygen ions and OH ions are released to obtain a water solution saturated with oxygen ions (anolyte). Anolyte characteristics: pH 2, ORP +1000 mV. Further, the volume of the resulting catholyte in chamber 6 is replaced by a newly flowing liquid from vessel 1, and the catholyte is mixed with the anolyte obtained in chamber 5. In this case, both the liquid again entering chamber 6 and the catholyte transferred to chamber 5 are subjected to electrolysis. in the anode chamber, as a result of the reaction, ions of mineral substances are formed, in particular, active chlorine ions in a relatively small amount. The alkaline catholyte is oxidized in the anode chamber, due to which the anolyte solution becomes neutral. A neutral anolyte solution with active chlorine ions is dispensed to the user through the liquid outlet unit. Characteristics of the neutral anolyte solution: pH 7, ORP +1000 mV.

Example 2 An aqueous solution of table salt acts as a liquid. Due to the electrolysis reaction, a catholyte and an anolyte are formed, which are mixed in the anode chamber due to the replacement of liquid masses in the cathode chamber by newly arriving flows from vessel 1. Characteristics of the catholyte: pH 10, redox potential (ORP) -1000 mV. Anolyte characteristics: pH 2, ORP +1000 mV. The alkaline solution of the catholyte is oxidized in the anode chamber, due to which it becomes neutral. In addition, in the anode chamber, as a result of electrolysis, active chlorine ions are released from table salt. A neutral anolyte solution with active chlorine ions is dispensed to the user through the liquid outlet unit.

Neutral anolyte with pH=7 acidity and active chlorine dissolved in it is indicated for internal and external use as a prophylactic for viral or microbial infections. The active chlorine ions formed as a result of electrolysis act as a disinfectant. At the same time, the neutral environment of the solution makes it possible to exclude changes in the acid-base balance in the body, changes in the intestinal microflora, and the ingress of an alkaline environment onto the skin.

Thus, due to an inexpensive and simple design improvement, a device for electrochemical liquid treatment makes it possible to obtain a neutral solution of oxygenated water (anolyte) with ions of mineral substances that have a beneficial effect on the human body.
