Description

The invention relates to electrochemical treatment of water, used, for example, as a means of regulating acid-base, redox properties, as well as technological aqueous solutions used in agricultural production for presowing treatment of seeds and medicinal purposes in domestic conditions.

A device is known for electrochemical processing of a liquid, comprising a dielectric housing divided by a diaphragm into an anode and a cathode chamber with an anode and a cathode located in them, respectively, connected to a direct current source, while the electrode chambers are connected by a transfer channel, the input of which is located in the cathode chamber at its bottom near the diaphragm, and the output is made in the anode chamber at the upper edge of the electrode, and in the channel at its ends there are mesh electrodes connected to an additional source direct current so that the mesh electrode at the channel inlet is the cathode, and at the output it is the anode, and the negative pole of the additional current source is connected to the positive pole of the main current, and the transfer channel is made in the device casing (SU, copyright certificate No. 1634643, M. cl. 5 C02F 1/46).

The disadvantages of the known device are the limited contact area of the electrodes with the liquid being treated, a significant distance between the cathode and the anode, leading to increased energy consumption. This does not provide the specified parameters of catholyte (pH and mV) and anolyte. Reducing the distance between the electrodes leads to a decrease in the volume of the processed fluid.

A portable device for the electrochemical treatment of liquids is also known, including a housing divided by a diaphragm into a closed inner and open outer chambers with anode and cathode located in them, while the housing is cylindrical, the diaphragm is installed in its lower part, the anode is perforated and mounted above the diaphragm in closed chamber, the cathode is placed in an open chamber under the diaphragm and mounted with the possibility of vertical movement, and the working surfaces of the electrodes and the diaphragm are made in de truncated cones with an angle of 60 ... 120 °, and the anode is formed as a ring at the apex of the helix (SU, Inventor's Certificate №1611881, M. cl. 5 C02F 1/46).

The disadvantages of the known device include the limited contact area of the electrodes with the processed fluid. This leads to a significant waste of electrical energy and does not provide the specified parameters of anolyte and catholyte.

A device for the electrochemical treatment of water, comprising a housing divided by a semi-permeable cylindrical shell into chambers with anode and cathode located in them, the cathode is made of round steel rods connected by a current conductor installed around the perimeter of the chamber, consisting of a perforated frame, on the inner wall of which is fixed a semipermeable cylindrical shell made of microporous plastic, an anode of rod electrodes made of alloy steel is placed in the chamber, connected by a common conductor (RU, patent for invention No. 2281916 C1 IPC C02F 1/46).

The disadvantages of this device include the difficulty of manufacturing, the limited availability of anode rods for electric current flow, the use of alloyed steel subject to electrochemical corrosion as the electrode material, as a result of which harmful chemical elements can form in activated water.

This design of the device is accepted by us as the closest analogue.

The problem to which the claimed invention is directed is to increase the contact area of the electrodes with the liquid being treated, and to prevent the formation of harmful chemical elements in electroactivated water.

The technical result is a reduction in energy consumption to obtain a given activation potential of the source liquid (water), obtaining environmentally friendly anolyte and catholyte.

The specified technical result is achieved by the fact that in a known installation for increasing the biological activity of water, comprising a housing divided by a semi-permeable cylindrical shell into an anode and cathode chambers with anode and cathode located in them, while the casing and the chamber inside it are made of a cylindrical shape made of dielectric material resistant to electrochemical corrosion, the anode and cathode are made of titanium sheet, which is given a zigzag shape and inscribed in the internal cavity of the housing and the anode chambers inside it, while the zigzag parameters provide directional movement of electrons from the anode to the cathode, the anode chamber inside the case has perforation in the side wall facing the cathode, the semi-permeable shell can be made of microporous plastic or tarpaulin mounted without a gap to the side wall of the anode chamber, supply of positive and negative potential to the electrodes is provided from a diode connected to an electric network with a voltage of 220 volts.

The invention is illustrated by drawings.

Figure 1 shows the installation to increase biological activity is a diametrical section.

Figure 2 is the same, plan view with the cover removed.

Installation for increasing the biological activity of water includes a cylindrical dielectric housing 1 made of a material resistant to electrochemical corrosion. Inside the housing 1 is placed an anode chamber 2 of a cylindrical shape made of a dielectric material resistant to electrochemical corrosion. The anode chamber 2 on the outside has a semi-permeable cylindrical shell 3 made of microporous plastic or tarpaulin according to GOST 15530-93. An electrode 4 with a positive potential is made in the anode chamber 2, made of titanium sheet, which is given a zigzag shape inscribed in the inner cavity of the anode chamber 2. On top of the casing is closed a lid 5 of dielectric material. A diode 6 is mounted in the cover 5, which provides the conversion of alternating current to direct current.

An electrode 7 with a negative potential made of titanium sheet, which is given a zigzag shape, providing the maximum area of interaction of the electric potential with water, is installed in the internal cavities of the housing 1 forming the cathode chamber. The anode chamber 2 from the side of the electrode 7 in the wall has a perforation 8, which ensures the passage of electrons 9 from the electrode 4 to the electrode 7. The anode chamber 2 has a bottom 10 for the possibility of extracting anolyte of water with a positively charged potential from the housing 1.

Installation to increase the biological activity of water works as follows.

Before starting work, the housing 1 and the anode chamber 2 are filled with water to be activated.

The housing 1 is closed by a cover 5, on which electrodes 4, 7 are fixed. An alternating electric current is supplied to the diode 6, and electroactivation begins.

When a direct electric current flows through water, the entry of electrons into the water at the cathode and the removal of electrons from the water at the anode is accompanied by electrochemical reactions on the surface of the cathode and the anode, as a result of which new substances are formed, the entire system of intermolecular influences changes, including the structure of water as a solvent .

During anodic treatment, the acidity of water increases, the redox potential increases due to the formation of stable and unstable acids (sulfuric, hydrochloric, hypochlorous, supra sulfuric), as well as hydrogen peroxide, peroxosulphates, peroxocarbonates, oxygen-containing chlorine compounds and various intermediate compounds that occur during spontaneous decay and interaction of the named substances. Also, as a result of anodic electrical processing, the surface tension slightly decreases, the electrical conductivity increases, the content of dissolved chlorine, oxygen increases, the concentration of hydrogen, nitrogen decreases, and the structure of water changes.

A quantitative characteristic of the acidity or alkalinity of water is a hydrogen pH, which is determined by the activity of hydrogen ions or the ratio of the concentration of hydroxonium ions H 3 O + and hydroxyl OH - . In neutral water, pH = 7, which corresponds to the equality of the concentrations of these ions.

The redox potential (ORP) characterizes the activity of electrons in an aqueous solution (water). An increase in the oxidation potential is due to a decrease in the activity of electrons in solution, and a decrease in the oxidation potential is determined by an increase in the activity of electrons. The nature of the ORP is primarily due to the quantum-mechanical characteristics of the atoms of the elementary electrochemical system - “electrode - solution”.

In activated water, a significant change in the structural components of the interionic energy interaction occurs, i.e. active ion concentration changes due to changes in activity coefficients.

The anolyte obtained as a result of electrical activation has antimicrobial activity; it is used for sterilization, disinfection, and destruction of pathogenic microbes and pests.

The main processes during unipolar electroactivation during cathodic treatment in chamber 1 are electrolytic, as well as heterophase and liquid phase electrocatolytic reduction in the cathode chamber of the electrochemical reactor of water and the substances contained therein. During cathodic treatment, water is saturated for a fraction of a second with highly active reducing agents: OH - , H 2 O 2 - , HO 2 - , O 2 - , which leads to the formation of insoluble hydroxides of heavy metals

Figure 00000001
.

In addition, in the cathode chamber there is a direct electrolytic reduction on the electrode surface, as well as electrocatolytic reduction in the volume of water with the participation of transfer catalysts and hydrated electrons, multiply charged heavy metal cations:

Figure 00000002
, eg,
Figure 00000003
;
Figure 00000004
;

Figure 00000005

These processes reduce the toxicity of water due to the presence of heavy metal ions, by translating them into natural stability, a biologically inactive form of existence in nature.

As a result of the cathodic treatment, any water acquires an alkaline reaction due to the conversion of some of the dissolved salts to hydroxides. Its redox potential decreases sharply, the surface tension decreases, the content of dissolved oxygen and nitrogen decreases, the concentration of hydrogen, free hydroxyl groups increases, the electrical conductivity decreases, and the structure of not only ion hydration shells, but also the free volume of water changes.

The formation of readily soluble sodium and potassium hydroxides and the increase in pH result in a shift in carbon dioxide equilibrium with the formation of sparingly soluble calcium and magnesium carbonates from the usually soluble compounds of these metals - hydrocarbonates, chlorides, sulfates. Ions of heavy metals and iron are almost completely converted into insoluble hydroxides.

The listed changes in the composition and structure of water increase its biological activity - seed germination is increased, their germination energy is increased, and the growth and development strength of plants and fruits is increased.

It was experimentally established that when using the installation to increase the biological activity of water upon receipt of the anolyte, the redox potential (ORP) of water reaches 900 ... 1000 mV, and the pH value is 3.5 ... 4.0 units. pH Upon receipt of the catholyte, the ORP of water reaches -1000 ... -1100 mV, and the pH is up to 10.5 units. pH
