Description

Application area

The invention relates to the field of applied electrochemistry, in particular to methods for the electrochemical preparation of electrochemically activated disinfectant solutions that can be used as a disinfectant, and are used for disinfection, pre-sterilization cleaning and sterilization of various objects, including in the food industry, medicine and cosmetology.

State of the art

Currently, in medicine and in various fields of technology, in particular in the field of water treatment, water disinfecting solutions containing inorganic compounds, in particular compounds of active chlorine obtained chemically, are widely used [see, for example, L. Kulsky. and other "Technology of natural water purification", Kiev, Higher school, 1981, p.22-25].

A disadvantage of the known solutions is the possibility of the formation of chlorination by-products in the presence of organic contaminants, high corrosivity, increased safety requirements, the presence of a large amount of ballast substances in the working solution.

Such disadvantages are deprived of electrochemical methods for producing such solutions, which simplify the preparation process and reduce the number of reagents.

The closest in technical essence and the achieved result is a method and installation for producing disinfecting and washing solutions by electrochemical treatment of alkali metal chloride solutions with a concentration of up to 5 g / l, obtained by mixing drinking water with a saturated solution of alkali metal chloride. In a known solution, the alkali metal chloride solution is supplied in parallel streams to the anode and cathode chambers of the electrochemical reactor, and after processing it is supplied to the consumer [see “Electrochemical activation: history, condition. Prospects ”, M., Academy of Medical and Technical Sciences of the Russian Federation, ed. VNIIIMT, 1999, pp. 36-38]. In this case, the solution treated in the anode chamber is a disinfectant, and the solution processed in the cathode chamber is a detergent. Processing is carried out in diaphragm flow modular elements FEM-3, the length of which significantly exceeds the interelectrode distance [see ibid., pp. 24-26]. This method is selected by the authors as a prototype.

The use of a known technical solution allows to obtain solutions with a relatively high disinfecting and sterilizing ability.

A disadvantage of the known solution is the low pH of the solution obtained from the anode chamber (anolyte), which leads to its increased corrosion activity, and also requires increased safety measures when used. The low pH of the anolyte is explained by the presence of dissolved chlorine, which, evaporating from the solution in free form, is a toxic substance.

In addition, the known electroactivated disinfectant solution contains sodium chloride in an amount greater than the content of functionally useful oxidants. This also leads to increased corrosion activity of the oxidant solution. The antimicrobial activity of such solutions rapidly decreases over time, due to the acceleration of the mutual neutralization of chlorine-oxygen and hydroperoxide compounds in the oxidant solution with an increase in its total mineralization. The elimination of this drawback leads to a complication of plant diagrams and to an increase in the cost of their operation.

The known installation contains at least one electrochemical diaphragm cell made of coaxially mounted cylindrical external and internal electrodes and placed between them coaxially finely porous diaphragm made of zirconium oxide ceramics, dividing the interelectrode distance into the anode and cathode chambers. The chambers have an inlet and an outlet, which are connected respectively to the lines for supplying the electrolyte to the chambers and the lines for outputting the treated electrolyte from the chambers, a unit for preparing the initial electrolyte solution, made in the form of a container with a concentrated solution of alkali metal chloride and a dosing device. The metering device mixes the concentrated chloride solution with fresh water, after which the resulting stock solution is sent for processing to the cell chambers.

The well-known installation is made on a modular basis, which makes it easy to assemble installations of various capacities. The disadvantages of the installation is that concentrated alkaline metal chloride solutions are used as the initial salt solutions, which requires precise dosing of the reagents using a metering pump. In addition, the known installation is equipped with a relatively large number of control devices and systems that ensure uniform removal of cathode deposits in all cells during periodic washing with an acid solution.

As follows from the above, the disadvantages of the known solutions can be eliminated by replacing chlorine-containing disinfectants with other ones that do not contain chlorine. So, for example, it is known that peroxo compounds, in particular sodium peroxocarbonate, have a disinfecting, bactericidal effect [see Chemical Encyclopedia, M., Publishing House "Big Russian Encyclopedia", 1992, v.3, p.184].

However, the known method and installation cannot be applied to obtain disinfectant solutions that do not contain chlorine, in particular to obtain solutions of alkali metal peroxocarbonates.

Disclosure of invention

The technical result achieved by using the present invention is to expand the functionality of the method, reduce the cost of its implementation and provide the possibility of obtaining electrochemically activated disinfectant solutions that do not contain chlorine, as well as the simultaneous preparation of solutions with increased biological activity and extracting ability.

The technical result is also to simplify the installation, expand its functionality and reduce labor costs for its maintenance.

These technical results are achieved by the fact that the method of producing an electrochemically activated disinfectant solution is carried out by electrolysis of the initial electrolyte solution in a diaphragm electrochemical reactor, the electrodes of which are separated by a finely porous diaphragm into the anode and cathode chambers, the length of the electrode chambers being longer than the interelectrode distance. The initial electrolyte solution is fed into the anode chamber. The electrochemically activated disinfectant solution is removed from the anode chamber by supplying an auxiliary electrolyte to the cathode chamber of the same reactor and the output of the processed auxiliary electrolyte from the cathode chamber. Fresh (drinking) water with a mineralization of 0.1-0.5 g / l saturated with carbon dioxide to a concentration of 0.1-0.5 g / l is used as the initial electrolyte solution, and the supply of the initial electrolyte solution to the anode chamber and the supply auxiliary electrolyte in the cathode chamber is carried out countercurrent. The method is carried out with the length of the electrode chambers 100-1000 times greater than the interelectrode distance.

As an auxiliary electrolyte, either the initial solution is used - fresh (drinking) water with a mineralization of 0.1-0.5 g / l, saturated with carbon dioxide to a concentration of 0.1-0.5 g / l, or a solution of sodium carbonate with a concentration of 0, 1-0.5 g / l, or a solution of sulfuric acid with a concentration of 0.1-0.2 g / l, or a solution of sodium hydroxide with a concentration of 0.1-0.2 g / l, or a solution of sodium sulfate with a concentration of 0.1- 0.2 g / l

The use of fresh water as an initial electrolyte solution with a mineralization of 0.1-0.5 g / l saturated with carbon dioxide to a concentration of 0.1-0.5 g / l allows one to obtain an electrochemically activated disinfectant peroxycarbonate solution with a disinfecting ability comparable to with similar properties of a 3% hydrogen peroxide solution, which allows its effective use in the food industry and cosmetology. The use of fresh drinking water with a concentration of less than 0.1 g / l significantly increases the energy consumption for the process, as the conductivity of the initial solution and the number of ions catalyzing the formation of peroxocarbonates sharply decrease. An increase in the concentration of fresh water above 0.5 g / l leads to a decrease in the disinfecting ability of the resulting solution, since the probability of destruction of disinfecting peroxocarbonate compounds by anode electrolysis products increases.

The saturation of water with carbon dioxide is necessary to ensure the possibility of obtaining disinfecting agents in solution - peroxo compounds of carbonic acid. At lower concentrations, the disinfecting ability of the solution decreases, at large concentrations, the gas phase content in the solution increases significantly, there is a likelihood of a two-phase system having a significant volume of gas bubbles, which leads to an imbalance in the electrolysis process, increased energy consumption and lower quality of the resulting products.

In applied electrochemistry, there is a known method for producing peroxo-carbonic acid by electrolysis of a solution containing potassium thiocyanate by sparging carbon dioxide through a solution. The pressure of carbon dioxide is maintained at a level of 2-23 atm and the process is conducted in a diaphragmless electrolyzer at an anode current density of 0.05-0.5 A / sq. Cm [see USSR author's certificate No. 1815262, С07С 407/00, 1993]. Although this process does not require low temperatures, it is laborious and requires the consumption of chemicals and energy costs for maintaining pressure and sparging of carbon dioxide. In addition, this process is carried out in a diaphragmless electrolyzer, which requires additional technological operations to isolate the target product and prevent the loss of potassium thiocyanate. Obviously, the known recommendations are not used in the proposed solution.

The method according to the invention is implemented in a diaphragm electrochemical reactor, into the cathode chamber of which an auxiliary electrolyte is supplied countercurrently. The use of a countercurrent makes it possible to achieve the highest possible degrees for oxidation in the anode chamber and for reduction in the cathode chamber.

When used as an auxiliary electrolyte, the initial solution, i.e. drinking water with a salinity of 0.1-0.5 g / l, saturated with carbon dioxide to a concentration of 0.1-0.5 g / l, it is possible to obtain a new product - catholyte carbonated drinking water, that is, the functionality of the method is expanded. When the concentration of dissolved salts and carbon dioxide in such an auxiliary electrolyte is less than 0.1 g / l, the conductivity in the cathode chamber decreases, which leads to an increase in energy consumption, and with an increase in the concentration of dissolved salts and carbon dioxide over 0.5 g / l, there are no proportional changes redox properties of the obtained electrochemically activated catholyte.

Use as an auxiliary electrolyte a solution of sodium carbonate with a concentration of 0.1-0.5 g / l, or a solution of sulfuric acid with a concentration of 0.1-0.2 g / l, or a solution of sodium hydroxide with a concentration of 0.1-0.2 g / l, or a sodium sulfate solution with a concentration of 0.1-0.2 g / l allows you to expand the range of products obtained depending on the conditions of the problem and obtain the following types of electrochemically activated anolytes, respectively: anolyte with an increased content of sodium peroxocarbonate, anolyte with a certain amount of ernoy acid and low pH, anolyte with a high content of hydrogen peroxide, the anolyte with a low content persulfuric acid and a pH close to neutral anolyte the content of a certain amount of sodium perchlorate. These types of antimicrobial solutions can be used to inhibit the microbiological activity of various types of microorganisms depending on the physicochemical properties and chemical composition of their environment. When the concentration of dissolved salts in auxiliary electrolytes is less than 0.1 g / l, the conductivity in the cathode chamber decreases, which leads to an increase in energy consumption, and an increase in the concentration of dissolved salts above 0.2 g / l does not change the redox properties of the obtained electrochemically activated catholyte , but increases its salinity and shortens its shelf life.

The method is carried out with the length of the electrode chambers 100-1000 times greater than the interelectrode distance. This allows you to distribute the volume of the treated solution in the form of a flat stream of relatively small thickness, relatively small width and extended length, which leads to the intensification of oxidative reactions at the anode, reduction reactions at the cathode and reduces the destruction of the target products due to reactions that occur in the volume of the electrolyte with stirring. With a length of less than 100 interelectrode distances, it is not possible to achieve the required degree of conversion, and with a length of more than 1000 interelectrode distances, the costs of ensuring hydraulic flow stability sharply increase. Ensuring a significant length of the lengths of the chambers is carried out by sequential hydraulic connection of the electrode chambers of the same cells.

The technical result achieved using the present invention is also to simplify installation, expand its functionality and reduce labor costs for its maintenance.

This is achieved by the fact that the installation for producing an electrochemically activated disinfectant solution contains a diaphragm electrochemical reactor made of one or more electrochemical cells with coaxial cylindrical electrodes and a finely porous diaphragm installed between the electrodes, dividing the interelectrode space of the cell into the anode and cathode chambers, the length of which is longer than the interelectrode distance , with devices for input and output of the processed electrolyte into the anode and cathode the cell chamber located at the ends of the cell or near its ends, a fresh water supply line and an electrochemically activated disinfectant solution drain line connected to a device for withdrawing from the anode chamber, a treated electrolyte drain line connected to a device for withdrawing from the cathode chamber and a cooking unit stock solution.

Devices for introducing electrolyte into the anode and cathode chambers and, accordingly, devices for removing electrolyte from the anode and cathode chambers are located at opposite ends of the cell. This allows for the processing of solutions in the anode and cathode chambers countercurrent, which extends the functionality of the installation and allows you to get the range of target products at the highest possible in electrochemical systems with diluted electrolytes oxidizing or reducing environmental conditions.

The cell or cells of the reactor are made with a length of 100-1000 times the interelectrode distance. This allows you to effectively implement the method and obtain disinfectant solutions that do not contain active chlorine. Ensuring the length can be carried out due to the serial hydraulic connection of the chambers of the same type of cells, which will ensure the necessary installation performance and reduce the labor costs for its repair. Reducing the length of less than 100 does not allow to provide the necessary degree of processing and to obtain solutions with desired properties, and an increase of over 1000 leads to an increase in hydraulic resistance and an increase in the cost of operating the installation.

The unit for preparing the initial solution is made in the form of a saturator connected to a carbon dioxide supply source. This embodiment allows you to get the initial electrolyte solution of the desired composition from drinking water and carbon dioxide. It also allows you to automate the process of preparing the initial solution and simplify the installation by eliminating the need to control the amount of concentrated solution introduced.

The apparatus for producing an electrochemically activated disinfectant solution may further comprise an auxiliary electrolyte capacity connected to a device for introducing electrolyte into the cathode chamber. This will expand the functionality of the installation and provide solutions of various compositions and purposes.

Brief Description of the Drawings

The method can be implemented using the settings shown in figures 1 and 2.

Installation for implementing the method (figure 1) contains an electrochemical reactor 1 made of one or more electrochemical modular diaphragm cells, the same electrode chambers of which are connected hydraulically in series. The electrochemical cells are separated by a diaphragm 2 into anode 3 and cathode 4 cameras. The input of the anode chamber 3 is connected to the supply line of the initial solution 5. The input of the cathode chamber 4 is also connected to the supply line of the initial solution 5 by the supply line of the solution to the cathode chamber 6. The output of the anode chamber 3 is connected to the discharge line of the electrochemically activated disinfectant solution 7, and the output of the cathode chamber 4 is connected by a catholyte discharge line 8. The installation comprises a fresh (drinking) water supply line 9 on which a saturator 10 is installed, into which carbon dioxide is supplied from a separate unit (not shown in the figure).

The installation may contain additional capacity for auxiliary electrolyte 11 (figure 2). In this case, the line 6 connected to the input of the cathode chamber 4 is hydraulically connected to the auxiliary electrolyte supply line 12. In this case, a locking device 13 is installed on the line 6 before connecting to the line 12, and in series on the line 12 between the tank 11 and the connection with line 6 a pump 14 and a locking device 15 are installed.

The method is carried out and the installation works as follows. Through the cathodic 4 and anode 3 chambers of the reactor 1, countercurrent water is passed from the saturator 10, where the process of its aeration is carried out. A voltage is applied to the electrodes of the reactor, which ensures the flow of the required current (in steady state, from 3 to 10 A). After the unit reaches the mode (current stabilization at anolyte flow rate from 5 to 25 liters per hour and catholyte consumption from 10 to 60 liters per hour), an electrochemically activated disinfectant solution is discharged from line 6 from the anode chamber 3, and line 7 from the cathode chamber 4 catholyte is removed - an extracting, biologically active solution.

On line 12 into the cathode chamber 4 in countercurrent, relative to the direction of flow in the anode chamber 3, with the help of the pump 14 can supply auxiliary electrolyte from the tank 11 (figure 2). The electrolysis products are removed as described above.

In the anode chamber, reactions of oxidation of water and products of electrochemical oxidation reactions proceed:

2H ₂ O-4e → 4H ⁺ + O ₂ ; 2H ₂ O-2e → 2H ⁺ + H ₂ O ₂ ; O ₂ + H ₂ O-2e → O ₃ + 2H ⁺ ;

3H ₂ O-6e → O ₃ + 6H ⁺ ; H ₂ Oe → HO ^• + H ⁺ ; H ₂ O ₂ → HO ₂ ^• + H ⁺ ;

H ₂ O-2e → 2H ⁺ + O ^• ; H ₂ O → H ⁺ + OH ^• .

Oxidation in the presence of catalysts, which are the products of anodic electrochemical reactions, also undergoes carbon dioxide dissolved in water, turning into a carbonic acid:

2H ₂ CO ₃ ^2- 2e → C ₂ O ₆ ^{2- +} 4H +.

At neutral or slightly alkaline pH values, succinic acid (HOOC-O-O-COOH) forms salts as a result of the replacement of hydrogen ions by alkali metal ions.

Sodium salt of diacetic acid (sodium carbonate or sodium percarbonate), when reacted with water, undergo hydrolysis:

Na ₂ C ₂ O ₆ + 2H ₂ O → 2NaHCO ₃ + H ₂ O ₂ .

With decreasing pH of the anolyte, Na ₂ C ₂ O ₆ decomposes into H ₂ O ₂ and CO ₂ .

For mono-angular acid (НООС-O-О-Н), not only medium (as for suprahedral), but also acid salts are known. Those and others can be obtained by interaction with carbon dioxide peroxides or hydroperoxides of alkali metals, which are also formed in the process of anodic oxidation reactions, according to the schemes:

Me ₂ O ₂ + CO ₂ = Me ₂ CO ₄ or MeOO + CO ₂ = MeHCO ₄ .

By properties, they are similar to salts of perhydric acid. Also known are the products of the addition of hydrogen peroxide to carbonates, for example, “persol” Na ₂ CO ₃ · 1.5H ₂ O ₂ · H ₂ O. It is not clear to what extent peroxide derivatives of carbonic acid are addition products or true salts of carbonic acids. Potassium carbonate (K ₂ C ₂ O ₆ ) is sometimes used as an oxidizing agent in chemical analyzes. He immediately liberates free iodine from a neutral Kl solution.

The resulting antimicrobial solution has the following characteristics: the content of peroxy compounds is from 3 to 30 mg / l, the redox potential is in the range from +500 to +800 mV relative to the silver chloride reference electrode, the total concentration of dissolved electrolytes is from 0.1 to 1.0 g / l

At the cathode, a water reduction reaction and related electrochemical reactions involving the reduction products take place:

2H ₂ O + 2e → H ₂ + 2OH ^- ; O ₂ + e → O ₂ ^- ; О ₂ + H ₂ O + 2е → HO ₂ ^- + ОН ^- ;

HO ₂ ^- + H ₂ O + e → HO ^• + 2OH ^- ; e _cathode + H ₂ O → e _aq ; H ₂ O + e _aq → H ^• + OH ^- ;

СО ₃ ^2- + 2Н ₂ O + 2е → HCO ₂ ^- + 3ОН ^- ; 2SO ₄ ^2- + 5Н ₂ O + 8е → S ₂ O ₃ ^2- + 10ОН ^- ;

SO ₄ ^2- + 4Н ₂ O + 2е → SO ₃ ^2- + 2ОН ^- .

The catholyte containing the above compounds has a high extraction ability and high biological activity due to the low value of the redox potential.

Example 1. A method of obtaining an electrochemically activated disinfectant solution was carried out in the installation, assembled according to the scheme shown in figure 1

An initial solution of various compositions obtained from drinking water by mineralization of 0.1 and 0.5 g / l, respectively, was supplied to the anode chamber 3 through line 5 with a flow rate of 10 l / h. The solution contained carbon dioxide in an amount of 0.1 and 0.5 g / l, respectively. The same solution was supplied to the cathode chamber 4 in countercurrent with respect to the direction of flow in the anode chamber. The interelectrode space of the cells was 2000 and 1600 mm, respectively. A disinfecting solution was withdrawn along line 6 from the anode chamber 3, and catholyte - extracting solution was withdrawn from the cathode chamber 4 along line 7.
