Description

DEVICE FOR ELECTROLYTIC BODY PROCESSING.

The utility model relates to the field of physical water purification by electrolysis and can be used to saturate drinking, medicinal and household water, liquid food products, etc. silver ions to give bactericidal and preservative properties.

Devices for electrochemical treatment and purification of water with a directed change in properties are known from the patent literature, including an electrolyzer with two electrodes and an ultrafiltration diaphragm mounted on dielectric bushings, a flotator with devices for supplying and discharging treated water, a settling tank and separate chambers (see, for example, SU, A.S. 1498716, 1989 and A.S. 1675215, 1991, both of CL C02F1 / 16 and patent RU 2091320 C1, C02F1 / 461, 1997).

These devices are characterized by the relative complexity of the design and high energy consumption, the complexity of maintenance, as the replacement of nodes is performed when the unit is stopped and emptied.

As the closest analogue, a device for electrolytic water treatment was selected, comprising a housing mounted in a tubular ionizer equipped with radial through holes, two electrodes connected to a current source, and the communication pipes are fixed to the outside of the housing, one of which is connected to the cavity of the tubular ionizer described in patent RU 2075450, C 02 F 1/461, 1997.

The known device provides the purification, activation and other selective treatment of water to improve its quality, but does not impart bactericidal and preservative properties.

The task the real utility model is aimed at is the technological universalization of the device by unifying its structural elements, expanding functional capabilities and increasing work productivity.

The required technical result is achieved by the fact that in the known device for electrolytic water treatment, comprising a housing mounted in a tubular ionizer, equipped with radial through holes, two electrodes connected to a current source, and the communication pipes are fixed to the base of the housing from the outside, one of which is connected to by the cavity of the tubular ionizer, at the suggestion of the authors, the housing, the tubular ionizer and the central electrode holder installed in it are made non-conductive, made of polymer 's materials for foods, lamellar silver electrodes are fixed in the longitudinal groove of the central electrode, which radial through-holes of the tubular Ionator soobsh, aetsya receiver via a ring, with the current source electrodes are connected via a reversing switch and the base mounted housing further inlet.

New significant features have expanded the functional and technological capabilities of the device for varying the concentration of soluble silver, operating modes, types of treated water and liquids, and the type of combined operations. At the same time, the device is compact, mobile, easily demountable, and the ionizer electrode holder is a removable interchangeable unit with independently regenerated electrodes. The main advantage over the well-known analogues is that the water is treated on the duct with high productivity.

The implementation of the housing, the tubular ionizer and the central electrode holder installed therein are non-conductive, made of polymer

materials for food, provides electrical, geometric and sanitary isolation of the working volume of the cell to improve the quality of bactericidal treatment of water, safety and productivity.

Fixing the plate silver electrodes inside the longitudinal measuring groove of the central electrode holder of the tubular ionizer axially to the inlet pipe of the water supply for processing allows us to unambiguously solve the multi-parameter problem of dissolving the required amount of silver in the water stream for a specific period of time using the experimental optimization method.

The communication of the longitudinal groove of the central electrode holder with the radial through holes of the tubular ionizer through the annular receiver provides a transverse jet distribution of the prepared solution in the housing and its turbulent mixing before discharge through the outlet pipe to equalize the concentration of silver in the volume of water.

In the annular receiver of the axial channel of the electrode holder there is a damping of the treated water flow, expansion in volume with equalization of pressure, mixing and transverse jet emission through radial holes of a smaller section of the tubular ionizer into the body cavity.

Through an additional inlet pipe at the base of the casing, water is dosed upwardly into the solution from a tubular ionizer in an upward flow, mixed turbulently with it, diluting to a predetermined concentration of silver in water, and drains through the casing outlet pipe.

Therefore, each essential feature is necessary, and their combination in a stable relationship is sufficient to achieve the novelty of quality as the effect of the sum, a new technical result that is not inherent in the attributes separately.

The device for electrolytic water treatment according to this application meets the criteria of patentability, because its serial reproduction is possible in a conventional enterprise, and a comparative analysis of the proposed utility model with identified prior art analogues, from which the technical solution does not explicitly follow for food production and electrical engineers, showed that it is unknown.

The essence of the proposed utility model is illustrated in the drawing, which shows:

figure 1 - General view of the device, a vertical section; figure 2 - electrode holder in axonametry.

The device is powered by an alternating current network (220 V, 50 Hz) through a rectifier 1, which creates a voltage of 3 ... 12 V at unlike silver electrodes 2 (cathode-anode) at a current density of 0.15-5.0 mA / sq. Cm. After reversing the switch 3 automatically, after processing 100 liters of water, with a cycle of 5 ... 10 minutes, the polarity of the electrodes 2 is reversed, and the dissolution of silver ions occurs from the anode, so the metal consumption from both electrodes 2 is almost equal during the operation of this device for electrolytic water treatment.

Both electrodes 2 are made of pure silver (99.99%) in the form of plates (5 mm thick and 35 mm wide), which, through two screws 4, are each symmetrically fixed in the longitudinal groove 5 of the central electrode holder b. The plate electrodes 2 with a reversing switch 3 are connected by means of insulated current leads 7. The electrode holder b and screws 4 are made of non-conductive fluoroplastic approved for contact with food products.

The bottom groove 5 of the electrode holder b open at the top communicates with the annular receiver 8, which is made coaxially with the radial

through holes 9 of the tubular ionizer 10, paired with a Central electrode holder 6.

The tubular ionizer 10 is placed coaxially inside the housing 11, both are made of food-grade polyethylene and are closed from the ends by common PTFE flanges 12, 13, which are externally limited by a supporting metal base 14 and a cover 15, respectively. The cover 15 and the base 14 are fastened together by ties 16 with nuts 17.

The central electrode holder 6 inside the tubular ionizer 10 is fixed with a compression nut 18 mounted in the shroud 15.

In the lower flange 12, fluoroplastic pipes 19, 20 and 21 are mounted, fixed with nuts 22 from the outside, from the side of the base 14. The pipes 19, 20 and 21 are equipped with taps, which are not conventionally shown in the drawing. The central pipe 19 is installed inside the tubular ionizer 10 and serves to supply water for treatment, through the pipe 20 the treated water is discharged from the device, and the pipe 21 is an additional input for technological purposes.

The device operates as follows. For bactericidal treatment with silver, water is supplied purified from impurities and turbidity with the lowest possible content of chlorides and sulfates, since the former sorb silver ions and the latter react chemically with them, forming insoluble compounds, while only a small fraction of free silver ions remain in the water and the effectiveness of its disinfection is reduced.

To prepare silver water for domestic use, drinking tap water is used that meets the requirements of GOST R 51232-98 and SanPiN 2.1.4.559-96 Drinking water. Hygienic requirements for water quality of centralized drinking water supply systems. Quality control.

Between the plate electrodes 2, its anode is saturated with silver ions under the influence of an electric current (electrolysis).

Next, the flow of OOPAOfat water fills the annular receiver 8, while the resulting concentrated silver solution in water (therapeutic water contains 2.0 mg / L) is mixed, and jetted, changing direction and distributed, is poured through the radial holes 9 into the cavity of the housing 11, filling it. In the housing 11, turbulent flows from radial jets from the holes 9 of the tubular ionizer 10 provide additional mixing of the solution in the volume, which merges through the pipe 20.

In the case when drinking water is prepared with a low silver content in the solution (O, 05 ... O, bmg / l), pure water is additionally metered into the housing 11 through the pipe 21 in an additional upward flow, which dilutes the solution with vigorous stirring. It is productive and economical.

Through the pipe 21 conduct sanitary preventive treatment of the device with hygienic liquids.

The consumption of silver from electrodes 2 is O, 05 ... O, 25 grams per 1000 liters of treated water.

Dosing and metering of the introduced silver is carried out at the expense of electricity.

After physical wear of the electrodes 2, the nut 18 is unscrewed and the electrode holder b is removed from the tubular ionizer 10, instead of which the previously combined electrode holder b, previously prepared complete with new electrodes, is mounted, which reduces the auxiliary time and increases the productivity of the work.

Electrolytic treatment of water by anodic dissolution of silver provides it with high bactericidal and preservative properties, because silver causes the death of vegetative forms of bacteria, delays the development of spores, and inhibits the growth of blue-green algae, protozoa and viruses.

The nature of the process of electrolytic dissolution of silver depends both on the conditions of electrolysis and on the composition of water impurities. Suspensions and salts dissolved in water affect the process to the extent that they form dense films on the surface of the silver electrodes 2, making the electrodes poorly soluble, or change the electrochemical reactions.

Silver water is a reliable alternative to chemical chlorination, which, when oxidized, creates carcinogenic by-products generated in increasing quantities due to general environmental pollution. In addition, chlorine as a disinfecting agent has an insignificant period (several hours) of preservative properties.

Silver water retains bactericidal properties for months and even years, which is necessary on river and sea vessels, other autonomous facilities, in arid areas in the absence of central water supply, in areas with an unfavorable or emergency situation.

Studies of prepared drinking water in the proposed device showed that it complies with the requirements of SOLAS-74/96 and the Rules of the Russian Maritime Register of Shipping for the completion of life-saving appliances with a shelf life of 2 years.
