Patent for invention RU No. 2297389, C02F 1/28, op. in 2007). The known device is more versatile than previous technical solutions, but efficiency is achieved due to unjustified complication of the device, which leads to a significant increase in the cost of purified drinking water.

A device for treating a liquid is known, including a venturi tube consisting of a confuser, a neck and a diffuser, hemispherical electrodes located in front of the venturi tube in the confuser region, a current pulse generator connected through a forming arrester to hemispherical electrodes, characterized in that it contains a reflector located in front of hemispherical electrodes on the other side of the venturi, a magnetic field source installed after the venturi, and a filter located after the source field (see patent for utility model RU No. 124260, C02F 1/46, op. in 2013). In this device, water is subjected to high-voltage treatment, which leads to a fundamental change in its chemical and physical properties. This is justified if it is necessary to disinfect water, but is inappropriate for the treatment of drinking water in order to improve its physical and chemical properties.

The closest technical solution to the claimed invention is an installation for the comprehensive purification of drinking water, including a tank with an aeration chamber having an inlet pipe, bottom aerators and a device for supplying water for treatment, a magnetic chamber, an ultraviolet water treatment device, a passive filter and a reservoir of purified water, moreover, the aeration chamber is connected to the magnetic chamber by means of a water supply device, and the ultraviolet water treatment device is installed sequentially behind the magnetically second chamber and associated with a passive filter (see. patent RU №2443638, C02F 9/12, op. 2012). This installation allows you to reduce the energy consumption for water purification when achieving trouble-free operation. However, the process of micromineralization of salts dissolved in water in a known installation is not intensive enough, therefore, a lot of time is required for the complete purification of drinking water.

The installation for drinking water purification according to the first embodiment includes a two-chamber vessel 1 with an inlet pipe 2 connected through a pipe 3 to a pump 4 located in a well or a well 5. A partition 8 is located between the chambers 6 and 7 of the vessel 1 and has an opening in the lower zone for water flows from chamber 7 to chamber 6. A check valve 9 is located in this hole.

In the bottom region of chamber 6 there is a pump 12, on pipeline 1 3 of which the magnetic activator 14 and the pressure gauge 15 are located. The pipe 13 is connected by the output end to a passive filter 16 for mechanical cleaning. The filter 16 is equipped with an outlet pipe 17 for supplying primary purified water to the upper zone of the chamber 7 and a flushing pipe 18. Chamber 7 is a reservoir of purified water with a continuous cycle of its treatment. A pump 19 is located in the bottom region of the chamber 7. The pipe 20 of the pump 19 is designed to supply water for further processing in the ejectors 21 and 22. The ejectors 21 and 22 have the design shown in Figs. 3 and 4. The pump 19 is equipped with a check valve 23, an electrovalve 24 with electric 25 and timer 26.

The end part of the pipeline 20 is connected to the input zones of the ejectors 21 and 22. In the zone of maximum narrowing of the ejectors 21 and 22, the output ends of the air pipe 27 with check valves 28 are located. The air pipe 27 of the air supply system has a vacuum control valve 29. The outlet zone of the ejector 21 is connected by a pipe 30 to the chamber 6. The outlet end of the pipeline 30 is located in the lower zone of the chamber 6. The outlet zone of the ejector 22 is connected by a pipe 31 to the chamber 7.

Figure 2 shows a variant of the installation for purification of drinking water with spaced ejectors 38 and 39. This installation includes a two-chamber tank 1. Between the chambers 6 and 7 of the tank 1 is a partition 8 having an opening in the lower zone for water to flow from chamber 7 to chamber 6 On the pipeline 3 of the pump 4 there is an ejector 38 with a pipe 30, the output end of which is located in the lower zone of the chamber 6. The chamber 7 has a structure similar to that shown in figure 1, characterized by the presence of only one ejector 39 at the output end of the pipeline 20. I line 40, equipped with a vacuum control valve 29, is connected to the narrowest zone of the ejector 38 by a pipe 41 with a check valve 28, and with the narrowest zone of the ejector 39 by a pipe 42.

Twisting vanes 44 are located in the conical part of the confuser 43 at an angle to the direction of the water flow. The output end 45 of the air pipe 27 is located in the zone 46 of the maximum narrowing of the ejector 21 with the formation of a suction chamber 47. In the diffuser 48 of the ejector 21 are longitudinal stabilizers 49.

Figure 5 shows the traditional flow pattern of the water in the system of its supply to the consumer, and figure 6 shows the flow pattern of the water in the described installation, equipped with either ejectors 21 and 22 (figure 1), or an ejector 39 (figure 2).

Installation for drinking water purification works as follows. In the embodiment depicted in FIG. 1, water enters the chamber 6 for primary treatment from the well 5 through the nozzle 2. Its level is controlled by a float sensor 10 connected to the pump 4. Water saturated with air enters the bottom zone of the chamber 6 through the pipeline 30 from the ejector 22. The air supplied with the water by the pipe 30 intensively aerates the water in the chamber 6. Natural water contains mainly iron and manganese compounds as a pollutant, as well as sticky fine suspension of colloidal type, therefore ervoocherednaya need to neutralize and remove these impurities. In chamber 6, water is saturated with oxygen when it comes in contact with air bubbles exiting from the opening of the pipe 30, and metal impurities are oxidized.

The pump 12, designed to pump water from the bottom zone of the chamber 6, feeds it into the complex magnetic field of the magnetic activator 14. Once in the magnetic activator 14, the dipoles of the water’s bipolar nature are subjected to the action of a magnetic field that varies along the course of the water movement, which creates a pulsating effect on dipoles of water. The fine suspension coagulates, the hardness salts are micromineralized and acquire the property of bulk crystallization, and the growth of multiple microcrystals of water-insoluble forms begins. The water treated in the magnetic activator 14 is fed to a passive filter 16 for mechanical cleaning, which may have a different design and a different load. For example, the filter 16, filled with quartz sand, not only cleans water well of mechanical impurities, but also rinses itself well as needed. All solid particles in the water are filtered by a filter 16, and purified water enters the chamber 7.

The water coming from the filter 16 to the circulation chamber 7 is further subjected to intensive aeration using a pipe 31 supplying air-saturated water from the ejector 21 to the chamber 7. Since an opening with a check valve 9 is made in the bottom zone of the tank 1 in the partition 8, the operation of the pump 12 ensures continuous circulation of water from chamber 7 to chamber 6, creating a first circulation loop. The pump 19, located in the bottom zone of the chamber 7, performs different functions: it delivers purified water to the consumer in the pipeline 32, transports water to the ejectors 21 and 22 for additional processing with a cavitation effect, and also provides continuous circulation of water in the chamber 7, creating a second circuit circulation.

Let us consider the effect of cavitation on the example of the operation of the ejector 21. Water is supplied to the ejector 21, treated by aeration in chambers 6 and 7 and exposed to strong alternating magnetic fields in the activator 14. In the ejector 21, water, increasing the flow velocity in the stream over 30 m / s and twisting along the blades 44, provides the appearance of interference zones at the outlet of the diffuser 48. The air entering the rarefaction region of the chamber 47 of the ejector 21 is captured by water flows. Particles of water collide at nodes 50 and continue their broken motion in diffuser 48 until they come in contact with longitudinal stabilizers 49. Water flows are inhibited, cavitation voids are formed, filled with dissolved gases, air continues to mix with water, and radicals form in cavitation and interference energy zones atoms of oxygen and hydrogen. The process of oxidation of the remaining water pollution is multiplied, this is similar to the action of catalysts in chemical processes, oxidation occurs in a split second.

Water purification in the installation occurs without the use of chemical and other reagents. However, bulk crystallization processes are slow. The intensification and acceleration of these processes is facilitated by the multiple passage of water through the magnetic activator 14 and the ejectors 21 and 22. The formation of two water circulation circuits: between the chambers 6 and 7 and inside the chamber 7 ensures a constant circulation of water in the tank 1 and contributes to its complete purification, eliminating stagnation of water during long-term storage, maintaining drinking water in purified condition, regardless of consumption during the day. At the same time, all processes of exposure to water are repeated many times with the circulation of purified water, its quality is significantly increased.

Due to the use of ejectors 21 and 22 connected with the accumulator pipe 32 32, the water in the pipe 32 and in the accumulator 33 does not stagnate, because part of it is constantly sucked into the ejectors 21 and 22, this ensures the reciprocating movement of water between the accumulator 33 and the installation. This process is schematically depicted in FIG. 6. This effect is especially important for the winter conditions of the pipeline 32 in the open air during the transition between the water treatment plant and the room. In the traditional scheme of operation of a house’s water supply system, in order to avoid freezing of the water supply pipeline, it is either buried in the ground below the freezing depth or provided with a heat wire. The above construction avoids freezing of the pipe 32, because the water in it moves continuously, changing the direction of the flow, towards the consumer or towards the ejectors 21 and 22. It is also important that cavitation in the ejectors leads to heating of the water, which eliminates the decrease in its temperature in the absence of analysis.

In the embodiment shown in figure 2, the sequence of exposure to water has a slightly different character. The water is exposed to the ejector 38 immediately after it enters from the well 5, and then enters the chamber 6. The air that is saturated with water after passing through the ejector 38, in addition to the process of oxidation of water pollution, continuously mixes the water in the chamber 6. All other elements of the installation also work as in the case presented in figure 1.

Thus, in the claimed installation, water passes through several stages of continuous repetitive purification, softens, is freed from salts, suspensions, chemical elements, vibrios and pathogenic bacteria, is saturated with oxygen, acquiring consumer-friendly properties.

Experimental studies of the installation for drinking water purification showed that the quality of the drinking water obtained in the installation does not change during the day and does not depend on the time of year and weather conditions.

The claimed installation for drinking water purification provides simplification of the design while reducing energy consumption for water treatment and increasing the reliability of its operation. The combined effect of aeration, magnetic activation and cavitation of water on the molecules of pollutants significantly increases the oxidation potential of all reactions in the installation, contributing to an improvement in the quality of water treatment. The installation is notable for its simplicity of execution, economical operation and maintenance. It can be used in country, rural and cottage options.

Thus, the technical result achieved using the claimed utility model is to improve the purification of drinking water and simplify installation, reduce energy costs for water purification when achieving a trouble-free mode and increase the reliability of its operation.
