Description

The utility model relates to household water purification devices that improve its biological properties by removing carcinogenic and mutagenic substances and gases soluble in it, as well as significantly reduce the content of heavy hydrogen (deuterium) isotopes in it by phase separation of the source water with impurities, by the method crystallization by freezing in a closed volume on clean water and water with impurities and can be used in everyday life, food industry and medicine.

It is known that the reaction of biosystems when exposed to water (H ₂ O) can vary depending on quantitative and qualitative changes in the isotopic composition of H ₂ O. The use of water with an increased concentration of heavy isotopes, in particular deuterium, causes pronounced toxic effects at the body level, limiting the possibility of its use for therapeutic purposes [Kushner DJ, Baker F., Dunstall TG Can. J.Physiol. Pharmacol 1999, Feb. 77 (2): 79-88.]. At the same time, positive biological activity of waters obtained using various technological processes belonging to the category of isotopic lungs with a decrease to one degree or another in comparison with the initial concentration of deuterium [Somlyai G. Let's Defeat Cancer!. Akademiai Kiado, Budapest, 2001.].

The literature data also indicate the biological effectiveness of snow or melt water, expressed in its stimulating effect on the growth and development of plants [Rodimov B.N. The effect of snow water on living organisms. "Agricultural production of Siberia and the Far East." Omsk 4, 1965, pp. 56-57.]. An increase in the concentration of heavy isotopes in the human body leads to a change in the normal course of biochemical processes, which reduces the functionality of the body. As a result, there is a need to increase the content of ¹ H ₂ ¹⁶ O in ordinary drinking water.

The heat exchanger is made in the form of a multi-stage coil located in the upper part of the tank at a height of approximately 1/3 ÷ 2/3 of the tank height at a distance of 2 ÷ 5 cm relative to the upper base of the tank and symmetrically relative to its side surface with a gap that allows volumetric freezing of ice in water around the coil to a size that does not overlap this gap during ice crystallization. The tank is equipped with a heat-insulating cover and seal, the pipeline for draining water with impurities is installed in the very section of the conical bottom of the tank, the pipeline for draining melt water is installed at the bottom of the conical bottom of the tank by 0.5 ÷ 2 cm. The unit is equipped with a fine filter with a drain pipe with a valve and a pump for circulating and pumping melt water under pressure through a fine filter.

However, this installation has large dimensions and weight of the freezing unit with its cooling system, and part of the usable volume in the tank for freezing water is occupied by a heat exchanger made in the form of a coil, which also increases the dimensions of the device and complicates its use in domestic conditions.

A known water purifier for producing thawed drinking water, which includes a zone of water freezing with an annular freezer located in series in a longitudinal vessel, an area for displacing impurities from the ice front and concentration of impurities in the form of a brine, and a zone for transferring water from solid to liquid with an annular heating element (RF patent No. 23412817, IPC C02F 1/22, publ. 20.12.2007). The water purifier has separate nozzles for removing impurities in the form of brine and melt drinking water, located in the lower part of the vessel, and is additionally equipped with a drive unit for moving the rod

frozen water mounted behind the freezer and uncoupling device located in the center of the frozen water rod and made in the form of a pipe. The uncoupling device has an annular cutting part at the inlet, and an expanding profile at the outlet, forming an outlet pipe for removing impurities in the form of a brine.

However, this device is difficult in design, has large dimensions of the freezer, weight, which makes it difficult to use in a domestic environment.

A water purifier is known for producing melt drinking water on an industrial scale from sea water, which includes a water freezing zone with an annular freezer, a zone for displacing impurities from the ice front and a concentration of impurities in the form of brine and a zone of transition of solid state water to sequentially located in one longitudinal vessel. liquid with an annular heating element, separate nozzles for removing impurities in the form of brine and melt drinking water, located in the lower part of the vessel (French Patent No. 2858607, IPC C02F 1/22, publ. 02/11/2005).

impurities and a high content of deuterium (Japan Patent No. 5123668, IPC С02F 1/22, F25В 21/02, publ. 05.21.1993).

However, such an apparatus has one cooling or heating element in the thermoelectric module, which is located on one side of the tank, which does not allow uniformly volume freezing of water in the form of an axisymmetric toroidal body or uniform thawing of ice, which reduces the quality of water purification from harmful impurities and deuterium. In this apparatus, the drainage system of purified (melt) water and contaminated with impurities in the tank does not allow you to quickly prepare the device for operation between cycles and does not ensure its operation in automatic mode, which reduces the usability of the device.
