Description

The invention relates to production methods without deuterium water [C08F11/20, CO2F9/00].

Water in its natural circulation, like a good solvent, absorbs everything that comes in its way and remembers their structures, which are introduced into living organisms. It can contain more than 80 aggressive particles, microbes and viruses, and therefore water is the cause of more than 90% of pathologies. It is not possible to purify water by filtration due to the identical size of many harmful particles with the size of a water molecule. When chlorinated, only living components of water die, such as bacteria, which are converted into three chlorides, which are the strongest carcinogens that form cancer. Even with distillation, it is not possible to perfectly purify water (the smell of borscht from the kitchen can be heard even on the street) because the steam also contains molecules of other substances found in the water. Even in vacuum conditions, physicists still cannot obtain pure water with unique properties. The methods and devices known today cannot solve the problem of water purification, much less turn it into healing water.

The prior art knows a method for producing healing drinking water with a reduced content of deuterium and tritium components by vacuum vaporization at a temperature of 10°C followed by condensation of water vapor [RU2010772]. Methods of water purification are also known [RU2523480, RU2524965, RU2524939, RU2182562, RU2222225, RU2186034, RU 2390993, etc.] electrolysis, foam-fractional, coagulating structuring, filtration, magnetic, vacuum, distillation, ozonation, activating hydrogen , enriched with energy information resources and other methods from suspended particles and the deuterium component. The disadvantage of these methods is that they are complex, expensive and ineffective.

Also known from the prior art is patent RU2084246 - obtaining “living” and “dead” water by electrolysis. As a criticism of the stated solution, the following can be noted: these terms are not scientific, since water has neither an electrical charge, nor alkaline and acidic indicators (acid-base balance), nor smell, nor taste, nor color. They called it “alive”, noticing the healing properties of fresh melt water, and “dead”, i.e. It becomes pathogenic for many reasons due to changes in its chemical composition.

Also known from the prior art is a METHOD FOR WATER PURIFICATION [RU2282596, publ. 08.27.1996] including freezing and thawing, characterized in that freezing is first carried out until 4-5 wt.% of water passes into the solid phase, which is removed, and the remaining part of the water is frozen, subjecting it to hydrodynamic cavitation, until it completely passes into the solid phase, after whereupon the central part of the water is removed in an amount of 4-5 wt.%.

Also known from the prior art is a METHOD FOR PURIFYING WATER BY FREEZING IT AND A DEVICE FOR ITS IMPLEMENTATION [RU2142914, publ. 12/20/1999], including cooling a container with water to freezing temperature, holding, separating deuterium ice, pure ice and residual brine, defrosting pure ice, characterized in that the water is cooled at a ratio of heat flows in the side and end surfaces equal to 50 - 500, maintain it until the product is obtained in one operation in the form of a layer of pure ice along the contour of the container in a volume of 25 - 50% of the initial volume of water, a layer of deuterium ice 0.5 - 4.0 mm thick on both end surfaces and a residual layer located inside the product brine, and to remove deuterium ice from the side surfaces of the product, the container with the product, after removal from the freezer, is kept in thawing mode for a time that is 20 - 40% greater than the thawing time required to separate the product from the container, and to remove deuterium ice, located in the end surfaces of the product, and the residual brine, apply light blows to both end surfaces of the product, remove them and pour out the brine.

Also known from the prior art is a METHOD AND DEVICE FOR WATER PURIFICATION [RU2404131, publ. 20.11.2010]. A method of purifying water by freezing while simultaneously giving it the properties of melt water, including cooling the vessel to freezing temperature, holding it with gradual freezing of the water in the following sequence: first, heavy water freezes on the walls of the vessel, then clean water and, lastly, water with a high salt content in the central part of the vessel, and defrosting ice, characterized in that the entire amount of water is subjected to freezing, then the vessel with frozen water is turned over and thawed, and when the ice is thawed, the first portions of water with a high content of heavy water are drained by gravity into a sealed container through a hole connecting the vessel and a sealed container, and after filling the sealed container, the next portions of melt water fill the vessel to the level of the overflow holes and flow out of the vessel, and the last portions of water with a high salt content, resulting from the melting of the central part of the ice, remain in the vessel.

The main technical problem of these analogues and the prototype is that when implementing these methods, a significant amount of deuterium impurities remains in the water, due to the fact that the purification processes are implemented within a short period of time, as a result of which the likelihood of deuterium impurities getting into the purified water increases.

The objective of the invention is to eliminate the shortcomings of the prototype.

The technical result is to reduce the amount of deuterium impurities in water.

This technical result is achieved due to the fact that the method of water purification, characterized by the fact that initially the water is cooled at a rate of less than 1°C per hour to 0°C, obtaining a piece of ice, after cooling the piece of ice is washed, after washing from the internal volume of the piece of ice The unfrozen part of the water is removed, after which the remaining piece of ice is melted.

In particular, the water is cooled starting from a temperature of +4°C to 0°C.

In particular, a piece of ice is washed under a stream of water.

In particular, the unfrozen part of the water is extracted by breaking a piece of ice.

Implementation of the invention.

The method of water purification, which consists in the production of deuterium-free water, is implemented as follows: the water is frozen at a rate of no more than one degree for one hour, mainly in the range from four to zero degrees - due to which the icy deuterium components float up, suspended in the volume of water . During the freezing process, deuterium water (D2O) freezes (crystallizes) at a temperature of +3.75°C with a natural decrease in specific gravity. After freezing, the formed crystals will float - they will be “pushed” to the surface of the protium component of water, which freezes at 0°C. Deuterium water, being heavy, before crystallization can stick to the bottom and partially to the side walls of the container, and the rest of its crystals suspended in the volume of water will naturally float to the surface of the protium water. Thus, deuterium ice floes will appear on the surface of an ice block (piece) frozen by 60-80%, and in unfrozen 20-40% water all the remaining contents of the water will be concentrated because its molecules, being the smallest, are located in the dendrites of the crystal lattice, displacing all other molecules. By rinsing the surface of an ice block (for example, with a stream of water), we can wash away the deuterium crystals (snowflakes), and after the destruction (splitting) of the ice block, the unfrozen part of the water, with all the substances dissolved in it, will flow out. The resulting pieces of ice, transparent as glass, after melting, form purified water during the implementation of the claimed method.

An example of the implementation of the claimed method.

To create mass production of healing water, a vertical conveyor of a modular design is used, rotating in a freezer with automatic filling of containers with water and unloading of the resulting ice bars while simultaneously washing off deuterium deposits from their surface. An ice block that slips out of the container of the freezer chamber of the installation, after washing off the deuterium water crystals from its surface, falls onto the icebreakers of the mesh conveyor, which passes the unfrozen part of the water into the sewer and transports the ice pieces to the container for thawing.

A freezing installation in the form of a vertical conveyor of a modular design with a given capacity with automatic filling of containers with water and unloading of frozen blocks consists of: two closed chains on which containers for freezing water are hinged with a center of gravity below these hinges, with a heat-insulating closed body in which the circulation cold air obtained by passing it through the evaporators of the freezer compressor. In order to prevent snow from covering the inner surface of the body, containers for freezing water are equipped with lids made entirely from the containers themselves, with cylindrical shapes of larger diameter, with inclined axes for the main containers so that the ice block, when turning the containers 180°, easily slides onto the roof , and then into the outer chamber to wash off deuterium crystals from the surface of the bar.

The declared technical result - reducing the amount of deuterium impurities in water, is achieved due to the fact that the water is cooled at a rate of less than 1 ° C per hour to 0 ° C, due to which deuterium water freezes (crystallizes) quite slowly, which ensures a decrease in the intensity of diffusion processes when the floating of crystals to the surface, thereby reducing the likelihood of residual crystals of deuterium impurities when the temperature reaches 0°C and the formation of a piece of ice. When cooling at a rate of more than 1°C, the processes of crystallization and ascent occur so quickly that the probability increases that a certain amount of deuterium crystals will remain frozen into a piece of ice without having time to form on the surface. Also, the stated technical result is achieved due to the fact that in the embodiment the cooling process begins at a temperature of 4°C, due to the fact that deuterium water freezes at a temperature of +3.75°C, as a result of which increasing the initial water temperature may be impractical from the point of view of increasing the duration of the cleaning process. Also, the stated technical result is achieved due to the fact that the crystals of the deuterium impurity are washed off by washing (for example, using a stream of water), after which the piece of ice is destroyed and the remaining impurities that are not frozen at 0°C are removed.

An example of achieving a technical result.

In 2023, the applicant implemented the claimed method in production, thanks to the gradual freezing of untreated water, it was possible to obtain purified water with a deuterium impurity content of no more than 0.0015%, which is 30-80% better than the technology in which freezing occurred with a decrease in temperature at 5°C per hour. 20-25% better compared to technology in which freezing occurred with a temperature drop of 2°C per hour.
