Description

The invention relates to the field of water purification while giving it the properties of melt water and can be used in food, pharmaceutical, medical industry and in everyday life.

A known method of water purification [Method of water purification. Patent 2282596, Bondarenko V.A., Kasperovich V.L., Mezhueva L.V. Application 2004136101/15. Russia. IPC С02F 9/08. Claim 2004.12.09., Publ. 2006.08.27], in which the source water is frozen until 4-5 wt.% Water is transferred to the solid phase and which is then removed.

The disadvantage of this method is the need for time control operations of freezing and removing ice.

Closest to the proposed method is a method of purifying water [Method of purifying water by freezing it and a device for its implementation. Patent 2142914, Stakhiev Yu.M., Russia, IPC C02F 1/22, application 98108077/12. Claim 1998.04.24, publ. 1999.12.20], in which the deuterium ice is removed from the outer side surfaces by holding the ice vessel at room temperature for a time that is 20 ... 40% longer than the thawing time required to separate the ice from the tank. Then the remaining ice is removed from the vessel in which the heavy water remains. A layer of ice is removed from the ends of the remaining ice floe, the residual brine is poured out. The remaining ice is melted and clear water is obtained.

The disadvantage of this method is the need for time control operations of freezing, thawing and removing ice.

The objective of the invention is to simplify the process of separation of water.

The operation of the proposed device is based on the phenomenon of phased freezing of water: first, heavy water freezes on the walls of the vessel, then clean water, and lastly, water with a high salt content freezes in the central part of the vessel. When ice is thawed at room temperature, melting occurs in the same sequence, i.e. melting ice goes from the surface to the center. Separation of water into components occurs due to its successive pouring into a closed container and due to overflow.

The following water purification device is proposed. Water is poured into a vessel (1), which has a lid (2) of the filler neck (3). A sealed container (4) is attached to the lid (2), which is connected to the vessel (1) by an opening (5). One or more overflow openings (6) are made in the vessel, which are located below the opening (5).

Water is poured into the vessel (1) to the level of overflow openings (6) or below them. The vessel (1) with water is frozen. Then the vessel (1) with frozen water is turned over and subjected to thawing.

The first portions of water resulting from the melting of the surface layer of ice are drained by gravity into a sealed container (4) through the hole (5). After the surface layer of ice has melted, the remaining ice is freed from contact with the walls of the vessel (1) and lowers down to touch the vessel (1). After filling the sealed container (4), next portions of pure melt water fill the gap between the ice floe and the walls of the vessel (1), the water level rises to the overflow holes (6) and clean melt water flows out. Thus, water is separated: heavy water is collected in the sealed container (6), water with a high salt content remains in the vessel (1) and pure melt water is collected outside the vessel (1).

It is proposed to carry out a sealed container (4) with a volume of 3 ... 90% of the volume of the vessel (1), overflow holes (6) should be performed at a height corresponding to 60 ... 90% of the volume of the vessel (1).

This device can also be used to divide water into 2 parts:

- with the volume of the sealed container (4) 3 ... 6% of the volume of the vessel (1) and the minimum difference in the levels of the overflow holes (6) and the hole (5) connecting the vessel (1) and the sealed container (4), separation will occur in heavy water and water with a reduced content;

- with the volume of the sealed container (4) 60 ... 90% of the volume of the vessel (1) and the minimum difference in the levels of the overflow holes (6) and the hole (5) connecting the vessel (1) and the sealed container (4), the separation will occur in clean water with heavy water and water with high salt content.

The proposed device allows the separation of water without time control and without performing manual operations both in the process of freezing water and in the process of thawing ice.

The proposed device can also be used to increase the concentration of solutions.

To verify the proposed device, a series of experiments was conducted with various shapes and volumes of the vessel (1), the size and location of overflow openings (6) and a sealed container (4). The modes of freezing and thawing were checked. The experiments were carried out with tap and artesian water. Qualitative results were obtained on water treatment in a wide range of design and technological parameters. Water with improved organoleptic properties was obtained stably.
