Description

The invention relates to ice formation and can be used in sports and construction when creating artificial ice rinks and their varieties - speed skating tracks, hockey rinks, etc.

Known traditional systems for the preparation of water for ice arenas, in which the main unit of deep purification and demineralization of water are membrane units of reverse osmosis (see, for example: http://www.osmos.ru/prom/vodopodgotovka_info/statji/vodopodgotovka_ledovye_areny.html). Such schemes are characterized by high technological complexity, energy consumption and sensitivity to even minor deviations from the set parameters.

There is a known system for making ice using degassed water, combining a method of making ice for recreational use and a device for making ice for recreational use, said device comprising a device for degassing water having an inlet for water and an outlet for (RU2011136664A), water, when Thereby, the water inlet feeds water containing dissolved gas, and the water outlet discharges degassed water, the gas being removed by vacuum suction through a membrane filter. This system is actually a variation of the traditional water treatment system with its inherent disadvantages.

Known water treatment system for ice rinks REALice (see: http://h2ovortex.ru/products/realice). Ice covered with water prepared using the REALice system freezes in thin layers that envelop each other, thus making the ice much stronger and better than usual. Ice freezes faster and remains at higher temperatures, which leads to energy savings - you can increase the temperature of the ice used to 1-2 ° C. You can also use water below 20 ° C.

A vortex generator is at the heart of the REALice water treatment system. Energy in systems is generated by the formation of a vortex by the flow of water. Water treated with Realice systems is environmentally friendly, purified from various impurities, including lime particles and various chemicals. Also, with the help of the installation, almost complete water degassing occurs. This solution saves water and electricity (see: http://h2ovortex.ru/products).

Said vortex generator of the REALice system is a turbulator protected by patent EA014490 (B1), comprising an inlet forming at least one spiral-shaped conical channel that forms a vortex of a fluid; and a vortex chamber in fluid communication with the inlet, its longitudinal internal section having a funnel-shaped or oval shape and defining a fluid outlet at its end.

The REALice water treatment system is not the limit in the field of ice treatment.

The objective of the invention was to further improve the characteristics of the resulting ice.

This problem is solved by a water treatment system for ice platforms, which includes a vortex generator as the main element, in which, according to the proposal, a hydrodynamic cavitator is installed as a vortex generator, containing a housing with inlet and outlet nozzles, a toroidal cavitation chamber with holes for supplying air to the chamber, or liquid and a secondary cavitation element made in the form of a ring in the groove of the chamber, and a rigidly mounted spiral blade in the inlet nozzle.

The design of this hydrodynamic cavitator is protected by patent RU179223U1. Purpose - disinfection of household waste water, in particular, the effect is achieved by the action of pressure pulsations from cavitation bubbles, as a result of which the cell membrane of bacteria is destroyed and the death of microorganisms.

FIG. 1 shows a sectional diagram of a hydrodynamic cavitator generator.

The hydrodynamic cavitator contains a housing 1 in which an inlet nozzle 2, a toroidal cavitation chamber 3, an outlet nozzle 4, as well as a groove 5 and a ring 6 are made. In the housing 1 there are holes 7 for sucking in air (gas) or liquid, or both at the same time ... The inlet nozzle 2 and the outlet nozzle 4 are narrowed in the area of connection with the chamber 3. The hydrodynamic cavitator in the inlet nozzle 2 in its converging part contains a rigidly mounted spiral blade 8. In the proposed hydrodynamic cavitator, the inlet nozzle 2 can be displaced relative to the axis of the cavitation chamber 9. The material for the manufacture of all main parts is stainless steel.

FIG. 2 shows a general diagram of the proposed water treatment system for ice rinks.

The water treatment system for ice areas includes a hydrodynamic cavitator unit 10. This unit can include a self-priming pump for stable operation of the cavitator, as a result of which it can be used with water supply networks with any pressure. The system is supplemented with a coarse filter 11 and an iron-removing sediment filter 12.

Water, passed through the proposed system, allows achieving the following results:

- the temperature range of the water used is from +4 to + 80 ° С;

- the prolonged effect of water treatment during cavitation reaches 1 year or more (storage and storage of prepared water is possible), for comparison: the effect of water treatment by the Realise system disappears after 24 hours (water returns to its original state).

It should be noted that according to other criteria of comparison with the prototype, the claimed technical solution is at least not inferior to the Realise system, in particular:

- there is a decrease in the viscosity of water (the quality of filling cracks and other defective zones improves);

- the thermal conductivity of water improves more than 3 times (the freezing time is accordingly reduced: the freezing rate of ice, in comparison with pouring hot water, increases 2 times);

- while maintaining the capacity of the refrigeration unit, the ice temperature decreases by 1.5-2 degrees;

- the quality of the ice improves - it becomes "faster" (the subjective opinion of the hockey and figure skating coaches, expressed during the tests).
