SYSTEM FOR PURIFYING WATER BY RECRYSTALLIZATION AND HEAT EXCHANGE DEVICES (VARIANTS) FOR THE IMPLEMENTATION THEREOF

摘要

The present invention relates to treatment systems for polluted and sea water by recrystallization and may be used in everyday life, the food industry, in the catering business and healthcare.;The system comprises at least two heat-exchange devices that contain chambers for water freezing and ice melting, cooling and heating components, a water circulation loop, a refrigerant circulation loop connected with cooling and heating components able to alternate water freezing and ice melting in the chambers of heat-exchange devices and to transfer the heat generated in the water freezing chamber into the ice melting chamber, a control and monitoring tool. Heat-exchange devices are arranged as a cascade one under another and comprise outer and inner housings as well as a cylindrical baffle, which are coaxial relatively to each other and form an annular cavity between their walls; an air supply manifold, cooling and heating components, a heating component fastened at the top of the inner housing and at least one drain nozzle. The outer housing is cylindrical or truncated cone-shaped with a cone angle directed upwards. The outer housing has an additional inner wall, the shape and height of which meet the outer housing while cooling and heating components are located between the said walls. The baffle and the housing internal wall may be connected to an electrical current source.;The combination of sufficiently large performance and high quality of water treatment in the system allows it to use for treating initial water with a wide range of with organic and inorganic contaminants.;12 clauses of the patent claim, Fig. 3.
