SYSTEM OF WATER REUSE (VERSIONS) Russian patent published in 2010 - IPC F28C1/00 

FIELD: machine building.

SUBSTANCE: system of water reuse implementing cooling stacks consists of cooling stacks interconnected with hydraulic circuits for water preparation and consumption. The cooling stacks have separate hydraulic circuits for water preparation and consumption. Each interconnected cooling stack consists of a case in a lower part of which there are installed at least two tanks for water collection. The tanks are interconnected with a compensating tube providing hydraulic independence of circuits for preparation and consumption of working water. Also, one tank is connected to a pump supplying water cooled in the cooling stack to a consumer. This water is returned through a valve along a pipeline into the second tank. From the second tank via a filter and the valve and along the pipeline water is supplied into the collector with sprayers arranged in an upper part of the cooling stack case. The system of control of hydraulic resistance of the filter is installed at the section between the filter and the valve. The system consists of a gauge and a valve. The system of control of hydraulic resistance of the system is installed at the section between the pump and a consumer.

EFFECT: raised efficiency of cooling stack operation.
