SYSTEM OF RECYCLING WATER SUPPLY Russian patent published in 2018 - IPC F28C1/00 

FIELD: power industry.

SUBSTANCE: system of recycling water supply contains heat exchangers connected by direct and reverse water mains to the pool-mixer equipped with a cooler connected to the straight main by a connecting pipeline with a flow regulator and an ejector, the mixing chamber of which is connected to the return water main with a pressure regulator, and the nozzle part of ejector on the inside of surface has helical grooves associated with an annular groove connected to the contaminant collector, wherein the cooler includes a vertical body, whose side walls and sectional partitions installed therein are zigzag-shaped and form diffusers and confusers in each section located in staggered order relatively to adjacent section, in addition, the flow regulator is provided with a gate with a speed regulator drive in the form of a block of powder electromagnetic clutches, and on straight water main a temperature sensor is installed, connected to a temperature controller that contains a comparison unit and a reference unit, wherein the comparison unit is connected to the input of electronic amplifier equipped with a nonlinear feedback unit, in addition, the output of electronic amplifier is connected to the input of a magnetic amplifier with a rectifier whose output is connected to the gate speed drive controller, wherein the partitions of diffusers and confusers are made of bimetal, wherein the internal diffuser material has thermal conductivity coefficient of 2.0-2.5 times higher than the thermal conductivity coefficient of confusers internal material, while the heat exchangers are equipped with a thermoelectric generator, made in the form of a body with two communicating channels for hot and cool water with a set of differential thermocouples, "hot" ends of which are located inside the pass-through channel, for hot water, and their "cold" ends are located in the pass-through channel for the cool water, wherein the input of pass-through channel for hot water is connected through three-way valve with return main after the heat exchangers, and its output is connected to the return main before the pool-mixer, in addition, the input of pass-through channel for cool water is connected with a straight pressure main before the pressure regulator, and its output is connected through three-way valve with the pool-mixer, wherein the outer surface of each of heat exchangers is covered with fine basaltic material, made in the form of twisted beams, longitudinally elongated from the straight main in front of heat exchangers to a return main after the heat exchangers. The "hot" and "cold" ends of the set of differential thermocouples in the pass-through channels for hot and cool water of thermoelectric generator body are covered with a dielectric made of tantalum oxide.

EFFECT: invention provides normalized thermo emf values.
