WATER REUSE SYSTEM Russian patent published in 2011 - IPC F28C1/08 

FIELD: power engineering.

SUBSTANCE: water reuse system comprises heat exchangers connected with forward and return water manifolds to a mixer pool, which is equipped with a cooler connected to the forward manifold by a connecting pipeline with a flow controller and an ejector, the mixing chamber of which is connected to the return water manifold with a pressure controller, and the nozzle part of the ejector on the inner surface has helical grooves joined to a circular groove connected to a collector of contaminants, besides, the cooler comprises a vertical body, side walls of which and sectional partitions installed in it are made as zigzag-shaped and form diffusers and confusors in each section, which are arranged relative to the neighbouring sections in staggered order, besides, the cooler is equipped with a sprinkler made of nozzles in the form of pairwise expanding nozzles, at the inner surface of which there are curvilinear grooves, besides, in each pair of expanding nozzles on the first one from the pair the produced curved grooves have a clockwise direction, and at the second expanding nozzle of this pair the formed curved grooves have counterclockwise directions, besides, partitions of diffusers and confusors are made of bimetal, at the same time the internal metal of diffusers has the coefficient of heat conductivity that is 2.5-3 times higher than the coefficient of heat conductivity of the internal material of diffusers.

EFFECT: invention makes it possible to maintain efficient operation of water reuse system in case of durable operation under conditions of contamination accumulation as cooled water moves in the cooler due to vibration shaking of solid particles that stick to inner surfaces of diffusers and confusors.
