KOCHETOV SYSTEM OF REVERSE WATER SUPPLY Russian patent published in 2011 - IPC F28C1/00 

FIELD: machine building.

SUBSTANCE: system of reverse water supply with implementation of cooling towers consists of cooling towers interconnected with hydraulic circuits of water preparation and water consumption; each interconnected cooling tower has a case in lower section of which there is installed tank for water collection with system of make-up of water spent for evaporation. The tank is connected to a pump supplying water cooled in the cooling tower to a consumer through a filter. At the section between the filter and a consumer there is installed a system of control of filter hydraulic resistance consisting of a pressure gauge and a valve. Each sprayer has a hollow case axisymmetrical axis of which is perpendicular to axis of an orifice of the collector pipe. By shape the case is made in form of a rotation body generated with curve of the second order, for example spherical in form of truncated ellipsoid or paraboloid of rotation. A strengthening element made in form of a ring equipped with a central bush is installed from the side of a flow through orifice of collector pipe in the sprayer. At least three radial blades connected to the case of the sprayer are also rigidly connected to the central bush. The case is made with two opposite perpendicular to sprayer axis ledges by means of which the sprayer is secured on the collector with yokes with locks. At a lower section of the sprayer case there is made a conic throttle orifice connected to a mixing chamber positioned between the throttle orifice and the strengthening element. Screw-like grooves are made on internal surface of the mixing chamber.

EFFECT: raised efficiency of cooling tower operation.
