PROCEDURE FOR REVERSE WATER SUPPLY BY KOCHETOV WITH IMPLEMENTATION OF COOLING TOWERS Russian patent published in 2011 - IPC F28C1/00 

FIELD: machine building.

SUBSTANCE: procedure for reverse water supply with implementation of cooling towers consists in interconnection of several cooling towers with hydraulic circuits of water preparation and water usage in such way, that hydraulic contours of water preparation and water usage function separately. Also, in a lower section of the cooling towers case there are positioned at least two tanks for collection of water interconnected with a compensation pipe thus facilitating hydraulic independence of contours for water preparation and water usage. One tank is connected to a pump supplying cooled in the cooling tower water to a consumer. This water is repeatedly flows into the second tank through a valve and a pipeline. Heated water from the second tank is supplied into a collector through a filter and a valve with sprayers arranged in an upper section of the cooling towers case by means of the pump along the pipeline. At the section between the filter and valve there is installed a system for control of filter hydraulic resistance consisting of a pressure gauge and a valve. Each sprayer has a hollow axisymmetrical case axis of which is perpendicular to axis of an orifice of the collector pipe. By shape the case is made as rotation body generated with a curve of the second order, for example, spherical, in form of truncated ellipsoid or paraboloid of rotation. From the side of the flow-through orifice of the collector pipe a straightening element is installed in the sprayer; the element is made in form of a ring with the central bush. At least three radial blades are rigidly connected with the bush. The blades are also connected to the sprayer case. The case has two opposite ledges perpendicular to axis of the sprayer. The sprayer is fixed on the collector by means of these ledges with yokes with locks. In a lower section of the sprayer case there is made a conic throttle orifice connected with a mixing chamber located between the throttle orifice and the straightening element. Screw-like grooves are made on internal surface of the mixing chamber.

EFFECT: raised efficiency of cooling tower operation.
