CIRCULATING WATER SUPPLY SYSTEM Russian patent published in 2017 - IPC F28C1/00 

FIELD: heating system.

SUBSTANCE: circulation water supply system provides cooling towers, interconnected by hydraulic circuits of preparing and consuming water, cooling towers have separate hydraulic circuits of preparing and consuming water, each of the towers contains body, in bottom of which at least two tanks to collect water, are placed which are interconnected by expending pipe, providing hydraulic independence of circuits of working water preparation and its consumption. One tank is connected to the pump, which supplies cooled in a cooling tower water to consumer, which again goes through a valve on the pipeline to the second tank, from which heated water through the filter and valve is supplied through pipeline to manifold with injectors located in the upper part of cooling tower body, and to the part between the filter and the valve control system of filter hydraulic resistance is installed, consisting of a pressure gauge and valve, each injector contains a hollow shell with a nozzle and a central core, shell is made with conduit for liquid inlet and includes coaxial, tightly associated with it sleeve, with a nozzle fixed at the bottom, manufactured in the form of a two-stage cylindrical sleeve, upper cylindrical stage of which is connected through the screw connection with coaxial to it central core having central hole, and installed with the annular gap relative to the internal surface of cylindrical sleeve. Said annular gap is communicated with, at least, three radial channels made in said two-stage sleeve to communicate with annular cavity formed by sleeve inner surface and outer surface of upper cylindrical stage. Annular cavity is connected to the body for the liquid supply to the central core, in its lower part sprayer is rigidly attached, made in the form of a truncated cone, coaxial to central core hole, and attached by its upper base to the base of the central core cylinder, and to the lower base of the truncated cone, through at least three spokes, divider is attached, which is made in the form of a round face plate whose edges are deflected towards annular gap, and on the outer side surface of truncated cone there are spiral grooves, and at sparger, which is attached to the lower base of truncated cone by at least three spokes and is made in the shape of a round face plate, edges are deflected towards annular gap, throttle opening is made axially to central hole of central core. External diffuser is coaxially attached to the sleeve, tightly associated with injector body, in its bottom part, and to the lower base of sprayer truncated cone, tightly attached to the central core, in its lower part. On the outer side surface of the truncated cone there are screw grooves, the internal perforated diffuser is coaxially attached in such a way that the output sections of the external and internal diffusers lie in one plane.

EFFECT: improving the performance of cooling tower.
