COMBINED COOLING TOWER WITH RATIONAL WATER RECYCLING SYSTEM Russian patent published in 2017 - IPC F28C1/06 F28F25/06 

FIELD: power industry.

SUBSTANCE: combined cooling tower with a rational water recycling system contains a body, in the lower part of which there is a water basin made in the form of a body from water-shield panels, and above the bathroom there is an air intake device made in the form of the louvered grilles located along the body perimeter. In the upper part of the cooling tower body, the axial fan body is installed, made of fiberglass and incorporating a confuser located coaxially with the cooling tower body and rigidly connected to it. The cylindrical part is coaxially connected with the confuser, inside of which a fan impeller with a gap and a diffuser are located, in which, at least, three adjustable extensions are fixed to install the fan with an integrated electric motor. In the middle part of the cooling tower body, there is a water distribution system with manifolds of variable cross-section and fixed with nozzles sprinkling water over the irrigation device fixed in the body by means of stiffeners, the recycling water system has separate hydraulic circuits for water preparation and consumption. In the lower part of the cooling tower body, at least, two water collection tanks are installed, which are connected to each other by a compensation pipe, ensuring the hydraulic independence of the contours of working water preparation and its consumption. One tank is connected with the pump supplying water cooled in the cooling tower to the user, water is again supplied via the valve and the pipeline to the second tank, from it the heated water is supplied by the pump via the filter and the valve along the pipeline to the header with the nozzles installed in the upper part of the cooling tower body, in the section between the filter and the valve the system monitoring the filter water resistance is installed, it contains a pressure gauge and a valve. Each nozzle of the water distribution system containes a hollow body with a nozzle and a central core, the body is made with a channel for supplying water and contains a coaxial sleeve rigidly connected with it with a nozzle fixed in its lower part, the nozzle is made in the form of a cylindrical two-step sleeve, the upper cylindrical step of which is connected by means of the thread joint with the central core coaxial with it, having a central hole and installed with the annular gap relatively to the internal surface of the cylindrical sleeve. The said annular gap is connected with, at least, three radial channels made in the said two-step sleeve connecting it with the annular cavity formed by the sleeve inner surface and the outer surface of the upper cylindrical step. The annular cavity is connected with the body channel for supplying water, an atomizer is fixed to the central core in its lower part, formed as a truncated cone coaxial to the central hole of the core and fixed with its upper base to the base of the central core of the cylinder, and a divider is fixed to the lower base of the truncated cone by means of, at least, three spokes, which are made in the form of an annular end plate, the edges of which are bent towards the annular gap, and on the outer side of the truncated cone there are helical grooves, and in the divider, which is fixed to the lower base of the truncated cone by means of, at least, three spokes and is made in the form of an annular end plate, the edges of which are bent towards the annular gap, there is an orifice axisymmetric to the central hole of the central core.

EFFECT: improving the efficiency of the secondary energy resources by increasing the active area of the cooling tower without increasing aerodynamic resistance.
