COMBINED COOLING TOWER Russian patent published in 2018 - IPC F28C1/00 B05B1/26 

FIELD: power engineering.

SUBSTANCE: invention relates to heat power engineering, in particular to heat exchangers, and can be used in circulating water supply systems of thermal power plants and industrial enterprises, where tower type and / or fan cooling towers are used. Combined cooling tower comprises a body in the form of an exhaust tower with air inlet windows in the lower part, a water trapping device, a water trapping basin placed under the cooling tower body, water distribution system with spray nozzles, which outlets of are directed upwards, irrigation device, sprinkling nozzles, recirculating water supply system has separate hydraulic circuits for water preparation and consumption, at that, in the bottom of the cooling towers bodies, at least two water collecting tanks are located, which are connected to each other by a compensation pipe, ensuring the hydraulic independence of the process water preparations and its consumption loops, at that, one tank is connected to a pump, which supplies water cooled in the cooling tower to a consumer, which again enters via a valve along a pipeline into the second tank, from which heated water is sent via a pump with a filter and a valve along a pipeline to a header with nozzles, placed in the cooling tower body upper part, and in the section between the filter and the valve, a hydraulic filter resistance monitoring system is installed, consisting of a manometer and a valve, at that, each of the water distribution system spray nozzles comprises a hollow cylindrical housing with a throttle washer connected to an union nut to which a liquid flow divider is attached, wherein the liquid flow divider consists of coaxially arranged, perforated conical shells, the space between which is filled with a fine mesh, wherein the apices of the conical surfaces of the shells are directed away from the throttle washer, and in the lower part of the divider is fixed a cylindrical perforated segment fixed on the perforated conical shells, where in the cylindrical perforated segment, fixed in the lower part of the divider on perforated conical shells, there is a flow swirler, made in the form of a spring.

EFFECT: improving the use efficiency of secondary power resources by increasing the value of cooling tower active area without increasing the aerodynamic drag.
