FAN OR CHIMNEY-TYPE COOLING TOWER WITH STEAM TRAP Russian patent published in 2014 - IPC F28C1/02 F28F25/04 

FIELD: agriculture.

SUBSTANCE: fan or chimney-type cooling tower comprises a catchment basin 1 of cooled water and the vertical housing 3 mounted over it above the water level on supports, which is open from below for atmospheric air intake and from above - for exit of the steam-air mixture, and located in the housing 3 irrigation, water distribution and drop-trap devices 5, 6, 7 respectively. Above cooling tower housing 3 the steam trap is mounted in the form of the dome 8 communicated with the atmosphere of a thermally conductive and corrosion resistant material of conical, cylindrical, pyramidal or hemispherical shape with the condensate-trap trough 9 provided along the perimeter of its lower part, connected by the tubular channels 10 with the inner part of the cooling tower housing 3 below drop-trap device 7. The dome 8 can be made continuous with the windows provided in its lower part for outlet to the atmosphere of steam-air mixture partially dried in the steam trap or in the form of the louver system forming the shape of its profile. The area of the space communicating with the atmosphere of the dome 8 of the steam trap is at least 1.5 times greater than the area of the outlet section of the cooling tower housing 3.

EFFECT: invention provides condensation of vapour fro the steam-air mixture at the outlet of the cooling tower with its return it to the catchment basin of the cooling tower.
