VENTILATOR COOLING TOWER Russian patent published in 2013 - IPC F28C1/02 

FIELD: power engineering.

SUBSTANCE: ventilator cooling tower comprises a body, a spraying device, a water storage tank and a fan, the body comprises two parts - an upper part, comprising a sprinkler and a drop separator, between which there is a header of the spraying device with nozzles and a lower part, in which there is a water storage tank with a fan installed on it, besides, the body is manufactured from thin-sheet stainless steel, and in the water storage tank there is a diffuser, which is a part of the body and is connected with the fan made with a plastic impeller and a multi-speed electric motor, making it possible in process of operation, depending on weather conditions, to vary efficiency of the cooling tower due to variation of air flow, and the drop separator is made with triple corrugation, where the air flow thrice changes movement direction, and as a result, considerable reduction of drop entrainment is achieved, and if air flow in the effective cross section of the drop separator is from 4 to 4.5 m/sec, the extent of separation of the drop moisture makes 99.9%. The drop entrainment value makes 0.1% of water amount flowing via the cooling tower in the rated mode, and reduction of water flow via the cooling tower reduces the drop entrainment value down to 0.05%. The water amount to be added into the system to compensate for evaporation is determined on the basis of water flow and difference of water temperatures at the inlet and outlet of the cooling tower, the absolute water pressure is determined using a pressure gauge installed upstream the input header according to the following formula: H=10P_A, where H - water head upstream the nozzle (m. water column), P_A - pressure gauge readings (kgf/cm), at the same time water flow via the cooling tower is determined according to the following formula: w=G¹ _w×n, where G¹ _w - water flow via the nozzle (m/hr), n - number of nozzles (pcs.).

EFFECT: cooling tower performance improvement.
