Description

Dividing wall type evaporative cooling tower Technical Field The utility model relates to an open cooling tower, in particular to a dividing wall type evaporative cooling tower. Background The open cooling tower achieves heat transfer through direct contact of water with air. The hot water is sprayed from the top of the cooling tower and comes into full contact with the air flowing upward from the bottom of the tower. During the contact of water with air, a portion of the water evaporates, and the evaporated water vapor absorbs a large amount of heat, thereby reducing the temperature of the remaining water. The flow of air is achieved by a fan of the cooling tower. The fan is usually installed at the top of the cooling tower, and generates negative pressure by rotation to pump the air at the bottom of the tower upwards, so that the air is fully contacted with water and takes away heat. Existing cooling towers typically utilize ambient air directly for heat exchange with the hot water to be cooled. However, when the outside air temperature is higher, the hot water temperature reduction range after heat exchange is limited, and the temperature requirement required by actual use is difficult to reach, so that the cooling effect is influenced. Disclosure of utility model The utility model provides a dividing wall type evaporative cooling tower for solving the problems in the related art, and the device solves the problem that the cooling effect of the existing cooling tower is limited. In order to solve the problems, the following technical scheme is provided: A dividing wall type evaporative cooling tower comprises a body with evaporative cooling filler, and is characterized in that a gas pre-cooling chamber is arranged on the outer wall surface of the body corresponding to an air inlet of the body, an opening is arranged on the side wall surface of the gas pre-cooling chamber close to the air inlet, the opening corresponds to the air inlet, a first air inlet tunnel is arranged on the side wall surface of the gas pre-cooling chamber far away from the air inlet, and a dividing wall type heat exchange mechanism is arranged in the gas pre-cooling chamber between the first air inlet tunnel and the air inlet; The air inlet end and the air outlet end of the dividing wall type heat exchange mechanism respectively correspond to the first air inlet tunnel and the air inlet, and the top and the bottom of the dividing wall type heat exchange mechanism are respectively provided with a spray water inlet end and a spray water outlet end; The cooling water spraying mechanism and the second wind inlet tunnel are arranged in the gas precooling chamber above the dividing wall type heat exchange mechanism. Through the technical scheme, by arranging the gas precooling chamber, when the air humidity in the external environment is low, the cooling water spraying mechanism is closed, so that the air with low temperature directly enters the body for cooling action; when the temperature in the external environment is too high, a cooling water spraying mechanism of the gas precooling chamber is opened, and the air entering the body is pre-cooled through heat exchange of cooling water and hot air, so that the temperature of the air entering the body is reduced, and the cooling effect of hot water to be cooled is obviously improved; Through the setting of second wind inlet tunnel, when the gas temperature that gets into in the gas precooling room is too high, get into dividing wall formula heat transfer mechanism through first wind inlet tunnel and carry out heat exchange with spray water after, the temperature that drops from dividing wall formula heat transfer mechanism risees, first fan opens the indoor air of suction gas precooling this moment, make the gas that gets into from second wind inlet tunnel and the water direct contact that drops on the dividing wall formula heat transfer mechanism, spray water takes place the phase transition temperature and drops into the water catch bowl, for follow-up cooling cycle use, this process has ensured that the cooling water sprays the mechanism and sprays the water on the dividing wall formula heat transfer mechanism at every turn and be in lower temperature all the time, thereby continuously provide efficient cooling effect for the medium of waiting to cool.
