Description

Dividing wall type closed cooling tower Technical Field The utility model relates to a closed cooling tower, in particular to a dividing wall type closed cooling tower. Background A closed counter-flow cooling tower is a cooling device that mainly performs a cooling function by circulation of a cooling medium (typically water). The cooling medium circularly flows in the system, absorbs heat generated in equipment or a process, and then enters a cooling tower for cooling. Inside the cooling tower, the cooling medium is in countercurrent contact with the outside air. Specifically, the cooling medium flows downward from the top of the cooling tower, while the outside air enters from the bottom of the tower and flows upward. The countercurrent contact mode ensures that the cooling medium and the air have more sufficient heat exchange time, and improves the cooling efficiency. Because the countercurrent mode enables the cold air to contact the cooling medium with lower temperature firstly, the temperature gradually rises along with the upward flow of the air, and the temperature of the cooling medium gradually decreases, the temperature difference between the cold air and the cooling medium is always kept at a larger level, and therefore heat in the cooling medium can be transferred to the air more effectively, and a better cooling effect is achieved. Then, the existing countercurrent closed cooling tower can only directly use air in the external environment to cool the cooling medium, and when the air temperature in the external environment is higher or the humidity of the air in the external environment is higher in summer, the cooling effect of the cooling medium can be influenced. Disclosure of utility model The utility model provides a dividing wall type closed cooling tower for solving the problems in the related art, and the device solves the problem that the existing countercurrent closed cooling tower is poor in cooling effect caused by directly using air in the external environment. In order to solve the problems, the following technical scheme is provided: The dividing wall type closed cooling tower comprises a body with a tube type heat exchanger, wherein the tube type heat exchanger is used for cooling media, and is characterized in that an air inlet surface of the body is provided with a dividing wall cooling mechanism for pre-cooling air entering the body; The partition wall cooling mechanism comprises a gas pre-cooling chamber positioned on the outer wall surface of the body corresponding to the air inlet of the body, an opening is formed in the side wall surface of the gas pre-cooling chamber close to the air inlet, a first air inlet tunnel is formed in the side wall surface of the gas pre-cooling chamber far away from the air inlet, and the first air inlet tunnel and the opening are both corresponding to the air inlet; a partition wall type heat exchange mechanism is arranged in the gas precooling chamber between the first wind inlet tunnel and the opening, two parallel side ends in the partition wall type heat exchange mechanism are respectively an air inlet end and an air outlet end, and the air inlet end and the air outlet end respectively correspond to the positions of the first wind inlet tunnel and the opening; the air pre-cooling chamber is characterized in that a first spraying mechanism for spraying cooling water is arranged in the air pre-cooling chamber above the dividing wall type heat exchange mechanism, the top and the bottom of the dividing wall type heat exchange mechanism are respectively a cooling water inlet end and a cooling water outlet end, a second air inlet tunnel is arranged on the side wall surface of the air pre-cooling chamber below the first air inlet tunnel, and a first fan is arranged at the top of the air pre-cooling chamber. Through the technical scheme, through the arrangement of the gas precooling chamber, when the humidity of the external environment is low or in winter, the air in the external environment can be directly used as a medium for cooling, at the moment, the first fan is closed, the first spraying mechanism is closed, the air in the external environment is not precooled at the moment, the air in the external environment directly enters the air inlet end through the first air inlet hole, passes through the dividing wall type heat exchange mechanism and then enters the body through the air outlet end, and at the moment, the air can directly cool the cooling medium and can also ensure the cooling effect of the cooling medium; When the temperature of the external environment is higher or in summer, if the air directly enters the body to cool the cooling medium, the cooling effect of the cooling medium is affected, and then the first fan and the first spraying mechanism are opened, the air in the external environment enters the air inlet end through the first air inlet hole, the first spraying mechanism sprays cooling water on the dividing wall type he
