Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower equipment, in particular to a counter-flow closed cooling tower. Background Art

[0002] A countercurrent closed cooling tower utilizes the pressure generated by a water pump or other pressure device to transport the higher temperature water, i.e., cooling water, coming out of a condenser, absorber or process equipment to the cooling coil of the cooling tower. The circulating water enters the cooling tower and exchanges heat through movement in the cooling tower and contact with the wind fluid. The return water after entering the cooling tower passes through a pressure swirl nozzle device installed at the top of the tower and the upper part of the air duct to form small water droplets that move vertically downward at high speed, thereby completing the task of increasing the surface area of ​​the water droplets. However, due to the fixed direction of the nozzle, the traditional cooling tower cannot guarantee all-round spraying, and the cooling efficiency is low.

[0003] For example, Chinese patent CN218821764U discloses a closed cooling tower, comprising: an outer shell; a water collecting tank located in the lower part of the outer shell, for containing cooling water; a heat exchange tube group installed in the outer shell, located above the water collecting tank, wherein the heat exchange tube group is composed of twisted tubes, and the horizontal spacing of the twisted tubes is the maximum diameter of the twisted tubes; a sprayer, located above the heat exchange tube group to spray cooling water on the heat exchange tube group, wherein the sprayer is composed of a spray water tank, a spray pipe and a plurality of basket-type nozzles fixed under the spray pipe, the spray water tank is installed on the outside of the outer shell, and the spray pipe and the plurality of nozzles are installed in the outer shell, and the spray pipe is connected to the spray water tank and the plurality of nozzles respectively; and a pumping system, installed on the outside of the outer shell, for pumping the cooling water in the water collecting tank to the spray water tank of the sprayer.

[0004] However, the technology has the following problems: it is impossible to adjust the direction of the nozzle to achieve the best cooling effect. During the cooling process, water vapor overflows from the position of the fan, causing damage to the fan and wasting water resources. It is impossible to prevent external impurities from entering the cooling tower, increasing the cleaning workload.

[0005] Based on this, the utility model designs a counter-flow closed cooling tower to solve the above problems. Utility Model Content

[0049] The nozzles 225 are provided in multiple groups at equal intervals and are all fixedly mounted on the through pipe 224 .

[0050] The annular sleeve 221 , annular groove 222 , notch 223 , through pipe 224 , and nozzle 225 are each provided with two groups and are respectively located at the front and rear sides of the working box 211 . The two groups of connecting rods 215 are connected through the pulley assembly 213 and the double gear assembly 214 .

[0051] When the utility model is in use, the boiling cooling medium is introduced into the coil 16 from the liquid inlet, the circulating water pump 18 is started, and the cooling water in the cooling pool 14 is pumped into the annular sleeve 221, and the reduction motor 212 drives the pulley assembly 213 to rotate, and the pulley assembly 213 drives the double gear assembly 214 to move, and the two gears of the double gear assembly 214 move towards each other, so the two connecting rods 215 rotate towards each other, and the two connecting rods 215 drive the two through pipes 224 to rotate towards each other, so that the appropriate spray angle is adjusted according to the temperature to achieve the best cooling effect, the blower 12 is started, and the cold air from the outside is sucked in from the shutter 13, forming convection with the spray water, and the cooling water contacts the wind fluid to exchange heat, thereby improving the cooling efficiency and ensuring the cooling effect, thereby cooling the cooling medium in the coil 16.
