Description

Technical Field

[0001] The utility model belongs to the technical field of cooling towers, and particularly relates to a device for regulating and controlling the outlet water temperature of a cooling tower. Background Art

[0002] A cooling tower is a device used to reduce the temperature of cooling water in industrial equipment or power plants. It cools the water by spraying hot water inside the tower and using natural or forced air to cool the water. A cooling tower usually consists of a tall tower and a bottom pool. In the prior art, the contact area between the cooling water and the air is insufficient, resulting in a reduction in the heat exchange efficiency between the high-temperature water and the air inside the cooling tower, so that the outlet water temperature of the cooling tower is relatively high, which may not meet the temperature requirements of industrial equipment or power plants and affect their normal operation. Content of the Utility Model

[0003] In order to overcome the problem that during the use of a cooling tower, the insufficient contact area between the cooling water and the air leads to a reduction in the heat exchange efficiency between the high-temperature water and the air inside the cooling tower, affecting the normal operation of subsequent equipment.

[0004] The technical solution of the utility model is: a device for regulating and controlling the outlet water temperature of a cooling tower, including a housing assembly; further including a water inlet assembly, a drum assembly, a splash-proof assembly, and a water storage assembly; a water inlet assembly for water inlet is arranged on the housing assembly; a drum assembly for expanding the heat-receiving area of high-temperature water is arranged on the housing assembly; a splash-proof assembly for preventing splashing is arranged on the drum assembly; a water storage assembly for storing cooling water is arranged on the drum assembly.

[0005] Preferably, high-temperature water is injected into the housing assembly through the water inlet assembly, and the water discharged by the water inlet assembly is preliminarily cooled by the housing assembly. Then the drum assembly is started to break up and splash the high-temperature water flowing out of the housing assembly, thereby increasing the heat-receiving area of the high-temperature water. The water flows into the water storage assembly from the splash-proof assembly, solving the problem of reduced heat exchange efficiency between the high-temperature water and the air inside the cooling tower.

[0006] As a preference, the housing assembly includes a housing, a first groove, a second groove, a fixing frame, a first motor, a fan blade, and a cooling filler; a first groove is penetrated and opened on the outer wall of the housing; a second groove is penetrated and opened at the upper end of the housing; a fixing frame is fixedly connected to the inner wall of the second groove; a first motor is fixedly connected to the upper end of the fixing frame; the output shaft of the first motor passes through the lower end of the fixing frame and is fixedly connected to the fan blade; a cooling filler is fixedly connected to the lower part of the inner wall of the housing. By starting the first motor, the output shaft of the first motor drives the fan blade to rotate, sucking air from the lower end of the cooling filler and exchanging heat with the water in the cooling filler, and finally discharging the water vapor and hot air from the upper end of the housing, thereby cooling the high-temperature water.

[0007] Preferably, the water inlet assembly includes a water inlet pipe, a pipe body, a water spray pipe and atomizing sheets; the inner wall of the first tank is fixedly connected with the water inlet pipe; the lower end of the water inlet pipe is fixedly connected with the pipe body in a penetrating manner; the outer wall of the pipe body is fixedly connected with evenly distributed water spray pipes in a penetrating manner; the outer wall of the water spray pipe is fixedly connected with evenly distributed atomizing sheets in a penetrating manner. The water inlet pipe is connected to the high-temperature water discharge outlet. High-temperature water flows into the water spray pipes on the pipe body through the water inlet pipe, and finally is atomized and discharged through the atomizing sheets on the water spray pipes.

[0008] Preferably, the drum assembly includes a first support column, a first through hole, a second motor, a rotating cylinder, a second through hole and a waterproof shell; the lower end of the housing is fixedly connected with evenly distributed first support columns; the outer wall of the first support column is provided with a first through hole; the outer wall of the first support column is fixedly connected with a second motor; the output shaft of the second motor passes through the first through hole and is fixedly connected with the rotating cylinder; the rotating cylinder is rotatably arranged at one end where two first support columns are close to each other; the outer wall of the first support column is fixedly connected with a waterproof shell; the second motor is installed on the inner wall of the waterproof shell. When water flows out from the cooling filler, by starting the second motor, the output shaft of the second motor will drive the rotating cylinder to rotate, and the water contacts the outer wall of the rotating cylinder and splashes, causing the water to splash at the lower end of the housing, expanding the contact surface between the water and the air. Part of the water rotates on the inner wall of the rotating cylinder for heat dissipation and finally is discharged through the second through hole. The waterproof shell is used to protect the second motor inside from water ingress.

[0009] Preferably, the splash-proof assembly includes a fixed block and a third tank; the outer wall of the first support column is fixedly connected with the fixed block; the upper end of the fixed block is provided with a third tank. The water splashing on the outer wall of the rotating cylinder will fall on the inner wall of the third tank. The fixed block can prevent high-temperature water from splashing to the outside of the device, and finally the water flows from the inner wall of the third tank to the inner wall of the liquid storage tank.

[0010] Preferably, the water storage assembly includes a liquid storage tank, second support columns, a drain pipe and a solenoid valve; the lower end of the first support column is fixedly connected with the liquid storage tank; the lower end of the liquid storage tank is fixedly connected with evenly distributed second support columns; the lower end of the liquid storage tank is fixedly connected with the drain pipe in a penetrating manner; a solenoid valve is arranged on the inner wall of the drain pipe. The liquid storage tank is used to store the cooled water from the cooling filler and the third tank. By opening the solenoid valve, the water in the liquid storage tank can be discharged through the drain pipe for recycling.

[0011] Preferably, the outer wall of the liquid storage tank is in the same plane as the outer wall of the fixed block; the lower part of the inner wall of the third tank is inclined. The inclined inner wall of the third tank can prevent water from accumulating on the inner wall of the third tank and facilitate the water to flow into the inner wall of the liquid storage tank.

[0012] Advantages of the present utility model:

[0013] 1. When water flows out of the cooling filler, by turning on the second motor, the output shaft of the second motor drives the rotating cylinder to rotate. The water contacts the outer wall of the rotating cylinder and splashes, causing the water to splash at the lower end of the housing, expanding the contact surface between the water and the air. Part of the water rotates on the inner wall of the rotating cylinder for heat dissipation, solving the problem that the insufficient contact area between the cooling water and the air leads to a reduction in the heat exchange efficiency between the high-temperature water and the air inside the cooling tower;

[0014] 2. By turning on the first motor, the output shaft of the first motor drives the fan blades to rotate, sucking air from the lower end of the cooling filler and exchanging heat with the water inside the cooling filler. Finally, the water vapor and hot air are discharged from the upper end of the housing, thereby cooling the high-temperature water;

[0015] 3. The water splashing on the outer wall of the rotating cylinder will fall on the inner wall of the third tank body. The fixing block can prevent the high-temperature water from splashing outside the device, and the water finally flows from the inner wall of the third tank body to the inner wall of the liquid storage tank.
