Description

Technical Field

[0001] The utility model relates to a high-tower soft water cooling tower. Background Art

[0002] In the process of compound fertilizer production, a large amount of soft water is required for cooling during high tower granulation. The soft water that completes heat exchange in the high tower will enter the cooling tower through the pipeline for cooling and then reused. For the structural features of the existing conventional cooling tower, please refer to Chinese patent CN219301353U. In actual use, there are the following problems:

[0003] 1. For the plate heat exchanger in the high tower granulator, the required cooling soft water temperature must be lower than 32°C, and most cooling towers are built outdoors. In the hot summer weather and under direct sunlight, the wet bulb temperature of conventional cooling towers has exceeded 32°C, and the outlet water temperature can no longer meet the cooling needs of the high tower granulator;

[0004] 2. The water reservoir or water tank on the lower side of the cooling tower body is generally made of brick structure to prevent water pressure from damaging it. However, the strength of the brick structure will decrease significantly after thermal expansion and contraction, and it is prone to cracking and leakage.

[0005] 3. In winter, when the temperature is low and the cooling tower is not working at night, the water in the reservoir or water tank freezes and expands, causing damage to the reservoir. Moreover, once the pipeline is frozen, the water cannot circulate when it is used again, affecting the normal operation of the high tower granulation. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a high-tower soft water cooling tower, which can ensure the normal operation of the cooling tower under high temperature and extremely cold weather, and can avoid the leakage problem of the water reservoir or water tank.

[0007] In order to solve the above technical problems, the utility model provides a high-tower soft water cooling tower, including a tower body and a water reservoir, wherein the upper side of the tower body water reservoir is open, the tower body is arranged above the water reservoir, a heat exchange and ventilation component is arranged in the tower body, an inlet pipe joint and an outlet pipe joint are arranged between the tower body and the water reservoir, the water reservoir comprises an integrated stainless steel liner with an upper side open, the outer surface of the circumferential side wall of the stainless steel liner is provided with a concrete coating layer, a first temperature sensor and a second temperature sensor are respectively arranged at the inner wall position of the stainless steel liner corresponding to the inlet pipe joint and the outlet pipe joint, and a third temperature sensor is arranged at the inner wall position of the stainless steel liner near the bottom of the pool A first refrigerant coil is provided in the water reservoir, and the first refrigerant coil is connected to the bottom of the stainless steel liner through a bottom mounting seat. An external cabinet is provided beside the water reservoir, and the external cabinet includes a casing, a second refrigerant coil is provided in the casing, and a compressor and an electronic expansion valve are respectively provided at both ends of the second refrigerant coil. The second refrigerant coil is connected to the first refrigerant coil through two external pipelines to form a refrigerant loop. A fan is provided at a position in the casing opposite to the second refrigerant coil. A power controller is also provided in the casing, and the compressor, the electronic expansion valve, the fan, the first temperature sensor, the second temperature sensor, and the third temperature sensor are all electrically connected to the power controller.

[0008] For the purpose of simple explanation, the high tower soft water cooling tower described in the present utility model is referred to as the cooling tower below.

[0009] How to use this cooling tower: When the cooling tower is working normally, the first temperature sensor and the second temperature sensor monitor the inlet water temperature and the outlet water temperature at all times, thereby judging the operation status of the cooling tower. When it is found that the outlet water temperature cannot be maintained after the inlet water temperature rises, it means that the heat exchange limit of the cooling tower has been reached. At this time, the compressor and the fan are started, and the refrigerant absorbs heat in the first refrigerant coil and releases heat in the second refrigerant coil through phase change, so as to cool the water in the water reservoir until the outlet water temperature is constant and lower than the target temperature; when the cooling tower stops working at night in winter, the third temperature sensor actually monitors the water temperature. When the freezing point is reached, the compressor and the fan are started, and the refrigerant releases heat in the first refrigerant coil and absorbs heat in the second refrigerant coil through phase change, so as to heat the water in the water reservoir to prevent freezing.

[0010] Advantages of this cooling tower: This cooling tower uses the principle of refrigerant phase change to cool or heat the water in the water tank, ensuring the normal operation of the cooling tower in high temperature and extremely cold weather. The one-piece stainless steel lining can ensure the sealing of the water tank and will not crack or leak, while the concrete coating can ensure the structural strength of the side and prevent the stainless steel lining from being deformed due to excessive water pressure in the water tank.
