Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically a large-scale antifreeze counterflow cooling tower. Background Technology

[0002] A cooling tower is a device that uses the contact between water and air for heat exchange. It is widely used in industrial, commercial and civil fields. Its core function is to ensure the stable operation of various systems by cooling circulating water.

[0003] Chinese utility model patent CN222460344U discloses a large-scale antifreeze counter-flow cooling tower, including a bottom water collection tank. A cylindrical cooling shell is provided on the upper surface of the bottom water collection tank. A horn-shaped air duct is provided at the upper end of the cylindrical cooling shell. A support column is located in the middle of the cylindrical cooling shell, and a fan is located at the upper end of the support column. A motor that drives the fan is connected to the upper side of the cylindrical cooling shell via a motor mount. An annular water diffuser is provided at the upper end of the inner part of the cylindrical cooling shell, and an L-shaped water inlet pipe is connected to the inlet of the annular water diffuser. An anti-icing device and a packing device are provided inside the cylindrical cooling shell. The sprayed water directly enters the water collection tank and mixes with the existing cold water in the tank, thereby regulating the temperature in the tank. Combined with the operation of the cooling tower fan, the water temperature in the tank is prevented from becoming too low while meeting the temperature requirements of the production process, thus achieving the purpose of antifreeze.

[0004] Traditional cooling towers are prone to water or other media freezing in low-temperature environments, leading to spray pipe blockage, ice buildup inside the tower, and affecting normal operation. The lack of effective temperature monitoring and automatic heating systems prevents timely responses to low temperatures, resulting in unstable operation in cold weather. Therefore, a large-scale, anti-freeze counter-flow cooling tower is needed to solve these problems. Utility Model Content

[0015] 1. This large-scale antifreeze counter-flow cooling tower achieves precise antifreeze control through the installation of an aerogel insulation layer, a temperature control device, and a temperature sensor. The temperature sensor monitors the internal temperature of the cooling tower in real time. When the temperature falls below the set value, it promptly sends a signal to the controller. The temperature control device draws in external air via an air pump, heats it through a sealed heater, and then introduces it into the cooling tower. Working in conjunction with the aerogel insulation layer, this reduces internal heat loss and maintains the internal temperature within a suitable range, preventing abnormal equipment operation or reduced efficiency due to excessive temperature fluctuations. The aerogel insulation layer has excellent insulation performance, effectively blocking heat loss from the cooling tower and reducing heat dissipation. This allows more energy consumed by the heating device to be used to raise the internal temperature of the cooling tower, improving energy efficiency and reducing operating costs. Through the combined action of the temperature control device and the aerogel insulation layer, a suitable internal temperature is maintained, which is beneficial to the heat dissipation and cooling efficiency of the cooling tower. It prevents the normal heat exchange function of the cooling tower from being affected by excessively high or low temperatures, thereby improving the overall operating efficiency of the cooling system.

Device 13, the temperature control device 4 includes a filter cover 401, a fixing pipe 402, a heat dissipation grid 403, a mounting box 404, a sealing heater 405, a connecting pipe 406, an air inlet pipe 407, an air pump 408, and an air outlet pipe 409. The top of the sealing heater 405 is fixedly connected to the inner top wall of the mounting box 404, the bottom of the air pump 408 is fixedly connected to the inner bottom wall of the mounting box 404, one end of the air inlet pipe 407 is fixedly connected to the air inlet end of the air pump 408, one end of the air outlet pipe 409 is fixedly connected to the air outlet end of the air pump 408, one end of the connecting pipe 406 is fixedly connected to the air outlet end of the sealing heater 405, the rear end of the fixing pipe 402 is fixedly connected to the front of the mounting box 404, and the air inlet end of the fixing pipe 402 is threadedly connected to the filter cover 401.

[0022] Specifically, the end of the air outlet pipe 409 away from the air pump 408 is fixedly connected to the air inlet of the sealing heater 405. An installation groove is provided on the right side of the mounting box 404 near the bottom. The heat dissipation grid 403 is installed and fixedly connected inside the installation groove on the right side of the mounting box 404.

[0023] Specifically, the end of the air inlet pipe 407 away from the air pump 408 is fixedly connected to the air outlet end of the fixed pipe 402, and a sealing device is provided at the connection between the air inlet pipe 407 and the fixed pipe 402.

[0024] Specifically, the spray device 5 includes an inlet pipe and a water pump. One end of the inlet pipe is fixedly connected to the inlet end of the water pump, and one end of the spray pipe 9 is fixedly connected to the outlet end of the water pump. The end of the spray pipe 9 away from the water pump passes through the right side of the cooling tower body 7 near the top and is fixedly connected to the inner left side wall of the cooling tower body 7.

[0025] Specifically, an electric heating device 6 is fixedly installed on the outer surface of the spray pipe 9, and the connection between the spray pipe 9 and the cooling tower body 7 is fixed, while one section is connected by a pipe fixing bracket.

[0026] Specifically, the electric heating device 6 consists of a self-regulating electric heating tape and a heat-resistant insulation layer.

[0027] Specifically, the aerogel insulation layer 10 is located between the inner wall of the cooling tower body 7 and the inner wall 12 of the tower.

[0028] Specifically, the end of the connecting pipe 406 away from the sealing heater 405 passes through the inner left side wall of the mounting box 404, the right side of the cooling tower body 7, the aerogel insulation layer 10, and the inner wall 12 of the tower and is fixedly connected to the inner wall 12 of the tower.

[0029] During operation, when the temperature inside the cooling tower falls below a set value, it is detected by the temperature sensor 13. This triggers the electric heating device 6, the air extraction pump 408, and the sealing heater 405. Air from outside the mounting box 404 is drawn into the air extraction pump 408 through the inlet pipe 407, and then flows into the sealing heater 405 through the outlet pipe 409. The sealing heater 405 heats the incoming air, and the heated air flows into the cooling tower body 7 through the connecting pipe 406. This increases the internal temperature of the cooling tower, preventing water or other media from freezing due to low temperatures and ensuring the normal operation of the cooling tower. Simultaneously, the surrounding... The electric heating device 6 outside the spray pipe 9 heats the outer wall of the spray pipe 9 through its self-regulating electric heating tape. Since the spray pipe 9 is a metal pipe, the heat is introduced into the flowing liquid through the spray pipe 9, thereby preventing the liquid inside the spray pipe 9 from freezing due to low temperature and ensuring the normal operation of the spray system. Since the connecting pipe 406 discharges the heated air into the interior of the cooling tower body 7, the aerogel insulation layer 10 inside the cooling tower body 7 plays a role in heat insulation and heat preservation, reducing heat loss, improving energy utilization efficiency, and preventing the external cold air from having an excessive impact on the interior of the cooling tower, further ensuring the stable operation of the cooling tower in low temperature environment.

[0030] In summary, this large-scale antifreeze counter-flow cooling tower achieves precise antifreeze control through the installation of an aerogel insulation layer 10, a temperature control device 4, and a temperature sensor 13. The temperature sensor 13 monitors the internal temperature of the cooling tower in real time, and promptly sends a signal to the controller 3 when the temperature falls below the set value. The temperature control device 4 draws in external air via an air pump 408, heats it through a sealed heater 405, and then introduces it into the cooling tower. Working in conjunction with the aerogel insulation layer 10, it reduces internal heat loss and maintains the internal temperature of the cooling tower within a suitable range, preventing abnormal equipment operation or reduced efficiency due to excessive temperature fluctuations. The aerogel insulation layer 10 has excellent insulation performance, effectively blocking heat loss from the cooling tower and reducing heat loss. This allows more energy consumed by the heating device to be used to raise the internal temperature of the cooling tower, improving energy utilization efficiency and reducing operating costs. Through the combined action of the temperature control device 4 and the aerogel insulation layer 10, a suitable internal temperature is maintained in the cooling tower, which is beneficial to the heat dissipation and cooling efficiency of the cooling tower. It prevents the normal heat exchange function of the cooling tower from being affected by excessively high or low temperatures, thereby improving the overall operating efficiency of the cooling system.
