Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a variable-flow water distribution mechanism for a cooling tower. Background Technique

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to reduce the water temperature. It uses the principles of evaporation heat dissipation, convective heat transfer, and radiative heat transfer by means of heat exchange generated when water comes into contact with air flow and steam volatilizes to carry away heat to dissipate the waste heat generated in industry or refrigeration and air conditioning to reduce the water temperature, so as to ensure the normal operation of the system. The device is generally barrel-shaped, so it is called a cooling tower.

[0003] In a cooling tower, a fan at the top is used to extract the hot air inside, so that the surrounding cold air enters the cooling tower from the side for the heat exchange process. However, when the air wind force in the external environment is large, the side air intake of the cooling tower will change due to the external wind force, resulting in different temperatures inside the cooling tower due to different air intakes, and the heat exchange efficiency at some positions inside the cooling tower will decrease. Content of the Utility Model

[0004] The purpose of the utility model is to provide a variable-flow water distribution mechanism for a cooling tower to solve the problem that the external wind force affects the side air intake of the cooling tower and results in poor internal heat exchange effect proposed in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A variable-flow water distribution mechanism for a cooling tower, including a cooling tower body,

[0006] A vertical metal pipe is installed inside the cooling tower body, and the top of the metal pipe is connected to a cross-shaped connecting steel pipe. The end of the connecting steel pipe is connected to a spray rack. The outside of the spray rack is inserted into the inner wall of the cooling tower body, and a plurality of spray heads are installed at the bottom of the spray rack.

[0007] Fillers are installed inside the cooling tower body, and a temperature sensor is installed on the inner wall of the cooling tower body. A receiving net is also provided below the fillers inside the cooling tower body.

[0008] By adopting the above technical solution, when in use, when the temperature inside the cooling tower body is uneven, if uniform spraying is still carried out, it will lead to a decrease in the heat exchange efficiency at some positions. The temperature inside the cooling tower body is detected by the temperature sensor, and the water flow rate at the connecting steel pipe is controlled by the solenoid valve. The spraying amount on the side with a higher temperature is reduced, and the spraying amount on the side with a lower temperature is increased, so as to improve the heat exchange effect.

[0009] As a further solution of the present utility model: an air inlet is provided on the side wall of the cooling tower body between the filler and the receiving net, an air outlet is provided at the top of the cooling tower body, and an exhaust fan is installed in the air outlet.

[0010] By adopting the above technical solution, during use, the outside air can conveniently enter the cooling tower body through the air inlet, and the exhaust fan in the air outlet facilitates the discharge of the air at the top inside the cooling tower body.

[0011] As a further solution of the present utility model: a drainage box is installed at the bottom of the cooling tower body, a drain pipe is connected to the side wall of the drainage box, and a drainage pump is installed on the drain pipe.

[0012] By adopting the above technical solution, during use, the drainage box receives the water dripping from the bottom inside the cooling tower body and discharges and collects it through the drain pipe.

[0013] As a further solution of the present utility model: a water baffle is installed inside the cooling tower body between the spray rack and the air outlet.

[0014] By adopting the above technical solution, during use, the water baffle intercepts the misty water to reduce the loss of liquid.

[0015] As a further solution of the present utility model: a control panel is installed on the side wall of the cooling tower body, and the control panel is electrically connected to the solenoid valve and the temperature sensor.

[0016] By adopting the above technical solution, during use, the control panel receives the signal from the temperature sensor, and the control panel controls the opening and closing size of the solenoid valve in real time according to the temperature to control the water flow rate in the connecting steel pipe.

[0017] Compared with the prior art, the beneficial effect of the present utility model is: the variable flow rate water distribution mechanism for this cooling tower

[0018] is provided with a solenoid valve and a temperature sensor. A plurality of temperature sensors are used to detect the temperatures at different positions inside the cooling tower body, and then the water flow rate entering the corresponding spray rack is changed through the solenoid valve.
