For different types of closed cooling tower, the corresponding energy saving measures are also different, such as cross-flow cooling tower should be set to prevent the short circuit circulation of air from the bottom of the packing to the water surface measures; The height from the top of the packing to the lower edge of the fan suction section should be equal to or greater than 0.2 times of the fan diameter.
Closed cooling tower fan is the core equipment of circulating water system. From the perspective of circulating water equipment management, the fan occupies a large proportion in terms of the number of equipment, maintenance workload, power consumption and so on. Then how to make the enclosed cooling tower fan save energy and reduce consumption, and ensure the long cycle operation of the equipment?
For different types of closed cooling tower, the corresponding energy saving measures are also different, such as cross-flow cooling tower should be set to prevent the short circuit circulation of air from the bottom of the packing to the water surface measures; The height from the top of the packing to the lower edge of the fan suction section should be equal to or greater than 0.2 times of the fan diameter.
The water pouring filler of the horizontal closed cooling tower should have a contraction Angle from the top to the bottom of the vertical central axis of the tower. The shrinkage Angle of drop type water pouring filler should be 9° ~ 11°; The shrinkage Angle of film type water pouring filler should be 5° ~ 6°.
The middle windshield baffle should be set for the countercurrent cooling tower with bilateral air inlet. The upper edge of the baffle is 200 ~ 300mm away from the bottom of the packing support beam, and the lower edge reaches below the water surface of the collecting pool of the tower. The height of the airflow contraction section between the top surface of the packing and the inlet of the air duct should comply with the regulations.
When the top cover plate of the closed cooling tower is flat, the top Angle of the airflow contraction section from the top surface of the packing should be less than 90°; When the guide ring (umbrella) is provided under the flat top cover plate, the top Angle of the airflow contraction section from the top surface of the water collector can be 90° ~ 110°. When the top cover plate of the tower is contracted above the water collector, the top Angle of the cover plate in the contraction section should be 90° ~ 110°.
Enclosed cooling tower energy saving and environmental protection
(1) Drift water control
The floating water of cooling tower is an important technical index of environmental protection. For this reason, Trlon water-cooled closed cooling tower adopts a film packing integrated water collector. The special structure of this part enables the hot air flow to change direction several times in the water intake section, and finally captures most of the water droplets carried by the air flow without affecting the surrounding environment. It also avoids a large amount of water mist around the cooling tower in autumn and winter, which seriously affects the beauty of the overall environment. Especially at the moment when environmental protection actions are vigorously promoted, enclosed cooling tower is your best choice.
(2) Noise and vibration control
Special fan for closed cooling tower, low speed operation design, to ensure the cooling tower in the state of low noise operation;
The structure design of membrane type packing can effectively increase the water film area and reduce the noise of dripping water. The bottom of the packing is immersed under the cold water level of the water tray, and the cooling water can flow into the cold water tray coherently as a film to avoid the sound of water flowing to a greater extent.
However, closed cooling tower is a large industrial equipment, and it is inevitable that the operation will produce noise. We can only reduce the noise at the source of the design and halfway through the installation. For example, silencing cotton is added at the noise source and air ducts are installed at the air duct.
