Water distribution in the circulating cooling water tower
Thread Content
Hello, everyone! I have a question for everyone: does the freezing of cooling towers in cold winters in the north relate to the packing inside the towers, that is, to uneven water distribution? If it matters, what measures can be taken to prevent it from freezing? When the feedwater temperature cannot be increased.
The uniformity of water distribution is directly related to the nozzles and the water distribution system; in addition, too low a water volume and a too small spraying radius of the nozzles severely affect the even dispersion of water. The water droplets falling downward do not overlap with each other, which also leads to uneven water distribution. The water-repellent areas, where the water spray density is low, have such low enthalpy that they freeze; in fact, there is no inherent connection between freezing and the filler. Solutions: 1. During winter when the ambient temperature is low, it is possible to reduce the number of cooling towers in operation or shut down some of the fans; for example, two fans can be turned off while one remains operational, or three fans can be turned off while one stays on, as long as the process requirements of the installation are met. This approach helps to prevent freezing while also saving energy consumption. 2. During winter operation of the cooling tower, as long as it does not affect the process requirements of the installation, the cooling water does not need to be sent to the tower; it can even be directly added to the water to prevent freezing. 3. If icing occurs due to problems with the use and maintenance of the cooling tower. Measures such as operating the cooling tower at full capacity can be taken to increase the water spray density and melt the ice accumulated inside the tower. 4. In winter, when multiple cooling towers serve the same installation, it is possible to shut down two towers and keep one operational, or shut down three towers and keep one operational, without compromising the process requirements and ensuring the continuous operation of the production facility; by increasing the total water volume, the sprinkling density can be raised to enable full-load operation. If there is anything incorrect, please let me know.
Thank you to the person in floor 2. We use the method of stopping two fans and keeping one running, or we turn off the fans to prevent icing; this approach also meets the process requirements
