I have a question regarding the design of cooling towers! Urgent
Thread Content
The company is planning to install a cooling tower, and there are some disputes regarding the flow path of the cooling water. I’ll explain it briefly; I hope experts can help provide some insights. It is a vertical shell-and-tube cooling tower, with air flowing inside the tubes and water flowing between them; there are baffle plates in place. The issue now is whether the cooling water should enter from the bottom or from the top! Entering from the top does allow contact with the gas in counterflow, but due to gravity, the cooling time is reduced. If entry is from the bottom, although the contact time is longer, reverse flow contact is not possible; it’s unclear which gives a better contact effect! Who can help me explain it in detail!
Counterflow contact is not the best method for heat transfer; cross-flow is the best option. It is recommended to introduce the fluid from below; in the presence of baffles, this essentially constitutes cross-flow contact. Moreover, introducing the fluid from below results in a longer contact time, as mentioned earlier
It depends on what you use to cool the gas, as well as the cooling requirements
It can go in and out, just make sure to fill it with water before driving
If the gas that needs to be cooled is under its own pressure (low pressure) or is under negative vacuum, it can be fed in from the top of the condenser! If there is no pressure and a return flow is needed, it must enter from below
It belongs to a counterflow condenser; it is recommended to feed from the bottom and discharge from the top
