Can a sludge remover be used to clean shell-and-tube heat exchangers?
Thread Content
In a shell-and-tube heat exchanger, circulating water flows through the tube side; blockages occur after long-term use. In the past, this issue was resolved by stopping the operation and using high-pressure water guns for cleaning. Since it is now not possible to stop the operation, online cleaning has been chosen as a solution. It is planned to inject a sludge-removing agent from inside the heat exchanger’s head via backwashing – I’m not sure if this approach will work or if it could have any negative effects on the heat exchanger Have any of the xdjm users on the forum used this method? If so, how much should be added? If too much is added, will it have the opposite effect?
It seems that our company has been using this method for handling things recently; I’m not entirely familiar with the details
The problem of scaling can be addressed using Israel’s CQM online intelligent cleaning system for heat exchangers; you may want to learn more about it if you’re interested. As you mentioned, using sludge removers can help solve some issues, but it becomes a hassle over time. Information on such intelligent cleaning systems is available on our company’s website: www.odismatic.com.
One unit has been cleaned and is now in use; it seems to work fine for now, but it needs to be monitored for some time. This method can complete the cleaning in two days; it works well when there are no leaks in the tube bundle, and no need to remove the shell layer. It is relatively labor-saving.
