Cleaning of shell-and-tube heat exchangers
Thread Content
We have two distillation condensers (used for heat exchange between circulating water and the material), horizontal type, which have been in use for almost 3 years now. Their heat exchange efficiency is getting worse and worse; we plan to shut them down for cleaning. Are there any solutions available for this type of shell-and-tube heat exchanger? Could you please send one for reference? Thank you!
Is the scaling inside or outside the tube? For the inside of the pipe, hydraulic cleaning can be considered; for the outside, chemical cleaning can be used, with cleaning agents circulated
We have previously used alkaline cleaning and steam treatment to clean the interior; the main focus was on the tube side, and it was also possible to block some of the tubes in order to increase the flow rate
It depends on whether the scaling occurs in the tube side or the shell side If the pipe lining is severely damaged, high-pressure water cleaning can be used directly; our company often employs high-pressure water cleaning for this purpose. However, strict attention must be paid to the safety aspects of high-pressure water cleaning, as it poses a high level of risk!
