Equipment, like people, needs regular cleaning, and plate heat exchangers are no exception. However, due to the unique structure of spiral plate heat exchangers, there are many aspects that require special attention during cleaning operations. Below, we analyze this issue, which should be helpful for your work in the future.

First and foremost, the selection of the cleaning agent is crucial, as the right cleaning agent plays a pivotal role in removing dirt from heat exchangers. Currently, the most commonly used method is acid cleaning, which includes organic and inorganic acids. Naturally, factors such as the temperature during cleaning, the concentration of the cleaning solution, the cleaning method, and the duration should not be overlooked; all must be controlled optimally.

The process of cleaning heat exchangers is relatively straightforward, mainly consisting of stages such as flushing, acid cleaning, alkali cleaning, and water washing, until the sediment in the heat exchanger is completely rinsed out. Additionally, pressure testing of the heat exchanger is required, and only after passing the inspection can it be used again.

Only by strictly adhering to the cleaning method for plate heat exchangers can we ensure the effectiveness of the cleaning process. Naturally, this is crucial for the normal operation of work production, and no aspect can be overlooked.
