The plate heat exchanger is a high-efficiency heat exchanger assembled from a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates. Plate heat exchangers are widely used in many industries. During the use of the board changer, due to the long medium or longevity, the phenomenon of scaling occurs. We can use a high-pressure water gun to wash the scale on the plates of the plate heat exchanger. But we don't do this for oil pollution. How to clean the oil on the plate heat exchanger?
The fouling on the plates of the plate heat exchanger will cause a very large loss to the total industrial output value. Oil dirt is the most common and difficult to clean.The most easily scaled atmospheric and vacuum distillation unit and the plate heat exchanger in the catalytic cracking unit. This type of fouling is mainly hydrophobic organic mixture film-like grease. Generally, it can be used when cleaning the plate heat exchanger. Some substances with oil stain dissolution reaction are used to remove oil stains, such as petroleum solvents and halogenated solvents.
