Plate heat exchanger is a commonly used corrugated high-efficiency heat exchanger in daily life. Plate heat exchangers have good heat transfer efficiency, small heat loss during the heat transfer process, small footprint, and long service life. Therefore, they are widely used in people's daily lives. However, after long-term storage, the heat exchanger will scale. So how to clean plate heat exchangers?
Plate heat exchangers will form scale over time during use. Water contains numerous calcium, magnesium, and bicarbonate compounds, which will decompose into calcium carbonate when heated. Calcium carbonate is a sediment that will deposit in the heat exchanger, forming a thick layer of scale over time. At the same time, soft and shapeless magnesium hydroxide will also be generated, making it easier for scale to form. The cleaning method of
plate heat exchanger is to use acidic cleaning agents for cleaning. Nowadays, the cleaning agents used are mostly organic acids or inorganic acids. Acid washing can effectively help remove scale. Acidic substances can dissolve well and destroy the structure of scale, thereby causing scale to fall off and disintegrate, achieving a good cleaning effect.
