Stainless Steel Plate Heat Exchanger And Fouling

  The plate heat exchanger is a heat exchanger made by pressing thin metal plates into heat exchange plates with a certain corrugated shape, which Stainless steel plate heat exchanger and foulingare stacked and fastened with frame plates and bolts.Thin rectangular channels are formed between various plates to exchange heat through the plates. The working fluid flows through the narrow and tortuous channel formed between the two plates.The fouling of the stainless steel plate heat exchanger means that the working medium passes through the heat exchanger for a long period of time, and the impurities and calcium and magnesium ions contained in the working medium solidify and deposit on the surface of the heat exchanger. A layer of dirt is formed on the surface of the stainless steel plate heat exchanger, which in turn hinders the transmission of energy through the heat exchange wall.Fouling can reduce the heat exchange efficiency, hinder the flow of media, and increase the pressure drop of the heat exchanger.Considering various operational issues, the factors that will form scale on the heat transfer surface must be properly considered in the design stage. It is possible to reduce the impact of fouling to a lower level, thereby extending the service life of stainless steel plate heat exchangers as much as possible.
