How to form the fouling of stainless steel plate heat exchanger

  Fouling is a relatively common problem in the operation of stainless steel plate heat exchangers. Fouling means that during the long-term flow of How to form the fouling of stainless steel plate heat exchangerthe stainless steel plate heat exchanger, the impurities and calcium and magnesium ions contained in the working medium solidify and deposit on the surface of the stainless steel plate heat exchanger, thereby forming a layer of dirt on the surface of the stainless steel plate heat exchanger.It will hinder the transfer of energy through the heat transfer wall. Dirt not only reduces the heat exchange efficiency and hinders the flow of the medium, but also increases the pressure drop of the stainless steel plate heat exchanger.In the design stage of the heat exchanger, it is necessary to consider the factors that form scale on the heat exchange surface, so that it is possible to reduce the impact of scale and extend the service life of the stainless steel plate heat exchanger.

   When the stainless steel plate heat exchanger may generate dirt for a period of time, the designer uses the dirt coefficient to express the impact of the dirt on the overall use effect of the stainless steel plate heat exchanger, which can improve the life, operating time and efficiency of the stainless steel plate heat exchanger.But this usually increases the area of the stainless steel plate heat exchanger. In many applications, some working media are not particularly clean because they contain some debris, and they must be continuously operated for a long time. The stainless steel plate heat exchanger will be used continuously for a long period without cleaning. We can only compensate for the effect of fouling by increasing the design fouling coefficient of the stainless steel plate heat exchanger, so that the stainless steel plate heat exchanger can still work effectively to the expected time in the scaled state.
