[Abstract]]:
Plate heat exchanger is one of the main heat transfer equipment in the field of heating, because of its many advantages are widely used in various fields. However, with the extension of the use of time, there will be plate heat exchanger corrosion problems, that in the end what factors will lead to plate heat exchanger corrosion, plate heat exchanger manufacturers to share with you the causes of plate heat exchanger corrosion and solutions.
Plate heat exchanger is one of the main heat transfer equipment in the field of heating, because of its many advantages are widely used in various fields. However, with the extension of the use of time, there will be plate heat exchanger corrosion problems, that in the end what factors will lead to plate heat exchanger corrosion, plate heat exchanger manufacturers to share with you the causes of plate heat exchanger corrosion and solutions. The following is a summary of the plate heat exchanger manufacturers plate heat exchanger corrosion reasons: 1 plate will have a lot of gaps, such as after the installation is completed or with the bottom of the sealing groove and the groove point will produce cl enrichment, with a long time of enrichment will be greater than the plate corrosion resistance will occur plate heat exchanger corrosion. 2. The stainless steel plate made by mechanical stamping will leave a lot of residual force on the surface. Some stainless steel plates do not contain molybdenum elements, and the residual force attached to the surface is difficult to remove or cannot be removed. 3., as well as chloroprene rubber binder, containing calcium chloride, after water and steam heating, the temperature will gradually rise, from the binder in the hydrogen ion and chloride ion precipitation to produce hydrogen chloride, is also one of the causes of plate heat exchanger corrosion. 4. temperature corrosion is a chemical reaction, with the increase of temperature will gradually rise to 10 degrees Celsius, accelerate the corrosion rate between 1-3 times. 5. Medium concentration: If in hydrochloric acid, the greater the concentration, the more serious the corrosion, the corrosion will be very serious in sulfuric acid with 50% concentration of stainless steel and carbon steel. When the concentration increases to 60%, the corrosion will decrease greatly. The sealing gasket in the corrugated plate is an important pleaser for deformation in the whole plate. After the plate heat exchanger is clamped, the gasket will have a great preload effect due to deformation and sealing groove. During operation, the gasket and sealing groove will slide. Will accumulate in the gap area, resulting in the concentration of the gap will be as high as several times or dozens of times, accelerate the corrosion rate of the plate heat exchanger. After the corrosion causes of the plate heat exchanger are found, how to solve this problem? 1. can choose the anti-corrosion plate heat exchanger material, the corrosion-resistant heat exchange equipment. 2. After installing and running the heat exchanger, try to avoid the above corrosion and prolong the corrosion. 3. For the choice of adhesive, you can choose non-chlorine elements, but also can effectively avoid the increase of corrosion.
