Advantages And Disadvantages Of Spiral Plate Heat Exchanger

  The spiral plate heat exchanger is a high-efficiency heat exchanger device, which is suitable for steam-vapor, vapor-liquid, liquid-liquid, and liquid heat Advantages and disadvantages of spiral plate heat exchangerstransfer. It is suitable for chemical, petroleum, solvent, pharmaceutical, food, light industry, textile, metallurgy, steel rolling, coking and other industries.

  Advantages of spiral plate heat exchanger: The spiral plate heat exchanger has a compact structure and a large heat transfer surface per unit volume. For example, the heat transfer surface of a spiral plate heat exchanger with a diameter of ¢1500mm and a height of 1200mm can reach 130.The fluid allows a high flow rate in the spiral plate and flows in the spiral direction, and the stagnant layer is thin, so the heat transfer coefficient is large and the heat transfer efficiency is high. In addition, due to the large flow rate, dirt is not easily retained.

  Disadvantages of spiral plate heat exchangers: spiral plate heat exchangers require high welding quality and difficult maintenance. Heavy weight, poor rigidity, special care should be taken when transporting and installing spiral plate heat exchangers.

Compared with the general tubular heat exchanger, the spiral plate heat exchanger is not easy to block, especially the suspended particles such as sediment and small shell are not easy to deposit in the spiral channel: one is the deposition of single channel impurity in the channel. The flow that forms the turnover will increase until it is washed away.In addition, there is no dead angle in the spiral channel, and impurities are easily rushed out.
