The plate and shell heat exchanger is composed of a plate bundle composed of a plate group and a shell. It is a plasma arc welded corrugated plate group placed in the shell instead of the heat exchange tube of the original shell and tube heat exchanger. The plate group is used as the heat exchanger of the heat transfer element.
The two fluid media respectively flow through the plate side and the shell side to achieve the purpose of heat exchange. When the fluid flows through the corrugated plates, it can produce high turbulence in the countercurrent direction, which greatly improves the exchange rate. Thermal efficiency, small terminal temperature difference, good sealing, high temperature and high pressure resistance, compact structure, small size, etc. The product can be widely used in refrigeration and air conditioning, electric power, metallurgy, petrochemical, pharmaceutical, shipbuilding, food and other fields.
The industrial plate and tube heat exchanger can be designed in a detachable form or a fully welded form. The maximum design pressure can reach 10MPa. The design temperature is between -196°C and 700°C. The plate material is stainless steel 304, 316L, etc. The advantages of the plate and tube heater are concentrated in one.
