Spiral plate heat exchanger is an efficient heat exchanger equipment, suitable for steam steam, steam liquid, liquid-liquid, and liquid to liquid heat transfer. It is suitable for industries such as chemistry, petroleum, solvents, pharmaceuticals, food, light industry, textiles, metallurgy, steel rolling, coking, etc. This article mainly introduces the characteristics of spiral plate heat exchangers.

To achieve the purpose of mechanical cleaning, one end of the detachable spiral channel is opened, and the spiral plate heat exchanger is sealed with a flat cover and gasket to prevent fluid leakage into the atmosphere or fluid short circuit in the same channel. The structure of the non detachable spiral plate heat exchanger is relatively simple, and all the oil coolers at both ends of the spiral channel are welded together. The detachable spiral plate heat exchanger shell and tube heat exchanger is completely the same as the non detachable one except for the sealing structure at both ends of the spiral channel.

The working temperature of spiral plate heat exchangers depends on the selected materials, which are mostly carbon steel, stainless steel, aluminum, copper, and titanium. In order to improve the pressure bearing capacity of the spiral plate, fixed distance columns are used to support between the plates. There are two types of fluid inlets and outlets on the cylinder: normal and tangential connections. China commonly uses tangential nozzles, which have low fluid resistance and are prone to impurities being flushed out of stainless steel reaction pots. The use of rotary supports is relatively convenient, allowing the heat exchanger to be placed vertically or horizontally. The A and B fluids for heat exchange flow through both sides of the spiral plate, with one fluid flowing out along the spiral channel from the outside to the inside and reaching the central outlet. Spiral plate heat exchanger, while the other fluid is fixed tube plate heat exchanger, which enters from the center along the spiral channel and flows out from the inside out. Two fluids flow in a pure countercurrent manner.
