The similarities and differences between non - removable and detachable spiral plate heat exchangers
Jan 06, 2018

Spiral plate heat exchanger is a spiral plate heat transfer element as a highly efficient heat transfer equipment, is ideal for steam - steam, vapor - liquid, liquid and liquid heat transfer, chemical, petroleum, solvents, pharmaceuticals , Food, light industry, textile, metallurgy, steel rolling, coking and other industries have a wide range of applications.


If from the structural point of view, the spiral plate heat exchanger can be divided into non-removable spiral plate and removable spiral plate heat exchanger two categories, but even so, they still have some things in common. For example, the spiral plate heat exchanger is made up of two rolls and forms two uniform spiral channels. The two heat transfer media can flow in full countercurrent and greatly enhance the heat exchange effect. Even two small temperature difference media Achieve the ideal heat transfer effect.


Moreover, the shell of the spiral plate heat exchanger adopts a tangential structure so that the local resistance is small. Since the curvature of the spiral channel is uniform, the liquid does not flow in the apparatus without large steering and the total resistance is small, so that it can be increased Design flow rate to have a high heat transfer capacity.


The different structural design is, non-removable spiral plate heat exchanger spiral channel end face welded seal, which has a high sealing; and detachable spiral plate heat exchanger, one of the channels detachable cleaning, especially applicable Viscous, precipitation of liquid heat exchange.


In practice, if a single spiral plate heat exchanger can not meet the requirements, can be used in combination, but the combination must be parallel combination, series combination, the same equipment and channel spacing and other requirements to ensure that can achieve the desired Effect.
