The spiral plate heat exchanger is a new type of heat exchanger with good heat transfer efficiency, high running stability and multiple working together.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 transfer. It is suitable for chemical, petroleum, solvent, pharmaceutical, food, light industry, textile, metallurgy, steel rolling, coking and other industries.
(1) The equipment is made up of two rolls to form two uniform spiral channels. The two heat transfer media can carry out full countercurrent flow, which greatly enhances the heat transfer effect. Even two small temperature difference media can achieve ideal heat transfer effect.
(2) The joint on the casing adopts a tangential structure, and the local resistance is small. Since the curvature of the spiral passage is uniform, the liquid does not have a large steering in the apparatus, and the total resistance is small, so that the design flow rate can be improved to have Higher heat transfer capacity.
(3) The end face of the spiral passage of the A type non-removable spiral plate heat exchanger is welded and sealed, thus having a high sealing property.
(4) The structure principle of the B-type detachable spiral plate heat exchanger is basically the same as that of the non-removable heat exchanger, but one of the channels can be disassembled and cleaned. It is especially suitable for heat exchange with viscous, precipitated liquids.
(5) The structural principle of the C-type detachable spiral plate heat exchanger is basically the same as that of the non-removable heat exchanger, but the two channels can be disassembled and cleaned, and the scope of application is wide.
