Spiral plate heat exchanger is a high-efficiency heat exchange equipment, suitable for steam-Steam, steam-liquid, liquid-Liquid, heat transfer to liquid. It is suitable for chemical, petroleum, solvent, medicine, food, light industry, textile, metallurgy, steel rolling, coking and other industries. According to the structural form, it can be divided into non-detachable type (Itype) spiral plate type and detachable type (IItype,IIIType) spiral plate heat exchanger.
Structure and performance
1. This equipment is rolled from two sheets to form two uniform spiral channels. The two heat transfer media can flow in full counter-current, which greatly enhances the heat exchange effect. Even if there are two small temperature difference media, the heat exchange effect can be achieved.
2. The nozzle on the shell adopts a tangential structure, with small local resistance. Since the curvature of the spiral channel is uniform, the liquid flows in the equipment without major deflection, and the total resistance is small. Therefore, the design flow rate can be increased to achieve higher heat transfer capacity.
3,IThe end face of the spiral channel of the non-detachable spiral plate heat exchanger is sealed by welding, so it has high sealing performance.
4,IIThe structural principle of the detachable spiral plate heat exchanger is basically the same as that of the non-detachable heat exchanger, but one of the channels can be disassembled for cleaning, which is especially suitable for sticky products.,Heat exchange with precipitated liquid.
5,IIIThe structural principle of the detachable spiral plate heat exchanger is basically the same as that of the non-detachable heat exchanger, but its two channels can be disassembled for cleaning, and its application range is wider.
6, Spiral plate heat exchangers can be divided intoPN0.6,1.0,1.6,2.5MPa(Refers to what a single channel can withstandMaxwork pressure). According to material, it can be divided into carbon steel and stainless steel. Users can choose according to actual process conditions.
7. When a single device cannot meet the usage requirements, multiple devices can be used in combination, but the combination must comply with the following regulations: parallel combination, series combination, and the spacing between devices and channels is the same. Mixed combination: One channel in parallel and one channel in series.
