Spiral Plate Heat Exchanger
A spiral plate heat exchanger is an efficient heat exchange equipment suitable for vapor-vapor, vapor-liquid, and liquid-liquid heat transfer. It is used in industries such as chemicals, petroleum, solvents, pharmaceuticals, food, light industry, textiles, metallurgy, rolling steel, and coking. Spiral plate heat exchangers can be categorized into non-detachable (Type I) and detachable (Type II, Type III) based on their structural design.
Structure and Performance
1. This equipment is formed from two rolls, creating two even spiral channels. Both heat transfer mediums can flow in a fully counter-current manner, significantly enhancing the heat exchange efficiency, even for mediums with small temperature differences, achieving ideal heat exchange results.
2. The transition on the housing employs a tangential structure, resulting in low local resistance. Due to the uniform curvature of the helical channel, the fluid flow within the equipment experiences minimal directional changes, leading to low total resistance. Consequently, the design flow rate can be increased, endowing it with high heat transfer capability.
3. The I-type non-detachable spiral plate heat exchanger features a sealed end face with welding, thus offering high sealing performance.
4. The structural principle of the Type II single-sided removable spiral plate heat exchanger is essentially the same as that of the non-removable type, but one channel can be removed for cleaning, particularly suitable for heat exchange with sticky or sedimentary liquids.
5. The III-type reversible spiral plate heat exchanger has a structure and principle that is essentially the same as that of non-reversible heat exchangers, but its two channels can...
Disassembled for cleaning, with a wide range of applicability.
6. When a single piece of equipment does not meet the usage requirements, multiple units can be combined. However, the combination must adhere to the following regulations: parallel combination, series combination, and equal spacing between equipment and channels. Mixed combination: one channel in parallel and one channel in series.
