Spiral Plate Heat Exchanger
A spiral plate heat exchanger is an efficient heat exchange device suitable for steam-steam, steam-liquid, and liquid-liquid heat transfer. It is used in industries such as chemicals, petrochemicals, 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 forms.
Structure and Performance
1. This equipment is formed from two rolls, creating two even spiral channels. The two heat transfer mediums can flow in a full counter-current manner, significantly enhancing the heat exchange efficiency. Even with two mediums of small temperature differences, it can achieve ideal heat exchange results.
2. The transition on the housing is designed with a tangential structure, which minimizes local resistance. Due to the uniform curvature of the helical channel, the fluid flow within the equipment experiences minimal directional changes, resulting in lower total resistance. Consequently, the design flow rate can be increased, enhancing the heat transfer capacity.
3. The I-type non-detachable helical plate heat exchanger features a welding-sealed end surface in its helical channels, thereby ensuring high sealing integrity.
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 disassembled for cleaning, particularly suitable for heat exchange with sticky or sedimentary liquids.
5. The structure and principle of the III-type double-sided removable spiral plate heat exchanger are basically the same as those of the non-removable heat exchanger, but its two channels can
Disassemble and clean, suitable for a wide range of applications.
6. When a single unit does not meet the usage requirements, multiple units can be combined, but they must comply with the following regulations: parallel combination, series combination, and equal spacing between equipment and pathways. Mixed combination: one channel in parallel and one channel in series.
