Spiral Plate Heat Exchanger
A spiral plate heat exchanger is an efficient heat exchange equipment suitable for steam-to-steam, steam-to-liquid, and liquid-to-liquid heat transfer. It is used in industries such as chemicals, oil, solvents, pharmaceuticals, food, light industry, textiles, metallurgy, rolling steel, and coking. Spiral plate heat exchangers can be categorized by structure into non-detachable (Type I) and removable (Type II, III) spiral plate heat exchangers.
Structure and Performance
1. This equipment is formed from two rolled sheets, creating two even spiral channels. Both heat transfer mediums can flow in a fully counter-current manner, significantly enhancing the heat exchange efficiency. Even with two mediums having small temperature differences, it achieves ideal heat exchange results.
2. The transition on the housing is designed with a tangential structure, featuring low local resistance. Due to the uniform curvature of the helical channel, the fluid flow within the equipment experiences minimal directional changes, resulting in low total resistance. Consequently, the design flow rate can be increased, enhancing the heat transfer capacity.
3. The I-type non-detachable spiral plate heat exchanger features a sealed end face with welding, thus offering high sealing performance.
4. The II-type single-sided removable spiral plate heat exchanger operates on the same principle as non-removable heat exchangers, but one channel can be removed for cleaning, making it particularly suitable for heat exchange of sticky or sediment-containing liquids.
5. The structure and principle of the III-type two-sided removable spiral plate heat exchanger is essentially the same as that of the non-removable type, but its two channels can
Disassemble and clean, wide application range.
6. When a single unit does not meet the usage requirements, multiple units can be combined, but the following regulations must be adhered to during combination: parallel combination, series combination, and the same spacing between equipment and channels. Mixed combination: one channel in parallel and one channel in series.
