Spiral Plate Heat Exchanger
Spiral plate heat exchangers are high-efficiency heat exchange devices suitable for steam-to-steam, steam-to-liquid, and liquid-to-liquid heat transfer. They are used in industries such as chemicals, petrochemicals, solvents, pharmaceuticals, food, light industry, textiles, metallurgy, rolling steel, and coking. They can be categorized into non-detachable (Type I) and detachable (Type II, Type III) spiral plate heat exchangers based on their structural form.
Structure and Performance
1. This equipment is formed from two rolls, creating two even spiral channels. The two heat transfer media can flow in a full counter-current manner, significantly enhancing the heat exchange efficiency. Even with two media with small temperature differences, it can achieve ideal heat exchange results.
2. The接管 on the housing features a tangential structure, resulting in low local resistance. Due to the uniform curvature of the helical channel, there is no significant redirection of fluid flow within the equipment, leading to low total resistance. Consequently, the design flow rate can be increased, enabling higher heat transfer capabilities.
3. The I-type non-detachable spiral plate heat exchanger features a welded seal on the ends of its spiral channels, thus offering high sealing integrity.
4. The structural principle of the II-type single-sided removable spiral plate heat exchanger is basically 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 double-sided removable spiral plate heat exchanger operates on a principle similar to that of non-removable heat exchangers, but its two channels can be...
Disassemble and clean, suitable for a wide range of applications.
6. When a single piece of equipment 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.
