Spiral Plate Heat Exchanger

Overview

A spiral plate heat exchanger is a heat exchange equipment suitable for vapor-vapor, vapor-liquid, and liquid-liquid heat transfer for liquids. It is used in industries such as chemicals, petrochemicals, solvents, food, light industry, textiles, metallurgy, rolling steel, and coking. It can be divided into non-detachable (Type I) and removable (Type II, Type III) spiral plate heat exchangers according to its structural form.

       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 fully counter-current manner, significantly enhancing the heat exchange efficiency. Even with two mediums having 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, there is no significant change in direction of the liquid flow within the equipment, resulting in lower overall resistance. Consequently, the design flow rate can be increased, enabling higher heat transfer capabilities.
3. The I-type non-separable helical plate heat exchanger features a sealing surface with welding, thus ensuring high sealing integrity.
4. The structural principle of the Type II removable spiral plate heat exchanger is essentially the same as that of the non-removable type, but one of the channels can be disassembled for cleaning, making it particularly suitable for heat exchange with sticky or sediment-containing liquids.
5. The III-type removable spiral plate heat exchanger operates on the same principle as the non-removable type, but its two channels can be disassembled for cleaning, making it more versatile in application.
6. Spiral plate heat exchangers can be categorized by nominal pressure into PN0.6, 1.0, 1.6, and 2.5 MPa (referring to the maximum working pressure a single channel can withstand). They can also be divided by material into carbon steel and stainless steel. Users can select according to their actual process conditions.
7. In cases where a single piece of equipment does not meet the usage requirements, multiple units can be combined. However, when combining, the following regulations must be adhered to: parallel combination, series combination, and equal spacing between equipment and channels. Mixed combination: one channel in parallel and one channel in series.
