Spiral Plate Heat Exchanger
A spiral plate heat exchanger is an efficient heat exchange device suitable for heat transfer between steam-gas, steam-liquid, and liquid-liquid. It is used in industries such as chemicals, petroleum, solvents, pharmaceuticals, food, light industry, textiles, metallurgy, rolling steel, and coking. It can be divided into non-detachable (Type I) spiral plate heat exchangers and detachable (Type II, Type III) spiral plate heat exchangers according to the structural form.
Structure and Performance
1. This equipment is formed from two rolls, creating two uniform spiral channels. The two heat transfer mediums can flow in full counter-current, significantly enhancing the heat exchange efficiency. Even with two mediums with small temperature differences, ideal heat exchange results can be achieved.
2. The branch connections on the housing are designed with a tangential structure, resulting in low local resistance. Due to the uniform curvature of the helical channels, the liquid flow within the equipment experiences minimal direction changes, leading to reduced overall 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 sealed ends in its spiral channels, thereby offering high sealing performance.
4. The structure and principle of the Type II single-sided removable spiral plate heat exchanger are essentially the same as those of the non-removable type, but one channel can be removed for cleaning, making it particularly suitable for heat exchange with sticky or sedimentary liquids.
5. The structure and principle of the III reversible double-sided spiral plate heat exchanger are essentially the same as those of the non-reversible heat exchanger, but its two channels can
Disassembled and cleaned, with a wide range of applications.
6. When a single piece of equipment does not meet the usage requirements, multiple units can be combined. However, the following regulations must be adhered to when combining: parallel combination, series combination, and equal spacing between equipment and channels. Mixed combination: one channel in parallel and one channel in series.
