Description
A spiral plate heat exchanger is a heat exchanger made up of two parallel metal plates rolled into two spiral channels, where the cold and hot fluids exchange heat through the spiral plate walls. There are two types of spiral plate heat exchangers: detachable and non-detachable.
Spiral plate heat exchangers have the advantages of small volume, compact equipment, high heat transfer efficiency, and low metal consumption. They are suitable for dry liquid, gas-liquid, and gas-gas convection heat transfer, steam condensation and liquid evaporation heat transfer, as well as industries such as chemical, petroleum, pharmaceutical, mechanical, electrical, environmental, energy-saving, and requiring heat conversion.
Structure Performance
Countercurrent Flow
It is formed by rolling two plates, forming two uniform spiral channels. The two heat transfer media can perform full countercurrent flow, greatly enhancing the heat transfer effect. Even with two small temperature difference media, the ideal heat transfer effect can be achieved.
Tangential Structure
The connecting pipe on the shell adopts a tangential structure with low local resistance. Due to the uniform curvature of the spiral channel, there is no significant turning of the liquid flow in the equipment, resulting in low overall resistance. Therefore, the design flow rate can be increased to have higher heat transfer capacity.
Type I (Non-detachable)
The end face of the spiral channel of the Type I non-detachable spiral plate heat exchanger is sealed by welding, thus having high sealing performance.
Type II (Detachable One-Channel)
The structural principle of Type II detachable spiral plate heat exchanger is basically the same as that of non-detachable heat exchanger, but one of the channels can be disassembled for cleaning, making it particularly suitable for heat exchange with viscous and precipitated liquids.
Type III (Detachable Two-Channel)
The structural principle of the Type III detachable spiral plate heat exchanger is basically the same as that of a non-detachable heat exchanger, but its two channels can be disassembled for cleaning, making it suitable for a wide range of applications.
Combination Use
When a single device cannot meet the usage requirements, multiple devices can be combined for use, but the combination must comply with the following regulations: parallel combination, series combination, and the spacing between devices and channels is the same. Hybrid combination: one channel in parallel and one channel in series.
