Stainless steel spiral plate heat exchanger is a high-efficiency heat transfer equipment, applicable for steam-to-steam, steam-to-liquid and liquid-to-liquid heat transfer. It is widely used in chemical, petroleum, solvent, pharmaceutical, food, light industry, textile, metallurgy, steel rolling, coking and other industries. According to structural form, it can be divided into non-detachable (Type I) spiral plate heat exchangers and detachable (Type II, Type III) spiral plate heat exchangers.

Structure & Performance

1. This equipment is fabricated by rolling two metal plates to form two uniform spiral channels. The two heat transfer media can flow in full counter-current mode, which greatly enhances heat exchange efficiency. Ideal heat transfer performance can be achieved even for media with small temperature difference.

2. The nozzles on the shell adopt tangential configuration with low local resistance. Thanks to the uniform curvature of spiral channels, the fluid flows without sharp turns inside the equipment, resulting in low overall resistance. Therefore, higher design flow velocity can be adopted to obtain superior heat transfer capacity.

3. The end faces of spiral channels of Type I non-detachable spiral plate heat exchanger are sealed by welding, delivering high sealing performance.

4. Type II detachable spiral plate heat exchanger shares basically the same structural principle as the non-detachable type, while one channel can be disassembled for cleaning. It is especially suitable for heat exchange of viscous or sediment-containing liquids.

5. Type III detachable spiral plate heat exchanger has basically the same structural principle as the non-detachable type, but both channels can be disassembled for cleaning, featuring a wider range of applications.

6. Spiral plate heat exchangers are classified by nominal pressure into PN0.6, 1.0, 1.6, 2.5 MPa (referring to the maximum working pressure a single channel can withstand). By material, they are carbon steel and stainless steel. Customers can select according to actual process conditions.

7. When a single unit cannot meet operating requirements, multiple units can be combined for use, subject to the following provisions:

Parallel combination or series combination: identical equipment and identical channel gap. Mixed combination: one channel in parallel and the other in series.
