Spiral plate heat exchanger 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 fully countercurrent manner, significantly enhancing the heat exchange efficiency. Even with two media with small temperature differences, it can achieve a suitable heat exchange effect.

        2. The pipe connections on the housing are designed with a tangential structure, which minimizes local resistance. Due to the uniform curvature of the helical channels, the fluid flow within the equipment experiences minimal direction changes, resulting in lower total resistance. Consequently, the design flow rate can be increased, enabling the device to have a higher heat transfer capability.

        3. The I-type non-detachable spiral plate heat exchanger features a sealed end face with welding, ensuring high sealing integrity.

        4. The structural principle of the II-type removable spiral plate heat exchanger is essentially the same as that of the non-removable type, but one channel can be disassembled for cleaning, making it particularly suitable for heat exchange with sticky or sedimentary liquids.

        5. The III-type removable spiral plate heat exchanger operates on the same structural principle as non-removable heat exchangers, but its two channels can be disassembled for cleaning, making it more versatile in application.

        6. Spiral plate heat exchangers are divided into PN0.6, 1.0, 1.6, and 2.5 MPa (referring to the maximum working pressure a single channel can withstand) based on nominal pressure. They can also be categorized into carbon steel and stainless steel according to material. Users can select according to their actual process requirements.

        7. 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 connection, series connection, and equal spacing between equipment and pathways. Mixed connection: one channel in parallel and one channel in series.
