Non-separable horizontal spiral plate heat exchanger

Non-separable horizontal spiral plate heat exchanger

Product Overview

A spiral plate heat exchanger is a heat exchange device suitable for gas-gas, gas-liquid, and liquid-liquid heat transfer, as well as for condensation and liquid evaporation. This product boasts high heat transfer efficiency, strong self-cleaning ability against scaling, compact size, affordable price, and reliable operation. It is used in industries such as chemicals, petrochemicals, solvents, food, light industry, textiles, metallurgy, rolling steel, and coking. It can be classified into non-detachable (Type I) spiral plate heat exchangers and removable (Type II, III) spiral plate heat exchangers based on its structural form.

The nominal pressure PN for spiral plate heat exchangers is specified as 0.6, 1, 1.6, and 2.5 MPa (equivalent to the original 6, 10, 16, and 25 kg/cm²), which refers to the working pressure the single channel can withstand. The test pressure is 1.25 times the working pressure.

Basic Parameters

The material for the contact part of the spiral plate heat exchanger with the medium is carbon steel Q235A, Q235AF, and stainless steel acid steel SUS321, SUS304. Other materials can be selected according to customer requirements.

 Operating Temperature Range: Carbon steel t=0～+350°C, stainless steel acid steel t=-40～500°C, the temperature and pressure reduction range shall comply with relevant regulations for pressure vessels. When selecting this equipment, appropriate process calculations should be made to ensure the fluid in the equipment passage reaches turbulent flow status. (Generally, liquid flow rate 1m/sec, gas flow rate 10m/sec).

A single unit does not meet the usage requirements; multiple units can be combined for use, but the combination must comply with the following regulations:

Parallel and Series Combinations: Same equipment and channel spacing.

Mixed Configuration: One channel in parallel, one channel in series.
