Detachable Spiral Plate Heat Exchanger
Product Overview
Spiral plate heat exchangers are a type of heat exchange equipment suitable for gas-gas, gas-liquid, and liquid-liquid applications, as well as for condensation and liquid evaporation heat transfer. This product boasts high heat transfer efficiency, strong self-cleaning ability against fouling, compact size, affordable price, and reliable performance. It is used in industries such as chemicals, petroleum, solvents, food, light industry, textiles, metallurgy, rolling, and coking. Structurally, they can be classified into non-detachable (Type I) spiral plate heat exchangers and removable (Type II, III) spiral plate heat exchangers.
The nominal pressure PN for spiral plate heat exchangers is specified as 0.6, 1, 1.6, and 2.5 MPa (equivalent to original 6, 10, 16, and 25 kg/cm²), which refers to the working pressure that 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 acid steel SUS321, SUS304. Other materials can be selected according to customer requirements.
Operating Temperature Range: Carbon steel: t=0～+350°C, stainless steel and acid-resistant steel: t=-40～500°C, the temperature and pressure reduction range shall comply with the relevant regulations for pressure vessels. When selecting this equipment, appropriate process calculations should be made to ensure the fluid in the equipment channel reaches turbulent flow. (Typically, liquid velocity 1m/Sec, gas velocity 10m/Sec).
Single units may not meet the usage requirements, but can be combined in multiple units. However, 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.
