Detachable spiral plate heat exchanger

Detachable Spiral Plate Heat Exchanger

Product Overview

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

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 that a 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 flow rate of 1m/Sec, gas flow rate of 10m/Sec).

A single unit does not meet the usage requirements; multiple units can be combined for use, but the following regulations must be adhered to when combining:

Parallel and Series Combinations: Same spacing between equipment and channels.

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