Spiral plate heat exchanger

Detachable (Type II, Type III) spiral plate heat exchanger:
The structural principle is basically the same as that of a non detachable heat exchanger, but the channels can be disassembled for cleaning and sealed with heads at both ends. Especially suitable for liquid to liquid exchange with viscous and precipitated liquids, as well as gas-liquid and vapor condensation. Due to the need to add components such as heads and flanges to detachable heat exchangers, the equipment cost is slightly higher than that of non detachable heat exchangers.

Basic parameters:
The nominal pressure PN of the spiral plate heat exchanger is specified as 0.6, 1, 1.6, and 2.5 Mpa (i.e. the original 6, 10, 16, and 25 kg/cm2) (referring to the maximum working pressure of a single channel). The test pressure is 1.25 times the working pressure.
The material of the contact part between the spiral plate heat exchanger and the medium is Q235A and Q235AF carbon steel, and SUS321 and SUS304 stainless steel acid steel. Other materials can be selected according to user requirements.
Allowable working temperature: t=0~+350 ℃ for carbon steel, t=-40~500 ℃ for stainless steel acid steel, and the temperature and pressure range shall be in accordance with the relevant regulations for pressure vessels. When selecting this equipment, appropriate process calculations should be carried out to achieve turbulent flow in the fluid channel of the equipment. (Generally, the liquid flow rate is 1m/Sec and the gas flow rate is 10m/Sec).
A single device cannot meet the usage requirements, and multiple devices can be combined for use, but the combination must comply with the following regulations:
Parallel combination, series combination: equipment and channel spacing are the same. Mixed combination: one channel in parallel and one channel in series.
