Spiral plate heat exchanger Two spiral channels are made of two parallel metal plates, and heat exchange between cold and hot fluids is conducted through spiral plate walls. There are two types of spiral plate heat exchanger: detachable and non detachable.

Structural performance:

1. This equipment is applicable to: liquid-liquid, gas-liquid, gas-liquid convection heat transfer can be used for steam condensation and liquid evaporation heat transfer, chemical, petroleum, medicine, machinery, power, light industry, textile and other industrial sectors can choose.

2. This equipment is made of two rolled steel plates, forming two uniform spiral channels. The two heat transfer cut-off can carry out full countercurrent flow, and is suitable for heat transfer with small temperature difference, so as to facilitate the recovery of low temperature heat sources and accurately control the outlet temperature.

3. The nozzle on the shell is a tangential structure, with small local resistance, uniform curvature of the spiral channel, no large reversal of fluid flow in the equipment, and small total resistance. Therefore, the design flow rate can be increased to have a high heat transfer capacity.

4. The end face of the spiral channel is welded and sealed, with good sealing performance and reliable structure.

5. The nominal pressure PN of the spiral plate heat exchanger is specified as 0.6, 1, 1.6, 2.5 Mpa (that is, the original 6, 10, 16, 25 kg/cm2). The test pressure is 1.25 times of the working pressure.

6. Single equipment cannot meet the use requirements, and multiple equipment can be used in combination, but the combination must meet the following requirements: parallel combination, series combination: the distance between equipment and channel is the same. Mixed combination: one channel is in parallel and one channel is in series.
