Spiral Plate Heat Exchanger In Chemical Industry

Sprial plate heat exchanger in chemical Industry

Spiral welded PHE features:

Spiral plate heat exchanger is made by welding two thin metal plates on a dividing plate and rolling them into a spiral shape. The two metal plates form two spiral channels, and a head or cover plate. During heat exchange, the hot and cold fluids enter two channels respectively, and do strict countercurrent flow in the heat exchanger.

Advantage

1. High heat transfer efficiency (good performance)
It is generally believed that the heat transfer efficiency of the spiral plate heat exchanger is 1-3 times that of the tubular heat exchanger. There is no flow dead zone in a single channel of equal cross-section, and the disturbance of the flow by the fixed-space column and the spiral channel reduces the critical Reynolds number of the fluid. The heat transfer coefficient of the spiral plate heat exchanger can reach a maximum of 3000W/(㎡. K).
2. Effective recovery of low temperature heat energy
The spiral plate heat exchanger is made of two rolls for waste heat recovery and full use of low-temperature heat energy.
3. Strong operational reliability
The end face of the spiral channel of the non-detachable spiral plate heat exchanger is welded and sealed, so it has a high sealing performance and ensures that the two working media are not mixed.
4. Low resistance
The nozzle on the housing adopts a tangential structure. Relatively low pressure loss, handle large-capacity steam or gas; have self-cleaning ability, because the medium flows in a spiral shape, dirt is not easy to deposit; easy to clean, can be washed with steam or lye, simple and easy to install, suitable for cleaning devices; The medium takes a single channel, allowing the flow rate to be higher than other heat exchangers.
5. Can be used in combination with multiple units
When a single device cannot meet the use requirements, multiple devices can be used in combination, but the combination must meet the following requirements: parallel combination, series combination, and the same distance between devices and channels. Mixed combination: one channel in parallel, one channel in series.
