1. This equipment is made up of two rolls, and spiral plate heat exchanger cannot meet the requirements for use. Two uniform spiral channels are formed, and the two heat transfer media can perform full countercurrent flow, which greatly enhances the heat exchange effect, and even two small temperature difference media can achieve the desired heat exchange effect.

2. The connecting tube on the housing adopts a tangential structure, and the local resistance is small. Since the curvature of the spiral passage is uniform, the liquid does not have a large steering in the device, and the total resistance is small, so that the design flow rate can be improved to make it have a higher Heat transfer capacity.

3. The end face of the spiral passage of the type I non-removable spiral plate heat exchanger is welded and sealed, thus having a high sealing property.

4. The structure principle of the Type II detachable spiral plate heat exchanger is basically the same as that of the non-removable heat exchanger, but one of the channels can be disassembled and cleaned, especially suitable for heat exchange with viscous and precipitated liquid.

5. The structure principle of the type III detachable spiral plate heat exchanger is basically the same as that of the non-removable heat exchanger, but the two channels can be disassembled and cleaned, and the scope of application is wide.

It can be used in combination, but the following must be met when combining: parallel combination, series combination, device and channel spacing are the same. Hybrid combination: one channel is connected in parallel and one channel is connected in series
