The structural performance of the spiral plate heat exchanger
Jan 23, 2021

1 It is made of two rolls to form two uniform spiral channels. The two heat transfer media can flow in full countercurrent flow, which greatly enhances the heat exchange effect. 2 The connecting pipe on the shell adopts a tangential structure, and the local resistance is small. Because the curvature of the spiral channel is uniform, the liquid flows in the equipment without big turning, and the resistance is small, so the design flow rate can be increased to make it have a higher transmission rate. Thermal capacity. The end surface of the spiral channel of the 3I type non-detachable spiral plate heat exchanger is sealed by welding, which has high sealing performance. The structure principle of 4II type detachable spiral plate heat exchanger is basically the same as that of non-detachable heat exchanger, but one of the channels can be detached for cleaning, which is especially suitable for heat exchange with viscous and precipitated liquid. The structure principle of the 5III detachable spiral plate heat exchanger is basically the same as that of the non-detachable heat exchanger, and it has a wide range of applications. 6 When a single device cannot meet the requirements for use, multiple devices can be used in combination, but the following requirements must be met when combined: parallel combination, series combination, and the same distance between devices and channels. Mixed combination: One channel is connected in parallel and one channel is connected in series.
