Structure and Performance of Spiral Plate Heat Exchanger

Structure and Performance of Spiral Plate Heat Exchanger


1, the device is made of two rolling, forming two uniform spiral channel, two kinds of heat transfer medium can be countercurrent flow, greatly enhanced the heat transfer effect, even if the two small temperature difference medium, can achieve the ideal Of the heat transfer effect.
2, the shell on the shell with a tangential structure, local resistance is small, because the spiral channel curvature is uniform, the liquid flow in the device without a large turn, the total resistance is small, which can improve the design flow to make it more High heat transfer capacity.
3, I-type non-removable spiral plate heat exchanger spiral channel of the end of the use of welding seal, which has a high sealing.
4, II-type removable spiral plate heat exchanger structure and non-removable heat exchanger is basically the same, but one of the channels can be opened to clean, especially for a sticky, precipitation of liquid heat exchange.
5, III removable screw plate heat exchanger structure and non-removable heat exchanger is basically the same, but the two channels can be opened to clean, wider range of applications.
6, a single device can not meet the requirements, can be used in multiple combinations, but the combination must meet the following requirements: parallel combination, series combination, equipment and channel spacing the same. Mixing combination: a channel in parallel, a channel in series.

The superheat of the steam of the stainless steel plate heat exchanger has a great influence on the service life of the rubber gasket. It is normally used at 150 ℃ -180 ℃ saturated steam rubber pressure gasket, its use period is 3-5 years or longer, ° C in the superheated steam in the life of only a few months. This is because the saturated vapor in the gasket surface to generate a layer of water film, at high temperatures on the gasket from the effective protection. Therefore, the use of steam not only to pay attention to whether its temperature is suitable for gaskets, superheat is an important factor can not be ignored.
