Structural performance and application of spiral plate heat exchanger

Performance characteristics and applications of spiral plate heat exchanger:

The heat transfer element consists of a spiral-shaped plate heat exchanger. Spiral plate heat exchanger is a kind of high-efficiency heat exchanger equipment, suitable for steam - steam, steam - liquid, liquid - liquid, to liquid heat transfer. It is suitable for chemical, petroleum, solvent, pharmaceutical, food, light industry, textile, metallurgy, steel rolling, coking and other industries. According to the structure form can be divided into non-detachable (Type I) spiral plate type and detachable (Type II, Type III) spiral plate heat exchanger.

Spiral plate heat exchanger structure performance and application

Spiral plate heat exchanger structure and performance:

1、This equipment is made of two rolled sheets, forming two uniform spiral channels, the two heat transfer media can be full countercurrent flow, greatly enhancing the heat transfer effect, even if the two small temperature difference between the media, but also to achieve the ideal heat transfer effect.

2、The receiver on the shell adopts the tangential structure, the local resistance is small, because the curvature of the spiral channel is uniform, the liquid flows in the equipment without a large turn, the total resistance is small, thus the design flow rate can be increased to make it have a high heat transfer capacity.

3、I-type non-detachable spiral plate heat exchanger spiral channel end face using welded seal, and thus has a high degree of sealing.

Structural performance and application of spiral plate heat exchanger

4、Type II detachable spiral plate heat exchanger structure principle and non-detachable heat exchanger is basically the same, but one of the channels can be disassembled for cleaning, especially for viscous, sedimented liquid heat exchange.

5、Type III detachable spiral plate heat exchanger structure principle and non-detachable heat exchanger is basically the same, but its two channels can be disassembled for cleaning, a wider range of applications.

6, a single device can not meet the requirements of use, you can use more than one combination, but the combination must comply with the following provisions: parallel combination, series combination, equipment and channel spacing is the same. Mixed combination: a channel in parallel, a channel in series.
