Spiral plate heat exchanger is a highly efficient heat transfer equipment for gas - gas, gas - liquid, liquid - liquid, the liquid heat transfer. It is suitable for chemical, oil, solvents, pharmaceuticals, food, light industry, textile, metallurgy, steel rolling, coking and other industries. Form of the structure can be divided into non-split type (I type) spiral plate and the removable (Ⅱ type, Ⅲ type) spiral plate heat exchanger.
Structure and Properties
1, the device consists of two volumes from the system, the formation of two uniform helical channel, the two heat transfer media can be wholly counter-current flow, which greatly enhances the effect of heat transfer, even a small temperature difference between the two media, but also to achieve the desired The effect of heat transfer.
2, in case the takeover by the tangential structure, local resistance, the curvature of the spiral channel is uniform, the liquid flow in the device there are no major shift, the total resistance, which can improve the design flow so that with more High heat capacity.
3, I-type can not be demolished spiral heat exchanger spiral welded seal the ends of channels, which have a high tightness.
4, Ⅱ-type detachable spiral plate heat exchanger and can not be demolished structure principle is basically the same heat exchanger, but one can open the clean channel, especially for a viscous, heat exchange liquid precipitation.
5, Ⅲ type detachable spiral plate heat exchanger principle and not demolished the structure heat exchanger is basically the same, but the two channels can open the cleaning of wider application.
6, spiral plate heat exchanger can be divided by the nominal pressure PN0.6, 1.0,1.6,2.5 MPa (mean channel can withstand the maximum working pressure). Press material can be divided into carbon steel and stainless steel. Users can choose according to the actual process conditions.
7, the single piece of equipment can not meet the requirements, you can use multiple combinations, but the combination must meet the following requirements:
Parallel combination of series combination, the same equipment and channel spacing. Hybrid combination: a channel parallel, a channel series.
