Spiral plate heat exchanger is the high-efficiency heat exchanger equipment, application of steam - gas, steam - liquid, liquid - liquid, the heat transfer fluid. It applies to the chemical, oil, solvents, medicine, food, light industry, textile, metallurgy, steel rolling and coking sectors. The structure can be divided into non-demolition (I type) spiral plate and removable (II type, III type) spiral plate heat exchanger.
Structure and Properties:
1. The equipment made by the two rolling forms two uniform helical channel, so the two heat transfer media counter-current flow of the whole can be greatly enhanced heat transfer effect, even small temperature difference between the two media, but also achieve the desired the effect of the heat exchanger.
2. In the shell of the structure to take over the use of tangential, local resistance, due to the curvature of the spiral channel is uniform, the liquid flow in the device there are no major shift, with a total resistance of the small, the design flow rate will be enhanced to have more high heat transfer capacity.
3. I-type non-demolition-style spiral plate heat exchanger has a high tightness.
4. The channel of II-type detachable spiral plate heat exchange can be opened to clean, especially sticky, and the heat exchange liquid precipitation.
5. III-type detachable spiral plate heat exchanger has the same structure with spiral plate heat exchanger that can not be removed heat exchanger, but the two channels of it can be opened cleansing and apply to a wider scope.
6. Spiral plate heat exchanger Nominal pressure PN 0.6, 1.0, 1.6, 2.5 Mpa (means of access under the maximum working pressure), according to materials can be divided into carbon steel and stainless steel. Single piece of equipment can not meet the application requirements, you can use more than one portfolio, but the portfolio must meet the following requirements: Parallel combination of series combination of the same equipment and channel spacing. Mixed combination: A channel parallel, a serial channel.
