Spiral plate heat exchangers |
Helical-plate heat exchanger is a high efficiency device used for vapor-vapor, vapor-liquid, liquid-liquid heat exchanging in chemistry, petrol, solutions, pharmaceutics, food, light industry, textile, metallurgy, steel rolling, coking and other industries. It can be categorized as inseparable helical-plate type (I type) and separable type (II type and III type) heat exchangers.
|
Structure and performance
1. This device is made by rolling to have produced two even helical tubes through which two heat media can full counterflow, enhancing heat exchanging effect. Even with two media of small temp. difference, it also accomplish ideal effect.
2. The body is designed with small resistance. Liquids will not meet sharp turns due to even bend rate of the tube to have reduced resistance, so that the design speed can be raised to reach better exchanging capability.
3. I type inseparable helical exchanger is designed with welded sealing on the end surface of tube, which means excellent tightness.
4. The structural theory of II type separable exchangers is basically the same as that of inseparable one, except that one tube can be disassembled for cleaning, applicable for high viscosity liquids and those with sediment.
5. The structural theory of II type separable exchangers is basically the same as that of inseparable one, except that two tubes can be disassembled for cleaning, applicable for a wider range.
6. The helical exchangers can be divided into PN0.6, 1.0, 1.6 and 2.5MPa (referring to max. bearable working pressure for single tube) according to nominal rating, or carbon steel and stainless steel according to materials. Users can choose according to actual technique parameters.
7. When single set of device is not satisfactory, combination of multiple sets can be used under the following conditions:
Same distance between parallel combination, in-series combination, device and tubes. Mixed connection with one tube parallel and other in series. |
