Background
With the continuous development of modern new processes, new technologies and new materials and the increasing severity of energy problems. The development and application of the efficient and energy-saving heat exchange and separation equipment have important practical significance. Due to the unique structure of the scraping film separator, the scraping plate has a pumping effect, so that the material is prevented from forming walls and scaling on a heating surface, good heat exchange is carried out, and meanwhile, the residence time of the material in the separator is very short; in addition, the product will not remain on the surface of the separator due to the high speed turbulence of the membrane on the heated separator. Therefore, the method is particularly suitable for evaporation of high-viscosity and heat-sensitive materials. The wiped film evaporator has been used in the chemical industry for the purposes of evaporation concentration, desolventizing, stripping, reaction, degassing, deodorizing (odor) and the like, and has achieved good results.
At present, most of the scraped membrane separators are applied to industrial mass production, and the research and development of the scraped membrane separators applied to chemical laboratories are relatively blank. Meanwhile, the research on the enhanced heat transfer technology of the scraped membrane separator has very far-reaching guiding significance on energy conservation.
At present, the main distillation equipment in the chemical laboratory is as follows: rectifying column and rotary evaporator. The rectifying tower can carry out rectification with high precision, but has long rectifying time, large occupied area and high price, and cannot be continuously produced; the rotary evaporator has the advantages that due to the centripetal force and friction force between the liquid sample and the evaporation bottle, the liquid sample forms a layer of liquid film on the inner surface of the evaporation bottle, the heating area is large, manual operation is needed, only crude distillation is needed, and the rectification is needed to be matched with a rectifying tower.
