Description

technical field [0001] The present invention relates to a kind of equipment and method utilizing gas stripping and condensation of steam, especially relates to a kind of equipment and method of heat-sensitive material separation. Background technique [0002] Heat-sensitive materials widely exist in industrial production and daily life. They are unstable to temperature. They will coke, carbonize and be easily oxidized when heated for a long time. This property brings great difficulty to the separation of heat-sensitive materials. In industrial production and daily life, we often encounter heat-sensitive substances, such as many organic monomers and intermediates, fine chemical products, medicines, spices, etc. In order to reduce the heating temperature of heat-sensitive materials and prevent heat-sensitive materials from decomposing or polymerizing and deteriorating at high temperatures, there are many studies on the separation and purification of heat-sensitive materials at...

AI Technical Summary

Problems solved by technology

In order to reduce the heating temperature of heat-sensitive materials and prevent heat-sensitive materials from decomposing or polymerizing and deteriorating at high temperatures, there are many studies on the separation and purification of heat-sensitive materials at home and abroad, and there are many separation methods, such as vacuum distillation, molecular distillation, and chromatographic separation. and other methods, but the separation effect is not good, and the cost is high, most of the methods are not suitable for industrial large-scale production and use
