Abstract

DC60 (07/03/49) It is the purpose of this invention. In the case of devices where liquids Which has a material with a point Boiling below the boiling point of the liquid Is made to flow down the outer surface of the conductor During which time Materials with lower boiling points are evaporated. To prepare Specific equipment That can be operated stably for a long time On an industrial scale In such a way that not less than 1 t / h of the liquid is passed on to evaporation and, furthermore, to prepare a device for evaporation. Specific industry where there are no problems due to The decay that is caused by Some of the liquid that has lived in the device for a long time. The present inventor has achieved This invention with the discovery that The above objectives can be achieved and the concentrated liquid or condensed polymer or high purity thermoplastic polymer can be easily obtained by using equipment for the This makes industrial evaporators with a unique structure where there is no conductor to heat by itself. Parts for control Flow path Which has the function of making the liquid feed on The perforated plate from the door receives most of the liquid from the periphery. To the middle part of the perforated sheet Was prepared In the area for liquid entry and formulas (1) to (5) or formulas (1) to (10) or formulas (1) to (12) are complied with. It is the purpose of this invention.
