Vapor separation method and vapor separation device for mixed liquid, and recovery device for vaporized and separated liquid

摘要

When a high vapor pressure liquid is vaporized and separated from a liquid mixture of two liquid mixtures in which the vapor pressures of a low vapor pressure liquid and a high vapor pressure liquid are different from each other, bumping is performed while flowing the mixed liquid through an inclined channel. The liquid separation method and vaporization separation device, and the vaporized and separated liquid recovery device that can separate and recover both of the two liquids so that they can be reused easily and efficiently without occurrence I will provide a. A method of vaporizing and separating only a cleaning liquid from a two-liquid mixed liquid M in which the vapor pressures of quenching oil D and cleaning liquid C are different from each other. In an initial stage of maintaining the first pressure higher than that, the mixed liquid begins to flow by gravity from the start end 14a to the end 14b of the inclined flow path 14 inside the distiller, and then the mixed liquid reaches the end of the inclined flow path. Upon arrival, the internal pressure of the still is reduced and maintained from the first pressure to a second pressure that is lower than the vapor pressure of the cleaning liquid and higher than the vapor pressure of the quenching oil.
