VACUUM DISTILLATION UNIT

摘要

PROBLEM TO BE SOLVED: To provide a vacuum distillation unit whereby a burden concerning maintenance can be alleviated. SOLUTION: A vacuum distillation unit is provided with: a distillation furnace 1 equipped with a heat means K for heating a solution stored to be distilled; a vacuum means 4 for decompressing the inside of the distillation furnace 1 by vacuuming a steam discharge passage 3 connected to the distillation furnace 1; and a condenser 5 for liquefying steam flowing through the steam discharge passage 3. A gas-liquid separation part 30 for separating mist from steam flowing through the steam discharge passage 3 by a specific gravity difference between mist and steam is provided so that the entire body of the part 30 is located above a connection port 1w of the steam discharge passage 3 of the distillation furnace 1 and liquid liquefied from mist separated at the gas-liquid separation part 30 returns to the distillation furnace 1 by the liquid's own weight.
