Controlling condensation in combination with evaporation

摘要

There is provided a liquid condensation system including liquid condensers (10) which evaporates a volatile component of a liquid to be processed under a decompressed atmosphere to condense the liquid, and the system includes: decompressing means (103) which decompresses the inside of each liquid condenser; heating means (94) which is provided for separating the volatile component from the liquid to be processed in each liquid condenser; and cooling means (96) which cools the component volatilized from the liquid to be processed. Each liquid condenser has a triple-pipe structure configured by arranging three pipes (11, 30, 31) with different diameters, the heating means (94) can supply a high-temperature heating medium to a space surrounded by an outer pipe and an intermediate pipe, and the decompressing means can decompress a space between the intermediate pipe and an inner pipe and the inside of the inner pipe.
