本装置适用于制药、食品、轻工、化工等行业的稀酒精回收。也适用于甲醇等其他溶媒的蒸馏。本装置根据用户的要求，可将30℃左右的稀酒精蒸馏至90℃-95℃酒精，成品酒精度要求越高，可加大回流比，但产量则相应降低。W型也可用于甲醇等蒸馏。W型为间歇式，ZW型为连。
This device is suitable for pharmaceutical, foodstuff, light industry, chemical industry such as thin alcohol recovery. Can also be applied to other solvent of methanol distillation. This device according to the requirement of the user, can dilute alcohol distillation is about 30 ℃ to 90 ℃ to 95 ℃ alcohol, finished product requires the higher alcohol content, can increase the reflux ratio, but production is reduced. W type can also be used for methanol distillation. W is intermittent, ZW type for even.
