Abstract
The utility model discloses a methanol recovery device comprising a distillation tower, wherein a liquid inlet of the distillation tower is communicated with a heat exchanger which is communicated with a steam pipeline, a drain outlet of the distillation tower is communicated with the heat exchanger, a medium inlet of the heat exchanger is connected with a neutralizing centrifugal liquid delivery pipe, a medium outlet of the heat exchanger is connected with the medium inlet of the heat exchanger, and a working medium inlet of the heat exchanger is connected with a waste liquid outlet of the distillation tower. When waste liquid is discharged, the waste liquid firstly flows through the heat exchanger to exchange heat with neutralizing centrifugal liquid, so as to enable the temperature of the neutralizing centrifugal liquid to be increased from about 25 DEG C to 45-50 DEG C, and then the neutralizing centrifugal liquid enters the distillation tower for distillation after being heated to be boiling by a primary heat exchanger and a secondary heat exchanger. By fully utilizing the heat of the waste liquid after distillation, the heating time is shortened, not only the purposes of saving energy and reducing consumption are achieved, but also the efficiency and unit output of methanol distillation recovery are improved simultaneously.
