Claims

[Claims for Utility Model Registration] 1. The recovery section and concentration section of a distillation column are each configured as a tray column independent of each other, and between the recovery section and concentration section, the steam emitted from the top of the column of the recovery section is pressurized. A pressurizing pipe is provided with a pressurizing means for feeding the liquid into the bottom of the concentrating section, and a reducing pipe is equipped with a reducing means to reduce the pressure of the liquid at the bottom of the concentrating section and return it to the top of the recovery section. In a distillation apparatus configured to perform heat exchange between the concentration section and the recovery section, the recovery section and the concentration section are arranged concentrically so that one is an inner column and the other is an outer column. A distillation column with a double column structure is constructed in which the concentration section and the recovery section are in contact with each other via a heat transfer wall, and a liquid guide section is provided in the recovery section to guide the liquid on the tray to the tray below. The liquid guide section is characterized by comprising a flow section that allows the liquid to flow down along the heat transfer wall, and an overflow section that rises from the lower end of the flow section and causes the liquid to overflow. Distillation equipment. 2. The distillation apparatus according to claim 1, further comprising a steam guide member provided in the concentrating section to guide the vapor in the concentrating section toward a heat transfer wall.
