[0022] In this embodiment, a steam valve 41 is installed on the steam inlet pipe 4 to facilitate the entry of steam.

[0023] Specifically, a base 13 is installed at the bottom of the outer drum 12, and a steam pipe 121 is connected to one side of the bottom of the outer drum 12. The outer end of the steam pipe 121 is connected to the bottom end of the steam inlet pipe 4 to facilitate the entry of steam.

[0024] Furthermore, a pressure gauge 16 and a thermometer 17 are connected to the outer side of the inner drum 11 to facilitate measuring the air pressure and temperature of the inner drum 11 .

[0025] Furthermore, an air outlet pipe 15 is provided at the top of the distillation tower 1, and the air outlet pipe 15 is connected to one end of the riser 3, and an air inlet pipe 24 is connected to the other end of the riser 3, so as to facilitate the discharge of steam.

[0028] When the lees distillation device of the utility model is used, first, the lees are placed in the inner drum 11 of the distillation tower 1. Then, steam is introduced into the heating layer through the steam inlet pipe 4, and the steam is evenly distributed in the heating layer to provide a uniform and stable heat source for the lees in the inner drum 11. As the temperature rises, the alcohol and other volatile components in the lees begin to vaporize to form distillation gas.

[0029] The distilled gas is then guided to the cooling tower 2 through the outlet pipe 15 and the riser 3 at the top of the distillation tower 1. In the cooling tower 2, the distilled gas exchanges heat with cooling water through the heat exchange pipe, thereby achieving rapid cooling.

The sewage pipe 14 is used to discharge the sewage and waste residue in the inner drum 11 in time to keep the equipment clean and running efficiently.
