<p>A distillation device having fewer instrumentation parts to simplify control, comprising partitions (22 to 24) which divide a tower main body to form first chambers (14A to 16A) and second chambers (14B to 16B) adjacent to each other, respectively, a first distillation part (25) having a concentration part at its upper part and a recovery part at its lower part, a second distillation part (26) disposed on the tower main body at a position adjacent to a tower top, and a third distillation part (27) disposed on the tower main body at a position adjacent to the bottom of the tower main body, wherein the partitions are positioned eccentrically so that the cross-sectional areas of the first chambers are different from the cross-sectional areas of the second chambers, respectively, so as to equalize a pressure loss produced in the first chambers to that produced in the second chambers, whereby rising steam is not affected by lowering liquid.</p> |
