SOLVENT REPRODUCTION DEVICE

To efficiently reproduce a solvent through distillation.SOLUTION: A solvent reproduction device is formed, interposing a partition wall 16, with: a distillation tank 14 which has heaters 23 therein, and to which used solvents Sx are introduced; and a collection tank 15 which has, at a bottom part, a high boiling point solvent collecting part 31 and a low boiling point solvent collecting part 32 for respectively collecting two kinds of solvents which have, a difference in boiling points thereof, out of the used solvents Sx. On a part of the partition wall 16, there is formed a flow-down plate part 16a that makes fluid flow down to one side, and defines the distillation tank 14 on the lower side and the collection tank 15 on the upper side. The high boiling point solvent collecting part 31 is formed adjacent to a lower side of the flow down plate part 16a, and a cooling coil 36 is provided on a position except for an upper side of the flow-down plate part 16a and the high boiling point solvent collecting part 31 on the upper part of the collection tank 15, and below the cooling coil, the low boiling point solvent collecting part 32 is provided. On a front stage of the flow-down plate part 16a on the collection tank 15, there is formed an introduction hole 34 into which a solvent to be reproduced, is introduced.SELECTED DRAWING: Figure 1 【課題】蒸留による溶剤の再生を効率よく行う。【解決手段】内部にヒータ２３を有し使用済み溶剤Ｓｘが導入される蒸留槽１４と、使用済み溶剤Ｓｘのうち沸点に高低差のある２種の溶剤をそれぞれ回収する高沸点溶剤回収部３１及び低沸点溶剤回収部３２を下部に有する回収槽１５を、隔壁１６を介して形成する。隔壁１６の一部に、下側を蒸留槽１４、上側を回収槽１５として流体を一方へ流下させる流下板部１６ａを形成する。高沸点溶剤回収部３１は流下板部１６ａの下に隣接して形成し、回収槽１５の上部における流下板部１６ａと高沸点溶剤回収部３１の上方を除く位置に冷却コイル３６を設け、この下方に低沸点溶剤回収部３２を形成する。回収槽１５における流下板部１６ａの前段には再生処理する溶剤を導入する導入口３４を形成する。【選択図】図１
