Abstract
This utility model discloses a dehydration distillation column for regenerating waste stripping liquid, specifically relating to the field of waste stripping liquid regeneration technology. It includes a distillation column body, with a liquid inlet pipe fixed to the top and bottom of the outer wall of the column body, respectively. Both the liquid inlet pipe and the gas inlet pipe extend into the interior of the distillation column body. The interior of the distillation column body has multiple trays arranged vertically. Two conical flow dividers are also located vertically within the column body, positioned at the top of the gas inlet pipe and the bottom of the liquid inlet pipe, respectively. Two flow divider plates are positioned between the two conical flow dividers, located at the top and bottom of the multiple trays, respectively. Each flow divider plate has multiple flow channels penetrating through it. This utility model improves distillation efficiency by performing multiple flow divisions of the gas and liquid phases and increasing the flow rate, thereby increasing the contact area between the gas and liquid phases.
