Multi-stage sub-boiling distillation integrated system

Abstract

The invention belongs to the technical field of chemical separation equipment, particularly relates to a multi-stage sub-boiling distillation integrated system, and provides the following scheme aiming at the problems that the existing distillation equipment is only limited to laboratory scale research, very low in yield and not suitable for industrialization in the use process: the multi-stage sub-boiling distillation integrated system comprises a tower body, and the tower body is arranged into a four-section type; the plurality of tower plates are arranged in the tower body in a staggered manner, the tops of the plurality of tower plates are connected with a plurality of cylindrical pipes, and the tower plate close to one side of the inner wall of the tower body is connected with the wall surface through a fillet to transition a liquid film on the upper layer along the wall; a plurality of sub-boiling distillators are integrated into a multi-stage tower structure, a high-efficiency gas-liquid separation effect is realized by utilizing treatment of round corners, a structure of a cylindrical pipe, an arc-shaped drainage supporting plate and a net-shaped filler and a multi-stage reflux system, and meanwhile, accurate adjustment of a heating process is ensured by an intelligent temperature control system; the whole device has the advantages of being energy-saving, compact and controllable.
