Abstract

The invention discloses a multi-column series negative pressure rectification device and an application method thereof, comprising: an outer casing of a rectangular structure, in which a plurality of rectification columns are arranged, and adjacent rectification columns pass through a predetermined distance The empty column sections are spaced apart; wherein, the side of the lower end of the rectifying column located in the first section is provided with a steam inlet flange communicating with the evaporation unit; the side of the empty column section located at the end is provided with a steam outlet communicating with the steam evacuation equipment flange; the bottom of the two adjacent rectification columns is provided with an air inlet that matches the steam inlet flange in space, and a matching air outlet is arranged on the top of the opposite side of the air inlet, so that each fine The distillation columns are connected in series in the outer shell of the rectangular structure through empty column sections. The invention provides a multi-column series negative pressure rectification device and an application method thereof, which reduces the manufacturing difficulty of the rectification tower, reduces the equipment cost, and has more obvious cost advantages compared with the rectification tower with a height of more than 50m.

Description

technical field [0001] The invention relates to the technical field of rectification and separation of multi-component liquid mixtures, in particular to a multi-column series negative pressure rectification system. Mainly used in the separation and extraction of super heavy water from natural water (D 2 18 O), also suitable for the separation of multi-component liquid mixing systems. Background technique [0002] Rectification is a distillation method that uses reflux to separate liquid mixtures. It is the most widely used liquid mixture separation operation in the chemical industry, and is widely used in petroleum, chemical, light industry, food, metallurgy and other departments. The traditional rectification equipment is a continuous rectification device, including a rectification column, a reboiler, a condenser, a distributor, and the like. The feed liquid and the liquid returning from the upper column section descend together through the packed layer, and the vapor fr...
