Abstract

The invention relates to the technical field of multiple distillation extraction for chemical engineering, in particular to a chemical multi-distillation extraction device. The device comprises a rectifying tower for multiple distillation, the lower end of the rectifying tower for multiple distillation is connected with a liquid-phase component rectifying pipe system, the upper end of the rectifying tower for multiple distillation is connected with a gas-phase component rectifying pipe system, the gas-phase component rectifying pipe system is connected with an extraction device, and a mixed liquid feeding pipe system is connected to the middle of the rectifying tower for multiple distillation. According to the device, a rectifying tower for multiple distillation is arranged according to the principle that purification can be achieved through gas-liquid two-phase contact, basic equipment construction of rectifying operation is completed in cooperation with corresponding process equipment, a programmable controller is adopted for forming a feedback system by the temperature of each layer in the tower and each valve outside the tower, and automatic control can be achieved.

Description

technical field [0001] The invention relates to the technical field of multiple distillation extraction for chemical industry, in particular to a multiple distillation extraction device for chemical industry. Background technique [0002] The more appropriate term for multiple distillation extraction in chemical production is rectification, and rectification equipment such as rectification towers is generally used to achieve the purpose of two-phase rectification. [0003] The distillation and extraction devices used in modern chemical industry mostly use tower containers, but how to use tower containers to achieve multiple purifications at the same time of gas-liquid phase is a difficult point. If there is no better solution, the equipment built will not be able to complete the production purpose. Contents of the invention [0004] The purpose of the present invention is to provide a kind of multiple distillation and extraction device for chemical industry, to solve the p...
