Abstract

The invention relates to a bubble-assisted organic liquid film generator. Structures of a gas-phase gas distributing sieve and a gas-phase buffer room are adopted so that a high-speed airflow beam at an outlet of a gas-phase pipeline is rapidly dispersed in the gas-phase buffer room, and thus the stabilizing and the homogenizing of air pressure in gas distributing needles are achieved; a multi-level dispersed flow regulating and pressure stabilizing structure including a light-phase dispersing ring, a light-phase buffer room, a light-phase stream guidance hole, a light-phase stream guidance ring, a light-phase distribution room, a light-phase restrictor ring and the like is adopted, so as to realize the rapid dispersed circulation and the stable-pressure and balance output of light phase; the gas distributing needles are inserted in bubble film generating holes, so as to skillfully combine the light phase and gas phase in the bubble film generating holes, and thus a continuous bubble film is rapidly generated on the surface of a bubble film generating plate synchronously and stably in multiple holes.

Description

Technical field [0001] The invention belongs to the technical field of chemical separation, and particularly relates to a bubble-assisted organic liquid film generator. Background technique [0002] Solvent extraction is a relatively traditional industrial separation and extraction technology. It has the advantages of high selectivity, good separation effect, easy operation and strong applicability. Therefore, it is widely used in petroleum, chemical, pharmaceutical, metallurgy, environmental protection, biological engineering and New material preparation and other fields. With the continuous development of modern industry, the separation system is becoming more and more complex, the concentration of the components to be separated is lower and lower, the nature of the separation object is getting closer, and the environmental governance standards are becoming more and more stringent. Put forward higher requirements. [0003] The gas-assisted solvent extraction technology uses the...
