A fully sealed high-transparency glass extraction device and extraction method thereof

Abstract

The invention relates to a liquid-liquid two-phase continuous extraction device in the extraction fields of metallurgy, chemical industry, medicine, etc., especially a fully sealed high-transparency glass extraction device with good oil-water separation effect. The device includes a monomer vertical mixing chamber, Monomer mixing and stirring device, monomer horizontal clarification chamber and mixed phase overflow pipe. The beneficial effect of the invention is that the special glass is integrally manufactured, has good corrosion resistance, high visibility, simple internal structure, good production controllability, and is convenient for operators to control the clarification and phase separation. The design of the tail gas breathing valve enables the extraction device to realize the fully sealed extraction production operation under normal pressure, effectively avoiding the unorganized discharge of the organic phase, optimizing the extraction operation environment, and eliminating hidden dangers in production safety. The design of the oil-water phase liquid level adjustment rod can make the organic phase retention in the clarification chamber meet the best requirements and reduce operating costs.

Description

technical field [0001] The invention relates to a liquid-liquid two-phase continuous extraction device in the extraction fields of metallurgy, chemical industry, medicine, etc., especially a fully sealed high-transparency glass extraction device with good oil-water separation effect. [0002] technical background [0003] Liquid-liquid extraction is an effective method for separating and enriching useful substances from a solution. It uses the different distribution of solutes between two immiscible liquid phases to achieve the purpose of separation and enrichment. Because liquid-liquid extraction has the advantages of fast equilibrium speed, good separation effect, large processing capacity, high metal recovery rate and easy operation to realize automatic control, liquid-liquid extraction is more and more widely used in metallurgy and chemical industry and other application fields. Now in the periodic table of elements Almost all elements can be separated and purified using ...

AI Technical Summary

Problems solved by technology

However, the box-type mixing and clarifying extraction tank also has deficiencies, such as the poor sealing of the box-type extraction tank, the unorganized discharge of organic reagents, certain safety hazards, and poor production control, failing to accurately control the phase separation and self-adjustment outflow rate of phase

In addition, due to the high viscosity of the mixed phase, it is easy to form an emulsified system, resulting in difficulty in phase separation and long time for clarification and separation. However, the settling space of the clarification chamber is limited and the height of the overflow port is fixed, so the mixed phase will stagnate in the clarification chamber and separate. The phase is not complete, resulting in problems such as phase entrainment loss
