Rotary micro-channel demulsification method

Abstract

The invention discloses a rotary micro-channel demulsification method. A rotary demulsification part, a supporting part and a numerical control part are included. The rotary demulsification part comprises a demulsification cylinder, a rotary motor and a rotary shaft, the top of the demulsification cylinder is connected to the rotary motor through the rotary shaft, the demulsification cylinder comprises an inner demulsification cylinder and an outer demulsification cylinder, the outer demulsification cylinder is fixedly connected to the rotary motor through a glass plate, the inner demulsification cylinder is fixedly connected to the rotary shaft, the supporting part comprises a supporting base and a supporting rod, and the side face of the supporting rod is fixedly connected to the numerical control part. The method comprises the following steps: S1, preparing an emulsion, S2, adjusting the device, S3, demulsifying by the device and S4, collecting a demulsified liquid. The outer demulsification cylinder rotates, the demulsification part deflects, polytetrafluoroethylene and organic glass materials are adopted, rapid separation is achieved, efficient demulsification is achieved, andan emulsion feeding hole, an upper discharge hole and a lower discharge hole are limited, so that sufficient and stable demulsification is realized. Different demulsification requirements are met byutilizing an embedding mode.

Description

technical field [0001] The invention relates to the field of microchannel demulsification, in particular to a rotary microchannel demulsification method. Background technique [0002] Demulsification means that the emulsion is completely destroyed and becomes two immiscible phases. In actual production, physical and mechanical methods such as electrodeposition, filtration, and ultrasound are used for demulsification, or physical and chemical methods by adding demulsifiers. The physical and mechanical methods are due to It has the advantages of simple operation and no need to add chemical reagents for reaction. It is widely used in crude oil extraction, oily sewage, lubricating oil recovery and rare earth extraction. In recent years, with the rise of microscopic chemistry, the method of demulsification has also been extended. Into micro-chemistry, and the requirement for the purity of the emulsion phase is getting higher and higher, such as the journal "Chen Feng, Yang Zong, ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned microchannels are demulsified by standing or rotating. However, when the emulsion particles with a Sauter average diameter of 10 μm are demulsified, the demulsification efficiency drops significantly or even cannot be separated. At the same time, for the same volume The demulsification of the same sample is demulsified, and the time of complete demulsification is also very different, which will undoubtedly increase the time cost of demulsification; at the same time, under the condition that the average diameter of Sauter is 7 μm, the efficiency of demulsification is extremely unstable, and it takes a long time More than ten cycles of demulsification
