Description
Technical field
The present invention relates to waste oil regenerations to utilize technical field, and in particular to a kind of waste oil demulsifier and preparation method thereof and makes
Use method.
Background technique
During waste lubricant oil by hydrogenation purification is pretreated, to first pass through de- mechanical admixture, dehydration and etc. reduce
Subsequent processing difficulty.Free water in waste lubricating oil is easily separated removing, and removes the emulsified water in waste lubricating oil generally then
It needs that demulsifier is first added and is demulsified, so that emulsified water is become free water, then removed again.
Demulsifier is a kind of surface reactive material, it can be such that the liquid structure of emulsifying destroys, water phase and oil in emulsion
Mutually layering is precipitated, and becomes unmixing two-phase.Waste lubricating oil demulsification refers to the chemical action using demulsifier by the oil of emulsifying
Oil and water stratification are precipitated in water mixed liquid, convenient for the dehydration of subsequent waste lubricating oil, to guarantee the water content in waste lubricating oil
It is up to standard.
Ultrasonic wave essence is a kind of mechanical oscillation, has fabulous conductibility in oil, water, in the emulsion of stable structure
When conduction, medium particle can be caused and carry out alternate compression and uphold, and cause the variation of pressure on particle, cause waste lubricating oil
Middle water particle is constantly moved to antinode or node, and under huge acceleration, the aqueous particle in waste lubricating oil generates collision, breaks
" displacement effect " split, coalesced, this structural change coalesce water droplet constantly, finally settle by Gravity Separation.
The factor for influencing ultrasonic dehydration efficiency mainly has (1) ultrasonic frequency, and ultrasonic frequency is lower, decays slower,
The sound field that is demulsified is more uniform；(2) the ultrasonic wave sound intensity, the ultrasonic wave sound intensity is related to propagation medium density, spread speed, frequency etc., sound
It is by force more than a certain range, the water droplet of coalescence can be crashed to pieces, and generate second emulsifying；(3) Ultrasonic Radiation time, ultrasonic time mistake
It is long, energy is not only consumed, will also result in second emulsifying.
Therefore, it is necessary to a kind of waste oil demulsifier, under reaction condition that can be mild, quickly and efficiently by the cream in waste lubricating oil
Change liquid to be demulsified, to remove the moisture in waste lubricating oil.
