Description
Technical field
The present invention relates to a kind of dual channel taper extraction element and the method for percolation extraction, for liquid under the conditions of no downspout
The counter-current extraction process of liquid two-phase is different from conventional fillers extraction specifically for chemical separating field and sieve plate extraction provides a kind of tool
There is the extracting process of larger operating flexibility and high stability.
Background technology
Customary filler tower and sieve-plate tower complete liquid-liquid diphase counter-current extraction process in Chemical Manufacture.Packed tower is generally using tool
There is the special metal ring filler of dissection, dispersed phase can be made to be effectively split into small liquid pearl and realize larger two-phase contact surface.
But due to the effective cohesion for lacking dispersed phase, the concentration distribution of dispersed phase is changed greatly with tower diameter, and continuous phase axial backmixing journey
Degree is also higher thus larger to the Enlargement Design difficulty of big tower, limits its application in large-scale separation process.
Sieve-plate tower can make dispersed phase alternately disperse and agglomerate in tower, and the flowing of continuous phase is limited in adjacent two
Between block column plate, be conducive to overcome disperse phase concentration uneven and reduce the axial backmixing of continuous phase.But in order to reach higher extraction
Efficiency is taken to need retaining hole flow velocity degree in a rational range, if flow has large change that can lead to coacervate not in operation
Stablize, thus sieve-plate tower is harsher to design requirement and operating flexibility is not high.
The key for improving extraction efficiency is to develop the separation list that dispersed phase can be allowed effectively to disperse but also make its rapid aggregation
Member, the previous important research direction of mesh are to use sieve plate and filler combination.Application number CN201120556539.7 is disclosed
A kind of combined type perforated-plate extraction tower, setting pressure separating layer, enhances the fast rapid hardening of dispersed phase between column plate between adjacent two sieve plate
It is poly-, improve whole tower extraction efficiency.Application number CN201320842434.7 discloses a kind of extraction dress of corrugated plating compounded mix
It puts, employs the corrugated plating equipped with poroid channel, place rack filler between plate and dispersed phase is cut repeatedly, have by strengthening
Effect disperses to improve mass-transfer efficiency.
Present invention employs a kind of dual channel taper extraction elements, and respective runner is specially devised for liquid-liquid diphase.Point
It is flowed in taper cover plate and the conical baffled annular space surrounded when dephasing flows through extraction element, the distribution hole across cover plate is disperseed
With entering upper level column plate after the continuous phase contact mass transfer outside extraction element；Continuous phase is only conical baffled between conical baffle
It is flowed in the annular space surrounded, the inside that extraction element is flowed into outside extraction element enters next stage column plate.
A kind of dual channel taper extraction element of the present invention improves dispersed phase and the flow pattern of continuous phase.Dispersed phase passes through
Distribution hole on the conical surface is disperseed, and not only increases the surface for dispersion, while can make the dispersion of adjacent extraction element again
It mutually mutually hits, peptizaiton can be strengthened.Secondly, the cohesion of dispersed phase is concentrated in the cone of extraction element and is carried out, and is gradually contracted
Small flow channel can also promote it quickly to agglomerate.The flowing of continuous phase only need to can enter next stage also cross extraction element
Column plate flows uneven phenomenon caused by avoiding the continuous phase flowing over long distances of common sieve-plate tower, is also beneficial to improve average biography
Matter motive force.In addition, using the extraction element of the structure, it need to be only closely packed on entire column plate, not need to specially set
Downspout or stalk are counted, be also beneficial to raising column plate efficiently uses area.The detailed construction of the present invention will be in invention content
With narration in detail again in specific embodiment.
