Description
Technical field
The utility model relates to separation equipment technical field, specifically a kind of packed extraction tower redistributor.
Background technology
Liquid-liquid extraction is one of important method of chemical separating, is the separation or the purification that utilize the difference of the distribution ratio between the solvent of solute or partial miscibility immiscible at two kinds to realize each component.Packed extraction tower is one of capital equipment realizing Liquid-liquid Extraction Processes, and its main advantage is to realize large-scale continuous production.In packed extraction tower, mainly rely on density contrast, under gravity, decentralized photo, with the form of droplet cluster and continuous phase counter current contacting, carries out mass transfer.
For packed extraction tower, the effect of filler mainly contains two aspects, and one is the axial backmixing suppressing continuous phase and decentralized photo, and two are to provide surface area to promote the pulverizing of decentralized photo, polymerization and to disperse to strengthen mass transfer again.But,, continuous phase ratio of viscosities smaller at two-phase density contrast is larger, axial backmixing in packed extraction tower is very serious, especially the axial backmixing of continuous phase, and along with chemical industry unit scale maximize development, the enlarge-effect of packed extraction tower is particularly evident, and its tower height of about 90% is for making up axial backmixing, this not only constrains extraction output of column, and has a strong impact on the separative efficiency of extraction tower.
Chinese patent 201210177128.6 discloses a kind of packed extraction tower with redistributor and/or vertical baffle, circular downeomer offered by the redistributor wherein arranged, continuous phase enters lower floor's filler by downspout, and decentralized photo then enters upper strata filler by the circular hole on metal dish.But this structure, eddy current can be formed at downspout top, the drop disperseed is made again to bring in downspout and enter lower floor's filler, and lower floor's filler dispersed phase drop from bottom to top can not be redistributed by circular hole in disk bottom polymerization completely again, part directly will enter upper strata filler by downspout, forms short circuit.These two kinds of bad flow regimes will directly cause the axial backmixing of continuous phase and decentralized photo, have impact on the raising of mass-transfer efficiency.
