The agitating device of sub- concentrated solution secondary dilution process.
Background technique
In industries such as petrochemical industry, food and pharmacy, a kind of Dilute Polymer Solutions are needed to configure.Usual way is by high score
Son first configures a kind of concentrated solution or semidilute, so that small solvent molecule first permeated, be diffused between macromolecular, slackens macromolecular
Between interaction force, complete high molecular swelling process；Then secondary dilution is carried out again and obtains Dilute Polymer Solutions, completes high score
The course of dissolution of son, in this process, the movement of segment and the whole chain of molecule accelerates after swelling, strand loosening, disentanglement, high
It is uniform that molecule and solvent molecule reach directional diffusion.This way can greatly reduce setup time, improve efficiency.
Change procedure of the Polymer Solution solubility from dense to dilute is exactly that molecule Chain System turns from the multichain state being intertwined
Become single-stranded process.The essential distinction of weak solution and concentrated solution is in weak solution that a single molecular chain ball of string is isolated existing,
Between each other without overlapping, and in dense system, aggregation and winding occur between macromolecular chain.
The essence of whipping process is exactly to pass through the rotation of impeller mechanical energy is passed to liquid, to make liquid in equipment
Forced convertion is done in portion, and reaches uniform admixture.What stirring was focused on is the motion mode and severe degree of material in stirred tank,
And this moving situation is for the adaptability of given process.There are three kinds of diffusion ways during being stirred: overall right
Stream diffusion, eddy diffusivity and molecule diffusion.Convention diffusion is to exclude stream and stream is induced to cause a wide range of macroscopic motion of tank liquid,
And fluid flow circuit in entire slot is generated, this mixing is also known as the mixing of large scale.This stage, which needs to rationally design, stirs
