Centrifugal extraction machine and working principle of the extraction tank
Extraction equipment is early extraction equipment, the extraction tank in the separation of mixed operation is mainly rely on gravity separation, and the new type of centrifugal extraction machine is rely on centrifugal force for hybrid separation, the working principle of the distinction that having essence, the extraction technology of zhengzhou days finishing parsing for everyone.
a, extraction tank
1, the extraction tank to introduce
extraction tank (
Also called mixer settler)
Earlier, is the industrial application and still widely used the mature technology of extraction equipment.
Is one of the two phase separation by gravity to contact extraction equipment, step by step as water phase and organic phase flow � �, separable counterflow and parallel flow;
In terms of energy input mode, can be divided into the air, mechanical stirring and ultrasonic pulse stirring;
Is the box structure, in addition to simple box type mixer, and more compartment, modular a variety of other mixer.
2, the working principle of
extraction tank is one of the two phase separation by gravity to contact step by step extraction equipment, mainly by the mixing chamber and clarification of two parts.
Raw material liquid and extraction agent after their first inlet into the mixing chamber, by mixing blender mixing and mass transfer, and then through the overflow baffle into clear indoor, natural separation was achieved by gravity.
Finally into different export respectively, complete extraction process.
In practical production, general for multi-stage extraction tank in series, and is equipped with reverse extraction, washing, regeneration section section.
2, centrifugal extraction machine
1, centrifugal extraction machine introduction
centrifugal extraction machine is a new, rapid, efficient liquid-liquid extraction separation equipment.
The working principle of centrifugal extraction machine with both the distinction that having essence.
Centrifugal extraction machine is the use of motor driven rotary drum high-speed rotation, the density of different and each of two immiscible liquids in drum or under the action of shear force produced by the rotation of blades complete mixing and mass transfer, and the effects of the centrifugal force in the high-speed rotating drum under rapid separation.
2, the working principle of
(1), mixing and mass transfer process -
Or two phase solution according to certain proportion respectively from two feeding tube into the drum and shell type ring gap formed between the mixed zone, with the aid of the rotation of the drum, through the turbine disc and the impeller the two-phase mixing and dispersing quickly, and two phase solution fully mass transfer.
Complete mixing and mass transfer process.
(2), two phase separation process -
Mixture under the action of vortex disk into the rotary drum, in the plate to form the bulkhead area, mixture quickly with synchronous rotary drum, in under the action of centrifugal force, the heavier than major phase fluid in the process of upward mobility and gradually away from the drum center on the drum wall;
Small proportion of liquid phase gradually away from the drum wall and on to the center, after clarification of two phase fluid end respectively through their weir plate into the collection chamber and the tube was closed to derivation, respectively, to complete two phase separation process.
