NMP solvent extraction separation with centrifugal extraction machine operation process
solvent extraction method is to use extraction agent to transfer the NMP in water phase extraction. Solvent extraction has the advantage of extractant cheap, convenience of purchase, simple and convenient operation, good separation effect, no entrainment.
in customer can choose centrifugal separation solvent NMP extraction machine, centrifugal extraction machine is rely on the centrifugal force will be mixed two-phase liquid separation, mixing and mass transfer speed, high extraction efficiency, no entrainment. CWL - M series centrifugal extraction model number is more, the customer can choose according to the specific processing.
NMP concrete operation process of separation:
to choose the appropriate extraction solvent extraction agent and water, NMP mixture according to certain compared through different inlet into the centrifugal extraction machine, between the drum and the shell type ring gap formed by the mixing zone, with the aid of the rotation of the drum, through the turbine disc and the impeller to make two phase mixing and dispersing quickly, two phase solution fully mass transfer, mixing and mass transfer 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.
centrifugal extraction machine for NMP extraction performance advantages:
1, centrifugal extraction machine extraction separation efficiency is high, no entrainment phenomenon, meet the customer's requirements;
2, centrifugal extraction machine equipment, simple and convenient operation, convenient maintenance;
3, centrifugal extraction machine capacity is bigger, lower power consumption, reduce the comprehensive cost;
4, equipment using perfluorinated polymer materials, resistant to strong acid corrosion.
