Solvent extraction to extract 10-channel DMAC wastewater treatment equipment selection

by:Deyuan      2020-09-03
Some chemical companies or new material company in the process of production and processing will produce large amounts of 10-channel DMAC wastewater, such waste water inside the high concentration of organic matter, without treatment is emissions, can cause great harm to the environment, at the same time, the organic matter is not inside the extracted, also is a waste of resources.

to extract 10-channel DMAC wastewater treatment, the common way is solvent extraction, the principle is to use suitable extractant, waste water and extracting agent injected into the extraction device, through mixing, moved to the extraction agent, organic matter and two phase separation, the organic matter. Solvent extraction technique has the advantage of operation is simple, high extraction efficiency, extraction solvent was cheap at the same time, the late can be recycled.

in the near future a new material company, have plenty of 10-channel DMAC wastewater produced in the production process, the need for recycling. According to the customer's specific system and process, our company recommends CWL250 - to the customer M type new centrifugal extraction machine, specializing in the extraction wastewater, organic matter in effect is remarkable.

centrifugal extraction machine is more widely used liquid-liquid extraction separation equipment, compared with other traditional extraction equipment, the working principle of centrifugal extraction machine the distinction that having essence. Centrifugal extraction machine mainly rely on centrifugal force for rapid mixing and separation, mixing and mass transfer speed, high extraction efficiency, simple and convenient operation, and large quantity of low power consumption, are widely used in many fields of extraction separation unit operation.

extract 10-channel DMAC wastewater recycling concrete operation process:

10-channel DMAC wastewater with extraction solvent 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 to make two phase mixing and dispersing quickly, two phase solution fully mass transfer. Complete mixing and mass transfer process.

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.
