Machine centrifugal extraction solvent extraction process of extraction of metal

organic solvent extraction is often referred to as liquid-liquid extraction, refers to a kind of not miscibility with water extraction ability of organic solvents ( Extracting agent) With the extraction of mixed aqueous solution, after fully mixing, because the relative density is different, after clarification and divided into two layers, a layer of organic phase ( Extraction phase) And the other is a kind of water phase ( More than extraction phase) 。 When two phase equilibrium, been extracted substances according to certain concentration. 。 。

machine centrifugal extraction solvent extraction process of extraction of metal

organic solvent extraction is often referred to as liquid-liquid extraction, refers to a kind of not miscibility with water extraction ability of organic solvents ( Extracting agent) With the extraction of mixed aqueous solution, after fully mixing, because the relative density is different, after clarification and divided into two layers, a layer of organic phase ( Extraction phase) And the other is a kind of water phase ( More than extraction phase) 。 When two phase equilibrium was extracted substances according to certain concentration distribution in two phase, so as to achieve the purpose of the separation, purification and enrichment.
this method can separate metal very similar in nature, Such as zirconium and hafnium, tantalum and niobium, nickel and cobalt, rare earth elements, etc. ) Purification, solution to remove the trace impurities.
liquid-liquid extraction equipment with centrifugal extraction machine, box-type extraction tank ( Mixer settler) , extraction tower, of which the most widely used centrifugal extraction machine.
extraction process is mainly have two extraction and reverse extraction operation process, the extraction was made by extraction material returned to the process of water phase; Sometimes for extraction, washing, and the extraction of three operation process, is the back extraction process impurities, washing and extract the most is still in the organic phase extraction, washing and reverse extraction are the liquid-liquid mass transfer process of two phases, its operations include a mixture of two phase and separate. Two phase contact only once, and then remove the extracted liquid and extraction respectively residue is a single-stage extraction, which often short of effective separation, in actual production, often take several. cwl - M type centrifugal extraction machine together, make the organic phase and water phase multiple contact separation effect can be enhanced greatly, the multistage contact is often referred to as cascade extraction.
. cwl - use M type centrifugal extraction solvent extraction extraction metal has the following characteristics:
(1) to adapt to the strong performance - — Compared with the traditional van and extraction tower equipment, under the effect of centrifugal force, the remaining time is short, split phase quickly, to adapt to the wide range of flow ratio, and processing power; By changing the weir plate and frequency control of motor speed can satisfy the different density and viscosity of liquid materials.
2 material stock of small - — Two-phase material stock in the equipment is small, short contact time, more suitable for processing because of long time volatile activity and variability of materials such as antibiotics, etc. , of course, individual system needs two phase together contact time long also can operate separately.
(3) high extraction efficiency - — Phase equilibrium set up fast, easy to implement series single stage or multistage counter-current or wrong washing and extraction, high mass transfer efficiency and grade efficiency approaching 100%, stop not to undermine the established after concentration distribution at different levels, can at any time at all levels of sampling, facilitate testing.
(4) to take up the space is little, — Motor direct drive, no transmission attachments, compact structure, save area and operating space, less auxiliary equipment.
5] adaptable - — Not because of the change of the material influence extraction effect, can deal with small difference in density between the viscosity of the system, and has a strong ability of demulsification.
[6] operating performance is good, — Automatic operation, the operation flow ratio range is very wide. Can continuous uninterrupted operation, also can use small batch more varieties; Can be intermittent operation, can be a single run, also may need many sets of series operation according to the craft, unlimited number, installation, operation and maintenance is simple, you need less workers, can significantly reduce the labor intensity of workers and improve working environment, and a parking is convenient, easy to implement online analysis and automatic control, etc. Power can be run. Without the traditional process of high tower transporting fluid.
once continuous counter-current reliability - — Current implementation is imposed by the mixing chamber of the suction force per level, does not need the other set interstage pump. No force during conventional process equipment capacity, prone to flooding, multistage series connection must be set when the interstage pump.
being supplied equipment easy to enlarge - — Practices prove that small equipment in lab scale and mass production with large equipment effect is exactly the same, unnecessary to consider the amplification effect.
'levies investment costs low - — Small machine product content, extraction solvent, solvent or detergent cost minimum.
⑽ sealed performance is good, — Meet the explosion-proof, and the application of the poisonous and harmful and volatile medium environment and the requirements of GMP.







DE source extraction, recommend the centrifugal extraction solvent extraction extraction metal help you understand the process of extraction equipment and production capacity, technological process, characteristics of the equipment, such as detailed specification, at the same time can also see the relevant customer case and extraction equipment solution, the research trend, you can also browse all extraction equipment.
