Extract of valuable metals from waste liquid can not only resources recycling, at the same time also can protect the environment. Some chemical plants or ore mining companies currently in the process of production and processing will produce large amounts of waste liquid, waste liquid containing a lot of metal elements, if not handled, can cause environmental pollution, and waste of resources. In view of the liquid waste processing, generally using the solvent extraction method, metal elements in the waste liquid to extract, this would require the use of centrifugal extraction machine.

centrifugal extraction machine in the water phase extraction is widely used in organic phase operation, and the extraction effect is good, low comprehensive cost. Below to extract metal chromium waste as an example, the experiment shows that the centrifugal extraction machine in waste liquid extraction effect of metallic elements.

lianyungang a environmental protection company, has yearly produces 150000 tons of waste liquid are in urgent need of processing, mainly containing chromium waste liquor of elements, to extract the recycling. Our company according to the situation, choose CWL50 - M experimental centrifugal extraction machine experiments.

the first material liquid analysis, according to the material liquid is to choose the appropriate extraction agent, in the replace with a extractant, choose good after extraction agent, needs to be two match ratio, good operation conditions were determined, after began experimenting.

will waste liquor and extraction agent according to certain proportion respectively from different entrance into centrifugal extraction machine, 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 again after the effect of drum centrifugal force through two separate out of the body side by side.

by the experimental results show that after centrifugal extraction machine operation, the chromium in waste liquid withdrawal rate over 95%, the effect significantly, the experiment result indicates the industrialized production line can also be good to to the corresponding extraction effect.

centrifugal extraction machine is widely applied in many fields of extraction section, because it works with the traditional extraction equipment, 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.

if you want to know the detailed operation process of centrifugal extraction machine and process, can contact extraction technology co. , LTD. Zhengzhou days!
