Acetochlor extraction extraction:
Acetochlor is a kind of amide herbicides, and have good herbicidal effect, It is mainly used to weeding on crop such as soybean, potato, sugarcane, peanut, corn and cotton. for the acetochlor reaction liquid post processing, it need acid cleaning, alkaline cleaning and washing to reach qualified technical index.
Aiming at the disadvantages of traditional centrifugal extractor, Zhengzhou Tianyi Extraction Technology Co.,Ltd. bring out CWL-M series centrifugal extractor, and own independent intellectual property rights , patent number :ZL2014205865573. Under the same handling capacity condition, this machine power consumption is only 10%~30% of traditional anular type, at the same time, short duration of this machine, split phase quickly, high extraction rate, save cost and solvent could be recycled and reused.
Process description:
The process not limited to acid cleaning, alkaline cleaning and washing, it will be changed according to actual situation.
The process is applicable to separate organic which not insoluble to water.
The process separated by centrifugal force which have more higher separation efficiency
The process cover small areas, take lower power consumption, and can produce continuously.

Customization or not: Yes
If supply small test or pilot-plant test: Yes
Extractor working principle:
1.Mixing and mass transfer process:
Light and heavy liquor enter in the annulus mixed zone proportionally and from two different feed pipe orifice respectively, which formed by bowl and shell, with the help of bowl’s rotation, the two phases through turbine disc and impeller mixing and dispersing quickly, after mass transfer completely, to finish mass transfer process.
2. Two phases separation process
With the eddy-current disc help, mixture enter in bowl, at the compartment formed by board, the mixture is quickly synchronized with the bowl, under the action of centrifugal force, the larger density liquor moving away from the bowl center to the wall gradually in the upward flow; and the small density liquor doing the opposite, after clarification, two liquids enter into collection chamber with their own weir plate respectively, and drawn out by tigella, to finish the separation process.
Extractor advantages:
  Separation effect is obvious and large handling capacity;

●  Two phase materials contact with short time, and save extraction agent consumption and save cost;

●  High mass transfer rate, high stage efficiency, convenient start and stop, it can not break balance when stopped.

●  Cover small area, the cost of comprehensive investment is low.

●  Well-adapted, good flexibility, with intermittent operation, or single operation, or continuous counter current operation, and there is no need to add interstage pump.
