Step uses degradation agent and processing method in embodiment 3, magnetic flow liquid is carried out preliminary treatment, detects main discrete particles after process
97% is reached with the separation degree of carrier fluid；
2. the magnetic flow liquid 1. processed through step is added in inner drum 2, cover inner barrelhead 9 and outer bung 10, and to suction
Coil electricity in attached pipe 3, the magnetic field intensity of control coil is 2.7T；And in whole processing procedure, magnetic field intensity is all the time
Keep constant；
3. motor 8 works, and drives inner drum 2 to rotate, and the rotating speed controlling inner drum 2 is 1000r/min, keep 10min；
In the process, the magnetic-particle in main discrete particles moves to adsorption tube 3 under the action of a magnetic field and adsorbs at adsorption tube 3 table
Face, few part namagnetic substance is filtered by drainage screen 4 to be stayed in inner drum 2, and carrier fluid passes through inner drum 2 sidewall through drainage screen 4
On filtering holes 201 enter in exterior bowl 1；
4. through step 3. after, the rotating speed controlling inner drum 2 reduces to 10r/min, keeps 2.5min；
5. repeat step 3. with step 4. 4 times；
6. motor 8 quits work, coil blackout, reclaims separate substance from inner drum (2)；Open recovery stop valve 7, from
Liquid after recycling in exterior bowl 1, completes the recycling of magnetic flow liquid.
The magnetisable material and the liquid that obtain above-mentioned steps the most afterwards detect, and the response rate of magnetisable material reaches
94.2%.In the present embodiment, the rotating diameter D of inner drum 2 meets:
Example of the present invention is only to be described the preferred embodiment of the present invention, not to present inventive concept and
Scope is defined, on the premise of without departing from design philosophy of the present invention, and this area engineers and technicians technology to the present invention
