A method and a device for synchronous high-speed photographing of microparticle rotation in a liquid cyclone field and for determining the rotation velocity of a microparticle in a liquid cyclone field by using a combination of a synchronous high-speed photographing system and a transparent microparticle containing two centrosymmetrically arranged inner cores having the same diameter. The method comprises: using a transparent microparticle comprising two inner cores having the same diameter and arranged centrosymmetrically as a rotation test particle; acquiring synchronously two groups of two dimensional image series of microparticle motion in a liquid cyclone field using two orthogonally arranged high-speed digital cameras; and reconstructing a three dimensional motion trajectory of the microparticle from the two groups of synchronous image series, and determining a rotation velocity of the microparticle in the cyclone field at the same time.

A process and an apparatus for separating and recovering waste alkali from a cyclohexane oxidation solution are provided. A gradient combination of the gravity separation technique, the vortex separation technique and the coalescence separation technique is used to carry out fine separation of the waste alkali liquor from the cyclohexane oxidation solution. The purified cyclohexane oxidation solution is fed into a down-stream apparatus. Most of the waste alkali liquor thus separated is recycled, while the remaining is expelled. The expelled waste alkali liquor is incinerated in an incinerator, followed by recovering the molten species using a pneumatic pulverization process.
