The present application relates to the field of petrochemical industry and environmental protection technology, and particularly relates to a multi-core pipe parallel type main and auxiliary cavity cyclone oil-gas-water separation system and a separation method. The method comprises obtaining the time of flight of reflected sound waves and the Doppler power spectral density diagram of the cyclone separation main cavity; determining the axial coordinate sequence and the radial coordinate sequence based on the time of flight; determining whether the cyclone intensity of the cyclone separation main cavity is qualified based on the height difference of the cyclone liquid column; in response to the unqualified cyclone intensity, determining the adjustment direction of the gas phase outlet back pressure based on the cyclone gas core ratio; based on the qualified cyclone intensity, determining whether the cyclone load of the cyclone separation auxiliary cavity is up to standard based on the frequency spectrum width value, and in response to the unqualified cyclone load, prolonging the liquid phase separation time of the cyclone separation main cavity; based on the qualified cyclone load, determining whether there is a downward trend of the oil-gas-water separation efficiency, and enabling sound early warning when the oil-gas-water separation efficiency has a downward trend. The present application solves the problem of lag in sensing the state fluctuation of the oil-gas-water mixed liquid flow field.

The application relates to the technical field of aeration devices, in particular to a micro-nano active ceramic aeration device which comprises a shell and a self-cleaning mechanism, the inside of the shell is fixedly connected with two mounting plates; the hexagonal active ceramic sheet and the self-cleaning mechanism are arranged, high-speed cyclone makes the gas receive stronger shearing force when passing through the micropores of the ceramic sheet, the micropore structure of the ceramic sheet is matched, the gas can be more efficiently broken into micro-nano bubbles with more uniform diameters, the gas-liquid mass transfer area and the dissolved oxygen efficiency are improved, meanwhile, part of the gas can drive the backforce blade, the brush shaft is rotated on the connecting seat under the drive of the backforce blade, a plurality of mounting seats and rotary brushes are driven to rotate, the plurality of rotary brushes continuously or periodically clean the surface and pores of the hexagonal active ceramic sheet along with the airflow, the adhered pollutants can be timely removed, the aeration efficiency caused by the pore blockage is avoided, the micropores of the ceramic sheet can keep unblocked for a long time, and the stable micro-nano bubble generation effect can be maintained.
