The invention relates to a magnetic driving rotary gas distributor equipment of gas-liquid multi-phase system. It includes a tower device with magnetic driving device, the rotary-type gas distributor can be directly rotated in the tower bottom to make gas distribution. The gas distributor is driven by rotary permanent magnetic field produced by magnetic driving device and rotated so as to implement goal of rotary gas distribution. In the supporting disk of the gas distributor a gas ingress pipe hole is set, and the ring-shaped gas distribution cavity chamber in the supporting disk and the gas-feeding circular hole on the rotary hollow shaft can be used for making gas distribution, in the bottom end of the rotary hollow shaft a cleaning pollution-discharging valve is mounted.
