Abstract

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.

Description

technical field

[0001] The invention relates to a magnetically driven rotating gas distribution device for multiphase systems such as gas-liquid, in particular to a magnetically driven rotating gas used in gas-liquid two-phase flow or gas-liquid-solid three-phase flow distribution device. Background technique

[0002] Gas-liquid two-phase flow or gas-liquid-solid three-phase flow is widely used in the chemical industry, and plays a very important role in various chemical unit operations, such as in the design and operation of gas-liquid and gas-liquid-solid reactors. In operation, the effect of the gas distribution device directly affects the hydrodynamic characteristics of the reactor, such as the size of the bubbles, the amount and distribution of the gas holdup, and the mixing degree of the liquid and gas phases, etc., which in turn affects the reaction yield and selectivity. In the field of biochemical industry, especially food and bio-fermentation industries, gas-liqui...
