The air lift externally circulation bubble tower oxidation apparatus includes cylinder bubble tower with top expanded section, outer circulating pipe, gas distributor, reflux liquid distributor and condensator. The outer circulating pipe has its upper end and lower end communicated with the upper part and the lower part of the bubble tower reaction section separately and is used to lead slurry from the upper part of the tower to the lower part via air lift effect so as to form the fluid circulation in the whole tower and complete the liquid phase catalytic oxidation of xylene. The bubble tower has relatively high height/diameter ratio and thus reinforced gas-liquid mass transfer and the air lift outer circulation pipe improves the temperature distribution and concentraion distribution inside the tower. The tower has no moving part, simple structure and low cost and is suitable for oxidizing xylene to prepare terephthalic acid via different technological processes.
