Abstract: An efficient ammonia desulphurization and oxidation apparatus includes a desulphurization tower, where spray layers in multiple stages and a tower reactor are sequentially arranged in the desulphurization tower; a first gas-liquid distribution plate, a second gas-liquid distribution plate, and a third gas-liquid distribution plate are sequentially arranged in the tower reactor; an ammonia distribution zone is formed between the first and second gas-liquid distribution plates, and an ammonia water distributor is further arranged between the first gas-liquid distribution plate and the second gas-liquid distribution plate in the ammonia distribution zone; an absorption zone is formed between the second and third gas-liquid distribution plates; an oxidation zone is formed between the third gas-liquid distribution plate and a bottom of the tower; in the oxidation zone, oxidizing air distributors in multiple stages are arranged at a lower side of the third gas-liquid plate.
