| titleOfInvention | Ammonia desulphurization and oxidation apparatus and method |
| abstract | A high-efficiency ammonia desulphurization and oxidation apparatus comprises: multiple spray layers (5) and a bottom sump sequentially provided in a desulphurization column (1); a first gas-liquid distribution plate (11), a second gas-liquid distribution plate (12), and a third gas-liquid distribution plate (13) sequentially provided in the bottom sump; an ammonia distribution area formed between the first and second gas-liquid distribution plates; an aqueous ammonia distributor (2) is provided between the first gas-liquid distribution plate (11) and the second gas-liquid distribution plate (12) in the ammonia distribution area; an absorption area is formed between the second and third gas-liquid distribution plates; an oxidation area is formed between the third gas-liquid distribution plate (13) and the bottom of the column; several oxidation air distributors (4) are provided at the lower side of the third gas-liquid plate (13) in the oxidation area, a gas-liquid plate is correspondingly provided on each oxidation air distributor; a fluid stirrer (3) is provided above the oxidation air distributors (4). The apparatus is divided in a non-mechanical manner, dividing the desulphurization bottom sump into an ammonia distribution area, an absorption area, and an oxidation area, increasing both the absorption efficiency and the oxidation efficiency. Also disclosed is a desulphurization and oxidation method, in which the pH values of the areas are controlled to be different, so as to optimize absorption and oxidation at the same time. |
