[0002] In the existing ammoniation reactors for phosphoric acid or ammonium phosphate slurry in the field of ammonium phosphate production, there are two types: normal pressure and pressurized ammoniation reactors. Normal pressure ammoniation reactors mostly use a stirring tank with a stirring paddle inside, and the liquid flow is a "mixed flow" so that the reactants can be fully mixed. However, the inner wall of the existing ammoniation reactor is prone to scaling during operation, and this scaling is generally removed manually, which is a cumbersome cleaning process.
