The invention belongs to the technical field of reactors and environmental engineering in chemical engineering, and relates to a tubular pressurizing, oxidizing and ammoniating integrated reaction system for flue gas ammonia desulphurization. The system comprises a desulfurization tower, an incomplete oxidation solution tank, an oxidation-ammoniation reaction system and a gas-liquid separation system, the desulfurization tower is connected with the incomplete oxidation solution tank, the incomplete oxidation solution tank is connected with the oxidation-ammoniation reaction system, the oxidation-ammoniation reaction system is connected with the gas-liquid separation system, and the gas-liquid separation system is connected with the desulfurization tower. A tubular reactor technology is adopted to carry out pressurized oxidation and ammoniation on a desulfurization solution, precise oxidation and ammoniation are realized, the reactor is small in size, sensitive to control, capable of achieving rapid oxidation
