The traditional cyanuric acid hydrolysis production process in China was subverted and innovated. Through adopting a new type of equipment, a new process different from the traditional one, and using the principle of microchemistry， the particle size of raw materials was reduced, and increasing reaction speed. In order to reduce the reactor and disinvestment，raising device purpose of safety factor. Because of miniaturization of equipment, the device is safer, and cleaner. The equipment was operated under normal pressure， the labor intensity was reduced, working environment was improved, operation process was optimized to realize the organic unity of human, machine, material, method and environment. It has a great promotion value for hydrolysis and refining of cyanuric acid.
