Embodiment 1
[0024] Put 1500L tap water and 150kg hydrazine hydrate (content ≥ 80%) into a 3000L glass-lined reactor equipped with a PH meter online monitoring device, add 40% dilute sulfuric acid dropwise until the pH value is 5-6, and add 1kg sodium dihydrogen phosphate Stabilizer, put in lime nitrogen three times (the total amount of lime nitrogen is 360kg, the effective N content is ≥ 22%, and the lime nitrogen is 120kg each time), stir vigorously, use a flow meter to continuously drop dilute sulfuric acid at a constant speed, and the dropwise addition process , use circulating water to control the temperature at about 45°C, and add dropwise until the pH of the reaction solution is 7.2 to 7.8. After the dropwise addition, the temperature was raised, and the temperature was kept at 70° C. for 3 hours, and the pH of the reaction solution was kept at 7.2 to 7.8 during the heat preservation process. Infuse compressed air into the insulated reaction solution for 10 minutes, then filter the ...
