Example Embodiment
[0020] The production process of the present invention includes the following steps:
[0021] ① After mixing cyanuric acid, calcium carbonate and water in proportion, put them in the batching kettle and stir to form a slurry. The weight ratio of cyanuric acid to calcium carbonate is 1:0.7-0.8, and water is 7-16 times the weight of cyanuric acid. Any value within the stated value range is acceptable;
[0022] ②Push the slurry into the pre-chlorination reactor for pre-chlorination reaction;
[0023] ③After the pre-chlorination reaction, the slurry enters the differential circulator for chlorination reaction. At the same time, chlorine gas is introduced from the bottom of the differential circulator, and the reaction temperature is 10℃-30℃;
[0024] ④ The residual chlorine generated in the chlorination reaction is sent back to the pre-chlorination reactor for reuse;
[0025] ⑤Use a centrifuge for liquid-solid separation of materials after chlorination reaction;
[0026] ⑥ The liquid ...
