Embodiment 1
[0038] A kind of cyanamide dimerization technique of above-mentioned device adopted in the present embodiment, comprises the following steps:
[0039] S1. Pass fluidization gas at 280°C into the reactor, control the pressure inside the reactor at 0.3MPa, and open the heat exchange device at the same time;
[0040] S2. Adjust the temperature of the heat exchange device according to the temperature and flow rate of the fluidized gas to control the temperature of the fluidized polymerization zone to be 130-200°C;
[0041] S3. After the temperature in the fluidized polymerization zone of the reactor is balanced and stable, cyanamide gas at 500-600°C is introduced;
[0042] S4. The cyanamide gas enters the fluidized polymerization zone, and undergoes a dimerization reaction under the action of a catalyst to generate a mixed gas containing dicyandiamide, and simultaneously uses a heat exchange device to cool down the fluidized polymerization zone;
[0043] S5. Separating the mixed ...
