Embodiment
[0020] The process flow of the present invention is as follows: the raw material urea is blown into the reactor by gas ammonia, and the gas ammonia sent from the circulator is preheated to 350-400 ° C, and then the catalyst is blown to fluidize from the bottom of the reactor, and the catalyst is blown into a fluidized state at 385-400 ° C. At 395°C, urea reacts in the reactor to generate melamine. The reactant comes out from the top of the reactor and enters the air guide absorber with the circulating gas to exchange heat with softened water to generate steam. After the catalyst dust is removed by the external filter, it enters the air for preheating The collector further exchanges heat with the cold air to generate hot air at 130-135°C and sends it to the finished product process as one of the heat sources for drying melamine. The reactants enter the collector to cool down and desublimate naturally, and settle the captured melamine to be refined; The circulating gas from the c...
