Abstract: A process and device for producing specialty melamine using a gas-phase quenching method. The production process comprises: a hot process gas from an outlet of a melamine reactor is in contact with a cold process gas in a crystallizer (6), a generated solid A is discharged from the bottom of the crystallizer (6), and a mixed gas enters a collector (7) for gas-solid separation to obtain a solid B; the solid A is conveyed to a high-pressure collecting device A (63) using a high-pressure conveying gas A, wherein the high-pressure conveying gas A is maintained at 120°C or above during conveying, and upon gas-solid separation in the high-pressure collecting device A (63), the solid A is conveyed to a packaging device A (65) using a low-pressure conveying gas A, wherein it is ensured that the solid A at a conveying end does not exceed 85°C.
