Cyanuric acid production apparatus and preparation method thereof

摘要

The plant is provided with a first rotary reactor (2) where the balls of urea cyanurate are formed and a second reactor (8) where the pyrolysis takes place. The first reactor (2) is provided with an internal helical fin (4) and the second reactor (8) is also rotary. At the exit thereof there is a communication tube (12) placing it in communication with a solids separator vessel (14) which receives an aqueous solution capable of reaching a working level, below which there is the access port (20) of the tube (12) to the vessel (14). The vessel is provided with a lower drain valve (26) and an upper gas exhaust tube (22). IMAGE
