Beschreibung
Zusammenfassung:The invention discloses an intensive fluorination reactor for producing dry-process aluminum fluoride. The intensive fluorination reactor comprises a first-section fluorination reactor and a second-section fluorination reactor connected with the first-section fluorination reactor, an aluminum hydroxide overhead bunker is connected with the inlet of the first-section fluorination reactor through afirst nitrogen sealing chamber, a screw feeder and a sealing chamber in sequence; and the first-section fluorination reactor is connected with the second-section fluorination reactor through a fluidization reverse conveying pipe. The ammonium fluoride overhead bunker is connected with the second-section fluorination reactor through a second nitrogen sealing chamber and an ammonium fluoride spiralfeeding pyrolyzer, and the discharge port of the second-section fluorination reactor is connected with a nitrogen sealing unloader. The intensive fluorination reactor is a novel fluorination reactor which is developed for over
