AI Technical Summary
Existing molten salt sodium nitrate granulation processes and systems generally face clogging problems, which affect production continuity, reduce product quality, and increase costs.
The system employs a combination design of an internally hollow granulation tower, a spraying mechanism, a wall scraping mechanism, and a discharge mechanism. It combines the dual motion of revolution and rotation to spray liquid sodium nitrate, and the wall scraping mechanism removes the adhering liquid sodium nitrate. The discharge mechanism prevents clogging, and dry nitrogen or argon gas is used to prevent nozzle blockage.
It significantly improves the uniformity of granulation particle size, prevents nozzle clogging, ensures production continuity, reduces the risk of clogging at the discharge end, and lowers energy consumption and costs.
