The present invention relates to a device and method for continuous recovery of ammonia nitrogen from aluminum ash. The device comprises a reaction kettle, a steam generator, and a feeder. The steam generator and the feeder are both mounted on the reaction kettle. The steam generator delivers steam into the reaction kettle, and the feeder is used to deliver aluminum ash into the reaction kettle.
