Zusammenfassung:	The invention provides an aluminum oxide feeding device for an aluminum electrolysis flue gas cleaning system. The aluminum oxide feeding device comprises a feeding box (12) provided with a feeding opening (10) and a gate valve (14) which is arranged in the feeding box (12) and located below the feeding opening (10). The aluminum oxide feeding device for the aluminum electrolysis flue gas cleaning system further comprises an impeller feeder and a frequency converter. An impeller (161) of the impeller feeder (16) is arranged in the feeding box (12) and located below the gate valve (14). The frequency converter (18) is in signal communication with the impeller feeder (16) so as to adjust the rotation speed of the impeller (161). The aluminum oxide feeding device for the aluminum electrolysis flue gas cleaning system at least can achieve continuous and stable aluminum oxide feeding.
