Abstract
The utility model relates to a combustion-supporting air distribution device for a Maerz lime kiln, and belongs to the technical field of lime kiln production equipment in the metallurgical industry. According to the technical scheme, the device comprises an upper circular ring (2), a lower circular ring (3), a nozzle (4), an inner sleeve (5), an outer sleeve (6), an annular air duct (8) and an air inlet pipeline (9), the two ends of the inner sleeve (5) and the two ends of the outer sleeve (6) are connected with the upper circular ring (2) and the lower circular ring (3) respectively, the annular air duct (8) is formed among the upper circular ring (2), the lower circular ring (3), the inner sleeve (5) and the outer sleeve (6), and the air inlet pipeline (9) is connected with the annular air duct (8). And a plurality of nozzles (4) communicated with the annular air duct (8) are arranged in the circumferential direction of the lower circular ring (3). The combustion-supporting air distribution device has the advantages that the problem that combustion-supporting air is not evenly distributed in the kiln chamber can be solved, and the purpose that the combustion-supporting air is evenly distributed and reasonably calcined is achieved.
