Lime kiln device adopting circulating hot air

The invention relates to a lime kiln device adopting circulating hot air and a production method for industrial lime. According to the lime kiln device adopting the circulating hot air and the production method for the industrial lime, in the preparation process of the lime, limestone is calcined by using the circulating hot air, the calcined waste circulating hot air is used for preheating limestone ore, and the preheated waste circulating hot air is cooled, is subjected to dust removal, then is conveyed to a regenerative heating furnace set, is heated to a set calcining temperature and thenis sent back to a lime kiln system for calcining. The lime kiln device adopting the circulating hot air and the production method for the industrial lime have the advantages that the limestone is calcined by using the circulating hot air, so that the quality of the lime can be remarkably improved, the yield of the lime can be increased, the productivity can be improved, and high-purity CO2 can beconveniently recycled; and
