Document Type and Number:
Japanese Patent JP5120475
Kind Code:
B2
Abstract:
A manufacturing facility for quicklime is provided, which can manufacture highly active quicklime by a simple manufacturing facility, and which can also separate and recover, in a high concentration, CO 2 gas generated at the time of manufacturing quicklime. The manufacturing facility for quicklime is configured by including: a regenerative calciner 11 which has a supply port 11a for supplying granular limestone C into the regenerative calciner 11, heating means capable of maintaining the temperature of the atmosphere in the regenerative calciner 11 at a temperature not less than the calcination temperature of the limestone, an exhaust pipe 15 connected to an upper part of the regenerative calciner 11 so as to discharge combustion exhaust gas of the heating means and CO 2 gas generated by the calcination of limestone, and a discharge port 14 for taking out quicklime produced by the calcination; and a heat medium 16 which has a particle diameter larger than the particle diameter of the limestone and which is filled in the regenerative calciner 11.
