PROBE FOR EXTRACTING EXHAUST GAS, CEMENT CALCINING EQUIPMENT PROVIDED THEREWITH AND EXHAUST GAS TREATING METHOD IN CEMENT CALCINING EQUIPMENT

摘要

PPROBLEM TO BE SOLVED: To provide a probe for extracting exhaust gas by which collection efficiency of chlorine compounds remaining in the exhaust gas extracted from a cement kiln is raised and coating trouble in cement calcining equipment due to chlorine circulation can be prevented and further to provide cement calcining equipment provided therewith and an exhaust gas treating method in the cement calcining equipment. PSOLUTION: The probe for extracting exhaust gas is provided with an inner tube 11 and an outer tube 12. The inner tube 11 is provided with a cylinder part 21 which can move freely along an axis line Ax and a cylinder part 22 which is provided coaxially in the cylinder part 21, is freely slidable toward the cylinder part 21 and can be fixed at an arbitrary position. An internal space formed by the cylinder parts 21, 22 becomes an extracted exhaust gas flow passage 25 and a space part formed between the inner tube 11 and the outer tube 12 becomes a cooling air flow passage 26.
