METHOD AND APPARATUS FOR REMOVING FLUORINE FROM FLUORINE-CONTAINING WASTE

摘要

PROBLEM TO BE SOLVED: To provide a method for removing fluorine from fluorine-containing waste which can be performed in a shorter time than heretofore.SOLUTION: The method for removing fluorine includes: an introduction process of introducing fluorine-containing waste into a heating furnace 31 by using the heating furnace 31, a water vapor supplying means and a waste gas treatment unit 4; a reaction process of supplying water vapor or water into the heating furnace 31 and bringing water vapor into contact with the waste at 850 to 1,300°C for 0.5 to 10 h; and a waste gas treating process of treating generated hydrogen fluoride gas with the waste gas treatment unit 4.
