METHOD FOR REMOVING FLUORESCENT FILM OF FLUORESCENT TUBE AND METHOD FOR RECYCLING WASTE FLUORESCENT TUBE

PROBLEM TO BE SOLVED: To provide a method for removing a fluorescent film, by which the fluorescent film applied on the inner surface of a glass tube of a fluorescent tube can quickly be removed surely. SOLUTION: At least the base part of the fluorescent tube is cut and removed. A gas is introduced into the glass tube 13 of the base part-removed fluorescent tube from one end of the tube 13 to the other end to form a whirling current along the inner surface of the tube 13 so that the fluorescent film applied on the inner surface of the tube 13 can be exfoliated by the whirling current. When the tip of a whirling current generating nozzle 7 is inserted into the tube 13 and the whirling current is formed in the tube 13, the fluorescent film can be removed more efficiently.
