<p><P>PROBLEM TO BE SOLVED: To provide a method of removing a solidified deposit of a reactive treatment agent disposed in a reaction tube of a decomposition treatment apparatus that decomposes halogen-containing compounds and is so constructed that the solidified deposit of the reactive treatment agent can easily be removed, and a sealing device for sealing the reaction tube of the decomposition treatment apparatus. <P>SOLUTION: The reaction tube sealing device 60 comprises a sealing plate 62 that is detachably attached to the reaction tube 20 of the decomposition treatment apparatus and seals one end of the reaction tube 20, an injection pipe 66 attached to the sealing plate 62 for injecting water into the reaction tube 20, and a discharge pipe 68 attached to the sequestering means (i.e., the sealing plate 62) for discharging the solidified deposit of the reactive treatment agent dissolved in the injected water out of the reaction tube 20 to outside. By filling the reaction tube 20 with water through the injection pipe 66 while sealing the lower end of the reaction tube 20 with the sealing plate 62, calcium chloride, calcium iodide and the like are dissolved into water thanks to their water solubilities and are discharged through the discharge pipe 68 to outside. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
