| description | PROBLEM TO BE SOLVED: To provide a method for separating and recovering an unused powder fire extinguisher for using the unused powder fire extinguisher as a reusable material by securely and easily separating foreign matter mixed in the unused recovery powder fire extinguisher removed to a container such as a drum can from the unused recovery powder fire extinguisher. SOLUTION: The unused recovery powder fire extinguisher removed from a plurality of extinguishers filled with a prescribed quantity of unused recovery fire extinguisher is transferred to a plurality of containers and delivered to a disposal facility 1, where the unused recovery fire extinguisher is screened through a screen 2A on a first stage of a screen separating device 2, and large foreign matter such as factory waste containing magnetic metals is captured, separated and removed. After that, medium-sized foreign matter is captured in a screen 2B on a second stage and separated and removed. Then, fine foreign matter slightly larger than the particle diameter of the unused recovery powder fire extinguisher is captured in a screen 2C on a final stage, and separated and removed. After the above processes, the unused recovery powder fire extinguisher suitable to be used as a reusable material is recovered. COPYRIGHT: (C)2005,JPO&NCIPI |
