PURPOSE:To clean the environment, by detachably interposing a cloth or a porous board sticking fine particles including metallic ions between porous plates used for a sound-insulation wall and absorbing, decomposing, and sterilizing poisonous gasses permeating the porous plate. CONSTITUTION:A cleaning body 2 made of porous boards or cloths sticking fine particles including metallic ions on the surface are detachably interposed between porous plates used for sound insulation and fire protection. Poisonous gasses like CO, NO, SO passing through the porous board 1 are absorbed and decomposed by the catalytic action of the metallic ions and sterilized by microorganisms. In this way, the environment is cleaned and it can be useful for health improvement of the neighboring people. |
