<p>PURPOSE:To obtain the compact device for blocking the infiltration of the blast and dust, blocking the infiltration of microorganisms and blocking chemical odor by absorption by laminating a hemp palm bed, a chemical-coated membrane and an absorbent bed in a vessel. CONSTITUTION:Hemp palm beds 6 and 8 obtained by laminating one or plural sheets of hemp palm bark, chemical-coated membranes 7, 9 and 11 obtained by impregnating an air-passable sheet with triethylenediamine or sodium hypochlorite and air-passable deodorant beds 10 and 12 are laminated in a vessel 1. When the air to be treated in passed through the vessel, dust is absorbed in the hemp palm beds 6 and 8, the microorganisms such as virus are absorbed and sterilized and nitrogen oxides and carbon oxides are cut by absorption in the membranes 7, 9 and 11, and the chemical odor and putrid smell are absorbed and the nitrogen oxides and carbon oxides are cut by absorption in the deodorant beds 10 and 12.</p> |
