<p>PURPOSE:To effectively remove offensively odorous components present in the air by providing a packed layer with an alkali metal iodide, an ozonizer, a packed layer with hydrogen iodide, etc., a packed layer with an excess oxidant decomposer, and an air supplier for these layer. CONSTITUTION:The air A to be treated, sucked by a blower 1, is brought into contact with a packed layer 5 with an alkali or alkaline earth metal iodide in a desulfurizing tower 4, where most of hydrogen sulfide, methylmercaptan, etc. are removed. Then, the treated gas is mixed with ozonized air through a diffuser 8 and then introduced knto a deodorizing tower 9, where the gas is brought into contact with a packed layer with hydrogen bromide or hydrobromic acid and offensively odorous components present are remove by oxidaton. Then, the treated air is contacted with an activated carbon-packed layer 3, where residual ozone and Br2 are adsorbed and clean air B is released to the outside.</p> |
