PURPOSE:To improve the long range durability of deodorizing capacity by constituting a deodorizer by providing the adsorbent for odor components, the oxidizing catalyst to oxidize and decompose odor components by heating, and the heating means to heat the adsorbent and the oxidizing catalyst at a specified temp. CONSTITUTION:The oxidizing catalyst 21 is provided in such a way that it sandwiches the adsorbent 22, and the electric heating wire of a heater 23 is provided as the heating means to constitute a deodorizing device 2. In this device, the adsorbent 22 is heated after the oxidizing catalyst 21 is heated to be activated so that the desorption of odor components from the adsorbent 22 is always carried out after the oxidizing catalyst 21 is activated. By this method, the odor components are decomposed to be deodorized without omission. When the odor gas is gaseous acetaldehyde, alumina honeycombs supporting cobalt oxide are used for the oxidizing catalyst 21. For the adsorbent 22, the activated carbon, etc., formed in honeycomb shape is used. |
