<p>PROBLEM TO BE SOLVED: To cost effectively and efficiently carry out the treatment of odorous components by providing an odorous component treatment apparatus having electric discharge sections to the gas to be treated which contains the odorous component to a gas flow section of the gas to be treated with a flow velocity regulating mechanism for maintaining the velocity of flow of the gas to be treated passing the electric discharge sections at a range of specific value. SOLUTION: The gas to be treated which contains the odorous components, such as hydrogen sulfide, is introduced from an introducing port 2 into the apparatus and is first distributed evenly to the plurality of electric discharge sections 3 from a distributing duct 1. Electric discharge electrodes are respectively installed in the respective electric discharge sections 3 and electrons are radiated therefrom to activate the hydrogen sulfide and oxygen in the gas to be treated. Next, the gas to be treated is introduced into a vapor phase reaction vessel 8 where the reaction of the oxygen and hydrogen sulfide in an active state is accelerated and both are oxidation cracked to water and sulfur. In succession, the gas to be treated is supplied to a catalytic vessel 6 where a slight amount of ozone generated as a by-product is adsorbed. At this time, the number of revolutions of an induction fan 4 is so regulated that the velocity of flow of the gas to be treated passing the electric discharge sections 3 is maintained in a range of 7 to 30m/s.</p> |
