EQUIPMENT AND METHOD FOR REMOVING OFFENSIVE ODOR

摘要

PURPOSE:To directly decompose the components of offensive odor by arranging a pair of electrodes to both sides of a conductive electrolyte and introducing the air contg. the components of offensive odor into a gas chamber provided with at least one electrode and impressing voltage between these electrodes. CONSTITUTION:A pair of electrodes 3 are arranged to both sides of a hydrogen ion or oxygen ion conductive solid electrolyte 2. The air A1 contg. offensive odor is introduced into a gas chamber provided with at least one electrode 3. Then voltage is impressed between the electrodes 3 and the components of offensive odor introduced into the gas chamber are directly decomposed by electric energy supplied from the electrodes 3. In this case, a means is interposed in an air introducing route by which the concn. of the component of offensive odor is enhanced with both an adsorption means consisting of activated carbon and a desorption means. Further activated carbon is incorporated into the electrodes 3 as an adsorbent. Furthermore the electrodes 3 are constituted of material contg. noble metal such as platinum. In such a way, the offensive odor removing capacity can be preferably enhanced. Further treating capacity of gas can be enhanced by constituting the cell having said structure of a plurality of laminated layers.
