PROBLEM TO BE SOLVED: To prevent that hazardous materials stick to dehumidification means or its neighboring structures as stain when dehumidifying air humidified with moisture used to remove odor in air.SOLUTION: In one space 9b of a storage tank 9 where purification liquid 7 is stored, air of a room 3 is discharged from an aeration pipe 5a and air bubbles 5b are gas-liquid contacted with the purification liquid 7, and odor in air is deodorized and purified by chemical reactions between the purification liquid 7 and malodorous component. The purified air humidified by a gas-liquid contact with the purification liquid 7 is dehumidified by an air dryer 11, and water droplet 11b of the moisture separated from the purified air drops from a drain outlet 11a of the air dryer 11 and is collected in another space 9c of the storage tank 9. A surface of the purification liquid 7 being exposed to an opening 9d of the another space 9c is covered with nonvolatile liquid 13 to prevent moisture evaporation of the purification liquid 7.COPYRIGHT: (C)2015,JPO&INPIT【課題】空気中の臭気を除去するのに用いる水分で加湿された空気を除湿する際に、除湿手段やその周辺の構造物等に有害物質が汚れとして付着するのを防ぐ。【解決手段】浄化液7が貯留された貯留槽9の一方の空間9bにおいて、室内3の空気を散気管5aから放出させてその気泡5bを浄化液7と気液接触させ、浄化液7と悪臭成分との化学反応により空気中の臭気を消臭し浄化する。浄化液7との気液接触で加湿された浄化空気を除湿装置11で除湿し、浄化空気から分離した水分の水滴11bを除湿装置11のドレン排出口11aから滴下させて、貯留槽9の他方の空間9cに回収する。他方の空間9cの開口9dに露出する浄化液7の液面を不揮発性液13で覆い、浄化液7の水分蒸発を防ぐ。【選択図】図2
