To realize a practical virus deactivation technique capable of deactivating a virus such as SARS-CoV-2 in gas such as expiration concerning a technique of deactivating a virus by irradiation with ultraviolet rays.SOLUTION: A control circuit 301 controls a sucking action for sucking gas possibly contaminated with a virus for a predetermined sucking time in order from an air tank 103 where the discharge of gas is completed, and a discharging action for discharging gas for a predetermined discharging time in order from an air tank 103 irradiated with ultraviolet rays for a predetermined irradiation time by an ultraviolet irradiation apparatus by controlling first fans 201 and second fans 202 of #1-#12 through relays 310 for connection and relays 320 for inversion.SELECTED DRAWING: Figure 3 【課題】紫外線を照射することによりウイルスを不活化する技術に関し、呼気等の気体中のＳＡＲＳ－ＣｏＶ－２等のウイルスを不活化できる実用的なウイルス不活化技術を実現する。【解決手段】制御回路３０１は、接続用リレー３１０および極性反転リレー３２０を介して＃１から＃１２の第１のファン２０１および第２のファン２０２を制御することにより、気体の排出が完了したエアータンク１０３から順にウイルスで汚染されている可能性のある気体を所定吸入時間ずつ吸入させる吸入動作と、紫外線照射装置により所定照射時間だけ紫外線が照射されたエアータンク１０３から順に気体を所定排出時間ずつ排出させる排出動作とを制御する。【選択図】図３
