ARTIFICIAL RAINFALL TYPE AIR CLEANING DEVICE

To provide an artificial rainfall type air cleaning device which is intended for an indoor space of a relatively large building such as a gymnasium and an auditorium and can effectively clean air in the indoor space, and is easily maintained and inspected.SOLUTION: An artificial rainfall type air cleaning device has a device body 1 imparting humidity to air in a partitioned space, and removing contaminated substances floating in air. The device body 1 has artificial rainfall means 15 comprised of: a nozzle 11 generating rainfalls by scattering droplet groups; a water receiving tank 12 receiving the artificial rainfalls; water sending means 13 comprising a water sending pipe 13A and a water sending pump 13B sending the water of the water receiving tank 12 to the vibration nozzle 11; and an underframe 14 holding these items. The air cleaning device also has water cleaning means making indoor air circulate by a descending airflow which descends together with the descending droplet groups from the vibration nozzle 11, and cleaning water for the vibration nozzle 11 in advance.SELECTED DRAWING: Figure 1 【課題】体育館や講堂等の比較的広い建物の室内空間を対象として、当該室内の空気の清浄化を有効に成し得る保守点検が容易な人工降雨式空気清浄装置を、提供すること。【解決手段】本発明にかかる人工降雨式空気清浄装置は、区画された空間内の空気に湿度を与え且つ空気中を浮遊する汚染物質を除去する装置本体１を有する。この装置本体１は、水滴群を放散して人工降雨を作る振動ノズル１１と、この人工降雨を受けとめる受水槽１２と、この受水槽１２の水を前記振動ノズル１１に送り込む送水管１３Ａ及び送水ポンプ１３Ｂを備えた送水手段１３と、これらを保持する台枠１４とから成る人工降雨手段１５を有する。更に、振動ノズル１１からの降下水滴群と共に下降する下降空気流で空間内空気を循環させ、同時に、振動ノズル１１用の水を予め浄化する水浄化手段を装備した。【選択図】図１
