PURPOSE:To surely sterilize floating bacteria in the air and adhereing bacteria by executing piping of a spray nozzle fitting tube in which plural pieces of two-fluid nozzles for mixing a disinfectant with compressed air and spraying it as ultrafine grain of specific average grain size are arranged in parallel at necessary parts in a hospital, and spraying the disinfectant so that the inside of a space becomes a saturated state. CONSTITUTION:A spray nozzle fitting tube 21' to which nozzles 20 are attached at required intervals is provided along a ceiling, etc., at necessary parts in a hospital. Also, to each spray nozzle fitting tube 21',a disinfectant supply tube 50 and a compressed air supply tube 51 are connected. Subsequently, to the disinfectant supply tube 50 and the compressed air supply tube 51, a disinfectant tank and a compressor are connected, respectively. In such a state, the disinfectant whose average fine grain size is <=10mum, mixed with compressed air, is sprayed from the nozzle 20 by such extent of spray quantity that the inside of a space becomes a saturated state. Accordingly, a floating time in the air of the disinfectant becomes long, and after floating in the air, the disinfectant adheres to the wall surface, and the surface and the reverse side of an apparatus. In such a way, floating bacteria in the air and adhereing bacteria can be sterilized surely. |
