White smoke generating apparatus and method of using the same |
摘要 |
The present invention provides a white smoke generating apparatus for generating white smoke of a stable density unaffected by air temperature or humidity conditions. The apparatus comprises an apparatus main body 11 being provided with a white smoke discharge opening 11a; a cryogenic liquefied gas supply mechanism 12 for supplying a cryogenic liquefied gas into the apparatus main body 11; and a humidifying mechanism 13 for humidifying the atmosphere inside the apparatus main body. The cryogenic liquefied gas supply mechanism 12 is provided with a first pipeline 18 which communicates a cryogenic liquefied gas reservoir 16 and a cryogenic liquefied gas emission nozzle 17 placed inside the apparatus main body 11, preferably at the white smoke discharge opening 11a side. The humidifying mechanism 13 comprises a second pipeline 24 which branches from the first pipeline 18 and communicates with a spray nozzle 21 placed inside the apparatus main body 11 for spraying water, and a third pipeline 28 which branches from the second pipeline 24 and communicates with the spray nozzle 21 via a water reservoir 25. A cryogenic liquefied gas vaporizer 22 is provided inside the second pipeline 24 upstream from the point where the third pipeline 28 branches from the second pipeline 24. |
