消煙装置における界面活性剤の結果

Abstract

When fires occur in high buildings, inside tunnels, etc, the interior fills with smoke and it becomes impossible to see. To cope with such situations, a well known and widely applied remedy is to use a corona electric discharge to attract the smoke particles to the inner walls and absorb them there. In the past the authors have shown how this smoke removing effect can be enhanced by improvements to sprinklers. In the present experiment they added interface activation substances to the water issuing from sprinklers and conducted tests to correlate the effect of these additives with the diameter of the water globules. In the case of the improved sprinkler, it was found that the best results could be obtained with small water globules and a cationic active agents type of interface activation additive.
