Experimental study of low pressure water mist atomization characteristics
Abstract: This article uses the Winner318 laser particle size analyzer in school laboratory. Under different conditions to distribute water mist particle size. Aims to select the best and most suitable particle size distribution conditions so that it can produce the best fine mist extinguishing effect. The experiments use control single-variable method to study pressure, nozzle height and additives for water mist particle size. Experimental data show that: with increasing pressure water mist particle size becomes smaller; Using different types of nozzles, adjust height of the nozzle , mist particle size will be different; Under same pressure, the additive-containing fine mist particle size smaller than water; Addition, different types of additives on the water mist has different effects . Also, different concentrations of additives on water mist particle size has different affected.
