Abstract
Abstract Ammonia (NH3) is a typical toxic and hazardous gas that is easy to cause explosion, poisoning and pollution due to accidental release. This paper studies the water curtains scavenging the dispersion of ammonia by conducting experiments in confined space. The time profile of NH3 concentration in air was analysed. Firstly, the free dispersion experiments for NH3 in confined space were conducted to study the scavenging effectiveness of the water curtain. Secondly, a series of experiments were carried out to explore the factors affecting the scavenging efficiency of water curtains. The results showed that the water curtains can scavenge most ammonia gas and reduce the sustained time of ammonia gas dispersion. The scavenging efficiency of a water curtain can reach 90%. The scavenging efficiency of fan spray nozzles was similar to that of cone nozzles. When the water pressure increased from 0.05 MPa to 0.2 MPa, the scavenging efficiency would increase from 83-88% to 92-94%.
