Removal of Smoke and Toxic Gases Through Sprinkler Head Spray

Abstract

This study was conducted with the aim of reducing the concentration of smoke and toxic gases by quickly capturing large amounts of these substances using a venturi tube and sprinkler head in a fire. To this end, a new experimental model sprinkler head has been developed. The ability to remove carbon monoxide and smoke was tested using a standard sprinkler head with a scaled-down chamber and smoke of cigarettes. The carbon monoxide concentration and visibility were measured at 1, 2, and 3 min after filling the chamber with smoke. The proto-model confirmed a significant drop in the carbon monoxide concentration and a remarkable smoke dilution at a discharge pressure of 0.1 MPa. Therefore, the test model could extend the evacuation time and stay time by removing smoke and toxic gases.
