The dry acetylene process is to spray water in a mist state onto calcium carbide powder with a theoretical amount of water for hydrolysis to produce powdered calcium carbide slag with water content of 4-10% and temperature of 90-96 deg.c. When the carbide slag is transported into the carbide slag buffer bin, the moisture in the high-temperature carbide slag absorbs the heat in the carbide slag to be vaporized and is discharged from the vent hole of the carbide slag buffer bin. Because the carbide slag has light weight, small granularity and high temperature, when entering the carbide buffer bin, carbide slag dust is discharged from the exhaust hole along with water vapor flow.

The main component of the carbide slag dust is calcium hydroxide, the carbide slag dust has high humidity, and can generate easily caked calcium carbonate by reacting with CO2 in the air, so the traditional gas dust removal equipment is easily blocked due to the characteristics of high humidity, high viscosity, easy caking and the like of the carbide slag dust, and has limitation on long-term stable use. If the problem of discharging carbide slag dust is solved by sealing the vent hole of the carbide slag buffer bin, trace acetylene gas contained in the carbide slag can be gathered in the carbide slag buffer bin, so that explosion risk factors exist.
