Zusammenfassung:The invention relates to a process equipment technique for extracting supersaturated acetylene gas from carbide slag slurry of a wet-method acetylene generator. The technique comprises feeding carbide slag slurry about 80 DEG C into a desorption tower under the state of negative pressure, doffing out acetylene gas which is adsorbed in carbide slag and water through utilizing vapor, damaging a coating layer of micro grain calcium carbide which is not broken up to be further hydrolyzed. Acetylene gas which is doffed is recycled after being processed.
