Abstract
The invention relates to the technical field of treatment on calcium carbide broken dust and particularly relates to a system for producing acetylene gas by using recycled calcium carbide dust. The specific process is characterized by recycling calcium carbide dust on the ground, lifting the calcium carbide dust to a dust storage bin via a primary feeder for collecting, feeding the calcium carbide dust into a feeding hopper via a secondary feeder, adding the calcium carbide dust into an acetylene generator at the bottom of the feeding hopper, enabling the calcium carbide dust to carry out chemical reaction with supernate in the acetylene generator to generate acetylene gas, filtering the generated acetylene gas via a washer and a water seal, then feeding the acetylene gas into an acetylene gas conveying pipeline, metering the acetylene gas via a flow gauge, then safely feeding the acetylene gas into an acetylene process gas cabinet, and returning the acetylene gas to production. Through the system for producing acetylene gas by using recycled calcium carbide dust, the utilization rate of the calcium carbide is increased; the pollution of the calcium carbide dust to the environment is reduced; the potential safety hazard is eliminated.
