| 英文摘要 | Dry-process calcium carbide slag is a large amount of calcium-based solid waste produced in the process of making acetylene by the calcium carbide process, in which residual calcium carbide and acetylene gas have a greater impact on resource utilization. Focusing on the hidden safety problem caused by the acetylene gathering, the physical and chemical properties of dry calcium carbide slag were analyzed. The changes of residual calcium carbide content and the influences of different temperature, humidity, vibration, open time, gas replacement and other factors on the escape behavior of acetylene gas were investigated. The results show that the main component of calcium carbide slag is calcium hydroxide, and the particle size is concentrated below 75 碌m. The morphology of the slag is polyhedral and loose sheet-like. The residual amount of calcium carbide in the slag fluctuates from 0 to 0.71%. The increase of temperature and moisture can promote the escape of acetylene gas from calcium carbide slag. Vibration has no obvious promotion or suppression effect, moreover, most acetylene can escape from calcium carbide slag with the combination of hanging and air replacement. Through this method, the explosion risk caused by the gathering of acetylene gas can be effectively reduced. The research can provide a reference for the storage, transportation and utilization of calcium carbide slag in the industrial production process. 漏 2021, Editorial Board of CIESC Journal.
