Aiming at the safety the safety, efficiency, maintenance and cost issues caused by release and enrichment of residues acetylene and moisture condensation during the production process of environmental protection desulfurizer prepared by dry calcium carbide slag recovery, the research idea based on research core of the residues acetylene release and moisture condensation rule and operation core of the temperate and humidity control is pushing out along the train of thought like laboratory research -- establishment of mathematical model -- numerical simulation -- safe and efficient separation process of calcium carbide slag. The law of acetylene release from dry calcium carbide slag and the hygroscopicity and dew-forming behavior of dry calcium carbide slag will be studied, and the corresponding mathematical models will be established. Combining with the numerical simulation of the whole process of the dry calcium carbide slag short-range recovery system, the safe and efficient separation process for the dry calcium carbide slag recovery system was established by monitoring the residual acetylene and the water direction in the whole process. Through the control of temperature and humidity, achieve the reasonable, accurate control of residual acetylene and moisture, reduce the system safety risk and production, maintenance costs, ensure the process is stable and efficient.
