Acetylene dissipated in the slurry melting process can be collected by additionally arranging a fan, and the concentration of the acetylene in the slurry melting tank is controlled. However, in the exhaust process of the fan, the mixed water vapor of the scattered carbide slag powder can adhere to the pipeline and the fan impeller, and the normal operation of the equipment is seriously influenced.
