Abstract
The invention relates to a method for generating electricity through recovering metallurgical slag afterheat. A metallurgical slag tank loaded with molten metallurgical slag is carried to an afterheat recovering device; the slag is overturned onto a slag loading platform of the afterheat recovering device; a metallurgical slag stirring device is started to stir, disperse and cool the metallurgical slag; meanwhile, an afterheat recovering gas hood water cooling system is started; the water cooling system absorbs the heat energy of the metallurgical slag to change normal-temperature water into high-temperature vapor; the vapor is collected by a gas pocket via a pipe; the gas pocket outputs constant-high pressure and high temperature vapor to a generator set for generating the electricity; and after the heat energy of the metallurgical slag in the afterheat recovering device cannot be used for taking the heat, a new metallurgical slag tank is continuously overturned. The method uses the afterheat of the metallurgical slag for generating the electricity; the afterheat of the metallurgical slag is clean energy having such characteristics as no pollution and low cost; and the method is continuous in heat energy and huge in heat value, truly realizes the energy reutilization, and solves such problems as metallurgical slag heat energy and water wastes in the traditional water fetching cooling process.
