Background

Fly ash is fine ash collected from flue gas generated after coal combustion, and is main solid waste discharged from coal-fired power plants. Along with the development of the power industry, the discharge amount of fly ash under coal burning and electricity is increased year by year, and the fly ash becomes one of industrial waste residues with larger discharge amount in China at present. A large amount of fly ash can generate dust without treatment, thereby polluting the atmosphere; if discharged into a water system, the river can be silted, and toxic chemicals in the river can cause harm to human bodies and organisms. However, the fly ash can be recycled, such as being used as an admixture of concrete and the like. At present, flue gas and cinder generated after coal is combusted easily drop into a pipe for collecting fly ash to influence fly ash collection, and the flue gas after the fly ash is collected can be discharged into the atmosphere after being filtered again to prevent residual fly ash in the flue gas from influencing the natural environment; on the other hand, when the fly ash is used as an admixture, the fly ash can be used only by being naturally air-dried, so that the time is long and the efficiency is low.
