Abstract:
An injection chelating treatment method for waste incineration fly ash, mainly using a deacidifying system to inject directly a solid powder fly ash chelating agent into smoke so as to mix the chelating agent directly with the smoke powder to complete the chelating process of the fly ash in the smoke.
