The invention relates to a garbage
incineration fly ash high-temperature melting innocuous treatment process. The garbage
incineration fly ash high-temperature melting innocuous treatment process comprises the steps that (1) garbage
fly ash and glass
powder are mixed to prepare fly ash ball cores; (2) fly ash composite
pellets are obtained by adding
slag to coat the surfaces of the ball cores; (3)the fly ash composite
pellets are mixed with
biomass carbon to obtain mixtures; and (4) the mixtures are directly accessed into an
incineration device of an existing garbage incineration
plant for high-temperature incineration,
flue gas generated by incineration is purified by
flue gas purification equipment of the garbage incineration
plant, and incineration residue is subjected to residue treatment. According to the garbage incineration fly ash high-temperature melting innocuous treatment process, only the garbage fly ash and the glass
powder are adopted to prepare the ball cores, the ballcores are coated with
slag substances, and the obtained composite
pellets are mixed with
biomass carbon particles to form the mixtures, so that the ball forming process of the garbage fly ash is shortened and simplified,
solid melting of
heavy metals in the fly ash is facilitated, glass melts are formed, and leaching
toxicity requirements are met; and meanwhile, the required equipment is less, andthe process is matched with the existing garbage incineration
plant for implementation, so that nearby treatment of the garbage fly ash can be realized.
