This year's goal of this project is to establish afeasibilityassessment of the connection between pellet sintering technology and incineration fly ash solidification technology, and to improve the incineration fly ash sintered pellet formula and aggregates quality; because the energy-saving sintering technology developed by this project uses aluminum-containing thermite reaction of resource materials releases heat. In the project, relevant data collection, analysis and related tests of thermite energy-saving technology are also carried out to improve the energy-saving benefits of thermite reaction formula.
Additionally, this project will integrate the sintered pellets from incineration fly ash developed in the project, the filtrate from glass dust, and the eco-friendly binding materials developed in previous projects. These will be introduced into terrestrial vehicle demonstrations for performance evaluation and related environmental testing. The project aims to establish connections between vehicle manufacturers and resource material suppliers to facilitate the practical application of resource utilization in the future.
Regarding the purification of glass dust, the process for purifying sodium sulfate from glass dust was established in 2023. This year, the plan is to further refine the process parameters, complete tests on mixing ratios, crystallization recovery, and powder drying, and establish a trial production process to increase the batch processing capacity to 100 kilograms. Quality inspection procedures will be established to control quality. Additionally, the project will analyze domestic and international technologies for the reuse of heavy metal selenium (Se), develop processes for the separation, purification, and reduction recovery of selenium from filter residues, and use the recovered selenium as a metal pigment for verification in color board glass manufacturing. This will accelerate the future promotion and application of these technologies, reduce glass dust, and allow it to be reused in the original process.
