In order to address the challenges of poor reaction activity, difficult high-value disposal, and low comprehensive utilization of coal-based solid waste such as gasification ash, fly ash, and coal gangue, this project proposes a new method for the high-value utilization of coal-based solid waste through the synergistic combination of micro-scale chemical engineering and acoustic field stimulation in the context of industrial solid waste resource utilization and large-scale consumption demand. By constructing a microchannel continuous flow reactor and developing a micro-scale efficient mixed chemical process for coal-based solid waste, the activation reaction efficiency is improved. By integrating ultrasonic transducer elements, the multi-phase flow and energy-mass transfer characteristics in the microchannel are regulated to achieve the high-value disposal of coal-based solid waste through the coupling of multiple physical fields. The ultrasonic microchemical production system is utilized to achieve the cascade conversion of silicon, aluminum, calcium, iron, and carbon resources, thereby improving the comprehensive utilization of coal-based solid waste.

This project will conduct research on the synergistic enhancement of microchannel chemical reactor continuous flow and ultrasonic transducer-assisted stimulation for the high-value utilization of coal-based solid waste. Different types of coal-based solid waste will be studied to elucidate the decomposition and reconstruction mechanism of the silicon, aluminum, calcium, iron, and carbon chemical network structure, reveal the evolution of waste component structure under multiple physical field conditions and its impact on material properties, and clarify the structure-property relationship of the products, providing technical support and theoretical basis for the high-value, large-scale, and clean cascade utilization of coal-based solid waste.
