AI Technical Summary
In existing technologies, dechlorination treatment methods for fly ash from municipal solid waste incineration suffer from high costs, equipment corrosion, and uneven heating, which affect the quality of ceramic products and the stable operation of equipment.
A gradient heating method was adopted to heat fly ash at low, medium and high temperatures through a multi-stage cyclone preheating cylinder. Combined with countercurrent heat exchange in the cyclone preheating cylinder, chloride salts were gradually volatilized. The waste heat of the high-temperature flue gas from the sintering mechanism was used for heating and dechlorination to prepare ceramic microspheres.
It reduces the risk of equipment corrosion, improves dechlorination efficiency, reduces water resource usage and treatment costs, extends equipment life, and ensures uniform heating of fly ash and dispersion performance of ceramic microspheres.
