Abstract

A system and method for clean and low-carbon in-situ disposal of waste incineration fly ash includes a waste incineration system and a fly ash disposal system. The fly ash disposal system includes a water washing system, an MVR system, and a dioxin removal system. The water washing system includes a water washing device and a press filtering device. The dioxin removal system includes a heating device, an activated carbon adsorption device, and a heat pump system. The MVR system includes a crystallizer, a heater, a vapor compressor, and other equipment. The waste incineration system is coupled with the fly ash disposal system nearby to achieve in-situ disposal of fly ash, avoiding the logistics cost and secondary pollution problems of long-distance transportation of fly ash, and greatly reducing energy and water resource consumption.
