1results about How to "Reduce the liquid-solid ratio" patented technology

This invention relates to the field of solid waste treatment technology, and in particular to a method for multi-stage countercurrent water washing and dechlorination of waste incineration fly ash with a low liquid-to-solid ratio. This invention combines low liquid-to-solid ratio water washing with countercurrent water washing, and utilizes a rotary vibrator to achieve effective dechlorination of waste incineration fly ash, ultimately obtaining water-washed fly ash with a chlorine content of less than 1%. Compared with existing technologies, this invention organically combines low liquid-to-solid ratio water washing, countercurrent water washing, and a rotary vibrator, balancing dechlorination efficiency and water resource utilization. The process is stable and reliable, simple to operate, and has low energy consumption. The treated fly ash meets the requirements for subsequent resource utilization, providing an efficient and feasible new solution for the harmless treatment and resource recovery of waste incineration fly ash.
