AI Technical Summary

Technical Problem

Existing technologies are insufficient to effectively suppress dioxin generation during lead-based solid waste smelting, and end-of-pipe pollution control methods have high investment and operating costs, making it difficult to achieve ultra-low emissions.

Method used

By reducing the Cu and Cl content in lead-based solid waste, controlling the flue gas temperature and atmosphere in the furnace during the smelting process, and adding dioxin inhibitors, such as sulfur-based inhibitors, to the furnace, the formation of dioxins can be suppressed.

Benefits of technology

This technology has enabled the suppression of dioxin formation during the smelting process, simplified procedures, reduced investment and energy consumption, met environmental protection requirements, and achieved source control.
