High efficiency and saving cost technology on potassium recovery and evaprationg from the sintering flue ash in steel plant, which is headche on how to treat the sintering machine ash wastment.
DEFINITION
This scheme focuses on the resource utilization of Sintering head ash from iron and steel enterprises (hereinafter referred to as "head ash"), with the core goal of extracting fertilizer-grade potassium salt (potassium chloride) and sodium salt (sodium chloride), while taking into account iron resource recovery and environmental protection compliance.
Integrated long-process steel mills both domestically and internationally are currently confronted with prominent bottlenecks regarding sinter flue dust disposal. Tightening environmental regulations prohibit random landfill of such residues. Long-term open-air stockpiling not only occupies valuable land and exposes enterprises to hefty compliance fines, but also generates zero economic returns, making this a persistent environmental headache for steel producers.
