富氧侧吹工艺处理危废的过程分析

Process Analysis of Oxygen Enriched Side Blown Processfor Hazardous Waste Treatment

富氧侧吹工艺技术在危废资源化利用方面得到了广泛应用,尤其在有色金属危废资源化方面。本文介绍了富氧侧吹工艺的流程、设备,并分析富氧侧吹工艺处理危险废物过程的机理,包括燃烧过程、金属氧化物的还原过程、造渣过程,介绍危废主要组分如水分、有机物、硫、氟、氯、重金属元素的走向,以期更清楚地掌握该工艺优化的核心以及明确后续提高工艺水平的方向,为后续资源化利用工艺的提升提供技术支撑。

Oxygen enriched side blown technology has been widely promoted in the recycling of hazardous waste,especially in the recycling of non-ferrous metal hazardous waste.This paper introduced the process and equipment of the oxygen enriched side blown process,and analyzed the mechanism of the oxygen enriched side blown process for the treatment of hazardous waste,including the combustion process,the reduction process of metal oxides,and the slagging process.The trend of main components of hazardous waste such as water,organic matter,sulfur,fluorine,chlorine,and heavy metal elements were introduced in order to more clearly grasp the core of the process optimization and clarify the direction of subsequent improvement of the process level,and provide technical support for the subsequent improvement of the resource utilization process.
