垃圾焚烧飞灰旋风炉高温熔融处理技术

阐述了目前我国垃圾焚烧处理过程中飞灰处理所存在的问题。提出了一种已获得国家发明专利的垃圾焚烧飞灰旋风炉高温熔融处理及再生利用新技术。在一台75t/h旋风炉上的试验结果证明,该项技术能够分解飞灰中99.9%以上的二恶英,急冷熔渣、静电除尘器捕集灰以及尾气中二恶英含量分别为1-2ng-TEQ/kg、25-26ng-TEQ/kg和0.033ng-TEQ/m3。急冷熔渣及静电除尘器捕集灰中的重金属浸出毒性远低于国家环保标准,可作为建筑材料使用。采用煤粉作为辅助燃料,因而运行成本低,焚烧产生的热量经余热锅炉发电,可给企业创造可观的经济效益,符合目前国内垃圾焚烧厂实际情况。

Cyclone Furnace Technology Disposing Fly Ash from MSW Incineration Plant

The situation of MSW incineration was reviewed and fly ash disposal problem was put forward at present in this paper.A new technology was put forward to dispose of fly ash harmlessly using cyclone furnace at high temperature, which has been patented in China.Experimental results carried out in a 75t/h cyclone furnace confirmed that it has advantages of decomposing more than 99.9% dioxins in fly ash, The dioxins in molten ash cooled by water and fly ash from ESP and flue gas were 1-2ng-TEQ/kg, 25-26 ng-TEQ/k...
