  • 摘要: 新型污泥喷雾干化-回转窑焚烧工艺是将脱水污泥通过雾化喷嘴形成滴雾后与高温烟气并流接触达到干化后再进行焚烧的集成技术。干化过程中湿污泥中有机物的挥发及该新型工艺的运行工况和污染物减排效果成为污泥处理处置领域关注的焦点。在对污泥喷雾干化焚烧工艺原理分析基础之上,对我国600 t/d新型污泥喷雾干化焚烧示范项目进行封闭式现场取样监测,通过成分分析、毒性监测等重点对污染物去除效果进行了研究,结果表明,该工艺通过自动控制可将出口烟气温度和干化污泥温度保持较稳定的状态,分别为(96±10)℃和(72±8)℃;喷雾干化塔内不存在粉尘爆炸危险,TVOC3;直接干化热利用率>80%,优于间接干化;烟气排放口各指标均满足《生活垃圾焚烧污染控制标准》(GB18485-2001)的要求。
    Abstract: The new spray drying/incineration process is an integrated technique which was designed based on our country’s national conditions to utilize the high temperature flue gas to dry the dewatered sludge. The pollutants removal and performance of this new process has become a focus. Therefore, we determined the running performance and pollutant removal of the new sludge spray drying/incineration demonstration project with capacity of 600 t/d for sludge treatment. The results show that the temperatures of flue gas and dried sludge particles remain stable at (96±10)℃ and (72±8)℃, respectively, under the automation control. There is no dust explosion risk in the spray drying tower and TVOC concentration is below 0.025 mg/m3. The direct contact between high temperature flue gases with spayed wet sludge makes the drying process rapid and thermal reuse efficiency as high as 80%. The indicators of the discharged flue gas can meet the Solid Waste Incineration Pollution Control Standard (GB18485-2001).
