| 摘 要： | 采用冲击式尘粒分级仪对某台5 000 t/d新型干法水泥回转窑的颗粒物排放进行了研究,以掌握颗粒物排放浓度和粒径分布情况.测试结果表明,窑头和窑尾除尘器出口排放的总颗粒物浓度分别为66.87 mg/Nm3和41.69 mg/Nm3,不能满足2010年新修订的国家标准.年排放颗粒物总量为227 t,其中PM2.5和PM10排放量分别为33.5 t和113 t.对回转窑排放颗粒物的粒径分布进行分析,发现非常符合对数正态分布规律,线性相关系数均大于0.99,窑头和窑尾排放颗粒物的中位直径分别为4.4μm和6.2μm.

| Abstract: | The emission characteristics inhalable particulate from a typical new type cement rotary kiln was studied by a seven-stage cascade impactor.The total particle concentration and particle size distribution were measured.The emission concentrations from kiln head and kiln tail were 66.87 mg/Nm3and 41.69 mg/Nm3 respectively,which could not meet the requirement of new national standards 2010.According to the calculation,this kiln emited 227 t particulate every year,which included 33.5 t PM2.5 and 113 t PM10.The particle size distributions of particulate from the kiln head and tail both accord with logarithmic normal distribution quite well and the correlation coefficients are higher than 0.99,and the median diameters are 4.4 μm and 6.2 μm respectively. |
