| 摘 要： | 滚筒筛筛分是生活垃圾分选中常用的工艺,国内目前有关滚筒筛分选生活垃圾的研究尚不多见.因此,本实验通过自行设计的一台处理能力为150kg.h-1的滚筒筛,采用实际生活垃圾进行分选实验,确定最佳运行参数范围.结果表明,当滚筒筛孔径为120mm时,在V实测/V极限（V实测为滚筒转动时实时测定转速,V极限为物料与滚筒一起转动时...

| Abstract: | The trommel screener is often used to separate MSW (municipal solid waste). However, MSW separation utilizing trammel screener is seldom reported in China. In this study, a trommel screener with a separation capacity of 150 kg MSW per hour was designed and its optimal operational parameters were determined. The optimum separation efficiencies can be reached when the ratio of Vobservation/Vextremity ranged from 0.51 to 0.73 and roller angle 5.3°to 7.0°for 120 mm of mesh diameter, 0.33 to 0.60 and roller angle 4.3°to 7.8°for 80 mm of mesh diameter, and 0.51 to 0.60 and roller angle 3.2°to 6.0°for 40 mm of mesh diameter, respectively. The separation efficiencies of trommel screener were observed to be closely related to L (length of roller), D (screener inner-diameter) and L/D. The optimum separation efficient can be reached that for L/D ranged from 2.5 to 3.0, slightly over 3.3, and much higher than 3.3, the corresponding D were 120 mm, 80 mm and 40 mm respectively. |
