摘要
为了解决某工程项目中粉煤灰输送系统的选型问题,从设备投资和运行电耗方面对仓泵输送系统和罗茨风机输送系统进行对比分析。结果表明,对于6个单只最大量为911 kg/h的卸灰口,输送距离为200 m的输送系统而言,仓泵输送系统比罗茨风机输送系统设备初投资多33.22万元,运行电费每年节省14.2万元,超出部分投资静态回收期为2.34 a。
To solve the selection problem of the fly ash conveying system in a certain project, the pneumatic conveying systems by silo pump and roots blower were compared and analyzed in items of equipment investment and power consumption. The results show that for 6 fly ash unloading ports with maximum discharge of 911 kg/h per port and the conveying system with conveying distance of 200 m, the equipment investment of the conveying system by silo pump is 332 200 yuan more than that by roots blower. The former can save running electricity charges of 142 000 yuan per year. The excess investments static investment period is 2.34 a.
