宝鸡发电厂综合分场,由西北电力设计院设计了一条干粉煤灰输送线。粉煤灰由罗茨风机、螺旋灰泵,经φ219毫米管道(总长约250米)输送至500米~3的粉煤灰贮库内。经过十多年使用,运行良好。但粉煤灰输送量较小,小时输送量约1.5～2.5吨,昼夜三班运行,最大输送量为50吨,很不适应生产的需要。 Baoji Power Plant General Branch was designed by Northwest Electric Power Design Institute to design a dry fly ash conveyor line. Fly ash is transported by a Roots blower, auger pump, through a φ219 mm pipe (a total length of approximately 250 meters) to a fly ash depot of 500 m-3. After more than a decade of use, it works well. However, the amount of fly ash transport is small, the hourly delivery volume is about 1.5-2.5 tons, and the three-shift operation is carried out day and night. The maximum delivery volume is 50 tons, which is not suitable for production needs.
