摘要:
为了探究煤灰颗粒从金属板上脱落的影响因数,自建实验平台,记录了煤灰颗粒振打脱落过程以及每次振打中煤灰脱落质量,探究了机械振打除灰中振打敲击力大小对振打除灰的影响,以及不同煤灰厚度对最小有效振打力的影响. 结果显示,在振打冲击金属板时,煤灰颗粒脱落存在“分层现象”和“分阶段现象”,而且随着振打力的增加各阶段之间的分界越模糊;煤灰颗粒脱落的质量向前几次振打冲击集中;煤灰的厚度越大,最小有效振打力越小,当煤灰厚度为1 mm、2 mm、3 mm和4 mm时,最小有效振打力分别为65.3 N、36.9 N、25.9 N和17.0 N.
Abstract:
To study the influence factors of coal ash particles falling from the metal plate, the experimental platform was built to record the falling process and the falling mass of the particles. The influence of rapping force on the mechanical rapping ash-removal and the effect of the coal ash thickness on the minimum effective rapping force were both explored. The results show that there are stratification and stage phenomenon in the process of coal ash dropping when knocking the metal plate and the boundary between different stages was blurred with the increase of the rapping force; meanwhile, the mass of the particles of coal ash falling off concentrates on previous knockings; the greater the thickness of the coal ash, the smaller the minimum effective rapping force. The minimum effective rapping forces are 65.3, 36.9, 25.9 and 17.0 N, respectively when the thickness of the coal ash layer is 1,2,3 and 4 mm.
