摘　　要：利用超细粉碎分级设备,分别测试粉碎工艺中除尘器在不同过滤面积、过滤风速、入口粉尘浓度时,喷吹后的除尘器阻力、过滤风速、喷吹时的除尘器阻力波动情况;测试脉冲宽度对喷吹后除尘器阻力和喷吹时除尘器阻力波动的影响。结果表明:由于石油焦的轻质和黏附性特性,过滤风速不应超过2.17 m/min,考虑到除尘效率和经济效益,最好控制在1.3 m/min以内;除尘器入口粉尘浓度的高低对喷吹后除尘器阻力和喷吹时除尘器阻力波动均存在较大影响,入口粉尘浓度低时,阻力和阻力波动都较小;脉冲宽度对喷吹后除尘器阻力和喷吹时除尘器阻力波动有一定影响,该实验系统最佳脉冲宽度为0.08 s。Using superfine crushing grading equipment,the dust resistance after injecting,filtration speed and the dust resistance fluctuation when blowing in grinding process were tested.The test conditions were respectively different filtration area,different filtration speed,different filter inlet dust concentration and different pulse width.The results showed that for petroleum coke is light and has adhesion,the filtration speed should not exceed 2.17 m/min.And considering the dust removal efficiency and economic benefit,the filtration speed should better be controlled in 1.3 m/min.Both the filter inlet dust concentration and the pulse width had certain influence on the dust resistance after injecting and the dust resistance fluctuation when blowing.The dust resistance and the dust resistance fluctuation were small,when the filter inlet dust concentration was low.And pulse jet filter exists a best pulse width,0.08 s is the best one for this experimental filter.
