THE INDUSTRIAL TEST OF PULSE BAG FILTER IN PETROLEUM COKE SUPERFINE GRINDING PROCESS |

| Abstract: | 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. |
