| Abstract: |
| This paper investigated and compared the gross-efficiency of purification, efficiency of sizing particles purification, stability of operation, safety of exploitation and economy of three types of filtration cores in the practical condition. Through test data evaluation, the result showed that the special designed nickel-based metal filtration core with the effects of penetration & interception is more competent than that of fiber filtration core with the effects of coalesce in the CBM purification featured with high flow velocity, variable concentration of dusts and water-containing, and it has technology and economy advantages. |
