Experimental Investigation on Electrostatic DPF 2001-01-0194
A new kind of diesel particulate after-treatment system (EDPF) has been developed. It uses stainless steel nets as the particulate trapping part and uses reverse blowing unit combining with centrifugal collector as the regeneration part. In order to improve the filtering efficiency of stainless steel nets, corona-discharging technology is applied to charge particles before the stainless steel nets. The test result on the 6110 Diesel bench scale shows that the filtering efficiency of the EDPF system can reach to about 70% and the EDPF system is successful.
