After-Treatment for Reduction of Diesel Exhaust Particulate 2001-01-3204
Three types of after-treatment for reduction of diesel exhaust particulate are investigated mainly about their characteristics of filtration and regeneration. They are ceramic foam filter (CFF) and microwave regeneration (MR), stainless steel net trap with electrostatic collector (SSNTEC) and reverse jet regeneration (RJR) with high pressure gas, wall flow ceramic filter (WFCF) and infrared heating regeneration (IHR). With the data from experiments, the filtration efficiency of CFF is up to 60% and the efficiency of MWR reach 80% upward. The average efficiency of SSNTEC is about 60% and the efficiency of RJR is just 55%. WFCF and IHR have outstanding performance, the efficiency of WFCF reach 90% upward and its IHR is complete.
