Abstract
A fluidized bed filter was applied to filtrate paniculate matter in diesel engine exhaust gas. Experiments were made with a single-cylinder engine to investigate the effect of gas velocity, collector size and collector depth on particulate matter and smoke filtration efficiencies and pressure drop. The results show that the fluidized bed provides high filtration efficiency of particulate matter and low-pressure drop especially under lower gas velocity. Smaller collector provides better filtration efficiency under low gas flow rate, however, the filtration efficiency drastically decreased under high gas flow rate due to excessive fluidization of collectors. Increasing collector depth gives high collection efficiency.
