Abstract
- Given the severe pollution caused by particulate matters in diesel engine exhaust, we discuss herein the problem of exhaust back-pressure and regeneration of commonly used diesel particulate filter treatment technology. This paper proposes a method based on water film adsorption to remove exhaust particles from exhaust gas. Particulates flowing through the purification device are adsorbed by the continuous isobaric water film formed on the wave adsorption plate. The formation process and characteristics of the equal pressure-differential water film are studied through combined theoretical analysis and experimental verification. The regeneration process and influencing factors of the purification system are also analyzed, and the treatment of the device is verified. Experiments show that the device offers a better purification of exhaust particulates with lower exhaust resistance and regeneration of the system during the treatment.
