Abstract

The invention provides a method and device for reducing diesel particulate emissions. The method is: the gas with diesel particulate is led into the cylinder filter entocoele which is made up with many filtering elements. Then through the entocole the particulates are filtered and discharged through the leading pipe of offgas. At least one filtering element is always located in the regeneration cavity and others are in work condition. Under the effect of microwave energy, the offgas particulate is eliminated on the filtering pieces, which makes the filtering pieces reborn. The cylinder filter is rotated properly and makes the every filtering piece reborn.

Description

technical field

[0001] The invention relates to a method and a device for post-treatment of diesel engine tail gas, which can reduce the discharge of particulate matter in the diesel engine tail gas. technical background

[0002] Particulate matter (PM), which is mainly composed of soot and other substances, exists in the exhaust of diesel engines. These particulate matter are very harmful, so PM emission has become a bottleneck problem restricting the further development of diesel engines.

[0003] At present, the relatively mature method of controlling PM emissions from diesel engines is mainly internal purification, that is, through measures such as improving the structural design of the engine, improving fuel quality, optimizing fuel supply characteristics, and rationally organizing combustion to reduce its generation. However, the method of purifying PM inside the engine is approaching its limit, and the industry generally believes that only by combining exhaust post-tr...
