Description

Technical Field

[0001] The utility model relates to the technical field of exhaust gas particle traps, in particular to an exhaust gas particle trap with a double DPF structure. Background Art

[0002] The particle trap PDF is a ceramic filter installed in the diesel engine exhaust system. It can capture particulate emissions before they enter the atmosphere. The captured particulate emissions are then burned out during vehicle operation. Its principle is that the diesel particulate filter is sprayed with metal platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the engine exhaust particulate trap through a special pipeline, passes through the bag filter set inside, and adsorbs the carbon smoke particles on the filter made of metal fiber felt.

[0003] The announcement number CN 212838016 U discloses an exhaust gas particulate filter with a dual DPF structure, including a connecting member with an opening in it, a first shell disposed at the rear end of the connecting member, a second shell disposed at the rear end of the first shell, a third shell disposed at the rear end of the second shell, an exhaust pipe disposed at the rear end of the third shell, and a vent disposed in the exhaust pipe;

[0004] When in use, the device needs to install and connect multiple shells, which makes the disassembly and installation of the device time-consuming and labor-intensive, and makes the internal exhaust particulate capture device difficult to observe and maintain, resulting in low work efficiency. Therefore, we propose an exhaust particulate capture device with a dual DPF structure. Utility Model Content
