The invention relates to a replaceable motor vehicle exhaust particulate removing system which comprises an exhaust inlet, an exhaust emptying port, a particulate trap housing, a filtering body, a differential pressure sensor, a by-pass pipe and a safety valve, wherein the particulate trap housing is arranged between the exhaust inlet and the exhaust emptying port; the filtering body is arranged in the particulate trap housing, and used for trapping particulates; the differential pressure sensor is arranged between the exhaust inlet and the exhaust emptying port, and used for measuring filtering pressure drop, namely exhaust back pressure, of the filtering body; the by-pass pipe is arranged between the exhaust inlet and the exhaust emptying port; the safety valve is arranged in the by-pass pipe, and used for opening and closing the by-pass pipe; and when the exhaust back pressure is greater than a first preset threshold and the preset time is reached, the safety valve is opened, so that exhaust is discharged into an atmosphere directly by the by-pass pipe. The system removes the particulates, ensures the reliable operation of an engine, and is an effective measure for coping with the motor vehicle exhaust particulate discharging pollution at present.
Description
technical field [0001] The invention belongs to the technical field of post-treatment of engine exhaust gas, and in particular relates to a replaceable system for removing particulate matter in exhaust gas of motor vehicles. Background technique [0002] At present, the problem of inhalable particulate matter in the atmosphere is becoming more and more serious, and the source of particulate matter emitted by motor vehicles is one of the main sources. As far as the post-treatment technology of motor vehicle exhaust particulate matter is concerned, the particle filter (DPF) is an effective emission reduction measure. This technology can effectively capture more than 90% of the particles in the exhaust gas. The most direct and effective method for particulate matter is also the most widely used particulate matter reduction technology in the world. The DPF is installed on the engine exhaust pipe. When the exhaust gas passes through the DPF, the particulate matter is filtered an...
