Problems solved by technology
[0003] In the detection of motor vehicle exhaust emission pollution, the extraction of motor vehicle exhaust is unavoidable. However, the existing motor vehicle exhaust extraction devices usually extract the motor vehicle exhaust during use, and have not been done. Other processing, which will bring inconvenience to the follow-up detection work, thus, the ideal use effect is often not achieved

The invention relates to a tail gas extraction device for motor vehicle tail gas emission pollution detection. The tail gas extraction device comprises a cylinder and a fixing frame installed in the cylinder, the head end and the tail end of the cylinder are respectively provided with an end head and a one-way valve, and a filter disc is fixedly installed in the cylinder; a suction mechanism used for absorbing motor vehicle tail gas is installed on the fixing frame, a cleaning mechanism is arranged on the side, away from the one-way valve, of the filter disc, the cleaning mechanism is connected with the suction mechanism, and a plurality of through openings used for leading out solid particles in the motor vehicle tail gas are formed in the periphery of the cylinder along the circumference. A sealing ring is movably arranged on the outer wall of the cylinder through a plurality of groups of elastic mechanisms, and the central axes of the sealing ring, the cylinder and the filter disc coincide. As the device separates solid particles and gases in motor vehicle tail gas when extracting motor vehicle tail gas, convenience is provided for subsequent detection work.
Description
technical field [0001] The invention relates to the related technical field of motor vehicle tail gas pollution detection, in particular to a tail gas extraction device for motor vehicle tail gas pollution detection. Background technique [0002] With the development of science and technology, motor vehicles have become an indispensable means of transportation in our lives, but the exhaust gas emitted by motor vehicles has become one of the main sources of polluted air. Motor vehicle exhaust contains a large number of harmful substances, including carbon monoxide, nitrogen oxides, hydrocarbons, and solid suspended particles. PM2.5, which has become the focus of social attention, belongs to the category of solid suspended particles. Therefore, the control and rectification of motor vehicle exhaust pollution is imminent, and the detection of motor vehicle exhaust is an important part of the rectification work. Motor vehicle exhaust pollution has become a worldwide public nuis...
