AI Technical Summary
Technical Problem
The existing exhaust gas detectors are not filtered before detection, which causes large particles such as dust in the exhaust gas to block the detection probe rod and affect their use.
Method used
A exhaust gas detection device is designed. By setting a filter net and a brush in the detection pipeline, the filter net is located in front of the detection probe rod, and the brush is driven by the impeller to clean up the dust on the filter net and ensure the smooth flow of the detection pipeline.
Benefits of technology
The exhaust gas is pre-filtered through the filter to protect the detector and avoid particulate blockage; the brush cleans the filter, keeping the detection pipeline unobstructed, and improving the detection accuracy and equipment life.

Abstract
The invention discloses a tail gas detection device. The device comprises a detection pipeline; a detection probe rod of the tail gas detector is located in the detection pipeline; the filter screen is coaxially installed in the detection pipeline, and the detection probe rod is located between the filter screen and the outlet end of the detection pipeline; the two sets of impellers are arranged on the two sides of the filter screen respectively, the impellers and the filter screen are coaxially arranged, brushes are fixed to the tail ends of rotating shafts of the impellers, and a pair of brushes abut against the two sides of the filter screen; the filter screen is used for filtering tail gas in the detection pipeline and can filter the tail gas and protect the tail gas detector before the tail gas is in contact with the detection probe rod, the brush is used for cleaning the filter screen and can keep the detection pipeline unobstructed, and the impeller is arranged to drive the brush to rotate and clean the filter screen, so that the detection pipeline is more smooth. And the impeller is driven by the tail gas flow, the structure is simple, and energy can be effectively saved.
