The invention provides a mining vehicle emission analysis system, which comprises a sampling module, a smoke intensity detection module and a tail gas analysis module, wherein the sampling module is used for sampling vehicle tail gas; the smoke intensity detection module is in through connection with a sample gas flow output port of the sampling module; the tail gas analysis module is in through connection with the sample gas flow output port of the sampling module, the smoke intensity detection module is provided with a first tail gas input pipe corresponding to the smoke intensity detectionmodule, the tail gas analysis module is provided with a second tail gas input pipe corresponding to the tail gas analysis module, the end, which is away from the smoke intensity detection module, of the first tail gas input pipe and the end, which is away from the tail gas analysis module, of the second tail gas input pipe are gathered and communicated with the sample gas flow output port; and a particle trapping device is further arranged on the second tail gas input pipe. According to the device and the method, the components and smoke intensity of the emissions of the mining vehicle can bedetected in the same sampling process, so that the sampling synchronism of the emissions is ensured, and the analysis and detection precision can be improved.
Description
technical field [0001] The invention belongs to the technical field of detection of vehicle tail gas emissions, and in particular relates to a mining vehicle emissions analysis system. Background technique [0002] The patent document with the publication number CN102472694A discloses an exhaust gas sampling and analysis system, which can sample the exhaust gas with high pressure and analyze the components of the exhaust gas without compromising the accuracy. A vehicle exhaust nitrogen oxide detection system is disclosed, which is also a detection system for road vehicle exhaust analysis, and cannot complete smoke detection in one sampling. However, the actual working conditions of coal mining enterprises require a short detection time to reduce or remove soot particles in the discharge. It is necessary to complete the detection of smoke and waste components in one sampling as much as possible to meet the synchronization (parallelism) of discharge sampling. ) requirements...
