Intelligent exhaust gas from diesel vehicle processing system of the invention, includes exhaust purifier, sensor and automatic controller, Exhaust purifier device can reduce by 90% exhaust gas from diesel vehicle, can be fixed on vehicle chassis with anchor ear, eliminate the noise instead of former vehicle exhaust Device, acquisition of the sensor for the operating temperature, exhaust back pressure of exhaust purifier in vehicle travel process, automatic controller is to row Temperature degree, back pressure value are monitored and show, when exhaust purifier, which works, occurs abnormal, remind driver or environmental protection pipe in time Reason department is safeguarded.
Exhaust purifier of the invention is detachable structure, is divided into air inlet section, captures section, air outlet section, each section passes through flange Connection；Segmented exhaust purifier can reduce the volume of exhaust purifier, facilitate production, easy to assembly, while more convenient dimension It repairs.
Sensor of the invention, includes temperature sensor and differential pressure pickup, and temperature sensor uses high-precision and height Sensitivity K-type thermocouple, surface are coated with platinum electrode, for monitoring exhaust purifier operating temperature, temperature sensitivity 30ms, pressure For ± 1Pa；Differential pressure pickup has used high-precision and high sensitivity piezo electric module, for detecting pressure before and after exhaust purifier Difference；Described automatic controller, including shell, display screen, function button, data-interface, pcb board, software etc., mainly to sensor Acquisition signal handled, show and exhaust purifier Working Status Monitoring, alarm, the function such as data remote transmission, storage Energy；Temperature sensor and differential pressure pickup are electrically connected with automatic controller.
Its working principle is described further below: when engine exhaust enters exhaust purifier through the sound attenuation hole of air inlet pipe 1 Noise elimination cavity A, gas pressure and flow velocity decline rapidly, realizes the level-one decaying of noise.Gas passes through airflow-distribution board 5 after decaying On ring-like hole, into noise elimination cavity B, gas flow rate and pressure decline at once again after rapidly increasing, and the second level for realizing noise declines Subtract.Gas after decaying eventually passes through the aperture on oxidation catalyst carrier 6, harmful CO, HC, SOF, PM and catalysis in exhaust Oxidation reaction occurs for agent coating, is converted into nontoxic CO2 and H2O, completes the first class purification of exhaust.Gas is still after first class purification So contain a large amount of soot particulate matters, complete to capture by particle trap 7, then enters in atmosphere in fact through the exhaust pipe 9 in air outlet section The effect of existing tail gas clean-up and noise reducing.
The present invention can not only be effectively reduced by installing multiple temperature sensors and differential pressure pickup on exhaust purifier Exhaust emissions, moreover it is possible to monitor exhaust purifier service condition, set-up of control system in cockpit display screen passes through figure in time Table, sound, light prompt exhaust purifier state, when exhaust purifier, which works, occurs abnormal, can remind in time driver into Row maintenance, not only reduces the probability of exhaust purifier damage, while also improving the service life and economic performance of engine； By a large amount of entrucking tests and life test, emission performance meets European Union's 5 phase standard and 160,000 kilometers of longevity used above after entrucking Life.
