Exhaust gas purification device of diesel vehicles

The utility model discloses an exhaust gas purification device of diesel vehicles, which comprises a sleeve, a side-flow type heat reactor arranged in the sleeve, an exhaust gas recirculation (EGR) and secondary air supply device, a straight-flow type heat reactor and a metal honeycomb carrier catalyst. A plurality of flow guiding plates with adsorptive capability, a driving rod and a vibration motor are arranged in the straight-flow type heat reactor, each level plane is provided with only one flow guiding plate, a plurality of adsorptive holes are arranged on each flow guiding plate, and the tail end of each flow guiding plate is connected with the driving rod which is connected with the vibration motor. The vibration motor drives the driving rod to move vertically, thereby enabling the flow guiding plates to achieve self resonance under the effects of the driving rod and shaking off carbon smoke particles adsorbed on the surfaces of the flow guiding plates. The vibration motor is connected with an external
