Exhaust purification device of electric self-purification diesel vehicle

Abstract

The invention relates to the field of electromechanics and specifically relates to an exhaust purification device of an electric self-purification diesel vehicle. The exhaust purification device comprises a front end cover, a sleeve, secondary air supply devices, Venturi tube devices, a vibrating motor, a drive rod, a metal honeycomb carrier catalyst, a thermal insulating layer, flange holes, a deflector, a gas inlet and a rear end cover; the flange holes are formed in two upper and lower end faces of the front end cover; the sleeve is fixed between the front end cover and the rear end cover; the secondary air supply devices, the Venturi tube devices and the metal honeycomb carrier catalyst are all arranged within the sleeve; one end of the deflector is connected with the Venturi tube devices, while the other end of the deflector is connected with the metal honeycomb carrier catalyst through the drive rod; the drive rod is connected with the vibrating motor; the air inlet is formed in the sleeve; the thermal insulating layer is arranged between the honeycomb carrier catalyst and an inner surface of the sleeve; when the vibrating motor drives the drive rod to move, the drive rod drives the deflector to achieve self-resonance, so that adsorbed soot particles can be shaken off.

Description

technical field [0001] The invention relates to the electromechanical field, in particular to an electric self-purifying diesel vehicle exhaust purification device. Background technique [0002] At present, diesel vehicles are widely used in various industrial fields of society due to their high thermal efficiency, good fuel economy, large low-speed torque, long service life and low maintenance costs. However, as the number of diesel vehicles increases year by year, the problem of air pollution caused by them is becoming more and more serious. In order to meet the requirements of the upcoming new emission regulations for motor vehicles, various enterprises and scientific research institutions are trying their best to develop new technologies to deal with diesel vehicles. Exhaust pollution problems of diesel vehicles Existing diesel vehicle exhaust purification devices are of various types, most of which can only do single purification, but for diesel vehicle exhaust gas cont...

However, as the number of diesel vehicles increases year by year, the problem of air pollution caused by them is becoming more and more serious. In order to meet the requirements of the upcoming new emission regulations for motor vehicles, various enterprises and scientific research institutions are trying their best to develop new technologies to deal with diesel vehicles. Exhaust pollution problems of diesel vehicles Existing diesel vehicle exhaust purification devices are of various types, most of which can only do single purification, but for diesel vehicle exhaust gas containing multiple harmful components, the purification ability is limited and cannot meet the requirements of future emission regulations. The effect of purifying all the harmful components of the air
