Problems solved by technology

However, once the particles accumulated on the filter start to oxidize and burn in a suitable temperature and oxidizing atmosphere, the temperature can be as high as 2000 ° C, and it is easy to melt the ceramic carrier of the trap
In addition, if the particles trapped by the trap are not removed regularly, the filter element will be clogged and the back pressure of the diesel engine will rise sharply, which will affect the performance of the diesel engine.

Embodiment 1

[0020] Embodiment 1, Figure 1~Figure 2 Provided is a filtering composite plasma catalytic treatment diesel engine PM reactor and method, which mainly includes a soot particle trap and a soot particle processing device, and the soot particle processing device includes an anode device and a cathode device.

[0021] The soot particulate trap is a filter cloth bag 1, which is provided with an air inlet, and the air inlet and the cavity (that is, the built-in cavity of the filter cloth bag 1) are connected to each other (the air is discharged into the cavity through the air inlet). Diesel engine exhaust or other exhaust gas containing soot particles that need to be treated); in order to improve the high temperature resistance of the bag, the material used for the filter bag 1 is polytetrafluoroethylene fiber. At the same time, in order to increase the treatment efficiency of diesel engine soot particles, the catalyst TiO2 is loaded on the filter bag 1, and the catalyst TiO2 can be...

Abstract

The invention discloses a reactor for filtering composite plasma catalytic treatment diesel engine PMs (particulate matters). The reactor comprises a soot particulate catcher, wherein an air inlet and a cavity are arranged in the soot particulate catcher, the air inlet is communicated with the cavity, a soot particulate treatment device is also arranged on the soot particulate catcher and comprises a cathode device and an anode device, the cathode device is arranged in the cavity, and the anode device is arranged outside the soot particulate catcher in a way of corresponding to the cathode device.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a filter composite plasma catalytic treatment diesel engine PM reactor and a method. Background technique [0002] Diesel engines have high combustion efficiency, high power and long service life, and are widely used in vehicles, machinery, ships and various power devices, but their exhaust gas contains soot particles (PM), hydrocarbons (HC), CO and nitrogen oxides (NOx) and other pollutants. Because of the high O2 content in the exhaust, the HC and CO emissions of diesel engines are less, generally only 1 / 10 of gasoline engines; NOx emissions are roughly in the same order of magnitude as gasoline engines; and PM emissions are about 30 times that of gasoline engines ~50 times. Since PM is only sub-micron in size, almost all of it can be inhaled into the human body, which is extremely harmful to human health, so its treatment has become the top prior...
