Decarbonization method and device for diesel engine exhaust gas carbon granule collector

Abstract

The invention discloses decarbonization method and device for a diesel engine exhaust gas carbon granule collector (Diesel Particulate Filter, DPF). The decarbonization method comprises the steps of producing an oxyhydrogen gas through water electrolysis, mixing the oxyhydrogen gas with methyl alcohol subjected to ultrasonic atomization, combusting under the control of an automatic methyl alcohol,ejecting through a fire nozzle, utilizing an induced draft fan on the back part of a DPF rotating work table for forming an air channel, enabling an induced draft fan for combusting and cleaning theinner wall of the carbon granule collector, combusting and melting carbon deposits on the inner wall of the carbon granule collector by utilizing the catalytic combustion characteristics of activatedhydrogen ions and hydroxyl ions, and discharging under the washout of moisture formed after hydroxyl ion combustion. The decarbonization method provided by the invention has the advantages of high decarbonization efficiency, no damage on the inner wall of the carbon granule collector, low us cost, no pollution on the environment and the like. The device provided by the invention comprises an oxyhydrogen gas oxyhydrogen gas system, a methyl alcohol ultrasonic atomization device, a three-way connector, an automatic igniter, a combustion nozzle, the DPF rotating work table, the induced draft fanand an electrical control device.

Description

technical field [0001] The invention relates to a method and device for removing carbon by hydrogen and oxygen for a diesel engine exhaust carbon particle collector. The inner wall of the carbon particle collector is burned and cleaned by a hydrogen-oxygen flame, and the catalytic combustion characteristics of hydrogen ions and hydroxide ions are used to absorb carbon particles in the The carbon particles on the ceramic filter melt and fall off under the scouring action of the water vapor formed after the combustion of hydrogen and oxygen, eliminating the carbon deposit on the DPF. Background technique [0002] Automobile exhaust is an important factor causing air pollution. In order to eradicate smog, my country has implemented strict exhaust emission standards. Compared with gasoline engines, diesel engines have lower carbon monoxide and hydrocarbon emissions, while nitrogen oxides and particulate matter are much more serious than gasoline engines. At present, diesel engin...
