Abstract
Said invention refers to a novel high efficiency diesel engine particle trapping filtering core. Said trapping filtering core can autoregerate with high filter efficiency, no environment pollution, large intensity and small resistance, without consumption of other energy source, can be used long time with safety and reliable.
Description
Along with the development of society, people increase considerably the demand of diesel engine, but contain the carbon that does not burn in a large number in the waste gas that diesel engine is discharged, and cause black smoke emission from diesel engine, and atmosphere environment is polluted, and bring harm to human body.
In order to address this problem; diesel engine manufacturer is with improving the diesel combustion mode; increase the discharging of way minimizing soots such as oil gas atomizing ability; the dress particle trapper on outlet pipe that has comes the carbon granule in the capture in flue gas; but the filter core in the catcher; generally all be to use steinheilite; carbofrax material is done; in long-term using process; carbon granule in the waste gas can block the micropore of steinheilite and silicon carbide filter core; waste gas can't be discharged; want to reach long-term use and must take out the filter core repeated regeneration, thus up to the present also can't be real address this problem.
The objective of the invention is to solve effectively the problem that the micro particle catching filter core can automatic regeneration, make particle trapper to use for a long time.
The micro particle catching filter core is made by metallic material, and whole filter core is covered with micropore.When waste gas passed through the micro particle catching filter core, gas was discharged smoothly, and the small carbon granule in the waste gas is come out by filter element filtering, stayed the interior row of filter core and did not go out.Because metal filtering core itself is exactly with the oxidation catalytic material preparation, has catalytic capability.When oxygen and exhaust gas temperature are arranged in the waste gas greater than 200 ℃, embed carbon granule in the metal filtering core micropore and change into carbon dioxide at once and discharge, filter core is automatic regeneration just.
The process that work of the present invention is implemented is finished like this.Introduce working procedure of the present invention in detail according to figure, but automatic-regeneration particle-catching-collecting filtering core is the made by catalytic performance, whole filter core has been covered with micropore, when waste gas enters metal filtering core, gas is discharged by micropore smoothly, and the carbon granule in the waste gas is lived by metal filtering core micropore shelves, and carbon granule is embedded in to arrange in the micropore of filter core and does not go out.Because metal filtering core itself possesses catalytic capability, when exhaust gas temperature greater than 200 ℃ and when containing oxygen, carbon monoxide in the waste gas, hydrocarbon and the carbon granule that is embedded in the metal filtering core all are oxidized to the carbon dioxide discharge, and therefore metal filtering core obtains regeneration, continues periodic duty.So just finished entire work process.
The present invention is easily manufactured, and using scope is wide, and this metal filtering core purification efficiency height is present optimal capture filter core.
The present invention uses through long-term, and performance is safe and reliable, and resistance is little and filter efficiency is high.
