Description
Technical field
The utility model relates to the auxiliary regeneration device of automobile-used grain catcher, particularly relates to a kind of auxiliary regeneration device of automobile-used grain catcher, is specifically applicable to the working life extending grain catcher.
Background technique
The main noxious emission of diesel engine is particulate matter (PM) and nitrogen oxide (NOx).Along with the upgrading of Abgasgesetz, granular material discharged limit value is more and more harsh.
Grain catcher (Diesel Particular Filter is called for short DPF) is arranged in the vent systems of diesel engine, filters the particulate matter that can significantly reduce in exhaust by physics trapping.In DPF using process, particulate matter is constantly accumulated, and exhaust back pressure is raised, engine performance deterioration.Deposited particles thing must be removed in good time, exhaust back pressure is returned to or close to original level, namely realizes the regeneration of DPF.Dpf regeneration is generally divided into initiative regeneration and passive regeneration.Initiative regeneration utilizes external energy to make delivery temperature reach the combustion temperature (500 degrees Celsius-600 degrees Celsius) of particulate matter and regenerate, and mainly contains oil spout or the regeneration of spray gas-fired combustion-supporting, electric heating regeneration, microwave heating regeneration, infrared heating regeneration etc.Passive regeneration is then the combustion temperature utilizing fuel oil additive etc. to reduce particulate matter, particulate matter is burnt at normal diesel exhaust gas temperature and regenerates.No matter be initiative regeneration or passive regeneration, the approach of expression vector regeneration is in fact all by filtered burning particulate matter.Need strict delivery temperature and concentration conditions by the regeneration of burning, under automobile-used environment, not every operating mode all can meet burning regeneration requirements.In particulate matter, ash content cannot burn simultaneously, and regeneration effect is not thorough, and long-play can reduce DPF filter efficiency, significantly improve exhaust back pressure, affects engine performance.During particulate matter excess deposition, because burning regeneration exotherm is difficult to control easily to burn DPF, blocks vent systems even completely, affect the reliability of motor and car load.
