Problems solved by technology

[0004] In addition, in the actual use process, as the mileage of the vehicle continues to increase, more and more particles are deposited in the trap, which will inevitably increase the back pressure of the engine, thereby deteriorating the power and fuel economy of the engine.

Abstract

The invention discloses a particulate matter trapping and regenerating system applying turbulence agglomeration as pretreatment and a control method. The particulate matter trapping and regenerating system applying turbulent agglomeration as pretreatment and the control method aim to reduce the emission of particulate matters in the tail gas of a diesel engine. According to the particulate matter trapping and regenerating system applying the turbulent agglomeration as pretreatment and the control method, the particulate matters are captured by applying a turbulent agglomeration method, and meanwhile, whether particulate matter regeneration is started or not is judged by monitoring the pressure difference in real time. According to the particulate matter trapping and regenerating system applying the turbulent agglomeration as pretreatment and the control method, the particulate matters can be well discharged, and meanwhile, the back pressure of the engine is reduced.

Description

technical field [0001] The invention relates to the technical field of diesel engine tail gas treatment, in particular to a diesel engine tail gas particle collection and regeneration treatment method. Background technique [0002] With the comprehensive upgrade of the National VI emission standards, more stringent requirements have been put forward for the discharge of various pollutants. Among them, nitrogen oxides have been reduced by more than 70% compared with the National V standards, and particulate matter has been reduced by more than 50%. In order to meet the national six particulate matter emission limit requirements, adding a particulate matter trap device to the diesel engine aftertreatment system has become a necessary measure to meet the emission requirements. [0003] The particle size of the particulate matter in the exhaust exhaust of diesel engines is mostly sub-micron and nanometer levels. Experimental studies have shown that there are still a large number...
