Abstract

The invention provides a device system integrating DPF (diesel particulate filter) heat regeneration and mechanical regeneration, comprising an engine, a DPF active regeneration system, and a diesel particulate filter; the DPF active regeneration system is connected with the intake end of the diesel particulate filter through a first exhaust pipe, and the engine system is connected with the intakeend of the diesel particulate filter through a second exhaust pipe, the exhaust end of the diesel particulate filter is connected with a third exhaust pipe, wherein the DPF regeneration system is characterized in that a fuel outlet of a fuel tank is connected with a fuel inlet of a fuel pump through a fuel pipe, a fuel outlet of the fuel pump is connected with a fuel inlet of an oil-level adjusting valve through a fuel pipe, a fuel outlet of the oil-level adjusting valve is connected with a turbine combustor through a fuel pipe, and the turbine combustor is connected with the intake end of the diesel particulate filter through the first exhaust pipe. The device system combining mechanical regeneration and heat regeneration has compact structure, DPF regeneration efficiency can be improved, PDF' service life can be extended, and the cost of the DPF regeneration system is reduced.

Description

technical field [0001] The invention relates to the technical field of particulate trap regeneration, in particular to a device system integrating DPF thermal regeneration and mechanical regeneration. Background technique [0002] As the number of diesel vehicles and the pressure of environmental pollution are increasing day by day, the standards for controlling diesel engine exhaust emissions are becoming more and more stringent. DPF (Diesel Particulate Filter) technology is currently the most effective method to meet the emission requirements of diesel engine exhaust regulations on particulate matter. DPF (Diesel Particulate Filter) technology mainly makes exhaust gas pass through the filter material arranged in the exhaust pipe, and uses the principle of collision, adsorption, interception or gravity sedimentation to separate particulate matter from the airflow. With the accumulation of particles on the filter material, the filter holes will be blocked, the exhaust resis...
