A dpf high-efficiency deflagration cleaning regeneration method, control system and device

Abstract

The invention discloses a DPF efficient detonation cleaning regeneration method. The DPF efficient detonation cleaning regeneration method comprises the following specific steps: (S1) firstly, a regeneration device and a control system are assembled and wired; then, a startup / stop button is pressed down; electric level of a startup / stop input port of a single-chip microcomputer is overturned; through on-off output signals of a high-pressure clean air inlet switching valve of a single-chip microcomputer plate, the high-pressure clean air inlet switching valve is driven to act by a peripheral isolation amplifying relay; and the DPF efficient detonation cleaning regeneration method relates to the technical field of diesel oil particle filter regeneration. The DPF efficient detonation cleaningregeneration method, a control system and a device can guarantee of the hydrogen and oxygen concentration in a DPF within a safe and effective range; the detonation is formed in the DPF through ignition to burn particles as CO2; meanwhile, high pressure is instantly generated to discharge remained impurities in the DPF from an outlet of the DPF; hydrogen and oxygen are burnt to generate water vapor without generating new particles; an electric control system reads real-time data through a sensor and automatically judges the cleaning effect; and the service life of the DPF is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of diesel particle filter regeneration, in particular to a DPF high-efficiency deflagration cleaning regeneration method, control system and device. Background technique [0002] DPF is a diesel particulate filter, which refers to a device installed in the exhaust system of a diesel vehicle to reduce particulate matter (PM) in the exhaust by filtering. DPF can effectively purify 70%-90% of the particles in the exhaust. One of the most effective and direct methods for particulate matter, the technical characteristics and difficulties of DPF: After a certain amount of particulate matter is captured by the particulate filter, it will block the exhaust passage, causing the exhaust back pressure to rise and affect the engine performance. The particles that have been collected are removed to restore the exhaust gas to normal, which is called regeneration. There are many regeneration methods, one of which is passiv...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a DPF high-efficiency deflagration cleaning and regeneration method, control system and device, which solves the need to consume fuel or electricity, so the economic efficiency of the DPF diesel engine used is poor, and the user needs to add additives to the diesel. Sulfur in fuel will form sulfate at high temperature, resulting in increased particle emissions. Secondly, sulfate adheres to the surface of the carrier coating, destroys the coating, produces toxic and harmful substances, hinders the gaseous catalytic reaction and makes regeneration invalid, thereby causing particulate matter emissions The problem of exceeding the standard
