Problems solved by technology

However, using an external heat source to heat the particle trap to achieve regeneration not only requires a lot of energy consumption, but also occurs when the heating is insufficient during the regeneration process, or the trap is ablated due to excessive heating
Reverse high-pressure blowback requires the particle filter to be removed from the engine exhaust system. The regeneration process is complicated and difficult to disassemble.
Vibration regeneration will cause mechanical damage such as cracking and damage to the filter body of the trap

Abstract

The invention relates to a diesel particle filter regenerating unit and a control method for the regenerating unit, and belongs to the technical field of diesel particle filter regenerating. The diesel particle filter regenerating unit and a control method for the regenerating unit are characterized in that an regenerating electric control unit (ECU) judges the regenerating opportunity according to the a exhausting pressure difference and a temperature difference of the upstream and the downstream of the diesel particle filter; while regenerating, the ECU controls a magnetic valve, a sewage tank magnetic valve, a high pressure pump, a rotary motor and a high pressure pulse rotary undershoot nozzle at the two ends of the diesel particle filter to conduct high pressure water pulse jet cleaning; water is injected into the inner cavity of the diesel particle filter, and ultrasonic generator is started to conduct ultrasonic vibration cleaning; and regenerating sewage flows into an sewage tank, exhausting thermal energy is utilized to evaporate the regenerating sewage, and centralized harmless treatment is conducted on soot accumulation. According to the regenerating control method for the regenerating unit, through high pressure rotary jet, combined with the ultrasonic vibration, regenerating of the diesel particle filter is achieved, and the service life can be prolonged effectively.

Description

technical field [0001] The invention relates to a particle trap regeneration device and a control method thereof, in particular to a rotating high-voltage pulse recoil ultrasonic oscillation particle trap regeneration system and a control method thereof, belonging to the technical field of particle trap regeneration. Background technique [0002] After the State Environmental Protection Administration fully implemented the fourth-stage motor vehicle pollutant emission standards nationwide in July 2013, the National V and National VI emission regulations, which have stricter requirements on vehicle pollutant emissions, have also been introduced one after another. The above-mentioned emission regulations, without exception, put forward stricter requirements on the particle emission limits of automobiles. In this context, major engine OEMs and automobile OEMs have invested a lot of research on off-machine purification in order to ensure that automotive products can meet the lat...
