Diesel engine DPF cycle cleaning regeneration device

Abstract

The invention discloses a diesel engine DPF cycle cleaning regeneration device. The device comprises a cleaning tank, a clean water tank and a buffer tank, the cleaning tank is connected with the clean water tank through a first centrifugal pump, the clean water tank is connected with the buffer tank through a valve, the buffer tank is connected with the cleaning tank through a second centrifugal pump, a feeding tank and a water draining tube are arranged in the clean water tank, a circulating water pump is connected with a diesel engine DPF system through a connector, and the bottom of the clean water tank is inclined and is connected with a water draining tube. The device has the following advantages: a cyclic ultrasonic cleaning system is formed in the device, and a heating means is combined to rapidly recover the particle complementation performance of a diesel engine DPF and improve the exhaust back pressure of the above engine, so the maintenance or replacement cost of the obstructed DPF is reduced, the fuel consumption of the engine is reduced, the power of the engine is recovered, and the exhaust gas purification capacity of the DPF is recovered.

Description

technical field [0001] The invention belongs to a cleaning device, in particular to a diesel engine DPF cycle cleaning and regeneration device. Background technique [0002] At present, diesel vehicles have the advantages of low fuel consumption rate, high torque output, and wide power coverage, and are widely used in the fields of transportation and construction machinery. With the tightening of vehicle emission regulations, diesel vehicles can only meet the stringent emission regulations in the future by adopting aftertreatment devices. The emission of HC, CO, and NOx in the exhaust of diesel vehicles is less than that of gasoline vehicles. The disadvantage is that the emission of soot particles in the exhaust is higher than that of gasoline vehicles, even dozens of times higher. The solid pollutants emitted by diesel engines are mainly particulate matter, which is composed of dry soot (SOOT), soluble organic components (SOF), and a small amount of sulfuric acid and sulfa...

AI Technical Summary

Problems solved by technology

The common DPF regeneration method is to oxidize and burn the particles trapped in the DPF, but this method is easy to cause thermal damage to the filter body, and the particles produced by the lubricating oil additive package and engine wear metal cannot be removed by oxidation and combustion. As time goes by, these particles accumulate, block the DPF pores, and reduce the DPF’s particle capture ability. Cause serious environmental pollution and economic loss of DPF replacement
