Abstract

The invention discloses a diesel engine DOC / POC cleaning and regenerating agent and an application thereof. The cleaning and regenerating agent comprises a solvent, a carbon deposit dissolving agent, anti-redeposition agent, a wetting agent, a foaming agent and a rust proofing and corrosion inhibiting agent. The cleaning and regenerating agent can be applied to a regeneration process of a catalytic reactor with carbon deposit blockage. The cleaning and regenerating agent has the advantages of extremely good cleaning effects, and safety and environmental protection without pollution; at the same time, the cleaning and regenerating agent can be applied to a regeneration process of an invalid diesel engine DOC / POC catalytic reactor with carbon deposit blockage due to bad fuel oil quality and incomplete combustion, dissolving, dispersion and cleaning can be safely and efficiently carried out for carbon deposit, soot, colloid, greasy filth and other deposits in a catalyst without dismounting, so that maintenance cost of the catalytic reactor is reduced, oil consumption of a diesel engine is reduced, engine power is recovered, and tail gas purifying effects of the DOC / POC catalytic reactor are improved.

Description

technical field [0001] The invention belongs to the field of cleaning agents, in particular to a diesel engine DOC / POC cleaning and regeneration agent and its application. Background technique [0002] The emissions of HC, CO, and NOx in the exhaust of diesel vehicles are less than those 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 fraction (SOF), a small amount of sulfuric acid and sulfate, etc. With the continuous increase of global diesel vehicle production, the exhaust emission of diesel vehicles has attracted great attention from the governments of various countries. Strict diesel vehicle exhaust emission regulations have been formulated at home and abroad. Implement Euro IV, Euro V and Euro VI diesel vehicle exhaust emiss...
