Abstract

The invention relates to a diesel vehicle SCR (Selective Catalytic Reduction) system cleaning agent and a preparation method thereof. The cleaning agent is prepared from the following raw materials in percentage by mass: 3 to 10 parts of triethanolamine, 0.5 to 4 parts of dichloromethane, 6 to 12 parts of ethanol, 1 to 10 parts of polyethylene glycol, 0.3 to 0.4 part of phenoxyethanol and 50 to 60 parts of deionized water. The preparation method comprises the following steps: mixing triethanolamine, dichloromethane, ethanol, polyethylene glycol, phenoxyethanol and deionized water in proportion, heating to 50-60 DEG C, uniformly stirring, and performing ultrafiltration to obtain the diesel vehicle SCR system cleaning agent. The problems of corrosion and blockage of an existing cleaning agent are solved, environmental protection is achieved, and cost is saved.

Description

technical field [0001] The invention relates to a cleaning agent for an SCR system of a diesel vehicle and a preparation method thereof, belonging to the technical field of vehicle exhaust emission cleaning. Background technique [0002] With the implementation of the National V emission law, SCR technology has been more and more widely used in vehicle diesel engines. However, there are still some problems in this technology, such as urea crystallization and stones. Studies have shown that deposits may be generated in different parts of the SCR system, and these deposits are derived from various chemical reactions that occur on the diesel engine. Once the accumulation reaches a certain amount, it will block key parts such as the exhaust pipe, seriously affecting the normal operation of the engine. And because there may be a variety of chemical reactions in the engine, the components are complex but relatively stable, and at the same time bring problems that are difficult t...
