Problems solved by technology

However, the problem with the use of urea solution for vehicles is that the urea solution for vehicles can only be used at a temperature of minus 11°C. If the temperature exceeds this temperature, the urea solution will crystallize. The result of the inability to use vehicle urea solution for nitrogen oxide removal

Abstract

The invention relates to an automobile exhaust emission purification treatment fluid. The automobile exhaust emission purification treatment fluid is prepared from the following raw materials in parts by weight: trisodium phosphate, polyethylene glycol, industrial carbamide, sodium silicate, ethidene diamine, triethanolamine, glycerol, vanadium pentoxide, AEO-9, industrial salt, ethylene glycol, a macromolecular composite synergistic agent and water. The treatment fluid can be used for catalyzing nitric oxides discharged by automotive diesel engines and quickly decomposing the nitric oxides in the presence of a surface activity catalyst, thereby achieving the practical effect of purifying the emission at any time. By adopting the treatment fluid, the exhaust finally discharged in the air can reach the national standard; meanwhile, the treatment fluid is strong in adaptability and excellent in anti-freezing effect, so that the use effect of the treatment fluid at low-temperature state of severe cold areas is still not influenced.

Description

technical field [0001] The invention belongs to the technical field of automobile exhaust emission treatment, in particular to a purification treatment liquid suitable for automobile diesel engine exhaust emission. Background technique [0002] With the continuous increase of the number of automobiles in the world, the problem of air pollution caused by automobile exhaust emissions has become a world public hazard. Diesel engine exhaust refers to the exhaust emitted by diesel engines after burning diesel oil. The exhaust gas contains hundreds of different compounds. This gas emission not only smells strange, but also makes people dizzy and nauseated, which affects people's health. Experts from the World Health Organization have determined that diesel engine exhaust, like asbestos and arsenic, is highly carcinogenic. Therefore, the exhaust pollution of diesel vehicles has reached the point of non-control. The main emissions from vehicle diesel engines are PM and NOx. Among ...
