What car is urea, Heze urea, urea Garland car

SCR selective catalytic reduction reaction diagram is as follows: SCR reaction equation is as follows: NH2-CO-NH2 = NH3 + HNCO HNCO + H2O = NH3 + CO2 4NH3 + 4NO + O2 = 4N2 + 6 H2O 8NH3 + 6NO2 = 7N2 + 12H2O from the reaction equation can be seen, Direct reducing agent is ammonia nitrogen oxides (NH3), at 300-500 ℃, catalyst, to break down urea into ammonia. The final product of the reaction is common nitrogen air and moisture. The use of inferior car endanger urea solution typically urea solution why not replace the car with urea solution it? Because when insufficient purity urea solution of urea, particulate matter, heavy metals, minerals and other impurities present time, cause the nozzles, filters, SCR vehicle will seriously damage the system and other components, unnecessary economic losses. Such as biuret, aldehydes and other impurities insoluble matter may lead to a urea SCR system pump, the infusion tube and the clogging of the nozzle; metal ion is not contained in the urea impurity, while the SCR catalyst system has toxic effects, affect catalytic reduction of efficiency; produced by combustion deposits, clogging would skeleton catalyst, thereby reducing the efficiency of the catalyst, reduce the catalyst life. The urea solution if the concentration of the urea solution concentration deviates from the standard, not only will affect the conversion efficiency of NOX, but also due to increase urea solution crystallization point, accidents caused by pipes, nozzles, urea pump blockage.
