搅拌机使用车用尿素的原因

混凝土搅拌机用尿素用于减少尾气排放,保护大气环境。车辆使用尿素将废气中的有害氮氧化物还原为氮和水。配备尿素系统的柴油车需要一个尿素容器来盛装尿素液体。根据发动机转速、燃油喷射量等数据计算理论产生的氮氧化物量。根据化学反应比,计算出处理这些氮氧化物所需的氨气量,进而计算出需要喷射的尿素量,然后控制喷射系统将尿素喷射到高温排气端排气,以消除氮氧化物。
Urea used in concrete mixer is used to reduce tail gas emission and protect atmospheric environment. The vehicle uses urea to reduce the harmful nitrogen oxides in the exhaust gas to nitrogen and water. Diesel vehicles equipped with urea system need a urea container to contain urea liquid. Calculate the amount of nitrogen oxides generated theoretically according to the engine speed, fuel injection volume and other data. According to the chemical reaction ratio, calculate the amount of ammonia required to treat these nitrogen oxides, and then calculate the amount of urea to be injected, and then control the injection system to inject urea to the high-temperature exhaust end for exhaust to eliminate nitrogen oxides.
当组合仪表出现工作灯时,需要检查并添加尿素。部分车辆在用完尿素后可能无法启动。当指示灯亮时,立即添加尿素。在一般车辆中,添加完成后,指示灯会在一定距离后熄灭。
When the work light appears in the instrument cluster, it is necessary to check and add urea. Some vehicles may not start after running out of urea. When the indicator light is on, add urea immediately. In normal vehicles, the indicator light will go out after a certain distance after the addition.
要知道车用的尿素是针对柴油机的车辆,搅拌机大多使用柴油机。因为柴油机会排放有害气体氮氧化物,会造成环境污染。人体长期吸入这种废气会对人体造成很大伤害。为了减少这种危害,使用柴油机的搅拌机应添加车用尿素。车用尿素添加有催化作用。发生化学反应,将氮氧化物转化为待排放的氮气和水。
We should know that the urea used in vehicles is for diesel vehicles, and most mixer vehicles use diesel engines. Because diesel will emit harmful gas nitrogen oxides, which will cause environmental pollution. Long term inhalation of this waste gas will cause great harm to human body. In order to reduce this hazard, truck urea should be added to the mixer truck with diesel engine. The addition of vehicle urea has a catalytic effect. Chemical reaction occurs to convert nitrogen oxides into nitrogen and water to be discharged.

相关排放标准已在多地实施,搅拌机的排放与车用尿素密不可分。车用尿素是一种柴油车尾气处理液。车用尿素主要用于吸收柴油车尾气中的氮氧化物,也是SCR工作过程中的关键环节。
Relevant emission standards have been implemented in many places, and the emission of mixer truck is closely related to vehicle urea. Vehicle urea is a kind of diesel vehicle exhaust treatment fluid. Vehicle urea is mainly used to absorb nitrogen oxides in diesel vehicle exhaust, and it is also a key link in the working process of SCR.
车用尿素对混凝土搅拌机的动力和油耗起着关键作用。如果不给车加尿素,或者使用纯度不够、质量差的尿素溶液,都会导致发动机自动减速。同时,劣质车用尿素会污染SCR催化反应罐中的催化剂,造成后处理系统部件的损坏。您知道,后处理系统的维护成本可能相当昂贵。这种做法不仅增加了对环境的破坏,也增加了搅拌机的使用成本。
Vehicle urea plays a key role in the power and fuel consumption of concrete mixer. If urea is not added to the vehicle, or urea solution with insufficient purity and poor quality is used, the engine will slow down automatically. At the same time, inferior automotive urea will pollute the catalyst in the SCR catalytic reaction tank and cause damage to the components of the aftertreatment system. As you know, the maintenance cost of the aftertreatment system can be quite expensive. This practice not only increases the damage to the environment, but also increases the use cost of the mixer.
