攪拌機使用車用尿素的原因

混凝土攪拌機用尿素用于減少尾氣排放,保護大氣環境。車輛使用尿素將廢氣中的有害氮氧化物還原為氮和水。配備尿素系統的柴油車需要一個尿素容器來盛裝尿素液體。根據發動機轉速、燃油噴射量等數據計算理論產生的氮氧化物量。根據化學反應比,計算出處理這些氮氧化物所需的氨氣量,進而計算出需要噴射的尿素量,然后控制噴射系統將尿素噴射到高溫排氣端排氣,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.
當組合儀表出現工作燈時,需要檢查并添加尿素。部分車輛在用完尿素后可能無法啟動。當指示燈亮時,立即添加尿素。在一般車輛中,添加完成后,指示燈會在一定距離后熄滅。
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.
要知道車用的尿素是針對柴油機的車輛,攪拌機大多使用柴油機。因為柴油機會排放有害氣體氮氧化物,會造成環境污染。人體長期吸入這種廢氣會對人體造成很大傷害。為了減少這種危害,使用柴油機的攪拌機應添加車用尿素。車用尿素添加有催化作用。發生化學反應,將氮氧化物轉化為待排放的氮氣和水。
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.

相關排放標準已在多地實施,攪拌機的排放與車用尿素密不可分。車用尿素是一種柴油車尾氣處理液。車用尿素主要用于吸收柴油車尾氣中的氮氧化物,也是SCR工作過程中的關鍵環節。
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.
車用尿素對混凝土攪拌機的動力和油耗起著關鍵作用。如果不給車加尿素,或者使用純度不夠、質量差的尿素溶液,都會導致發動機自動減速。同時,劣質車用尿素會污染SCR催化反應罐中的催化劑,造成后處理系統部件的損壞。您知道,后處理系統的維護成本可能相當昂貴。這種做法不僅增加了對環境的破壞,也增加了攪拌機的使用成本。
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.
