一、車用尿素有什么用
車(che)(che)用(yong)尿素(su)是柴(chai)油車(che)(che)使(shi)用(yong)的(de)(de)(de)(de),用(yong)于處理凈化(hua)柴(chai)油機(ji)尾氣的(de)(de)(de)(de)車(che)(che)用(yong)品,是SCR方(fang)案的(de)(de)(de)(de)必需(xu)添(tian)加(jia)劑,一(yi)般由百分之32.5的(de)(de)(de)(de)高(gao)純尿素(su)和百分之67.5的(de)(de)(de)(de)去離子水組成(cheng)。車(che)(che)用(yong)尿素(su)的(de)(de)(de)(de)用(yong)途主要(yao)有(you)(you):1、在車(che)(che)輛中主要(yao)起(qi)到(dao)凈化(hua)尾氣的(de)(de)(de)(de)作用(yong),能(neng)與尾氣中的(de)(de)(de)(de)氮(dan)氧(yang)化(hua)物(wu)發生反應,將尾氣中的(de)(de)(de)(de)氮(dan)氧(yang)化(hua)合物(wu)(NOx)催化(hua)還(huan)原成(cheng)無害的(de)(de)(de)(de)氮(dan)氣(N2)和水(H?O)排出,減(jian)少氮(dan)氧(yang)化(hua)物(wu)排放,現在對(dui)重型(xing)卡(ka)客車(che)(che)尾氣的(de)(de)(de)(de)檢測越來越多嚴格,不(bu)(bu)用(yong)車(che)(che)用(yong)尿素(su)就不(bu)(bu)達標。2、車(che)(che)用(yong)尿素(su)還(huan)有(you)(you)一(yi)個用(yong)途,那就是能(neng)優化(hua)發動機(ji)性能(neng)和燃料消耗,減(jian)少柴(chai)油消耗量可達5-7%。

三、車用尿素液配方與制作方法
1、配方:(1)普通型尿素溶液配方比例:高純尿素32.5%、去離子水67.5%。(2)防凍型尿素溶液配方比例:高純尿素32.5%、去離子水52.5%、甲醇15%。2、制作方法:將32.5%的高純尿素和67.5%的高純水進行混配,就可以得到車用尿素液體。自制車用尿素液比較麻煩,而且不一定能保證純度和雜質含量,因此還是建議大家通過正規渠道購買優質車用尿素品牌的產品。
四、車用尿素生產成本及利潤分析
車用(yong)尿(niao)素分為大桶(tong)(tong)(tong)裝(zhuang)和小桶(tong)(tong)(tong)裝(zhuang),大桶(tong)(tong)(tong)一般是(shi)噸(dun)(dun)桶(tong)(tong)(tong),每(mei)桶(tong)(tong)(tong)可以(yi)裝(zhuang)一噸(dun)(dun),主要用(yong)在自(zi)(zi)有車隊、公(gong)(gong)(gong)交公(gong)(gong)(gong)司、汽(qi)運公(gong)(gong)(gong)司、物(wu)流(liu)公(gong)(gong)(gong)司、汽(qi)修廠等(deng)(deng)等(deng)(deng),方(fang)便添(tian)加,批(pi)量采購(gou),每(mei)噸(dun)(dun)價格1600-1800元(yuan)。小桶(tong)(tong)(tong)裝(zhuang)每(mei)桶(tong)(tong)(tong)10L,每(mei)桶(tong)(tong)(tong)價格在20-30元(yuan),主要應用(yong)于(yu)加油站(zhan)、汽(qi)配城、維(wei)修廠等(deng)(deng)等(deng)(deng)汽(qi)車流(liu)動大的場(chang)所(suo),便于(yu)購(gou)買(mai)。車用(yong)尿(niao)素原料2000-2200元(yuan)/噸(dun)(dun),去(qu)離子水(shui)自(zi)(zi)己生產10元(yuan)/噸(dun)(dun)。一噸(dun)(dun)車用(yong)尿(niao)素原料加水(shui)可以(yi)出3噸(dun)(dun)尿(niao)素溶液,綜合成本約(yue)700元(yuan)每(mei)噸(dun)(dun)。每(mei)個桶(tong)(tong)(tong)4元(yuan),包材加起(qi)來10L裝(zhuang)每(mei)桶(tong)(tong)(tong)成本11元(yuan)/桶(tong)(tong)(tong)左右。市場(chang)價10L裝(zhuang)20-30元(yuan)/桶(tong)(tong)(tong)-11元(yuan)/桶(tong)(tong)(tong)成本=利(li)潤(run)(run)約(yue)9-19元(yuan)/桶(tong)(tong)(tong),大桶(tong)(tong)(tong)裝(zhuang)每(mei)噸(dun)(dun)1700元(yuan)/噸(dun)(dun)-成本700元(yuan)/噸(dun)(dun)=利(li)潤(run)(run)1000元(yuan)/噸(dun)(dun)。
五、車用尿素是什么原理
車(che)用(yong)(yong)尿(niao)(niao)素(su)(su)是指(zhi)濃(nong)度(du)為32.5%且溶劑為超純水(shui)的(de)尿(niao)(niao)素(su)(su)水(shui)溶液(ye),生產(chan)(chan)原(yuan)料為車(che)用(yong)(yong)尿(niao)(niao)素(su)(su)專用(yong)(yong)原(yuan)料和超純水(shui),它(ta)進入(ru)汽車(che)內(nei)部(bu)后(hou),通過尿(niao)(niao)素(su)(su)罐噴(pen)射系統,噴(pen)射于汽車(che)排(pai)氣管發生反應;排(pai)氣管上安裝(zhuang)(zhuang)有尿(niao)(niao)素(su)(su)計量噴(pen)射裝(zhuang)(zhuang)置,在(zai)溫度(du)達到300℃-500℃時自動噴(pen)入(ru)尿(niao)(niao)素(su)(su)溶液(ye),在(zai)催化劑的(de)作用(yong)(yong)下尿(niao)(niao)素(su)(su)(NH2CONH2)水(shui)解產(chan)(chan)生NH3和CO2,NH3與NOx反應,生成氮(dan)氣和水(shui)排(pai)出,起(qi)到凈化尾氣的(de)作用(yong)(yong)。
