一、車用尿素有什么用
車(che)用(yong)(yong)尿素是(shi)柴(chai)油(you)(you)車(che)使用(yong)(yong)的(de)(de)(de)，用(yong)(yong)于處理凈(jing)化(hua)(hua)(hua)柴(chai)油(you)(you)機(ji)尾氣(qi)(qi)(qi)(qi)的(de)(de)(de)車(che)用(yong)(yong)品，是(shi)SCR方案的(de)(de)(de)必(bi)需添加劑(ji)，一般由百(bai)分(fen)之32.5的(de)(de)(de)高純(chun)尿素和百(bai)分(fen)之67.5的(de)(de)(de)去(qu)離子水(shui)組成(cheng)。車(che)用(yong)(yong)尿素的(de)(de)(de)用(yong)(yong)途主要有：1、在車(che)輛中(zhong)主要起到(dao)凈(jing)化(hua)(hua)(hua)尾氣(qi)(qi)(qi)(qi)的(de)(de)(de)作(zuo)用(yong)(yong)，能(neng)與尾氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)氮氧化(hua)(hua)(hua)物發生反應，將尾氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)氮氧化(hua)(hua)(hua)合(he)物（NOx）催(cui)化(hua)(hua)(hua)還(huan)原成(cheng)無害的(de)(de)(de)氮氣(qi)(qi)(qi)(qi)（N2）和水(shui)（H?O）排(pai)出，減(jian)少氮氧化(hua)(hua)(hua)物排(pai)放，現在對(dui)重型卡(ka)客車(che)尾氣(qi)(qi)(qi)(qi)的(de)(de)(de)檢測越(yue)(yue)來(lai)越(yue)(yue)多嚴格，不用(yong)(yong)車(che)用(yong)(yong)尿素就不達(da)標。2、車(che)用(yong)(yong)尿素還(huan)有一個用(yong)(yong)途，那就是(shi)能(neng)優化(hua)(hua)(hua)發動機(ji)性能(neng)和燃料消耗，減(jian)少柴(chai)油(you)(you)消耗量可達(da)5-7%。
二、車用尿素生產設備多少錢一臺
生產(chan)(chan)車用(yong)(yong)尿素(su)需要的(de)(de)設(she)(she)(she)備(bei)(bei)(bei)眾多，包括純水生產(chan)(chan)設(she)(she)(she)備(bei)(bei)(bei)、尿素(su)液(ye)生產(chan)(chan)設(she)(she)(she)備(bei)(bei)(bei)、成(cheng)品過(guo)濾設(she)(she)(she)備(bei)(bei)(bei)、灌裝設(she)(she)(she)備(bei)(bei)(bei)、擰蓋設(she)(she)(she)備(bei)(bei)(bei)以及(ji)生產(chan)(chan)日期(qi)批(pi)號打碼設(she)(she)(she)備(bei)(bei)(bei)，一(yi)(yi)套(tao)(tao)(tao)車用(yong)(yong)尿素(su)設(she)(she)(she)備(bei)(bei)(bei)中，主要的(de)(de)就是純水生產(chan)(chan)設(she)(she)(she)備(bei)(bei)(bei)、尿素(su)液(ye)生產(chan)(chan)設(she)(she)(she)備(bei)(bei)(bei)和成(cheng)品過(guo)濾設(she)(she)(she)備(bei)(bei)(bei)，核心設(she)(she)(she)備(bei)(bei)(bei)就是EDI反滲透系統，這也是整套(tao)(tao)(tao)機(ji)器比(bi)較貴的(de)(de)部(bu)件，具體價(jia)格看它的(de)(de)生產(chan)(chan)廠家和規(gui)格型號，小型的(de)(de)大概1-3萬元(yuan)一(yi)(yi)套(tao)(tao)(tao)左右，中等規(gui)模的(de)(de)大概是4-8萬元(yuan)一(yi)(yi)套(tao)(tao)(tao)，大規(gui)模生產(chan)(chan)車用(yong)(yong)尿素(su)的(de)(de)設(she)(she)(she)備(bei)(bei)(bei)則(ze)比(bi)較貴，要十幾萬元(yuan)甚(shen)至幾十萬元(yuan)一(yi)(yi)套(tao)(tao)(tao)。
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(che)用(yong)(yong)尿素(su)分(fen)為(wei)大桶(tong)(tong)(tong)(tong)(tong)裝(zhuang)和(he)小(xiao)桶(tong)(tong)(tong)(tong)(tong)裝(zhuang)，大桶(tong)(tong)(tong)(tong)(tong)一(yi)般是(shi)噸(dun)(dun)(dun)桶(tong)(tong)(tong)(tong)(tong)，每桶(tong)(tong)(tong)(tong)(tong)可(ke)以裝(zhuang)一(yi)噸(dun)(dun)(dun)，主要用(yong)(yong)在自(zi)有車(che)隊、公交公司(si)(si)、汽運公司(si)(si)、物流公司(si)(si)、汽修廠等等，方便添加(jia)(jia)(jia)，批(pi)量(liang)采(cai)購(gou)，每噸(dun)(dun)(dun)價(jia)(jia)格1600-1800元(yuan)(yuan)(yuan)(yuan)。小(xiao)桶(tong)(tong)(tong)(tong)(tong)裝(zhuang)每桶(tong)(tong)(tong)(tong)(tong)10L，每桶(tong)(tong)(tong)(tong)(tong)價(jia)(jia)格在20-30元(yuan)(yuan)(yuan)(yuan)，主要應(ying)用(yong)(yong)于加(jia)(jia)(jia)油站、汽配(pei)城(cheng)、維修廠等等汽車(che)流動大的場所，便于購(gou)買。車(che)用(yong)(yong)尿素(su)原料(liao)2000-2200元(yuan)(yuan)(yuan)(yuan)/噸(dun)(dun)(dun)，去離子水自(zi)己生產10元(yuan)(yuan)(yuan)(yuan)/噸(dun)(dun)(dun)。一(yi)噸(dun)(dun)(dun)車(che)用(yong)(yong)尿素(su)原料(liao)加(jia)(jia)(jia)水可(ke)以出3噸(dun)(dun)(dun)尿素(su)溶液，綜合成本(ben)(ben)約700元(yuan)(yuan)(yuan)(yuan)每噸(dun)(dun)(dun)。每個桶(tong)(tong)(tong)(tong)(tong)4元(yuan)(yuan)(yuan)(yuan)，包材(cai)加(jia)(jia)(jia)起來10L裝(zhuang)每桶(tong)(tong)(tong)(tong)(tong)成本(ben)(ben)11元(yuan)(yuan)(yuan)(yuan)/桶(tong)(tong)(tong)(tong)(tong)左右。市(shi)場價(jia)(jia)10L裝(zhuang)20-30元(yuan)(yuan)(yuan)(yuan)/桶(tong)(tong)(tong)(tong)(tong)-11元(yuan)(yuan)(yuan)(yuan)/桶(tong)(tong)(tong)(tong)(tong)成本(ben)(ben)=利潤約9-19元(yuan)(yuan)(yuan)(yuan)/桶(tong)(tong)(tong)(tong)(tong)，大桶(tong)(tong)(tong)(tong)(tong)裝(zhuang)每噸(dun)(dun)(dun)1700元(yuan)(yuan)(yuan)(yuan)/噸(dun)(dun)(dun)-成本(ben)(ben)700元(yuan)(yuan)(yuan)(yuan)/噸(dun)(dun)(dun)=利潤1000元(yuan)(yuan)(yuan)(yuan)/噸(dun)(dun)(dun)。
五、車用尿素是什么原理
車用尿(niao)(niao)素(su)(su)是指濃度為(wei)32.5%且溶劑為(wei)超(chao)純(chun)水(shui)的尿(niao)(niao)素(su)(su)水(shui)溶液，生(sheng)產原料為(wei)車用尿(niao)(niao)素(su)(su)專(zhuan)用原料和(he)超(chao)純(chun)水(shui)，它(ta)進入汽車內部后，通過(guo)尿(niao)(niao)素(su)(su)罐(guan)噴(pen)(pen)射系統，噴(pen)(pen)射于汽車排(pai)(pai)氣管發生(sheng)反應(ying)；排(pai)(pai)氣管上安(an)裝有尿(niao)(niao)素(su)(su)計量噴(pen)(pen)射裝置，在溫(wen)度達到300℃-500℃時自動噴(pen)(pen)入尿(niao)(niao)素(su)(su)溶液，在催化劑的作用下尿(niao)(niao)素(su)(su)（NH2CONH2）水(shui)解產生(sheng)NH3和(he)CO2，NH3與NOx反應(ying)，生(sheng)成氮(dan)氣和(he)水(shui)排(pai)(pai)出，起到凈化尾氣的作用。
