Ulwazi ngesixazululo esikhethekile se-Urea

Imoto urea futhi imvamisa i-urea yezolimo inomehluko. I-Verealerea Urea ukunciphisa ukungcoliswa kwe-nitrogen kanye ne-hydrogen compound ekhishwa yi-Diesel Injini, futhi ibambe iqhaza ekuvikelweni kwemvelo. Inezidingo eziqinile ezifanayo, ezizokwakhiwa ngobumsulwa bokuhlanzeka kwe-urea kanye namanzi. Enye yezimpawu ezisezingeni eliphakeme yizinga lokulawula ukungcola. Izinhlayiya, i-metal ion, amaminerali nokunye ukungcola e-Urea kuningi kakhulu, futhi ukulimala kusobala kakhulu. Uma kungezwa i-urea engavunyelwe, kuzoholela ekwehlulekeni ngemuva kokusebenza, futhi kukhiqize ukulimala okubulalayo okungekho emthethweni ekusebenzeni ngemuva kokusebenza. Futhi amashumi ezinkulungwane zeYuan ngemuva kokucutshungulwa, noma ukukhetha i-Urea enconywe ngumenzi.

Yiziphi izici?

I-Weichai Special Urea Solution ihlangana ne-Iso222441-1 yamazwe omhlaba i-Din222441-1

Ukulimala kwemikhiqizo engamanga neverferior: Ikhwalithi yesixazululo ephansi ye-Urea ayiphezulu, ubumsulwa abunele, okulula ukungcola, ukuvimba i-urea nozzle, kufuthelwe futhi kubiliswe futhi kubilisiwe. Kodwa-ke, ukusetshenziswa kwesikhathi eside kwe-Urea yemoto engahlangabezani namazinga wokuhlola okusezingeni elishiwo ngumbuso kuzonciphisa isilinganiso sokuguqulwa kwe-Nox kuzonciphisa amandla okuguqulwa kwe-NOX, kunciphise ukusebenza kahle kwe-catalyst, futhi kulimaze ngokuqondile ukwehluleka kwe-sts okungekho emthethweni.

Kuhlanzekile kakhulu

Ukuze uzuze izidingo zekhwalithi ye-UREA-ephezulu kakhulu, ikhambi elikhethekile le-weichai kumele lidlule ezinhlotsheni ezahlukahlukene zokuhlunga kanye nezinhlelo zokuhlunga ngokunemba kwinqubo yokukhiqiza, kanye nezinto zokwakha ezilandelwayo kumele zibe mahhala. Isisekelo sokusebenza esiyisisekelo sohlelo lweScr: Ukuphela kwe-equant kungena ngepayipi eliphumayo kusuka kwi-turbine yeshaja. Ngasikhathi sinye, yiyunithi ye-Urea Umjovo efakwe ku-DPF, amaconsi e-urea esebenza nge-hydrolysis ngaphansi kwesenzo segesi ephezulu yokushisa igesi, ekhiqiza i-NH3 edingekayo, i-NH3 yehlisa i-NH3 ngaphansi kwesenzo se-Catalyst. Ohlelweni lokunciphisa i-SCR, ukugcwaliswa kwe-urea solution kungenye yezinto ezibalulekile, kepha ukugxila okuphezulu kakhulu noma okuphansi kakhulu akunakuthuthukisa ukusebenza kahle kwe-nox, kepha kuzokwenza isiliphu se-ammonia kanye nokwakhiwa kwe-pollant pollant amonia.

Ukuguqulwa okuphezulu

Ngesixazululo esikhethekile se-urea ngokuhlushwa okungu-32.5% njengokunciphisa i-ejenti; Njengokuhlelwa okujwayelekile kohlelo lwe-SPS lwe-POST-Treatment SCROPTION, ukusetshenziswa kwe-Urea Kubalelwa ku-5% ukusetshenziswa kwamafutha. Thatha umthamo wethangi le-23lde ureas njengesibonelo, imayela lingafinyelela kumakhilomitha angu-1500-1800.

Urea engeza amanzi: Ngokuvamile umuntu ubuza ukuthi u-Urea angangeza amanzi amaminerali, amanzi abilisiwe abilisiwe nezinye izinto. Lokhu akwenzeki, kunokunye ukungcola kwamanzi kampompi, kude kakhulu nokubhekwa kwamehlo okunqunu. I-calcium, i-magnesium, i-sodium nezinye izinto empompini wamanzi namanzi amaminerali kulula ukwakha izinto eziqinile, ngaleyo ndlela ivimba ama-nozzle e-urea, okuholela emaphutheni angemva kokusebenza. Uketshezi lungezwe e-urea, lungaba ngamanzi anobuhlakani kuphela. Izinga le-Urea Tank Liquid lizogcinwa phakathi kwama-30% nama-80% wevolumu eliphelele lethangi le-urea. Isitoreji se-Urea: Isixazululo se-Urea kufanele sigcinwe esitsheni esivaliwe endaweni epholile, eyomile, kude nama-oxidants aqinile. Lapho kugcwaliswa, njengokuqonde ngqo ethangi lokulahla i-Urea Splashing, futhi kukhiqize ukungcoliswa kwemvelo. Kunconywa imishini yokugcwalisa okhokhelwayo.

Qaphela ukugcwalisa urea: Isixazululo se-Urea siyawohloka esikhunjeni. Uma isikhumba noma amehlo engeziwe, hlambulula ngamanzi ngokushesha okukhulu; Uma izinhlungu ziqhubeka, sicela ufune usizo lwezokwelashwa. Uma ugwinywa ngokunganaki, kwenqabela ukugabha, funa ukwelashwa ngokushesha
