Ulwazi ngesisombululo esikhethekileyo seUrea

Urea u-Urea we-Irea kwaye wayedla ngokuthetha ureame wezolimo. I-Urea i-Urea yemoto kukunciphisa i-nitrogen kunye ne-hydrogen cocaings Ineemfuno ezingqongqo ezingqinisisiweyo, ezisisiseko ezenziwe nge-Urea ePulty Poince Area kunye namanzi e-deoer. Omnye wamanqaku aphambili awona mgangatho ngumgangatho wolawulo lwemilinganiselo yokungcola. Amasuntswana, ii-ion zentsimbi, iiminerali kunye nezinye izinto zokungcola eUrea zininzi kakhulu, kwaye ingozi icacile kakhulu. Njengezwe yongezwa i-Urea engafakwanga, iya kukhokelela ekungaphumlweni kweposi, kwaye ivelise ingozi engapheliyo yokuphelisa ukuqhubekeka. Kwaye kumashumi amawaka eYuan emva kokuqhubekeka, okanye ukukhetha uphawu lwe-Urea ucetyiswe ngumenzi.

Zithini iimpawu?

Isisombululo se-Weichai I-IREA ESETYENZISIWEYO I-ISO YONYAKA YOLWAZI LOKUGQIBELA I-ISOSO22241-1, uMgangatho waseJamani Din 70070 kunye neMigangatho yeSizwe GB295518, Umgangatho wamaNgqina.

Imveliso ye-fake kunye neyona nto iphantsi: umgangatho wesisombululo we-urea akahlali, ucoceko akwanelanga, kulula ukungcola kwi-Urea, ngeli xesha, ishushu kwaye ibilisiwe kwaye ibilisiwe. Nangona kunjalo, ukusetyenziswa kwexesha elide kwe-Urea engafezekisi imigangatho yovavanyo esemgangathweni echazwe ngurhulumente iya kunciphisa ireyithi yoguqulelo lweNox, kunciphisa ukusebenza kakuhle nobomi benkqubo ye-SCR, kukhokelela ekungaphumlweni kwe-SCR.

Icocekile

Ukufezekisa iimfuno ze-URRA-righ ePiince I-Urea ePiight, isisombululo esikhethekileyo se-IICAIC kufuneka sihambe ngeendlela ezahlukeneyo zokuziqhelanisa nokuchaneka kwenkqubo yemveliso, kwaye izixhobo zokupakisha kufuneka zimahla. Umgaqo osisiseko wokuSebenza weNkqubo ye-SCR: Ukupheliswa kwe-pipet evuthayo kwi-charger turbine. Kwangelo xesha, yiyunithi ye-Urea efakwe kwi-DPF, i-Urea i-Urea iphantsi kwe-hydrolysis kunye nokuphendula kwePydrolysis phantsi kwesenzo seqondo lokuphelisa igesi, ukuvelisa i-NH3 phantsi kwesenzo se-N2 phantsi kwesenzo se-N2. Kwinkqubo yokuncitshiswa kwe-SCR, ukugxininiswa kwesisombululo se-IRE yenye yezona zinto ziphambili, kodwa uxinzelelo oluphezulu okanye olusezantsi kakhulu alunakuphucula ukusebenza kwe-nox, kodwa kuya kubangela i-ammonia kunye nokuqulunqa i-ammonia engalunganga.

Ukuguqulwa okuphezulu

Isisombululo se-IREA esikhethekileyo kunye noxinzelelo lwe-32,5% njenge-arhente yokunciphisa; Njengoqwalaselo oluqhelekileyo lwenkqubo ye-SCR-onyango, i-Area i-Akhawunti malunga ne-5% yokusebenzisa ipetroli. Thatha ubungakanani betanki lama-23 ye-23lda urea njengomzekelo, imayile inokufikelela kwiikhilomitha ezili-1500-1800.

I-Urea yongeza amanzi: Oku akunakwenzeka ngokuqinisekileyo, zininzi izinto zokungcola kumanzi empompo, kude kube ngaphaya kokuqatshelwa kwamehlo. I-calcium, i-cattcium, i-magnesium, isodium kunye nezinye izinto kwi-tap amanzi kunye namanzi amaneral kulula ukwenza izinto eziqinileyo, oko ke kuvala i-urea i-urea, ekhokelela kwiimpazamo zokwenza emva koko. Ulwelo longezwe kwi-Urea, lunokuba ngamanzi kuphela. Inqanaba le-Urea le-Urea le-Urea le-Urea liza kugcinwa phakathi kwe-30% ne-80% yomthamo opheleleyo we-Urea yetanki. Ukugcinwa kwe-Urea: isisombululo se-Irea kufuneka sigcinwe kwisitya esivaliweyo kwindawo epholileyo, eyomileyo, kude nee-oxidants ezinamandla. Xa ugcwalisa, njengokubhekiswa ngqo kwitanki ye-Urea e-Urea iqhekeza, kwaye ivelise ungcoliseko lwendalo. Kucetyiswa izixhobo zokugcwalisa izixhobo zobungcali.

Inqaku lokugcwalisa i-Irea: Isisombululo se-urea sibonisa ulusu. Ukuba ulusu okanye amehlo alongezwe, hlamba ngamanzi ngokukhawuleza; Ukuba intlungu iyaqhubeka, nceda ufunde uncedo lwezonyango. Ukuba iginyiwe ngokungakhathali, ukuthintela ukugabha, kufuna unyango lonyango ngokukhawuleza
