Inkcazelo emfutshane:

I-nitrogen oxide kwigesi yokukhupha isethi yejenereyitha ye-injini yolwandle yigesi eyenziwe yi-nitrogen kwi-cylinder kwi-cylinder kubushushu obuphezulu, obuqulunqwe ikakhulu yi-nitric oxide kunye ne-nitrogen dioxide.Ukukhuselwa kwendalo yaseGreen Valley kuphuhlise inkqubo ye-"grvnes" ye-SCR denitration yonyango lwe-nitrogen oxides kwirhasi eyinkunkuma ekhutshwa ziijenereyitha zaselwandle emva kweminyaka yophando olunzulu.Emva koyilo olukhethekileyo, inkqubo isenokuqonda ukusebenza okuphezulu phantsi kwemeko yobushushu obungazinzanga kunye nomgangatho wegesi;Amacandelo abalulekileyo anokumelana nokungcola okuqhelekileyo kwigesi yokulahla inkunkuma kunye nokuqinisekisa ukusebenza okuzinzileyo kwexesha elide lenkqubo.

Intshayelelo yobugcisa

Ukhuseleko lokusingqongileyo lwaseGrvnes luphuhlise iseti ye-"grvnes" ye-SCR denitration system yonyango lwe-nitrogen oxides kwirhasi eyinkunkuma ekhutshwa ziijenereyitha zaselwandle emva kweminyaka yophando olunzima.Emva koyilo olukhethekileyo, inkqubo isenokuqonda ukusebenza okuphezulu phantsi kwemeko yobushushu obungazinzanga kunye nomgangatho wegesi;Amacandelo abalulekileyo anokumelana nokungcola okuqhelekileyo kwigesi yokulahla inkunkuma kunye nokuqinisekisa ukusebenza okuzinzileyo kwexesha elide lenkqubo.

Ukhuseleko lokusingqongileyo lwaseGrvnes luphuhlise iseti ye "grvnes" SCR denitration system kunyango lwenitrogen oxides ekuveliseni amandla erhasi yokulahla emva kweminyaka yophando olunzima.

Iinzuzo zobugcisa

1. Isantya sokusabela ngokukhawuleza.

2. Inokuthi isetyenziswe kwi-denitration kwiqondo lokushisa eliphantsi, eliphakathi kunye neliphezulu.

3. Itekhnoloji evuthiweyo kunye nethembekileyo, ukusebenza kakuhle kwe-denitration kunye nokunciphisa ukuphuma kwe-ammonia.

4. Inaliti yeammonia efanayo, ukuxhathisa okuphantsi, ukusetyenziswa kwe-ammonia ephantsi kunye neendleko zokusebenza eziphantsi.

Ulwazi lobuchwephesha

"Ukukhangela okukhuselekileyo, ulwandle olucocekileyo kunye nokuhamba ngokulula ngakumbi" yinjongo yokusebenza kunye nenjongo yoMbutho weZizwe eziManyeneyo kunye nabasemagunyeni abanobuchule bezolwandle kwihlabathi jikelele.

Kwiinjini zedizili zaselwandle, umsi oyingozi okhutshwa ziinjini zedizili ubukhulu becala.I-NOx (apho akukho nto i-95%), i-Sox (apho i-S02 i-95% kunye ne-S03 yi-5%), i-HC, i-CH2, i-Co, i-C02 kunye nezinye iigesi kunye nokukhutshwa kwe-particulate (PM) kubangele amanqanaba ahlukeneyo omonakalo kwindalo.Kuyabonakala ukuba ukukhutshwa kombhobho we-rudder diesel yenye yezinto ezibalulekileyo ezichaphazela umgangatho womoya wehlabathi kunye nokusingqongileyo, ukuze kukhuselwe okusingqongileyo komhlaba esihlala kuwo.

I-Grvnestech iphuhlise izixhobo zokulawula umsi omnyama kunye nezixhobo zokulawula i-nitrogen oxide zokunciphisa kunye nokulawula ukungcoliseka komoya okubangelwa yi-rudder yenqanawa.

Iindlela zokunciphisa i-particle (PM) kunye ne-nitrogen oxides (NOx) zixoxwa kakhulu ngezantsi:

 

Iindlela zokunciphisa i-particle (PM):

Irhasi yenkunkuma ephathwa yi-particle trap (DPF) ephuhliswe yinkampani ye-grvnes inokufikelela kumgangatho we-lingman black level I nangaphantsi.

Iindlela zokunciphisa initrogen oxides (NOx):

Inkqubo ye-SCR denitration ephuhliswe yinkampani ye-grvnes inokufikelela kwimigangatho efanelekileyo.Inkqubo ye-Grvnes-scr denitration inokwenza ngokwezifiso iskimu sonyango lwerhasi yenkunkuma ngokuhambelana nobushushu obuhlukeneyo bokukhupha kunye nokwakheka kwegesi eyinkunkuma.
