b) Ukusebenza kakuhle konyango, akukho lungcoliseko lwesibini.Izinga lokuhlanjululwa kwerhasi yenkunkuma yezinto eziphilayo ephathwa ngendlela yokutshisa i-catalytic ngokuqhelekileyo ingaphezulu kwe-95%, kwaye imveliso yokugqibela ayinabungozi i-CO2 kunye ne-H2O, ngoko akukho ngxaki yesibini yongcoliseko.Ukongezelela, ngenxa yokushisa okuphantsi, isizukulwana se-NOx sinokuncitshiswa kakhulu.
Ukuthumela ngenqanawa, ukuPakisha kunye nokugcinwa
a) I-Xintan inokuhambisa i-VOC catalyst ngentsimbi ehloniphekileyo engaphantsi kwe-5000kgs phakathi kweentsuku ezi-7.
b) Ukupakishwa: Ibhokisi yebhokisi
c) Gcina kwisitya esingangeni moya, uthintele ukudibana nomoya, ukuze ungonakali
Ukusetyenziswa kwe-VOC catalyst ngentsimbi ehloniphekileyo
I-VOC catalyst enentsimbi ehloniphekileyo isetyenziswa ngokubanzi kule mihlaba ilandelayo yemizi-mveliso: i-petrochemical, ikhemikhali, ukutshiza, ukuprinta, ukugquma, i-enameled wire, intsimbi yombala, ishishini lerabha, njl.
Phawula
- Kwinkqubo ye-catalytic combustion reaction, i-oksijini eyaneleyo kufuneka iqinisekiswe ukuba isabele ngee-VOCs.Xa i-oksijeni inganele, ukucocwa kwegesi yenkunkuma kuya kuchaphazeleka ngokuthe ngqo, okukhokelela kwikhabhoni emnyama kunye nezinye iimveliso ezifakwe kumphezulu we-catalyst, okubangela ukungasebenzi kwe-catalyst.
-Inkunkuma yegesi ayinakuqulatha isulfure, iphosphorus, iarsenic, ilothe, imercury, halogens (i-fluorine, iklorini, ibromine, iodine, i-astatine), isinyithi esinzima, i-resin, indawo yokubilisa ephezulu, iipolymers ezine-viscosity ephezulu kunye nezinye iikhemikhali eziyityhefu okanye izinto.
- I-catalyst kufuneka iphathwe ngobumnene, kwaye isalathiso somngxuma we-catalyst kufuneka sihambelane nesikhokelo sokuhamba komoya xa sigcwalisa, kwaye sibekwe ngokusondeleyo, ngaphandle kwezikhala.
-Ngaphambi kokungena kwi-VOCs igesi, kuyimfuneko ukungena emoyeni omtsha ohambayo ukuze uzalise ngokupheleleyo i-catalyst (preheat ukuya kwi-240 ℃ ~ 350 ℃, ibekwe ngokuhambelana nobushushu obuphezulu obufunwa yigesi enzima kakhulu kwi-exhaust gas component).
Ubushushu obuphezulu bokusebenza kwe-catalyst yi-250 ~ 500 ℃, i-exhaust concentration yi-500 ~ 4000mg / m3, kunye ne-GHSV yi-10000 ~ 20000h-1.Kufuneka kuphetshwe kangangoko kunokwenzeka ukunqanda ukonyuka ngesiquphe koxinzelelo lwegesi yokukhupha okanye ubushushu bexesha elide lobushushu obungaphezulu kwe-600℃.
- Ekupheleni komsebenzi, okokuqala unqumle umthombo wegesi ye-VOCs, sebenzisa umoya omtsha ukuze uqhubeke nokufudumeza imizuzu engama-20 kwaye emva koko uvale izixhobo zokutshisa i-catalytic.Ukunqanda i-catalyst ekudibaneni kweqondo eliphantsi kunye ne-VOCs gesi, kunokwandisa ngokufanelekileyo ubomi benkonzo ye-catalyst.
- Isiqulatho sothuli segesi yokukhupha igesi akufanele sibe ngaphezu kwe-10mg / m3, ngaphandle koko kulula ukubangela ukuvalelwa kweshaneli ye-catalyst.Ukuba kunzima ukunciphisa uthuli kwisimo esifanelekileyo ngaphambi kokuba unyango, kucetyiswa ukuba ususe rhoqo i-catalyst kwaye uyivuthele ngesibhamu somoya ngaphambi kokusetyenziswa, ngaphandle kokuyihlamba ngamanzi okanye nayiphi na i-liquid.
- Xa i-catalyst isetyenziselwa ixesha elide, kukho ukuncipha okuthile kumsebenzi, ibhedi ye-catalytic ingatshintshwa ngaphambi nangemva okanye phezulu naphantsi, okanye ukushisa okusebenzayo kwegumbi le-catalytic kunokunyuswa ngokufanelekileyo.
- Xa iqondo lokushisa lomlilo we-catalytic liphezulu kune-450 ℃, kuyacetyiswa ukuba uqalise i-fan yokupholisa eyongezelelweyo kwaye ugcwalise umoya obandayo ukupholisa isithando somlilo ukukhusela i-catalyst.
- I-catalyst kufuneka ikhuseleke ukufuma, musa ukucwina okanye ukuhlamba ngamanzi.
