Inzuzo ye-VOC catalyst ngensimbi ehloniphekile
a) Uhlelo olubanzi lohlelo.I-VOC catalyst enensimbi ehlonishwayo isetshenziswa kabanzi, njengokufafaza, ukuphrinta, ipulasitiki eqinisiwe ye-fiber fiber, upende we-UV, imithi, amakhemikhali, i-petrochemical, izinhlelo zokusebenza zemboni yegesi yokukhipha igesi enamelled.Ukwakhiwa kwegesi engcolile embonini yokunyathelisa kulula, futhi izingxenye eziyinhloko zihlanganisa uchungechunge lwe-benzene, esters, alcohols, ketones nokunye.
b) Ukusebenza kahle kokwelashwa, akukho ukungcoliswa kwesibili.Izinga lokuhlanzwa kwegesi yemfucuza yemvelo elashwa ngendlela yokuvutha kwe-catalytic ngokuvamile lingaphezulu kuka-95%, futhi umkhiqizo wokugcina awunangozi i-CO2 ne-H2O, ngakho-ke ayikho inkinga yesibili yokungcola.Ngaphezu kwalokho, ngenxa yokushisa okuphansi, isizukulwane se-NOx singancishiswa kakhulu.
Ukuthumela, Iphakheji kanye nesitoreji
a) I-Xintan ingaletha i-VOC catalyst ngensimbi ehloniphekile engaphansi kuka-5000kgs phakathi kwezinsuku ezingu-7.
b) Ukupakisha: Ibhokisi lebhokisi
c) Gcina esitsheni esingangenisi umoya, vimbela ukuthintana nomoya, ukuze kungonakali
Izicelo ze-VOC catalyst ngensimbi ehloniphekile
I-VOC catalyst enensimbi ehlonishwayo isetshenziswa kabanzi emikhakheni yezimboni elandelayo: i-petrochemical, amakhemikhali, isifutho, ukuphrinta, ukunamathela, i-enameled wire, insimbi yombala, imboni yenjoloba, njll.
Phawula
- Enqubweni yokusabela kokuvutha kwe-catalytic, umoya-mpilo owanele kufanele uqinisekiswe ukuthi usabele nama-VOC.Uma i-oxygen inganele, ukusebenza kahle kokuhlanzwa kwegesi engcolile kuzothinteka ngokuqondile, okuholela ku-carbon black kanye neminye imikhiqizo enamathiselwe ebusweni be-catalyst, okuholela ekusebenzeni kwe-catalyst.
Igesi engcolile akufanele ibe nesibabule, i-phosphorus, i-arsenic, i-lead, i-mercury, i-halogens (i-fluorine, i-chlorine, i-bromine, i-iodine, i-astatine), izinsimbi ezisindayo, ama-resin, indawo ebilayo, ama-polymers ane-viscosity ephezulu nezinye izakhi zamakhemikhali ezinobuthi noma izinto.
- I-catalyst kufanele iphathwe ngobumnene, futhi isiqondiso somgodi we-catalyst kufanele sihambisane nesiqondiso sokugeleza komoya lapho sigcwalisa, futhi sibekwe eduze, ngaphandle kwezikhala.
-Ngaphambi kokufaka igesi ye-VOCs, kuyadingeka ukungena emoyeni omusha ogelezayo ukuze ushise ngokugcwele i-catalyst (preheat kuya ku-240 ℃ ~ 350 ℃, isethwe ngokuvumelana nezinga lokushisa eliphakeme kakhulu elidingwa igesi elinzima kakhulu engxenyeni yegesi yokukhipha).
Izinga lokushisa elilungile lokusebenza le-catalyst ngu-250~500℃, ukugxiliswa kwegesi ephumayo kungu-500~4000mg/m3, futhi i-GHSV ingu-10000~20000h-1.Kufanele kugwenywe ngangokunokwenzeka ukugwema ukwanda okungazelelwe kokugxilwa kwegesi yokukhipha umoya noma izinga lokushisa eliphakeme lesikhathi eside le-catalyst engaphezu kuka-600 ℃.
- Ekupheleni komsebenzi, okokuqala nqamula umthombo wegesi we-VOCs, sebenzisa umoya omusha ukuze uqhubeke ufudumeza imizuzu engu-20 bese uvala okokusebenza komlilo okuyi-catalytic.Ukugwema i-catalyst ekuthinteni kwezinga lokushisa eliphansi negesi ye-VOCs, kungandisa ngempumelelo impilo yesevisi ye-catalyst.
- Okuqukethwe kothuli lwegesi yokukhipha akufanele kudlule i-10mg / m3, ngaphandle kwalokho kulula ukubangela ukuvinjelwa kwesiteshi se-catalyst.Uma kunzima ukunciphisa uthuli esimweni esifanele ngaphambi kokwelashwa, kunconywa ukususa njalo i-catalyst futhi uyishaye ngesibhamu somoya ngaphambi kokusetshenziswa, ngaphandle kokuyigeza ngamanzi noma noma yiluphi uketshezi.
- Uma i-catalyst isetshenziswa isikhathi eside, kuba khona ukwehla okuthile emsebenzini, umbhede we-catalytic ungashintshwa ngaphambi nangemuva noma phezulu naphansi, noma izinga lokushisa lokusebenza kwegumbi le-catalytic lingakhuphuka ngokufanelekile.
- Uma izinga lokushisa lomlilo we-catalytic lingaphezu kuka-450 ℃, kunconywa ukuthi uqale isiphephetha-moya sokupholisa esingeziwe futhi ugcwalise umoya obandayo ukuze upholise isithando somlilo esikhuthazayo ukuze kuvikelwe i-catalyst.
- I-catalyst kufanele ivikele umswakama, ungacwilisi noma ugeze ngamanzi.
