Icala Lokuqhekeka Kwesimo Sokusebenza Eliyinselele — Uhlelo Lokubuyisela Izinsalela ze-PTA (R2R)
Ekukhiqizweni kwe-Purified Terephthalic Acid (PTA), i-Residue Recovery System (R2R) idlala indima ebalulekile ekukhiqizeni okuluhlaza kanye nokuvuselelwa kwezinsiza. Ngokusebenzisa i-pyrolysis yokushisa okuphezulu endaweni engenawo umoya-mpilo, izinsalela zezinto eziphilayo ezikhiqizwa ngesikhathi senqubo ye-PTA ziyaqhekeka ngokushisa: ama-molecule amakhulu ezinto eziphilayo aguqulwa abe amagesi avuthayo kanye namafutha acebile nge-benzoic-acid, kuyilapho ama-catalyst e-cobalt ne-manganese ayigugu egxile esigabeni somlotha. Lawa ma-catalyst abese etholakala ngokugezwa kwe-alkaline, ukuncibilikiswa, ukuhlunga, kanye nokucwengwa, kwakha izixazululo ze-catalyst ezivuselelwe ezibuyela enkambisweni yokusabela eyinhloko.
Lolu hlelo lonke oluvaliwe luguqula imfucuza eyingozi ibe yimithombo ebalulekile—okwenza iyunithi ye-R2R ingabi “umzila” wemvelo wesitshalo se-PTA kuphela, kodwa futhi ibe ngumshayeli oyinhloko wokunciphisa izindleko kanye nokuncintisana.
Iqiniso Elinzima Lezimo Zokusebenza ze-R2R
Ngenxa yendima yayo ebalulekile kanye nokwakheka kwayo okuyinkimbinkimbi kakhulu kwemidiya, iyunithi ye-R2R ingenye yezingxenye ezinzima kakhulu esitshalweni sonke. Ibeka izinselele ezinkulu kuyo yonke imishini ebalulekile, ikakhulukazi ama-valve:
- Ukwakheka Kwekristalu Nokupheka
Izinsalela ze-PTA ziqina kalula noma zijike uma amazinga okushisa eshintshashintsha, okuholela ekunamatheleni kwe-valve, ukunyakaza okubi, kanye nokulawula okungazinzile. - Ukugqwala Okukhulu Nokuguguleka Kwendawo
Le ndlela yokuxhumana iqukethe ama-bromide, ama-organic acid, kanye nomlotha oqinile we-catalyst. Lokhu kubangela ukugqwala okukhulu kwamakhemikhali kanye nokuguguleka kwemishini, kubhubhise ngokushesha izindawo zokuvala. - Izinga Lokushisa Eliphezulu kanye nokucindezeleka kokujikeleza kwe-Thermal
Kuqhubeke Izinga Lokushisa Eliphezulus kusheshisa ukukhukhuleka nokuguga kwezinto, kuyilapho imijikelezo yokushisa ephindaphindwayo ibangela ukuqhekeka kokucindezeleka.
Lezi zinkinga ezintathu ziyahlangana futhi ziyakhulisana, okwenza ama-valve abe yisixhumanisi esibuthakathaka esivimbela ukusebenza kwe-R2R okuzinzile nomjikelezo omude.
Izixazululo Zendabuko Zifika Enkingeni
Amavalvu e-titaniumimelana nokugqwala kodwa ayikwazi ukumelana nokuguguleka kwesivinini esikhulu.
Amavalvu ambozwe nge-Stellitezinikeza ukusebenza okulinganiselayo kodwa zihlushwa ukuqhekeka noma ukuqhekeka kwendwangu okungenakugwenywa.
Le mikhawulo yashukumisela imboni ukuthi ifune ikhambi elihluke ngokuphelele.
Ukuphumelela: KOWOV Amavalvu e-Ceramic
I-KOWOV's ithuthukile Amavalvu e-Ceramic ukubhekana ngqo namaphuzu ayinhloko obuhlungu bezinhlelo zokusebenza ze-R2R.
Ukusebenza Okungalingani Kwezinto Ezibalulekile
- Ubulukhuni be-ceramic budlula UMDLALO 90, okungaphezu kakhulu kwezinsimbi zensimbi zendabuko, okumelana kalula nokuguguleka okukhulu kwezinhlayiya.
- Ukungasebenzi kahle kwamakhemikhali kunikeza ukumelana okuvelele kuma-bromides, ama-organic acid, kanye nezinye izinto ezihlaselayo.
- Izindawo zobumba ezibushelelezi njengezibuko zinciphisa kakhulu ukunamathela, zinciphisa ukugoba kanye nokwakheka.
Imiphumela Emisebenzini Yangempela ye-PTA R2R
Ngesikhathi sokusebenza okuqhubekayo kwezimboni, i-KOWOV Amavalvu e-Ceramic inikeze ukusebenza okumangalisayo:
- Impilo yesevisi ithuthukiswe ngo-5–8×uma kuqhathaniswa nama-valve ensimbi
- Izinkinga zokunamathela nokupheka ama-valve cishe ziqediwe
- Ukuvuza kwangaphakathi kuncishiswe kakhulu, okuqinisekisa ukulawulwa kwenqubo okuzinzile
- Ukuhlanzeka kwe-catalyst kuthuthukisiwe ngenxa yokuncipha kokuguguleka kwama-valve
- Ukuvalwa okungahleliwe kwehle kakhulu, kwandisa isikhathi sokusebenza esiqhubekayo
Umphumela Wecala — Iphrojekthi Enkulu Ye-PTA
Ngemva kokushintsha ngokuphelele amavalvu endabuko nge-KOWOV Amavalvu e-Ceramic Ezikhundleni ezibalulekile ze-R2R, isitshalo esisodwa esikhulu se-PTA safeza:
- Ukwehliswa okungu-70% kwezindleko zokulungisa
- Umjikelezo wokushintsha amavalvu unwetshwa kusukela ezinyangeni ezi-3 kuya ezinyangeni eziyi-18+
- Ukwanda okungu-15% kwesilinganiso sokusebenza okuqhubekayo
- Ukususwa kokuguquguquka kwenqubo okubangelwa ukuvuza kwe-valve
- Ukuthobela imithetho yemvelo okuthuthukisiwe kanye nokuphepha kokusebenza
Isiphetho
Ukusetshenziswa ngempumelelo kwama-valve e-KOWOV ceramic ezinhlelweni ze-R2R kumelela intuthuko enkulu kwezobuchwepheshe embonini ye-PTA. Akugcini nje ngokunqoba izithiyo zobuchwepheshe ezinde kodwa futhi kunikeza ukwesekwa okuqinile ekuphishekeleni kwemboni ukusebenza kahle okuphezulu, ukukhishwa okuphansi komoya, kanye nezindleko zokusebenza ezincishisiwe.
Njengoba isayensi yezinto ezibonakalayo kanye nobuchwepheshe bokukhiqiza buqhubeka nokuthuthuka, ama-valve e-ceramic azodlala indima ebaluleke kakhulu kuzo zonke izinqubo zamakhemikhali eziyinkimbinkimbi. I-KOWOV iyaziqhenya ngokuhola lolu shintsho—ukubeka indinganiso entsha yemboni yokuthembeka nokusebenza ezinhlelweni zama-valve e-R2R.
