Umbhikiso Wesiqephu Esishiyekileyo (VSA): Izinhlelo Zokuhlinza Amagama Emfulweni Ekhethwe Yezilimo

Zonke Izigaba

umsebenzi wokusukela ngephakamiso lokuhlola ngokulandelana nokhoza olungaphandle

U-Vacuum Swing Adsorption (VSA) ukuchasazela umthombo omphakathi wokusetyenziswa kokukhula okulandelayo kwezintathu ezinethemba zokusebenza ngokwesikleli sokutsibatsa nokubheka. Lomthebhu olunokuqaleni lusetshenziswa amanye amagama-zeolite asebenzisa amaxwebhu weziNtamu amakhulu esetshenziswa ukubheka komhlaba, lokuhlala ukubheka iziNtamu ngezinye izinto zezinhlangano ezifanayo. Ukuphumelela kufanele ukuthi iingxenye eziningi zisebenzise ngokushesha, ngokuba ingxenye elikhulu lokusebenza ngokushesha loluhlelo lokusebenza ngokushesha, futhi lezi zihlala ngaphandle kokuthi bengakho ukubheka. Ngendawo yokubhekana, ikhuthazelo lokusebenza ngokushesha kufanele ukuthi isebenza ngokushesha lokusebenza ngokushesha, futhi lezi zihlala ngaphandle kokuthi bengakho ukubheka. Ukuphumelela kufanele ukuthi iingxenye eziningi zisebenzise ngokushesha, ngokuba ingxenye elikhulu lokusebenza ngokushesha loluhlelo lokusebenza ngokushesha, futhi lezi zihlala ngaphandle kokuthi bengakho ukubheka. Ukuphumelela kufanele ukuthi iingxenye eziningi zisebenzise ngokushesha, ngokuba ingxenye elikhulu lokusebenza ngokushesha loluhlelo lokusebenza ngokushesha, futhi lezi zihlala ngaphandle kokuthi bengakho ukubheka. Umthombo wokuhula waseVSA usetyenziswa ngokubanzi kakhulu ngokusebenzisa amaxesha amakhulu, ukuhlola okungabafani, nokuthi amaxesha amakhulu akhona amahlelo angaphansi.

Izincomo Zomkhiqizo Omusha

Inqubo ye-Vacuum Swing Adsorption inikeza izinzuzo eziningi ezicindezelayo ezenza kube ukukhetha okuhle kakhulu kokukhiqizwa komoya-mpilo ezimbonini ezihlukahlukene. Okokuqala nokubaluleke kakhulu, izinhlelo ze-VSA zinikeza ukusebenza kahle kwezindleko ezihlukile ekukhiqizeni i-oxygen uma kuqhathaniswa nezindlela zendabuko zokunikeza i-oxygen ewuketshezi. Ngokukhiqiza umoya-mpilo endaweni, izinhlangano zingaqeda izindleko eziqhubekayo ezihlobene nokuthengwa komoya-mpilo omningi, izindleko zokuhamba, nokuqashwa kwamathangi okugcina. Ukusebenza kahle kobuchwepheshe be-VSA kuholela ekusetshenzisweni kwamandla aphansi ngeyunithi ngayinye yomoya-mpilo ekhiqizwayo, okuholela ezindlekweni ezincishisiwe zezinsiza kanye ne-carbon footprint encane. Enye inzuzo ebalulekile ukuthembeka nokuzimela kohlelo. Lapho sezifakelwe, izitshalo ze-VSA zisebenza ngokuqhubekayo ngaphandle kokungenela komuntu, zidinga kuphela ukuhlolwa kokugcinwa okuvamile. Ukuqedwa kokuxhomeka kubahlinzeki bangaphandle be-oksijini kuqinisekisa ukutholakala okungaphazanyiswa, okubaluleke kakhulu ezikhungweni ezisezindaweni ezikude noma lezo ezidinga ukuphakelwa kwe-oksijini njalo. Ukuphepha kungenye inzuzo enkulu, njengoba izinhlelo ze-VSA zisusa izingozi ezihlobene nokuphathwa nokugcinwa komoya-mpilo onamanzi. Le nqubo isebenza ngaphansi kwengcindezi eseduze nomoya, inciphise amathuba ezingozi futhi yenze lula izinqubo zokuphepha. Ngaphezu kwalokho, izinhlelo zanamuhla ze-VSA zinezinhlelo ezithuthukile zokuqapha nokulawula, ezivumela ukwenziwa kahle kokusebenza ngesikhathi sangempela nokugcinwa kokubikezela. Ukwehluka kobuchwepheshe be-VSA kwenza izakhiwo zikwazi ukufanisa ukukhiqizwa komoya-mpilo nezidingo zazo, kugwenywe imfucuza nokungasebenzi kahle. Ubukhulu besistimu buyenza ilungele ukufakwa lapho isikhala sinqunyelwe khona, kuyilapho ukwakheka kwayo okuyi-modular kuvumela ukwanda kwamandla esikhathini esizayo ngokuphazanyiswa okuncane kokusebenza okukhona.

umsebenzi wokusukela ngephakamiso lokuhlola ngokulandelana nokhoza olungaphandle

Udlulintlelo Lomoya Namasiphemphe Osikhatsi

Udlulintlelo Lomoya Namasiphemphe Osikhatsi

Umlinganisi wokuqasha lweVSA uhluke kakhulu ngokuthi uyihlobene nesibonelo sasemva kakhulukazi, okungakhothenjwa ngaphandle kokuba amalume akhethwe umsebenzi. Ngokushesha, izindlela ezidinga ukusondziswa kwesiqephu esincane nokuhlola kuhlonipheka iimoya zisetyenziswa imoya yezilimi ezinamandla ngokubona ukuthi zisetyenziswa isiqephu sokuphucuka nokuhlola, VSA usetyenziswa ngendawo yokugcina emanzini nokuhlola ngamagunya engaphezulu. Isistimu sisetshenziswa amanye amaxesha amazinye wezinto eziphathelayo nokutsiphindaphinda amagunya amandla ukusetyenziswa kuhluke kakhulu ngokuthi ikhombisa umoya omphambili. Ukusenzeniso lokuhluke kakhulukazi kukhangelela amafula aokushesha ngokuthi abangabangeni 30-40% ngokushesha kakhulu phakathi komsebenzi wesintu esikhoyo lokusebenza umoya. Imininingwane yesikhathi yokusetyenziswa kuhluke kakhulukazi ngokushesha kakhulu ngokuthi kumgangatho lokusebenza ngokuphihlwe kuhluke kakhulukazi ngokushesha kakhulu, okungakhothenjwa ngaphandle kokuba amalume akhethwe umsebenzi. Ngakho ke, ukuhlukaniswa kwezinto ezisetshenziswa ngokubhekisisa umsebenzi ngokwesicwangciso sesicwangciso sikuhluke kakhulukazi ngokuthi amalume asetyenziswa ngaphandle kokuba kuhlanganise umoya owesicwangciso esincinci, ukufuneka lokuncacisa umsebenzi wokusetshenziswa.
Ukusebenzisa Ngokuphambili Nangokugcina Ukuvavanya

Ukusebenzisa Ngokuphambili Nangokugcina Ukuvavanya

Yindawo eyaphakamisi kakhulu lokuthi ngalokho olungileyo lweVSA kulungiselelwa ngokuphambili kunye nesiphumo esijulileyo sokuvavanya. Isistimu sikhetha amagama amacabango emphakathini okulandelayo ezivamisela nokufinyelela iziphumo zokusebenza ukuthi zikohlwe ngokukhangelwe. Lolu hlobo lokuhlola kuhlanganiswa ngokuthi amacompomponyenti angqinisekise ahlola ukuthi azizange zihlale kudala, uzoba kusenzo esidingayo kuzofika kwezinye izinsuku zokusebenza nokuthi zingasusa ukuvavanya. Izinsuku ezinsebenzi zokusebenza zimanywa ngokubhekisisa amatshepa omphakathi kunye nezinsiza zokubheka eziphumulekileyo, okuningi lokhu lakuqhathanisela nokuba lavela ngokwesigaba esiqhathaniswayo kunye nokusebenzela ngabantu abasebenzela isifundo. Ikhathelo leselfendi lokusebenza lisusela amaphrofesheni ukuthi bafundise abantu babekho babekhona ngaphandle kokuthi bazingene zikhono, ubungena ukusetshenziswa nokuthi akudingekho idatha engaphansi.
Ukugcina kwezilungiselelo nokuhlinzekela okubonakali

Ukugcina kwezilungiselelo nokuhlinzekela okubonakali

Iphrogesi ye-VSA iyiphindaphinda ngokwesiphi ngokuthi ukufakwa komkhakha kunye neziqondiso zokuhlinzekela ezifanekayo. Ukusetyenziswa okumnguni wakuhlola ukwenza imibono yokuvamisa ukuze ikhuse lezo zinto ezithunyelwe kwisekhono kunye nemibuzo yezimpahla, lokuna kufanele ukuba kube ngenxa yezikhwembu ezintsha kunye nokusetshenziswa kwabanye abahlali. Ukuphumelela kakhulu kwezindlela ezikhona icima isigaba somkhakha sokugcina umoya, futhi ukwazi wokuhlala ngokukhawuleza ngakwesinye sijimi sesobizo esizidinga ukukhetha amasayensi efanekayo. Ukusetyenziswa okuhlinzekelayo lwe-VSA iyeza izikhundla zeziphumo ukuya emva kokuthi imfihlakalo yakho ibaleke uphawu oluncinci lokulula ukuthi uzame ukuyibuyekeza ngokuphelele ngakwesikhatsi esingaduma, uzame ukususa imali engaphezulu yezinto ezincedwe ngokwahlula. Leli phindaphindi leliqondo lokufakwa komkhakha ifanele ukuba libuyekeze ngokushesha kakhulu kwiqhaza lokusebenza lokhu kunesiqephepha esisodwa kunye nokuba kusenziwe kakhulu ngokubhekisisa lesayithi ngokwesikhatsi sekuphela ngokuthi kuneziqephepha ezishesha zokusetyenziswa ngemvume kobunye obudala.
