Njengamanje, ubuchwepheshe obujwayelekile bokugcina i-hydrogen buhlanganisa isitoreji segesi esinengcindezi ephezulu, isitoreji se-cryogenic liquid, kanye nesitoreji sesimo esiqinile. Phakathi kwalokhu, isitoreji segesi esinengcindezi ephezulu sivele njengobuchwepheshe obuvuthiwe kakhulu ngenxa yezindleko zayo eziphansi, i-hydrogen refueling esheshayo, ukusetshenziswa kwamandla aphansi, kanye nesakhiwo esilula, okwenza kube ubuchwepheshe bokugcina i-hydrogen obukhethwayo.
Izinhlobo Ezine Zamathangi Esitoreji Se-Hydrogen:
Ngaphandle kwamathangi ayinhlanganisela avelayo ohlobo lwe-V agcwele ngaphandle kolayini bangaphakathi, izinhlobo ezine zamathangi okugcina i-hydrogen sezingenile emakethe:
1.Type I-all-metal tanks: Lawa amathangi anikeza umthamo omkhulu ezicindezelweni zokusebenza ezisukela ku-17.5 kuya ku-20 MPa, nezindleko eziphansi. Asetshenziswa ngenani elilinganiselwe ku-CNG (igesi yemvelo ecindezelwe) kanye namabhasi.
I-2.Type II amathangi ayinhlanganisela anemigqa yensimbi: Lawa amathangi ahlanganisa ama-metal liners (ngokuvamile insimbi) nezinto ezihlanganisiwe ezilimele endaweni eyihuphu. Banikeza umthamo omkhulu uma kuqhathaniswa nezingcindezi zokusebenza phakathi kuka-26 no-30 MPa, ngezindleko ezilinganiselwe. Zisetshenziswa kabanzi kuzicelo zezimoto ze-CNG.
3.Type III amathangi ayinhlanganisela yonke: Lawa amathangi afaka umthamo omncane ezicindezelweni zokusebenza phakathi kuka-30 no-70 MPa, anezinsimbi zensimbi (insimbi/i-aluminium) nezindleko eziphakeme. Bathola izinhlelo zokusebenza ezimotweni ezingasindi ze-hydrogen fuel cell.
I-4.I-Type IV yamathangi ayinhlanganisela enziwe ngepulasitiki: Lawa mathangi anikeza amandla amancane ezingcindezini zokusebenza eziphakathi kuka-30 no-70 MPa, anamalayini enziwe ngezinto ezifana ne-polyamide (PA6), i-high-density polyethylene (HDPE), namapulasitiki e-polyester (PET) .
Izinzuzo Zamathangi Okugcina I-Hydrogen Yohlobo IV:
Njengamanje, amathangi ohlobo lwe-IV asetshenziswa kabanzi ezimakethe zomhlaba, kanti amathangi ohlobo lwe-III asabusa imakethe yokugcina i-hydrogen.
Kwaziwa kahle ukuthi uma umfutho we-hydrogen udlula ama-MPa angama-30, ukufakwa kwe-hydrogen okungenakuguqulwa kungase kwenzeke, okuholela ekugqwaleni komugqa wensimbi futhi kubangele imifantu nokuphuka. Lesi simo singase siholele ekuvuzeni kwe-hydrogen nokuqhuma okulandelayo.
Ukwengeza, insimbi ye-aluminium kanye ne-carbon fibre ongqimbeni olumazombezombe inomehluko ongaba khona, okwenza ukuthintana okuqondile phakathi kwe-aluminium liner kanye ne-carbon fibre winding kube lula ukugqwala. Ukuvimbela lokhu, abacwaningi bengeze isendlalelo sokugqwala kokukhipha phakathi komugqa nongqimba olumazombezombe. Kodwa-ke, lokhu kwandisa isisindo sonke samathangi okugcina i-hydrogen, okwengeza ubunzima nezindleko.
Vikela Ukuthuthwa Kwe-Hydrojeni: Okubalulekile:
Uma kuqhathaniswa namathangi oHlobo lwe-III, amathangi okugcina e-hydrogen oHlobo lwe-IV anikeza izinzuzo ezibalulekile mayelana nokuphepha. Okokuqala, amathangi oHlobo lwe-IV asebenzisa amalayini angewona awensimbi akhiwe ngezinto eziyinhlanganisela ezifana ne-polyamide (PA6), i-high-density polyethylene (HDPE), kanye namapulasitiki e-polyester (PET). I-Polyamide (PA6) inikeza amandla aqinile okuqinile, ukumelana nomthelela, nezinga lokushisa elincibilikayo eliphezulu (elifika ku-220℃). I-High-density polyethylene (HDPE) ikhombisa ukumelana nokushisa okuhle kakhulu, ukumelana nokuqhekeka kwengcindezi yemvelo, ukuqina, kanye nokumelana nomthelela. Ngokuqiniswa kwalezi zinto eziyinhlanganisela yepulasitiki, amathangi oHlobo lwe-IV akhombisa ukumelana nokugqwala kwe-hydrogen nokugqwala, okuholela ekuphileni kwesevisi okwandisiwe nokuphepha okuthuthukisiwe. Okwesibili, imvelo engasindi yezinto ezihlanganisiwe zepulasitiki inciphisa isisindo samathangi, okuholela ezindlekweni eziphansi zokusebenza.
Isiphetho:
Ukuhlanganiswa kwezinto eziyinhlanganisela emathangini okugcina e-hydrogen oHlobo lwe-IV kumelela intuthuko enkulu ekuthuthukiseni ukuphepha nokusebenza. Ukwamukelwa kwama-non-metallic liners, njenge-polyamide (PA6), i-polyethylene ephezulu kakhulu (i-HDPE), namapulasitiki e-polyester (PET), kunikeza ukumelana okuthuthukisiwe ekugxilweni kwe-hydrogen nokugqwala. Ngaphezu kwalokho, izici ezingasindi zalezi zinto eziyinhlanganisela yepulasitiki zifaka isandla ekwehliseni isisindo kanye nezindleko eziphansi zokuhlela. Njengoba amathangi oHlobo lwe-IV esetshenziswa kabanzi ezimakethe futhi amathangi oHlobo lwe-III ehlala ebusa, ukuthuthukiswa okuqhubekayo kobuchwepheshe bokugcina i-hydrogen kubalulekile ukuze kuqashwe amandla aphelele e-hydrogen njengomthombo wamandla ahlanzekile.
