Okwangoku, ezona teknoloji ziqhelekileyo zokugcina i-hydrogen ziquka ukugcinwa kwegesi ephezulu yoxinzelelo, ukugcinwa kolwelo lwe-cryogenic, kunye nokugcinwa kombuso oqinileyo. Phakathi kwezi, ukugcinwa kwegesi ephezulu yoxinzelelo kuye kwavela njengeyona teknoloji ikhulileyo ngenxa yeendleko zayo eziphantsi, i-hydrogen refueling ngokukhawuleza, ukusetyenziswa kwamandla aphantsi, kunye nesakhiwo esilula, okwenza kube yiteknoloji yokugcina i-hydrogen ekhethiweyo.
Iindidi ezine zeeTanki zoGcino lweHydrojeni:
Ngaphandle kweitanki ezigcweleyo zodidi lwe-V oluvelayo ngaphandle kweelitha zangaphakathi, iintlobo ezine zeetanki zokugcina i-hydrogen zingenile kwimarike:
I-1.I-Type I yonke iitanki zetsimbi: Ezi tanki zinika amandla amakhulu kwiingcinezelo zokusebenza ukusuka kwi-17.5 ukuya kwi-20 MPa, kunye neendleko eziphantsi. Zisetyenziselwa ubungakanani obulinganiselweyo kwi-CNG (igesi yendalo ecinezelweyo) iilori kunye neebhasi.
I-2.I-Type II iitanki ezidibeneyo ezixutywe ngetsimbi: Ezi tanki zidibanisa iileyili zetsimbi (ngokuqhelekileyo intsimbi) kunye nezinto ezidibeneyo ezinxeba kwi-hoop direction. Banikezela ngomthamo omkhulu kwiingcinezelo zokusebenza phakathi kwe-26 kunye ne-30 MPa, kunye neendleko eziphakathi. Zisetyenziswa ngokubanzi kwizicelo zezithuthi ze-CNG.
I-3.Udidi lwe-III iitanki zonke ezidibeneyo: Ezi tanki zibonisa umthamo omncinci kwiingcinezelo zokusebenza phakathi kwe-30 kunye ne-70 MPa, kunye ne-metal liners (intsimbi / i-aluminium) kunye neendleko eziphezulu. Bafumana usetyenziso kwiimoto zeeseli ze-hydrogen ezikhaphukhaphu.
I-4.I-IV ye-IV ye-plastic-lined composite tanks: Ezi tanki zinika umthamo omncinci kwiingcinezelo zokusebenza phakathi kwe-30 kunye ne-70 MPa, kunye neentambo ezenziwe ngezinto ezifana ne-polyamide (PA6), i-polyethylene ephezulu (i-HDPE), kunye neeplastiki ze-polyester (PET) .
Izinto eziluncedo zoHlobo lwe-IV lweeTanki zoGcino lweHydrojeni:
Okwangoku, iitanki zoHlobo lwe-IV zisetyenziswa ngokubanzi kwiimarike zehlabathi, ngelixa iitanki zohlobo lwe-III zisalawula imarike yokugcina i-hydrogen.
Kuyaziwa ukuba xa uxinzelelo lwe-hydrogen lungaphezu kwe-30 MPa, i-hydrogen embrittlement engenakuguqulwa inokuthi yenzeke, ekhokelela ekudakaleni kwe-liner yentsimbi kwaye ibangele ukuqhekeka kunye nokuqhekeka. Le meko inokukhokelela ekuvuzeni kwe-hydrogen kunye nokudubula okulandelayo.
Ukongeza, i-aluminiyam yesinyithi kunye ne-carbon fiber kwi-maleko ejikelezayo inomahluko onokuthi ube khona, okwenza uqhagamshelwano oluthe ngqo phakathi kwe-aluminium liner kunye ne-carbon fiber winding esengozini yokubola. Ukuthintela oku, abaphandi bongeze i-corrosion layer yokukhupha phakathi kwe-liner kunye ne-winging layer. Nangona kunjalo, oku kwandisa ubunzima obupheleleyo beetanki zokugcina i-hydrogen, yongeza ubunzima kunye neendleko.
Khusela uThutho lweHydrojeni: Okuphambili:
Xa kuthelekiswa nohlobo lweetanki ze-III, Iitanki zokugcina i-hydrogen ze-IV zibonelela ngeenzuzo ezibalulekileyo malunga nokhuseleko. Okokuqala, iitanki zoHlobo lwe-IV zisebenzisa iintambo ezingezizo ezentsimbi ezenziwe ngezinto ezidityanisiweyo ezifana ne-polyamide (PA6), i-high-density polyethylene (HDPE), kunye neeplastiki zepolyester (PET). I-Polyamide (PA6) inika amandla abalaseleyo okuqina, ukuxhathisa impembelelo, kunye nobushushu obuphezulu bokunyibilika (ukuya kuthi ga kwi-220℃). I-high-density polyethylene (HDPE) ibonisa ukumelana nobushushu obugqwesileyo, ukunganyangeki koxinzelelo lwendalo esingqongileyo, ukuqina, kunye nokumelana nefuthe. Ngokuqiniswa kwezi zixhobo zeplastiki ezidibeneyo, iitanki zohlobo lwe-IV zibonisa ukuchasana okuphezulu kwi-hydrogen embrittlement kunye ne-corrosion, ekhokelela kubomi benkonzo eyandisiweyo kunye nokhuseleko olwandisiweyo. Okwesibini, ubume obukhaphukhaphu bezinto ezihlanganisiweyo zeplastiki kunciphisa ubunzima beetanki, okubangela iindleko eziphantsi zolungiselelo.
Isiphelo:
Ukuhlanganiswa kwezinto ezidibeneyo kwiitanki zokugcina i-hydrogen IV kubonisa ukuqhubela phambili okubalulekileyo ekuphuculeni ukhuseleko kunye nokusebenza. Ukwamkelwa kwee-liners ezingezona zensimbi, ezifana ne-polyamide (PA6), i-polyethylene ephezulu (i-HDPE), kunye neeplastiki ze-polyester (i-PET), inikezela ukuchasana okuphuculweyo kwi-hydrogen embrittlement kunye ne-corrosion. Ngaphezu koko, iimpawu ezikhaphukhaphu zezi zixhobo zeplastiki ezidibeneyo zinegalelo ekunciphiseni ubunzima kunye neendleko eziphantsi zolungiselelo. Njengoko iitanki zoHlobo lwe-IV zifumana ukusetyenziswa ngokubanzi kwiimarike kunye neetanki zoHlobo lwe-III zihlala zilawula, uphuhliso oluqhubekayo lokugcinwa kwe-hydrogen technologies lubalulekile ekuqondeni amandla apheleleyo e-hydrogen njengomthombo wamandla ococekileyo.
