I ngā pāmu huri noa i te ao, kei te puta he tukanga taiao i ia rā. Ka pirau ngā para rauropi—te paru kararehe, ngā toenga hua whenua, me ngā toenga kai—i te korenga o te hāora, ka puta he ranunga o ngā hau e mōhiotia ana ko te hau koiora. Ko tēnei hau koiora he mea tito mai i te methane (50–70%) me te hauhā waro, me te iti o te hauwai whanariki, te haukini, me te makuku. Ki te kore e whakahaerea, ka mawhiti te methane ki te āhuarangi, he hau kati kōtuhi kaha, neke atu i te 25 ngā wā ka kino ake i te hauhā waro i roto i te wā 100-tau. Engari ina hopukina, ka whakamahia, ka riro taua hau koiora hei puna pūngao whakahou: ka taea te tahu hei wera, te whakamahi i roto i te miihini whakaputa hiko, te whakapai ake rānei hei biomethane hei werohanga ki ngā whatunga hau taiao, hei wahie waka rānei.
He pātai whai hua te pātai mā ngā kaimahi pāmu, ngā kaiwhakawhanake pūngao taiwhenua, me ngā miihini taiao: ka taea e tepūwhakakoi diaphragm—he mīhini rongonui mō tōna parakore me tana mahi ā-pupuri—e whakahaere ana i te hau uaua, waikura, me te paru i ētahi wā e puta mai ana i te mīhini keri pāmu? Ko te whakautu, e tautokona ana e ngā tekau tau o te wheako me te hangarau whakaaro nui, he āe—me te whakarite me te whirihoranga tika.
Te Huarahi Biogas: Te Huri i te Para hei Taonga
Ko te hau koiora te tūāpapa o te ōhanga porowhita. I runga i te pāmu, ka kohia ngā para e tukuna ana te methane ki te rangi i roto i te mīhini keri anaerobic. Ka taea te whakamahi i te hau koiora e puta mai ana i te papaanga hei whakakapi i ngā wahie pūmua, hei whakaputa wera mō ngā whare witi, mō ngā whare kati kōtuhi rānei, hei whakahaere rānei i tētahi waeine wera me te hiko whakakotahi (CHP) hei whakaputa hiko me te pūngao wera. I muri i te purenga (te tango i te hauwai sulfide, te siloxanes, me te hauhā waro), ka huri te hau koiora hei biomethane—he whakakapinga mō te hau māori.
Heoi, kia whai hua ai te hau koiora i tua atu i te taha tata o te mīhini keri, me pēhi tonu. Ka puta te hau koiora mata i te pēhanga tata ki te hau. Hei penapena i roto i ngā tāke, hei kawe mā te wakatō, hei werohanga ki roto i te paipa, hei whakakī rānei i te tarakihana, i te taraka rānei, me pēhi te hau ki ngā pēhanga mai i te 10 pae ki te neke atu i te 250 pae. Koinei te wāhi e uru mai ai te pēhi diaphragm.
He aha te uaua o te hau koiora mō te pēhanga
I mua i te whakanui i te otinga, he mea nui kia mārama ki ngā wero e pā ana ki te hau koiora o te pāmu:
- Makuku: Ka kī te hau koiora mata i te mamaoa wai. Ina pēhia, ka taea e tēnei makuku te whakatōtō i roto i te pūwero, ka arahi ki te waikura, ki te raka waipēhi rānei.
- Hauwai whanariki (H₂S): Ka whakaekea e tēnei hau waikura te maha o ngā konganuku, inā koa i te aroaro o te wai. Ka taea e ia te whakangaro tere i ngā wāhanga pūhiko tuku iho.
- Ngā matūriki me ngā poke: Tērā pea he iti noa te puehu, ngā matūriki whanariki, tae atu ki ngā siloxanes (mai i ngā hua tiaki whaiaro).
- Te hanganga rerekē: Ka rerekē te hanganga o te hau koiora i runga i ngā rauemi kai, te pāmahana, me te hauora o te mīhini keri, me whai pūwero e taea ai te tu atu ki ētahi rerekētanga.
Ko te tikanga o ēnei āhuatanga, ka tere te pakaru o tētahi pūwero paerewa i hangaia mō te hau māori, te methane parakore rānei ina pāngia e te hau koiora pāmu kāore i te rongoatia. Heoi, he āhuatanga ā-roto tō te pūwero diaphragm, ā, ina honoa ki te maimoatanga tika i mua, ka tino pai te hononga.
Te Whakahaere a te Pūhiko Diaphragm i te Biogas
He maha ngā painga o te hoahoa hiri-ā-roto o te pūwero hiko o te diaphragm—e wehea ana te hau mai i te hinu waipēhi e te diaphragm whakarewa ngāwari—mō te mahi koiora:
Te ātete ki te waikura mā te whiriwhiri rauemi
Ka taea te hanga i ngā wāhanga kua mākūhia ki te hau (te pane, ngā takirere, te diaphragm) mai i te kowiri tira, i ētahi atu koranu ātete-waikura rānei, e ātete ana ki te whakaekenga a te hauwai whanariki me te makuku waikawa. E 40 tau o te tohungatanga rauemi, ka whiriwhiria e mātou te koranu tika mō tō hanganga hau.
Te pumau o te turuturu
Kei roto i te hau koiora te methane, he hau kati kōtuhi kaha, me ētahi atu wāhanga haunga kino, kino rānei. Kāore he turuturu o ngā pūngao hauhā, e ārai ana i ngā tukunga rere, ā, e whakarite ana kia noho tonu te pūngao hou ki roto i te pūnaha, kaua ki te āhuarangi.
Te ātete ki te makuku toenga
Ahakoa e tino taunaki ana mātou kia whakamarokehia te hau koiora i mua i te pēhitanga, he ngāwari ake te whakamahi i te pēhitanga diaphragm i ngā hangarau maha atu. Kāore he hiri mirimiri o te rūma hau ka pakaru pea i te makuku, ā, kua wehea te pūnaha waipēhi. Ka taea hoki e te whakamatao tika i waenga i ngā wāhanga te āwhina i te whakahaere i te hauhautanga.
Te āheinga pēhanga teitei
Ahakoa me whakakī e koe ngā rango hau mō ngā waka pāmu (200–250 pae), me werowero ki te whatunga ā-rohe, me penapena noa rānei te hau i te pēhanga ngawari (10–30 pae) mō te whakaputa hiko, ka taea te whirihora i ngā kōpeke diaphragm ki te tuku i te pēhanga tukunga e hiahiatia ana me te pono.
Te whakahaere i te poke
Mā te ara pēhi kore-hinu ka kore he hinu whakahinuhinu e uru ki te awa o te hau koiora. He mea nui tēnei mēnā ka whakamahia te hau koiora pēhi ki roto i te miihini hau (ka taea te poke i te hinu) ka whakapai ake rānei ki te biomethane mō te wahie waka.
Ngā Hipanga Whakaora i mua e Whai Hua ai
Kāore i te tūtohutia te whakahaere i tētahi pūwero diaphragm ki runga i te hau koiora mata o te pāmu me te kore e tukatukahia i mua. Ko tētahi pūnaha pono ko:
- Te tango makuku: Ka whakaitihia te ira tomairangi e te pouaka whakamatao, te mahanga waipūhau rānei, kia kore ai te wai wai e tae ki te pūwhakapūhau.
- Te horoinga hauwai whanariki: Mā te hautai rino, te tango whanariki koiora, te horoinga waikura rānei ka whakaiti i te H₂S ki ngā taumata e whakaaetia ana (i raro iho i te 200 ppm mō te nuinga o ngā koranu; he iti ake mō ngā taputapu tairongo o muri).
- Tātari matūriki: Ka hopukina e te tātari angiangi (1–5 micron) te puehu me ngā matūriki whanariki.
- Whakamaroketanga kōwhiringa: Mō ngā tono e hiahia ana ki te biomethane kounga paipa, ka whakaitihia te makuku e te whakamaroke maroke, e te whakamaroke kiriuhi rānei.
I muri i ēnei mahi, kua ma, kua maroke, ā, kua haumaru hoki te hau koiora mō te pēhi i te diaphragm. Ko te hua he pēhi pono, he pai hoki e mahi ana mō ngā tau maha me te iti o te tiaki.
He Tirohanga Ao Tūturu: Mai i te Parai ki te Nekenekehanga
Whakaarohia he pāmu miraka kau me ngā kau e 500. Ka kohia te paru kararehe ka whāngaihia ki roto i tētahi mīhini keri kore-hauora. Ko te hau koiora e puta ana—he nui hei whakakaha i tētahi kāinga iti—ka horoia tuatahitia i te H₂S me te wai. Kātahi ka whakanuia e te mīhini keri Xuzhou Huayan tōna pēhanga ki te 25 pae hei penapena i roto i tētahi tāke ārai tata. Mai i reira, ka whakakahangia e te hau koiora kua pēhia te waeine wera me te hiko e tuku hiko ana ki te pāmu me te wera mō te mīhini keri. Ko te biomethane kua pēhia te toenga, i muri i te whakapai ake, ka whakamahia hei whakakaha i tētahi kahui tarakihana pāmu kua hurihia hei whakahaere i runga i te hau. Ka noho motuhake te pāmu ki te pūngao, ka whakaitihia tōna tapuwae waro, ā, ka puta mai he moni whiwhi mai i te hau hou te nui.
Ehara tēnei i te pūtaiao pakiwaitara. Ko te ōhanga porowhita tēnei e mahi ana, e whakahohea ana e te hangarau kōpeketanga pakari.
He aha te Hiranga o te Wheako i roto i te Kōpeketanga o te Biogas
Ehara te hau koiora pāmu i te hau māori. Ko tōna waikura, te nui o te makuku, me te rerekētanga e hiahiatia ana he aromatawai hangarau e ahu mai ana i ngā tekau tau o ngā whakamahinga o te ao tūturu. Mā te whiriwhiri i ngā rauemi hē, te kore e tukatuka i mua, te whakaiti rānei i te ōwehenga pēhanga ka arahi pea ki te pakaru tere me te utu nui o te wā whakamutu.
