He pēhea te mahi a te whare hanga uku, ā, he pēhea tonu te noho pai ki te taiao?
Kua Whakaaro Ake Nei Koe He Aha Ngā Mea Ka Tupu I Muri I Te Puranga?
I ia wā e haereere ana koe i te huarahi hou kua whakakikoruatia, kei te taraiwa koe i runga i tētahi wheketere matū iti i ngunguru i te 180 °C i mua. Engari me pēhea te mahi a tētahi wheketere uku, ā, he aha me aro nui ai ngā kaimahi kirimana, ngā kaipupuri moni, tae atu ki ngā tāngata e aro nui ana ki te taiao? Noho mai—kia tae ki te mutunga o tēnei pānui poto ka taea e koe te hikoi ki tētahi papa mahi me te kōrero me te mea nōu te wāhi.
Te Rerenga Mahi Matua: Mai i te Whakakotahi ki te Ranunga Wera
I te ngako o te pūnaha uku, he hononga tika o te wera, te matū, me te ahupūngao ā-pūkaha te tipu uku. He rite tonu te raupapatanga:
- Ka tukuna e ngā ipu whāngai matao ngā mea whakahiato (kōhatu, onepu, RAP) ki runga i te kaikawe whitiki i ngā ōwehenga kua whakaritea.
- Ka tōia e te mata whakairo maha-papa te toka nunui rawa atu i te au—āe, "haere atu" te kī a ngā kaihanga rakau—i mua i te pānga o te pahu.
- Ka whakanuia e te whakamaroke hurihuri te pāmahana o te matū ki te ±160 °C, i te mea ka roa ake te mura o te mura i te pahi kura.
- Ka hiki ake te rauemi maroke e te ararewa wera ki te tihi o te pourewa ka taka ki roto i ngā papa ārai me ngā ipu wera.
- Ka papua te uku mai i ngā tāke kua whakamahanatia, ka werohia mā roto i tētahi pae rehu; ka inehia te whakakī (koima, sima) hei whakatikatika i te matotoru.
- E ono hēkona noa iho te roa o te whakaranu a te mira pugmill, te mīhini whakaranu poro-rua rānei—he mea nui te wā nā te mea ka tere te whakapakeke o te uku.
- Ka rongoatia te ranunga wera kua oti ki roto i ngā silo utaina kia tae mai rā anō ngā taraka, mā tēnei ka noho tonu te mahi a te wheketere i te āhua pumau, kaua i te āhua mutu-tīmata.
Kei te neke mai i te puranga ki te haere tonu? Kaua e manukanuka. Ka whakapikohia e ngā tipu ranunga-pahu ngā taahiraa 3-6 ki roto i te pahu roa kotahi, ka whakawhiti i te mana tunu tika mō te putanga 20% teitei ake i te tana-ia-haora.
Ngā Wāhanga Matua Kāore i Kōrerohia e te Tangata
1. Kara RAP
Kāore te papa uku kua whakahokia mai (RAP) e ringihia noa ki roto; ka uru atu mā roto i te kōhao waenga-pū, ka puta te makuku mai i te kirikiri kua wera kē ki te 180 °C, engari kāore e tahuna te uku tawhito. Ki te wera rawa, ka puta he paoa kikorangi; ki te mātao rawa, ka puta he paru piri, kāore e piri.
2. Whare Pēke me te Hopu Tuarua
I muri i te putanga o te hau putanga mai i te pū, ka mau te whare putea pulse-jet i ngā matūriki tae noa ki te 1 micron. Ka werohia e ngā tipu o ēnei rā te waro whakahohe, te paru raima rānei hei whao i ngā hydrocarbons aromatic polycyclic (PAH). Ko te hua whakamutunga: ko te opacity o te puranga kei raro iho i te 10%, he pai ake i te nuinga o ngā auahi tunu kawhe.
3. Taupoki Wera Utaina-Tuku
Kua kite koe i te āhua o te kanapa ngoikore o ētahi whare pupuri taonga i te pō? Ka hurihia e te hipoki te wera o te puranga kua hopukina ki te kōne whare pupuri taonga, hei ārai i ngā "wāhi wera" e whakapūkara ana i te bitumen ka huri i tō ranunga utu nui hei pōporo pakarukaru.
Te Whakakore i ngā Pūrākau Taiao
"He taniwha pupuhi auahi ngā tipu uku." Nō te tekau tau atu i 1970 tēnā kōrero. Mai i te wā i noho ai te whakamātautau EPA Method 9 hei paerewa, kua heke te toharite o ngā tukunga mō ia tana o te ranunga mā te 97%. Ka tāpirihia ngā mura iti-NOx, ngā puku auau-rerekē i runga i ia motuka, me ngā tāpiringa ranunga mahana e whakaiti ana i te pāmahana whakaputa ki te 135 °C. Ko te tino take: he iti ake te whakaputanga e koe i te whakahaere i tētahi tipu 200-tana/haora i tō tō matua keke i te whakahaere i tētahi papa uku kotahi.
Te Whakamamati me te Tiaki Matapae
Ka aro turukihia e ngā pūoko e hono ana ki te kapua te kume o te whitiki, te wiri o te peera, me te whakakoi i te mura o te mura. Ka tohu ngā tauira ako-mīhini i ngā āhuatanga rerekē i mua i te whati o te whitiki whāngai matao i te 2 i te ata—whakapono mai, kāore he tangata e hiahia ana ki te hanga hononga mā te rama. I roto i te roanga o te oranga o te tipu mō ngā tau 25, ka taea e ngā tātaritanga matapae te penapena tae atu ki te US $1.2 miriona i roto i te wā whakatā kore i whakaritea.
Tauira ROI o te Ao Tūturu
I huri tētahi kaunihera o Midwestern mai i te ranunga parakore 100% ki te ranunga RAP 40%. Te utu tīmatanga: US $180,000 mō te kara RAP hou me te mata. Te utu whakahoki: 14 marama nā te penapena ā-tau US $110,000 mō te parakore me te uku. He tāpiri: kua piki ake te pakeketanga o te rori mā te 8%, nā te mea ko te uku kua pakeketia ka whakapakeke i te mastic. Kāore i te kino mō ngā "para" i kīia e ngā pepa tawhito kia ruia ki te whenua.
Ngā Hiccups Noa me ngā Whakatika Tere
- Te makuku i te RAP: Taupokina te teitei o te puranga ki te 3 m, taupokina ki ngā tārapi, ka utaina ki mua te tuatahi ki roto, tuatahi ki waho.
- Auahi kikorangi: Whakaitihia te pāmahana whakauru o te pahu mā te 10 °C, ā, tirohia te ōwehenga hau-ki-wahie o te mura; he nui rawa te pāmahana i te nuinga o te wā.
- Te wehewehenga i roto i te silo: Tāutahia he whakaurunga konukōre rere-papatipu; he $5 mano tāra te utu, ka penapena i te 50 tana o te ranunga para i ia marama.
Ngā Auahatanga o te Ao hei Mātaki
Kei te whakamātautau ngā OEM o ngā tipu i ngā tahu hauwai me ngā ranunga RAP 60% mā te whakamahi i ngā mea whakaora koiora i ahu mai i te kapia paina. Mēnā ka noho tonu ngā whiwhinga waro ki runga ake i te US $70 mō ia tana, e matapaetia ana ka whiwhi ngā kaiwhakahou tuatahi i ngā whakahoutanga i roto i ngā tau e whā. I taua wā, kei te heke iho ngā kete pahuka ranunga mahana e whakahou ana ki tētahi tipu o nāianei i raro iho i te US $30 mano, ko te tikanga ka taea e ngā kaihanga papa iti te tono mō ngā kirimana "huarahi matomato" i rāhuitia mō ngā tama nunui.
