He maha ngā taputapu tukatuka nui o ngā whare hangarua PET e honoa ana e ngā pūnaha kawe hau me ngā pūnaha kawe miihini. Kāore e tika kia puta he wā whakamutu nā te hoahoa pūnaha tuku kino, te whakamahinga hē o ngā wāhanga, te kore rānei o te tiaki. Pātai atu mō ētahi atu. #Ngā Tikanga Pai
E whakaae ana te katoa he mea pai te whakaputa hua mai i te PET hangarua (rPET), engari ehara i te mea ngāwari te whakaputa wāhanga kounga teitei mai i ngā rauemi mata matapōkere, pērā i ngā pounamu PET i muri i te kaihoko. Ko ngā taputapu tukanga uaua (hei tauira, te whakarōpū whatu, te tātari, te whakaputanga, me ētahi atu) e whakamahia ana i roto i ngā tipu rPET hei whakatutuki i tēnei kua aro nuihia – ā, he tika hoki. Engari, ko ngā pūnaha kawe e neke ana i ngā rauemi i waenga i ēnei taputapu ka tāpirihia i ētahi wā hei whakaaro i muri mai, ka hua ake pea he iti iho i te pai o te mahi a te tipu whānui.
I roto i te mahi hangarua PET, ko te pūnaha kawe te mea e hono ana i ngā mahi katoa – nō reira me hoahoa motuhake mō tēnei rauemi.
Ko te whakahaere i tō tipu ka tīmata mā te hoahoa tipu kounga teitei, ā, kāore e rite te hanga o ngā taputapu whakawhiti katoa.ngā kawe tīwiriKo ngā mea kua tino pai te mahi ki ngā raina maramara i roto i te tekau tau kua pahure ake nei, tera pea he iti rawa te rahi, ā, ka tere te pakaru i ngā raina maramara. Ko te kawe hau e taea te neke i ngā maramara 10,000 pauna/hr, tera pea ka taea anake te neke i ngā maramara 4000 pauna/hr. Ko tētahi hapa noa ko te kore whai i ngā aratohu hoahoa mō te whakahaere i ngā rauemi hangarua.
Ko tētahi kawe hau e taea te nuku maramara 10,000 pauna/haora, ka taea pea e ia te nuku maramara 4000 pauna/haora.
Ko te whakaaro matua hei whakaaroaro ko te iti o te matotoru o ngā maramara pounamu PET ka whakaiti i te kaha tuturu o te pūnaha whakawhiti ki te whakataurite ki te matotoru teitei o ngā rauemi kirikiri. He āhua koretake hoki ngā maramara. Ko te tikanga he nui rawa ngā taputapu mō te tukatuka i ngā rau. Ko te kawe tīwiri mō ngā maramara PET he haurua pea te whānui, ā, e rua hautoru te kaha o te motuka o te kawe tīwiri i hangaia mō ngā maramara. He pūnaha whakawhiti hau e taea ai te neke i te maramara 6000 lb/hr mā roto i te 3 inihi. Me 3 1/2 inihi te rahi o te paipa. Ka taea te whakamahi i ngā ōwehenga totoka ki te hau tae atu ki te 15:1 mō ngā maramara, engari he pai ake te whakahaere i ngā pūnaha maramara me te ōwehenga mōrahi o te 5:1.
Ka taea e koe te whakamahi i te tere kawe hau kotahi mō ngā kongakonga hei whakahaere i ngā matūriki āhua ōrite? Kāo, he iti rawa kia kore ai e nekeneke ngā kongakonga. I roto i te pouaka rokiroki, ko te koeko 60° e taea ai e ngā matūriki te rere ngāwari me waiho hei koeko 70° teitei mō ngā kongakonga. I runga i te rahi o te ipu rokiroki, me whakahohe pea te silo kia rere ai ngā kongakonga. Ko te nuinga o ēnei "ture" ka whakawhanakehia mā te whakamātautau me te hapa, nō reira whakawhirinaki ki ngā kaihangarau whai wheako ki te hoahoa i ngā tukanga mō ngā kongakonga rPET.
Kāore e ranea ētahi o ngā mea rere tuku iho mō ngā mea totoka papatipu mō ngā papa pounamu. Ko te putanga silo e whakaaturia ana i konei ka āwhinahia e tētahi tīwiri piko e pakaru ana i ngā piriti, ā, ka tukuna ngā maramara ki roto i tētahi raka hau hurihuri hei whāngai pono, pumau hoki ki roto i te pūnaha kawe hau.
Kāore te hoahoa pai o te pūnaha kawe waka e kī taurangi i te pono o te pūnaha. Hei whakatutuki i te mahi pono, me hoahoa motuhake ngā wāhanga o te pūnaha kawe waka mō ngā maramara rPET.
Me pakari ngā takirere hurihuri e whāngai ana i ngā kongakonga ki roto i tētahi pūnaha tuku pēhanga, i tētahi atu wāhanga rānei o te tukanga, kia tu atu ai i ngā tau maha o te tukinotanga mai i ngā kongakonga koretake me ngā poke katoa e tika ana mā roto. He nui ake te utu o ngā whare me ngā rotor maitai kore waikura taumaha i ngā hoahoa angiangi o ngā pepa whakarewa, engari ka ea te utu tāpiri mā te whakaiti i te wā kore mahi me te whakaiti i ngā utu whakakapinga taputapu.
He rerekē te āhua o ngā maramara PET hangarua i ngā maramara PET, te matotoru rānei o te matūriki. He mea whakakoi anō hoki.
Me whai rotor āhua-V ngā rotor i roto i ngā takirere hurihuri i hangaia mō te lamella, me te "parau" i te tomokanga hei whakaiti i te haehae me te aukati. I ētahi wā ka whakamahia ngā pito ngāwari hei whakakore i ngā take haehae, engari me tiaki tonu ēnei, ā, ka whakaurua mai hoki ngā kongakonga whakarewa iti ki roto i te tukanga ka raru pea i te taha whakararo.
Nā te āhua whakakoi o ngā kirikiri, he raruraru noa ngā tuke i roto i ngā pūnaha kawe hau. He tere te pūnaha kawe rau, ā, ka paheke te rau i te mata o waho o te tuke mā roto i tētahi ngongo maitai kore waikura taumata 10. He maha ngā kaiwhakarato e tuku ana i ngā tuke motuhake hei whakaiti i tēnei raruraru, ā, ka taea hoki te hanga e ngā kaimahi miihini.
Ka puta te pakaru i ngā piko roa noa i te mea ka paheke ngā totoka whakakoi i te mata o waho i te tere teitei. Whakaarohia te whakamahi i te iti rawa o ngā piko e taea ana, me te whakamahi pea i ngā piko motuhake kua hangaia hei whakaiti i tēnei pakaru.
Ko te whakawhanake me te whakahaere i tētahi mahere tiaki mō te pūnaha kawe o tētahi tipu te taahiraa whakamutunga, nā te mea he maha ngā wāhanga neke e pā tika ana ki ngā kongakonga koretake me te poke. Heoi anō, he maha ngā wā ka warewarehia te tiaki kua whakaritea.
Ko ētahi raka hau hurihuri he hiri toki me whakakī tonu kia kore ai e turuturu. Rapua ngā takirere me ngā hiri toki labyrinth me ngā peera o waho kāore e hiahiatia he tiaki auau. Ina whakamahia ēnei takirere ki ngā tono pepa, he mea tika kia horoia te hiri toki ki te hau taputapu ma. Kia tika te whakatakotoranga o te pēhanga horoi hiri toki (te nuinga o te wā he 5 psig ki runga ake i te pēhanga tuku mōrahi) ā, kei te rere tonu te hau.
Ka taea e ngā rotor takirere hurihuri te whakararu i te nui o te turuturu i roto i ngā pūnaha tuku pēhanga pai. Ka whakaitihia e tēnei turuturu te nui o te hau e tukuna ana i roto i te paipa, ā, ka whakaitihia te kaha katoa o te pūnaha. Ka taea hoki e ia te whakararu i te hononga ki te hopper i runga ake i te raka hau hurihuri, nō reira tirohia te āputa i waenga i te pito o te rotor me te whare i ia wā.
Nā te nui o te puehu, ka tere te aukati i ngā tipu rPET e ngā tātari hau i mua i te tukunga o te hau kawe ki te āhuarangi. Me whakarite kei te mahi tika te ine pehanga rerekētanga, ā, me whakarite kia tirohia e te kaiwhakahaere i ia wā. Ka taea e te puehu PET tino māmā, tino puhoi hoki te aukati, te whakapiri rānei i te putanga o te kaikohi, engari ka taea e te tuku taumata teitei i roto i te koeko tuku te āwhina ki te kite i ēnei aukati i mua i te puta o ngā raruraru nui ake. Me whakarite kia horoia tonutia te puehu e kohikohi ana i roto i te whare putea.
Kāore e taea e tēnei tuhinga te kapi i ngā ture katoa mō te hoahoa pono me te tiaki i ngā pūnaha whakawhiti i roto i ngā tipu rPET, engari ko te tumanako ka mārama koe he maha ngā mea hei whakaaroaro, ā, kāore he mea hei whakakapi i te wheako. Whakaarohia te whai i ngā taunakitanga a ngā kaiwhakarato taputapu kua whakahaere i ngā maramara rPET i mua. Kua oti i ēnei kaihoko te whakamātautau me te hapa katoa, nō reira kāore koe e hiahia ki te mahi i aua mea.
Mō te Kaituhi: Ko Joseph Lutz te Kaiwhakahaere Hoko me te Hokohoko mō Pelletron Corp. Tekau mā rima tau ōna wheako hangarau ki te whakawhanake i ngā otinga whakahaere rauemi kirihou papatipu. I tīmata tana mahi ki Pelletron i roto i te R&D, i reira i ako ai ia i ngā āhuatanga katoa o te hau i roto i tētahi taiwhanga whakamātautau. He maha ngā pūnaha kawe hau kua tonohia e Lutz puta noa i te ao, ā, e toru ngā mana pateni hua hou kua whakawhiwhia ki a ia.
Ka whakaatuhia te hangarau hou ki NPE i te marama e tū mai nei, hei whakatūpato i te wā e hiahiatia ai te tiaki ārai i mua i te whakararuraru o ngā pakarutanga o ngā taputapu i te mahi whakaputa.
Ki te whakatauritea ki te utu o te hoko kapia kua oti te tae, te tāuta rānei i tētahi mīhini whakaranu matua kaha-nui hei whakaranu i te kapia me te mahi matua, ka taea e te tae i runga i te mīhini te whakarato i ngā painga utu nui, tae atu ki te whakaiti i ngā utu rokiroki rauemi me te whakanui ake i te ngāwari o te tukanga.
Mō ngā pūnaha kawe korehau mō te tukatuka kirihou, kāore e hiahiatia ana ngā otinga whakahaere paura ritenga i ngā wā katoa. Ko ngā otinga kua oti te hanga te whiriwhiri pai mō ngā paura me ngā matū totoka papatipu i roto i te whānuitanga o ngā ahumahi.
