ʻO ka ʻōmole PET holoi holoi ʻana i ka mīkini

He ʻōnaehana hana piha ka ʻōmole PET e wāwahi ana i ka mīkini holoi holoi e hana ana i nā ʻōmole PET i hoʻolei ʻia (e like me nā ʻōmole wai mineral a me nā ʻōmole inu) i loko o nā flakes PET maʻemaʻe ma o nā kaʻina hana automated. ʻO kēia mau ʻāpana ʻōmole he mau mea waiwai nui no ka hana ʻana i nā fibers pōkole polyester, nā lau, a me nā ʻōmole hou.

ʻO kēia laina hana ka mea nui no ka hoʻokō ʻana i ka pōʻai pōʻai pōʻai PET (bottle to bottle cycle).

ʻO ka mīkini holoi holoi holoi holoi piha piha ʻana i ka hue PET piha i nā kaʻina hana ʻeono:

1. Hoʻoponopono mua - wehe a hoʻokaʻawale

· Ke kumu: E wehe mua i nā haumia a hoʻomākaukau no ka hana ma hope.

· Lako: mīkini wehe ʻana, kāʻei conveyor, paepae hoʻokaʻawale lima (a i ʻole robot hoʻokaʻawale ʻokoʻa).

· Ke Kaʻina Hana: Wehe ʻia a lawe ʻia nā ʻeke ʻōpala i hoʻopaʻa ʻia e ke kāʻei conveyor, a ʻike ʻia nā mea haumia ʻole PET (e like me nā ʻāpana nui o ka metala, aniani, nā ʻōmole PVC, nā ipu ʻilika ʻē aʻe, pepa, a me nā mea ʻē aʻe) e wehe ʻia me ka lima a i ʻole e ka ʻōnaehana ʻike mīkini.

2. Hoemi - ka nui

· Ke kumu: E wāwahi i ka ʻōmole holoʻokoʻa i ʻāpana liʻiliʻi no ka hoʻomaʻemaʻe hohonu a me ka hoʻokaʻawale ʻana.

· Mea lako: shredder a crusher (i hoʻolālā mau ʻia me ka ʻako ʻāʻī).

· Ke Kaʻina Hana: Komo ka ʻōmole i loko o ke keʻena crusher i hoʻopaʻa ʻia ma o ke kāʻei conveyor a ʻokiʻoki ʻia i loko o nā ʻāpana like ʻole (maʻamau 12-20mm) e nā lau ʻōwili kiʻekiʻe. I ka wā o ka ʻohi ʻana, e pīpī ʻia kahi wai liʻiliʻi i mea e pale ai i ka hoʻoheheʻe ʻana a me ka hoʻopaʻa ʻana o ka plastik ma muli o ka hoʻoulu ʻana o ka friction (i ʻike ʻia ʻo "hot melt"), a no ka holoi mua ʻana i kekahi o ka sediment.

3. Hoʻomaʻemaʻe - ʻO ka wehe ʻana i nā mea haumia ke kī i ka laina hana holoʻokoʻa, maʻamau i māhele ʻia i nā kaʻina hana he nui e holomua ana i kēlā me kēia papa.

· Hoʻomaʻemaʻe mua a hoʻomaʻemaʻe ʻia:

· Ke kumu: E wehe ikaika i nā lepili paʻakikī, ke kāpili, ka lepo, a me ka momona i hoʻopaʻa ʻia i nā papa ʻōmole.

· Lako: ʻO ka mīkini hoʻomaʻemaʻe friction (ʻike ʻia ʻo "mīkini scrubbing").

· Ke Kaʻina Hana: ʻO ka ʻōmole, ka wai, a me ka mea hoʻomaʻemaʻe e holoi ikaika ʻia i loko o kahi pahu hili ma o ka hoʻoulu ʻia ʻana o nā lau spiral a me ka hakakā ma waena o nā mea. Hoʻokuʻu ʻia ka wai lepo ma ka kānana lalo.

ʻO ka hoʻokaʻawale ʻana o ka wai/ka hoʻokaʻawale hydraulic:

· Ke kumu: E hoʻokaʻawale i ka PET a me nā haumia me ka hoʻohana ʻana i nā ʻokoʻa like ʻole.

· Mea lako: pahu hoʻomaʻemaʻe flotation a i ʻole hydraulic cyclone.

· Kaʻina hana:

· Nā ʻāpana omole PET: me ka ʻoi aku ka nui ma mua o ka wai (~ 1.38 g/cm ³), e pohō lākou i lalo o ka loko wai a hoʻokuʻu ʻia e ka mea lawe wili.

· ʻO ka pahu pahu waiwai (PP/PE): me ka haʻahaʻa haʻahaʻa ma mua o ka wai (~ 0.90-0.96 g/cm ³), e lana ia ma ka ʻili wai a hoʻokaʻawale ʻia e ka ʻōpala a i ʻole ke kahe.

· He hana koʻikoʻi kēia i ka hoʻokaʻawale ʻana i ka pāpale ʻōmole mai ke kino o ka ʻōmole.

· ʻO ka holoi holoi alkaline kiʻekiʻe:

· Ke Kumu: E hoʻopau loa i nā mea haumia kūlohelohe e like me ka ʻaila, ke koena kō, a me ke kāpili, a me ka hoʻomaʻemaʻe ʻana a me ka pepehi ʻana i ka maʻi bacteria.

· Lako: pahu holoi wela a pahu holoi wela paha.

· Ke Kaʻina Hana: Hoʻomoʻi ʻia nā ʻāpana ʻōmole i loko o ka wai hoʻomaʻemaʻe alkaline wela (ʻo ka hopena maʻamau ʻo NaOH, ka mahana ma luna o 80 degere) a hoʻoulu lohi ʻia e emulsify a decompose pollutants.

· Holoi:

· Ke Kumu: E holoi pono i ke koena mea hoʻomaʻemaʻe a wehe i ka lepo ma nā ʻāpana ʻōmole i holoi ʻia me ka alkali.

· Lako: ʻO ka pahu hoʻomaʻemaʻe pae nui a i ʻole ka mīkini holoi pahu.

· Ke Kaʻina Hana: ʻO ka hoʻohana ʻana i ke kumu o ka holoi ʻana i ke kahe ʻana, ʻo ia hoʻi, komo nā ʻāpana ʻōmole maʻemaʻe i ka wai maʻemaʻe, a ʻo ke ʻano o ka kahe wai e kūʻē i ke kuhikuhi o ka holomua waiwai, i mea e hoʻokō ai i ka mālama wai a me ka hopena hoʻomaʻemaʻe maikaʻi loa.

4. Dehydration - dehydration mechanical

· Pahuhopu: E wehe i ka wai manuahi e like me ka hiki mai ka ʻili o nā ʻāpana ʻōmole ma mua o ke komo ʻana i ka ʻōnaehana maloʻo, i mea e hōʻemi nui ai i ka hoʻohana ʻana i ka ikehu maloʻo.

· Lako: Centrifugal dewatering machine.

· Ke Kaʻina Hana: Ma hope o ka hoʻomaʻemaʻe ʻana, komo nā ʻāpana ʻōmole pulu i ka hīnaʻi centrifuge kiʻekiʻe. Ma lalo o ka ikaika centrifugal nui, hoʻolei ʻia ka wai a hoʻokuʻu ʻia ma nā lua kānana ma ka pā hīnaʻi, a hiki ke hoʻemi ʻia ka maʻi o ka mea ma lalo o 10%.

5. Hoʻomaloʻo - Hoʻomāmā

· Ke kumu: E hoʻopau loa i ke koena o ka wai i loko a ma luna o ka ʻili o ka ʻōmole dehydrated, i hoʻokō ʻia i nā koi no ka hoʻoili ʻana a i ʻole ka mālama ʻana ma hope (ʻo ka mea maʻamau e koi ʻia e emi iho ma mua o 1%).

· Mea lako: Airflow maloʻo ʻōnaehana (maʻamau), friction dryer, etc.

· Ke Kaʻina Hana: Hoʻopili piha ka ea wela kiʻekiʻe a me ka -wikiwiki wela me nā ʻāpana omole, e lawe ana i ka makū a hana ʻia ke kinoea wela a me ka wela. Hoʻomaʻalili ʻia nā ʻāpana ʻōmole maloʻo e ka ʻōnaehana hoʻoluʻu a laila hoʻokuʻu ʻia.

6. Packaging a me ka waiho ʻana

· Ke kumu: E hoʻopili pono i ka huahana i hoʻopau ʻia i mea e pale ai i ka makū a me ka haumia.

· Mea lako: silo, mīkini pahu pahu, mīkini ʻeke ʻeke ton.

· Ke Kaʻina Hana: Ma hope o ka maloʻo ʻana, kānana ʻia nā ʻāpana ʻōmole PET maʻemaʻe mai loko mai o nā ʻāpana liʻiliʻi e ka mīkini pale haʻalulu a mālama ʻia i loko o kahi pahu waiwai. ʻO ka hope, ua kaupaona ʻia lākou a hoʻopaʻa ʻia i loko o nā ʻeke nui a i ʻole nā ​​ʻeke ton.

ʻO ka ʻōpala ʻōpala hānai → wehe i ka mīkini → conveyor kāʻei (manual/mechanical sorting) → crusher (me ka wai wai) → friction cleaning machine → flotation separation tank (separating PP/PE bottle caps) → kiʻekiʻe -mahanahana alkali holoi pahu → lehulehu mīkini paʻi → maʻemaʻe PET ʻōmole huahana hope loa a me ka noi

· Huahana: Clean PET Flakes

· Nā hiʻohiʻona: keʻokeʻo a me ka maʻemaʻe hiʻohiʻona, haʻahaʻa haʻahaʻa haumia, a me ka haʻahaʻa haʻahaʻa.

· Ke kumu nui:

1. Milo: Ka hana 'ana i nā pulupulu polyester no ka ho'opiha 'ana i nā mea (e like me ka pulupulu ho'opiha pā'ani), nā lole 'ole{1}}, a me nā lole lole.

2. Pepa: Ka hana ʻana i nā pepa APET no ka hoʻopili ʻana i nā meaʻai, nā ʻōpala blister, etc.

3. Granulation: PET recycled pellets (rPET pellets) ua hoʻoheheʻe ʻia a hoʻoheheʻe ʻia e kahi extruder screw, hiki ke hoʻohana ʻia no ka hoʻoheheʻe ʻana a i ʻole ka puhi ʻana i ka pahu i loko o nā pahu pili meaʻai ʻole.

4. ʻO ka ʻōmole i ka ʻōmole: Ma hope o ka hoʻomaʻemaʻe hohonu a me nā kaʻina hana mānoanoa paʻa -phase thickening (SSP), hiki ke hoʻohana ʻia e hana i nā ʻōmole mea inu hou.

1. ʻenehana hoʻokaʻawale: ʻO ka hoʻokaʻawale maikaʻi ʻana o ke kino o ka ʻōmole PET (transparent, blue, green) mai ka ʻōmole ʻōmole HDPE, ka pepa lepili PP, ke apo alumini, ke kāpili, a me nā plastics ʻē aʻe ke kumu e hōʻoia ai i ka maʻemaʻe o ka huahana i hoʻopau ʻia. E hoʻohana ana nā hale hana kiʻekiʻe ma kahi kokoke i-mekini hoʻokaʻawale infrared (NIR) no ke kala pololei a me ka hoʻokaʻawale ʻana i nā mea ma mua a ma hope o ka ʻohi ʻana.

2. Ka hoʻomaʻemaʻe wai: ʻO ke kaʻina hana hoʻomaʻemaʻe e hoʻopuka i ka nui o ka wai ʻino, a pono e kūkulu i kahi ʻōnaehana hoʻomaʻemaʻe wai (e like me ka sedimentation, ka lele ʻana o ka ea, ka mālama biochemical, a me nā mea ʻē aʻe) no ka hoʻokō ʻana i ka wai ʻōpala a i ʻole ka hoʻokuʻu maʻamau, inā ʻaʻole ia e hoʻohaumia i ka lua.

3. ʻO ka hoʻohana ʻana i ka ikehu: ʻO ka maloʻo ka loulou nui e hoʻopau i ka ikehu, no laila he mea koʻikoʻi nā mea hoʻoheheʻe wai.

4. ʻO ka pae otomation: ʻO ke kiʻekiʻe o ka pae automation, ʻoi aku ka haʻahaʻa o ka uku hana, ʻoi aku ka paʻa o ka maʻemaʻe o ka huahana, akā ʻoi aku ka nui o ka hoʻopukapuka mua.

Manaʻo wau e hiki i kēia wehewehe kikoʻī ke kōkua iā ʻoe e hoʻomaopopo piha i ka mīkini holoi holoi holoi holoi PET. Inā loaʻa iā ʻoe nā kikoʻī kikoʻī āu e makemake ai e aʻo hou e pili ana, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou no ke kūkākūkā.

1. Loaʻa ka maikaʻi o nā huahana hope. I ka hana ʻana i nā hue PET, ka haʻahaʻa o nā huahana hope loa ma lalo o 1%.
2. ʻO ka mīkini me ka hana kiʻekiʻe, ka hana paʻa, ka mana nui etc.
3. ʻO nā ʻāpana e pili ana i nā mea e hoʻohana ai i ka SUS304, ʻoi aku ka mānoanoa ma mua o 3mm, e hōʻoia i ka lōʻihi o ke ola ʻana.
4. Hoʻohana ʻia nā ʻāpana brand kaulana o ka honua ma ka laina hana - SKF bearing, Siemens contactor, Japan Omron temperature controller, ABB invertor, Siemens PLC control.

Nā huahana pale: ʻO ka'ōmole pipi eʻoki ana i ka mīkini holoi hana hou, Kina ka'ōmole pipi e holoi ana i ka mīkini hana hou, nā mea kūʻai, hale hana.
