Ka Hoʻohana ʻana o ka Mīkini Hoʻoheheʻe Ala Pōkole Kiʻiʻoniʻoni i holoi ʻia

I. Hoʻolauna
ʻO ka ʻenehana hoʻokaʻawale kekahi o nā ʻenehana hana kemika nui ʻekolu. He hopena nui ke kaʻina hana hoʻokaʻawale i ka maikaʻi o ka huahana, ka pono, ka hoʻohana ʻana a me ka pono. ʻO ka TFE Mechanically-agitated Short Path Distillation Machine kahi mea hana i hoʻohana ʻia e hana i ka hoʻokaʻawale ʻana ma o ka volatility o nā mea. Loaʻa i kēia mea hana kahi coefficient hoʻoili wela kiʻekiʻe, ka mahana evaporation haʻahaʻa, ka manawa noho mea pōkole, ka pono thermal kiʻekiʻe a me ka ikaika evaporation kiʻekiʻe. Hoʻohana nui ʻia ia i nā ʻoihana o nā petrochemicals, nā kemika maikaʻi, nā kemika mahiʻai, ka meaʻai, nā lāʻau lapaʻau a me ka ʻenekinia biochemical, e hana i nā kaʻina hana o ka evaporation, ka noʻonoʻo ʻana, ka wehe ʻana i ka solvent, ka hoʻomaʻemaʻe ʻana, ka wehe ʻana i ka mahu, ka degassing, deodorization, a pēlā aku.

ʻO ka Short Path Distillation kahi evaporator hou a maikaʻi hoʻi e hiki ke hoʻokō i ka hoʻoheheʻe ʻana o ka ʻili ma lalo o nā kūlana vacuum, kahi i hana ikaika ʻia ai ka ʻili e ka mea hoʻopili ʻili e wili ana a he wikiwiki ke kahe ʻana, ka pono o ka hoʻoili wela kiʻekiʻe a me ka manawa noho pōkole (ma kahi o 5-15 kekona). Loaʻa iā ia kahi coefficient hoʻoili wela kiʻekiʻe, ka ikaika hoʻoheheʻe kiʻekiʻe, ka manawa kahe pōkole a me ka maʻalahi o ka hana, kahi kūpono loa no ka hoʻohuihui ʻana ma o ka hoʻoheheʻe ʻana, ka degassing, ka wehe ʻana i ka solvent, ka distillation a me ka hoʻomaʻemaʻe ʻana i nā mea wela-sensitive, nā mea viscosity kiʻekiʻe a me nā mea kristal a me nā ʻāpana maʻalahi. Loaʻa iā ia hoʻokahi a ʻoi aku paha nā cylinders me nā ʻaʻahu no ka hoʻomehana ʻana a me kahi mea hoʻopili ʻili e wili ana i loko o ka cylinder. Hoʻomau ka mea hoʻopili ʻili i nā mea hānai i loko o kahi ʻili wai like ma ka ʻili hoʻomehana a hoʻokuke iā lākou i lalo, i ka wā e hoʻoheheʻe ai nā ʻāpana me nā kiko paila haʻahaʻa a hoʻokuʻu ʻia ko lākou mau koena mai lalo o ka evaporator.

II. Nā ʻano hana
•Haʻahaʻa ka emi ʻana o ke kaomi hakahaka:
Ke neʻe aku ke kinoea mahu o nā mea mai ka ʻili hoʻomehana i ka condenser waho, aia kekahi kaomi ʻokoʻa. I loko o kahi evaporator maʻamau, ʻo ia ʻano emi ʻana o ke kaomi (Δp) he kiʻekiʻe loa ia, i kekahi manawa i kahi kekelē hiki ʻole ke ʻae ʻia. I ka hoʻohālikelike ʻana, ʻoi aku ka nui o ka hakahaka kinoea o ka Mīkini Distillation Ala Pōkole, ʻaneʻane like ke kaomi me ko ka condenser; no laila, aia kahi emi iki o ke kaomi a hiki i ke kekelē vacuum ke ≤1Pa.
• Haʻahaʻa ka mahana hana:
Ma muli o ke ʻano i luna, hiki ke hana ʻia ke kaʻina hana hoʻomaloʻo ma ke kekelē vacuum kiʻekiʻe. Ma muli o ka piʻi ʻana o ke kekelē vacuum, e emi koke ana ke kiko paila o nā mea. No laila, hiki ke hana ʻia ka hana ma kahi mahana haʻahaʻa a no laila e hoʻemi ʻia ka decomposition thermal o ka huahana.
• Ka manawa hoʻomehana pōkole:
Ma muli o ke ʻano kūikawā o ka Mīkini Hoʻoheheʻe Ala Pōkole a me ka hana pumping o ka mea hoʻopili kiʻiʻoniʻoni, he pōkole ka manawa noho o nā mea i loko o ka evaporator; eia kekahi, ʻo ka wikiwiki o ka haunaele o ke kiʻiʻoniʻoni i loko o ka evaporator hoʻomehana e hiki ʻole ai i ka huahana ke noho ma luna o ka ʻili o ka evaporator. No laila, kūpono loa ia no ka mahu ʻana o nā mea i ʻike ʻia i ka wela.

• Ka ikaika o ka mahu ʻana:
ʻO ka hōʻemi ʻana o ke kiko paila o nā mea e hoʻonui ai i ka ʻokoʻa o ka mahana o nā mea hoʻomehana; ʻo ka hana o ka mea hoʻopili kiʻiʻoniʻoni e hoʻemi ana i ka mānoanoa o ka ʻili wai i loko o kahi kūlana haunaele a hoʻemi i ke kūpaʻa wela. I kēia manawa, ke kāohi nei ke kaʻina hana i ka caking a me ka haumia o nā mea ma luna o ka ʻili hoʻomehana a hele pū ʻia me ka hoʻololi wela maikaʻi, no laila e hoʻonui ana i ke koina hoʻoili wela holoʻokoʻa o ka evaporator.

• Ka maʻalahi o ka hana nui:
Ma muli o kona mau waiwai kūikawā, kūpono ka evaporator ʻili scraper no ka mālama ʻana i nā mea ʻike wela e pono ai ka evaporation maʻalahi a paʻa a me nā mea viscosity kiʻekiʻe e hoʻonui nui ʻia ka viscosity me ka hoʻonui ʻana o ka noʻonoʻo, ʻoiai he maʻalahi a paʻa ke kaʻina evaporation.

He kūpono hoʻi ia no ka hoʻomaloʻo ʻana a me ka distillation o nā mea i loaʻa nā ʻāpana a i ʻole i nā hihia o ka crystallization, polymerization a me ka fouling.

III. Nā Wahi Hoʻohana
Ua hoʻohana nui ʻia ka mīkini hoʻoheheʻe kiʻiʻoniʻoni scraper i nā papahana hoʻololi wela. Kōkua ia i ka hoʻololi wela o nā mea pili i ka wela (manawa pōkole) ʻoi aku hoʻi, a hiki ke hoʻoheheʻe i nā huahana paʻakikī me kāna mau hana like ʻole.
Ua hoʻohana ʻia ka scraper film evaporator no ka hoʻohuihui ʻana ma o ka hoʻoheheʻe ʻana, ka wehe ʻana i ka solvent, ka hoʻokaʻawale ʻana i ka mahu, ka hopena, ka degassing, ka deodorization (de-aeration), a pēlā aku ma nā wahi aʻe, a ua loaʻa nā hopena maikaʻi:
