ʻO ka ʻenehana hoʻokaʻawale kekahi o nā ʻenehana hana kemika nui ʻekolu. He hopena nui ke kaʻina hana kaʻawale i ka maikaʻi o ka huahana, ka pono, ka hoʻohana a me ka pōmaikaʻi. ʻO ka TFE Mechanically-agitated Short Path Distillation Machine kahi mea i hoʻohana ʻia e hana i ka hoʻokaʻawale ʻana ma o ka volatility o nā mea. He kiʻekiʻe ka hoʻoneʻe wela o kēia mea hana, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, pōkole mea noho manawa, kiʻekiʻe ka wela wela a me ka ikaika evaporation kiʻekiʻe. Hoʻohana nui ʻia ia i nā ʻoihana o nā petrochemical, nā kemika maikaʻi, nā mea kanu mahiʻai, nā meaʻai, nā lāʻau lapaʻau a me nā ʻenekini biochemical, e hana i nā kaʻina hana o ka evaporation, ka hoʻopaʻa ʻana, ka wehe ʻana i ka solvent, ka hoʻomaʻemaʻe, ka huki ʻana i ka mahu, degassing, deodorization, etc.
ʻO ka Short Path Distillation kahi evaporator hou a maikaʻi hoʻi e hiki ai ke hoʻokō i ka hāʻule ʻana o ke kiʻiʻoniʻoni ma lalo o nā kūlana vacuum, kahi i hana ikaika ʻia ai ke kiʻiʻoniʻoni e ka mea hoʻopili kiʻi ʻoniʻoni a loaʻa ka wikiwiki holo kiʻekiʻe, kiʻekiʻe ka hoʻoili wela wela a me ka manawa noho pōkole (e pili ana i 5-15 kekona). Loaʻa iā ia ka coefficient hoʻoili wela kiʻekiʻe, ka ikaika evaporation kiʻekiʻe, ka manawa kahe pōkole a me ka maʻalahi o ka hana nui, kūpono loa ia no ka neʻe ʻana ma o ka evaporation, degassing, wehe ʻana i ka solvent, distillation a me ka hoʻomaʻemaʻe ʻana i nā mea wela, nā mea viscosity kiʻekiʻe a maʻalahi. nā mea aniani a me nā mea ʻeleʻele. Loaʻa ia i hoʻokahi a ʻoi aku paha nā cylinders me nā ʻaʻahu no ka hoʻomehana ʻana a me kahi applicator kiʻiʻoniʻoni e hoʻololi ana i ka cylinder. Hoʻopaʻa mau ka mea hoʻohana kiʻiʻoniʻoni i nā mea hānai i loko o kahi kiʻiʻoniʻoni wai like ʻole ma ka ʻili wela a hoʻokuʻu iā lākou i lalo, i ka wā e hoʻoheheʻe ʻia ai nā mea me nā wahi paila haʻahaʻa a hoʻokuʻu ʻia nā koena mai lalo o ka evaporator.
II. Nā ʻano hana
• hāʻule haʻahaʻa haʻahaʻa haʻahaʻa:
Ke hoʻololi ʻia ke kinoea mahuka o nā mea mai ka ʻili wela a i ka condenser o waho, aia kekahi ʻano ʻokoʻa. I loko o kahi evaporator maʻamau, ʻoi aku ka kiʻekiʻe o kēlā hāʻule puʻe (Δp), i kekahi manawa i kahi degere ʻae ʻole. ʻO ka ʻokoʻa, ʻo ka Short Path Distillation Machine he wahi kinoea nui aʻe, ʻo ke kaomi o ia mea ua aneane like me ka condenser; no laila, aia kahi hāʻule kaomi liʻiliʻi a hiki ke ≤1Pa ke degere vacuum.
• Haʻahaʻa hana wela:
Ma muli o ka waiwai i luna, hiki ke hana ʻia ke kaʻina evaporation ma kahi kiʻekiʻe vacuum degere. Ma muli o ka piʻi ʻana o ke degere vacuum, e emi koke ana ka paila paila o nā mea. No laila, hiki ke hana ʻia ka hana ma kahi haʻahaʻa haʻahaʻa a hoʻemi ʻia ka decomposition thermal o ka huahana.
• Ka manawa hoʻomehana pōkole:
Ma muli o ke ʻano kū hoʻokahi o ka Mīkini Kūʻai ʻo Short Path Distillation a me ka hana pumping o ka applicator kiʻiʻoniʻoni, pōkole ka manawa noho o nā mea i loko o ka evaporator; Eia kekahi,ʻo ka wikiwiki wikiwiki o ke kiʻiʻoniʻoni i ka evaporator mehana e hikiʻole ai i ka huahana ke noho ma luna o ka evaporator surface. No laila, kūpono loa ia no ka evaporation o nā mea wela.
• Kiekie evaporation ikaika:
ʻO ka ho'ēmiʻana o ka paila paila o nā mea e hoʻonui ai i kaʻokoʻa wela o ka media wela; ʻo ka hana a ka mea hoʻopili kiʻiʻoniʻoni e hoʻemi i ka mānoanoa o ka kiʻiʻoniʻoni wai i loko o kahi kūlana haunaele a hoʻemi i ka pale wela. I kēia manawa, hoʻopau ke kaʻina hana i ka caking a me ka hoʻoheheʻe ʻana o nā mea ma luna o ka wela wela a hele pū ʻia me ka hoʻololi wela maikaʻi, no laila e hoʻonui ai i ka nui o ka hoʻoili wela o ka evaporator.
• ʻO ka hiki ke hana nui:
Ma muli o kona mau waiwai kū hoʻokahi, ua kūpono ka scraper film evaporator no ka mālama ʻana i nā mea wela e pono ai ka hoʻoheheʻe ʻana a me ka paʻa a me nā mea kiʻekiʻe-viscosity e piʻi nui ana ka viscosity me ka piʻi ʻana o ka noʻonoʻo ʻana, ʻoiai ʻo kāna kaʻina evaporation maʻalahi a paʻa.
He kūpono no ka evaporation a me ka distillation o nā mea i loaʻa nā ʻāpana a i ʻole nā hihia o ka crystallization, polymerization a me ka fouling.
III. Wahi noi
Ua hoʻohana nui ʻia ka scraper film evaporator i nā papahana hoʻololi wela. Kōkua ia i ka hoʻololi wela o nā mea wela (manawa pōkole) ʻoi aku, a hiki ke hoʻokaʻawale i nā huahana paʻakikī me kāna mau hana like ʻole.
Ka scraper film evaporator ua hoʻohana 'ia no ka noonoo ana ma ka evaporation, solvent wehe, mahu-stripping, reaction, degassing, deodorization (de-aeration), etc.
