Tekinoloje yolekanitsa ndi imodzi mwamakina atatu akuluakulu opanga mankhwala.Njira yolekanitsa imakhudza kwambiri khalidwe la mankhwala, mphamvu, kugwiritsidwa ntchito ndi kupindula.Makina a TFE Mechanically-agitated Short Path Distillation Machine ndi chipangizo chomwe chimagwiritsidwa ntchito popatukana chifukwa cha kusakhazikika kwa zinthuzo.Chipangizochi chimakhala ndi kutentha kwakukulu kwa kutentha, kutentha kwa mpweya wochepa, nthawi yochepa yokhalamo, kutentha kwapamwamba komanso kuphulika kwakukulu.Amagwiritsidwa ntchito kwambiri m'mafakitale a petrochemicals, mankhwala abwino, mankhwala aulimi, chakudya, mankhwala ndi uinjiniya wa biochemical, kuyendetsa njira za evaporation, ndende, kuchotsa zosungunulira, kuyeretsa, kuvula nthunzi, kutulutsa mpweya, kununkhira, etc.
Short Path Distillation ndi evaporator yatsopano komanso yothandiza yomwe imatha kutulutsa mpweya wa filimu pansi pa vacuum, momwe filimuyo imapangidwira mokakamiza ndi chogwiritsira ntchito filimu yozungulira ndipo imakhala ndi liwiro lothamanga, kutentha kwapamwamba komanso nthawi yochepa yokhalamo (pafupifupi). 5-15 masekondi).Lilinso ndi kutentha kwakukulu kwa kutentha, mphamvu ya evaporation, nthawi yochepa yothamanga komanso kusinthasintha kwakukulu kwa ntchito, komwe kumakhala koyenera kwambiri ndende ndi evaporation, degassing, zosungunulira kuchotsa, distillation ndi kuyeretsa zipangizo kutentha kutentha, mkulu mamasukidwe akayendedwe zipangizo ndi zosavuta. kristalo ndi zida zokhala ndi tinthu.Amakhala ndi silinda imodzi kapena zingapo zokhala ndi jekete zowotchera komanso chopangira filimu chozungulira mu silinda.Wogwiritsa ntchito filimuyo amakanda mosalekeza za chakudya kukhala filimu yamadzi yofananira pamalo otentha ndikukankhira pansi, pomwe zida zokhala ndi zowira zochepa zimawuka ndipo zotsalira zake zimatuluka pansi pa evaporator.
II.Makhalidwe Antchito
•Kuchepa kwa vacuum pressure:
Pamene mpweya wa vaporized wa zinthuzo uchoka pamoto wotentha kupita ku condenser yakunja, pamakhala mphamvu yosiyana.Mu evaporator wamba, kutsika kotereku (Δp) nthawi zambiri kumakhala kokwera, nthawi zina kumlingo wosavomerezeka.Mosiyana ndi izi, Short Path Distillation Machine ili ndi malo akuluakulu a gasi, kupanikizika kwake komwe kumakhala kofanana ndi komwe kuli mu condenser;kotero, pali kutsika kwapang'onopang'ono ndipo digiri ya vacuum ikhoza kukhala ≤1Pa.
• Kutentha kocheperako:
Chifukwa cha zinthu zomwe zili pamwambazi, njira ya evaporation imatha kuchitidwa pamlingo wapamwamba wa vacuum.Popeza kuchuluka kwa vacuum kumawonjezeka, malo otentha ofananira azinthu amachepetsa mwachangu.Choncho, ntchitoyi ikhoza kuchitidwa pa kutentha kochepa ndipo kuwonongeka kwamafuta kwa mankhwalawa kumachepetsedwa.
• Kutentha kwanthawi kochepa:
Chifukwa cha mawonekedwe apadera a Short Path Distillation Machine ndi kupopera kwa chogwiritsira ntchito filimu, nthawi yokhala ndi zipangizo mu evaporator ndi yochepa;Komanso, chipwirikiti mofulumira filimu mu Kutentha evaporator kumapangitsa mankhwala kulephera kukhala pa evaporator pamwamba.Choncho, makamaka oyenera evaporation wa zipangizo kutentha tcheru.
• Kuchuluka kwa evaporation:
Kuchepetsa kutentha kwa zinthu kumawonjezera kutentha kwa kutentha kwa TV;ntchito ya filimu applicator amachepetsa makulidwe a filimu madzi mu chipwirikiti boma ndi kuchepetsa kukana matenthedwe.Panthawiyi, ndondomekoyi imalepheretsa kuyika ndi kupukuta kwa zipangizo pamtunda wotentha ndipo imatsagana ndi kusinthanitsa kwabwino kwa kutentha, motero kumawonjezera kutentha kwapadera kwa evaporator.
• Kusinthasintha kwakukulu kwa ntchito:
Chifukwa cha zinthu zake zapadera, evaporator ya filimu ya scraper ndi yoyenera kuchiza zipangizo zowononga kutentha zomwe zimafuna kuti mpweya ukhale wofewa komanso wosasunthika komanso zipangizo zamakono zomwe kukhuthala kwake kumakula kwambiri ndi kuwonjezeka kwa ndende, monga momwe zimakhalira zowonongeka komanso zokhazikika.
Ndi abwino kwa evaporation ndi distillation zipangizo munali particles kapena milandu crystallization, polymerization ndi fouling.
III.Magawo Ofunsira
The scraper film evaporator yakhala ikugwiritsidwa ntchito kwambiri pantchito zosinthira kutentha.Zimathandizira kusinthana kwa kutentha kwa zinthu zowononga kutentha (nthawi yochepa) makamaka, ndipo zimatha kusokoneza zinthu zovuta ndi ntchito zake zosiyanasiyana.
The scraper film evaporator wakhala akugwiritsidwa ntchito ndende ndi evaporation, kuchotsa zosungunulira, nthunzi-kuvula, reaction, degassing, deodorization (de-aeration), etc. m'madera otsatirawa, ndipo wapeza zotsatira zabwino:
Traditional Chinese mankhwala ndi Western mankhwala: mankhwala, shuga mowa, bingu godvine, astragalus ndi zitsamba zina, methylimidazole, single nitrile amine ndi intermediates ena;
Zakudya zopepuka zamafakitale: madzi, gravy, pigment, essences, zonunkhira, zymin, lactic acid, xylose, shuga wowuma, potaziyamu sorbate, etc.
Mafuta ndi mankhwala a tsiku ndi tsiku: lecithin, VE, mafuta a chiwindi a cod, oleic acid, glycerol, mafuta acids, mafuta odzola, alkyl polyglycosides, mowa ether sulfates, etc.
Synthetic resins: polyamide resins, epoxy resins, paraformaldehyde, PPS (polypropylene sebacate esters), PBT, formic acid allyl esters, etc.
Synthetic ulusi: PTA, DMT, mpweya CHIKWANGWANI, polytetrahydrofuran, polyether polyols, etc.
Petrochemistry: TDI, MDI, trimethyl hydroquinone, trimethylolpropane, sodium hydroxide, etc.
Mankhwala ophera tizilombo: acetochlor, metolachlor, chlorpyrifos, furan phenol, clomazone, mankhwala ophera tizirombo, herbicides, miticides, etc.
