Ukusetshenziswa Komshini Wokuhlanza Ifilimu Efihlwe Kafushane

I. Isingeniso
Ubuchwepheshe bokuhlukanisa bungenye yezindlela ezintathu ezinkulu zokukhiqiza amakhemikhali. Inqubo yokuhlukanisa inomthelela omkhulu kwikhwalithi yomkhiqizo, ukusebenza kahle, ukusetshenziswa kanye nenzuzo. Umshini Wokucwilisa Indlela Emfushane we-TFE oshukunyiswa ngomshini uyithuluzi elisetshenziselwa ukwenza ukwahlukana ngokuguquguquka kwezinto. Le divayisi ine-coefficient ephezulu yokudlulisa ukushisa, izinga lokushisa eliphansi lokuhwamuka, isikhathi esifushane sokuhlala kwezinto, ukusebenza kahle kokushisa okuphezulu kanye namandla aphezulu okuhwamuka. Isetshenziswa kabanzi embonini yamakhemikhali kaphethroli, amakhemikhali amahle, amakhemikhali ezolimo, ukudla, imithi kanye nobunjiniyela be-biochemical, ukuqhuba izinqubo zokuhwamuka, ukuhlushwa, ukususwa kwesinyibilikisi, ukuhlanza, ukususa umusi, ukususa igesi, ukususa iphunga, njll.

I-Short Path Distillation iyi-evaporator entsha nephumelelayo engenza ukuhwamuka kwefilimu ewayo ngaphansi kwezimo ze-vacuum, lapho ifilimu yenziwa ngenkani yi-applicator yefilimu ejikelezayo futhi inesivinini esikhulu sokugeleza, ukusebenza kahle kokudlulisa ukushisa okuphezulu kanye nesikhathi esifushane sokuhlala (cishe imizuzwana emi-5-15). Iphinde ibe ne-coefficient ephezulu yokudlulisa ukushisa, amandla aphezulu okuhwamuka, isikhathi esifushane sokugeleza kanye nokuguquguquka okukhulu kokusebenza, okufanelekela kakhulu ukuhlushwa ngokuhwamuka, ukukhipha igesi, ukususa i-solvent, ukuhluzwa kanye nokuhlanzwa kwezinto ezizwela ukushisa, izinto eziphezulu ze-viscosity kanye nezinto ezilula ze-crystal kanye nezinhlayiya. Iqukethe isilinda esisodwa noma ngaphezulu esinamajakethi okushisa kanye ne-applicator yefilimu ejikelezayo kusilinda. I-applicator yefilimu iqhubeka nokukhuhla izinto zokudla zibe yifilimu efanayo yoketshezi ebusweni bokushisa bese izisunduzela phansi, lapho izingxenye ezinamaphoyinti aphansi okubila ziyahwamuka futhi izinsalela zazo zikhishwa phansi kwesi-evaporator.

II. Izici Zokusebenza
•Ukwehla kwengcindezi ye-vacuum okuphansi:
Lapho igesi ephefumulayo yezinto ezisetshenziswayo isuka endaweni yokushisa iye kwi-condenser yangaphandle, kuba khona ingcindezi ethile ehlukile. Ku-evaporator evamile, ukwehla kwengcindezi okunjalo (Δp) kuvame ukuba phezulu, ngezinye izikhathi ngezinga elingamukeleki. Ngokuphambene nalokho, i-Short Path Distillation Machine inesikhala esikhulu segesi, ingcindezi yayo cishe ilingana naleyo eku-condenser; ngakho-ke, kukhona ukwehla kwengcindezi okuncane futhi izinga le-vacuum lingaba yi-≤1Pa.
• Izinga lokushisa lokusebenza eliphansi:
Ngenxa yesici esingenhla, inqubo yokuhwamuka ingenziwa ngezinga eliphezulu le-vacuum. Njengoba izinga le-vacuum likhuphuka, izinga lokubila elihambisanayo lezinto liyancipha ngokushesha. Ngakho-ke, ukusebenza kungenziwa ngezinga lokushisa eliphansi futhi ukubola komkhiqizo kuncishiswe ngaleyo ndlela.
• Isikhathi esifushane sokushisa:
Ngenxa yesakhiwo esiyingqayizivele soMshini Wokucwilisa Wendlela Emfushane kanye nokusebenza kokupompa kwe-applicator yefilimu, isikhathi sokuhlala kwezinto eziku-evaporator sifushane; ngaphezu kwalokho, ukuzulazula okusheshayo kwefilimu ku-evaporator yokushisa kwenza umkhiqizo ungakwazi ukuhlala ebusweni be-evaporator. Ngakho-ke, kufanelekile kakhulu ekushiseni kwezinto ezithinta ukushisa.

• Ukuqina okukhulu kokuhwamuka kwamanzi:
Ukuncipha kwephuzu lokubila kwezinto kwandisa umehluko wokushisa kwezinto ezifudumayo; umsebenzi womshini wokufaka ifilimu wehlisa ukujiya kwefilimu ewuketshezi esimweni esiguquguqukayo futhi wehlisa ukumelana nokushisa. Okwamanje, inqubo icindezela ukugoba nokungcola kwezinto endaweni yokushisa futhi ihambisana nokushintshana okuhle kokushisa, ngaleyo ndlela kwandisa i-coefficient yokudlulisa ukushisa iyonke ye-evaporator.

• Ukuguquguquka okukhulu kokusebenza:
Ngenxa yezakhiwo zayo ezihlukile, i-scraper film evaporator ifanelekela ukwelapha izinto ezizwela ukushisa ezidinga ukuhwamuka okubushelelezi nokuzinzile kanye nezinto ezinokuqina okuphezulu okunokuqina okukhulu okwanda kakhulu ngokwanda kokuhlushwa, njengoba inqubo yayo yokuhwamuka ibushelelezi futhi izinzile.

Ifanele futhi ukuhwamuka kanye nokuhluzwa kwezinto eziqukethe izinhlayiya noma ezimweni zokwakheka kwekristalu, ukwenziwa kwepolymer kanye nokungcoliswa.

III. Izindawo Zokufaka Isicelo
I-evaporator yefilimu yokuskena isetshenziswe kabanzi kumaphrojekthi okushintshanisa ukushisa. Isiza ukushintshanisa ukushisa kwezinto ezithinta ukushisa (isikhathi esifushane) ikakhulukazi, futhi ingakhipha imikhiqizo eyinkimbinkimbi enemisebenzi yayo eyahlukahlukene.
