I. Isingeniso
Ubuchwepheshe bokuhlukanisa bungobunye bobuchwepheshe obuthathu bokukhiqiza amakhemikhali. Inqubo yokuhlukanisa inomthelela omkhulu kukhwalithi yomkhiqizo, ukusebenza kahle, ukusetshenziswa kanye nenzuzo. I-TFE Mechanically-agitated Short Path Distillation Machine iyisisetshenziswa esisetshenziselwa ukwehlukanisa ngokushintshashintsha kwezinto. Le divayisi ine-coefficient yokudlulisa ukushisa okuphezulu, izinga lokushisa eliphansi lokuhwamuka, isikhathi esifushane sokuhlala sezinto ezibonakalayo, ukusebenza kahle okuphezulu kokushisa kanye namandla aphezulu okuhwamuka. Isetshenziswa kabanzi ezimbonini zamakhemikhali e-petrochemicals, amakhemikhali amahle, amakhemikhali ezolimo, ukudla, umuthi kanye nobunjiniyela be-biochemical, ukwenza izinqubo zokuhwamuka, ukugxilisa ingqondo, ukususwa kwe-solvent, ukuhlanzwa, ukukhumula isitimu, ukukhipha umoya, ukuqeda iphunga, njll.
I-Short Path Distillation iyi-evaporator entsha nesebenza kahle engakwazi ukukhipha ukuhwamuka kwefilimu ngaphansi kwezimo ze-vacuum, lapho ifilimu yenziwa ngenkani isifakeli sefilimu esizungezayo futhi inesivinini sokugeleza okuphezulu, ukusebenza kahle kokudlulisa ukushisa kanye nesikhathi esifushane sokuhlala (cishe. 5-15 imizuzwana). Ibuye ibe ne-coefficient yokudlulisa ukushisa okuphezulu, amandla aphezulu okuhwamuka, isikhathi esifushane sokugeleza kanye nokuguquguquka okukhulu kokusebenza, okulungele ikakhulukazi ukugxila ngokuhwamuka, ukukhipha umoya, ukususwa kwe-solvent, i-distillation kanye nokuhlanzwa kwezinto ezingezwani nokushisa, izinto ezibonakalayo eziphezulu ze-viscosity futhi kulula. ikristalu nezinto ezinezinhlayiyana. Iqukethe isilinda esisodwa noma ngaphezulu anamajakhethi okushisa kanye nesisetshenziswa sefilimu esizungeza kusilinda. Isisebenzi sefilimu siqhubeka nokukhuhla izinto zokuphakelayo zibe ifilimu ewuketshezi efanayo endaweni yokushisisa bese iziphushela phansi, lapho izingxenye ezinamaphoyinti aphansi abilayo ziyahwamuka futhi izinsalela zazo zikhishwe ngaphansi kwesihwamuko.
II. Izimpawu Zokusebenza
•Ukwehla komfutho we-vacuum ophansi:
Lapho igesi ehwamukile yezinto zokwakha idluliswa isuka endaweni yokushisa iye ku-condenser yangaphandle, kuba khona ingcindezi ethile ehlukile. Ku-evaporator evamile, ukwehla kwengcindezi okunjalo (Δp) ngokuvamile kuba phezulu, ngezinye izikhathi kuya ezingeni elingamukeleki. Ngokuphambene, Umshini Omfushane we-Distillation Machine unendawo enkulu yegesi, ukucindezela okucishe kulingane nalokho ku-condenser; ngakho-ke, kukhona ukwehla kwengcindezi encane futhi i-vacuum degree ingaba ≤1Pa.
• Izinga lokushisa eliphansi lokusebenza:
Ngenxa yalesi sakhiwo esingenhla, inqubo yokuhwamuka ingenziwa nge-vacuum degree ephezulu. Njengoba idigri ye-vacuum ikhula, iphuzu lokubilisa elihambisanayo lezinto ezibonakalayo lehla ngokushesha. Ngakho-ke, ukusebenza kungenziwa ekushiseni okuphansi futhi ukubola okushisayo komkhiqizo kuncishisiwe.
• Isikhathi esifushane sokushisisa:
Ngenxa yesakhiwo esiyingqayizivele soMshini Wokukhipha Indledlana emfushane kanye nesenzo sokumpompa isifaki sefilimu, isikhathi sokuhlala sezinto eziku-evaporator sifushane; ngaphezu kwalokho, isiphithiphithi esisheshayo sefilimu ku-evaporator yokushisa kwenza umkhiqizo ungakwazi ukuhlala endaweni ye-evaporator. Ngakho-ke, ifaneleka ngokukhethekile ukuhwamuka kwezinto ezizwela ukushisa.
• Amandla okuhwamuka okuphezulu:
Ukwehliswa kwendawo yokubilisa yezinto kwandisa umehluko wokushisa wemidiya eshisayo; umsebenzi wokufaka isicelo sefilimu wehlisa ukushuba kwefilimu ewuketshezi esimweni esinesiyaluyalu futhi wehlise ukumelana nokushisa. Phakathi naleso sikhathi, inqubo icindezela i-caking kanye nokungcoliswa kwezinto endaweni yokushisa futhi ihambisana nokushintshaniswa okuhle kokushisa, ngaleyo ndlela ikhulise i-coefficient yokudlulisa ukushisa okuphelele kwe-evaporator.
• Ukuguquguquka okukhulu kokusebenza:
Ngenxa yezakhiwo zayo eziyingqayizivele, i-evaporator yefilimu ye-scraper ifaneleka ekwelapheni izinto ezizwela ukushisa ezidinga ukuhwamuka okubushelelezi futhi okuzinzile kanye nezinto ezine-viscosity ephezulu okubonakala kwayo kwanda kakhulu ngokunyuka kokugxila, njengoba inqubo yayo yokuhwamuka ibushelelezi futhi iqinile.
Ibuye ifanele ukuhwamuka kanye ne-distillation yezinto eziqukethe izinhlayiya noma ezimweni ze-crystallization, i-polymerization kanye ne-fouling.
III. Izindawo Zokufaka Isicelo
I-evaporator yefilimu ye-scraper isetshenziswe kabanzi kumaphrojekthi wokushintshanisa ukushisa. Isiza ukushintshaniswa kokushisa kwezinto ezizwela ukushisa (isikhathi esifushane) ikakhulukazi, futhi ingakhipha imikhiqizo eyinkimbinkimbi ngemisebenzi yayo ehlukahlukene.
I-evaporator yefilimu ye-scraper isetshenziselwe ukugxilisa ingqondo ngokuhwamuka, ukususwa kwe-solvent, i-steam-stripping, ukusabela, ukukhipha umoya, ukukhipha iphunga (ukukhipha umoya), njll. ezindaweni ezilandelayo, futhi izuze imiphumela emihle:
