Ukusetyenziswa koMatshini wokuCoca iFilm eWiped Short Path Distillation

I. Intshayelelo
Itekhnoloji yokwahlulahlula yenye yezona teknoloji zithathu ziphambili zokuvelisa iikhemikhali. Inkqubo yokwahlulahlula inempembelelo enkulu kumgangatho wemveliso, ukusebenza kakuhle, ukusetyenziswa kunye nenzuzo. Umatshini we-TFE oshukunyiswa ngoomatshini omfutshane sisixhobo esisetyenziselwa ukwenza ukwahlulahlula ngokusebenzisa ukuguquguquka kwezinto. Esi sixhobo sinomlinganiselo ophezulu wokudlulisa ubushushu, ubushushu obuphantsi bokufuma, ixesha elifutshane lokuhlala kwezinto, ukusebenza kakuhle kobushushu kunye nokuqina okuphezulu kokufuma. Sisetyenziswa kakhulu kumashishini eekhemikhali zepetrochemicals, iikhemikhali ezintle, iikhemikhali zezolimo, ukutya, amayeza kunye nobunjineli be-biochemical, ukuqhuba iinkqubo zokufuma, ukugxila, ukususwa kwe-solvent, ukucoca, ukususa umphunga, ukususa igesi, ukususa ivumba elibi, njl.

I-Short Path Distillation yi-evaporator entsha nesebenzayo enokwenza ukufuma kwefilimu phantsi kweemeko ze-vacuum, apho ifilimu yenziwa ngenkani yi-applicator yefilimu ejikelezayo kwaye inesantya esiphezulu sokuhamba, ukusebenza kakuhle kokudlulisa ubushushu kunye nexesha elifutshane lokuhlala (malunga nemizuzwana emi-5-15). Ikwanayo ne-coefficient ephezulu yokudlulisa ubushushu, amandla aphezulu okufuma, ixesha elifutshane lokuhamba kunye nokuguquguquka okukhulu kokusebenza, okufanelekileyo ngokukodwa kuxinzelelo ngokufuma, ukususa igesi, ukususa i-solvent, ukucocwa kunye nokucocwa kwezinto ezinobushushu, izinto ezinobuthi obukhulu kunye nezinto eziqulathe iikristale ezilula kunye namasuntswana. Iqulethe isilinda esinye okanye ngaphezulu esineejakethi zokufudumeza kunye ne-applicator yefilimu ejikelezayo kwisilinda. I-applicator yefilimu isoloko ikrwela izinto zokutya kwifilimu yolwelo efanayo kumphezulu wokufudumeza kwaye izityhalele ezantsi, apho izinto ezinamaqondo aphantsi okubila ziyanyamalala kwaye iintsalela zazo zikhutshwa ezantsi kwe-evaporator.

II. Iimpawu Zokusebenza
•Uxinzelelo oluphantsi lwe-vacuum cleaner:
Xa igesi ephefumulayo yezinto ezisetyenziswayo isuka kumphezulu wobushushu iye kwi-condenser yangaphandle, kukho uxinzelelo oluthile lomahluko. Kwi-evaporator eqhelekileyo, ukuhla koxinzelelo olunjalo (Δp) kudla ngokuba phezulu, ngamanye amaxesha ukuya kwinqanaba elingamkelekanga. Ngokwahlukileyo koko, i-Short Path Distillation Machine inendawo enkulu yegesi, uxinzelelo lwayo luphantse lulingane nolo lukwi-condenser; ngoko ke, kukho ukuhla koxinzelelo oluncinci kwaye i-vacuum degree ingaba yi-≤1Pa.
• Ubushushu obuphantsi bokusebenza:
Ngenxa yeempawu ezingentla, inkqubo yokuphuma komoya inokwenziwa kwiqondo eliphezulu le-vacuum. Ekubeni iqondo le-vacuum lisanda, iqondo lokubila elifanelekileyo lezinto liyancipha ngokukhawuleza. Ke ngoko, umsebenzi unokwenziwa kwiqondo lobushushu eliphantsi kwaye ukubola kobushushu bemveliso kuncitshiswe ngaloo ndlela.
• Ixesha elifutshane lokufudumeza:
Ngenxa yesakhiwo esahlukileyo seShort Path Distillation Machine kunye nokusebenza kokumpompa kwesixhobo sokufaka ifilimu, ixesha lokuhlala kwezinto kwi-evaporator lifutshane; ukongeza, ukuxinana ngokukhawuleza kwefilimu kwi-evaporator yokufudumeza kwenza imveliso ingakwazi ukuhlala kumphezulu we-evaporator. Ke ngoko, ifanelekile ngokukodwa ekuphumeni kwezixhobo ezinobushushu.

• Ubushushu obuphezulu bokufuma:
Ukuncipha kweqondo lokubila kwezinto kwandisa umahluko kubushushu bezinto ezishushu; umsebenzi wesixhobo sokufaka ifilimu unciphisa ubukhulu befilimu engamanzi kwimeko yokuxinana kwaye kunciphisa ukumelana nobushushu. Okwangoku, le nkqubo ithintela ukugqunywa kunye nokungcola kwezinto kumphezulu wobushushu kwaye ihamba kunye nokutshintshiselana kobushushu okuhle, ngaloo ndlela kwandisa i-coefficient iyonke yokudlulisa ubushushu ye-evaporator.

• Ukuguquguquka okukhulu kokusebenza:
Ngenxa yeempawu zayo ezikhethekileyo, i-scraper film evaporator ifanelekile ukunyanga izinto ezibuthathaka kubushushu ezifuna ukufuma okuthambileyo nokuzinzileyo kunye nezinto ezinobungqindilili obuphezulu ezibungqindilili obunyuka kakhulu ngokwanda koxinzelelo, njengoko inkqubo yayo yokufuma ithambile kwaye izinzile.

Ikwafanelekile ekutshiseni nasekukhupheni izinto eziqulethe amasuntswana okanye xa kukho i-crystallization, polymerization kunye ne-fouling.

III. Iindawo zokusetyenziswa
I-evaporator yefilimu yokukrazula isetyenziswa kakhulu kwiiprojekthi zokutshintshiselana ngobushushu. Inceda ukutshintshiselana ngobushushu kwezinto ezibuthathaka kubushushu (ixesha elifutshane) ngakumbi, kwaye inokunyibilikisa iimveliso ezintsonkothileyo ngemisebenzi yayo eyahlukeneyo.
