Ukusetyenziswa koMshini woKusulwa kweFilimu oMfutshane weDistillation

I. Intshayelelo
Itekhnoloji yokwahlula yenye yetekhnoloji ezintathu ezinkulu zokuvelisa imichiza. Inkqubo yokwahlula inempembelelo enkulu kumgangatho wemveliso, ukusebenza kakuhle, ukusetyenziswa kunye nenzuzo. I-TFE Mechanically-agitated Short Path Distillation Machine sisixhobo esisetyenziselwa ukwenza ulwahlulo ngokuguquguquka kwezinto. Esi sixhobo sine-coefficient ephezulu yokudlulisa ubushushu, iqondo lobushushu eliphantsi le-evaporation, ixesha elifutshane lokuhlala lezinto eziphathekayo, ukusebenza kakuhle kwe-thermal kunye nokunyuka okuphezulu kokunyuka. Isetyenziswa ngokubanzi kumashishini ee-petrochemicals, iikhemikhali ezintle, iikhemikhali zezolimo, ukutya, amayeza kunye nobunjineli be-biochemical, ukuqhuba iinkqubo zokunyuka komphunga, ukugxininiswa, ukususwa kwe-solvent, ukucocwa, ukuchithwa kwe-steam, ukukhupha, ukuvumba, njl njl.

I-Short Path Distillation yi-evaporator entsha kwaye esebenzayo enokuthi iqhube ifilimu e-evaporation ewela phantsi kweemeko ze-vacuum, apho ifilimu yenziwe ngenkani sisifakeli sefilimu esijikelezayo kwaye inesantya esiphezulu sokuhamba, ukuhanjiswa kobushushu obuphezulu kunye nexesha elifutshane lokuhlala (malunga 5-15 imizuzwana). Ikwanayo ne-coefficient yokudlulisa ubushushu obuphezulu, amandla aphezulu okuba ngumphunga, ixesha elifutshane lokuhamba kunye nokuguquguquka okukhulu kokusebenza, okulungele ngakumbi ukugxininiswa ngokuphuma komphunga, ukukhupha, ukususwa kwe-solvent, i-distillation kunye nokucocwa kwezixhobo ezithintela ukushisa, izinto eziphezulu ze-viscosity kunye nokulula. ikristale kunye nezixhobo eziqulethwe ngamasuntswana. Iqukethe i-cylinders enye okanye ngaphezulu kunye neebhatyi zokufudumeza kunye ne-applicator yefilimu ejikelezayo kwi-cylinder. Umfaki bhanyabhanya usoloko ekhuhla imathiriyeli yesondlo ibe yifilim elulwelo efanayo kumphezulu wokufudumeza kwaye izityhalele ezantsi, ngelo xesha iinxalenye ezinamaqondo aphantsi abilayo ziba ngumphunga kwaye iintsalela zazo zikhutshwe ezantsi komphunga.

II. Iimpawu zoMsebenzi
•Ukuhla koxinzelelo lwevacuum esezantsi:
Xa i-gas vaporized of the materials transfers ukusuka kwindawo yokufudumala ukuya kwi-condenser yangaphandle, kukho uxinzelelo oluthile oluhlukileyo. Kwi-evaporator eqhelekileyo, ukuhla koxinzelelo (Δp) kudla ngokuba phezulu, ngamanye amaxesha ukuya kwiqondo elingamkelekanga. Ngokwahlukileyo, uMshini oMfutshane weDistillation Machine unendawo enkulu yegesi, uxinzelelo oluphantse lulingane nelo kwi-condenser; ngoko ke, kukho ukuhla koxinzelelo oluncinci kwaye idigri ye-vacuum ingaba ≤1Pa.
• Ubushushu obuphantsi bokusebenza:
Ngenxa yale propati ingentla, inkqubo yokuphuphuma komphunga inokuqhutywa kwiqondo eliphezulu levacuum. Ekubeni idigri ye-vacuum inyuka, indawo yokubilisa ehambelanayo yezinto eziphathekayo iyancipha ngokukhawuleza. Ngoko ke, ukusebenza kunokuqhutyelwa kwiqondo lokushisa eliphantsi kwaye ukuchithwa kwe-thermal yemveliso kuncitshisiwe.
• Ixesha elifutshane lokufudumeza:
Ngenxa yesakhiwo esiyingqayizivele soMshini oMfutshane we-Distillation Machine kunye nesenzo sokupompa sofakelo lwefilimu, ixesha lokuhlala lezinto kwi-evaporator lifutshane; Ukongeza, isiphithiphithi esikhawulezayo sefilimu kwi-evaporator yokufudumala yenza ukuba imveliso ingakwazi ukuhlala kwindawo ye-evaporator. Ngoko ke, ifaneleke ngokukodwa ukuphuphuma kwezinto ezinobushushu obunobushushu.

• Ubushushu obuphezulu bomphunga:
Ukunciphisa indawo yokubilisa yezinto kwandisa ukuhluka kweqondo lokushisa kwimidiya eshushu; umsebenzi wesicelo sefilimu unciphisa ubukhulu befilimu yolwelo kwimeko ephazamisayo kwaye inciphisa ukuxhathisa kwe-thermal. Okwangoku, inkqubo icinezela i-caking kunye ne-fouling yezinto eziphathekayo kwindawo yokufudumeza kwaye ihamba kunye nokutshintshana kobushushu obulungileyo, ngaloo ndlela inyusa i-coefficient yokudlulisa ubushushu be-evaporator.

• Ukuguquguquka okukhulu kokusebenza:
Ngenxa yeempawu zayo ezikhethekileyo, i-evaporator yefilimu ye-scraper ifanelekile ukunyanga izinto ezithintekayo ukushisa ezifuna ukukhupha i-evaporation egudileyo kwaye ezinzileyo kunye nezixhobo eziphezulu ze-viscosity ezine-viscosity ezinyuka kakhulu ngokunyuka koxinzelelo, njengoko inkqubo yokunyuka kwayo ihamba kakuhle kwaye iqinile.

Kwakhona ifanelekile ukukhupha kunye ne-distillation yezinto eziqukethe amaqhekeza okanye kwiimeko ze-crystallization, i-polymerization kunye ne-fouling.
