Kushandiswa kweMuchina weWiped Film Short Path Distillation Machine

I. Nhanganyaya
Tekinoroji yekuparadzanisa ndeimwe yetekinoroji nhatu huru dzekugadzira makemikari. Maitiro ekuparadzanisa ane simba guru pamhando yezvigadzirwa, kushanda zvakanaka, kushandiswa uye mabhenefiti. Muchina weTFE Mechanically-agitated Short Path Distillation Machine mudziyo unoshandiswa kuita kuparadzanisa kuburikidza nekushanduka kwezvinhu. Mudziyo uyu une coefficient yepamusoro yekufambisa kupisa, tembiricha yakaderera ye evaporation, nguva pfupi yekugara kwezvinhu, kushanda zvakanaka kwekupisa uye simba re evaporation. Unoshandiswa zvakanyanya mumaindasitiri e petrochemicals, makemikari akanaka, makemikari ekurima, chikafu, mishonga uye biochemical engineering, kuita maitiro e evaporation, concentration, solvent removal, kuchenesa, steam stripping, degassing, deodorization, etc.

Short Path Distillation imuchina mutsva uye unoshanda zvakanaka we evaporator unogona kuita evaporation yefirimu inodonha pasi pemamiriro e vacuum, umo firimu rinogadzirwa nechisimba ne rotating film applicator uye rine kumhanya kukuru kwekuyerera, kushanda kwakanyanya kwekupisa uye nguva pfupi yekugara (anenge masekondi mashanu kusvika gumi nemashanu). Inewo coefficient yepamusoro yekufambisa kupisa, simba guru rekubuda kwemhepo, nguva pfupi yekuyerera uye kuchinjika kukuru kwekushanda, izvo zvakakodzera kunyanya kuunganidzwa nekubuda kwemhepo, kubvisa gasi, kubvisa solvent, distillation uye kuchenesa zvinhu zvinonzwa kupisa, zvinhu zvine viscosity yakawanda uye zvinhu zviri nyore zvine crystal uye particle-containing. Ine silinda imwe kana kupfuura ine majaketi ekudziisa uye firimu applicator inotenderera mu silinda. Firimu applicator inogara ichikwesha zvinhu zvekudyisa kuita firimu remvura rakafanana pamusoro pekupisa uye ichizvisundira pasi, panguva iyo zvikamu zvine nzvimbo shoma dzekufashaira zvinopera uye zvasara zvadzo zvinoburitswa kubva pasi pe evaporator.

II. Hunhu hweKushanda
•Kudzikira kwemhepo inotonhorera pasi:
Kana gasi rakapfava rezvinhu izvi richibva pamusoro pekupisa richienda kune condenser yekunze, pane imwe pressure yakasiyana. Mu evaporator yakajairika, pressure drop (Δp) yakadaro inowanzo kwira zvakanyanya, dzimwe nguva kusvika padanho risingagamuchirwi. Kusiyana neizvi, Short Path Distillation Machine ine nzvimbo yakakura yegesi, iyo pressure yayo inenge yakaenzana neiri mu condenser; saka, pane pressure drop diki uye vacuum degree inogona kuva ≤1Pa.
• Tembiricha yakaderera yekushanda:
Nekuda kwehunhu hwataurwa pamusoro apa, maitiro ekubuda kwemvura anogona kuitwa padanho repamusoro re vacuum. Sezvo dhigirii re vacuum richikwira, poindi yekufashaira yezvinhu inoderera nekukurumidza. Nokudaro, kushanda kunogona kuitwa patembiricha yakaderera uye kuora kwekupisa kwechigadzirwa kunoderedzwa.
• Nguva pfupi yekupisa:
Nekuda kwechimiro chakasiyana cheMuchina weShort Path Distillation uye kushanda kwemuchina wekushandisa firimu, nguva yekugara kwezvinhu zviri mu evaporator ipfupi; pamusoro pezvo, kutenderera nekukurumidza kwefirimu mu heating evaporator kunoita kuti chigadzirwa chisakwanise kugara pamusoro pe evaporator. Saka, inonyanya kukodzera kupiswa kwezvinhu zvinopisa.

• Kuwanda kwemvura inobuda mumhepo:
Kudzikira kwekupisa kwezvinhu kunowedzera musiyano wekupisa kwemidziyo inopisa; basa remuchina wekuisa firimu rinoderedza ukobvu hwefirimu remvura kana raoma uye rinoderedza kuramba kupisa. Panguva iyi, maitiro aya anoderedza kuvharika uye kusvibiswa kwezvinhu pamusoro pekupisa uye anoperekedzwa nekuchinjana kwakanaka kwekupisa, nokudaro zvichiwedzera chiyero chekupisa chemuchina we evaporator.

• Kuchinjika kukuru kwekushanda:
Nekuda kwehunhu hwayo hwakasiyana, muchina wekubvisa ngura wakakodzera kurapa zvinhu zvinonzwa kupisa zvinoda kupwa kwakadzikama uye kwakadzikama uye zvinhu zvine viscosity yakawanda izvo viscosity inowedzera zvakanyanya nekuwedzera kwehuwandu, sezvo maitiro ayo ekupwa kwakadzikama uye kwakadzikama.

Yakakodzerawo kubudiswa kwemvura uye kunyungudutswa kwezvinhu zvine zvidimbu kana kana paine crystallization, polymerization uye fouling.

III. Nzvimbo dzeKushandisa
Muchina wekubvisa jira remafirimu wave uchishandiswa zvakanyanya mumapurojekiti ekuchinjana kupisa. Unobatsira kuchinjana kupisa kwezvinhu zvinonzwa kupisa (kwenguva pfupi), uye unogona kunyungudutsa zvigadzirwa zvakaoma zvine mabasa akasiyana-siyana.
Muchina wekubvisa tsvina uchishandisa evaporator wave uchishandiswa pakubvisa tsvina, kubvisa zvinonyungudutsa, kubvisa utsi, kuita chimwe chinhu, kubvisa mweya, kubvisa kunhuhwirira (de-aeration), nezvimwewo munzvimbo dzinotevera, uye wakawana mhedzisiro yakanaka:
