I-evaporator yefilimu eneziphumo ezithathu

Intshayelelo ngokubanzi

Multi-effect falling film evaporator yamkela umgaqo wokuba umphunga wohlobo lwefilimu. Itshisa isisombululo esinqabileyo sokubilisa
inqaku ukuze ukufuma kubiliswe kude; ngaloo ndlela ifikelela kwinjongo yocondensation. Le yunithi yomatshini ithatha imveliso eqhubekayo. Ineenzuzo zomlinganiselo omkhulu wokujiya (1/5-1/10), umda obanzi we-viscidity (<400CP), isiphumo esihle sokudluliselwa kobushushu kunye nomthamo omkhulu wokusetyenzwa njalo njalo .. Ilungele ukuphuphuma kwezinto ezinobushushu obunobuntununtunu, obuphezulu kwi-consistency, enkulu kwi-viscidity kunye ne-corrosion, ikwafanelekile kwi-condensing corn steep corn, i-insodium ye-monosy yotywala kunye ne-iquor Utywala be-glutamate kwizinto zokutya, ubisi, iswekile kunye ne-lees filtrate.

Le yunithi ine-coefficient enkulu yokudluliselwa kobushushu, ngoko ke umahluko weqondo lobushushu lokudluliselwa kobushushu mncinane. Inokudibanisa ukuze
isiphumo esiphindwe kabini, isiphumo esiphindwe kathathu, isiphumo esine okanye isiphumo esintlanu senkqubo yokumphunga ngokweempawu zezinto eziphuphumayo kunye neenjongo ezahlukeneyo zokumka ngumphunga, kwaye inokusebenzisa umphunga omdaka ngaphezulu kombhobho wombhobho okanye umatshini wokomisa uhlobo lwediski kunye nolunye umthombo wobushushu ophantsi (njengomphunga wamanzi ojiyileyo) ukuze usebenze njengenkunkuma yobushushu bokusebenzisa umphunga, okunciphisa ukusetyenziswa kobushushu bomphunga kakhulu, okunciphisa amandla okusebenzisa umphunga. Ukuba inkunkuma yobushushu bomphunga ibonelelwe ngokwaneleyo, ayifuni nawuphi na umphunga ophilayo, ngaloo ndlela ifumana inzuzo yezoqoqosho ephawulekayo.

Ulwakhiwo kunye nokusebenza

I-evaporator ene-evaporator enye yenziwa ligumbi elinye lokufudumeza kunye negumbi elinye lokwahlula umphunga-ulwelo. Le yunithi ye-evaporator yenziwe ngama-evaporators amabini okanye ngaphezulu, impompo yokufudumala, iimpompo ezahlukeneyo zokutya kunye nokukhupha, isixhobo sokucoca, isixhobo sokuvavanya, umbhobho kunye nevalve. Igumbi lokufudumeza ubukhulu becala liqulunqwe yi-crust, isixhobo sokudibanisa umbhobho kunye nombhobho wokudibanisa. Kwaye igumbi lokwahlula umphunga-ulwelo liqulunqwe yi-crust kunye ne-foam eliminator.

a.Le yunithi yomatshini ityisa imathiriyeli ngokuqhubekayo ezantsi okanye kumlambo onyukayo okanye ekuhambeni okuxutyiweyo. Ukuba ukondla kwi-downstream, i-flow direction of solution iyafana ne-steam ngexesha lokufudumeza. Izinto ezikrwada zifudunyezwa kwindawo yokubilisa nge-pre-heater kwaye emva koko zifikelele kwisiphumo sokuqala. Njengoko indawo yokubilisa yesisombululo kwisiphumo sangaphambili iphezulu kunoko kwisiphumo samva, izinto ziya kuba zishushu kwaye zibe ngumphunga ngokwazo xa zingena kwisiphumo sokugqibela, okwangoku, njengoko amanzi ajikiweyo kwisiphumo sangaphambili anokuthi abe ngumphunga emva kokuza kwisiphumo sokugqibela, umsinga wesibini uya kuveliswa ngakumbi. Ukuba ukondla kwindawo ephezulu, izinto ezikrwada zondliwa kwisiphumo sesithathu. Izinto eziphathekayo zokuqala zikhutshwa ngesiphumo sesibini. Xa usondla izinto ezixubileyo, izinto eziluhlaza zondliwa yinto yesithathu kwaye ikhutshwe yimpembelelo yesibini ngesiphumo sokuqala.

b.Ukuxhomekeka kwisiphumo soxinzelelo lwe-heat-insulation compression, i-steam eject eject heat pump yenza enye i-steam yesibini kwisiphumo sokuqala iphucule ubushushu bayo bokugcwala kwaye ibuyele kwindawo yokuqala yokufudumeza ukuze isebenze njengokufudumala komphunga, ngoko ke, iqondo loqoqosho lokuvelisa umphunga luphuculwe.

c.Iphaneli yokusabalalisa i-static yenza ifom yezinto eziphathekayo zihamba njengefilimu ngokulinganayo nangempumelelo emva kokungena kumbhobho wokutya ukusuka phezulu kwendawo yokufudumeza, ngoko ke i-coefficient yokudluliselwa kobushushu iphuculwe kakhulu; kunye nokulahlekelwa kweqondo lokushisa okubangelwa yi-static-pressure intloko inokushiywa; ngoko ke, umahluko iqondo lobushushu mkhulu kakhulu kwimeko efanayo evaporator ifilimu ewayo.

d.Njengokuba isisombululo sihlala ixesha elifutshane kwi-evaporator, ifaneleke kakhulu ekuphuhliseni imathiriyeli ebuthathaka kubushushu.
