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 kufikelelwa 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 wokulungisa njl. , iphezulu ngokuhambelana, inkulu kwi-viscidity kunye ne-corrosive, ikwalungele ukuxinanisa utywala bombona kunye nothuli lwe-malt kushishino lwesitatshi, isiraphu kunye notywala be-monosodium glutamate ekutyeni, 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 inkqubo yokukhupha umphunga ngokweepropati zezinto eziba ngumphunga kunye neenjongo ezahlukeneyo zokumka zibe ngumphunga, ngokunjalo inokusebenzisa umphunga ongcolileyo kumphezulu wombhobho okanye umatshini wokomisa uhlobo lwediski kunye omnye umthombo wobushushu obuphantsi (ofana nomphunga wamanzi ojiyileyo) ukuba usebenze njengenkunkuma engumphunga wobushushu, ocutha ukusetyenziswa komphunga kakhulu kwaye ufikelele kwisiphumo sokonga amandla. 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 kunesiphumo samva, izinto ziya kuba zishushu kakhulu kwaye zibe ngumphunga ngokwazo xa zingena kwisiphumo sokugqibela, okwangoku, njengoko amanzi ajikiweyo kwisiphumo sangaphambili anokuthi abe ngumphunga emva kokungena kwisiphumo sokugqibela. , umsinga wesibini uya kuveliswa ngakumbi. Ukuba ukondla kwindawo ephezulu, izinto ezikrwada zondliwa kwisiphumo sesithathu. Isixhobo sokuqala sikhutshwa 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 yokufudumeza impompo yenza ukuba umphunga wesibini kwisiphumo sokuqala uphucule ubushushu bawo kwaye ubuyele kwindawo yokuqala yokufudumeza ukuze usebenze njengokufudumala umphunga, ngoko ke, iqondo loqoqosho lokuvelisa umphunga. iyaphuculwa.

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.
