I-Multi-effect falling evaporator yefilimu isebenzisa isimiso sokuhwamuka kohlobo lwefilimu. Ishisa isixazululo esingavamile ekubiliseni
iphuzu ukuze umswakama othile ubiliswe; ngaleyo ndlela ifinyelele inhloso yokufingqa. Le yunithi yomshini isebenzisa ukukhiqizwa okuqhubekayo. Inezinzuzo zesilinganiso esikhulu sokujiya (1/5-1/10), ububanzi be-viscidity (<400CP), umphumela omuhle wokudlulisa ukushisa nomthamo omkhulu wokucubungula njll. Ifanele ukuhwamuka kwezinto ezibonakalayo ezizwela ukushisa. , iphakeme ngokungaguquguquki, i-viscidity enkulu futhi iyagqwala, futhi ifanele ukujiya utshwala obuwummbila nothuli lwe-malt embonini yesitashi, isiraphu notshwala be-monosodium glutamate ekudleni, ubisi, ushukela kanye ne-lees filtrate.
Le yunithi ine-coefficient enkulu yokudlulisa ukushisa, ngakho umehluko wezinga lokushisa wokudlulisa ukushisa mncane. Ingase ihlangane ukuze
i-dual-effect, i-triple-effect, emine noma i-five-effect system yokuhwamuka ngokwezakhiwo zezinto ezihwamukayo kanye nezinjongo ezihlukene zokuhwamuka, futhi ingase isebenzise umhwamuko ongaphezulu kwenqwaba yamapayipi noma umshini wokomisa uhlobo lwediski futhi omunye umthombo wokushisa ophansi (njengomhwamuko wamanzi ojiyile) ozosebenza njengesihwamuli sokushisa esiwudoti, esinciphisa ukusetshenziswa kwesitimu kakhulu futhi sifinyelele umphumela wokonga amandla. Uma imfucumfucu yokushisa inikezwa ngokwanele, ayidingi isitimu esiphilayo, ngaleyo ndlela ithola inzuzo eyongayo emangalisayo.
I-evaporator enomphumela owodwa yenziwa igumbi lokushisisa elilodwa kanye negumbi elihlukanisayo eliwuketshezi oluwuketshezi. Le yunithi ye-evaporator yakhiwa izikhiqizo ezimbili noma ngaphezulu, iphampu yokushisa, amaphampu ahlukahlukene okuphakela nokukhipha, idivayisi yevacuum, ithuluzi lokuhlola, ipayipi kanye nevalvu. Igumbi lokushisisa lakhiwe kakhulu ngoqweqwe, ithuluzi lokuhlanganisa amapayipi kanye nepayipi lokuxhuma. Futhi igumbi lokuhlukanisa elingu-vapor-liquid lakhiwa yi-crust kanye ne-foam eliminator.
a.Le yunithi yomshini iphakela okubalulekile ngokuqhubekayo phansi komfula noma enhla nomfula noma ngokugeleza okuxubile. Uma ukuphakela ezansi nomfula, indlela yokugeleza kwesisombululo iyafana naleyo yesitimu ngesikhathi sokushisa. I-Raw material ishiselwa ngaphambi kokubilisa i-pre-heater bese ifinyelela kumphumela wokuqala. Njengoba indawo yokubilisa yesisombululo emphumeleni wangaphambili iphakeme kunaleyo eyenzeka kamuva, impahla izoshisa ngokweqile futhi ihwamuke iyodwa uma ingena emphumeleni wakamuva, okwamanje, njengoba amanzi ajiyile abesemphumela wangaphambili nawo angahwamuka ngemva kokungena emphumeleni wakamuva. , ukusakaza kwesibili kuzokhiqizwa okwengeziwe. Uma ukondla enhla nomfula, impahla eluhlaza inikezwa umphumela wesithathu. Impahla yomphumela wokuqala ikhishwa ngomphumela wesibili. Lapho uphakela izinto ezixubile, izinto ezingavuthiwe zondliwa yizinto ezinomphumela wesithathu futhi zikhishwa umphumela wesibili ngomphumela wokuqala.
b.Ngokuncika kumthelela wokucindezelwa kwe-heat-insulation, iphampu yokushisisa ye-steam eject yenza isitimu sesibili ekuqaleni sithuthukise izinga lokushisa laso bese sibuyela egumbini lokushisisa lomphumela wokuqala ukuze sisebenze njengesifudumezi, ngaleyo ndlela, izinga lezomnotho lokukhiqiza isitimu. ithuthukisiwe.
c.Iphaneli yokusabalalisa emile yenza izinto ezibonakalayo zigeleze njengefilimu ngokulinganayo nangempumelelo ngemva kokungena epayipini lokuphakela lisuka phezulu kwendawo yokushisisa, ngakho-ke i-coefficient yokudlulisa ukushisa iba ngcono kakhulu; kanye nokwehla kwezinga lokushisa okubangelwa yi-static-pressure head kungase kukhishwe; ngakho-ke, umehluko wokushisa womphumela mkhulu kakhulu esimweni se-evaporator yefilimu efanayo ewayo.
d.Njengoba isixazululo sihlala isikhathi esifushane ku-evaporator, ifaneleka kakhulu ekuhwamukeni kwezinto ezizwela ukushisa.
