316L Stainless Steel Spiral Plate Heat Exchanger

E entsoe ho tsoa ho{{0}grade 316L stainless steel-ka bobeli spiral plate core le khetla-kana sena se bontša ho hanyetsa ho bola, acid, alkalis, le chloride{4}e nang le media (mohlala, metsi a leoatle, maro a acidic). Ka mocheso o phahameng oa ts'ebetso oa 400℃le coefficient e tšoanang ea ho atolosa mocheso, e boloka botšepehi ba sebopeho tlas'a mocheso o feteletseng le ho fetoha ha khatello (ho fihlela ho 2.5 MPa), ho felisa likotsi tsa deformation le tlhokahalo ea lisebelisoa tse eketsehileng tsa ho fokotsa khatello. Thepa ea 316L e boetse e kopana le litekanyetso tse thata tsa bohloeki (FDA 21 CFR Part 177, EU GMP), e etsang hore e tšoanelehe bakeng sa lijo, meriana, le{14}litšebeliso tse phahameng tsa lik'hemik'hale tse hloekileng.

E na le-moaho o mong o ikhethileng oa sekoahelo sa ho qetela, mochine o lumella batho ho kena kapele ho likanale tsa phallo ea kahare ntle le ho qhaqhoa ka botlalo. Sena se bohlokoa bakeng sa maemo a ts'ebetso moo karolo e 'ngoe ea mokelikeli e nang le likaroloana tse nyane kapa masalla a viscous (mohlala, makhasi a litholoana, likotlo tsa catalyst) tse atisang ho thibeloa empa eseng ho hola. Basebelisi ba ka hloekisa litšila, sediment, kapa li-depositi tse khomaretsang lichacheng ka mor'a lihora tse 1–2{8}}80% ka potlako ho feta{10}lichelete tsa khale tsa ho fapanyetsana li-spiral plate. Moralo o boetse o fokotsa litšenyehelo tsa tlhokomelo ka ho qoba ho putlama ha li-unit tse theko e phahameng le ho fokotsa nako ea tlhahiso.

Ho amohela phetiso ea mocheso oa countercurrent (reverse), exchanger e ntlafatsa phapang ea mocheso pakeng tsa maro a chesang le a batang ho pholletsa le tsela eohle ea phallo. Moralo ona o ntlafatsa haholo ts'ebetso ea phetisetso ea mocheso le ho hlaphoheloa ha matla ha ho bapisoa le li-exchange exchange tsa mocheso ka nako e le 'ngoe. Ka tloaelo, likhetla tsa khale-le{3}}li-tube heat exchangers li fumana li-coefficient tsa 1,000–3,000 W/(m²·℃); tlas'a maemo a itseng a ts'ebetso (mohlala, -ho fapanyetsana mocheso oa metsi), 316L spiral plate exchanger e fihla ho coefficient ea ho fetisetsa mocheso ho fihla ho 5,000 W/(m²·℃) -ntlafatso ea 20–30%. Ts'ebetsong ea ho khutlisa litšila tsa indasteri, e eketsa sekhahla sa tšebeliso ea matla ka 35-45%, e fokotsa tšebeliso ea mafura kapa mouoane haholo.

Mocha oa phallo ea spiral oa kahare o entsoe ka moralo o atolositsoeng, o boreleli oa arc (bophara ba kanale ea 10-50 mm, e ka khonehang) e thibelang ho putlama ha mokelikeli le ho bokellana ha likaroloana. Sebopeho sena sa "ho itšebetsa"{3}} se netefatsa phallo ea mokelikeli o ts'oanang le bakeng sa mecha ea litaba e nang le litaba tse tiileng tse tlase (mohlala, lero le nang le makhasi, li-slurries tsa lik'hemik'hale), ho qoba ho thibela ka nepo. Ho fapana le lisebelisoa tsa mocheso oa poleiti tse nang le likheo tse moqotetsane (2-5 mm) tse koalang khafetsa, moralo ona o eketsa nako e tloaelehileng pakeng tsa ho hloekisa ho tloha ho beke e le 'ngoe ho ea ho likhoeli tse 6 maemong a ho lokisa lijo. Sebopeho se matla sa spiral plate se boetse se hanana le ho taboha, ka bophelo ba ts'ebeletso bo bolelele ba 50% ho feta li-exchange 304 tse tloaelehileng tsa tšepe.

E etselitsoe hore e behoe ka mokhoa o fapaneng, mochini o tsamaisang thepa o ts'ehetsa ho tsepama le ho otloloha, ho ikamahanya le libaka tse lekantsoeng kapa tse sa tloaelehang (mohlala,{2}}liphaposi tse hloekileng tsa siling, liphaseje tse tšesaane). Ho kenya ka ho otloloha ho baballa sebaka sa fatše ka 60% ha ho bapisoa le khetla e tšekaletseng-le-li-tube exchangers, ha tse tšekaletseng li nolofatsa tlhokomelo ea{7}}lisebelisoa tse boima tsa indasteri. The compact footprint and lightweight design (30% lightweight than same{{10}capacity shell{11}}le{12}tube units) e boetse e fokotsa litšenyehelo tsa meralo bakeng sa liframe tsa tšehetso le ho lokisa lipompo.

Moralo o le mong-o ka ntshuwang o fokotsa ho rarahana ha tlhahiso, o fokotsa ditjeho tsa matsete ka 15–20% ha o bapisoa le -ka mahlakoreng a mabeli a fapanyetsanang a phunyang. Bokhoni ba eona bo phahameng ba ho fetisa mocheso bo theola tšebeliso ea matla (mohlala, tšebeliso ea mouoane ka tlase ho 15-25% lits'ebetsong tsa ho futhumatsa), athe tlhokomelo e sa tloaelehang le bophelo bo bolelele ba ts'ebeletso e fokotsa litšenyehelo tse tsoelang pele tsa ts'ebetso. Bakeng sa lireiti tse nyane{{10}ho{11}}tse mahareng, e fana ka litjeho tse ngata-tse ling tse sebetsang hantle ho feta{13}}li-firm compact heat exchangers (mohlala, plate{16}}shell heat exchangers) ntle le ho tela ts'ebetso.
