316L Stainless Steel Spiral Plate Heat Exchanger

Yakhelwe ngokuphelele kusuka-izinga elingu-316L lensimbi engagqwali{2}}kokubili i-spiral plate core negobolondo-le exchanger ikhombisa ukumelana nokugqwala, ama-acids, ama-alkali, ne-chloride{4}}equkethe imidiya (isb, amanzi olwandle, uketshezi lwe-acidic). Ngokushisa okuphezulu kokusebenza kwe-400℃kanye ne-coefficient yokwandisa ukushisa okufanayo, igcina ubuqotho besakhiwo ngaphansi kokushisa okudlulele kanye nokuguquguquka kwengcindezi (kufika ku-2.5 MPa), isusa izingozi zokuguquguquka kanye nesidingo semishini eyengeziwe yokunciphisa ingcindezi. I-316L iphinda ihlangabezane nezindinganiso eziqinile zokuhlanzeka (FDA 21 CFR Part 177, EU GMP), okuyenza ifanelekele ukudla, imithi, kanye{14}}nokusetshenziswa kwamakhemikhali ahlanzekile.

Ifaka-idizayini yokuphela kwesiphetho ehlukanisekayo ehlukile, isishintshi sivumela ukufinyelela okusheshayo kumashaneli agelezayo angaphakathi ngaphandle kokuwahlakaza ngokugcwele. Lokhu kubalulekile ezimweni zokusebenza lapho uhlangothi olulodwa loketshezi luqukethe izinhlayiya ezincane noma izinsalela ze-viscous (isb., i-pulp yesithelo, izinhlawulo ze-catalyst) ezivame ukuvaleka kodwa ezingakhuli. Ama-opharetha angakwazi ukuhlanza ukungcola, intlenga, noma imali enamathelayo eziteshini ezigelezayo esikhathini esingangamahora angu-1–2{8}}okushesha u-80% kunezishintshi{10}ezishiselwe ngokugcwele zamapuleti asontekile. Idizayini iphinde yehlise izindleko zokulungisa ngokugwema ukudilizwa kweyunithi ebizayo kanye nokunciphisa isikhathi sokuphumula sokukhiqiza.

Yamukela ukudluliswa kokushisa kwe-countercurrent (reverse), isishintshi sithuthukisa umehluko wezinga lokushisa phakathi koketshezi olushisayo nolubandayo kuyo yonke indlela yokugeleza. Lo mklamo uthuthukisa kakhulu ukusebenza kahle kokudluliswa kokushisa kanye nokutholwa kwamandla uma kuqhathaniswa nezishintshisi zokushisa ngesikhathi esisodwa. Ngokuvamile, igobolondo lendabuko-kanye{3}}nezishintshi zokushisa zeshubhu zithola i-coefficient yokudlulisa ukushisa engu-1,000–3,000 W/(m²·℃); ngaphansi kwezimo ezithile zokusebenza (isib. Ezinhlelweni zokuthola ukushisa kwemfucuza yezimboni, kukhulisa amazinga okusetshenziswa kabusha kwamandla ngo-35-45%, kunciphisa ukusetshenziswa kukaphethiloli noma isitimu kakhulu.

Ishaneli yokugeleza okuvunguzayo yangaphakathi ye-exchanger yakhiwe ngedizayini ye-arc enwetshiwe, ebushelelezi (ububanzi beshaneli yokugeleza obungu-10–50 mm, enziwa ngendlela oyifisayo) evimbela ukumiswa koketshezi nokunqwabelana kwezinhlayiyana. Lesi sakhiwo "esizisakazayo" siqinisekisa ukugeleza koketshezi okufanayo ngisho nakumidiya enokuqukethwe okuqinile okuphansi (isb., ijusi ene-pulp, i-chemical slurries), ukugwema ngokuphumelelayo ukuvinjelwa. Ngokungafani nokushintshisana kokushisa kwamapuleti anezikhala ezincane (2–5 mm) ezivala njalo, lo mklamo unweba isikhathi esimaphakathi phakathi kokuhlanzwa kusuka evikini elingu-1 kuye kwezinyanga eziyisi-6 ezimeni zokucubungula ukudla. Isakhiwo esiqinile sepuleti elivunguzayo siphinda simelane nokuguga, impilo yesevisi ngo-50% ubude kunokushintshana okujwayelekile okungu-304 kwensimbi engagqwali.

Idizayinelwe ukubekwa okuguquguqukayo, i-exchanger isekela kokubili ukufakwa okuvundlile nokuma mpo, ukuzivumelanisa nezikhala zokusebenzela ezilinganiselwe noma ezingajwayelekile (isb,{2}}izindlu ezihlanzekile zosilingi, amaphaseji amapayipi amancane). Ukufakwa okuqondile konga isikhala saphansi esingafika ku-60% uma kuqhathaniswa namagobolondo avundlile-kanye{6}}nama-tube exchanger, kuyilapho ukufakwa okuvundlile kwenza ukunakekelwa kube lula{7}kuzinhlelo zokusebenza zezimboni ezisindayo. I-compact footprint kanye nedizayini engasindi (30% lightweight kunenye-isheluli lomthamo{11}}kanye{12}namayunithi weshubhu) iphinde yehlise izindleko zengqalasizinda zozimele zosekelo nokulungiswa kwamapayipi.

Umklamo owodwa-okhiphekayo wehlisa inkimbinkimbi yokukhiqiza, unciphisa izindleko zokuqala zokutshalwa kwezimali ngo-15–20% uma kuqhathaniswa-nama-exchange spiral dischable exchanger akabili. Ukusebenza kahle kwayo kokudlulisa ukushisa kwehlisa ukusetshenziswa kwamandla (isb., ukusetshenziswa kwesitimu esingaphansi ngo-15–25% ezinhlelweni zokufudumeza), kuyilapho ukugcinwa okungavamile nempilo ende yesevisi kunciphisa izindleko zokusebenza eziqhubekayo. Ngamazinga okugeleza amancane{{10}kuya{11}}okumaphakathi, inikeza izindleko ezengeziwe{12}}ezihlukile ezisebenzayo{13}}eziphezulu{13}}izishintshi zokushisa ezihlangene (isb, amapuleti{16}}izishintshi zokushisa zeshell) ngaphandle kokudela ukusebenza.
