I. Ukuqhathanisa Ukusebenza kahle Kokushintshana Kokushisa: Izishintshi Zokushisa Ze-Plate Zinikeza Izinzuzo Ezibalulekile
1. I-Plate Heat Exchanger: Ukusebenza kahle Kokushintshanisa Ukushisa Okuphezulu
Isishintshi sokushisa kwepuleti sisebenzisa isakhiwo sepuleti likathayela, esivumela uketshezi olungaphakathi kwamashaneli amancane ukuthi lukhiqize{0}}isiyaluyalu esiphezulu ngisho nasezinambeni eziphansi ze-Reynolds, ngaleyo ndlela sisuse ngokuphelele izinkinga ezihlobene nokudlula uketshezi kanye nokuma. igobolondo-kanye-nezishintshi zokushisa zeshubhu. Ngaphezu kwalokho, imidiya ebandayo neshisayo igeleza ngendlela ephikisayo{10}yamanje kuyo yonke inqubo, okuholela ekusetshenzisweni okuphezulu kakhulu kokuhluka kwezinga lokushisa; umehluko wezinga lokushisa eligcinakele lingaba phansi njengedigri engu-1, okuqinisekisa ukushintshaniswa kokushisa okuphelele kakhulu. Ngaphansi kwezimo zokusebenza ezifanayo, lokhu kuhumusha ukunciphisa ukusetshenziswa kwamandla kanye nokulahlekelwa ukushisa okuncane.
2. I-Shell-kanye-Ne-Tube Heat Exchanger: Ukusebenza kahle kokushintshisana kokushisa kumaphakathi kuya kokuphansi.
Kugobolondo-kanye{1}}nezishintshi zokushisa zamashubhu, uketshezi lugeleza ngokuhlukene ohlangothini lweshubhu kanye nohlangothi lwegobolondo; ngenxa yalokho, ukuxubana kwezinxushunxushu kubuthaka, okuholela ekwakhekeni kwezindawo ezifile eziwuketshezi kanye nemigudu yokudlula. Njengomphumela walokho, i-coefficient yokudlulisa ukushisa ngokuvamile isukela ku-300 ukuya ku-1000 W/(m²·℃kuphela). Ukusebenza kahle kokusetshenziswa komehluko wezinga lokushisa phakathi kwemidiya eshisayo nebandayo kukhawulelwe, ngomehluko ovamile wokushisa ogcina ukushisa ongaphezu kuka-5 degrees . Ukuze kuhlangatshezwane nezidingo ezilinganayo zokudlulisa ukushisa, indawo engaphezulu yokudlulisa ukushisa iyadingeka, okuholela ekusetshenzisweni kwamandla okuphezulu uma kuqhathaniswa nezishintshisi zokushisa zamapuleti.
II. Ukuqhathaniswa Kwesakhiwo kanye Nezinyathelo Zokuhamba: Izishintshi Zokushisa Ze-Plate Zihlangene Kakhulu Futhi Zingasindi
1. I-Plate Heat Exchanger: Usayizi ohlangene, ongasindi, kanye nokunyathelisa okuncane.
Izishintshi zokushisa ze-Plate zifaka isakhiwo esiminyene kakhulu, esinendawo yokushintshisana yokushisa ngeyunithi ngayinye esukela ku-200 ukuya ku-1000 m²/m³-edlula kude leyo yegobolondo{3}}kanye{4}}nezisetshenziswa zeshubhu. Ngobukhulu bepuleti obungu-0.4 kuya ku-0.8 mm nje kuphela, isisindo sawo sisonke sicishe sibe-ingxenye yesihlanu yegobolondo-kanye{10}}nesishintshi sokushisa seshubhu sokucaciswa okufanayo. Azidingi indawo enkulu yokufaka, zifaneleka kahle izimboni, izakhiwo, kanye{12}}namaphrojekthi ezimboni amancane lapho isikhala silinganiselwe; ngaphezu kwalokho, zibandakanya izindleko eziphansi zokuhamba nezokufaka, ezinikeza izinzuzo ezihlukile zokuthumela phesheya kwezilwandle.
2. I-Shell-kanye-Ne-Tube Heat Exchanger: Ivolumu enkulu, i-bulky, futhi ithatha indawo enkulu.
IShell-kanye{1}}nezishintshi zokushisa zeshubhu{2}}zihlanganisa{2}}izingxenye ezisindayo{3}}njengegobolondo, ishubhu bundle, ishubhu sheet, nama-baffles{4}}okuholela esakhiweni esikhulu nesishubile esinendawo yokushintshisana yokushisa engu-50–150 m²/m³ kuphela. Ngaphansi kwamapharamitha okushintshanisa ukushisa afanayo, ivolumu yawo ebonakalayo kanye nokugxilwa kwawo kukhulu ngokuphindwe kaningana kunalezo zamapuleti{8}}zokushintshanisa ukushisa kohlobo; ngaphezu kwalokho, zidinga ukufakwa kwezisekelo ezinkulu, ezingaguquki, okuholela ezindlekweni eziphakeme zokuthutha, ukuphakamisa, kanye nokufakwa. Ngenxa yalokho, azifaneleki izimo zephrojekthi ezinezingqinamba zendawo ezilinganiselwe noma ezihlangene.
III. Ukuqhathaniswa kokuguquguquka kwesimo sokusebenza: I-Shell-kanye{2}}ne-Tube Heat Exchangers Ifanele Izimo Zokusebenza Ezidlulele
1. I-Plate Heat Exchanger: Ifanele izimo zokusebenza ezijwayelekile, ezithambile.
Ngenxa yemikhawulo ebekwe ama-gaskets kanye nezakhiwo zamapuleti, izishintshisi zokushisa zamapuleti zinokumelana okulinganiselwe kumazinga okushisa aphezulu nezingcindezi. Amapharamitha wabo okusebenza ajwayelekile akhawulelwe emazingeni okushisa Angaphansi noma alingana no-180℃kanye nezingcindezi Ezingaphansi noma ezilingana no-2.5 MPa. Ngakho-ke, afaneleka kuphela uketshezi oluhlanzekile-njengamanzi ahlanzekile, uwoyela, kanye{5}}nemidiya yamakhemikhali engagqwali{6}}okuvamile{6}}futhi zifaneleka kangcono izimo zokusebenza ezithambile ezitholakala kumasistimu e-HVAC, izinhlelo zokushisisa amanzi, imboni ekhanyayo, ukucutshungulwa kokudla, kanye nemikhakha yezimboni ezivamile. Azifanelekele izindawo eziyingozi kakhulu ezifaka amazinga okushisa aphezulu, ukucindezela okukhulu, noma izinto ezigqwala kakhulu. Ngaphezu kwalokho, imigudu yabo yokugeleza emincane ijwayele ukuvaleka; ngakho-ke, ukusetshenziswa kwemidiya equkethe izinhlayiya ezinkulu noma amazinga aphezulu okungcola akuvunyelwe ngokuqinile.
2. I-Shell-kanye-Ne-Tube Heat Exchanger: Ifanele izimo zokusebenza eziyinkimbinkimbi ezihlanganisa amazinga okushisa aphezulu nezingcindezi eziphezulu.
Igobolondo-kanye-nomshini wokushisa weshubhu uhlanganisa{2}}isakhiwo sensimbi esiqinile futhi esizinzile, esiziqhayisa ngokumelana okukhethekile kukho kokubili ukucindezela okuphezulu kanye nezinga lokushisa eliphezulu; iyakwazi ukumelana nezimo zokusebenza ezingaphezu kuka-400℃kanye ne-10 MPa. Ngenxa yalokho, imele ukhetho olukhethwayo ezimbonini ezinzima ezifana ne-petroleum, ubunjiniyela bamakhemikhali, amandla kagesi, i-metallurgy, namandla enuzi. Izinto zokusebenza zibonakala ngamashaneli okugeleza abanzi kanye nokubekezelela okuphezulu kwemidiya ehlukahlukene, okuyenza ihambisane noketshezi oluqukethe intlenga, izinhlayiya, i-viscosity ephezulu, noma ukungcola okubalulekile. Ukumelana kwayo nokungcoliswa kanye nokuvala kuphakeme kakhulu kunokwemishini yokushisa amapuleti, okubonisa ukuguquguquka okukhethekile ezimeni zokusebenza ezihlukahlukene.
