Ii-air dryer esiqandisiniumshini wokomisa umoya ocindezelweyo osebenzisa izimiso zomzimba ukuze umise umswakama emoyeni ocindezelweyo ongaphansi kwendawo yamazolo, uwujiye ube amanzi awuketshezi asuka emoyeni ocindezelwe bese ewukhipha.Ikhawulelwe indawo ebanda amanzi, ngokwembono izinga lokushisa layo lendawo yamazolo lingasondela ku-0 degrees.Ngokuvamile, izinga lokushisa lezinga lamazolo le-dryer enhle lingafinyelela ku-10 degrees.
Ngokomehluko phakathi kwezishintshi zokushisa zeokomisa umoya esiqandisini, okwamanje kunezinhlobo ezimbili zokomisa umoya ezinezishintshi zokushisa ze-tube-fin kanye nezishintshisi zokushisa zohlobo lwepuleti (okubhekiselwa kuzo njengokushintshisana kwamapuleti) emakethe.Ngenxa yobuchwepheshe baso obuvuthiwe, ukwakheka okuhlangene, ukusebenza kahle kokushisa okuphezulu, futhi akukho ukungcoliswa kwesibili, isomisi somoya esishisayo sesiphenduke insakavukela emakethe yokomisa umoya.Kodwa-ke, kuningi okungalungile ekwakhiweni nasekusetshenzisweni kwesishintshi sokushisa esidala se-tube-fin.Ukusebenza okuyinhloko kulezi zici ezilandelayo:
1. Ivolumu enkulu:
Isishintshi sokushisa se-tube-fin ngokuvamile sinesakhiwo esiyisilinda esivundlile.Ukuze uvumelane nokuma kwesishintshi sokushisa, yonke idizayini yomshini wesiqandisi nokomisa ingalandela kuphela indlela yokushintsha ukushisa.Ngakho-ke, wonke umshini mkhulu, kodwa isikhala sangaphakathi asinalutho., Ikakhulukazi imishini ephakathi nendawo nenkulu, 2/3 yesikhala esingaphakathi kwawo wonke umshini siyinsada, ngaleyo ndlela ibangele ukumosheka kwesikhala okungadingekile.
2. Isakhiwo esisodwa:
I-tube-fin heat exchanger ngokuvamile yamukela idizayini eyodwa-to-one, okungukuthi, umshini wokushisa ohambisanayo wokucubungula amandla uhambisana nomshini wokushisa ohambisanayo wokucubungula amandla, okuholela ekukhawulweni kwenqubo yokukhiqiza futhi ayikwazi ukuguquguquka isetshenziswe ngokuhlanganiswa.Izindlela zokusebenzisa isishintshi sokushisa esifanayo ukwenza okomisa umoya okunamandla ahlukene okucubungula, okuzoholela nakanjani ekwandeni kwe-inventory yezinto ezingavuthiwe.
3. Ukusebenza kahle kokushintshaniswa kokushisa
Ukusebenza kahle kokudluliswa kokushisa kwe-tube-fin heat exchanger ngokuvamile cishe ku-85%, ngakho-ke kuyadingeka ukufeza umphumela ofanele wokudlulisa ukushisa.Umklamo walo lonke uhlelo lwesiqandisi kufanele ukhuphuke ngaphezu kuka-15% ngesisekelo sokubala okudingekayo. umthamo wesiqandisi, ngaleyo ndlela andise izindleko zesistimu kanye nokusetshenziswa kwamandla.
4. Amabhamuza omoya kusishintshi sokushisa se-tube-fin
Isakhiwo se-fin yesikwele kanye negobolondo eliyindilinga le-tube-fin heat exchanger lishiya isikhala sokushintshisana esingashisi esiteshini ngasinye, okubangela ukubhamuza komoya.Ama-baffles we-evaporator avumela omunye womoya ocindezelwe ukuba uphume ngaphandle kokushintshana kokushisa.Lokhu kunciphisa iphuzu lamazolo egesi yomkhiqizo, futhi ukwandisa umthamo wokupholisa akuyixazululi ngokuphelele inkinga.Ngakho-ke, indawo yokucindezela yamazolo emshini wokomisa i-tube-fin ngokuvamile ingaphezulu kuka-10°C, engakwazi ukufinyelela ku-2°C ofanele.
5. Ukumelana nokugqwala okungalungile
Izishintshisi zokushisa ze-tube-fin ngokuvamile zenziwa ngamashubhu ethusi namaphiko e-aluminium, kanti indawo okuqondiswe kuyo igesi evamile ecindezelwe kanye negesi engagqwali.Uma isetshenziswa ezikhathini ezithile ezikhethekile, njengezikomisa iziqandisi zasolwandle, Imishini ekhethekile yokupholisa igesi nokomisa, njll., ijwayele ukugqwala, okufinyeza kakhulu impilo yesevisi, noma ingakwazi nhlobo ukusetshenziswa.
Uma kubhekwa izici zesishintshi sokushisa se-tube-fin esibalulwe ngenhla, isishintshi sokushisa sepuleti singakwazi ukwenza lokhu kushiyeka.Incazelo eqondile imi kanje:
1. Isakhiwo esihlangene nosayizi omncane
Isishintshi sokushisa sepuleti sinesakhiwo sesikwele futhi sithatha indawo encane.Ingahlanganiswa ngokuguquguqukayo nezingxenye zesiqandisi emishinini ngaphandle kokuchitha isikhala esiningi.
2. Imodeli iyaguquguquka futhi iyashintsha
Isishintshi sokushisa sepuleti singahlanganiswa ngendlela eyimodular, okungukuthi, singahlanganiswa sibe namandla okucubungula adingekayo ngendlela engu-1+1=2, okwenza umklamo wawo wonke umshini uguquguquke futhi ushintshe, futhi ungalawula ngempumelelo i-inventory yempahla eluhlaza.
3. Ukusebenza kahle kokushintshaniswa kokushisa okuphezulu
Isiteshi sokugeleza sokushintshanisa ukushisa kwepuleti sincane, ama-plate fins angama-waveform, futhi izinguquko ze-cross-section ziyinkimbinkimbi.Ipuleti elincane lingathola indawo enkulu yokushintshanisa ukushisa, futhi isiqondiso sokugeleza kanye nezinga lokugeleza koketshezi kushintshwa njalo, okwandisa izinga lokugeleza koketshezi.Ukuphazamiseka, ngakho-ke kungafinyelela ukugeleza kweziyaluyalu ngesilinganiso esincane kakhulu sokugeleza.Kusishintshi sokushisa segobolondo neshubhu, uketshezi olubili lugeleza ohlangothini lweshubhu kanye nohlangothi lwegobolondo ngokulandelana.Ngokuvamile, ukugeleza kuwukugeleza kwe-cross-flow, futhi i-logarithmic isilinganiso somehluko wokulungisa izinga lokushisa sincane., Futhi izishintshi zokushisa zamapuleti ngokuvamile ziwukugeleza okuhambisanayo noma okuphikisayo, futhi i-coefficient yokulungisa ivamise ukuba ngu-0.95.Ukwengeza, ukugeleza koketshezi olubandayo nokushisa okushisayo kumshini wokushisa wepuleti kuhambisana nendawo yokushintshanisa ukushisa ngaphandle kokugeleza kwe-bypass, okwenza i-plate exchanger ukushisa Umehluko wokushisa ekupheleni komshini wokushisa uncane, ongaba ngaphansi kuka-1 °C.Ngakho-ke, indawo yamazolo ecindezela okomisa isiqandisi kusetshenziswa isishintshi sokushisa sepuleti ingaba ngaphansi kuka-2°C.
4. Ayikho i-engeli efile yokushintshanisa ukushisa, ngokuyisisekelo ifinyelela ukushintshaniswa kokushisa okungu-100%.
Ngenxa yendlela yaso ehlukile, isishintshi sokushisa sepuleti senza isishintshi sokushisa sithinte ngokugcwele indawo yepuleti ngaphandle kwama-engeli afile okushintshanisa ukushisa, kungabikho izimbobo zokudonsa amanzi, futhi kungabikho ukuvuza komoya.Ngakho-ke, umoya ocindezelweyo ungafinyelela ukushintshaniswa kokushisa okungu-100%.Qinisekisa ukuzinza kwendawo yamazolo yomkhiqizo oqediwe.
5. Ukumelana nokugqwala okuhle
Isishintshi sokushisa kwepuleti senziwa nge-aluminium alloy noma isakhiwo sensimbi engagqwali, esinokumelana nokugqwala okuhle futhi singagwema nokungcoliswa kwesibili komoya ocindezelwe.Ngakho-ke, ingashintshwa ngezikhathi ezikhethekile ezihlukahlukene, kuhlanganise nemikhumbi yasolwandle, enegesi eyonakalisayo Imboni yamakhemikhali, kanye nezimboni zokudla nezithakazelo eziqinile.
Ukuhlanganisa izici ezingenhla, isishintshi sokushisa sepuleti sinezinzuzo ezingenakunqotshwa zeshubhu kanye ne-fin heat exchanger.Uma kuqhathaniswa neshubhu kanye ne-fin heat exchanger, isishintshi sokushisa sepuleti singonga u-30% ngaphansi komthamo ofanayo wokucubungula.Ngakho-ke, ukumiswa kwesistimu yesiqandisi yomshini wonke kungancishiswa ngo-30%, futhi ukusetshenziswa kwamandla kungabuye kuncishiswe ngaphezu kuka-30%.Umthamo womshini wonke nawo ungancishiswa ngaphezu kuka-30%.
Isibonisi sakamuva sokuguqula ipuleti esishintshashintshayo esiqandisini
