I-spiral tube exchanger heat exchanger yenziwa ngokubeka isethi eyodwa noma ngaphezulu yamashubhu elinxeba ngesimo esivunguzayo ngaphakathi kwegobolondo.Izici zayo zihlanganisa isakhiwo esihlangene kanye nendawo yokudlulisa ukushisa enkulu kunamapayipi aqondile.Inendawo enkulu yokudlulisa ukushisa kunepayipi eqondile kanye nokucindezeleka okuphansi kokushisa, kodwa ukuhlanza ngaphakathi kwepayipi kunzima kakhulu. Ingasetshenziselwa ukushisa noma ukupholisa uketshezi olune-viscosity ephezulu.
Izishintshi zokushisa ezivunguzayo (kuhlanganise nezishintshisi zokushisa zamashubhu elivunguzayo kanye nezishintshisi zokushisa zamapuleti ayi-spiral) zibonakala ngesakhiwo sazo esiyingqayizivele seshaneli yokugeleza. Inezinzuzo eziphawulekayo ekusebenzeni kahle kokushintshisana kokushisa kanye nokusetshenziswa kwendawo. Nokho, futhi inemikhawulo efana nobunkimbinkimbi besakhiwo nobunzima bokulungisa. Okulandelayo ukuhlaziya okuningiliziwe kwezinzuzo zayo eziyinhloko kanye nokubi okuyinhloko:
1.Core Izinzuzo
Ukusebenza kahle kokushintshaniswa kokushisa okuphezulu kanye ne-coefficient yokudlulisa ukushisa okukhulu
Uma uketshezi lugeleza ngaphakathi kwesiteshi esivunguzayo, ukuvunguza okunamandla kwakheka ngaphansi kwesenzo samandla aphakathi nendawo. (Ukugeleza kwe-turbulent kungafinyelelwa ngenombolo ephansi ye-Reynolds, ngokuvamile engu-Re > 1000.)Kunciphise ngokuphawulekayo ukumelana nokushisa kwesendlalelo somngcele owuketshezi.Inani lokudlulisa ukushisa elingu-K{{3} liphezulu kakhulu kunalelo le-exchange ye-turbully{{3}nokwemvelo 2-3 izikhathi zegobolondo-kanye nezishintshisi zokushisa zeshubhu).
Uketshezi olushisayo nolubandayo lugeleza ngendlela ephikisayo-yamanje noma enqamulayo-(izishintshi zokushisa ze-spiral plate ngokuvamile ziyi-pure counter-yamanje).Umehluko omkhulu wezinga lokushisa lokushintshanisa nokushisa, Amandla asetshenziswa kahle kakhulu, futhi usayizi wesisetshenziswa mncane ngokwezidingo ezifanayo zokushintsha ukushisa.
I-2.Isakhiwo esihlangene kanye nokusetshenziswa kwendawo ephezulu
Indawo yokushintshisana ngokushisa igxiliswe kusiteshi sokugeleza okuvunguzayo,Indawo yokushintshisana ngokushisa ngeyunithi ngayinye iphindwe izikhathi ezingu-2-4 kunegobolondo-kanye ne-tube heat exchanger.Ayijwayele ukukala futhi kulula ukuyihlanza nokuyinakekela (ngezishintshisi zokushisa ze-spiral plate).
Ekugelezeni okunezinxushunxushu, uketshezi lunomphumela oqinile wokugaya odongeni lwamapayipi, olungavimbela ngokuphumelelayo ukufakwa kokungcola; ngisho noma inani elincane lesilinganiso likhiqizwa, lingasuswa ngokubuyisela emuva noma ukuhlanza amakhemikhali.
Izishintshi zokushisa ze-Spiral plate azinazo izindawo ezifile eziteshini zazo zokugeleza, eziqinisekisa ukugeleza koketshezi olufanayo futhi zigwema inkinga yokungcola ebangelwa igebe phakathi kwama-baffles nenqwaba yeshubhu kugobolondo-kanye{1}}nezishintshi zokushisa zeshubhu.
Ingakwazi ukuphatha izinhlobo ezihlukahlukene zoketshezi, okuhlanganisa uketshezi lwe-viscous (i-turbulence inganciphisa ukumelana ne-viscous) kanye noketshezi oluqukethe inani elincane lezinhlayiya (umzila wokugeleza okuvunguzayo awuvimbeki kalula, futhi izinhlayiya zingakhishwa ngoketshezi).
3. Ukusetshenziswa kwamandla okuphansi kanye nezindleko eziphansi zokusebenza:
Ukugeleza kwesiphithiphithi kunokulahlekelwa kokumelana okuphansi uma kuqhathaniswa (uma kuqhathaniswa nesiphithiphithi esiphoqelelwe kugobolondo-kanye{1}}nezishintshisi zokushisa zamashubhu), kudinga amandla amancane epompo, futhi kusebenzisa amandla amancane phakathi-nokusebenza kwesikhathi eside.
Inesakhiwo esiyinkimbinkimbi, kunzima ukuyikhiqiza, ibandakanya izinqubo zokushisela eziyinkimbinkimbi, futhi akulula ukuyigcina isesimweni esihle. Ingcindezi elinganiselwe{1}}umthamo wokuthwala (uma kuqhathaniswa negobolondo-kanye{3}}nezishintshi zokushisa zamashubhu) futhi ivinjelwa amandla esakhiwo: Izishintshi zokushisa ze-Spiral plate ngokuvamile zinengcindezi ephansi{{4}{}}ethwala ama-exchange angu-5} abe namagobolondo{{5}okuthwala amagobolondo} kanye nokushisa (igobolondo-kanye-neshubhuizishintshi zokushisa cifinyelela izingcindezi eziphezulu ngokujiya igobolondo nokusebenzisa-ishubhu yamandla aphezulu).Uhlelo lokusebenza lukhawulelwe ngaphansi-izimo zokucindezela okuphezulu (ezifana nokucindezela > 10MPa).
Okungenhla ukuqonda kwami izinzuzo kanye nokubi kwezishintshi zokushisa kwamashubhu okuvunguza.Uma ungathanda ukufunda okwengeziwe ngamayunithi esishintshisi sokushisa noma unentshisekelo yokuwathenga,Sicela uthumele i-imeyili ku-9988xiaoshuai@gmail.com, futhi sizokuphendula ngokushesha uma sibona i-imeyili yakho!
