Loluphi uhlobo lomtshintshi wobushushu olufanelekileyo?
I-Tubular heat exchanger (isiqhelo semveli, esinokwazi ukuziqhelanisa ngokubanzi)
Inkcazo engundoqo: Ukutshintshwa kobushushu phakathi kwamanzi ashushu kunye nabandayo kufumaneka ngodonga lwetyhubhu. Inesakhiwo esomeleleyo kwaye lolona hlobo lusetyenziswa kakhulu kwindawo yoshishino. Ikwahlulahlulwe ngakumbi kwigobolondo kunye nohlobo lwetyhubhu, uhlobo lwenyoka, uhlobo lwe-coaxial, uhlobo lwetyhubhu ephothiweyo, njl.
1.Iinzuzo eziphambili:
- Inokushisa okunamandla kunye nokumelana noxinzelelo kwaye iyakwazi ukulungelelaniswa kwiqondo lokushisa eliphezulu (Elikhulu okanye elilingana ne-400 degree) kunye noxinzelelo oluphezulu (Olukhulu okanye olulingana ne-10MPa) iimeko zokusebenza, kwaye zifanelekile kwiindidi ezahlukeneyo zeendaba;
2.Iinzuzo eziphambili:
- Ulwakhiwo olomeleleyo noluhlala luhleli, ubomi benkonzo ende, iindleko zokulondolozwa kwexabiso eliphantsi, itekhnoloji esele ikhulile, kwaye ilungele iinkqubo ezinkulu zemizi-mveliso;
1.Izinto ezingeloncedo eziphambili:
- Ukuhanjiswa kobushushu obuphakathi, indawo encinci yokutshintshiselana ngobushushu ngomthamo weyunithi, unyawo olukhulu kunye nobunzima obunzima;
2.Izinto ezingeloncedo eziphambili:
- Iqokobhe -ukucocwa kwecala kunzima, - uyilo lwetyhubhu lunyusa ukumelana nokuqukuqela kwamanzi, kwaye ukucoca ngaphakathi kwityhubhu akulunganga kwezinye iindidi (ezifana no-U{3}}udidi lwetyhubhu).
Umtshintshi wobushushu wePlate (ukusebenza okuphezulu kunye noyilo oludibeneyo, olulungele iimeko zoxinzelelo oluphakathi kunye noluphantsi)
Inkcazo engundoqo: Iipleyiti zetsimbi ezicekethekileyo zicwangciswe ngokunxuseneyo ukuze zenze imijelo ehambayo etshintshanayo, kunye nolwelo olushushu nolubandayo lutshintshiselana ngobushushu ngokuphikisana macala omabini eepleyiti. Iicandelwana zibandakanya uhlobo lwepleyiti ecaba, uhlobo lwepleyiti ejikelezayo, uhlobo lwepleyiti eshushu, njl.
1.Iinzuzo eziphambili:
- Ukugqithisela ubushushu obuphezulu kakhulu, amaxesha angama-3-5 alo hlobo lwe-tubular; isiphithiphithi sinokufezekiswa ngenani eliphantsi leReynolds; Umahluko wobushushu bokutshintshana kobushushu unokuba ngaphantsi njenge-1 degree; isiphumo esibalulekileyo sokugcina amandla.
2.Iinzuzo eziphambili:
- Inesakhiwo esidibeneyo, indawo enkulu yokutshintshiselana kobushushu ngomthamo weyunithi, kwaye ithatha kuphela i-1/5 ukuya kwi-1/10 yendawo yomgangatho weetyhubhu ze-tubular, okwenza ukuba zilungele iimeko ezinendawo encinci.
1.Ezona zinto zingalunganga:
- Amaqondo obushushu kunye noxinzelelo loxinzelelo lulinganiselwe; iiyunithi ezisusekayo ezisemgangathweni zinokumelana namaqondo obushushu obuNgaphantsi okanye obulingana nama-200 kunye noxinzelelo oluNgaphantsi okanye olulingana ne-2.5 MPa, ngelixa kuphela iiyunithi ezidityanisiweyo ezikwaziyo ukumelana{3}} nobushushu obuphezulu kunye{4}}nemeko zoxinzelelo oluphezulu.
2.Ezona zinto zingalunganga:
- Ibeka iimfuneko ezingqongqo kucoceko lwesiphakathi; izikhewu ezimxinwa phakathi kwamacwecwe zenza kube lula ukuvaleka ngokungcola, kwaye iigasket zokutywina ziqheleke ukuguga kwaye zifuna ukutshintshwa ngamaxesha athile.
Umtshintshi woBubushushu boMbhobho woBushushu (Ubuchule obuPhezulu kunye nokuGcinwa kwamandla; Ukulungelelaniswa neeMeko zokuSebenza eziZodwa)
Ingcaciso engundoqo: Ephakathi kwimibhobho yobushushu{0}ephezulu{1}eqhuba ubushushu obuphezulu, obubuchwephesha buhambisa ubushushu ngomjikelo "wokubilisa umphunga, ukuqukuqela komphunga, kunye ne-condensation{2}}reflux." Lenza inoveli, uhlobo olusebenza kakhulu lobushushu obukhethekileyo, lunamacandelwana aquka umsonto{4}osekwe kwimibhobho yobushushu kunye nemibhobho yobushushu bobunzima.
1.Izinto eziluncedo ezingundoqo:
- Inamandla aphezulu okugqithisela ubushushu, ekwaziyo ukuhambisa ubushushu obuninzi phantsi komahluko omncinci wobushushu; Ibonisa iimpawu ezibalaseleyo ze-isothermal kwaye inika amandla abalaseleyo-iziphumo zokugcina.
2.Izinto eziluncedo ezingundoqo:
- Ibonisa isakhiwo esilula, ukusebenza okuthembekileyo, kunye nobomi benkonzo ende, kwaye iyakwazi ukuziqhelanisa neendlela ezahlukeneyo zokutshintsha ubushushu, kuquka irhasi-irhasi{2}}ulwelo, nolwelo{3}}ulwelo.
1.Ezona zinto zingalunganga:
- Uluhlu lobushushu obusebenzayo lulungisiwe; Iindidi ezahlukeneyo zemibhobho yobushushu zifanelekile kwiindidi zeqondo lokushisa elilinganiselwe kwaye aziguquguquki jikelele.
2.Ezona zinto zingalunganga:
- Iindleko zokwenziwa kwemveliso ziphezulu kakhulu, kwaye utyalo-mali lokuqala lwenkunzi luninzi; ngenxa yoko, ayifanelekanga kwizicelo zemizi-mveliso eziqhelekileyo ezibandakanya amazinga aphezulu okuhamba, amaqondo obushushu aphezulu, okanye uxinzelelo oluphezulu.
