Iityhubhu kunye nezitshintshi zobushushu ityhubhu

Ingcaciso yeMveliso

I-tube kunye ne-tube yokutshintshiselana kobushushu zisetyenziswa ngokubanzi kwimveliso yeekhemikhali kunye notywala. Ubukhulu becala iqulunqwe iqokobhe, ishidi ityhubhu, ityhubhu yokutshintshiselana ngobushushu, intloko, i-baffle njalo njalo. Izinto ezifunekayo zingenziwa nge-carbon steel plain, ubhedu okanye insimbi engenasici. Ngexesha lokutshintshana kobushushu, i-fluid ingena kumbhobho wokudibanisa wentloko, igeleza kumbhobho, kwaye iphuma kumbhobho wokuphuma kwelinye icala lentloko, ebizwa ngokuba yicala lombhobho; olunye ulwelo lungena lusuka kudibaniso lweqokobhe, luze luqukuqele ukusuka kwelinye icala leqokobhe. Omnye umlomo uyaphuma, obizwa ngokuba liqokobhe elikwicala leqokobhe kunye netyhubhu yokutshintsha ubushushu.

Ubume beqokobhe kunye ne-tube exchanger heat exchanger ilula, icwecwe kwaye ingabizi, kodwa ukucoca ngoomatshini akunakwenziwa ngaphandle kombhobho. I-tube bundle ye-heat exchanger idibaniswe neshidi ityhubhu, amaphepha etyhubhu adityaniswe ngokulandelanayo ukuya kwiziphelo ezimbini zegobolondo, ikhava ephezulu idityaniswe nekhava ephezulu, kunye nekhava ephezulu kunye negobolondo inikwe ulwelo. indawo yokungena kunye nombhobho wokukhupha amanzi. Uluhlu lwe-baffles perpendicular to the tube bundle luvame ukufakwa ngaphandle kweetyhubhu zegobolondo kunye ne-tube heat exchanger. Ngelo xesha, uxhulumaniso phakathi kombhobho kunye nephepha le-tube kunye negobolondo liqinile, kwaye kukho ama-fluids amabini anamaqondo okushisa ahlukeneyo ngaphakathi nangaphandle kombhobho. Ke ngoko, xa umahluko weqondo lobushushu phakathi kodonga lwetyhubhu kunye nodonga lweqokobhe lukhulu, ngenxa yokwandiswa kwe-thermal eyahlukileyo kwezi zimbini, kuya kuveliswa uxinzelelo olukhulu lobushushu, ukuze iityhubhu zijijelwe okanye zikhululeke kwi-tube plate. iqokobhe kunye netyhubhu yokutshintsha ubushushu, kunye nomonakalo wokutshintsha ubushushu.

Ukoyisa uxinzelelo lobushushu bomahluko, iqokobhe kunye netyhubhu yomtshintshisi wobushushu kufuneka ibe nesixhobo sembuyekezo yomahluko wobushushu. Ngokuqhelekileyo, xa umehluko weqondo lokushisa phakathi kodonga lwetyhubhu kunye nodonga lwegobolondo lungaphezu kwama-50 ° C, ngenxa yezizathu zokhuseleko, ityhubhu kunye ne-tube exchanger heat exchanger kufuneka ibe nesixhobo sokuhlawulela umahluko wobushushu. Nangona kunjalo, isixhobo sembuyekezo (ijoyinti yokwandiswa) ingasetyenziswa kuphela xa umahluko weqondo lobushushu phakathi kodonga lweqokobhe kunye nodonga lombhobho lungaphantsi kwama-60 ~ 70 ° C kunye noxinzelelo lwecala leqokobhe lolwelo aluphezulu. Ngokubanzi, xa uxinzelelo lwecala leqokobhe lungaphezulu kwe-0.6Mpa, kuba nzima ukwandisa kunye nenkontileka ngenxa yeringi yembuyekezo eshinyeneyo. Ukuba umphumo wembuyekezo yokuhluka kweqondo lokushisa ulahlekile, ezinye izakhiwo kufuneka ziqwalaselwe.

Ifilimu eshushu yangoku yeqokobhe kunye netyhubhu yokutshintshiselana kobushushu ikakhulu ithatha itekhnoloji ye-eddy yangoku eshushu yokuhambisa ubushushu, eyandisa isiphumo sokuhambisa ubushushu ngokuguqula imeko yentshukumo yolwelo. Ukuya kuthi ga kwi-10000W/m2℃. Kwangaxeshanye, ulwakhiwo luqonda imisebenzi yokumelana ne-corrosion, ukumelana nobushushu obuphezulu, ukumelana noxinzelelo oluphezulu, kunye ne-anti-scaling. Imijelo ye-fluid yezinye iintlobo zokutshintsha ubushushu zikwimo yendlela ehamba ngayo, eyenza ukujikeleza kwimibhobho yokutshintsha ubushushu, okunciphisa i-coefficient yokudlulisa ukushisa.
