Uhlalutyo lwemarike yokutshintsha ubushushu

Imarike yokutshintshiselana kobushushu yehlabathi ixabisa i-US $17.58 ibhiliyoni kwi-2022 kwaye kuqikelelwa ukuba ikhule kwi-CAGR ye-5.1% phakathi kwe-2023 kunye ne-2030. Imfuno ekhulayo yokuphucula ulawulo lwe-thermal kumacandelo ahlukeneyo, afana nokutya, i-oyile kunye negesi, i-petrochemicals, imveliso yamandla, kunye nefriji, kulindeleke ukuba ikhulise ukukhula ngexesha lokuqikelelwa.

Ngaphaya koko, ukuqhubela phambili kwetekhnoloji ukomeleza ubushushu Ukuqina kwabarhwebi, ixabiso, ukusebenza kakuhle kwamandla, kunye nokubumbana kuya kuthengisa amafutha kule minyaka izayo. I-US yavela njengeyona ntengiso iphezulu ngo-2022, ngenxa yokwenziwa kwemizi-mveliso kunye notyalo-mali olukhawulezayo kumbane ohlaziyekayo. Ezinye iimarike zamandla ezibalulekileyo ziquka iJapan, iChina, iIndiya, kunye neRashiya.

Yintoni izitshintshi zobushushu?

Izitshintshi zobushushu zizixhobo ezihambisa amandla obushushu ukusuka kulwelo olunye ukuya kolunye ukulawula ubushushu bento. Abatshintshi bobushushu ngokwesiqhelo bahlula imijelo yolwelo emibini, enye iyabanda kwaye enye ishushu, kusetyenziswa ipleyiti ehambisa i-thermal, ihambisa amandla obushushu ukusuka kumsinga ukuya komnye. Izitshintshi zobushushu eziqhelekileyo ziquka iibhoyila, iifurnashi, iifriji, ii-air conditioners, kunye neeradiator zemoto.

ubushushu abatshintshisi zihlelwa ngokwesiqhelo zibe ziindidi ezintathu ngokusekwe kuyilo lwazo: icwecwe, iqokobhe kunye netyhubhu, kunye nee-ACHEs. Ezi ntlobo zintathu zahluke kakhulu kuyilo, ukuntsokotha, kunye nezicelo.

Ipleyiti okanye ipleyiti yokutshintsha ubushushu

Amacwecwe esinyithi asetyenziswa kwezi ubushushu abatshintshiselwano basebenza njengesithintelo se-thermal conductive phakathi kolwelo. Ulwelo olubandayo nolushushu lujikeleza phakathi kweepleyiti, ngelixa i-vanes engatshintshiyo eyaziwa ngokuba zii-baffles zikhokela isikhokelo sokukhetha umtshintshi wobushushu phakathi kwazo. Ngenxa yommandla wabo omkhulu, iipleyiti zisebenza ngakumbi kunee-tube exchangers. Nangona kunjalo, ukutywina ii-gaskets ezinkulu phakathi kwala macwecwe kunzima, ukunciphisa ezi zixhobo kwimveliso encinci kunye nezicelo ze-viscous eziphantsi kunye noxinzelelo oluncinci ukuya kwimodareyitha yokusebenza kunye neemfuno zobushushu, ngokuqhelekileyo phantsi kwe-150 °C.

eziluncedo

Izixhobo zokutshintsha ubushushu kwipleyiti kucingelwa ukuba zisebenza ngokuphindwe kahlanu kuneqokobhe netyhubhu eziyilwe ngenxa yokuba zinokubuyisa ubushushu obuninzi. Bakwathatha indawo encinci yomgangatho, ubomi benkonzo obude, kwaye bafuna ukulungiswa okuncinci. Iipleyiti nazo zinokujongwa ngokulula okanye zicocwe. Ngaphaya koko, abatshintshisi bobushushu bepleyiti baneendleko zokusebenza eziphantsi ngenxa yokukwazi ukufezekisa ukuhanjiswa kobushushu obuphezulu ngendawo encinci yomhlaba. Iindleko eziphambili zivela ekutshintshweni kweegaskets kwaye, ngamanye amaxesha, iipleyiti.

I-Plate exchangers lukhetho oluhle kakhulu kuba basebenzisa indlela yokushisa esondeleyo, apho i-fluid ebandayo ifudumala kwiqondo lokushisa elikufutshane nokungena kwamanzi ashushu, okuvumela ukuvuselelwa ngakumbi kunye nokubuyisela ubushushu. Kwakhona benza ukhetho olufanelekileyo kwiindawo ezinendawo encinci.

I-modularity yale mveliso yinzuzo eyongezelelweyo: kulula ukudibanisa kunye nokutshatyalaliswa kwisayithi kuba balinganisa i-6% kuphela njengegobolondo kunye neeyunithi zetyhubhu.

Iqokobhe kunye nezitshintshi zobushushu ityhubhu

Kwigobolondo kunye ne-tube yokutshintshiselana kobushushu, uluhlu lweetyhubhu ezixande okanye ezijikelezayo zifakwe kwi-casing enkulu, ene-cylindrical-shaped casing. Ulwelo oluza kufudunyezwa okanye lugodolwe luhamba kule mibhobho, ngelixa ulwelo lwesibini (lokudluliselwa kobushushu) luqukuqela phezu kwazo ngaphakathi kweqokobhe. Oku kugeleza kuqondiswa yi-baffles, ekwaxhasa i-tube bundles.

Olu hlobo umzimba idume kakhulu, ibalelwa kwi-60% yazo zonke izitshintshi zobushushu. Zingasetyenziselwa kwiindawo zombini eziphantsi kunye noxinzelelo oluphezulu kunye nobushushu, kodwa ukwakhiwa kwazo okuqinileyo kwenza ukuba zifaneleke kakhulu kwizicelo zoxinzelelo oluphezulu. Kananjalo banomlinganiselo ophezulu wobunzima bomthamo wokuhambisa ubushushu. Iindidi zeShell kunye netyhubhu ziqhele ukusetyenziswa kwiijenereyitha zomphunga, izityalo zamandla, kunye ne-oyile kunye ne-hydraulic fluid ukupholisa izicelo kwiinjini.

eziluncedo

Ngenxa yokucocwa okukhulu phakathi kweqokobhe kunye neetyhubhu, olu luyilo lufaneleke kakuhle ulwelo oluqulethe iinxalenye. Banokuphatha uxinzelelo oluphezulu ubushushu Udluliselo olungcono kunezinye iimodeli kuba zineqokobhe elikhulu lesitya soxinzelelo kunye neenyanda zetyhubhu ngaphakathi.

Ukongeza, ulwelo alufane lungcolise isixhobo kwiqokobhe kunye noyilo lwetyhubhu. I-fouling ibhekisela ekuqokeleleni kweediphozithi ezivela kulwelo oludlulayo ngexesha lokudluliselwa kobushushu. Ngaphezu koko, xa kusetyenzwa i-high-fouling liquids, i-baffles inokongezwa kwi-tube yokwandisa i-turbulence kunye nokunciphisa amathuba okuba amaqhekeza abambelele ngaphakathi kweetyhubhu.

Izitshintshi zobushushu ezipholiswe ngumoya (ACHEs)

Izitshintshi zobushushu ezipholileyo zomoya, ekwaziwa ngokuba ziifeni ze-fin, sebenzisa umoya ukwala ubushushu obuphuma kulwelo ngokuthe ngqo. Iifeni zityhala umoya phezu komphezulu wemibhobho okanye iipleyiti, eziqulathe ulwelo lokucubungula. Ziyeyona ndlela ilungileyo kwiqokobhe eliqhelekileyo elipholiswe ngamanzi kunye nezitshintshi zobushushu betyhubhu, ngakumbi xa amanzi enqabile.

Olu hlobo lobushushu lusetyenziswa kwiintlobo ezahlukeneyo zezicelo. Kulula ukuzisebenzisa kunye nokuzigcina kuba umoya awubangeli ukubola okanye ukungcolisa ulwelo. Ngaphaya koko, imiba yokusingqongileyo ikwajongwa njengento engeyiyo inkxalabo ngabatshintshi bobushushu obupholileyo bomoya.

eziluncedo

Ii-ACHEs zicingelwa ukuba zisebenza ngakumbi kuneqokobhe kunye netyhubhu uyilo. Ngenxa yokuba zinenkqubo evaliweyo, zibeka umngcipheko omncinci wokungcoliseka kwamanzi. Ukongeza, abafuni ukusetyenziswa kwamanzi, ukuthintela ukunqongophala kwamanzi kunye nokuphelisa imfuno indawo yokucoca amanzi. Ngaphezu koko, zifuna ukulungiswa okuncinci kwaye azifuni ukucocwa rhoqo.

Yintoni ekufuneka uyiqwalasele xa ukhetha umtshintshi wobushushu

Inyathelo lokuqala kukuhlalutya ngokucokisekileyo uyilo lomtshintshisi wobushushu kunye nezicelo kwiimbono ezahlukeneyo. Oku kubandakanya ukuhlola inkqubo yayo yombane, iipropati zolawulo lobushushu, uyilo, kunye neminye imiba. Ngaphaya koko, isixokelelwano kufuneka sibe sisayizi esifanelekileyo ukuze singene kwindawo ekhoyo kwaye ibonelele ngeyona ndlela ifanelekileyo yokupholisa. Iziphumo zolu hlalutyo ziya kunceda ekunqumeni uhlobo olungcono kakhulu lokutshintsha ubushushu kwisicelo esikhoyo.

Ukupholisa kwendawo

Xa ukhetha abatshintshi bobushushu, kuyahlawuleka ukufunda malunga neenzuzo zokupholisa kwendawo:. inkqubo yokugcina ubushushu bangaphakathi ebiyelweyo yombane ngaphezu nje iqondo lobushushu ambient yangaphandle. Kwiimeko ezininzi, ukupholisa kwendawo kuyahlangabezana neemfuno zokupholisa zesixokelelwano.

Ukupholisa kunokufezekiswa kusetyenziswa iindlela zokusingqongileyo, ezinjengokusebenzisa ulwelo lokupholisa ukufunxa nokuhambisa inkunkuma yombane ubushushu. Ngaphaya koko, ukutshintshela kwiindlela zemveli, ezinje ngeeyunithi zoxinzelelo lomoya, ukuya kwisipholisi sendalo esingqongileyo kunokubangela ukonga amandla ngakumbi kunye nemisebenzi yogcino oluphantsi.

Ulawulo lobushushu

Njengoko kuchaziwe ngasentla, inkqubo yokupholisa elungelelanisiweyo ineengenelo ezininzi, kubandakanywa iindleko ezisezantsi zokusebenza. Amashishini kufuneka, nangona kunjalo, athathele ingqalelo eminye imimandla apho ulawulo lwe-thermal lunokulungiswa kunye nokuba lufanelekile na ubushushu umtshintshisi angayenza loo nto.

Ngokomzekelo, abaninzi basebenzisa iinkqubo zokucocwa kwamanzi amdaka angaphakathi ezifuna ukusetyenziswa ngokuqhubekayo kobushushu. Ukuba kuyenzeka, izitshintshi zobushushu zingayilwa ukuba ziphinde zisebenzise ubushushu bombane obusetyenzisiweyo kwezinye iinkqubo, ezinjengokucoca amanzi amdaka.

izicelo

I-Shell kunye ne-tube exchangers zisetyenziswa kwiinkqubo ezahlukeneyo zemizi-mveliso, kubandakanywa ukwenziwa komphunga, ukucocwa kwe-oyile nokupholisa, kunye nokupholisa kwimizi-mveliso. Ngakolunye uhlangothi, izitshintshi zobushushu ezicwengiweyo zisetyenziswa ngokuqhelekileyo kwiziko kunye nezityalo zokulungisa imichiza.

I-air-cooled heat exchangers isetyenziswa ngokubanzi kwi-oyile kunye ne-gas industry, izityalo ze-petrochemical, kunye neendawo zokucoca kwiimeko zoxinzelelo oluphezulu kunye nobushushu obuphezulu, kunye neendawo ezinobungozi ezinobuncwane.

isiphelo
