Tube in Tube Heat Exchangers: Tataiso e FeletsengSengoliloeng sena se fana ka kakaretso e felletseng ea tube ka har'a li-heaters tsa mocheso, ho hlahloba moralo oa bona, lits'ebetso, melemo, mathata, le mekhoa ea khetho. Re batlisisa ka mefuta e fapaneng, lisebelisoa, le lipalo, re fana ka leseli le sebetsang bakeng sa lienjineri le litsebi tse sebetsang ka sistimi ea phetisetso ea mocheso.
Tube ka har'a li-heaters tsa mocheso, e tsejoang hape ka hore ke liphaephe tse peli tse futhumatsang mocheso, ke tse ling tsa mefuta e bonolo le ea bohlokoa ka ho fetisisa ea ho futhumatsa mocheso. Li sebelisoa haholo liindastering tse fapaneng bakeng sa phetisetso e nepahetseng ea mocheso lipakeng tsa maro a mabeli. Tataiso ena e tla u thusa ho utloisisa ts'ebetso ea bona, lintlha tsa moralo le ts'ebeliso e sebetsang. Re tla boela re buisane ka ts'ebetso ea khetho, re nahane ka lintlha tse kang ho phalla, ho fapana ha mocheso, le ho theoha ha khatello. Ho utloisisa lintlha tsena ho bohlokoa bakeng sa ts'ebetso e nepahetseng le ts'epo ea nako e telele.
Ho utloisisa Lintho tsa Motheo tsa Tube ho Tube Heat Exchangers
Moralo le Kaho
A tube ka mochine oa mocheso oa tube e na le li-tubes tse peli tsa concentric, e 'ngoe ka hare ho e' ngoe. Mokelikeli o phalla ka har'a tube e ka hare, ha mokelikeli oa bobeli o phalla sebakeng sa annular pakeng tsa li-tubes tse ka hare le tse ka ntle. Ho fetisoa ha mocheso ho etsahala ka lerako la tube, ho tsamaisoa ke conduction le convection. Mekelikeli e ka phalla ka litlhophiso tsa co-current (ka lehlakoreng le le leng) kapa li-counter-current (ka lehlakoreng le fapaneng), 'me phallo e khahlanong le hona joale e fana ka ts'ebetso e phahameng haholo.
Mefuta ea li-tube ho li-Tube Heat Exchangers
Liphetoho li teng ho itšetlehile ka tšebeliso e khethehileng le litlhoko. Tsena li kenyelletsa:
- Licheso tsa mocheso o le mong: Mekelikeli e phalla hang ka har'a li-tubes tse fapaneng.
- Lichelete tse fapaneng tsa mocheso: Mekelikeli e feta makhetlo a mangata ka har'a li-tubes, e leng se eketsang katleho ea ho fetisa mocheso. Sena se ka kenyelletsa U-turn kapa litlhophiso tse ling.
- Ka kapa ntle le mathata: Li-baffles li ka eketsa moferefere le ho eketsa phetiso ea mocheso, empa li ka eketsa ho theoha ha khatello.
Lisebelisoa
Khetho ea thepa e itšetlehile ka maro a amehang, mocheso o sebetsang le likhatello, le litlhoko tsa ho hanyetsa ho bola. Lisebelisoa tse tloaelehileng li kenyelletsa tšepe e sa hloekang, koporo le li-alloys tse fapaneng. Khetho e hloka ho nahanoa ka hloko ho netefatsa ho lumellana le ho phela nako e telele.
Melemo le Mefokolo ea Tube ho Tube Heat Exchangers
Melemo
Li-exchange tsena li tsebahala ka:
- Bonolo ba moralo le kaho.
- Theko e batlang e le tlase.
- Ho hloekisa habonolo le tlhokomelo.
- E loketse lits'ebetso tsa khatello e phahameng.
Mefokolo
Meeli e meng e lokelang ho nahanoa e kenyelletsa:
- Sebaka se batlang se le tlase sa ho fetisa mocheso ka bophahamo ba yuniti ha se bapisoa le meralo e rarahaneng.
- Tšebeliso e fokolang bakeng sa litefiso tse phahameng haholo tsa ho fetisa mocheso.
- Monyetla oa ho senya le ho eketsa.
Lisebelisoa tsa Tube ho Tube Heat Exchangers
Tube ka har'a li-heaters tsa mocheso li sebelisoa liindastering tse ngata, ho kenyelletsa:
- Ts'ebetso ea lik'hemik'hale
- Ho lokisa lijo le lino
- Ho etsa meriana
- Ho hlahisa matla
- Sistimi ea HVAC
Lisebelisoa tse khethehileng hangata li kenyelletsa metsi a futhumatsang kapa a tsidifatsang kapa likhase, joalo ka ho futhumatsa lijo ka har'a setsi sa lik'hemik'hale, pasteurization ea lebese ha ho etsoa lijo, kapa ho futhumatsa oli e tlotsang mochining. Ho ba bonolo le ho tiea ha bona ho ba etsa khetho e ratoang maemong a mangata.
Litlhaloso tsa Khetho le Moqapi
Lintlha Tseo U Lokelang ho li Nahana
Ho khetha e loketseng tube ka mochine oa mocheso oa tube e hloka tlhahlobo e hlokolosi ea liparamente tse 'maloa:
- Litekanyetso tsa phallo ea metsi
- Phapang ea mocheso
- Khatello e theoha
- Lintho tsa mokelikeli (viscosity, conductivity ea mocheso, joalo-joalo)
- Ho lumellana ha lintho
- Sekhahla se hlokahalang sa ho fetisa mocheso
Palo le Sizing
Sekhahla se nepahetseng le moralo li hloka tšebeliso ea lipalo tsa phetiso ea mocheso, hangata tse kenyelletsang mokhoa oa log mean the temperature difference (LMTD). Li-software tse khethehileng kapa libuka tsa boenjiniere li ka thusa ho khetholla boholo bo nepahetseng le tlhophiso bakeng sa ts'ebeliso e fanoeng. Ho bohlokoa ho kenyelletsa baenjiniere ba nang le boiphihlelo ts'ebetsong ena ho netefatsa ts'ebetso e nepahetseng le e bolokehileng.
Tlhokomelo le Tlhoekiso
