Tube in Tube Heat Exchangers: A Comprehensive Guide Nkhaniyi ikupereka mwatsatanetsatane za chubu mu chubu kutentha exchanger, kuyang'ana mapangidwe awo, ntchito, ubwino, kuipa, ndi zosankha. Timasanthula mitundu yosiyanasiyana, zida, ndi kuwerengera, kupereka zidziwitso zothandiza kwa mainjiniya ndi akatswiri omwe amagwira ntchito ndi makina otengera kutentha.
Tube mu chubu chosinthira kutentha, omwe amadziwikanso kuti osinthanitsa kutentha kwa mapaipi awiri, ndi ena mwa mitundu yosavuta komanso yofunikira kwambiri yosinthira kutentha. Amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana kuti azitha kutentha kutentha pakati pa madzi awiri. Bukuli likuthandizani kumvetsetsa momwe amagwirira ntchito, malingaliro apangidwe, komanso momwe angagwiritsire ntchito. Tidzakambirananso za kusankha, poganizira zinthu monga kuthamanga kwa magazi, kusiyana kwa kutentha, ndi kuchepa kwa mphamvu. Kumvetsetsa zinthu izi ndikofunikira kuti mugwire bwino ntchito komanso kudalirika kwanthawi yayitali.
Kumvetsetsa Zoyambira za Tube mu Tube Heat Exchangers
Kupanga ndi Kumanga
A chubu mu chubu kutentha exchanger imakhala ndi machubu awiri okhazikika, limodzi mkati mwa linalo. Madzi amadzimadzi amayenda mu chubu chamkati, pamene madzimadzi achiwiri amayenda mumpata wa annular pakati pa machubu amkati ndi akunja. Kusintha kwa kutentha kumachitika kudzera pa khoma la chubu, motsogozedwa ndi conduction ndi convection. Madzi amadzimadzi amatha kuyenda mozungulira (komweko) kapena kutengera komweko (koyang'ana kosiyana), komwe kumayenderana komwe kumapereka mphamvu zambiri.
Mitundu ya Tube mu Tube Heat Exchangers
Kusiyanasiyana kulipo kutengera kagwiritsidwe ntchito ndi zofunikira. Izi zikuphatikizapo:
- Zosinthira kutentha kamodzi kokha: Madzi amadzimadzi amayenda kamodzi kudzera m'machubu.
- Multi-pass heat exchanger: Madziwo amadutsa kangapo m'machubu, ndikuwonjezera kutentha kwa kutentha. Izi zitha kuphatikiza ma U-turn kapena masinthidwe ena.
- Ndi kapena popanda zovuta: Ma baffles amatha kukulitsa chipwirikiti ndikuwonjezera kutentha, koma amathanso kuwonjezera kutsika kwamphamvu.
Zipangizo
Kusankhidwa kwa zinthu kumatengera zamadzimadzi zomwe zimakhudzidwa, kutentha kwa magwiridwe antchito ndi zovuta, komanso zosowa zokana dzimbiri. Zida wamba ndi zitsulo zosapanga dzimbiri, mkuwa, ndi ma aloyi osiyanasiyana. Kusankhidwa kumafunika kuganiziridwa mozama kuti zitsimikizire kuti zimagwirizana komanso kukhala ndi moyo wautali.
Ubwino ndi Kuipa kwa Tube mu Tube Heat Exchangers
Ubwino wake
Osinthanitsa awa amadziwika ndi:
- Kuphweka kwa mapangidwe ndi zomangamanga.
- Zotsika mtengo.
- Kuyeretsa kosavuta ndi kukonza.
- Oyenera ntchito zothamanga kwambiri.
Zoipa
Zolepheretsa zina zomwe muyenera kuziganizira ndi izi:
- Malo otengera kutentha otsika pa voliyumu ya unit poyerekeza ndi mapangidwe ovuta kwambiri.
- Kugwiritsa ntchito kochepa pamitengo yotentha kwambiri.
- Kupezeka kwa kupsinjika ndi kupsinjika.
Kugwiritsa ntchito Tube mu Tube Heat Exchangers
Tube mu chubu chosinthira kutentha amagwiritsidwa ntchito m'mafakitale ambiri, kuphatikizapo:
- Chemical processing
- Kukonza zakudya ndi zakumwa
- Kupanga mankhwala
- Kupanga mphamvu
- Machitidwe a HVAC
Ntchito zenizeni nthawi zambiri zimaphatikizapo kutenthetsa kapena kuziziritsa zamadzimadzi kapena mpweya, monga kutenthetsa chakudya mu makina opangira mankhwala, kuthira mkaka pokonza chakudya, kapena kuziziritsa mafuta opaka m'makina. Kuphweka kwawo komanso kulimba kwawo kumawapangitsa kukhala okonda nthawi zambiri.
Kusankha ndi Kulingalira Mapangidwe
Mfundo Zofunika Kuziganizira
Kusankha zoyenera chubu mu chubu kutentha exchanger kumafuna kusanthula mosamala magawo angapo:
- Mayendedwe amadzimadzi
- Kusiyana kwa kutentha
- Kupanikizika kumatsika
- Zinthu zamadzimadzi (makamakamakamaka, matenthedwe matenthedwe, etc.)
- Kugwirizana kwazinthu
- Zofunika kutentha kutengerapo
Kuwerengera ndi Kukula
Kukula koyenera ndi kapangidwe kake kumafuna kugwiritsa ntchito kuwerengera kutentha, nthawi zambiri kumaphatikiza njira ya log mean kutentha (LMTD). Mapulogalamu apadera kapena mabuku opangira uinjiniya atha kuthandizira kuzindikira kukula ndi masinthidwe oyenera a pulogalamu yomwe wapatsidwa. Ndikofunikira kuphatikizira mainjiniya odziwa bwino ntchitoyi kuti awonetsetse kuti akugwira ntchito moyenera komanso motetezeka.
Kusamalira ndi Kuyeretsa
Kusamalira nthawi zonse ndikofunikira kuti mupewe kuipitsidwa ndi kukulitsa, zomwe zingachepetse magwiridwe antchito komanso moyo wautali. Kuphweka kwa mapangidwe ake kumapangitsa kuyeretsa kukhala kosavuta, nthawi zambiri kumaphatikizapo kupukuta ndi njira zoyenera zoyeretsera. Ndondomeko zoyendetsera bwino ndi ndondomeko ziyenera kukhazikitsidwa kuti zitsimikizidwe kuti zikuyenda bwino.
Zapamwamba kwambiri chubu mu chubu kutentha exchanger ndi kukaonana ndi akatswiri, ganizirani kulumikizana Malingaliro a kampani Shanghai SHENGLIN M&E Technology Co., Ltd. Ukatswiri wawo ndi kudzipereka kwawo kuzinthu zimatsimikizira njira zabwino zothetsera kutentha kwanu.
Zindikirani: Izi ndi zongowongolera chabe. Nthawi zonse funsani ndi mainjiniya oyenerera kuti mupeze mapangidwe apadera ndi zofunikira pakugwiritsa ntchito.
