I-Tube in Tube Heat Exchangers: Umhlahlandlela OpheleleLe ndatshana ihlinzeka ngemininingwane eminingi ishubhu kumashubhu okushintshanisa ukushisa, ukuhlola ukwakheka kwazo, izinhlelo zokusebenza, izinzuzo, ububi, kanye nemibandela yokukhetha. Sihlolisisa izinhlobo ezahlukene, izinto zokwakha, kanye nezibalo, sinikeza imininingwane esebenzayo yonjiniyela nochwepheshe abasebenza ngamasistimu okudlulisa ukushisa.
Ishubhu kumashubhu okushintshanisa ukushisa, owaziwa nangokuthi izishintshi zokushisa zamapayipi amabili, ziphakathi kwezinhlobo ezilula neziyisisekelo kakhulu zezishintshisi zokushisa. Zisetshenziswa kabanzi ezimbonini ezahlukahlukene zokudlulisa ukushisa okusebenzayo phakathi koketshezi olubili. Lo mhlahlandlela uzokusiza uqonde ukusebenza kwawo, ukucatshangelwa kwedizayini, kanye nezicelo ezingokoqobo. Sizophinde sixoxe ngenqubo yokukhetha, sicabangela izici ezifana namazinga okugeleza, ukuhluka kwezinga lokushisa, nokwehla kwengcindezi. Ukuqonda lezi zakhi kubalulekile ekusebenzeni okuhle nokuthembeka kwesikhathi eside.
Ukuqonda Okuyisisekelo Kweshubhu ku-Tube Heat Exchangers
Ukuklama Nokwakha
A ishubhu kusishintshi sokushisa se-tube inamashubhu amabili agxilile, elilodwa ngaphakathi kwelinye. Uketshezi lugeleza ngeshubhu elingaphakathi, kuyilapho uketshezi lwesibili lugeleza esikhaleni esiphakathi kwamashubhu angaphakathi nangaphandle. Ukudluliswa kokushisa kwenzeka ngodonga lwamashubhu, olwenziwa ukuqhutshwa nokuhamba. Uketshezi lungageleza ngokwe-co-current (inkomba efanayo) noma ye-counter-current (inkombandlela ephambene), ngokugeleza kwamanje okuphikisayo ngokuvamile okunikeza ukusebenza kahle okuphezulu.
Izinhlobo ze-Tube ku-Tube Heat Exchangers
Ukwehluka kukhona kuye ngohlelo oluthile kanye nezidingo. Lokhu kubandakanya:
- Izishintshi zokushisa ze-single-pass: Uketshezi lugeleza kanye kumashubhu afanele.
- Izishintshi zokushisa zamaphasi amaningi: Uketshezi ludlula izikhathi eziningi kumashubhu, okwandisa ukusebenza kahle kokudlulisa ukushisa. Lokhu kungase kuhlanganise ama-U-turn noma okunye ukulungiselelwa.
- Ngokudideka noma ngaphandle kokudideka: Ama-Baffles angathuthukisa isiyaluyalu futhi andise ukudluliswa kokushisa, kodwa futhi angakhuphula ukwehla kwengcindezi.
Izinto zokwakha
Ukukhethwa kwezinto kuncike emanzini ahilelekile, amazinga okushisa okusebenza nezingcindezi, kanye nezidingo zokumelana nokugqwala. Izinto ezivamile zihlanganisa insimbi engagqwali, ithusi, nama-alloys ahlukahlukene. Ukukhetha kudinga ukucatshangelwa ngokucophelela ukuze kuqinisekiswe ukuhambisana nokuphila isikhathi eside.
Izinzuzo kanye Nobubi be-Tube ku-Tube Heat Exchangers
Izinzuzo
Lawa ma-exchange aziwa ngalawa:
- Ubulula bokuklama nokwakha.
- Izindleko eziphansi uma kuqhathaniswa.
- Ukuhlanza okulula nokugcinwa.
- Ifanele izinhlelo zokusebenza ezinomfutho ophezulu.
Ukubi
Eminye imikhawulo okufanele icatshangelwe ihlanganisa:
- Indawo yokudlulisa ukushisa ephansi ngokulinganayo ngevolumu yeyunithi ngayinye uma iqhathaniswa nemiklamo eyinkimbinkimbi.
- Ukusebenza okulinganiselwe kwamazinga aphezulu kakhulu okudlulisa ukushisa.
- Okungenzeka kube nokubi nokukala.
Izicelo ze-Tube ku-Tube Heat Exchangers
Ishubhu kumashubhu okushintshanisa ukushisa zisetshenziswa ezimbonini eziningi, okuhlanganisa:
- Ukucubungula amakhemikhali
- Ukucubungula ukudla nesiphuzo
- Ukukhiqizwa kwemithi
- Ukukhiqiza amandla
- Amasistimu we-HVAC
Izinhlelo zokusebenza ezithile ngokuvamile zihlanganisa ukushisisa noma ukupholisa uketshezi noma amagesi, okufana nokushisisa kusengaphambili i-feedstock kureactor yamakhemikhali, ukufakwa kobisi ekucutshungulweni kokudla, noma ukupholisa amafutha okugcoba emishinini. Ubulula nokuqina kwabo kubenza babe ukukhetha okuthandwayo ezimeni eziningi.
Ukukhetha Nokucatshangelwa Kwedizayini
Izinto Okufanele Zicabangele
Ukukhetha ezifanele ishubhu kusishintshi sokushisa se-tube idinga ukuhlaziya ngokucophelela amapharamitha ambalwa:
- Amazinga okugeleza kwamanzi
- Umehluko wezinga lokushisa
- Ingcindezi iyehla
- Izakhiwo ze-Fluid (i-viscosity, i-thermal conductivity, njll.)
- Ukuhambisana kwezinto
- Izinga lokudlulisa ukushisa elidingekayo
Ukubala kanye nosayizi
Ukulinganisa okufanelekile nokuklama kudinga ukusetshenziswa kwezibalo zokudlulisa ukushisa, ngokuvamile okubandakanya indlela ye-log mean lokushisa umehluko (LMTD). Isofthiwe eyisipesheli noma izincwadi zezandla zobunjiniyela zingasiza ekunqumeni ubukhulu nokulungiswa kohlelo olunikeziwe. Kubalulekile ukubandakanya onjiniyela abanolwazi kule nqubo ukuze kuqinisekiswe ukusebenza kahle nokuphephile.
Ukunakekela Nokuhlanza
Ukunakekelwa okuvamile kubalulekile ukuze kuvinjelwe ukungahambi kahle kanye nokukala, okunganciphisa ukusebenza kahle nempilo yokuphila. Ubulula bomklamo kwenza ukuhlanza kuqonde, ngokuvamile kuhilela ukuhlanza ngezixazululo ezifanele zokuhlanza. Kufanele kusungulwe amashejuli nezinqubo zokugcinwa okufanele ukuze kuqinisekiswe ukusebenza kahle.
Ngekhwalithi ephezulu ishubhu kumashubhu okushintshanisa ukushisa kanye nokubonisana nochwepheshe, cabanga ukuxhumana I-Shanghai SHENGLIN M&E Technology Co., Ltd. Ubuchwepheshe babo nokuzibophezela kwabo kwikhwalithi kuqinisekisa izixazululo eziphelele zezidingo zakho zokudlulisa ukushisa.
Qaphela: Lolu lwazi olokuqondisa okuvamile kuphela. Hlala uthintana nonjiniyela abaqeqeshiwe mayelana nedizayini ethile kanye nezidingo zohlelo lokusebenza.
