Iluphi uhlobo lwesishintshi sokushisa olusebenza kahle kakhulu? - Ulwazi

I. Ukusebenza okuphezulu kakhulu kukonke: Isishintshi sokushisa se-plate (inketho evamile ekhethwayo)

Izishintshi zokushisa ze-plate zisebenzisa-amapuleti ensimbi anezindonga ezincane ukushintshanisa ukushisa. Isakhiwo sikathayela samapuleti siphoqelela uketshezi ukuthi lwakhe{2}}isiphithiphithi esikhulu, sibhidlize ngokuphelele ukumelana nokushisa emngceleni woketshezi. I-coefficient yabo yokudlulisa ukushisa ingafinyelela ku-1500-8000 W/(m²·℃), okuyizikhathi ezingu-2-5 kunezishintshi zokushisa zegobolondo neshubhu. Ngaphansi kwezidingo ezifanayo zokushintshanisa ukushisa, indawo yokushintshanisa ukushisa ingancishiswa ngaphezu kuka-60%, okuholela esivinini sokushintshaniswa kokushisa kanye nokusetshenziswa kokushisa okuphezulu.

1.I-Pure countercurrent heat exchange, ikhulisa ukusetshenziswa komehluko wokushisa

Okokusebenza kusebenzisa idizayini evumela ukuthi kuphikisane ngokuphelele-nokugeleza kwamanje kwemidiya eshisayo nebandayo, kanye nomehluko wetheminali wetheminali ophansi njengo-0.8℃. Lokhu kukhulisa umehluko wezinga lokushisa lokushintshaniswa kokushisa phakathi koketshezi olushisayo nolubandayo, kuqeda ukulahlekelwa ukushisa okungasebenzi, futhi kuzuza ukusebenza kahle kokushintshana kokushisa kwe-thermodynamic okudlula kude lokho okushintshisana ngokushisa okuhambisana{3}nezakhiwo zamanje noma ezixubile{4}}zokugeleza. Isilinganiso sokonga amandla sisonke singafinyelela ku-20% -50%.

2.I-Ultra-i-coefficient yokudlulisa ukushisa okuphezulu, umthamo wokushintsha ukushisa udlula kude okokusebenza kwendabuko

I-3.Isakhiwo esihlangene, ukusebenza kahle okuphezulu ngevolumu yeyunithi ngayinye

Izishintshi zokushisa ze-plate zinendawo yokushintsha ukushisa ngeyunithi ngayinye engu-3-izikhathi ezingu-5 kunezesheli-kanye-nezishintshi zokushisa zamashubhu, futhi zithatha kuphela u-1/3 wesikhala segobolondo elivamile{6}}kanye-nezishintshi zokushisa zeshubhu. Mancane ngosayizi futhi alula ngesisindo, okuwenza afanelekele okokusebenza okuncane naphakathi nendawo kanye nezimo zokufakwa kwe-modular phesheya kwezilwandle, kuyilapho kulinganisa ukusebenza kahle okuphezulu nokusetshenziswa kwendawo.

4.Operating Condition Imikhawulo

Ngenxa yokulinganiselwa kokusebenza kwama-gaskets okutywina, izishintshi zokushisa zamapuleti ezivamile zinezinga lokushisa elilinganiselwe nokumelana nokucindezela futhi azifanele izinga lokushisa eliphezulu{{0}eliphezulu,{1}}ukucindezela okuphezulu, noma{2}}izimo zemidiya ze-viscous zokungcola okuphezulu. Zifanele kuphela ukushintshaniswa kokushisa ngamanzi ahlanzekile, amafutha alula, neziqandisi ezivamile.

II. Inguqulo-esebenza kahle kakhulu yezimo ezikhethekile zokusebenza: Isishintshi sokushisa se-Spiral plate

Izishintshi zokushisa zamapuleti e-Spiral zisebenza kahle kakhulu okwesibili kuphela kumapuleti okushintshanisa ukushisa. Nge-viscous, ukungcola kalula, kanye nemidiya equkethe ukungcola okulandela umkhondo, ukusebenza kahle kwazo nokuzinza kuphakeme kunezishintshi zokushisa zamapuleti, okuzenza zibe ukukhetha okusebenza kahle kakhulu ezimeni ezikhethekile zezimboni.

1. Isiyaluyalu esinamandla sivimbela ukukala futhi siqinisekisa ukusebenza{1}}okuseqophelweni eliphezulu okuqhubekayo.

Idizayini ekabili-yesiteshi sokuvunguza ivumela uketshezi ukuthi lujikeleze futhi lugeleze ngesivinini esiphezulu kuyo yonke inqubo, okuholela ekunyakazeni okuzinzile futhi kuvimbele ukunqwabelana kokungcola. Izinga lokunqwabelana kokungcola lingaphansi ngo-70% kunelo legobolondo-kanye-nohlobo lweshubhu, futhi ukusebenza kahle ngeke kwehle ngenxa yokukala phakathi{5}}nokusebenza kwesikhathi eside, okulenza lifanele{6}}isikhathi eside{6} sokusebenza okuqhubekayo.

2.Ukusebenza kahle kokushintshisana kokushisa kungaphezu kwalokho kwegobolondo elivamile-kanye{2}}nezinhlelo zamashubhu.

Futhi yamukela ikhawunta egcwele-isakhiwo samanje sokushintsha ukushisa, esine-coefficient yokudlulisa ukushisa ephakeme ngo-50% -100% kunaleyo yamagobolondo avamile nezishintshi zokushisa zamashubhu. Inokushintshaniswa kokushisa okwanele nokulahlekelwa ukushisa okuphansi, futhi yenza kahle kakhulu mayelana nokusebenza kahle kwamandla kumakhemikhali, ukuphrinta nokudaya, kanye nezimo zokushintshanisa ukushisa kwamanzi angcolile.

III. Okuvamile{1}}uhlobo lwenhloso evamile: igobolondo nesishintshi sokushisa seshubhu (ukusebenza kahle okumaphakathi, kulungele izimo zokusebenza ezidlulele)

I-Shell-kanye-nezishintshi zokushisa zamashubhu ziwuhlobo lwakudala lwezimboni olunesabelo esikhulu semakethe, kodwa ukusebenza kahle kwazo kokushintshaniswa kokushisa kuphansi kakhulu kunalokhu kwamapuleti kanye nezishintshi zokushisa ze-spiral plate. Inzuzo yabo kuphela ukushisa kwabo okuphezulu nokumelana nokucindezela nokuzinza okuqinile.

1 Ukusebenza kahle kokushintshanisa ukushisa okuphansi

Ukugeleza koketshezi kunokunyakaza okubuthakathaka, ipayipi eliphakeme ukumelana nokushisa kodonga, kanye nokusetshenziswa komehluko wokushintshaniswa kokushisa okuphansi. I-coefficient yokudlulisa ukushisa evamile ingu-300-800W/(m²·℃kuphela). Ngaphansi kwezidingo ezifanayo zokushintshanisa ukushisa, okokusebenza kukhulu, isikhathi sokushintshanisa ukushisa side, futhi ukusetshenziswa kwamandla kuphezulu.

Amandla we-2.Core anxephezela ukushiyeka kokusebenza kahle

Ingakwazi ukumelana nezinga lokushisa eliphezulu, ukucindezela okukhulu, ukugqwala okuqinile kanye nemidiya yokungcola okuphezulu, futhi ifanele izimo zokusebenza ezidlulele ezimbonini ezinzima ezifana ne-petrochemical, amandla, kanye ne-metallurgy. Iwukuphela kwenketho yokucindezela okuphezulu nezimo zokushisa okuphezulu. Inzuzo yayo eyinhloko ayikona ukusebenza kahle okuphezulu, kodwa ukuzinza nokusebenziseka.
