Umdwebo wesakhiwo wezinhlaka ezahlukahlukene zokushintsha umzimba

Ihlukaniswe ngendlela yokudlulisa ukushisa: ukushisa kokushisa kungahlukaniswa kube ukushintshana kokushisa, ukushisa kokugcina ukushisa, okokushisa okungaxhunywanga okungaxhumi okokushisa, okokushisa okuxhumana okuqondile, kanye nokuhwebelana okuningi kokushisa;

Ihlukaniswe ngenhloso: ihlukaniswe yaba yi-heater, i-preheater, i-superheater, i-evaporator;

Ngokusho kwesakhiwo, ingahlukaniswa: okushisa okushisa okushisayo kwekhanda, ishubhu elishisayo lokushisa ukushisa, i-U-shaped tube sheet ukushisa ukushisa, ipuleti lokushisa ukushisa njalonjalo.

1. Isishintshisi sokushisa ekhanda esintantayo

Izinzuzo: Kuqeda ukucindezela komehluko wokushisa, kungasebenza ngaphansi kokushisa okuphezulu nokucindezela okukhulu, imvamisa izinga lokushisa lingaphansi noma lilingana nama-degree angama-450, ingcindezi ingaphansi noma ilingana no-6.4 MPa; Isigaxa seshubhu esishintsha ukushisa singakhishwa ukuze sihlanzwe, futhi singasetshenziswa ezimeni ezijwayele ukukala noma lapho ishubhu livame ukugqwala.

Ububi: Isakhiwo siyinkimbinkimbi, futhi ikhanda elincane elintantayo livame ukuvuza ngaphakathi. Ukusetshenziswa kwezinto zensimbi kukhulu, futhi izindleko ziphakeme cishe ngama-20% kunalezo ezijwayelekile zokushisa okushisa.

2. Ishubhu eshubisa umzimba sokushisa

Izinzuzo: isakhiwo esilula futhi esihlangene, izindleko eziphansi;

Okubi: Ingaphandle leshubhu alikwazi ukuhlanzwa ngomshini, futhi kunomehluko omkhulu wokushisa phakathi kodonga lweshubhu nodonga lwegobolondo;

3. U-tube wokushisa ukushisa

Izinzuzo: isigaxa sethubhu singanwetshwa futhi sitholakale ngokukhululekile, akukho ukucindezeleka okushisayo phakathi kweshubhu negobolondo, ukudlula kweshubhu kungukuphasa kwamapayipi kabili, inqubo yinde, umphumela wokushintshana ngokushisa muhle, nomthamo wokuthwala ingcindezi unamandla; isishuqulu seshubhu singakhishwa kugobolondo, esilungele ukugcinwa nokuhlanzwa, futhi sinesakhiwo esilula nezindleko eziphansi;

Okubi: ukuhlanza okungahambi kahle kushubhu, kunzima ukufaka amashubhu maphakathi kwesigaxa seshubhu, ukusatshalaliswa kwamashubhu akuhlanganisi ngokwanele, uketshezi lwecala legobolondo kulula ukulenza lifushane futhi kuthinte ukudluliswa kokushisa kwegobolondo, ithubhu lizogobeka futhi libe mncane, ngakho-ke ingxenye eqondile yeshubhu idinga ithubhu ekhudlwana, okuyikhawulelayo Isishintshisi sokushisa silungele kuphela izikhathi lapho umehluko wezinga lokushisa phakathi kweshubhu nohlangothi lwegobolondo likhulu, noma indawo eseceleni kwegobolondo kulula isikali nendawo eseceleni kwethubhu ihlanzekile, izinga lokushisa eliphakeme, umfutho ophakeme, nokubola okuqinile;

4. Ukucwilisa ukushisa kwekhoyili

Ngebhubhu le-serpentine njengesici sokudlulisa ukushisa, ngokusho kwezindlela ezahlukahlukene zokupholisa ketshezi ngaphandle kweshubhu, umshini wokushisa wenyoka uhlukaniswe waba uhlobo lokucwiliswa nohlobo lwesifutho.

Izinzuzo: ukwakheka okulula, ukukhiqiza okulula, ukufakwa, ukuhlanza, ukuhlolwa nokugcinwa, kuvikela ukuvikelwa kokugqwala, ukuthwala umfutho ophakeme, izindleko eziphansi, ikakhulukazi ezifanele ukupholisa okuphezulu kwengcindezi kanye nokujiya.

Okumbi: okokusebenza kukhulu, okudlekayo kukhulu, futhi ukudluliswa kokushisa kweyunithi kudinga insimbi eningi;

5.Casing uhlobo ukushisa

Izinzuzo: indawo enkulu yokushintshanisa ukushisa nokusebenza kahle kokushisa kokushisa;

Okungalungile: ukugcinwa okunenkathazo, ukuhlanza nokuqaqa, futhi kulula ukudala ukuvuza ekuxhumekeni okutholakalayo;

6. Isishintshisi sokushisa sepuleti esivunguza

Izinzuzo: ukusebenza kahle kokudlulisa ukushisa, ukusebenza okuzinzile, amayunithi amaningi angasetshenziswa, ukusebenza kahle kokudlulisa ukushisa, ukuthembeka kokusebenza okuqinile, ukumelana okuphansi, njll.

Okungalungi: izidingo eziphezulu zekhwalithi ye-welding, ukugcinwa okunzima, isisindo esinzima, ukuqina okungahambi kahle, nokuhamba okunzima nokufakwa;

7. Isishintshisi sokushisa ngendandatho yesinxephezelo

Lapho uketshezi kushintshana ngokushisa okuphezulu, ukucindezela okushisayo ohlangothini lwe-tube ne-shell kukhulu kakhulu, futhi indandatho yokuqinisa (noma i-joint joint) ingaqeda ukucindezela okushisayo. Izinga elihlukile lokunweba lokushisa kweshubhu, lilungele isikhathi lapho umehluko wezinga lokushisa phakathi kuketshezi ezimbili ungekho ngaphezu kuka-70 ℃ kanye nengcindezi ye-shell side fluid ayidluli ku-600kPa.

8. Ishisa ipayipi lokushisa

Izici: Ukusebenza kahle kokudluliswa kokushisa, isakhiwo esihlanganisiwe, ukulahleka okuncane kokushisa kokushintshana kokushisa, ukuguquka kwesimo okuguquguqukayo, ukumelana nokugqwala, nokuguquguquka kwemvelo okuqinile.

9. Isishintshisi sejacketed heat

Izinzuzo: isakhiwo esilula, ukukhiqiza okulula nokuhamba;

Okubi: Indawo yokudlulisa ukushisa inqunyelwe, futhi i-coefficient yokudlulisa ukushisa ayiphezulu. I-stirrer noma i-coil ingangezelwa ukukhulisa i-coefficient yokudlulisa ukushisa;

10. Plate-fin ukushisa

Izinzuzo: isakhiwo esihlanganisiwe nesingasindi, ukushisa okuphezulu kokudlulisa ukushisa, ukusebenza okuqinile;

Okumbi: izidingo eziphezulu zokukhiqiza, inqubo eyinkimbinkimbi, evimba kalula, engamelani nokugqwala, okunzima ukuyihlola nokulungisa, ngakho-ke kufanelekile kuphela ekuhlanzeni iziphuzo;
