I-ASME SA179 iyindinganiso yepayipi lensimbi elingenamthungo le-heat exchanger elakhiwe yi-American Society of Mechanical Engineers (ASME), ecacisa izinkomba ezibalulekile njengenqubo yokukhiqiza, ukwakheka kwamakhemikhali, izakhiwo zemishini kanye nokubekezelelana kobukhulu bepayipi. Leli zinga liqinisekisa ukuthi ipayipi lensimbi linokumelana okuhle kakhulu nokucindezela, ukuhanjiswa kokushisa kanye nokumelana nokugqwala kuma-heat exchanger ahlukahlukene, futhi lifanele izimo zokusebenza ezinzima ezimbonini zamakhemikhali, zamandla, zokudla kanye nezinye izimboni.
Izinzuzo eziyinhloko zenqubo yokudweba ebandayo
Ipayipi elijwayelekile laseMelika elidonswa ngokubandayo elingenamthungo lisebenzisa ubuchwepheshe bokudweba izinga lokushisa legumbi futhi lakhiwe ngokunembile yizikhunta. Linezici ezilandelayo:
Usayizi onembile kakhulu: ukubekezelelana okuqinile kobubanzi bangaphandle (njengo-± 0.10mm), ubukhulu bodonga obufanayo, obufanele isakhiwo se-heat exchanger esivala kakhulu.
Ukuqinisa izakhiwo zemishini: ukuguqulwa okubandayo kwenza okusanhlamvu kugxile, kuthuthukisa amandla okunamathela (≥325MPa) kanye nokuqina, kuyilapho kugcinwa ukuqina okuhle.
Ikhwalithi ephezulu kakhulu yobuso: udonga lwangaphakathi olubushelelezi (ubulukhuni be-Ra≤0.8μm), kunciphisa ukumelana noketshezi, futhi kuthuthukisa ukusebenza kahle kokushintshana kokushisa.
Imininingwane yosayizi wokhiye
I-ASME SA179 ihlanganisa imininingwane eyahlukahlukene ukuze ihlangabezane nezidingo zezimo ezahlukene zokushintshana kokushisa:
Ububanzi bobubanzi bangaphandle (mm) Ububanzi bokujiya kodonga (mm) Izimo ezijwayelekile zokusetshenziswa
12.7~25.4 1.24~2.11 Isishintshi sokushisa sepuleti elincane
25.4~38.1 2.11~3.81 I-Chemical shell kanye ne-tube heat exchanger
38.1~50.8 3.81~5.59 I-condenser yesiteshi sikagesi enomfutho ophezulu
Amacala okusebenza embonini
1. Imboni yamakhemikhali
Ukuhluzwa kwe-petroleum: Amashubhu okushintshanisa ukushisa asetshenziswa kuma-reactor e-hydrogenation, amelana nokugqwala kwe-hydrogen sulfide (ukuhlushwa kwe-H₂S ≤50ppm).
Ukukhiqizwa kwe-asidi ye-sulfuric: Igesi ye-SO₂ epholile enokushisa okuphezulu (≤450℃), ukugqoka okulwa nokugqwala kuyadingeka uma usebenzisa insimbi yekhabhoni.
2. Amandla kagesi
Amapayipi e-Condenser: Ezitshalweni zamandla ezishisayo, amapayipi ensimbi e-SA179 amelana nomfutho womusi ongu-0.1MPa, kanye nokuqhuba kokushisa okungu-50W/(m·K), kanye nokwenyuka kokusebenza kahle kokuqina kokuqina okungu-15%.
