Volumetric kub exchangerstau dav siv rau kev hloov pauv hluav taws xob zoo thiab ruaj khov hauv ntau daim ntawv thov kev lag luam. Txhawm rau txhim kho lawv lub neej kev pabcuam thiab kev nyab xeeb ntawm kev ua haujlwm, kev txhim kho kev lag luam yog qhov tseem ceeb. Hauv qab no yog cov lus piav qhia ntxaws ntawmkev hloov kho tshuablos tiv thaiv corrosion cracking thiab cov txheej txheem rau kev txiav txim seb lub Volumetric tshav kub exchanger ntog nyob rau hauv lub Scope ntawm ib tuglub nkoj siab.
Kev Txhim Kho Kev Txhim Kho rau Volumetric Kub Exchangers
Txhawm rau tiv thaiv corrosion-induced cracking, cov kev ntsuas hauv qab no tuaj yeem siv tau:
Kev Tswj Xyuas Khoom Zoo
Ua nruj me ntsis tswj qhov zoo ntawm cov khoom siv raw.
Ntxivstabilizing cov ntsiab luslos yog txo cov ntsiab lus ntawm cov pa roj carbon monoxide kom txo qis ciam teb adsorption thiab carbide nag lossis daus.
Xyuas kom meej tiasheat-kho qhov kub, lub sijhawm, thiab tus nqi txiasUa tau raws li cov kev qhia tshwj xeeb kom txo tau cov dej nag los ntawm chromium carbide, ua kom zoo dua cov nplej loj, thiab txo qis kev cuam tshuam rau corrosion.
Kev tsim qauv tsim kom zoo
Zamqhov chaw kaw los yog nyob ruaj khovqhov twg corrosive media tuaj yeem sau.
Thaum lub sij hawm tsim, kaw qhov khoob ntawm cov ntawv raj thiab cov raj;foob vuamua raws listress-kev kho mobpom zoo.
Txheej Txheem Nruab Nrab Tswj
nruj me ntsis txwv impurities-tshwj xeebchloride ion (Cl⁻) concentration- mus rau theem qis dua cov uas ua rau muaj kev ntxhov siab corrosion tawg.
Siv cov tshuaj kho mob lossis cov txheej txheem lim kom tswj tau dej chemistry nyob rau hauv qhov txwv tsis pub muaj kev nyab xeeb.
Xaiv cov khoom siv
Cov paCr-Ni austenitic stainless hlauua rau muaj kev ntxhov siab ntau dua tom qab ua haujlwm kub lossis vuam vim tias cov nyhuv stabilizing ntawm titanium (Ti) ploj zuj zus, ua rau nplej - ciam teb rhiab heev thiab txo cov kev cuam tshuam ntawm intergranular corrosion.
Lub siab- kev lag luam nkoj tau tshem tawm cov qib steel ntau heev.
Cov kev xaiv uas nyiam suav nrogqis- carbon Cr–Ni austenitic stainless hlauxws li0Cr18Ni10 Ti, 0Cr18Ni11 Nb, los yogultra- qis- carbon 00Cr19Ni10 stainless hlau, uas txo qhov kev pheej hmoo ntawm nplej - ciam teb rhiab heev.
Duplex stainless hlauyog lwm qhov kev xaiv kom txo tau cov tshuaj chloride kev nyuaj siab corrosion cracking.
Cov txheej txheem rau Classifying Volumetric Heat Exchangers raws li lub nkoj siab
Raws li cov cai ntawm lub nkoj siab kawg, Volumetric thiabsemi- khaws cia- hom kub exchangerspoob rau hauv qhov kev tshuaj ntsuam xyuas thaum muaj xwm txheej tshwj xeeb. Txhawm rau txiav txim siab seb lub tsev puas tsim nyog raws li lub nkoj siab, ntsuas cov hauv qab no raws li Tshooj 1.3 ntawm "Pressure Vessel Code":
Chav-Dej (Gas-Liquid) Thaum tshav kub kub Exchanger
Yog tiascev sabmuaj saturated chav, lub exchanger yuav tsumunconditionallyraug cais raws li lub nkoj siab.
- Dej- Dej Txias Txias
Muaj ob qhov xwm txheej:
(a) Yog tiastube-sab dej kub kub nce mus txog tus qauv boiling point, lub unityuav tsum tau muab caisraws li lub nkoj siab.
(b) Yog hais tiastube- sab dej kub kub tsis ncav cuag qhov kub kub, classification yogtsis xav tau-tsuas yog tusplhaub sab muaj ib theem rojthiab ua tau raws li cov cai ntawm Tshooj 1.3(3), nyob rau hauv cov ntaub ntawv nwsyuav tsum suav nrog.
- Tshem Tawm Tube Box lossis Tube -Sab Ntug
Yog tias lub thawv raj lossis lub raj - sab sab raug tshem tawm, kev faib tawm tseem nyob ntawmkubthiabmuaj roj theem.
Thaum xam lub plhaub- sab ntim los txiav txim qhov kev faib tawm,txiav tawm lub ntim ntim los ntawm cov cua sov- pauv cov rajlawv tus kheej.
Los ntawm nrujxaiv cov khoom siv, kev txhim kho cov qauv, thiabtxheej txheem- tswj nruab nrab, cia- hom hluav taws kub exchangers tuaj yeem ua tau zoo dua rau kev ntxhov siab corrosion cracking. Kev nkag siab txog cov txheej txheem kev cai rau kev faib cov hlab ntsha siab kom ua raws li cov qauv kev nyab xeeb thiab txhim khu kev qha ntev - lub sijhawm ua haujlwm.
Ntxiv nrog rau qhov ntsuas kub ntsuas, GNEE tseem muaj ntau dua - cov khoom zoo, xws li lub plhaub- thiab - raj kub exchangers, tooj liab kub exchangers, titanium tshav kub exchangers, cua sov, chlorine coolers, siab - siab reactors, LPG cia tso tsheb hlau luam, cryogenic cia tso tsheb hlau luam, VPSA cov khoom, thiab lwm yam. pub dawb xa email rauglobal@gneesteels.com, thiab peb pab neeg tshaj lij yuav zoo siab los teb koj cov lus nug.
