Thaum tshav kub kub exchangers thiab tshav kub exchangers tuaj yeem daws tau los ntawm lwm txoj hauv kev ntxiv rau kev siv tshwj xeeb ZS ceramic los tiv thaiv corrosion los tiv thaiv corrosion thiab ncua lawv lub neej kev pab cuam.
Muaj ib hom kev tiv thaiv corrosion uas tuaj yeem tiv taus lub sijhawm ntev rau hauv cov kuab tshuaj muaj zog thiab cov kuab tshuaj sib xyaw, oxidation corrosion ntawm concentrated sulfuric acid thiab hydrochloric acid, corrosion ntawm cov kua qaub muaj zog, corrosion ntawm high-temperature chlorine gas, corrosion ntawm hydrogen gas. , corrosion ntawm high-temperature seawater, thiab waterproofing thiab corrosion kuj ntawm 1000 degree. Tsis tas li ntawd, cov txheej txheem tiv thaiv corrosion no muaj kev hnav zoo thiab kev tu tus kheej. Nws tuaj yeem hu ua qhov muaj zog tshaj plaws los tiv thaiv corrosion txheej ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob hauv ntiaj teb.
Cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tuaj yeem daws tau los ntawm lwm txoj hauv kev ntxiv rau kev siv tshwj xeeb ZS ceramic los tiv thaiv corrosion los tiv thaiv corrosion thiab ncua kev pab cuam lub neej. ① Txo cov corrosiveness ntawm qhov nruab nrab tuaj yeem ua tiav los ntawm kev tshem tawm cov pa oxygen thiab oxidants los ntawm nruab nrab los tswj kev ntxhov siab corrosion, txo cov concentration ntawm Cl - hauv nruab nrab, thiab nruj me ntsis tswj cov concentration ntawm sulfur nyob rau hauv nruab nrab kuj yog ib qho zoo. ntsuas los tswj kev ntxhov siab corrosion. ② Txhim kho cov qauv thiab cov qauv ntawm lub tshav kub exchanger. Txhawm rau kom tsis txhob muaj cov kua qaub thiab cov khib nyiab pov tseg, ob lub taub qab vuam thiab txuas txuas txuas ntxiv yuav tsum tau siv ntau li ntau tau thaum vuam, tsis txhob siv cov hlua khi thiab qhov chaw vuam. Nyob rau hauv cov txheej txheem vuam, vuam hlau yuav tsum tau sau 100% kom ntseeg tau zoo weld tsim Txo qhov seem ntawm kev ntxhov siab, raws li kev ua tau zoo, qhov kev ntxhov siab tseem ceeb ua rau muaj kev ntxhov siab corrosion tawg yog qhov seem ntawm kev ntxhov siab, uas yog tsim los ntawm kev ntxhov siab sab hauv los ntawm kev ua haujlwm txias thiab vuam. . Kev kho cua sov ntawm kev ua haujlwm txias thiab cov khoom siv welded pab tshem tawm cov kev ntxhov siab seem, yog li tseem tiv thaiv qhov tshwm sim ntawm kev ntxhov siab corrosion. Kev ntxhov siab annealing kev kho cua sov lossis lwm txoj hauv kev los tshem tawm cov kev ntxhov siab uas nyob hauv feem ntau yog siv, xws li kev sim hydraulic, kev co kev laus, thiab hammering Electrochemical tiv thaiv txoj kev, kev ntxhov siab corrosion tawg yog txheej txheem anodic dissolution nyob rau hauv kev ntxhov siab. Yog li ntawd, kev tiv thaiv electrochemical tuaj yeem siv los tswj. Txoj kev tiv thaiv electrochemical tuaj yeem tsis tsuas yog tiv thaiv kev ntxhov siab corrosion tawg, tab sis tseem txwv tsis pub kev nthuav tawm ntawm cov kab nrib pleb txawm tias qhov kev tiv thaiv tsis raug xaiv kom tsim nyog. Sacrificial anode tiv thaiv los yog nto txau ntawm corrosion-resistant hlau yuav siv tau Ntxiv corrosion inhibitors los tiv thaiv kev nyuaj siab corrosion cracking ntawm stainless hlau los ntawm qhov tshwm sim nyob rau hauv lub activation muaj peev xwm cheeb tsam, uas yuav tsum tau them nrog adsorption hom corrosion inhibitors. Txoj kev sib sau ua rau cov yeeb yaj kiab adense adstorption zaj duab xis ntawm cov hlau nto suppresses ntawm cov txheej txheem corrosion. 6. Kev ntxuav cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tau pom zoo los ntawm Beijing Zhisheng Weihua los tiv thaiv corrosion txheej kws tshaj lij. Circulating tu yuav siv tau los ntxuav lub tshav kub exchanger thiab tshav kub exchanger, thiab cov tshuaj ntxuav yuav tsum pumped mus rau hauv lub circulating dej system rau kev. Txoj kev no muaj kev tu zoo dua ntawm daim hlau tom qab scaling. Qhov thib ob txoj kev yog disassemble thiab huv si. Yog hais tias cov channel ntawm cov cua kub exchanger raug thaiv los ntawm impurities, lawv yuav tsum tau disassembled thiab ntxuav ib tug los ntawm ib tug. Kev ntxuav ntawm cov khoom siv hluav taws xob feem ntau siv cov tshuaj ntxuav tes uas muaj zog nkag, tev tawm, ntxuav, thiab muaj peev xwm tiv thaiv corrosion. Kev kho ua ntej ua haujlwm tu tuaj yeem txo qhov kev raug mob corrosion zoo heev.
