High-Density Cartridge rhaub nyob rau hauv kev ua tshuaj: Corrosion Resistance thiab Safety

Kev ua tshuaj siv ntau yam sib txawv, muaj tshuaj lom, lossis siab - cov khoom kub, xws li cov kua qaub, alkalis, cov kuab tshuaj, thiab cov ntsev molten. Vim tias qhov chaw no hnyav npaum li cas, cov kev daws teeb meem cua sov yuav tsum muaj kev nyab xeeb, corrosion- tiv taus, thiab ua haujlwm tau zoo thiab raug. High-High Cartridge rhaub yog ib qho kev xaiv nrov rau kev ua tshuaj lom neeg vim tias lawv muaj cov ntaub ntawv sheathable, tswj qhov kub thiab txias, thiab me me. Lawv zoo dua li lwm cov kev xaiv cua sov, xws li cov cua sov hluav taws xob (uas tsis tiv taus corrosion) lossis boilers (uas loj thiab qeeb). Lawv muab cov cua sov txhim khu kev qha txawm nyob rau hauv cov xwm txheej xav tau tshuaj lom neeg.

Kev ua tshuaj lom neeg xav tau siab -cov khoom siv hluav taws xob ceev uas tiv taus corrosion. Vim tias lub tshuab cua sov lub plhaub yog nyob ze nrog cov xov xwm corrosive, kev siv cov khoom tsis tsim nyog rau lub tsho yuav ua rau nws corrode sai, xau, thiab ua tsis tiav, uas tuaj yeem ua rau muaj kev phom sij heev (piv txwv li, cov khoom tawg, luv luv, lossis hluav taws kub). Raws li qhov kuv tau pom, nyob ib ncig ntawm 60% ntawm cov cua sov ua tsis tiav hauv kev ua tshuaj lom neeg yog tshwm sim los ntawm corrosion los ntawm cov ntaub ntawv sheath uas tsis ua haujlwm zoo ua ke. Yog li, xaiv cov ntaub qhwv ntaub kom raug yog thawj kauj ruam los ua kom muaj kev nyab xeeb thiab kev ntseeg tau.

316L stainless hlau, Incoloy 800/840, thiab Hastelloy C-276 yog cov ntaub ntawv siv ntau tshaj plaws rau siab-cov khoom siv hluav taws xob ntom ntom ntom ntom ntom ntom siv hauv kev ua tshuaj lom neeg. 316L stainless hlau ua haujlwm zoo nyob rau hauv ib puag ncig me me mus rau nruab nrab corrosive ib puag ncig, zoo li cov acids tsis muaj zog, hauv paus, thiab dej hiav txwv. Nws muaj molybdenum nyob rau hauv nws, uas ua rau nws tsis tshua muaj xeb, thiab nws muaj peev xwm tuav kub txog 650 degree. Cov khoom siv no yog pheej yig thiab ua haujlwm zoo nyob rau hauv cov xwm txheej uas cov xov xwm tsis yog corrosive heev, xws li cua sov tshuaj tov uas yog dej.

Incoloy 800/840 yog ib qho alloy ntawm npib tsib xee, hlau, thiab chromium uas tiv taus corrosion los ntawm ntau yam tshuaj, xws li muaj zog acids, bases, thiab molten ntsev. Nws tuaj yeem tswj tau qhov kub txog li 850 degree, yog li nws yog qhov zoo rau kev siv tshuaj uas yuav tsum tau kub, xws li cua sov sulfuric acid lossis nitric acid. Incoloy raug nqi ntau dua 316L stainless hlau, tab sis nws kav ntev dua thiab ua haujlwm zoo dua hauv cov xwm txheej nyuaj.

Hastelloy C-276 yog cov khoom siv sheath uas tsawg kawg yuav corrode. Nws yog tsim rau cov tshuaj lom neeg nyuaj tshaj plaws. Nws tuaj yeem tiv taus yuav luag txhua yam corrosive, xws li muaj zog hydrochloric acid, hydrofluoric acid, thiab chlorine gas. Nws tuaj yeem tswj tau qhov kub txog li 750 degree, uas ua rau nws zoo meej rau cov kws tshaj lij siv xws li refining petrochemicals lossis ua cov tshuaj siv tshuaj. Hastelloy yog qhov kev xaiv kim tshaj plaws, tab sis nws yog qhov tsim nyog rau cov xwm txheej uas corrosion yog qhov teeb meem loj.

Lwm qhov tseem ceeb ntawm kev ua tshuaj lom neeg yog muaj peev xwm tswj tau qhov kub thiab txias heev, txij li ntau cov tshuaj tiv thaiv yog qhov kub thiab txias. Txawm tias me ntsis kev hloov pauv hauv qhov kub thiab txias (± 1 degree) tuaj yeem hloov kho tus nqi ntawm cov tshuaj tiv thaiv, ua rau cov khoom tsis zoo, lossis txawm pib muaj teeb meem tshwm sim (xws li tawg lossis hluav taws). High-cov khoom siv hluav taws xob ceev ceev ua kom kub ruaj khov vim tias lawv muaj lub zog ceev ceev thiab cov txheej txheem tswj qhov kub thiab txias. Lawv hnov ​​​​mob sai sai rau cov kev hloov pauv hauv qhov kub thiab txias, uas cia cov neeg ua haujlwm hloov pauv cov ntsuas hauv lub sijhawm kom paub tseeb tias cov tshuaj tiv thaiv muaj kev nyab xeeb thiab ua haujlwm zoo.

Kev nyab xeeb yog qhov tseem ceeb tshaj plaws hauv kev ua tshuaj lom neeg, thiab siab - cov tshuab cua kub ceev ceev muab ntau yam kev nyab xeeb los txo qhov kev pheej hmoo. Lub kaw lus kaw cia cov ntaub ntawv corrosive los ntawm kev nkag mus rau hauv lub tshuab cua sov thiab ua kom puas cov khoom sab hauv (cov hlau tsis kam thiab MgO rwb thaiv tsev), uas tuaj yeem tsim luv luv Circuit Court. High-purity MgO rwb thaiv tsev ua kom hluav taws xob muaj kev nyab xeeb los ntawm kev tso tseg tam sim no thiab hluav taws xob shocks. Tsis tas li ntawd, ntau lub siab- qhov kub thiab txias cartridge tso cua sov muaj cov thermocouples uas ua kom lub qhov muag ntawm lub rhaub dej kub thiab tua nws yog tias nws mus dhau qhov kev nyab xeeb.

Kev ziab qhuav yog lwm yam uas yuav tsum xav txog thaum nws los txog kev nyab xeeb. Hauv kev ua tshuaj lom neeg, cov cua sov feem ntau yog siv rau hauv cov kua dej, thiab khiav lub rhaub tsis muaj immersion (kub qhuav) tuaj yeem ua rau nws overheat, uas tuaj yeem ua rau lub plhaub puas, paug qhov nruab nrab, lossis txawm tias pib hluav taws. High- cov khoom siv hluav taws xob ceev ceev yog tsim los ua kom tag nrho submerged, thiab ntau yam muaj qib sensors uas tua lub rhaub yog tias cov kua qib qis dhau los kom tsis txhob qhuav hlawv.

High-cov khoom siv hluav taws xob ceev uas siv rau hauv kev ua tshuaj lom neeg kuj yuav tsum tau saib xyuas. Cov tshuaj corrosive tuaj yeem tsim cov khoom tso rau ntawm lub rhaub dej kub uas ua haujlwm ua cov insulators, ntxiab cua sov thiab ua rau lub rhaub dej kub. Kev siv cov tshuaj ntxuav tes uas ua haujlwm nrog cov ntaub qhwv los ntxuav nws tsis tu ncua yuav tshem tawm cov deposits thiab xyuas kom meej tias cov cua sov hloov mus zoo. Nws tseem yog ib qho tseem ceeb heev uas yuav tau xyuas cov ntaub qhwv feem ntau rau cov tsos mob ntawm xeb, xws li pitting, discoloration, los yog leaks. Yog tias koj pom muaj, koj yuav tsum hloov lub rhaub.

Hluav taws xob cua sov thiab boilers tsis txhais hais tias yuav tsum tau submerged nyob rau hauv cov ntaub ntawv corrosive, thiab lawv yog loj thiab nyuaj rau haum rau cov khoom siv tshuaj. High-cov khoom siv hluav taws xob ceev ceev, ntawm qhov tod tes, yog me me thiab tuaj yeem hloov kho. Lawv tuaj yeem ua kom haum rau hauv cov tso tsheb hlau luam me me, reactors, lossis cov kav dej kom lawv sov tsuas yog cov cheeb tsam uas xav tau ntau tshaj plaws. Lawv kuj tsis siv ntau thaj chaw los txhim kho, uas ua rau lawv zoo meej rau cov nroj tsuag tshuaj uas twb muaj lawm.

Nyob rau hauv luv luv, siab - ceev cartridge tso cua sov yog qhov zoo tshaj plaws rau cua sov tshuaj vim hais tias lawv muaj kev nyab xeeb, tiv thaiv corrosion, thiab cia koj teem lub kub raws nraim. Nws tseem yog ib qho tseem ceeb uas yuav tau xaiv cov ntaub ntawv sheath kom raug (316L stainless hlau, Incoloy, lossis Hastelloy) kom nws tuaj yeem ua rau muaj kev kub ntxhov. Koj tuaj yeem ua kom paub tseeb tias koj lub siab- lub tshuab cua kub ceev ua haujlwm zoo thiab ntseeg tau los ntawm kev xaiv ib qho nrog cov qauv tsim nyog, ua haujlwm tsis tu ncua, thiab ua raws li kev nyab xeeb zoo tshaj plaws. Qhov no yuav txo qis lub sijhawm poob thiab nce kev ua haujlwm hauv kev siv tshuaj lom neeg.
