Dab tsi ua rau xau hauv lub plhaub thiab lub raj cua kub exchangers?

Qhov ua rau cov dej xau hauv aplhaub thiab raj kub exchangertuaj yeem muab faib ua ob pawg:

tsim teeb meem nrog cov hlab ntsha, thiab kev siv tsis raug ntawm cov khoom siv hluav taws xob los ntawm tus neeg teb xov tooj.

Tsim kom tsis txhob xau yog ib qho kev txiav txim siab ntawm kev tsim zoo ntawm lub plhaub thiab lub raj cua kub exchangers.

Feem ntau ntawm cov xwm txheej (99% +), cov khoom siv hluav taws xob sib txuas yog seamless nrog cov ntawv raj. Lawv tsis yog welded tab sis yog ua los ntawm ib qho. Qhov no zoo heev txo txoj hauv kev ntawm kev xau.

Txawm li cas los xij, cov khoom siv hluav taws xob sib txawv yog qee zaum tsim nrog cov ntaub ntawv lossis cov txheej txheem tsis tsim nyog rau daim ntawv thov, feem ntau, txo cov peev nyiaj. Qhov no yog thaum muaj teeb meem.

Nov yog qee qhov piv txwv.

• Nyob rau hauv lub tshav kub exchanger raug thermal stresses los yog corrosion, seamless los yog welded hlab yuav ua tsis tau tejyam. Nco ntsoov tias feem pua ​​​​ntawm cov welded raj uas ua tsis tiav yog qhov loj dua.
• Nyob rau hauv lub tshav kub exchanger tuav high -kub kua (xws li chav superheater), cov hlab yuav tsuas yog hlawv mus rau qhov chaw ntawm kev puas tsuaj mus tas li.
• Thaum lub tshav kub exchanger tuav cov tshuaj chloride thiab dej, qhov kub thiab txias ua rau cov dej kub npau npau, tawm hauv cov chloride ntau dua li dej. Qhov no corrodes cov kav dej thiab ua rau cov dej xau. Tsis tas li ntawd, thaum cov khoom siv los tsim cov khoom siv hluav taws xob muaj cov kev ntxhov siab uas tshwm sim thaum lub sij hawm tsim khoom (U khoov hlab), kev ntxhov siab corrosion yuav tshwm sim.
• Thaum kawg, cia peb xav txog tsis yog qhov kub siab xwb, tab sis qhov kub siab faib thoob plaws hauv cov ntawv raj. Thaum ib sab ntawm daim ntawv raj yog qhov kub thiab txias heev ntawm lwm qhov, tag nrho cov ntawv raj warps. Qhov no ua rau tuag taus rau kev ua haujlwm ntawm cov gaskets.

Nyob rau hauv txhua rooj plaub, qhov tshwm sim yog sib tov ntawm cov khoom kub thiab txias.

Cov zaj lus qhia yog ib txwm tsim lub tshav kub exchanger nrog cov ntaub ntawv raug rau daim ntawv thov, thiab tsim nws nrog niaj hnub, high quality manufacturing techniques.

Thaum tshav kub kub exchangers feem ntau dhau -tsim. Lawv yuav tsum ua haujlwm tom qab siv ntau xyoo thiab nyob rau hauv ib puag ncig uas ua rau fouling rau cov hlab ntsha. Yog tias xav tau lub tshuab hluav taws xob sib hloov hauv cov roj refinery uas tsim tau 1,000 barrels roj ib feeb, lub tshav kub exchanger yuav zoo li tsim los lis txog 1,500 barrels.

Kev tsim cov khoom siv hluav taws xob ua kom sov li no yog qhov zoo rau kev ua neej ntev thiab kev ntseeg siab, tab sis yuav ua li cas tshwm sim thaum cov roj refinery xav tsim 50% roj ntxiv? Lawv tuaj yeem thawb lub kaw lus mus rau nws qhov txwv. Lub tshav kub exchanger tuaj yeem tuav nws, tab sis ntawm tus nqi. Cov kua dej yuav dhau los ntawm tib tus ntoo khaub lig- ntu ntawm qhov nrawm dua, thiab thaum lub nrawm nce mus, kev vibrations tshwm sim. Tom qab ntawd koj tau erosion ntawm nozzles.

Kev thawb lub tshuab hluav taws xob dhau los ntawm nws cov qauv tsim yuav ua rau cov khoom siv sai dua, ua rau cov dej xau thiab tsis ua haujlwm.

Thaum tshav kub kub exchanger leaks tuaj yeem zam los ntawm kev ua raws li lawv cov qauv tsim. Yog tias koj xav hloov pauv kev ua haujlwm ntawm cov khoom siv hluav taws xob, koj yuav tsum tham nrog koj lub chaw tsim hluav taws xob hloov hluav taws xob rau cov lus qhia, yog li qhov cuam tshuam ntawm kev hloov pauv tuaj yeem tshawb xyuas.

Ua haujlwm nrog cov chaw tsim khoom ntseeg siab uas yuav siv cov qauv tsim thiab cov ntaub ntawv tsim nyog. Ntawm GNEE, peb muaj ntau tshaj 100 xyoo ntawm kev paub nyob rau hauv lub tshav kub exchanger tsim, thiab ib txwm muab kev sib raug zoo nrog peb cov neeg muas zaub ua ntej. Xav paub ntau ntxiv ntawm nplooj ntawv no: Vim li cas koom tes nrog peb?

Cov kauj ruam hauv qab no yuav tsum tau ua nrog koj tus engineers sab hauv lossis nrog kev pab los ntawm koj lub chaw tsim khoom.

Thawj qhov yog los tshuaj xyuas qhov xau. Saib seb muaj pes tsawg lub raj xau thiab qhov hnyav ntawm cov xau.

Txhawm rau kho qhov xau, muaj ob peb txoj kev xaiv.

Tej zaum koj tuaj yeem ntsaws cov raj ua rau qhov teeb meem. Vim hais tias lub plhaub raj kub exchangers yog overdesigned, yog tias koj tsuas muaj ib feem me me ntawm cov hlab xau (tsawg dua 5%, piv txwv li), thiab koj thaiv lawv, lub exchanger tseem yuav ua tau raws li nws cov dej num.

Vim yog fouling yam, qee qhov hluav taws kub exchangers yog 50% loj tshaj qhov xav tau. Yog li ob peb feem pua ​​​​ntawm no thiab tsis muaj kev cuam tshuam rau kev ua haujlwm.

Es tsis txhob ntsaws cov raj, re-tubing tej zaum yuav yog qhov kev xaiv. Qhov no siv tau thaum cov raj tsis welded rau lub raj ntawv. Cov teeb meem cov raj raug tshem tawm, hloov pauv, thiab cov khoom siv hluav taws xob tuaj yeem ua haujlwm zoo li qub.

Nyob rau hauv cov ntaub ntawv uas lub raj ntawv yog warped, nws yuav ua tau kom tshuab ua hauj lwm nws rov qab mus rau usable mob. Hauv cov xwm txheej hnyav dua, tag nrho cov ntawv raj yuav tsum tau hloov, txawm tias qhov no yog ib qho kev daws teeb meem kim.

Feem ntau, kev kho ntau yam txhais tau tias xa cov khoom siv hluav taws xob rov qab mus rau cov chaw tsim khoom, txawm tias qee zaus cov haujlwm tuaj yeem ua tiav ntawm - qhov chaw.

Hu rau tam sim no

Xav tau cov kev qhia tshwj xeeb, cov ntaub ntawv pov thawj kev ua haujlwm, thiab cov lus hais rau cov khoom siv hluav taws xob? Xa cov lus nug lossis txuas nrog peb ncaj qha, thiab peb yuav ua kom muaj txiaj ntsig zoo rau kev daws teeb meem tshwj xeeb.
