Kev ntxuav ntawm finned heat exchangers thiab lwm yam khoom siv tau dhau los ua qhov tseem ceeb thiab tseem ceeb txuas hauv kev tsim khoom, tshwj xeeb tshaj yog nyob rau hauv petrochemical thiab thermal fais fab nroj tsuag.Dab tsi yog vim li cas thiab cov txheej txheem ua haujlwm tseem ceeb rau finned heat exchanger tu?Cia kuv piav qhia rau koj.
Nyob rau hauv cov txheej txheem ntawm kev tsim tshuaj ntxuav kev lag luam, rau ntau yam, ntau coking, roj av, nplai, sediment, corrosion khoom, polymer, fungi, thiab lwm yam yuav tsim nyob rau hauv lub fin heat exchanger khoom thiab pipeline kab,such li algae thiab slime.Cov av uas tshwm sim yuav ua rau cov khoom siv thiab cov kav dej ua tsis tiav, thiab cov khoom siv hluav taws xob yuav txo qis, thiab kev siv hluav taws xob thiab cov khoom siv yuav nce ntxiv.Kev poob nyiaj txiag, txawm tias tsim kev puas tsuaj loj tuaj yeem tshwm sim.
Feem ntau muaj ob txoj hauv kev ntawm kev lag luam tu ntawm finned tshav kub exchanger tu: tshuaj ntxuav thiab high-pressure dej dav hlau tu.Tab sis rau lub sijhawm ntev, cov txheej txheem kev tu ib txwm siv thiab kev kho mob, xws li cov txheej txheem siv tshuab, dej siab, tshuaj ntxuav (pickling), nplai inhibition, thiab lwm yam, tsis tuaj yeem daws qhov teeb meem zoo thiab tuaj yeem ua rau muaj kev puas tsuaj loj rau cov cuab yeej nws tus kheej, tib neeg lub cev thiab ib puag ncig.Nrog rau txoj kev loj hlob sai ntawm kev lag luam niaj hnub, kev siv dej txias tsis yog tsuas yog nce, tab sis kuj tseem muaj cov nplai uas twb muaj lawm hauv cov khoom siv sib hloov pauv loj tsis tuaj yeem raug tshawb fawb, uas ua rau kev siv hluav taws xob thiab kev puas tsuaj ib puag ncig, thiab txo kev ua haujlwm.Nyob rau hauv cov txheej txheem ntawm kev tsim tshuaj ntxuav kev lag luam, rau ntau yam, ntau coking, roj av, nplai, sediment, corrosion khoom, polymer, fungi, thiab lwm yam yuav tsim nyob rau hauv lub fin heat exchanger khoom thiab pipeline kab,xws li algae thiab slime.Cov av uas tshwm sim yuav ua rau cov khoom siv thiab cov kav dej ua tsis tiav, thiab cov khoom siv hluav taws xob yuav txo qis, thiab kev siv hluav taws xob thiab cov khoom siv yuav nce ntxiv.Kev poob nyiaj txiag, txawm tias tsim kev puas tsuaj loj tuaj yeem tshwm sim.
Cov txheej txheem ua haujlwm tseem ceeb tshaj plaws rau fin heat exchanger tu yog:
- Descaling thiab tu.Ntxiv kev npaj descaling thiab tu tus neeg sawv cev hauv kev faib ua feem rau cov dej ntws hauv lub tank rau kev ntxuav boiler thiab descaling.Txiav txim siab tus nqi ntawm cov tshuaj raws li lub sij hawm tu lub voj voog thiab tus nqi teev.Tom qab ua kom paub tseeb tias tag nrho cov nplai raug ntxuav, mus rau txoj kev ntxuav tom ntej.
- Yaug nrog dej huv.Tom qab txuas cov khoom siv tu rau lub boiler, ntxuav nws nrog dej huv rau 10 feeb, xyuas qhov xwm txheej ntawm lub cev, xyuas seb puas muaj cov dej xau, thiab ntxuav cov nplais ntab rau tib lub sijhawm.
- Strip anti-corrosion ntxuav.Ntxiv tus neeg sawv cev stripping nto thiab qeeb-tso tus neeg saib xyuas nyob rau hauv kev faib ua feem rau cov dej ntws ntawm lub tank tu thiab ua kev tu rau 20 feeb kom cais cov nplai ntawm cov khoom ntxuav.
- Passive txheej kho.Ntxiv passivation txheej tus neeg sawv cev los ua passivation txheej kev kho mob nyob rau hauv boiler tu system los tiv thaiv corrosion thiab tshiab xeb tsim ntawm pipelines thiab cov khoom.
