Phaj kub exchanger nyob rau hauv lub lag luam ntawm kev siv lub sij hawm tej zaum yuav tshwm sim teeb meem corrosion, ces, koj puas to taub vim li cas tom qab no tshwm sim? Hauv qab no los ntawm kuv rau koj los piav qhia luv luv txog qee qhov laj thawj tseem ceeb rau qhov xwm txheej no.
Phaj tshav kub exchanger corrosion ntawm lub ntsiab yog vim li cas:
1. Vim tias cov hlau stainless hlau hloov hluav taws xob phaj yog ua tiav los ntawm cov khoom siv hlau stamping, yog li nws yuav tawm ntawm qee qhov kev ntxhov siab rau ntawm lub phaj nto. Tshwj xeeb tshaj yog rau cov ntawv hlau stainless uas tsis muaj molybdenum, nws yog qhov nyuaj heev los tshem tawm cov kev ntxhov siab uas seem, thiab tej zaum yuav ua tsis tau.
2. Lub phaj kub exchanger yog tsim los ntawm kev sib xyaw ua ke ntawm ntau daim hlau, thiab ntau qhov sib txawv yuav raug tsim los ntawm cov phaj, xws li cov ntsiab lus sib txuas ntawm cov phaj thiab hauv qab ntawm lub sealing zawj thiab lwm qhov chaw. Cov khoob no tuaj yeem yooj yim ua rau muaj cov tshuaj chloride ions (Cl-), qhov concentration uas feem ntau nyob deb tshaj qhov kev ntxhov siab corrosion ntawm cov khoom siv hlau stainless nws tus kheej.
3. Yog tias muaj ntau cov av accumulates nyob rau saum npoo ntawm lub phaj, ces cov khoom corrosive nyob rau hauv nruab nrab, xws li chlorine (Cl), sulfur (S), thiab lwm yam, tej zaum yuav adhering rau cov av nyob rau hauv ntau qhov ntau thiab ntxiv enrichment. hauv cov crevices.
4. Nyob rau hauv qab ntawm lub sealing zawj tej zaum yuav muaj teeb meem, uas feem ntau yog chlorine Cheebtsam ntawm lub binder uas precipitate ntawm siab kub. Piv txwv li, nrog tsev neeg neoprene ntawm kev sib txuas cov neeg ua hauj lwm thiab compressed asbestos uas muaj calcium chloride (CaCl2), precipitated chloride ions ua ke nrog hydrogen ions los ua hydrochloric acid (HCl) nyob rau hauv dej vapor tej yam kev mob, ua rau muaj kev nyuaj siab corrosion tawg nyob rau hauv lub qab ntawm cov dej. cov groove seams.
Nyob rau hauv kev teb rau saum toj no lub ntsiab ua rau lub phaj kub exchanger corrosion, peb muaj peev xwm ua raws li nram no kev tiv thaiv thiab txij nkawm ntsuas kom ntev lub neej kev pab cuam ntawm cov cuab yeej thiab xyuas kom meej nws ib txwm ua hauj lwm:
1. Kev xaiv cov khoom siv
- Xaiv cov khoom siv stainless hlau uas muaj cov ntsiab lus molybdenum los txhim kho kev tiv thaiv kev ntxhov siab.
- Xav txog kev siv cov ntaub ntawv alloy nrog zoo corrosion kuj, xws li titanium alloy lossis npib tsib xee alloy.
2. Kev kho deg:
- Thaum tshav kub kub kho los yog nto kho daim hlau thiab cov nplooj ntawv kom txo lossis tshem tawm cov kev ntxhov siab uas seem.
- Siv cov txheej txheem txheej txheej txheej xws li plating lossis anodizing los muab cov txheej txheem tiv thaiv ntxiv.
3. Kev tsim kho kom zoo:
- Txhim kho daim ntawv tsim kom zoo kom txo tau qhov khoob thiab qhov chaw tuag kom txo tau cov tshuaj chloride ion enrichment.
- Kev siv cov khoom siv sib khi thiab cov qauv zoo tshaj plaws los txo cov nag lossis daus ntawm cov khoom tsis zoo.
4. Kev tu thiab tu:
- Ntxuav lub phaj kub exchanger tsis tu ncua kom tshem tawm cov khoom txuam ntawm cov av thiab corrosion.
- Siv cov tshuaj ntxuav tes los yog lub dav hlau dej siab rau kev ntxuav, tab sis nco ntsoov tias cov tshuaj ntxuav siv tsis ua rau cov ntaub ntawv phaj puas.
5. Kev Kho Media:
- Kho qhov nruab nrab ua haujlwm, xws li dechlorinating lossis softening, kom txo cov ntsiab lus ntawm cov khoom corrosive.
- Tswj pH ntawm nruab nrab kom tsis txhob muaj acidic lossis alkaline ib puag ncig thiab txo qhov yuav tshwm sim ntawm corrosion.
6. Kev kuaj xyuas thiab saib xyuas:
- Tsis tu ncua tshuaj xyuas phaj kub exchangers rau corrosion, siv txoj kev xws li ultrasonic, eddy tam sim no los yog pom kev soj ntsuam.
- Saib xyuas cov tshuaj muaj pes tsawg leeg ntawm qhov nruab nrab thiab kev ua haujlwm xws li kub, siab thiab ntws tus nqi los kwv yees thiab tiv thaiv corrosion.
7. Cov txheej txheem ua haujlwm:
- Qhia cov neeg ua haujlwm kom paub tseeb tias lawv nkag siab txog qhov ua rau corrosion thiab tiv thaiv kev ntsuas.
- Tsim thiab siv cov txheej txheem ua haujlwm kom raug, suav nrog kev pib ua haujlwm, kaw, thiab ntxuav cov txheej txheem.
Los ntawm kev siv cov kev tiv thaiv thiab kev saib xyuas, koj tuaj yeem txo qhov kev pheej hmoo ntawm corrosion hauv phaj kub exchangers, xyuas kom meej tias lawv ua haujlwm ruaj khov mus ntev, thiab txo cov nqi kho thiab hloov cov nqi.
