Thaiv tsis ua hauj lwm ntawm titanium cua sov raj yog hais txog mus tas li tso tseg ntawm tshem tawm impurities, crystalline precipitates, corrosion khoom thiab teev nyob rau hauv lub raj, uas nqaim los yog kiag li thaiv qhov ntws hla -section. Kev khiav dej num ntawm lub cev poob qis qis, kev siv hluav taws xob pauv hluav taws xob poob qis, thiab cov ntu thaiv kev raug kev txom nyem hauv zos cov cua sov thiab overheating. Kev sib txawv ntau dhau ua ntej thiab tom qab kev txhaws ua rau muaj qhov txawv txav ntawm cov raj xa dej, weld cracking thiab cov yeeb nkab phab ntsa rupture nyob rau hauv overpressure. Qhov kev ua txhaum no dav muaj nyob rau hauv lub tshuab cua sov uas tsis muaj qhov nruab nrab pom thiab kev tu tsis tu ncua, uas yog cov dej ntws tsis ua haujlwm tshwm sim los ntawm cov khoom hauv cov khib nyiab.
1. Blockage Generation thiab Failure Evolution Mechanism
Cov khoom raug tshem tawm thiab yooj yim -crystallization ntsev nyob rau hauv nruab nrab nyob rau hauv cov phab ntsa sab hauv thaum lub khiav ceev tsis txaus. Nyob rau hauv tas li cua sov, soluble ions precipitate mus rau hauv crystalline scale thiab adhere khov kho rau lub raj phab ntsa. Qhov zoo sab hauv txoj kab uas hla shrinks xyoo los ntawm lub xyoo, pipeline flow resistance nce thiab twj tso kua mis siab nce. Ib nrab blockage tsim cov dej tuag qhov chaw uas cov sediments accumulates sai heev thiab ua kom tiav plugging. Kev ncig nruab nrab yog hindered, tshav kub tsis tuaj yeem raug xa tawm raws sijhawm, ua rau lub zos overtemperature thiab thermal stress concentration. Lub caij no, qhov chaw nyob hauv cov blockages nrawm nrawm thiab nyob rau hauv - tso tawm corrosion ntawm titanium substrate, nws thiaj li ua rau los ntawm - phab ntsa perforation los yog siab tawg ntawm lub cua sov raj. Tsis zoo li ib qho kev puas tsuaj, kev thaiv yog qhov ua tsis tiav uas tshwm sim los ntawm qhov ntev - lub sij hawm maj mam sib sau ua ke ntawm txawv teb chaws.
2. Tej yam hauj lwm uas muaj kev cuam tshuam
Lub luj tshib, tees thiab reducers nrog ntws kev taw qhia hloov qhov twg impurities yog nquag mus deposition;
Hauv qab ntawm cov kav dej kab rov tav nrog cov dej ntws tsis muaj zog thiab lub sijhawm ntev - cov av nkos;
Cov kav dej tuag ceg thiab ceg kav dej nrog ultra- ntws qis lossis ua haujlwm tsis sib xws;
Cua sov tube inlets thiab me - txoj kab uas hla coil seem nrog nqaim ntws;
Cov kua dej hloov pauv cov cheeb tsam uas nruab nrab evaporation ua rau ntsev ntxiv thiab crystallization scaling.
3. Cov ntsiab lus tseem ceeb ua kom ceev cov kav dej thaiv
Tsis muaj pem hauv ntej-kawg pom cov cuab yeej, tso cai rau cov khoom loj heev nkag mus rau hauv lub voj voog ncig;
Ntev-lub sij hawm qis- khiav lag luam tsis ua kom muaj kev kub ntxhov rau kev sib tsoo phab ntsa;
High hardness thiab siab ion concentration ntawm circulating nruab nrab ua rau yooj yim cua sov crystallization;
Tsis muaj tshuaj tu ncua sij hawm thiab dej hauv online, ua rau muaj kev nce qib ntawm cov nplai;
Kev tsim cov kav dej tsis tsim nyog nrog kev khoov ntau dhau, txo txoj kab nruab nrab sai sai thiab rov ua dua cov dej tuag.
4. Tag nrho -Txuas Kev Tiv Thaiv thiab Tswj Kev Ntsuas Kev Ntsuas
① Nruab ntau-theem precision pom thiab slag ntxiab cuab yeej ntawm qhov system inlet
Intercept particle pollutants fundamentally txiav tawm qhov chaw ntawm blockage.
② Txhim kho cov kav dej kom zoo kom txo tau cov kev hloov pauv sai sai thiab tshem tawm cov kav dej dig muag
Txo cov luj tshib uas tsis tsim nyog thiab cov seem shrinkage tam sim ntawd kom tsis txhob muaj cov cheeb tsam nyob ruaj khov.
③ Tswj kom ceev nrawm nrawm nrawm hauv cov txheej txheem tso cai
Siv cov dej scouring los tswj cov particle adhesion thiab sediment deposition ntawm sab hauv phab ntsa.
④ Tsim kho - voj voog hauv online flushing thiab pickling descaling cov phiaj xwm
Tsis tu ncua tshem tawm nplai thiab sediments los kho qhov qub ntws ntawm cov kav dej.
⑤ Ntxiv scale inhibitors thiab dispersants rau circulating nruab nrab
Tshem tawm ion crystallization thiab nplai adhesion los ntawm cov kua dej system.

| System Configuration & Maintenance Mode | Blockage Risk | Daim ntawv thov tswv yim |
|---|---|---|
| Tsis pom + ntev - lub sij hawm qis ntws + tsis tu ncua | Ib nrab los yog tag nrho cov blockage tshwm sim sai thaum lub sijhawm ua haujlwm | Ntxiv cov cuab yeej lim thiab siv cov kav dej tso dej tawm tam sim |
| Pem hauv ntej- kawg impurity cuam tshuam + tus qauv ntws tus nqi + ncua sij hawm descaling | Ua tau zoo tiv thaiv cov raj xa dej loj clogging | Standard configuration rau cov pa titanium cua sov ncig systems |
| Medium dosing anti-scaling + flow field optimization + differential siab tiag tiag -lub sij hawm saib xyuas | Tsis tshua muaj blockage probability | Cov txheej txheem nyiam rau kev tsis cuam tshuam ntev - cov khoom siv ntau lawm |
Xaus
Thaiv tsis ua hauj lwm ntawm titanium cua sov raj pib los ntawm sediment deposition, ntsev crystallization thiab scale adhesion nyob rau hauv lub pipeline, uas txo qhov chaw ntws thiab induces txawv txav siab thiab lub zos overheating. Cov tswv yim tiv thaiv tseem ceeb suav nrog cuam tshuam cov impurities sab nraud ntawm qhov chaw, txhim kho txoj hauv kev zoo kom txo tau cov txheej txheem kev tso nyiaj, tswj xyuas kom zoo scouring txaus ceev thiab tsis tu ncua tshem tawm cov av. Kaw-Txoj kev tswj lub voj voog uas npog qhov nruab nrab purification, kev tsim cov raj xa dej thiab kev saib xyuas txhua hnub tuaj yeem zam kom tsis txhob muaj cov khoom kaw thiab kev nyab xeeb raug xwm txheej tshwm sim los ntawm cov cua sov raj thaiv.
