Hauv kev lag luam chemical, purity ntawm cov kua hauv cov kav dej ncaj qha cuam tshuam rau cov khoom zoo, cov khoom siv lifespan thiab kev ruaj ntseg ntau lawm.Filtration precisionyog qhov tseem ceeb tshaj plaws technical parameter ntawm achemical pipeline lim, uas txiav txim siab lub peev xwm los cuam tshuam cov khoom impurities hauv cov kua tshuaj thiab yog lub hauv paus tseem ceeb rau B- kawg cov neeg yuav khoom xaivindustrial lim rau kev lag luam tshuaj. Tsab ntawv xov xwm no yuav piav qhia txog lub ntsiab lus ntawm kev pom tseeb, nws cov qauv ntsuas, thiab kev siv tau zoo hauv cov raj xa dej lim dej, pab cov nroj tsuag tshuaj, pab pawg engineering thiab cov neeg tswj xyuas kev yuav khoom ua cov ntaub ntawv -tsav lim kev txiav txim siab.
Dab tsi yog filtration precision nyob rau hauv cov tshuaj pipeline lim?
Filtration precision hais txog qhovYam tsawg kawg nkaus qhov loj me ntawm impurities uas lub raj xa dej lim tuaj yeem cuam tshuam zoo, feem ntau ntsuas hauvmicrons (μm)-tseem hu ualim micron ntsuasnyob rau hauv industrial terminology. Nws tsis yog ib qho yooj yim daim ntawv lo ntawm lim lub pore loj, tab sis ib qho kev qhia qhia txog qhov tseeb interception efficiency ntawm lub lim nruab nrab nyob rau hauv tej yam tshuaj ua hauj lwm tej yam kev mob (xws li kub siab, corrosive kua). Piv txwv li, 20μm chemical pipeline lim txhais tau hais tias nws tuaj yeem ntes ntau dua 95% ntawm cov khoom siv nrog lub cheeb ntawm 20μm thiab siab dua hauv cov kua dej (qhov tshwj xeeb cuam tshuam nrogISO 16889 Kev Tswj Xyuas Kev Lag Luamcov qauv rau kua lim media).
Hauv kev tsim tshuaj, impurities xws li pipeline xeb, catalyst residues thiab raw khoom precipitates feem ntau ntawm 1μm mus rau 1000μm. Cov txheej txheem tshuaj sib txawv-xws li kev siv tshuaj raw khoom purification, petrochemical kev thauj mus los thiab tshuaj tua kab synthesis-yuav tsum tauchemical pipeline limnrog txuam pom precision kom sib npaug purification los thiab ntau lawm efficiency.
Yuav ua li cas filtration precision ntsuas rau chemical pipeline lim?
Chav ntsuas: Micron vs Mesh rau tshuaj lim precision
Lub hauv paus ntsiab lus ntawm kev pom tseeb rau cov tshuaj lim dej lim dej yog micron (μm), thaum mesh (tus naj npawb ntawm qhov pores ib square inch ntawm lub vijtsam lim) yog siv rau qee qhov xwm txheej. Kev hloov pauv yog kwv yees li: 100 mesh ≈ 150μm, 200 mesh ≈ 75μm, 400 mesh ≈ 38μm. Txawm li cas los xij, mesh tsuas yog qhia txog qhov ntom ntawm lub vijtsam lim thiab tsis tuaj yeem sawv cev rau qhov tseeb pom tseeb ntawm cov kua dej tshuaj, yog lilim micron ntsuasyog chav tsev nyiam hauv kev siv tshuaj lom neeg engineering.
Cov qauv ntsuas rau cov tshuaj lim dej precision
Kev pom tseeb ntawm cov kav dej lim dej yuav tsum ua raws li cov qauv kev lag luam thoob ntiaj teb kom ntseeg tau tias muaj kev ntseeg siab:
- TS EN ISO 2942 Cov: Txheeb xyuas qhov kev tsim khoom ncaj ncees ntawmPP / PTFE lim ntsiabthiab kuaj cov npuas taw tes (qhov taw qhia tseem ceeb rau kev ntsuas qhov tsawg kawg nkaus qhov pore loj ntawm lub lim nruab nrab).
- ISO 16889 Kev Tswj Xyuas Kev Lag Luam: Qhia meej txog txoj kev sim rau kev ua kom pom kev ua haujlwm ntawm cov kua lim tawm, kom ntseeg tau qhov tseeb ntawm qhov pom tseeb daim ntawv lo rau cov lim dej lim dej.
Cov kws tshaj lij lim cov tuam txhab lag luam yuav muab cov ntawv tshaj tawm thib peb - tog los ua pov thawj tias lawvchemical pipeline limUa tau raws li cov lus pom tseeb ntawm cov khoom siv hauv cov dej tshuaj (xws li, siab viscosity, muaj zog corrosion).
Cov ntsiab lus tseem ceeb cuam tshuam rau kev pom qhov tseeb ntawm cov tshuaj lim dej lim dej
Qhov tseeb filtration precision ntawm achemical pipeline limtsis kho thiab cuam tshuam los ntawm ntau yam hauv kev tsim tshuaj lom neeg:
Lim cov khoom nruab nrab thiab cov qauv siv tshuaj lom neeg pom
- Khoom siv: Chemical pipelines feem ntau thauj cov kua corrosive (acids, alkalis, organic solvents).PP lim cov ntsiab lusyog tsim rau cov tsis muaj zog acid thiab alkali ib puag ncig nrog kev pom tseeb ntawm 1-100μm;PTFE lim cov ntsiab lustuaj yeem tiv taus corrosion thiab kub siab (tsawg dua lossis sib npaug li 260 degree), nrog rau qhov tseeb ntawm 0.1-50μm, zoo tagnrho rau kev ua haujlwm siabchemical kua filtrationhauv kev tsim tshuaj thiab hluav taws xob chemical.
- Tus qauv tsim: Ib qho - txheej lim cov ntxaij vab tshaus tau kho qhov tseeb tab sis tsis zoo los tiv thaiv-kev ua haujlwm txhaws; multi- txheej txheej lim cov ntsiab lus (pre-filtration layer + fine filtration layer) cuam tshuam cov khoom loj ua ntej thiab tom qab ntawd ntes cov impurities zoo, tswj kom ruaj khov pom tseeb hauv siab - cov kua dej tsis huv.
Cov kua dej tshuaj ua haujlwm
- viscosity: High-cov kua viscosity (cov roj resin, roj) txo cov kev cuam tshuam ntawm cov lim. Piv txwv li, ib tug 10μmchemical pipeline limtsuas tuaj yeem cuam tshuam cov khoom siab tshaj 15μm hauv siab -cov kua tshuaj viscosity.
- Kub: Qhov kub thiab txias ntau dhau ua rau cov khoom siv lim tawm (xws li, PP cov ntxaij lim dej poob siab tshaj 90 degree), thaum qhov kub thiab txias ua rau cov kua viscosity thiab cuam tshuam rau impurity interception.
- Impurity concentration: Yog hais tias cov ntsiab lus impurity nyob rau hauv cov kua tshuaj ntau tshaj 500mg / L, lub lim nto tsim ib lub ncuav mog qab zib lim sai, thaiv qhov hws thiab txo qhov tseeb pom tseeb.
Kev ua haujlwm tsis ua haujlwm ntawm cov lim dej lim dej
- Tus nqi ntws: Cov dej ntws ntau dhau ua rau cov kua dej "scour" cov lim nruab nrab, tso cai rau cov khoom zoo kom dhau mus thiab txo qhov pom tseeb; tsawg dhau tus nqi cuam tshuam ntau lawm efficiency.
- Siab sib txawv: Lub siab sib txawv siab tshaj 0.2MPa ntawm lub lim lub inlet thiab qhov hluav taws xob compresses lub lim nruab nrab, ua rau pore deformation thiab tsis raug pom precision.
Yuav ua li cas xaiv filtration precision rau chemical pipeline lim?
Tshuaj lim precision xaivxav tau kev sib txuas cov txheej txheem tshuaj lom neeg thiab cov khoom siv tiv thaiv kev xav tau, thiab cov kws tshaj lij kev lag luam tuaj yeem muab taukev cai chemical pipeline limcov kev daws teeb meem rau cov xwm txheej tshwj xeeb:
- Cov cuab yeej tiv thaiv- taw qhia: Rau cov khoom siv precision (twj, ntsuas, li qub) hauv cov kav dej tshuaj, xaiv achemical pipeline limnrog rau qhov tseeb ntawm 50-100μm los tiv thaiv cov khoom loj los ntawm kev hnav thiab thaiv cov khoom siv.
- Khoom zoo -oriented: Nyob rau hauv siab -purity tshuaj ntau lawm (pharmaceutical intermediates, hluav taws xob tshuaj), siv lub lim nrog ib tug precision ntawm 1-10μm kom tshem tawm cov kab impurities thiab xyuas kom meej cov khoom purity-kev cai chemical pipeline limtuaj yeem ua raws li ultra-siab precision yuav tsum (tsawg dua lossis sib npaug li 1μm) rau cov txheej txheem tshwj xeeb.
- Sib npaug efficiency thiab nqi: Ultra-siab precision (tsawg dua lossis sib npaug li 1μm) cov ntxaij lim dej muaj cov nqi siab thiab muaj feem cuam tshuam. Ob -theem filtration system (coarse filtration + fine filtration) raug pom zoo rau feem ntau cov kab ntau lawm, uas peb pab neeg tuaj yeem tsim ua ib feem ntawmkev cai chemical pipeline limdaws.
Filtration precision yog qhov tseem ceeb ntawmchemical pipeline lim, ncaj qha ntsig txog kev ruaj ntseg ntawm cov tshuaj lom neeg thiab cov khoom tiav. Rau B- cov neeg siv khoom kawg xws li cov nroj tsuag tshuaj thiab cov tuam txhab engineering, nkag siab txog cov ntsiab lus, kev ntsuas cov qauv thiab cuam tshuam cov txiaj ntsig ntawm kev pom tseeb yog qhov tsim nyog ntawm kev xaiv tsim nyog.industrial lim rau kev lag luam tshuaj.
Raws li cov kws tshaj lij lim chaw tsim khoom, peb muabkev cai chemical pipeline limCov kev pab cuam haum rau koj cov yam ntxwv ntawm cov kua dej (corrosivity, viscosity, kub) thiab cov txheej txheem yuav tsum tau ua. Peb ib qho - nres kev daws teeb meem npog kev xaiv lim,PP / PTFE lim caijcustomization, kev taw qhia kev teeb tsa thiab tom qab- kev muag khoom muag, ua kom pom tseeb ntawm koj cov kav dej lim dej zoo kawg nkaus phim cov kev xav tau tiag tiag.
