Khoom Taw Qhia
Ceramic Membrane Rau Kev Kho Mob Yog Hom Inorganic txiav txim siab los ntawm cov khoom siv hluav taws xob, cov iav muaj zog, thiab cov tshuaj tiv thaiv kub, thiab corrosion tsis kam) thiab applicion Cov xwm txheej {. Cov hauv qab no piv rau qhov sib txawv ntawm ob los ntawm cov qauv tseem ceeb, kev sib txuas qauv, thiab lwm yam}):
Cov txheej txheem raug teeb tsa ntawm silicon carbide ceramic membrane
Lub ntsiab lus tseem ceeb ntawm Silicon Carbide (Sic) Ceramic Membrane muaj zog (BEADE} thiab muaj zog corrosion (xws li tshuaj pleev cov tshuaj pleev roj av, cov tshuaj yej siab roj pleev, thiab lwm yam} .
# {1. Cov qauv tsim qauv
- Cov tub ntxhais tseem ceeb yog ntau-channel membrane raj (feem ntau 19}} lub raj mis yog {} mu} mm.
- Cov khoom sib xyaw yog ib qho kev sib xyaw ntawm "membrane plhaub": ntau qhov kev ntsuas siab tawv nqaij), thiab cov kev ntsuas siab
# {2. sealing txoj kev
Vim tias qhov yuav tsum tau tiv thaiv kom muaj qhov kub siab (> 200 degree) thiab muaj zog corrosion, dog dig roj hmab ntsaws ruaj ruaj, thiab cov ntaub ntawv sealing hauv qab no siv:
- Cov Ntsia Hlau Hlau: xws li cov hlau taub hau hlau, tooj liab / Nickel alloy gaskets, uas yog tsim nyog rau cov pa taws kub ua ntej 300 degree.
- Ceramic Foob: Siv cov pa roj ceramic xws li mullite thiab corundum, haum nrog ultra-siab qhov kub tshaj plaws 500 degree.
- Sealing txoj hauj lwm: qhov kev sib tshuam ntawm cov kev cuam tshuam nruab nrab ntawm ob xaus ntawm daim nyias nyias nyias thiab daim nyias nyias yuav tsum tswj hwm (yuam kev<0.1mm/m) to avoid mechanical stress causing membrane tube rupture.
# {3. txoj kev sib txuas
- feem ntau yog flange kev txuas: Ob xaus ntawm daim nyias nyias uas siv cov pa taws kub thiab zom zaws ntawm cov pa hluav taws kub thiab zom zaws kom tsis muaj xau dej siab.
- Kev qhib Flange Quicks (nrog clamps) tuaj yeem siv hauv cov khoom tshwj xeeb (xws li cov khoom siv txawb), tab sis cov qauv ua kom nruj ntawm cov qauv hlau khi yuav tsum tau ntxiv.
# {4.} Nruab Nruab Nruab Nrab
- Lub raj mis mos yuav tsum tau muab ntsia cov kab ntsug lossis kab rov tav (qaij ib qho tsawg dua lossis sib npaug ntawm 5 degree) kom tsis txhob muaj kev ntxhov siab tsis sib xws los ntawm kev sib tsoo ntawm lub ntiajteb txawj nqus.
- Ua ntej kev teeb tsa, daim ntawv membrane raj channel xav tau ntxuav nrog huab cua compressed kom tshem tawm impurities; Tom qab kev teeb tsa kev teeb tsa yog qhov yuav tsum tau (1 {{}}}} 2 zaug ua haujlwm siab, lub siab khaws cia rau 30 feeb yam tsis muaj xau).
Cov txheej txheem kev teeb tsa ntawm lwm cov kev ua kom huv (noj alumina thiab zirconia cov tshuaj tsw qab ua piv txwv)
Cov neeg kho tshuab zog (khoov zog {{}} mpa mpa kom muaj zog dua li ntawm cov kua nqaij uas tsis tshua muaj zog dua li ntawm cov kua qaub thiab qhov ntev tshaj plaws corrosion tej yam kev mob (xws li khoom noj khoom haus kom tsis muaj menyuam, haus cov dej huv, thiab tshuaj siv tshuaj).
# {1. Cov qauv tsim qauv
- Daim nyias nyias nyias yog feem ntau yog ib feem ntau cov channel lossis ntau cov channel ({} m thiab ib qhov ntev ntawm {} mm (sib dua).
- Lub plhaub memb yog ua los ntawm cov steel stainless hlau, qib siab (qis dua tus nqi), thiab lub siab ua haujlwm feem ntau yog tsawg dua los yog sib npaug rau 1. 0mpa.
# {2. sealing txoj kev
Vim yog cov haujlwm ua haujlwm me me (kub<150℃, weak corrosion), rubber seal is mainly used: - Sealing materials: nitrile rubber (oil resistant), fluororubber (medium corrosion resistant), made into O-rings or lip seals.
- Daim Ntawv Sealing: cov roj hmab nplhaib tau compressed los ntawm cov kauj ruam txheej txheem ntawm ob qho tib si ntawm daim tawv nqaij ", thiab lub teeb meem siab (tsis muaj siab dua).
# {3. txoj kev sib txuas
- Feem ntau clamp lub plhaub txuas nrog lub raj xa hluav taws xob nrog cov raj xa tawm sai sai, uas yooj yim rau kev tu cev nqaij daim tawv (yooj yim rau kev tu cev nqaij daim tawv) {}
- Threaded kev twb kev txuas tuaj yeem siv rau hauv cov xwm txheej tsis tshua muaj siab (<0.3MPa), and raw tape can be used to enhance sealing.
# {4.} Nruab Nruab Nruab Nrab
- Nws yog qhov tsim nyog kom tsis txhob muaj kev sib tsoo ntawm membrane hlab (tawg yooj yim), thiab cov gaskets yuav tsum tau siv rau buffering thaum lub sij hawm installation thaum installation thaum installation {}}
- cov roj hmab ntsaws ruaj ruaj yuav tsum sib cuag nrog cov kuab tshuaj organic (xws li dej cawv thiab acetone) los tiv thaiv o thiab tsis ua hauj lwm}
