Yuav ua li cas xaiv ib qho haum hydrogen peroxide chaw thau khoom
Qhov tseem ceeb kev txiav txim siab los xaiv qauv
1. Cov khoom nruab nrab thiab kev ua haujlwm
Hydrogen peroxide concentration:
30% concentration: Feem ntau xaiv 304 stainless hlau (SS304) rau kev tiv thaiv corrosion.
High concentrations (>50%): Pom zoo 316L stainless hlau rau kev txhim kho kom ua kom oxidative corrosion.
Qhov kub thiab qhov kub thiab txias:
Kev khiav hauj lwm kub: Ua kom cov khoom siv thauj khoom ntawm cov khoom siv (piv txwv li, cov ntsaws ruaj ruaj, feem ntau {{} degree rau 80 degree hauv kev siv cov ntawv thov).
Siab ntsuam xyuas: phim cov raj xa hluav taws xob lub siab (piv txwv li, 1. {{} Mpa mpa mpa mpa cia kom txaus, 2.5 MPa rau kev pab hloov tsheb).
2. Loading \/ unloading txoj kev thiab kev teeb tsa teeb tsa
Hauv qab vs. Sab saum toj Chaw thau khoom \/ thauj khoom:
Hauv qab chaw thau khoom \/ thauj khoom: Qhov kev nyiam xaiv rau hydrogen peroxide los txo cov vapor emission. Xaiv Al 2503- Hom Hauv Qab Kaw Caj npab (piv txwv li} nti} nti nrawm.
Sab saum toj Chaw thau khoom \/ thauj khoom: Used only in special cases (eg, older tank trucks), requiring AL1412-type top loading arms with vapor recovery systems.
Ib puag ncig kev teeb tsa:
Kev Siv Sab Nraum: Ua Ntej UV-resistant ntsaws ruaj ruaj thiab huab cua dav hlau stainless hlau tiav.
Hauv sab tsev Terminals: Tsom rau qhov chaw txuag (piv txwv li, kev sib xyaw ua ke hloov pauv kev teeb tsa).
3. Kev nyab xeeb thiab kev ua raws cai
Kev Tiv Thaiv Kev tawg:
Nco ntsoov tias lub chaw thau khoom sab caj npab tau cog lus rau dissipate hluav taws xob zoo li qub (tseem ceeb rau kev tiv thaiv kev tawm tsam ntawm hydrogen peroxide vapors).
Xaiv cov qauv ntawv pov thawj los ntawm FM \/ ATEX rau siv nyob rau hauv thaj chaw muaj kev phom sij.
Kev tiv thaiv xau:
Nruab nrog cov chaw so thaum muaj xwm txheej ceev (EBDVs) uas cia li discronect nyob rau hauv tsawg dua lossis sib npaug rau 500n nro kom tiv thaiv tau cov roj thaum lub tsheb npaj txhij.
Yuav tsum muaj ob npaug kev tsim qauv ntawm swivel pob qij txha (piv txwv li, PTFE thawj ntsaws ruaj ruaj + fluororubber thaub qab).
4. Flow tus nqi thiab pipeline specifications
Ntws Muaj Peev Xwm:
Laij cov neeg tsav tsheb txaus (piv txwv li, 50 m³ \/ {} nti taub hau ({{} nti kav dej (60 m³ \/ h).
Kev Sib Txuas Sib Txuas:
Xyuas kom meej cov fittings sai sai li qub nrog API 650 lossis DIN 2817, sib piv Tank Tsheb Inlets (ntau qhov ntau: DN5000).
Step-rau-step theem qauv xaiv cov txheej txheem
1. Txiav txim siab qhov chaw thau khoom \/ thauj khoom
Hauv qab no kaw chaw thau khoom \/ thau khoom: Pom zoo kom al2503 series (piv txwv li, al 2503-316 l -80}) rau cov kev tsim nyog niaj hnub nrog kev nyab xeeb txog kev nyab xeeb.
Qhib qhib chaw thau khoom \/ thau khoom: Xaiv Al1412 series (piv txwv li, al 1412-304-50}) rau cov chaw laus nrog tsawg txoj hauv qab nkag.
2. Xaiv cov khoom siv raws li kev pom zoo
30% H₂O₂: Siv SS304 (ASTM A 240 304) rau cov kav dej thiab pob qij txha.
>50% H₂O₂: Xaiv rau SS316L (ASTM A {1}} l) kom tiv thaiv pittorion.
Foob cov ntaub ntawv: PTFE (haum rau tsawg dua lossis sib npaug rau 60 degree) lossis perfluoroelastomer (FFKM) rau kev kub siab \/ siab-siab txog scenterarios.
3. Kho cov khoom siv kev nyab xeeb
Yuav tsum tau khoom siv:
Kev tawg thaum muaj xwm txheej ceev li cas (ebdvs) uas tsis siv neeg kaw teeb tsa.
Pob li qub rau ntws tswj (SS316L lub cev, PTFE lub rooj).
Yeem hloov kho tshiab:
Vapor rov qab kho rau kev tiv thaiv ib puag ncig.
Kev sib xyaw ua ke ntawm kev kub siab gauges thiab ntws meters rau kev soj ntsuam tiag tiag.
4. Txheeb xyuas cov kev qhia txhua yam
Nyias muaj nyias: Ua kom meej meej universal pob qij txha tso cai ntau dua lossis sib npaug ntawm 180 degree ntsug thiab 360 degree kab rov tav mus hloov chaw teeb tsa lub tsheb loj.
Qhov hnyav sib npaug: Xaiv qauv nrog Counterweight lub tshuab (piv txwv li, kev sib npaug thaum lub caij nplooj ntoos hlav) los txo qis cov neeg tsav tsheb lub sijhawm ua haujlwm.
Hom Tshuaj Hydrogen Peroxide Chaw thau khoom caj npab qauv thiab lawv cov nta
Al 2503-304: Ua los ntawm SS304, nrog DN50 \/ DN80 kev sib txuas, tus nqi siab tshaj plaws ntawm 40 m³ \/ h, thiab nruab nrog eBDVs thiab PTFE ntsaws ruaj ruaj. Haum rau kev tsim dav siv nrog 30% h₂o₂.
Al 2503-316 l: Tsim los ntawm SS316L, muaj kev sib txuas DN80 \/ DN100, tus nqi siab tshaj plaws ntawm 60 m³ \/ h, ob npaug rau-ntim tsim, thiab FM ntawv pov thawj. Qhov zoo tagnrho rau high-concentration h₂o₂ hauv cov nroj tsuag tshuaj.
Al 1412-316 l: Ua los ntawm SS316L, nrog DN50 kev twb kev txuas, tus nqi siab tshaj plaws ntawm 25 m³ \/ h, thiab cov khoom siv vapor rov qab thiab cov khoom siv hauv av. Haum rau sab saum toj chaw thau khoom hauv qhov chaw kaw.
Los ntawm cov kab ke ntsuas cov qauv no, tuaj yeem xaiv lub chaw thau khoom ntawm caj npab uas ntsuas kev nyab xeeb, ua haujlwm ntev rau hydrogen peroxide tuav.
