Backgrund of Oil-Cov dej khib nyiab muaj
1. Basic Composition ntawm Industrial Wastewater
Cov dej khib nyiab muaj feem ntau yog tsim los ntawm cov haujlwm xws li petrochemical ua, kev tsim khoom siv tshuab, metallurgy, thiab mining. Nws muaj pes tsawg leeg yog complex, feem ntau muaj suspended solids, emulsified roj, organic tshuaj, thiab ntau yam inorganic ions.Hauv particular, oily wastewater muaj roj nyob rau hauv dawb, dispersed, los yog emulsified daim ntawv, ua rau nws nyuaj rau kho.
2. Cov teeb meem tseem ceeb hauv kev kho cov dej khib nyiab oily
Cov txheej txheem xws li kev sib cais ntawm lub ntiajteb txawj nqus lossis flotation yog siv tau rau cov roj dawb tab sis muaj kev txwv tsis pub siv cov roj emulsified ruaj khov, feem ntau ua rau kev kho tsis tiav lossis kev ua haujlwm tsis ruaj khov. Yog li ntawd,ruaj khov thiab ua tau zoo tshaj kev sib cais technologiestau dhau los ua qhov tseem ceeb hauv kev lag luam.
Technical Principles of Ceramic Membranes in Oil-Kev sib cais dej
1. Cov yam ntxwv ntawm Ceramic Membranes
Ceramic membranes feem ntau yog tsim los ntawm alumina lossis zirconia(Alumina daim nyias nyias, zirconia membrane). Lawv muaj qhov sib txawv ntawm qhov pore loj faib, kub tsis kam, corrosion kuj, thiab siab txhua yam muaj zog.Cov yam ntxwv no ua rau lawv haum rau cov dej tsis zoo.
2. Kev sib cais
Ceramic membranes ua tiav cov roj- dej sib cais los ntawmsievingthiabkev cuam tshuam ntawm interfacial:
● Cov roj ntsha loj dua tuaj yeem cuam tshuam ncaj qha los ntawm daim nyias nyias pores;
● Rau cov roj emulsified, lub hydrophilic membrane nto thiab kev khiav hauj lwm siab sib txawv txhawb dej molecules kom dhau los ntawm preferentially thaum roj khaws cia;
Thaum lub sijhawm ua haujlwm dynamic,hla -flow filtrationtxo cov membrane nto fouling thiab txhim kho kev ua haujlwm ruaj khov. Qhov no kuj yog qhov laj thawj tseem ceeb vim li casceramic membrane rau roj dej sib caisthev naus laus zis tau nce zuj zus hauv cov ntawv thov kev lag luam.
Txheej Txheem Flow thiab Kev Ua Haujlwm Logic
1. Txheej txheem Flow Overview
Tom qab nkag mus rau hauv qhov system, oily wastewater feem ntau ua raws li cov kauj ruam hauv qab no:
● Ua ntej-kev kho mob: tshem tawm cov khoom loj kom txo tau cov kab mob fouling;
● Ceramic membrane filtration: core cais chav rau roj- dej sib cais;
● Permeate rov siv dua lossis tso tawm ua raws li cov qauv;
● Kev sau thiab kev kho ntawm cov roj concentrated theem.
Tag nrho cov txheej txheem yog compact thiab haum rau modular integrated tsim.
2. Cov yam ntxwv ua haujlwm
● Muaj peev xwm muaj peev xwm ua haujlwm tsis tu ncua
● Kev hloov pauv siab rau kev hloov pauv dej zoo
● Kev ua haujlwm ruaj khov rov qab ua haujlwm tom qab ntxuav
● Qib siab ntawm automation
Piv nrog rau cov ntaub ntawv membrane cov pa, cov khoom siv ceramics qhia tau tias muaj kev ruaj ntseg zoo dua hauv cov chaw lag luam complex.
Kev siv tus nqi ntawm cov roj sib cais
1. Rov qab thiab rov siv txoj hauv kev
Cov roj sib cais los ntawm cov khoom siv ceramic tuaj yeem raug coj mus rau ntau txoj kev kho mob nyob ntawm nws cov purity:
● Rov qab thiab siv los ua roj
● Rov qab mus rau cov txheej txheem tsim khoom siv rov qab siv dua
● Ntxiv refined thiab siv los ua cov khoom siv raw
2. Cov txiaj ntsig ntawm ib puag ncig thiab kev lag luam
Cov roj rov qab tsis tsuas yog txo cov pa paug tawm xwb tab sis kuj txo cov peev txheej pov tseg, ua tiav ob qho tib si ib puag ncig thiab kev ua kom zoo dua.
Daim ntawv thov kev xyaum ntawm Taihe Environmental Protection's Ceramic Membrane Technology
Hauv kev lag luam oily wastewater kho scenarios, ib qho khoom siv membrane feem ntau tsis txaus los tswj cov dej tsis zoo thiab kev ua haujlwm ntev - lub sijhawm ua haujlwm. Yog li ntawd,integrated tsim muaj peev xwm los ntawm cov ntaub ntawv mus rau systems yog qhov tseem ceeb. Kev xyaum ntawm Taihe Environmental Protection nyob rau hauv lub tshav pob ntawm ceramics yog lub hauv paus rau txoj kev no.
Taihe txais cov ntaub ntawv inorganic ceramic raws li alumina thiab zirconia, tsim cov qauv porous ruaj khov los ntawm siab -kub sintering. Qhov no ua rau daim nyias nyias kom muaj kev sib cais qhov tseeb thaum muab cov neeg kho tshuab muaj zog thiab tiv thaiv corrosion. Hauv kev kho cov dej khib nyiab tiag tiag, cov khoom siv no tsis tshua muaj kev cuam tshuam los ntawm cov kab mob organic thiab tuaj yeem ua haujlwm ruaj khov txawm tias hauv cov roj emulsified.
Nyob rau qib kev thov engineering, Taihe tsis tsuas yog muab cov khoom siv rau hauv daim nyias nyias tab sis muab cov khoom siv ua ke nrog cov khoom siv ua ntej -kev kho mob, kev pom kev pom, thiab kev tu vaj tse rau hauv ib qho kev ua tiav. Lub kaw lus feem ntau ua haujlwm nyob rau hauv cross-Flow filtration hom, tso cai rau cov dej khib nyiab mus txuas ntxiv mus thoob plaws hauv daim nyias nyias, yog li txo cov roj deposition thiab cuam tshuam fouling. Hom kev ua haujlwm no pab tswj cov dej ntws ruaj khov zoo nyob rau hauv cov xwm txheej hloov pauv.
Los ntawm kev pom kev ua haujlwm, qhov zoo ntawm cov khoom siv ceramic tsis txwv rau kev ua haujlwm sib cais tab sis kuj suav nrog kev ruaj khov hauv kev ua haujlwm. Tom qab fouling, kev ua tau zoo ntawm daim nyias nyias tuaj yeem rov qab los ntawm kev tu txhua hnub yam tsis muaj kev cia siab rau kev saib xyuas nyuaj, thiab kev ua haujlwm tsis zoo vim kev hloov pauv kev ua haujlwm raug txo qis. Qhov no yog ib qho tseem ceeb tshwj xeeb hauv kev lag luam tsis tu ncua.
Sib piv kev nkag siab nrog lwm cov Membrane Technologies
Hauv kev xaiv cov tswv yim, qee cov neeg siv sib piv cov txheej txheem sib txawv, xws li siv cov khoom siv organic zoo li hyflux uf membrane. Nyob rau hauv kev sib piv, ceramic membranes muaj zog tiv thaiv fouling, ntev kev pab cuam lub neej, thiab ntau ruaj khov ua hauj lwm, tshwj xeeb tshaj yog haum rau siab - nyuaj industrial wastewater kho.
Tsis tas li ntawd, cov khoom siv ceramics kuj yog ib feem tseem ceeb ntawm cov khoom sivceramic membranes rau kev kho dej khib nyiabtechnology system thiab maj mam dhau los ua ib qho kev taw qhia tseem ceeb rau kev txhim kho kev lag luam dej.
Xaus
Ceramic membrane technology tuaj yeem ua tiav cov roj- dej sib cais hauv cov dej khib nyiab, tshwj xeeb tshaj yog ua kom pom kev ruaj khov hauv kev kho cov roj emulsified thiab cov dej tsis zoo. Los ntawm cov txheej txheem tsim nyog thiab kev sib koom ua ke, nws tsis yog tsuas yog ua kom dej rov qab siv dua xwb tab sis kuj pab txhawb cov peev txheej roj rov qab. Nrog rau kev nruj kev lag luam ib puag ncig kev cai, daim ntawv thov Scope ntawm ceramic membrane tshuab txuas ntxiv nthuav dav.
