Cov ntsiab lus tseem ceeb rau kev tswj cov khoom siv dej ultrapure

Kev tu thiab tu cov khoom siv dej ultrapure yog qhov tseem ceeb rau kev ua kom nws lub sijhawm ntev - haujlwm ruaj khov. Rau cov neeg siv hauv cheeb tsam Jiangsu, Zhejiang, thiab Shanghai, peb muab pub dawb rau ntawm -cov kev pabcuam hauv chaw, tuaj txog hauv 24 teev. Hauv kev tsim khoom thiab kev ua haujlwm hauv chav kuaj, cov khoom siv dej ntshiab yog qhov tseem ceeb raws li "lifeline." Raws li ib qho ntawm cov kev pabcuam hauv tsev thaum ntxov tshaj plaws tshwj xeeb hauv kev saib xyuas cov khoom siv dej ultrapure (tsim nyob rau hauv 2010), peb tau muab cov cuab yeej tu thiab tswj kev pabcuam rau ntau tshaj 600 lub tuam txhab, tiv thaiv cov dej ntshiab ntawm txhua qhov dej nrog peb cov thev naus laus zis thev naus laus zis.

I. Cov Txheej Txheem Khoom Siv thiab Cov Ntsiab Lus Saib Xyuas Ib qho dej ultrapure feem ntau muaj pretreatment, thim rov qab osmosis (RO), electrodeionization (EDI), thiab cov txheej txheem dav hlau polishing. Cov ntsiab lus tseem ceeb ntawm kev saib xyuas rau txhua theem yog raws li hauv qab no:

1. Pretreatment Unit: Tsis tu ncua tshuaj xyuas ntau- xov xwm lim, cov pa roj carbon adsorber, thiab cov khoom muag muag kom tsis txhob muaj cov khoom siv hauv qab los ntawm cov khoom colloids, organic teeb meem, thiab hardness ions.

2. RO Membrane System: Saib xyuas cov dej hauv dej siab, cov khoom siv dej, thiab cov nqi rov qab; tsis tu ncua chemically huv membrane ntsiab kom tiv thaiv scaling thiab fouling.

3. EDI Module: Kho qhov tam sim no thiab qhov hluav taws xob mus rau qhov tsim nyog ntau yam, thiab qee zaus acid- ntxuav thiab rov tsim cov ion txauv resin los tiv thaiv polarization.

4. Terminal Polishing Unit: Tsis tu ncua hloov cov khoom siv nitrogen sealing thiab UV module ntawm lub tank dej ultrapure kom ntseeg tau tias cov dej zoo nyob ruaj khov siab dua 18.2 MΩ·cm.

II. Hloov Lub voj voog thiab cov qauv rau cov khoom siv tseem ceeb

1. Pretreatment Filter Cartridge: Hloov txhua 1-3 lub hlis. Hloov ua ntej yog tias qhov sib txawv siab ntau dua lossis sib npaug ntawm 0.1MPa lossis dej turbidity tshaj tus qauv.

2. RO Membrane Element: Lifespan 2-3 xyoos. Hloov thaum lub permeate ntws tus nqi txo los ntawm 15% los yog desalination tus nqi qis dua 95%.

3. EDI Module: Hloov txhua 5-8 xyoo. Tshawb xyuas lossis hloov yog tias qhov permeate resistivity tseem qis dua 16 MΩ·cm.

4. Polishing Resin: Hloov txhua xyoo los tiv thaiv TOC thiab ion nag lossis daus los ntawm kev cuam tshuam cov dej ntws zoo.

III. Cov txheej txheem tu txhua hnub

1. Kev tshuaj xyuas txhua hnub: Sau cov ntaub ntawv muaj txiaj ntsig / dej permeate, siab, thiab cov ntaub ntawv ntws, thiab tshawb xyuas cov kev hloov pauv txawv txav . 2. Kev Kho Txhua Lub Limtiam: Tshawb xyuas cov raj xa dej, ntxuav cov impurities los ntawm cov lim ua ntej -, thiab ntsuas cov cuab yeej online.

3. Kev tu txhua hli: Rov qab ntxuav lub pretreatment chav tsev, tshuaj ntxuav lub RO system, thiab kuaj qhov ruaj khov ntawm EDI tam sim no.

4. Kev Txhim Kho Txhua Xyoo: Tshawb xyuas cov twj tso kua mis, lub valve, cov twj paj nruag, thiab cov tshuab hluav taws xob; hloov cov aging qhov chaw thiab tsim ib daim ntawv qhia txog txij nkawm.

IV. Qhov tseem ceeb ntawm kev xaiv ib tus neeg muab kev ntseeg siab

1. Cov Khoom Siv Tseem Ceeb (OEM) Consumables Guarantee: Cov neeg muag khoom ntseeg tau muab cov lim cartridges thiab cov khoom siv membrane sib haum nrog cov khoom siv, zam cov teeb meem kev sib raug zoo uas tuaj yeem ua rau kev ua haujlwm tsis zoo.

2. Kev Pabcuam sai sai: Cov neeg muab khoom nrog cov pab pawg hauv zos tuaj yeem muab kev saib xyuas xwm txheej ceev hauv 48 teev, txo qis kev poob qis.

3. Kev Txhawb Nqa Lub Neej Tag Nrho: Cov neeg muag khoom ntseeg tau muab kev tshuaj xyuas dej zoo, kev cob qhia kev saib xyuas, thiab cov txheej txheem kev ua kom zoo dua qub, txuas cov cuab yeej siv lub neej ntev li 10% -20%.

4. Kev Tswj Tus Nqi: Kos npe rau daim ntawv cog lus ntev - daim ntawv cog lus txij nkawm tuaj yeem kaw cov nqi siv tau, zam kev cuam tshuam ntawm kev lag luam hloov pauv ntawm cov nqi khiav lag luam.

Kev npaj kho cov cuab yeej siv tshawb fawb yuav tsum tau coj mus rau hauv tus account cov yam ntxwv ntawm cov txheej txheem, kev tswj cov khoom siv, thiab kev sib koom tes ntawm cov neeg siv khoom. Nws raug nquahu kom cov neeg siv khoom tseem ceeb rau cov neeg muab kev pabcuam uas muaj ntau tshaj 10 xyoo ntawm kev ua haujlwm hauv kev lag luam thiab tshawb xyuas cov txiaj ntsig kev saib xyuas los ntawm kev kuaj dej tsis tu ncua kom ntseeg tau tias lub sijhawm ntev - lub sijhawm ua haujlwm ruaj khov ntawm cov dej ultrapure.
