1. General Installation Overview
Los ntawm tag nrho cov chaw saib, cov electrowinning hlwb yog teem nyob rau hauv parallel kab nyob rau hauv lub steel qauv, nrog ib tug central taug kev rau kev khiav hauj lwm thiab txij nkawm. Cov theem no sawv cev rau nruab nrab - mus rau - theem lig ntawm kev teeb tsa, suav nrog:
- Cell positioning, leveling, thiab alignment
- Kev txhim kho cov kav dej
- Kev txhim kho ntawm cov cuab yeej pabcuam (kev taug kev, kev txhawb nqa)
- Anti-corrosion thiab sealing ua haujlwm
Ntawm cov no, parallelism thiab leveling ntawm cov hlwb yog qhov tseem ceeb thiab feem ntau yog tswj nyob rau hauv millimeter kam rau ua kom ntseeg tau tias niaj hnub kev faib tawm.
2. Electrolyte Distribution Piping Hauv Cell
Daim duab thib ob qhia meej meej txog cov khoom siv hluav taws xob sab hauv.
2.1 Cov qauv ntawm kev faib cov kav dej
Lub kaw lus feem ntau siv PVC los yog lwm yam corrosion-cov ntaub ntawv uas tiv taus nyob rau hauv cov duab plaub los yog voj configuration nyob rau hauv qab ntawm lub cell. Nws lub luag haujlwm tseem ceeb suav nrog:
- Uniform faib ntawm electrolyte
- Kev zam ntawm thaj chaw tuag lossis siab - thaj chaw nrawm
- Kev txhim kho tam sim no efficiency thiab hlau deposition uniformity
- Cov kav dej feem ntau yog ntsia ze rau hauv qab ntawm lub tank thiab tsau nrog kev txhawb nqa.
2.2 Cov ntsiab lus tseem ceeb ntawm kev teeb tsa
(1) Qib Tswj
Cov kav dej yuav tsum tau nruab rau kab rov tav kom ntseeg tau tias muaj kev faib tawm.
(2) Kev kho
- Ruaj ntseg nrog cov brackets los yog clamps kom raug
- Tiv thaiv kev txav los yog kev vibration thaum ua haujlwm
(3) Kev sib khi ntawm kev sib txuas
- Xyuas kom nruj sealing ntawm cov pob qij txha thiab kev sib txuas
- Tiv thaiv kom tsis muaj pa tawm lossis cua nkag
(4) Kev tiv thaiv -Kev ntsuas thaiv
- Xyuas kom cov qhov hluav taws xob faib sib npaug
- Tiv thaiv cov khib nyiab los ntawm kev nkag thaum lub sijhawm teeb tsa
3. Cov qauv ntawm tes thiab hauv qab sib koom ua ke (Grouting)
Yuav Ua Li Cas Grouting Ntawm EW Cells
3.1 Lub hom phiaj ntawm kev sib koom ua ke
Kev sib khi hauv qab yog ib qho tseem ceeb tab sis feem ntau underestimated kauj ruam. Nws lub luag haujlwm tseem ceeb yog:
- Tiv thaiv electrolyte to
- Txhim kho cov qauv kev ruaj ntseg
- Tiv thaiv cov khoom siv ntawm cov khoom siv corrosive
3.2 Cov khoom siv
- Epoxy mortar
- Anti-corrosion sealants
- Acid- thiab alkali- tiv thaiv kev sib koom ua ke
3.3 Cov ntsiab lus tseem ceeb ntawm kev tsim kho
(1) Kev npaj nto
- Ntxuav plua plav, roj, thiab noo noo
- Xyuas kom huv si qhov chaw sib txuas
(2) Ua kom zoo
- Sau cov pob qij txha kom tsis muaj voids
- Thov hauv cov khaubncaws sab nraud povtseg yog tias tsim nyog
(3) Nto tiav
- Xyuas kom du thiab txawm nto
- Tsis txhob ua kua nplaum
(4) Lub sijhawm kho
- Ua raws li cov khoom specifications nruj me ntsis
- Tsis txhob muab tso rau hauv kev pabcuam ua ntej kho tag nrho
4. Cov teeb meem tshwm sim thaum nruab
Raws li qhov kev paub ntawm qhov chaw, cov teeb meem ib txwm muaj xws li:
- Misalignment ntawm cov hlwb cuam tshuam rau cathode tuav
- Kev tso dej tsis zoo ua rau cov dej tsis sib xws
- Kev sib koom ua ke tsis txaus ua rau xau
- Kev kho cov yeeb nkab tsis zoo ua rau kev hloov pauv thaum ua haujlwm
Cov teeb meem no feem ntau dhau los ua qhov tseem ceeb thaum ua haujlwm thiab tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub cev.
5. Cov lus xaus
Lub installation ntawm electrowinning hlwb tsis yog hais txog kev tso cov khoom siv xwb- nws yuav tsum muaj kev ua haujlwm siab, ua tib zoo saib xyuas kom meej, thiab tswj cov txheej txheem nruj. Cov yam tseem ceeb muaj xws li:
- Installation raug ntawm cov hlwb
- Uniformity ntawm electrolyte tis
- Kev sib khi kom raug thiab tiv thaiv - kev kho corrosion
Cov no cuam tshuam ncaj qha electrowinning efficiency, cov khoom zoo, thiab cov khoom siv lifespan.
Los ntawm cov xwm txheej ntawm lub xaib tau pom, tag nrho cov kev teeb tsa zoo yog qhov zoo, nrog rau zoo - kev teeb tsa thiab cov qauv. Txawm li cas los xij, ua tib zoo saib xyuas kom meej-tshwj xeeb tshaj yog kev sib khi thiab kev kho cov yeeb nkab- tseem yog qhov tseem ceeb los xyuas kom meej ntev - lub sijhawm ua haujlwm ruaj khov.
