Cov rectifiers tooj liab yog cov khoom tseem ceeb hauv ntau yam txheej txheem kev lag luam, tshwj xeeb tshaj yog hauv kev lag luam electroplating thiab kev lag luam refining hlau. Cov rectifiers no ua lub luag haujlwm tseem ceeb hauv kev hloov pauv hluav taws xob (AC) mus rau hauv hluav taws xob ncaj qha (DC) rau kev electrolytic refining ntawm tooj liab. Kev nkag siab txog txoj cai ua haujlwm ntawm electrolytic tooj liab rectifiers yog qhov tseem ceeb rau kev nkag siab txog lawv qhov tseem ceeb hauv kev siv hauv kev lag luam.
Lub hauv paus ntsiab lus ua haujlwm ntawm lub tshuab hluav taws xob electrolytic tooj liab yog hloov AC mus rau DC los ntawm cov txheej txheem electrolysis. Electrolysis yog ib qho txheej txheem tshuaj lom neeg uas siv hluav taws xob los tsav cov tshuaj tiv thaiv tsis yog spontaneous. Hauv qhov xwm txheej ntawm kev ua kom tooj liab zoo, lub rectifier pab txhawb kev tso tooj liab ntshiab rau ntawm cathode los ntawm kev xa cov DC tam sim no tswj tau los ntawm cov kua tooj liab sulfate.
Cov khoom tseem ceeb ntawm lub tshuab hluav taws xob electrolytic tooj liab muaj xws li lub transformer, chav rectifying, thiab lub kaw lus tswj. Lub transformer yog lub luag haujlwm rau kev txo qis qhov hluav taws xob siab AC mus rau qhov hluav taws xob qis dua uas haum rau cov txheej txheem electrolytic. Lub chav rectifying, uas feem ntau muaj cov diodes lossis thyristors, hloov AC mus rau DC los ntawm kev tso cai rau cov hluav taws xob ntws hauv ib qho kev taw qhia xwb. Lub kaw lus tswj hwm qhov hluav taws xob tso zis thiab tam sim no kom ntseeg tau tias muaj cov xwm txheej tseeb thiab ruaj khov rau cov txheej txheem electrolytic refining.
Cov txheej txheem ntawm kev ua kom tooj liab electrolytic pib nrog kev npaj cov electrolyte, uas yog cov kua ntawm tooj liab sulfate thiab sulfuric acid. Lub anode, feem ntau yog ua los ntawm tooj liab tsis huv, thiab lub cathode, ua los ntawm tooj liab huv, raug muab tso rau hauv electrolyte. Thaum lub rectifier qhib, nws hloov cov khoom siv AC mus rau DC, thiab cov hluav taws xob ntws los ntawm anode mus rau cathode los ntawm electrolyte.
Ntawm qhov anode, cov tooj liab tsis huv yuav raug oxidation, tso cov ions tooj liab rau hauv cov electrolyte. Cov ions tooj liab no ces txav mus los ntawm cov kua thiab raug tso rau ntawm cathode ua tooj liab ntshiab. Qhov kev ntws tas mus li ntawm tam sim no thiab kev xaiv cov ions tooj liab tso rau ntawm cathode ua rau cov tooj liab huv, ua rau nws tsim nyog rau ntau yam kev siv hauv kev lag luam.
Lub hauv paus ntsiab lus ua haujlwm ntawm lub electrolytic tooj liab rectifier yog raws li cov kev cai tseem ceeb ntawm electrolysis, tshwj xeeb tshaj yog Faraday txoj cai. Cov kev cai no tswj hwm cov ntsiab lus ntawm electrolysis thiab muab lub hauv paus rau kev nkag siab txog kev sib raug zoo ntawm qhov ntau ntawm cov khoom tso rau hauv thiab qhov ntau ntawm cov hluav taws xob dhau los ntawm electrolyte.
Txoj cai lij choj thawj zaug ntawm Faraday hais tias qhov ntau ntawm kev hloov pauv tshuaj uas tsim los ntawm cov hluav taws xob tam sim no yog sib npaug rau qhov ntau ntawm cov hluav taws xob dhau los ntawm cov electrolyte. Hauv cov ntsiab lus ntawm kev ua kom tooj liab electrolytic, txoj cai lij choj no txiav txim siab qhov ntau ntawm cov tooj liab ntshiab tso rau ntawm cathode raws li qhov tam sim no dhau los ntawm lub rectifier thiab lub sijhawm ntawm cov txheej txheem electrolysis.
Txoj cai thib ob ntawm Faraday cuam tshuam qhov ntau ntawm cov khoom tso rau thaum lub sijhawm electrolysis rau qhov hnyav sib npaug ntawm cov khoom thiab qhov ntau ntawm cov hluav taws xob dhau los ntawm electrolyte. Txoj cai no yog qhov tseem ceeb hauv kev txiav txim siab qhov ua tau zoo ntawm cov txheej txheem electrolytic tooj liab refining thiab xyuas kom meej tias muaj kev tsim cov tooj liab zoo.
Ntxiv rau Faraday txoj cai, txoj cai ua haujlwm ntawm electrolytic tooj liab rectifiers kuj suav nrog kev xav txog kev tswj hwm voltage, kev tswj tam sim no, thiab kev ua haujlwm zoo ntawm cov txheej txheem refining. Lub rectifier lub kaw lus tswj hwm ua lub luag haujlwm tseem ceeb hauv kev tswj hwm qhov voltage thiab tam sim no xav tau, uas yog qhov tseem ceeb rau kev ua tiav qhov zoo thiab kev huv ntawm cov tooj liab refined.
Tsis tas li ntawd xwb, qhov ua tau zoo ntawm cov txheej txheem electrolytic tooj liab yog cuam tshuam los ntawm cov yam xws li kub, kev sib xyaw ntawm cov electrolyte, thiab kev tsim ntawm lub cell electrochemical. Cov yam no tuaj yeem cuam tshuam rau qhov nrawm ntawm kev tso tooj liab, kev siv zog ntawm lub rectifier, thiab tag nrho cov nqi-kev ua haujlwm ntawm kev ua haujlwm refining.
Xaus lus, lub hauv paus ntsiab lus ua haujlwm ntawm electrolytic tooj liab rectifiers yog rooted nyob rau hauv cov ntsiab lus ntawm electrolysis thiab hluav taws xob engineering. Los ntawm kev hloov AC mus rau DC thiab tswj lub voltage thiab tam sim no rau cov txheej txheem electrolytic refining, cov rectifiers no ua rau muaj kev tsim cov tooj liab zoo, ntshiab rau ntau yam kev siv hauv kev lag luam. Kev nkag siab txog qhov nyuaj ntawm electrolytic tooj liab rectifiers yog qhov tseem ceeb rau kev ua kom zoo dua thiab ua tau zoo ntawm kev ua haujlwm tooj liab refining hauv thaj chaw niaj hnub no.
