Cov teeb meem thiab kev daws teeb meem hauv cov txheej txheem ntxuav cov kua qaub

Txoj kev pickling yog siv dav hauv kev lag luam steel ntau lawm, txawm li cas los xij vim nws qhov nyuaj thiab qhov tsis sib xws ntawm ib puag ncig, txawm li cas los xij, muaj qee qhov teeb meem tsis txawv txav hauv kev ua haujlwm tiag tiag. Cov kws tshaj lij kev lag luam tau sau tseg ob peb lo lus teb muaj zog los daws cov teeb meem no.

Ua ntej, muaj teeb meem nrog tshwj xeeb ntawm acid pickling. Qee lub sij hawm tuaj yeem muaj cov xwm txheej uas qhov cuam tshuam tsis zoo, uas suav nrog kev ua kom huv tsis txaus, tshem tawm tsis tiav ntawm cov txheej hauv pem teb oxide, thiab lwm yam. Qhov no tsis tu ncua vim yog qhov tsis zoo ntawm cov lus teb pickling thiab lax kub tswj. Cov lus teb yog kev tshawb fawb muab tso ua ke cov kua qaub ntxuav cov lus teb feem ntau raws li tag nrho ntawm cov yam ntxwv ntawm ntau yam steel cov ntaub ntawv, uas suav nrog kev kho acid concentration, nrog rau cov additives, thiab lwm yam; Qhov thib 2 yog muab tso rau hauv qhov ntsuas kub tswj qhov system, nthuav tawm thiab hloov qhov kub ntawm lub sijhawm tiag tiag, thiab ua kom muaj kev ruaj khov ntawm cov txheej txheem tsis.

Tom ntej no yog qhov nyuaj ntawm txoj kev tiv thaiv. Thaum lub sij hawm pickling txoj kev, corrosive gases uas muaj xws li hydrogen thiab chlorine tsis muaj teeb meem generated. Kev tswj tsis raug tuaj yeem ua rau muaj kev tiv thaiv kev phom sij uas suav nrog cov neeg ua haujlwm lom thiab cov kab mob corrosion. Cov lus teb yog: ntawm ib sab tes, txhim khu lub rhiav huab cua txaus ntaus ntawv kom paub tseeb tias ib qho chaw ua haujlwm zoo heev; Ntawm qhov tod tes, teeb tsa cov cuab yeej tiv thaiv raug cai thiab muab kev kawm rau kev siv cov txheej txheem tiv thaiv ntiag tug.

Ib zaug ntxiv, muaj qhov nyuaj ntawm ib puag ncig cov pa phem. Yog tias cov dej khib nyiab thiab cov roj tso pa tawm los ntawm kev ntxuav cov kua qaub tsis ua haujlwm zoo, lawv tuaj yeem ua rau muaj kuab paug rau qhov chaw nyob. Cov lus teb yog ua kom cov dej khib nyiab zoo tshaj plaws uas suav nrog kev sib cais ntawm daim nyias nyias thiab hloov ion rau kev rov ua dua thiab rov siv dua; Qhov thib 2 yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tshem tawm cov kab mob, nws yog ib qho tsim nyog yuav tsum ua raws li cov txheej txheem ntawm cov pa roj carbon monoxide, uas suav nrog cov kua qaub purifiers, activated carbon adsorption devices, thiab lwm yam.

Thaum kawg, muaj qhov nyuaj ntawm kev siv hluav taws xob. Txoj kev pickling feem ntau hu rau ib qho loj ntawm qhov sov thiab muaj zog siv ntau dhau. Cov lus teb yog kom optimize txoj kev mus nrog lub drift thiab tswj lub pickling lub sij hawm thiab kub tsim nyog; Thib ob, cov tsheb txuag hluav taws xob thiab kev tswj hwm cov txheej txheem tau ua raws li kom txo qis zog siv hluav taws xob; Lub 1/3 yog rov ua dua cov khoom pov tseg warmness generated nyob rau hauv lub chav kawm ntawm txoj kev pickling, uas muaj xws li siv nws rau cua sov nyob rau hauv ntau yam txheej txheem.
