Kev phom sij rau ib puag ncig ntawm cov chaw ua xuab zeb
Kev tsim cov xuab zeb yuav ua rau muaj ntau yam kev phom sij rau ib puag ncig hauv cov txheej txheem tsim khoom, feem ntau suav nrog:
1. Kev ua qias tuaj ntawm huab cua: Cov txheej txheem casting yuav tsim cov hmoov av ntau thiab cov pa phem, xws li carbon monoxide, nitrogen oxide, sulfide, thiab lwm yam, cov pa phem no yuav muaj kev cuam tshuam loj heev rau qhov zoo ntawm huab cua ib puag ncig.
2. Kev ua qias dej: cov txheej txheem casting yuav tsim cov dej khib nyiab, suav nrog dej txias, dej ntxuav, dej khib nyiab kho tshuaj, thiab lwm yam. Cov dej khib nyiab no yog tias tso tawm ncaj qha yam tsis tau kho, yuav ua rau muaj kev ua qias rau lub cev dej.
3 Cov khib nyiab khov kho: Cov txheej txheem casting yuav tsim cov khib nyiab khov kho xws li cov xuab zeb pov tseg, cov hlau seem thiab cov slag, uas, yog tias tsis kho kom zoo, yuav nyob hauv av ntau thiab ua rau av thiab dej hauv av muaj kuab paug.
4. Kev ua qias tuaj ntawm suab nrov: kev ua haujlwm ntawm tshuab thiab kev tuav cov khoom siv hauv cov txheej txheem casting yuav tsim suab nrov, uas yuav ua rau muaj kev ua qias tuaj ntawm suab nrov rau ib puag ncig.
Cov kev daws teeb meem
Yuav kom txo tau qhov kev puas tsuaj rau ib puag ncig ntawm cov xuab zeb foundry, cov kev ntsuas hauv qab no tuaj yeem ua tau:
1. Kev kho plua plav thiab roj teeb meem: cov plua plav tawm tuaj yeem ntxuav tau los ntawm txoj kev ntub lossis qhuav, cov roj teeb meem tuaj yeem tswj tau los ntawm kev hloov txoj kev sib xyaw ntawm cov pa roj carbon monoxide thiab nitrogen oxide, kev siv cov pa roj carbon activated, silica gel, activated alumina thiab lwm yam adsorbants los daws cov pa roj sulfur, hydrogen chloride thiab lwm yam.
2. Kev kho dej khib nyiab: Rau cov dej khib nyiab uas tsim los ntawm cov txheej txheem casting, nag lossis daus, lim dej, cua ntab, coagulation thiab lwm txoj hauv kev tuaj yeem siv los tshem tawm cov khoom khov kho hauv cov dej khib nyiab, thiab kev kho mob aerobic oxidation tuaj yeem siv los txo cov tshuaj oxygen thov thiab biochemical oxygen thov hauv cov dej khib nyiab.
3. Kev kho cov khib nyiab khov: cov xuab zeb pov tseg tuaj yeem siv rau hauv qhov chaw pov tseg kom huv lossis siv ua cov khoom sib xyaw rau cov ntaub ntawv tsim kho, thiab cov slag tuaj yeem sau thiab xa mus rau cov chaw tsim cement rau kev siv ua cov khoom sib xyaw.
4. Kev tswj suab nrov: siv cov khoom siv suab nrov qis, xws li lub kiv cua suab nrov qis, thiab teeb tsa rau hauv lub tshuab nqus pa lossis siv txoj kev ntawm chav rwb thaiv suab thiab lub tshuab nqus pa los tswj qhov chaw suab nrov.
5. Kev txuag hluav taws xob thiab kev txo cov pa phem: txhim kho kev siv hluav taws xob kom zoo, txo kev siv hluav taws xob, txo cov pa roj carbon dioxide, thiab siv cov thev naus laus zis hluav taws xob huv thiab cov pa roj carbon tsawg.
6. Kev tsim qauv kev tswj hwm ib puag ncig: tsim kom muaj ib lub txheej txheem tswj hwm ib puag ncig los saib xyuas thiab tswj txhua yam kev ua qias tuaj uas tau tsim tawm hauv cov txheej txheem tsim khoom thiab xyuas kom meej tias kev siv cov kev ntsuas tiv thaiv ib puag ncig zoo.
Los ntawm kev siv cov kev ntsuas no, cov chaw tsim cov xuab zeb tuaj yeem txo lawv qhov cuam tshuam tsis zoo rau ib puag ncig thiab ua tiav kev txhim kho ruaj khov.
