Environmental phom sij ntawm cov xuab zeb foundries
Sand foundry yuav ua rau muaj kev phom sij rau ib puag ncig hauv cov txheej txheem tsim khoom, feem ntau suav nrog:
1. Cov pa phem: Cov txheej txheem casting yuav tsim cov plua plav thiab cov pa phem ntau, xws li carbon monoxide, nitrogen oxide, sulfide, thiab lwm yam, cov pa phem no yuav ua rau muaj kev cuam tshuam loj rau huab cua nyob ib puag ncig.
2. Cov dej qias neeg: cov txheej txheem casting yuav tsim cov dej khib nyiab, nrog rau cov dej txias, dej ntxuav, tshuaj kho dej khib nyiab, thiab lwm yam., cov dej khib nyiab no ncaj qha tawm tsis kho, yuav ua rau muaj kuab paug rau lub cev dej.
3 Cov khoom pov tseg: Cov txheej txheem casting yuav tsim cov khoom pov tseg xws li cov xuab zeb pov tseg, cov khib nyiab hlau thiab slag, uas, yog tias tsis kho kom zoo, yuav nyob hauv ntau thaj av thiab ua rau cov av thiab dej hauv av muaj kuab lom.
4. Cov pa phem tsis zoo: kev ua haujlwm txhua yam thiab cov khoom siv hauv cov txheej txheem casting yuav ua suab nrov, uas yuav ua rau muaj suab nrov rau ib puag ncig.
Txoj kev daws teeb meem
Txhawm rau txo qhov kev puas tsuaj ib puag ncig ntawm cov xuab zeb, cov kev ntsuas hauv qab no tuaj yeem ua:
1. Kev kho cov plua plav thiab cov pa phem: cov plua plav tawm tuaj yeem ua kom huv los ntawm txoj kev ntub dej los yog qhuav, cov pa phem tuaj yeem tswj tau los ntawm kev hloov cov pa roj carbon monoxide thiab nitrogen oxide emissions, siv cov activated carbon, silica gel, activated alumina. thiab lwm yam adsorbants los cuam tshuam nrog sulfur gas, 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, pom, huab cua flotation, coagulation thiab lwm txoj kev tuaj yeem siv los tshem tawm cov khib nyiab hauv cov dej khib nyiab, thiab kev kho aerobic oxidation tuaj yeem siv los txo cov tshuaj oxygen thov thiab biochemical. oxygen xav tau hauv cov dej khib nyiab.
3. Kev kho cov khib nyiab pov tseg: cov xuab zeb pov tseg tuaj yeem ua kom huv si los yog siv los ua cov khoom sib xyaw rau cov khoom siv hauv tsev, thiab cov slag tuaj yeem sau thiab xa mus rau cov nroj tsuag cement siv los ua cov khoom sib xyaw.
4. Kev tswj lub suab nrov: siv cov khoom siv suab nrov, xws li cov kiv cua tsis tshua muaj suab nrov, thiab nruab rau hauv lub tshuab nqus tsev vacuum los yog siv cov txheej txheem ntawm lub suab rwb thaiv tsev chav thiab muffler channel los tswj lub suab nrov.
5. Kev txuag hluav taws xob thiab txo qis emission: txhim kho kev siv hluav taws xob, txo kev siv hluav taws xob, txo cov pa roj carbon dioxide emissions, thiab txais kev siv lub zog huv thiab cov pa roj carbon tsawg.
6. Kev tswj hwm ib puag ncig kev tsim qauv: tsim kom muaj kev tswj hwm ib puag ncig los saib xyuas thiab tswj txhua yam kev ua qias tuaj hauv cov txheej txheem tsim khoom thiab xyuas kom muaj txiaj ntsig zoo ntawm kev tiv thaiv ib puag ncig.
Los ntawm kev ua raws li cov kev ntsuas no, cov xuab zeb foundries tuaj yeem txo qhov cuam tshuam tsis zoo rau ib puag ncig thiab ua tiav kev txhim kho kom ruaj khov.
