Yuav ua li cas txo cov emissions kom tau raws li cov qauv VOC emissions
Peb yog ib lub tuam txhab luam ntawv loj hauv Shenzhen Tuam Tshoj. Peb muaj cov phau ntawv luam tawm, phau ntawv xov xwm luam ntawv, phau ntawv luam ntawv, phau ntawv nyuaj, phau ntawv luam tawm, phau ntawv luam tawm, phau ntawv luam tawm, lub thawv ntim, daim qhia ntawv, txhua yam ntawm PVC, cov ntawv luam tawm, ntawv sau cia, hom tshwj xeeb ntawv xim luam tawm khoom, kev ua si cardand li ntawd.

Nyob rau hauv Printing Printing Pollutant Control thiab lub rooj sab laj Technology Forum, Nws Zhengchu, tus thawj xibfwb ntawm Shanghai Academy of Environmental Sciences, tau hais lus zoo nrog kev txhais cov "Printing Industry Air Pollutant Emission Standards and Control Policies". Qee qhov kev hais lus tau muab tso ua ke. Muab kev qhia thiab kev siv rau cov tuam txhab kev luam ntawv kom txo tau cov VOCs emissions.
VOCs yog dab tsi?
Ib qho chaw organic uas koom rau hauv atmospheric reactchemical lom neeg los yog ntsuas los yog cov account rau ib qho chaw organic uas tau muab teev tseg raws li txoj kev qhia tseg.
Hom Vocs: benzene series, roj av roj cov hlab ntsha, cov tshuaj organic chlorides, Freon series, organic ketones, amines, alcohols, ethers, esters, acids, thiab cov zoo li. (Common in the printing industry: esters, alcohols, ketones, benzene, etc.)
Kev luam tawm kev lag luam
Cov chaw VOCs nyob rau hauv kev lag luam luam tsuas yog hnyav raws li cov phom, cov ciav hlau, cov kua nplaum, cov kua roj, cov kua roj vuas, thiab cov dej ntxuav tsheb. Kev lag luam luam VOCs cov nodes yog siv los luam, kev sib txuas, txheej, glazing thiab ci. Qhuav luam ntawv thiab lwm yam dab tsi; luam tawm kev lag luam feem ntau siv offset printing, ua raws li gravure printing, gravure printing tam sim no siv hnyav hauv inks, uas yog lub ntsiab lus ntawm VOCs emissions hauv kev lag luam luam; tam sim no, kev tswj theem ntawm luam cov tuam txhab muaj kev sib txawv, thiab txoj kev kho qhov xaus-ntawm-yeeb nkab chaw yog saws. Tsawg; cov kev luam ntawv ntawm cov luam ntawv luam tawm tsuas yog 20-40% xwb, tab sis NMHC emission concentration ncav cuag 600 mg / m3, thiab cov txheej txheem raug thiab txheej txheem NMHC concentration yuav ncav cuag 3500 mg / m3.
Kev ntsuas abatement
1. Cov khoom noj nyoos thiab cov ntu ntsuab
Cov ntaub ntawv nyoos nrog VOCs cov ntsiab lus tau siv los hloov cov ntaub ntawv nyoos thiab ntu nrog cov VOCs cov ntsiab lus.
2, cov txheej txheem tsim tawm kom huv
Kev Tswj Txheej Txheem: Txhim kho cov txheej txheem teem caij, txo qhov downtime, thiab nquag hloov luam yeeb.
Ink supply: Ib qho nruab nrab ntawm cov xaim npau suav yog siv.
Kev luam hom: cov khoom siv ncaj roj siv tua roj los ntawm cov roj, UV number case, flexo luam tawm ntawm cov lej dej thiab UV number case es tsis txhob siv cov gravure thiab flexo printing siv xaj kua xaj.
Compound: Solvent compounding yog hloov los ntawm solventless compounding.
3. Kev tswj ntau lawm
Luag Cov Sij Hawm Kho: muab cov khawm tshwjxeeb hloov chaw, siv lub hood lub xovtooj thaum lub xauv npo yuav tsum rov kho dua thaum siv tus number case.
Luam tawm: sau tau yooj yim ntawm kev luam ntawv thiab ziab cua tshuab; number case tank thiab number case muab cev raug muab ntim rau hauv tus txheej txheem ntau lawm; txo cov ntaub ntawv luam tawm thiab pov tseg ntau npaum li cas.
Kev Ntxuav Tsheb: siv lub rhaub dej ntxuav, siv tshuaj ntxuav tsheb tsis zoo, thiab yuav tsum tau muab yaug dej yoojyim kom tau ib lub rhiav tshwjxeeb.
Pw ua ke: kev sau los ntawm kev sib txuas thiab ziab kom qis; nplaum lo lub tank kaw lub cua tso pa.
Cov ntaub ntawv teev tseg: Lub chaw ua qoob rau cov VOCs raw lub npe, VOCs cov ntsiab lus, cov nqi yuav, cov nqi siv, thiab cov nqi khoom muag.
