Faa'iidada VOC ee kicinta birta sharafta leh
a) Codsi ballaadhan.Qalabka VOC ee leh birta sharafta leh ayaa si weyn loo isticmaalaa, sida buufinta, daabacaadda, caagagga la xoojiyay ee fiber-ka, rinjiga UV, farmashiyaha, kiimikaad, kiimikaad batroolka, codsiyada warshadaha gaaska qiiqa silig leh.Halabuurka gaaska qashinka ee warshadaha daabacaadda waa mid fudud, qaybaha ugu muhiimsanna waxaa ka mid ah taxanaha benzene, esters, alcohols, ketones iyo wixii la mid ah.
b) Waxtarka daaweynta sare, ma jirto wasakh labaad.Heerka nadiifinta gaaska wasakhda dabiiciga ah ee lagu daweeyay habka gubashada catalytic ayaa guud ahaan ka sarreeya 95%, iyo badeecada ugu dambeysa waa mid aan dhib lahayn CO2 iyo H2O, markaa ma jirto dhibaato wasakh ah oo labaad.Intaa waxaa dheer, heerkulka hooseeya awgeed, jiilka NOx si weyn ayaa loo dhimi karaa.
Raridda, Baakadaha iyo kaydinta
a) Xintan waxay keeni kartaa kicinta VOC oo leh bir sharaf leh oo ka hooseysa 5000kgs 7 maalmood gudahood.
b) Baakadaha: sanduuqa kartoonka
c) Ku rid weel hawo-mareen ah, ka ilaali xidhiidhka hawada, si aanay u xumaan
Codsiyada kicinta VOC ee leh birta sharafta leh
VOC kicinta biraha sharafta leh waxaa si weyn loogu isticmaalaa beeraha warshadaha soo socda: petrochemical, kiimikaad, buufin, daabacaadda, daahan, silig dhaldhalaalka, steel midabka, warshadaha caag, iwm.
Odhaah
- Inta lagu jiro habka falcelinta gubashada catalytic, ogsijiin ku filan waa in la dammaanad qaadaa si ay uga jawaabto VOCs.Marka ogsijiinku ku filnaado, waxtarka nadiifinta gaaska qashinka ayaa si toos ah u saameyn doona, taasoo keentay in kaarboon madow iyo alaabooyin kale oo ku xiran dusha sare ee kicinta, taasoo keentay firfircooni-qaadid.
-Gaaska wasakhda ah waa in aanu ku jirin baaruud, fosfooraska, arsenic, rasaas, meerkuri, halogens (fluorine, chlorine, bromine, iodine, astatine), biraha culus, xabagta, barta karsanaysa, polymers viscosity sare iyo walxo kale oo kiimiko ah oo sun ah ama walxo.
- Kataliyaha waa in si tartiib ah loo maareeyaa, jihada daloolku waa in uu ahaado mid la jaan qaadaya jihada hawadu u socoto marka la buuxinayo, oo si dhow loo dhigo, iyada oo aan lahayn nusqaan.
Kahor inta aan la galin gaaska VOCs, waxaa lagama maarmaan ah in la galo hawo cusub oo socota si si buuxda loogu sii kululeeyo kicinta (kuleylka ilaa 240 ℃ ~ 350 ℃, oo loo dejiyay heerkulka ugu sarreeya ee loo baahan yahay gaaska ugu adag ee qaybta gaaska qiiqa).
Heerkulka shaqada ee ugu fiican ee kicinta waa 250 ~ 500 ℃, fiirsashada gaasta qiiqa waa 500 ~ 4000mg / m3, iyo GHSV waa 10000 ~ 20000h-1.Waa in laga fogaado inta suurtogalka ah si looga fogaado korodhka degdega ah ee xoogga gaaska qiiqa ama heerkulka muddada dheer ee sare ee kicinta ee ka sarreeya 600 ℃.
- Dhamaadka hawlgalka, marka hore goo goo isha gaaska VOCs, isticmaal hawo nadiif ah si aad u sii wadato kuleyliyaha 20 daqiiqo ka dibna dami qalabka gubanaya.Ka fogaanshaha kicinta xidhiidhka heerkul hooseeya ee gaasta VOCs, waxay si wax ku ool ah u dheerayn kartaa nolosha adeegga kicinta.
- Waxa ku jira boodhka gaaska qiiqa waa in aanu ka badnayn 10mg/m3, haddii kale way fududahay in la xidho kanaalka kicinta.Haddii ay adag tahay in la yareeyo boodhka si loo yareeyo daweynta ka hor, waxaa lagula talinayaa in si joogto ah looga saaro kicinta oo lagu afuufo qoryaha hawada ka hor intaan la isticmaalin, iyada oo aan lagu dhaqin biyo ama wax dareere ah.
- Marka qalab-qaadiyaha la isticmaalo muddo dheer, waxaa jira xoogaa hoos u dhac ah oo dhaqdhaqaaqa ah, sariirta catalytic waa la bedeli karaa ka hor iyo ka dib ama kor iyo hoos, ama heerkulka hawlgalka qolka catalytic si habboon ayaa loo kordhin karaa.
- Marka heerkulka foornada catalytic uu ka sarreeyo 450 ℃, waxaa lagu talinayaa in la bilaabo marawaxada qaboojinta dheeriga ah oo aad buuxiso hawo qabow si aad u qaboojiso foornada kicinta si aad u ilaaliso kicinta.
- Kataliyuhu waa inuu noqdaa mid aan qoyaanka ilaalinayn, ha ku qooqin, biyona ha raacin.
