Beddelka Jumlada Birta Catalytic ee Soo Saaraha iyo Alaabta mootada |JSMUFLER

Beddelka Birta Catalytic ee mootada Sawirka leh

Sharaxaad Gaaban:

1. Nooca kicinta: Platinum, palladium, rhodium, iyo biraha kale ee qaaliga ah iyo curiyayaasha dhulka naadirka ah ee kiciya dhismaha.

2. Substrate Kataliye: Substrate dhoobada malabka, substrate bir ah.

3. Daahan heer sare ah oo loogu talagalay waxqabadka catalytic adag, waara oo xasilloon.

4. Tiknoolajiyada horumarsan iyo sidayaal farsamooyinka baakadaha si loo hubiyo shoogga kulaylka la isku halayn karo iyo xasilloonida farsamada.

5. Kala duwanaansho, qeexid dhammaystiran, shuruudaha macaamiisha waxaana laga yaabaa inay ku salaysan yihiin cabbirro farsamo si loo waafajiyo baahiyaha kala duwan ee macmiilka.

6.Waxay la kulmi kartaa Euro3,Euro4,Euro5 ama CARB, heerka EPA.

Beddelaha catalytic waa aaladda sifaynta dibadeed ee ugu muhiimsan ee lagu rakibay nidaamka qiiqa, kaas oo u bedeli kara gaasaska waxyeelada leh sida CO, HC iyo NOx ee gaaska qiiqa u beddela kaarboon laba ogsaydh, biyo iyo nitrogen oo aan waxyeello lahayn iyada oo loo marayo oksaydheynta iyo dhimista.

Kataliyaha saddex-geesoodka ah (TWC) ee mootada si ay u buuxiso EPA, CARB iyo Euro III, IV, V, VI heerka qiiqa.Adigoo isticmaalaya birta chromium aluminium alloy (FeCrAl) jirka malabka sida xambaara, platinum (Pt), palladium (Pd), rhodium (Rh) iyo biraha kale ee qaaliga ah sida qaybaha firfircoon ee firfircoonida.Isticmaalka tikniyoolajiyadda dahaarka gaarka ah si loo hagaajiyo ku-xidhka biraha qaaliga ah ee substrate-ka birta ah, hufnaanta beddelka ee CO, HC iyo NOX waxay gaari kartaa in ka badan 85%, taas oo ka caawin doonta kicinta buuxinta shuruudaha adkeysiga 30000 km.

Ka hor inta aanad galin gaaska VOCs, waa lagama maarmaan in la galo hawo nadiif ah oo qulqulaya si aad si buuxda u diiriso kicinta (kuleylka ilaa 240ºC ~ 350ºC) . marka la buuxiyo, oo si dhow loo dhigo, iyada oo aan lahayn nusqaamo. Heerkulka shaqada ee ugu fiican ee kicinta waa 250 ~ 500ºC, xoogga gaaska qiiqa waa 500 ~ 4000mg / m3, iyo GHSV waa 10000 ~ 20000h-1.Waa in laga fogaadaa inta suurtogalka ah si looga fogaado korodhka degdega ah ee xoogga gaaska qiiqa ama heerkulka sare ee muddada dheer ee kicinta ee ka sarreeya 600ºC. Daroogadu waa inay noqotaa mid aan qoyaan lahayn, ha ku qoolin ama biyo raacin.

Iyada oo loo marayo oksaydhka catalytic ee dhammaan noocyada gaaska wasakhda organic kacsan ee warshadaha VOCs, si loo gaaro heerarka qiiqa warshadaha, inta badan loo isticmaalo daaweynta gubashada catalytic ee cuntada, kiimikada, daabacaadda, mishiinada, soo saarista baabuurta, petrochemical, kiimikooyinka organic, warshadaha kiimikada dawooyinka qiiqa ka kooban carbon monoxide , hydrocarbons caraf udgoon, hydrocarbons iyo oksijiin-ka kooban derivatives, iwm sunta iyo gaaska qashinka organic waxyeello.
