Sistemu na SCR na Kusantarwa: Amsa ta Kammalai Don Kusantarwa na NOx na Sana'ah

Shirye-shirye: Yadda ake bukata ga kula da sautin NOx na ƙarami

Nitrogen oxides (NOx) suna cikin abubuwan da suka sausakar gaskiya na hawa wanda ake samun su ne a lokacin yadda ake soofa daga kuma ake soofa. Su ne da ke zama daga boilers, furnaces, kilns, gas turbines, waste incinerators, da sauran alatun soofa na yara yara. Lokacin da ake baiwa su a tsaki, NOx ke taka muhimmin cin zafi, photochemical smog, da abubuwan hawa wanda suka yi sako ga al’ummar da mutane.

Daga wajen yadda kada kadan na yadda ake nuna kafin kafin da suka ci gaba, al’ummar na soofa suna kawo kafin kafin da suka ci gaba don kuskurenin NOx. Alama na soofa ta farko ba ta iya samun kafin kafin da suka ci gaba ba. Don haka, teknologiyar denitrification na flue gas ta yara yara suna zama muna amfani da su ga al’ummar na power generation, steel production, cement manufacturing, petrochemical processing, da waste-to-energy.

A cikin sauran teknologiyar kontrolin NOx, Reduction a cikin Catalytic (SCR) yana daidai aminciwa ne kamar ɗayan na ƙarfi da ƙarfi na yadda ake amfani da su. Daga wajen ƙarfin fuskantar NOx, tsarin biyayen gaskiya, da tsarin biyayen daga cikin lokaci ta yawa, tsarin SCR ya zama ƙananan abu na yadda ake amfani da su don tsarin biyayen industriya na yadda ake amfani da su don tsarin biyayen gaskiya.

Kamar ƙaramin al'ummar tattalin arziki na yadda ake amfani da su, MirShine Environmental Group ta ba da tsarin SCR na yadda ake amfani da su, tsarin biyayen gaskiya, bayani na abubuwa, da halayen EPC don tabbatar da abubuwan industriya suna samun tsarin biyayen gaskiya da suka tabbatar da yadda ake amfani da su don tsarin biyayen gaskiya.

Wane ne tsarin SCR na yadda ake amfani da su?

SCR (Selective Catalytic Reduction) shi ne tsarin biyayen gaskiya na yadda ake amfani da su wanda ya amfani da abu na yadda ake amfani da su, wanda ke kuma ammonia (NH₃) ko ruwa na ammonia, don yin nitrogen oxides (NOx) a cikin gaskiya na yadda ake amfani da su don yin nitrogen (N₂) da ruwa na yadda ake amfani da su (H₂O).

Wadanda su ne tsarin kimiyar da suke amfani da su:

4NO + 4NH₃ + O₂ → 4N₂ + 6H₂O

6NO₂ + 8NH₃ → 7N₂ + 12H₂O

A cikin lokacin amfani, ammonia ta shigar da gas na kofa ta hanyar sistema na shigar da ammonia. Gas din da aka tsaya suka taka gaban layi na catalyst a cikin reactor na SCR. A lokacin da za a iya yin amfani da su, catalyst ya zama mai sauya yadda ammonia da NOx suka yi amfanin kimya, wanda ya bawa kari mafi kyau na bayanin NOx.

A matsayin da suka fahimci sauran hanyoyin gwado na nitrogen, teknologiya na SCR ta iya samun kari mafi kyau na gwado, wanda ke zama 80–95% gwado na NOx , tare da lokacin amfani, tallafin layi na catalyst, da design na sistema.

Sukunin Gwado na SCR na kasuwa

Sukunin SCR na gwado na nitrogen ta daga kadan abubuwan da suka dace da suka tsaya da suka ci gaba don tabbata da gwado na NOx da kari mafi kyau da tsakanin su.

1. Sistema na Shigar da Ammonia

Sistema na shigar da ammonia ta sanya aiki da kuma ba da ammonia a gas na kofa da kari mafi kyau.

Sukunin da aka raba da ammonia daidai ya tabbata da:

• Kari mafi kyau na shigar da ammonia
• Karamin kudin ammonia
• Karamin kudin ammonia a wani lokaci
• Karamin kudin SCR

Ko ƙarancin ammonia ba ta dace ba, zai iya haɗawa da karamin kudin NOx da karamin kudin bayanin ayyukan. Don haka, rarrabbarin gurbi na ammonia (AIG) ke taka muhimmi ga karamin kudin sistema.

2. Gurbin SCR

Gurbin SCR shine abin da ke taka muhimmi wanda ake yin amfani da shi don karamin NOx.

A cikin gurbin, kudin katalis ke rarrabba a cikin manya manya. Gas na kofin ya tashi a cikin kudin katalis, wanda ke ba da damu don NOx da ammonia su yi amfani da karamin kudin.

Rarrabbarin gurbin SCR yana bukatar fahimta:

• Kudin gas na kofin
• Kudin yaki
• Karamin ƙarfi
• Sakamako na katalis
• Rubutun Rubutu

Don farko na sana’a, tsarin na reactor zai iya canza saboda farko na composition na gas na furnace da shugaban halali.

3. Katalis na SCR

Katalis shine babban abu na sistema na SCR.

Katalis na SCR wanda ake amfani da su sun hada da:

• Katalis na titanium dioxide
• Katalis na vanadium-tungsten-titanium
• Katalis na honeycomb
• Katalis na plate

Amsar da catalyst yana da shi da:

• Kari na yin flue gas
• Karamin dust
• Karamin sulfur
• Matali na alkali
• Karamin matali na gaba

Misali, masu gudunmawa na waste suka yi amfani da gas na flue wanda ke cikin ƙarfi sosai don masu gudunmawa na power plants, wanda suka buƙatar catalysts da ke da kyau karfi don zama resistant against poisoning da deactivation.

4. Nassara na Tsarin

Sisitem na automatic control ya nuna da ya rarrabe amsar SCR, domin:

• Kudin NOx
• Yadda ammonia ta shiga
• Zazzabi
• Kunya ta fofa
• Kudin gas na flue

Sisitem na intelligent control ta taimaka wajen samun tsayi mai ban shi kuma yana rage karamin ammonia da karamin amsa.

Yaya zai sa kari SCR Technology don gudunawa NOx a kasashen sana’a?

1. Yanzu na NOx Removal Efficiency

Wani daga cewa muna da yawa na SCR technology shine karamin gudunawa NOx.

A matsayin SNCR systems, SCR iya gudunawa NOx ta hanyar daidai a wani tsari mai ban shi. Wannan ya sa SCR ya zama mafi kyawawan don sana’oyi da suka neman gudunawa mai ƙarfi.

2. Maimaita don Kasashen Sana’a Mai Tsawo

SCR systems suna amfani da su a:

• Mashefin kudaden kwalli
• Kasashen sana’a na gas
• Tashar shanu
• Mazugun semento
• Mabudin kimiya

• Shuka-shara-zuwa-Makamashi

Wadannan sana’oyi suna bukatar aiki da kuma suka neman gudunawa mai ƙarfi na al’ummar, wanda ke nufi da karamin gudunawa SCR.

3. Karamin bayani na aiki a lokacin da aka yi

Kamar da SCR yana buƙata karamin bayani na farko mai ƙarfi don hanyar wani teknoliji, ya ba dukkan abubuwan da ke takaici a lokacin da aka yi amfani da shi a lokacin da ke ƙarfe.

Sistam SCR da aka tsara suka iya rage:

• Tsarin amoniya da ke ƙarfe
• Yadda ƙananen katalis yana canzawa
• Biyan biyan kiyaye
• Kura na kura na kura na kura
