Wanaajinta Ilaalinta Deegaanka: Siidaynta Awooda Nidaamyada Naafaynta Gaaska Daaqaya ee Firfircoon

sawirka 1Desulfurization Tower

The nidaamka desulfurization gaaska qiiqa waa qalab muhiim ah oo loo isticmaalo in lagu dhimo waxa ku jira sulfur dioxide (SO2) ee ku jira gaaska flue. Mabda'iisa shaqo iyo kala duwanaanshihiisa codsigu waa ballaadhan yahay.

Kuwa soo socdaa waa hordhac faahfaahsan oo ku saabsan qiiqa Desulfurization gaaska nidaamka:

1.Mabda'a shaqada

Mabda'a shaqada ee nidaamka desulfurization gaaska qiiqa waxaa inta badan loo qaybiyaa desulfurization qoyan iyo desulfurization qalalan:

Bacriminta qoyan:Desulfurization-ka qoyan waa mid ka mid ah tignoolajiyada nadiifinta ee inta badan la isticmaalo. Habka desulfurization qoyan, xalalka alkaline sida slurry limestone ama sodium hydroxide ayaa inta badan loo isticmaalaa sidii nuugista. Marka gaaska qiiqa uu dhex maro munaaradda desulfurization, waxaa si buuxda loola xiriiriyaa ceeryaamo biyaha ama xalalka alkaline ee laga buufiyay lakabka buufinta. sulfur dioxide ee ku jira gaaska qiiqa waxaa nuuga nuugista oo ka falcelisa kiimiko ahaan si ay u sameeyaan sulfates (sida calcium sulfite ama calcium sulfate). Ka dib, sulfates-yadan ayaa laga yaabaa in si dheeraad ah loo farsameeyo, sida oksaydhka, crystallization, iwm, si loo sameeyo alaabada sida gypsum.

Bacriminta qallalan:Desulfurization qalalan ma isticmaalo biyo ama xal, laakiin waxay isticmaashaa nuugista qalalan (sida kaarboonka firfircoon, calcium oxide, iwm.) si ay ugu dhejiso sulfur dioxide gaaska flue. Habkani wuxuu caadi ahaan ku habboon yahay waqtiyada biyaha ku jira gaaska qiiqa ay yar yihiin ama loo baahan yahay in laga fogaado biyaha wasakhda ah.

2.System ka kooban

Nadaamka wasakhaynta gaaska qashinka sida caadiga ah waxaa ku jira qaybaha ugu muhiimsan ee soo socda:

Nidaamka gaaska hargabka: Waxay ka kooban tahay albaabka dambarka gaaska flue flue albaabka, bypass qiiqa gaaska damper albaabka, qiiqa birta, iwm, kaas oo ka mas'uul ah soo gelinta gaaska flue ka kooban sulfur dioxide galay nidaamka desulfurization.

Nidaamka diyaarinta nuugista (habka qoyan): Sida habka diyaarinta dareeraha nuuradda, oo ay ku jiraan silo budada nuuradda ah, hopper gariiraya, qalabka miisaamaya, feederiyaha fur, mashiinka diyaarinta slurry, iwm, loo isticmaalo in lagu diyaariyo nuugista looga baahan yahay desulfurization.

munaaradda nadiifinta: munaaradda desulfurization waa qalabka asaasiga ah ee nidaamka desulfurization. Gaaska qiiqa wuxuu uga falceliyaa kiimikaad leh nuugista munaaradda si loo gaaro saamaynta desulfurization. Munaaradda desulfurization-ka qoyan waxaa badanaa lagu qalabeeyaa lakab buufin ah iyo lakab wax lagu duubo si loo hagaajiyo waxtarka nadiifinta.

Habka fuuq-baxa ee gypsum (habka qoyan):Alaabooyinka sida gypsum-ka ee ay soo saarto nadiifinta qoyan, daawaynta fuuqbaxa ayaa looga baahan yahay ka faa'iidaysiga ama tuurista ku xigta.

Nidaamka injineernimada dadweynaha: Oo ay ku jiraan nidaamka biyaha habka, nidaamka qaybinta awoodda korantada hoose iyo nidaamka hawada cadaadisay, iwm, si ay u bixiyaan shuruudaha lagama maarmaanka ah ee nidaamka desulfurization.

Nidaamka La Socodka Sii-Deynta Gaaska Ducooyinka Joogta ah (CEMS):loo isticmaalo in lagu cabbiro xuduudaha gaaska qiiqa ee aaladda desulfurization-ka waqtiga dhabta ah, bixinta xogta hagaajinta xuduudaha hawlgalka ee aaladda desulfurization, hubiso hawlgalka caadiga ah ee qalabka, iyo bixinta xogta qiimaynta waxqabadka qalabka desulfurization.

3.Baaxadda Codsiga

The nidaamka desulfurization gaaska qiiqa waxaa si weyn loo isticmaalaa in beeraha warshadaha kala duwan, gaar ahaan kuwa warshadaha u baahan xaddi badan oo falcelinta kiimikada iyo soo saaro gaaska flue ka kooban sulfur dioxide, sida petrochemicals, saliid sifaynta, metallurgy, bacriminta kiimikada, birta, korontada, iwm In warshadaha korontada, nidaamka desulfurization ah waxaa si weyn loo isticmaalaa in tamarta dhuxusha-shiday, tamarta nukliyeerka iyo hababka kale ee tamarta gaaska si loo yareeyo qiiqa deegaanka.

4.Faa'iidooyinka Farsamada

The nidaamka desulfurization gaaska qiiqa waxay leedahay faa'iidooyin farsamo oo badan, oo ay ku jiraan hufnaanta sare ee sulfurization, qaabka hawlgalka dabacsan, ku habboonaanta ballaaran, iyo alaabooyinka deegaanka saaxiibtinimo leh. Intaa waxaa dheer, iyada oo horumarinta joogtada ah ee tignoolajiyada, nidaamka desulfurization gaaska qashinka si joogto ah ayaa loo wanaajiyaa oo loo hagaajiyaa si loo hagaajiyo hufnaanta desulfurization, la yareeyo kharashka hawlgalka iyo in la yareeyo saameynta deegaanka.

sawirka 10 Qalabka nadiifinta gaaska qashinka

Marka la soo koobo, nidaamka desulfurization gaaska qashinka waa qalab muhiim ah oo ilaalinta deegaanka, taas oo muhiimad weyn u leh yaraynta maadada sulfur dioxide ee qiiqa warshadaha iyo ilaalinta deegaanka iyo caafimaadka aadanaha.
