Ⅰ. Mfundo yofunika

SO2 ndi chimodzi mwa zikuluzikulu zoipitsa mpweya ndi chizindikiro chofunika ulamuliro wa mafakitale zinyalala kuipitsidwa kwa mpweya ku China. Pakadali pano, makina onse opangira malasha ku China agwiritsa ntchito mapulojekiti ochotsa mpweya wa flue, pomwe ukadaulo wapamwamba wa desulfurization ndi limestone/gypsum wet flue gas desulfurization (WFGD). Pochita izi, matope a miyala yamchere amagwiritsidwa ntchito ngati choyatsira, chomwe chimagwirizana ndi mpweya wa flue mu nsanja ya desulfurization ndiyeno imasakanikirana. Pambuyo SO2 mu gasi chitoliro amachitira ndi kuyamwa, ndi mankhwala amachitira ndi mpweya oxidizing kuti kuwomberedwa ndi oxidizing zimakupiza kupanga gypsum.

Pali thanki ya slurry pansi pa nsanja yoyamwitsa, ndipo chotsitsa chatsopano chimaponyedwa mu thanki ya slurry kudzera pampopi ya miyala yamchere yodyetsera slurry; pansi pa ntchito ya agitator, imasakanizidwa ndi slurry yomwe ilipo mu thanki ya slurry; ndiye, slurry kuzungulira mpope adzakweza slurry wosanganiza kwa wosanjikiza kutsitsi ndi utsi pansi kukhudzana ndi mpweya chitoliro mu potsimikizira-panopa otaya. Kubwezeretsanso kwanthawi yake kwa zotumphukira zatsopano ndikofunikira munthawi yonseyi. Ngati ndalama zowonjezera sizikwanira, zimakhala zovuta kutsimikizira kuti desulfurization ikugwira ntchito bwino; ngati ndalama zowonjezerazo ndi zochuluka kwambiri, zidzachepetsa kugwiritsa ntchito mphamvu zoyamwa, komanso zimakhudza ubwino wa mankhwala a desulfurization. Chifukwa chake, kuwongolera pampu ya miyala yamchere ndi gawo lofunikira pakugwira ntchito kwa FGD.

Ⅱ. Mapampu ofunikira ndi makina opangira

1. Njira yokonzekera miyala yamchere

2. Pampu kwa dongosolo mayamwidwe nsanja

3. Dongosolo la mpweya wa flue

4. Pampu ya gypsum dewatering system

5. Mapampu a machitidwe otulutsa

6. Mapampu a machitidwe opangira madzi oyipa

Kupatula makina opangira gasi, machitidwe omwe ali pamwambawa adzafuna mapampu amatope. Mu dongosolo la mayamwidwe a nsanja, voliyumu ya jakisoni ndi yayikulu, kotero kuti m'mimba mwake wa mpope ndi wamkulu. Mapampu omwe ali mu gawoli ndi mapampu apadera apadera opangira desulfurization, ndipo mapampu omwe amagwiritsidwa ntchito muzinthu zina ndi mapampu athu omwe amagwiritsidwa ntchito kawirikawiri ang'onoang'ono ndi apakatikati. Malinga ndi momwe slurry imakhalira, zinthu zomwe zasankhidwa pazigawo zoyenda sizimva kuvala komanso zosachita dzimbiri.

Chithunzi cha FGD System

Pampu yozungulira ya FGD system yomwe ikugwiritsidwa ntchito pa Site
