Ⅰ. Isimiso
I-SO2 ingenye yezinto ezingcolisa umoya eziyinhloko futhi iyinkomba ebalulekile yokulawula ukungcoliswa kwegesi yemfucuza yezimboni eChina. Njengamanje, wonke amayunithi emishini esebenza ngamalahle e-China asebenzise amaphrojekthi okukhipha igesi e-flue, phakathi kwawo ubuchwepheshe obuvelele be-desulfurization i-limestone/gypsum wet flue gas desulfurization (WFGD). Kule nqubo, i-limestone slurry isetshenziswa njenge-absorbent, ethintana ngokuphambene ne-flue gas embhoshongweni we-desulfurization bese ihlanganiswa ngokugcwele. Ngemuva kokuthi i-SO2 kugesi we-flue isabela nokumunca, isabela ngokwekhemikhali ngomoya oxidizing oshaywa isiphephetha-moya se-oxidizing ukwenza i-gypsum.
Kunethangi elinodaka ezansi kombhoshongo wokumunca, futhi okumunca okusha kuphonswa ethangini le-slurry ngokusebenzisa i-limestone feeding slurry pump; ngaphansi komsebenzi we-agitator, ixubene ne-slurry ekhona ku-slurry tank; khona-ke, iphampu ejikelezayo e-slurry izophakamisa udaka oluxubile kungqimba lwesifutho futhi lufuthwe phansi ukuze luthintane ne-flue gas ekugelezeni kwamanje. Ukugcwaliswa okusebenzayo nokufika ngesikhathi kwe-absorption entsha kubalulekile kuyo yonke inqubo. Uma inani elingeziwe linganele, kunzima ukuqinisekisa ukusebenza kahle kwe-desulfurization; uma inani elingeziwe liphezulu kakhulu, lizonciphisa izinga lokusebenzisa okumuncayo, futhi lithinte ikhwalithi yemikhiqizo ephuma nge-desulfurization. Ngakho-ke, ukulawulwa kwepompo ye-limestone slurry kuyingxenye ebalulekile yokusebenza kwe-FGD.
Ⅱ. Amaphampu adingwa uhlelo lokucubungula
1. Uhlelo lokulungiselela i-limestone
2. Iphampu yesistimu yombhoshongo wokumunca
3. I-flue gas system
4. Iphampu ye-gypsum dewatering system
5. Amaphampu wezinhlelo zokukhipha
6. Amaphampu wezinhlelo zokuhlanza amanzi angcolile
Ngaphandle kwesistimu yegesi ye-flue, amasistimu angenhla azodinga amaphampu anodaka. Ohlelweni lombhoshongo wokumuncwa, umthamo womjovo mkhulu uma kuqhathaniswa, ngakho ububanzi bepompo bukhulu kakhulu. Amaphampu akule ngxenye amaphampu akhethekile amakhulu aklanyelwe i-desulfurization, futhi amaphampu asetshenziswa kwezinye izinhlelo amaphampu ethu avame ukusetshenziswa amancane naphakathi nendawo. Ngokwesimo se-slurry, into ekhethiwe yezingxenye zokugeleza kokubili ukumelana nokuguga futhi ukumelana nokugqwala.
Umdwebo we-FGD System
Iphampu ejikelezayo yohlelo lwe-FGD esetshenziswa eSizeni
