Nkibice byingenzi bigize sisitemu yogeza gazi ya kijyambere,silicon karbide FGD NozzlesGira uruhare runini mubikorwa byinganda nkimbaraga zumuriro na metallurgie. Iyi silicon carbide ceramic nozzle yakemuye neza ikibazo cya tekinike ya tekiniki gakondo yicyuma cyangirika cyane kandi cyambaye imyenda myinshi hifashishijwe igishushanyo mbonera gishya hamwe niterambere ryibintu, bitezimbere cyane imikorere ya desulfurizasi.
1 properties Ibikoresho bifatika bishyiraho urufatiro rwo gukora
Mohs gukomera kwasilicon carbide ceramicsigera kuri 9.2, icya kabiri nyuma ya diyama, kandi gukomera kwayo kuvunika gukubye inshuro eshatu iy'ubutaka bwa alumina. Iyi covalent kristaliste itanga ibikoresho hamwe no kurwanya abrasion nziza cyane, kandi bitewe ningaruka yihuta yihuta irimo kristu ya gypsumu (umuvuduko ugera kuri 12m / s), igipimo cyo kwambara hejuru ni 1/20 cyicyuma cyizuru. Muri acide-base ihinduranya ibidukikije bifite pH ifite agaciro ka 4-10, igipimo cyo kurwanya ruswa ya karubide ya silicon kiri munsi ya 0.01mm / mwaka, kikaba cyiza cyane kuruta 0.5mm / mwaka wicyuma cya 316L.
Coefficente yo kwagura ubushyuhe bwibikoresho (4.0 × 10 ⁻⁶ / ℃) yegereye icyuma, kandi irashobora gukomeza guhagarara neza muburyo butandukanye bwubushyuhe bwa 150 ℃. Silicon carbide ceramics yateguwe nuburyo bwo gucumura reaction ifite ubucucike burenga 98% hamwe nubushake buri munsi ya 0.5%, bikumira neza ibyangiritse byubatswe biterwa no gucengera hagati.
2 mechanism Uburyo bwiza bwa atomisiyonike no kugenzura imirima
Uwitekasilicon karbide spiral nozzlebyongera cyane umuvuduko wo kuzunguruka wa slurry, kandi hamwe nubuso busobanutse neza, busenya amabuye ya hekimoni mu bitonyanga bito kandi bimwe. Igipimo cya hollow conical spray umurima wagizwe niyi nyubako ni nini cyane, kandi igihe cyo gutura ibitonyanga muminara cyongerewe amasegonda 2-3, hejuru ya 40% ugereranije n’amajwi gakondo.
3 、 Guhuza sisitemu no gutezimbere ubuhanga
Mu munara usanzwe utera,silicon karbide FGD nozzlesitunganijwe muburyo bwa chessboard ikoreshwa, hamwe ninshuro 1,2-1.5 inshuro ya spray cone diameter, ikora ibice 3-5 byuzuye. Iyi gahunda iremeza ko kwambukiranya ibice umunara wa desulfurizasi urenga 200%, bigatuma habaho guhuza bihagije hagati ya gaze ya flux na slurry. Hamwe numuvuduko wubusa wa 3-5 m / s, gutakaza umuvuduko wa sisitemu bigenzurwa murwego rwa 800-1200 Pa.
Imikorere ikora yerekana ko imikorere ya desulfurizasi ya sisitemu ya FGD ikoresheje silicon karbide nozzles ikomeza kuba ihagaze hejuru ya 97.5%, kandi nubushuhe bwibintu bya gypsumu biva mubicuruzwa bigabanuka kugeza munsi ya 10%. Inzira yo gufata neza ibikoresho yongerewe kuva ku mezi 3 ku byuma bigera ku myaka 3, kandi ibiciro byo gusimbuza ibikoresho byagabanutseho 70%.
Ikoreshwa ryibiFGD nozzleIkimenyetso gisimbuka kuva kinini kugeza neza ibikoresho byo kurengera ibidukikije. Hamwe no gukura kwikoranabuhanga rya 3D ryandika ceramic, igishushanyo mbonera cya topologiya cyerekana imiterere yimiyoboro yimigezi irashobora kugerwaho mugihe kizaza, gishobora kurushaho kunoza imikorere ya atomisiyasi 15-20% kandi igateza imbere ikoranabuhanga ryangiza cyane ryinjira mubyiciro bishya byiterambere.
