Njengenxalenye engundoqo yeenkqubo zanamhlanje zokucoca igesi yombane,i-silicon carbide FGD Imibhobhoidlala indima ebalulekileyo kwiinkalo zoshishino ezifana namandla obushushu kunye nesinyithi. Lo mbhobho we-silicon carbide ceramic sombulula ngempumelelo ibhotile yobugcisa bemilomo yentsimbi yesiko phantsi komhlwa owomeleleyo kunye neemeko zokunxiba okuphezulu ngoyilo oluyilayo lolwakhiwo kunye nokuphumelela kwezinto eziphathekayo, kuphucula kakhulu ukusebenza kakuhle kwe-desulfurization.
I-1, Iimpawu zezinto eziphathekayo zibeka isiseko sokusebenza
Ubunzima beMohsi-silicon carbide ceramicsifikelela kwi-9.2, okwesibini kuphela kwidayimane, kwaye ukuqhawuka kokuqina kwayo kuphindwe kathathu kunoko kwe-alumina ceramics. Esi sakhiwo sekristale esine-covalent sinika izinto eziphathekayo ezinokumelana nokutshatyalaliswa kwe-abrasion, kwaye phantsi kweempembelelo ze-slurry ezikhawulezayo ezineekristale ze-gypsum (izinga lokuhamba ukuya kwi-12m / s), izinga lokunxiba lingaphezulu kwe-1/20 kuphela ye-nozzles zetsimbi. Kwi-acid-base alternating environment kunye nexabiso le-pH ye-4-10, izinga lokumelana nokubola kwe-silicon carbide lingaphantsi kwe-0.01mm / ngonyaka, elingcono kakhulu kune-0.5mm / ngonyaka we-316L yensimbi engenasici.
I-coefficient yokwandisa i-thermal yezinto eziphathekayo (4.0 × 10 ⁻⁶ / ℃) isondele kwintsimbi, kwaye isenokugcina ukuzinza kwesakhiwo phantsi komlinganiselo weqondo lokushisa kwe-150 ℃. I-Silicon carbide ceramics elungiselelwe yinkqubo ye-reaction sintering inobuninzi obungaphezu kwe-98% kunye ne-porosity engaphantsi kwe-0.5%, ikhusela ngokufanelekileyo umonakalo wesakhiwo obangelwa ukungena okuphakathi.
I-2, indlela ye-atomization echanekileyo kunye nolawulo lwentsimi yokuhamba
Ii-silicon carbide spiral nozzlekwandisa kakhulu isantya esijikelezayo sodaka, kunye ne-outlet aperture echanekileyo, iqhekeza i-limestone slurry ibe ngamathontsi amancinci kunye afanayo. Umngxuma conical isitshizi isigqubuthelo intsimi inqanaba eyenziwe kwesi sakhiwo likhulu kakhulu, kwaye ixesha lokuhlala amathontsi kwinqaba yandisiwe ukuya kwimizuzwana 2-3, 40% ngaphezulu kunombhobho zemveli.
3. Ukuhambelana kwenkqubo kunye nokwenza ngcono ubunjineli
Kwinqaba yokutshiza eqhelekileyo,imilomo ye-silicon carbide FGDzicwangciswe ngendlela chessboard zisetyenziswa, kunye izithuba 1.2-1.5 amaxesha isitshizi cone ububanzi, ukwenza 3-5 umaleko yokwaleka. Eli lungiselelo liqinisekisa ukuba i-cross-sectional coverage ye-desulfurization tower idlula i-200%, iqinisekisa uqhagamshelwano olwaneleyo phakathi kwe-flue gas kunye ne-slurry. Ngomlinganiselo wokuhamba kwenqaba engenanto ye-3-5 m / s, ilahleko yoxinzelelo lwenkqubo ilawulwa ngaphakathi kwinqanaba le-800-1200 Pa.
Idatha yokusebenza ibonisa ukuba ukusebenza kwe-desulfurization yenkqubo ye-FGD usebenzisa i-silicon carbide nozzles ihlala izinzile ngaphezu kwe-97.5%, kwaye umxholo wokufuma we-gypsum by-products uyancipha ukuya ngaphantsi kwe-10%. Umjikelo wokugcinwa kwezixhobo uye wandiswa ukusuka kwiinyanga ezi-3 kwimibhobho yentsimbi ukuya kwiminyaka emi-3, kwaye iindleko zokutshintshwa kwezinto ezisetyenzisiweyo ziye zehla nge-70%.
Ukusetyenziswa kokuFGD umbhobhoIphawula umtsi ukusuka kwisixhobo esibanzi ukuya kwezona zichanekileyo zokhuselo lokusingqongileyo. Ngokukhula kwetekhnoloji ye-ceramic yoshicilelo lwe-3D, uyilo lokuphucula i-topology yolwakhiwo lomjelo wokuhamba lunokuphunyezwa kwixesha elizayo, elinokuphucula ngakumbi ukusebenza kakuhle kwe-atomization nge-15-20% kunye nokukhuthaza itekhnoloji yokukhutshwa kwe-ultra-low ukungena kwinqanaba elitsha lophuhliso.
