Ityala |Zisetyenziswa njani izivutheli ze-oyile ezingenawo-oyile kunye nezivutheli ze-centrifugal ukulungiselela inguqu eyonga amandla kushishino lwesamente?
Itekhnoloji ye-SCR denitrification, oko kukuthi, indlela yokunciphisa i-catalytic ekhethiweyo, igesi ye-ammonia ifafazwe kwisixhobo sobushushu obuphezulu se-flue flue denitrification njenge-arhente ye-denitrification.Ngaphantsi kwesenzo se-catalyst, i-NOx kwi-flue gas ichithwa kwi-non-toxic and pollution-free N₂ kunye ne-H₂O.Kwisixhobo sebhoyili esisebenzayo se-SCR, izinga lokukhutshwa kwe-denitrification lifikelela kuma-80-90%, kwaye ukuphuncuka kwe-ammonia kungaphantsi kwe-3 mg/Nm³, nto leyo ehambelana kakhulu neemfuno eziphezulu zokuchaneka kwe-denitrification yezityalo zesamente.
① I-ammonia yolwelo ithunyelwa ukusuka kwilori yetanki ye-ammonia yolwelo ukuya kwitanki yokugcina ye-ammonia ngolwelo lwecompressor
②Emva kokuphuma ngumphunga kwi-ammonia kwitanki yokuqhuma, ingena kwindawo yebhoyila ngetanki yesithinteli se-ammonia kunye nombhobho wokuthutha.
③Emva kokuxutywa ngokulinganayo nomoya, ingena kwi-reactor ye-SCR ngokusebenzisa ivalve yokulinga yokusabela kwangaphakathi.I-reactor ye-SCR ifakwe phambi kwe-air preheater, kwaye igesi ye-ammonia ingaphezulu kwe-reactor ye-SCR.
④Xuba umsi ngokulinganayo ngesixhobo sokutshiza esikhethekileyo
⑤Emva kokuxuba, i-flue gas idlula kwi-catalyst layer kwi-reactor yokunciphisa ukusabela.
Itekhnoloji yokuvuthela i-air compressor air soot
Xa ukhetha indlela yokuvuthela i-soot, ukongeza kwisiphumo sokuvuthela umsizi, isiphumo sokunxiba kwi-catalyst kufuneka siqwalaselwe.Okwangoku, iindlela zokuvuthela i-soot eziqhele ukusetyenziswa kwiinkqubo ze-SCR denitration zibandakanya ukuvuthelwa kwe-soot, ukuvuthuza kwe-soot yomphunga kunye nokuvuthelwa komoya.
Idityaniswe neempawu zomsi we-sement kiln kunye nothuli, kunzima kwii-sonic blowers zesoot ukuziqhelanisa nesixa esikhulu kunye ne-viscosity ephezulu ye-cement kiln flue gas dust.Ukongeza, imveliso yegesi yomphunga kwiplanti yesamente incinci, ngoko ke kufanelekile ukusebenzisa umoya oxinanisiweyo ukuvuthela umle.
Kwiminyaka yakutshanje, ngokuphuculwa kunye nophuhliso lweshishini lesamente kwindawo yokhuseleko lokusingqongileyo, imigangatho yokukhupha iye yanyuswa kakhulu.Ukuthintela kunye nokulawulwa kokungcoliseka komoya kunye nokunciphisa ukukhutshwa kwegesi ye-nitrogen oxide kuye kwaba yimisebenzi engxamisekileyo ejongene namashishini emveliso yesamente.Itekhnoloji ye-SCR (Catalytic Reduction) inokusebenza kakuhle kwe-denitrification kwaye inokufikelela kwi-ultra-low emissions ye-flue gas nitrogen oxides kunye nokuphunyuka kwe-ammonia phantsi kwemeko yokusetyenziswa kwe-ammonia ephantsi.Kwiminyaka yakutshanje, itekhnoloji ye-samente yegesi ye-samente ye-SCR nayo yenze inkqubela phambili, ibonelela ngesiqinisekiso esisebenzayo kwiinkampani zesamente ukuphumeza ukukhutshwa kwe-ultra-low.
