Ukwandiswa Ilaphu kunye oksijini ukuvuleka Ingxubevange

Oksijini okanye ziyalinganiselwa ioksijini-umsi ukunyibilika (KVP okanye CDF) indlela uhlobo flash autogenous lokunyibilikisa emanzini ubhedu liziphose kuwo, uqhutywe ezingadibaniyo. Ezona mpawu ziphambili zale nkqubo zisetyenziswa ioksijini yobugcisa bevuthela kunye nokutshiswa sulfides plume oxwesileyo kunye nelaphu compensator.

Inkqubo Inco (DPC) ludalwe ngokuyintloko njengendlela yokuvelisa engamanzi sulphur dioxide le yintlama imini nephepha shishino ekusetyenzweni imixutywa sulphide yobhedu. inkqubo Autogenous lokunyibilikisa usebenzisa isikali yorhwebo njenge oxidant kwinkqubo ioksijini ecocekileyo (95% O2) oluqhutywa phaya mveliso 1953 Copper Cliff eKhanada. Inkqubo efanayo yaphuhliswa eSoviet Union kunye ezavela isityalo ngobhedu Almalyk (Uzbekistan). Umahluko eziphambili CFP PVP kukuba kuxubana elinqunqiweyo ngokushiyanayo wome uvelise nzulu ezikweni ngokusebenzisa ngumqolo inkcukacha isamente ngqo tye (nkqo shaft kweintanethi yokunyibilika) kwaye usebenzisa ioksijini olunyulu njengoko inkqubo oxidative udubulo. inkqubo lokunyibilikisa lwenziwa ukufumana matte 45-55% (xa ezifumana matte likwabhekisela ngenxa anxile eziko ubushushu overheats). Ezi gesi inkunkuma anokuqulatha ukuya kwi-80% SO2. Nethemba ebanzi inkqubo yesicelo mveliso iye Inco.

Ezona mpawu zibalulekileyo zobugcisa CFP zezi: ubukho kwi ezikweni ilangatye oxwesileyo kwandisa ixesha yokuhlala amasuntswana esikuso, kufuneka ngokwenkcazo ukukhuthaza amasuntswana ukugxininiswa igcwala iinkqubo ibhetshi ukuqhubekekiswa, kwakunye lokushushubeza inyama compensators; ithuba eliqingqiweyo olawula iqondo desulfurization bejonge indyebo yalo, nakwenzeka yokufumana matte ezinomthamo yobhedu 65-70% ngenxa yokumpompoza kulo mzekelo isixa esikhulu ubushushu obugqithisileyo nokuvusa ubushushu ezikweni ukuya 1550-1600 ° C, yaye ngaphezulu, kwabanomtsalane kunciphisa kweelana ababedume eliyinjubaqa; nakwenzeka ngenxa yezizathu ezifanayo ukwanda okubonakalayo izinga imveliso eziko ukunyibilikisa; umthamo ezincinane ezifunyenwe ngexesha ndiyabanyibilikisa iigesi sulphur-sisityebi, isiqulatho theoretical component SO2 owawufikelela 90-95%. Xa CFP zisebenziseke pulverulent mxube yaziswa etshayo isithuba kwiziko zobugcisa oxygen jet evela Kompenz Elastic, nto leyo ekhokelela kuseko uthuli negesi plume, apho izinto oxidized linyibilike. Inkqubo lokusekwa kunyibilika ezikweni bath delaminated ukuba matte kunye zeBlack. Jonga omisiweyo tofo iphaphatheke umxube kunye fluxes jet tye ezikhule sokukhuphela ekhethekileyo idangatye ezikweni. unxibelelwano Physico-chemical phakathi amacandelo umthwalo uthule ioksijini flow kwi ukugeleza eluthulini. Amathontsi ezifakwe ukusuka zokunyibilikiswa plume emazantsi eziko kwaye enze nebhate ulwelo.

Ezi nkalo zilandelayo esekwe kwi CFP eziko:

- ntlawulo-oksijini letotshi, apho igcwala of sulphide kwenzeka ngokuyinxenye kunye neenkqubo slagging shteyno- (I);

- zeBlack bath komhlaba, apho wobhobhozayo kunye abasabela ekugqibeleni zifunxe of impefumlelwano sulfides kunye oxides (II);

- Stein-SLAG bath, apho inkqubo ulwenze kunye shteyno- slagging (II, III).

- ngelaphu ukwanda amalungu

CFP ezikweni isigxina equka mxube yobhedu zwi. Lo mxube ke ecociweyo, kunye isiqulatho sokufuma 12-16% in kwigubu womisa ukuya yoxinaniso ntsalela ka-4-7%, ngelixa ngokusebenzisa compensators. Inyathelo yokomisa yesibini oluqhutywa umbhobho wokomisa nkqo, inxalenye esezantsi leyo isebenza iigesi ashushu, ndinobushushu 400-500 C ngereyithi eyi-12-14 m / s. ukufuma lokugqibela ka 0.1-0.5%, mxube yokusebenza notsala yi 80-85 m / hr, yi ukufuma eshukumayo ku-4 t / h.

Isantya esiphakamileyo iinkqubo oxidative Isigaba umlinganiselo zoqhagamshelwano umphezulu, nzima olo hlengahlengiso kunye nokwakheka thermal matte kunyityilikiswa mode. Ukulungiselela Iziphumo matte likwabhekisela ekubunjweni ubushushu obugqithisileyo kunye oonobangela ukunxiba yethemba. Kuba ulawulo emhlabeni inkqubo kule meko kuyimfuneko ukunciphisa umthamo yunithi lo mxube. Ukunyusa akhande uxhathiso kessoniruyut arch kunye nodonga neziko kusetyenzwa eziphathekayo (uthuli, Converter zeBlack) ajikelezayo, oko kuza komeleza isiqulatho yobhedu le matte ngaphandle ukwanda koxinzelelo thermal ebandleni kunye compensators zeethishu.

CFP ezikweni amaziko ezenziwe ngezitena kunye compensators hromomagnezitovogo Kompenz-Elastic. Irhasi ezikweni ngalo ulwelo embindini iyunithi isithuba yokutsha. Njengoko inkqubo kuvuthela ioksijini lisetyenziswa ezinomthamo ka 95-98 vol. %. Stein, equlethe 40-50% ubhedu, i lukhutshwa ezinemingxuma emele amanzi. SLAG obegalelwe ngalo taphole kwi SLAG, kwaye ithunyelwe lwenkunkuma. iigesi Iziko lesinyithi nothuli ngokusebenzisa uqhagamshelwano ngqo ezibandayo igesi flue. Ukususwa uthuli malunga ne-10% ngokobunzima mxube. iigesi Uthuli 300-400 g / m≥ nghena kwibhoyila ukuchacha kwaye ngamashishini yayo - 200-250 g / m≥.

CFP nayo zisetyenziswe ngempumelelo xa kusingathwa Cu-Zn-, Cu-Ni- et al. Sulphide lithi ligxininise khona.
