Parizvino, kumanikidzwa kwekuchengetedza zvakatipoteredza kwefekitari yekugadzira simbi yechoto inotenderera kwakakura. Pakati pavo, sisitimu yekubvisa guruva yegesi yechoto inotenderera ndiyo inonyanya kukosheswa, uye zvakakosha kuita shanduko yakachena kuti pave nekubuda kwemhepo kwakaderera zvakanyanya. Nokudaro, kusarudzwa nekushandiswa kwetekinoroji yekubvisa dust yechoto inotenderera inoshanda, yakachengeteka uye isingadhuri yave nyaya inokosha kumabhizinesi esimbi nesimbi.
Nzira yekunyorova uye nzira yekuomesa yekutenderedza gasi rinoyerera muchoto ine zvayakanakira zvayo.
Tekinoroji yekubvisa hupfu hwemvura muchoto chinotenderera yakapfupikiswa seOG. OG ipfupiso yeOxygen roting furnace Gas Recovery muchirungu, zvinoreva kuti oxygen roting furnace gas recovery. Furnace inotenderera inoshandisa tekinoroji yeOG inogadzira huwandu hwakawanda hweCO flue gas inodziya zvakanyanya uye ine concentration yakawanda muchoto nekuda kwekuita kwe oxidation panguva yekufefetera. Gsi reflue rinodzvinyirira kupinda kwemhepo yakakomberedza kuburikidza nekusimudza siketi uye kudzora kumanikidzwa kwe flue gas mukati mehood. Kana isina kupiswa, tekinoroji iyi inoshandisa vaporization cooling flue kuti itonhodze flue gas, uye mushure mekucheneswa neVenturi tube dust collector ine matanho maviri, inopinda mugasi rekudzoreredza nekuburitsa gas.
Tekinoroji yekubvisa guruva rakaoma muchoto inotenderera inopfupikiswa seLT. IyoLTNzira iyi yakagadzirwa pamwe chete naLurgi naThyssen kuGermany.LTndiyo chidimbu chemazita emakambani maviri aya. Iyi tekinoroji inoshandisa vaporization cooler kutonhodza flue gas, uye mushure mekucheneswa ne cylindrical dry electrostatic precipitator, inopinda mugasi rekudzoreredza nekuburitsa gasi. Mutemo uyu wakatanga kushandiswa mumapurojekiti ekudzoreredza gasi muna 1981.
Tekinoroji yekubvisa guruva remuchoto unotenderera ine mari yakawanda inoiswa kamwe chete, chimiro chakaoma, zvinhu zvakawanda zvinoshandiswa, uye kuoma kwehunyanzvi. Mwero wekusimudzirwa kwemusika munyika yangu uri pasi pe20%. Uyezve, tekinoroji yekubvisa guruva rakaoma inoshandisa mvura yakawanda yakaoma kubvisa guruva remuchoto rinotenderera rinotenderera. Muunganidzi weguruva uri nyore kuunganidza guruva uye kubudiswa kweguruva hakuna kugadzikana.
Kana tichienzanisa nemaitiro ekubvisa guruva rakaoma, maitiro ekubvisa guruva rakanyorova eOG ane chimiro chiri nyore, mutengo wakaderera, uye kushanda zvakanaka kwekuchenesa, asi ane zvazvakaipira zvakaita sekushandiswa kwesimba rakawanda, kushandiswa kwemvura yakawanda, kugadziriswa kwetsvina yakaoma, uye mari yakawanda yekushandisa. Uyezve, tekinoroji yekubvisa guruva rakanyorova inosuka guruva rese mumvura pasinei nehukuru hwezvidimbu, zvichikonzera huwandu hwakawanda hwetsvina yekubvisa guruva. Kunyangwe huwandu hwehunyanzvi hwemaitiro ekubvisa guruva rakaoma uye rakanyorova hwave huchivandudzwa nguva dzose mukuita kwenzvimbo, zvikanganiso zvavo zvepanyika hazvina kugadziriswa.
Mukupindura mamiriro ezvinhu ari pamusoro apa, nyanzvi dzeindasitiri dzakapa tekinoroji yekubvisa guruva risina kuoma mumakore achangopfuura, iyo yakasimudzirwa muChina. Parizvino, huwandu hwemaovheni anotenderera anoshandisa tekinoroji yekubvisa guruva risina kuoma hunodarika huwandu hwemaovheni anotenderera anoshandisa tekinoroji yekubvisa guruva risina kuoma. Maitiro ekubvisa guruva asina kuoma anoshandisa chinotonhorera chakaoma kuti adzore 20%-25% yemadota akaoma, ayo anoramba aine zvakanakira zvekubvisa guruva rakanyorova uye anokunda zvikanganiso zvematekinoroji ekubvisa guruva akaoma uye akanyorova. Kunyanya, tekinoroji iyi inogona kushandura maitiro ekubvisa guruva rakanyorova pasina kufanira kuibvisa zvachose uye kuigadzirisa semaitiro ekubvisa guruva rakanyorova, kuitira kuti zvivakwa zvepakutanga zvigone kuchengetwa zvakanyanya uye mari yekudyara igone kuchengetwa.
