Parizvino, kudzvanywa kwekuchengetedzwa kwezvakatipoteredza kwechoto chinotenderera chekugadzira simbi yakakura. Pakati pavo, iyo guruva yekubvisa sisitimu yeinotenderera choto flue gasi ndiyo inonyanya kukosha, uye zvinodikanwa kuita shanduko yakachena kuti uwane ultra-low emissions. Naizvozvo, kusarudzwa uye kushandiswa kweiyo inoshanda, yakachengeteka uye yakaderera-inoshandiswa inotenderera choto dedusting tekinoroji yave nyaya yekukurumidzira yemabhizinesi esimbi nesimbi.
Iyo yakanyorova nzira uye yakaoma nzira yekutenderera choto flue gasi dedusting vane zvakanakira zvavo
Kutenderedza choto chekunyorova dedusting tekinoroji inopfupikiswa seOG. OG ndiko kupfupikiswa kweOxygen rotating furnace Gas Recovery muChirungu, zvinoreva okisijeni inotenderera choto kudzoreredza gasi. Icho choto chinotenderera uchishandisa OG tekinoroji inoburitsa yakakura-yepamusoro-tembiricha uye yakakwirira-yakadzika CO flue gasi muchoto nekuda kwechisimba oxidation reaction panguva yekuridza. Iyo flue gasi inodzvinyirira kupindira kwemhepo yakatenderedza kuburikidza nekusimudza siketi uye kutonga kweiyo flue gasi kumanikidza mukati mehood. Panyaya yekusapiswa, tekinoroji inotora iyo vaporization inotonhorera flue kutonhorera iyo flue gasi, uye mushure mekucheneswa neaviri-nhanho Venturi chubhu muunganidzi weguruva, inopinda mugasi kudzoreredza uye kuburitsa system.
Kutenderera choto chakaoma guruva kubvisa tekinoroji inopfupikiswa seLT. TheLTnzira yakagadzirwa pamwe chete naLurgi naThyssen muGermany.LTndiko kudimburirwa kwemazita emakambani maviri aya. Iyi tekinoroji inoshandisa vaporization inotonhorera kutonhorera flue gasi, uye mushure mekucheneswa necylindrical yakaoma electrostatic precipitator, inopinda mugasi kudzoreredza uye kuburitsa system. Mutemo uyu wakatanga kushandiswa muzvirongwa zvekudzoreredza gasi muna 1981.
Kutenderera choto chakaoma dedusting tekinoroji ine hombe yenguva imwe chete yekudyara, yakaoma chimiro, zvakawanda zvinodyiwa, uye yakanyanya kuoma kwehunyanzvi. Mwero wekusimudzira musika munyika yangu uri pasi pe20%. Zvakare, tekinoroji yekubvisa huruva yakaoma inoshandisa hombe yakaoma yemagetsi precipitator kubvisa viscous yekutanga inotenderera guruva rechoto. Muunganidzi weguruva ari nyore kuunganidza guruva uye guruva rinobuda harina kugadzikana.
Kana ichienzaniswa neyakaoma yekubvisa guruva, iyo OG yakanyorova yekubvisa guruva ine chimiro chakareruka, yakaderera mutengo, uye yakanyanya kucheneswa kushanda zvakanaka, asi ine zvipingamupinyi zvakadai sekunyanya kushandiswa kwesimba, kushandiswa kwemvura kukuru, kuomarara kwetsvina, uye kudhura kwekushandisa. Uyezve, tekinoroji yekubvisa guruva inosuka inosuka guruva rose mumvura zvisinei nekukura kwechikamu, zvichikonzera kuwanda kweguruva rekubvisa tsvina. Kunyangwe iyo tekinoroji nhanho yeyakaoma uye yakanyorova dedusting maitiro yakaramba ichivandudzwa mukuita kwenzvimbo, hurema hwavo hwakasiyana hwave husati hwagadziriswa.
Mukupindura mamiriro ari pamusoro, nyanzvi dzeindasitiri dzakakurudzira tekinoroji yekubvisa guruva mumakore achangopfuura, iyo yakasimudzirwa kuChina. Parizvino, nhamba inotenderera yevira uchishandisa semi-yakaoma dedusting tekinoroji inodarika nhamba yemoto unotenderera uchishandisa yakaoma dedusting tekinoroji. Iyo semi-dry dedusting process inoshandisa yakaoma evaporative inotonhorera kudzoreredza 20% -25% yemadota akaoma, ayo anochengeta zvakanakira nekunyorovesa dedusting uye kukunda hurema hweakaoma uye akanyorova ekubvisa tekinoroji. Kunyanya, tekinoroji iyi inogona kushandura iyo yakanyorova dedusting maitiro pasina kuita dismantle zvachose uye redo it seyakaoma dedusting maitiro, kuitira kuti yepakutanga zvivakwa zvinogona kuchengetwa kusvika pamwero mukuru uye mari yekudyara inogona kuchengetwa.
