Caustic Calcined Magnesite Powder rau Flue Gas Treatment

Caustic calcined magnesite hmoov rau flue gas kho; spaying ntawm nplua thiab reactive magnesia hmoov ntawm lub preheaters (LUVO) Nyob rau hauv lub zog nroj tsuag los yog loj chav tsev ntau lawm, MgO tuaj yeem hnov ​​​​mob nrog sulfur trioxide (SO3). SO3 yog cov oxide ntawm SO2, uas yog cov pa khib nyiab los ntawm kev hlawv roj los yog thee. Muab piv nrog calcium oxide, qhov zoo ntawm magnesium yog tias cov tshuaj tiv thaiv ntawm magnesium sulfate yog soluble. Qhov ntawd yuav tsis tso nyiaj lossis thaiv lub tsev.

Caustic calcined magnesite hmoov rau flue gas kho kuj siv, raws li hauv qab no:
1. Rau ammonium nitrate prills, MgO yog siv los tiv thaiv lawv cov qauv kev ncaj ncees.
2. Rau refractory, MgO yog siv los ua tus neeg sawv cev refractory hauv kev tsim cov crucibles.
3. Rau cov av decontamination, MgO yog siv los precipitate hnyav hlau hauv av.
4. Hauv kev kho dej, Caustic Calcined Magnesia tuaj yeem muab cov kab mob alkaline los tswj cov sulfur acid tiam thiab tom qab ntawd tiv thaiv lub network kom tsis txhob raug corroded.
