1.Ob txheej txheem ntawm sodium pyrosulfite: txheej txheem qhuav thiab ntub txheej txheem:
1. Cov txheej txheem qhuav : do cov dej qab zib tshauv thiab dej sib npaug raws li cov molar piv, thiab muab tso rau hauv lub reactor thaum Na2CO3.nH2O generated yog nyob rau hauv daim ntawv ntawm blocks, khaws ib tug tej qhov sib txawv ntawm cov blocks, thiab ces ntxiv SO2 kom txog rau thaum cov tshuaj tiv thaiv tiav, tshem tawm cov blocks, thiab zuaj lawv kom tau cov khoom tiav.
2. Cov txheej txheem ntub dej: ntxiv ib qho nyiaj soda tshauv rau hauv cov tshuaj sodium bisulfite ua rau nws tsim kev ncua ntawm sodium bisulfite, thiab tom qab ntawd ntxiv SO2 los ua sodium pyrosulfite crystals, uas yog centrifuged thiab qhuav kom tau cov khoom tiav.
2.Traditional ntub txheej txheem ntawm sodium pyrosulfite nrog sulfur li raw khoom
Ua ntej, zuaj cov sulfur rau hauv cov hmoov, thiab xa cov cua compressed rau hauv lub qhov cub combustion ntawm 600 ~ 800 ℃ rau combustion.Cov huab cua ntxiv yog kwv yees li ob zaug ntawm qhov theoretical, thiab qhov concentration ntawm SO2 hauv cov pa roj yog 10 ~ 13.Tom qab txias, tshem tawm plua plav thiab pom, sublimated sulfur thiab lwm yam impurities raug tshem tawm, thiab cov roj kub yog txo mus rau 0 ℃, sab laug mus rau sab xis, thiab ces xa mus rau series reactor.
Maj mam ntxiv niam cawv thiab dej qab zib tshauv tov rau lub reactor thib peb rau neutralization cov tshuaj tiv thaiv.Cov tshuaj tiv thaiv mis yog raws li nram no:
2 NaHSO4+ Na2CO3→ 2 Na2SO4+ CO2+ H2O
Cov tshuaj sodium sulfite raug tshem tawm yog dhau los ntawm qhov thib ob thiab thawj theem reactors nyob rau hauv lem, thiab ces absorbed thiab reacted nrog SO2 los tsim sodium pyrosulfite crystal.
3.Introduction to Sodium Metabisulfite nyob rau hauv daim ntawv thov ntawm hlau ntxhia ua
Sodium Metabisulfite yog dav siv rau kev lag luam mining.Cov txheej txheem ntawm kev ua ntxhia yog raws li hauv qab no:
Lub ntiajteb txawj nqus |Sib nqus sib cais |Kev xaiv hluav taws xob |Flotation |tshuaj xaiv |Photoelectric kev xaiv tsa |Kev sib txhuam xaiv |Kev xaiv tes
Flotation: Flotation yog cov txheej txheem ntawm kev sib cais cov khoom muaj txiaj ntsig ntawm cov ore, raws li lub cev thiab tshuaj lom neeg ntawm cov ntxhia hauv cov khoom.Yuav luag tag nrho cov ore tuaj yeem siv rau hauv kev sib cais flotation.
Flotation reagents feem ntau siv hauv flotation: collector, foaming agent, modifier.Ntawm lawv, tus hloov kho kuj muaj xws li inhibitor, activator, pH kho tus neeg sawv cev, dispersing tus neeg sawv cev, flocculant, thiab lwm yam.
Catching agent: Catching agent yog flotation reagents uas hloov hydrophobicity ntawm pob zeb hauv av, ua rau planktonic ntxhia particle adhere rau npuas.Xanthate, dub hmoov yog anionic collector.
Flotation ntawm txhuas thiab zinc ores
Galena (piv txwv li PBS) yog ib qho ntxhia uas feem ntau, nws yog ib hom sulfide.Xanthate thiab dub hmoov feem ntau yog siv los ua tus neeg saib xyuas (potassium dichromate yog ib qho zoo inhibitor).
Sphalerite (ZnS) tshuaj muaj pes tsawg leeg yog sulfide minerals xws li ZnS, Crystals.
Lub peev xwm ntes ntawm luv saw alkyl xanthate ntawm sphalerite tsis muaj zog lossis tsis muaj.ZnS lossis Marmatite yam tsis muaj kev ua haujlwm tuaj yeem xaiv tau los ntawm cov saw ntev ntev hom xanthate.
Nyob rau lub sijhawm tom ntej, cov ntawv thov ntawm xanthate ntes cov neeg ua haujlwm yuav txuas ntxiv mus tuav txoj haujlwm tseem ceeb.Txhawm rau hloov kho kom haum rau qhov kev thov ntawm kev ua kom yooj yim Sphalerite flotation, kev sib xyaw ntawm lub tsev muag tshuaj yog qhov tseem ceeb, nws kuj yog ib txoj hauv kev zoo los ua kom muaj peev xwm ntawm cov tshuaj ib txwm siv.
Lub ntsiab flotation inhibitor yog raws li nram no:
1. Txiv qaub (CaO) muaj zog nqus dej, ua nrog dej los tsim hydrated txiv qaub Ca(OH)2.Txiv qaub yog siv los txhim kho pH ntawm cov tawv nqaij, inhibition ntawm hlau sulfide minerals.Nyob rau hauv sulfide tooj liab, txhuas, zinc ore, feem ntau txuam nrog sulfide hlau ore.
2. Cyanide (KCN, NaCN) yog ib qho zoo inhibitor rau kev sib cais ntawm cov hlau lead thiab zinc.Hauv alkaline pulp, CN concentration nce, uas yog nyob rau hauv kev pom zoo ntawm inhibition.
3. Lub sterling ntawm Zinc Sulfate yog dawb siv lead ua, soluble nyob rau hauv dej, yog tus inhibitor ntawm sphalerite, feem ntau nyob rau hauv lub alkaline pulp nws muaj cov nyhuv inhibition.
4. Tus yuam sij uas ua lub luag haujlwm inhibition hauv sulfite, sulfite, SO2 yog HSO3-.Sulfur dioxide thiab sub sulfuric acid (ntsev) yog siv rau hauv inhibition ntawm Pyrite thiab sphalerite.Tsis muaj zog acid mine pulp ua los ntawm txiv qaub los ntawm Sulfur dioxide (pH = 5 ~ 7), los yog siv sulfur dioxide, zinc sulfate, ferrous sulfate thiab ferric sulfate ua ke ua inhibitor.Yog li galena, pyrite, sphalerite yog inhibited.Lub inhibited sphalerite tuaj yeem qhib tau los ntawm me me ntawm tooj liab sulfate.Kuj tseem tuaj yeem siv Sodium thiosulfate, sodium metabisulfite los hloov sulfite, los tiv thaiv sphalerite thiab hlau pyrites (feem ntau hu ua FeS2).
