Konutai Metabisulfite Na2S2O5
Ko te Sodium Metabisulfite he ma, he kowhai kowhai ranei te paura tioata, he karaihe iti ranei, me te kakara kaha o te SO2, te taumaha motuhake o te 1.4, te wairewa i roto i te wai, he waikawa te wairewa wai, ko te whakapiri ki te waikawa kaha ka tuku i te SO2 me te whakaputa i nga tai e rite ana, he roa te wa i te rangi. , ka oxidized ki na2s2o6, kia kore e taea e te hua te ora mo te wa roa.Ina teitei ake te mahana i te 150 ℃, ka pirau te SO2. Ka huri te Sodium Metabisulfite hei paura, ka whakamahia ki te maha o nga momo whakamahinga mai i te whakamarumaru ki te maimoatanga wai.Ko te Wit-stone te kawe i nga momo me nga tohu katoa o te Sodium Metabisulfite.

1.Two tukanga production o te konutai pyrosulfite: tukanga maroke me te tukanga mākū:
1. Tukatuka maroke : whakakorikorihia te pungarehu houra me te wai kia rite ki tetahi tauwehenga molar, ka maka ki roto i te reactor ka te Na2CO3.Ko te nH2O i hangaia he poraka, kia mau ki tetahi waahi i waenganui i nga poraka, katahi ka tapiri atu ki te SO2 kia mutu ra ano te tauhohenga, tangohia nga poraka, ka kuru kia whiwhi i te hua kua oti.
2. Te tukanga maku : whakauruhia he pungarehu houra ki roto i te otinga konutai bisulfite hei hanga i te whakatārewatanga o te konutai bisulfite, katahi ka tapiri atu ki te SO2 hei hanga tioata konutai pyrosulfite, ka whakamarokehia, ka whakamaroke kia whiwhi ai i te hua kua oti.
2.Tuhinga maku o te konutai pyrosulfite me te whanariki hei rauemi mata
Tuatahi, kuru i te whanariki ki te paura, ka tuku hau kōpeke ki roto i te oumu ngingiha i te 600~800 ℃ mo te ngingiha.Ko te nui o te hau e tapirihia ana e rua pea te nui o te whakaaro, a ko te kukū o SO2 i roto i te hau ko te 10~13.I muri i te whakamatao, te tango i te puehu me te tātari, ka tangohia te whanariki sublimated me etahi atu poke, ka heke te pāmahana hau ki te 0 ℃, maui ki te taha matau, ka tukuna ki te reactor raupapa.
Āta tāpirihia te waipiro whaea me te wairewa pungarehu houra ki te reactor tuatoru mo te tauhohenga whakaheke.Ko te tauira tauhohenga e whai ake nei:
2NaHSO4+ Na2CO3→ 2 Na2SO4+ CO2+ H2O
Ko te whakatārewatanga konutai sulfite ka tukuna ki roto i nga reactors tuarua me te tuatahi, ka uru, ka tauhohe ki te SO2 hei whakaputa i te konutai pyrosulfite tioata.
3.Introduction ki te Sodium Metabisulfite i roto i te whakamahinga o te tukatuka kohuke whakarewa
Ko te konutai Metabisulfite e whakamahia nuitia ana mo te umanga maina.Ko nga tikanga mo te tukatuka kohuke e whai ake nei:
Gravity |Wehenga aukume |Kōwhiringa hiko |Maranga |kōwhiringa matū |Te pōtitanga whakaahua |Kōwhiringa waku |Te kohi ringa
Te Maranga: Ko te Maranga te tikanga wehe i nga kohuke whaihua mai i te kohuke, i runga i nga ahuatanga o te tinana me te matū o nga matūriki kohuke.Tata ki te katoa o te ore ka taea te whakamahi i te wehenga rererangi.
Ko nga reagents Flotation e whakamahia nuitia ana i roto i te rere: kaikohi, kaihoko pahuka, whakarereke.I roto i a raatau, kei roto ano i te whakarereke te aukati, te kaiwhakaoho, te kaiwhakatikatika pH, te kaihoko whakamarara, te flocculant, etc.
Kaipupuri hopu: Ko te kaihoko hopu he reagents flotation e whakarereke ana i te hauwai o te mata kohuke, ka piri te matūriki kohuke planktonic ki te mirumiru.Ko te Xanthate, te paura pango he kaikohi anionic.
Te rewa o te mata me te konutea ores
Ko Galena (arā, PBS) he kohuke noa, he momo sulfide.Ko te Xanthate me te paura pango ka whakamahia hei kaikawe hopu (ko te konupora dichromate he aukati whai hua).
Sphalerite (ZnS) hanganga matū he kohuke sulfide pērā i ZnS, Tioata.
Ko te kaha hopu o te alkyl xanthate mekameka poto i runga i te sphalerite he ngoikore, kaore ranei i te waatea.Ko te ZnS me te Marmatite me te kore whakahohe ka taea anake te kowhiri ma te momo mekameka roa xanthate.
I te wa e whai ake nei, ka noho tonu nga tono a nga kaihoko hopu xanthate ki te waahi rangatira.Hei urutau ki te hiahia o te piki haere o te rerenga Sphalerite, he mea nui te whakakotahitanga o te rongoa, he huarahi whai hua ano ki te tarai i te kaha o te rongoa tuku iho.
Ko te aukati matua o te pupuhi ko enei e whai ake nei:
1. Ko te kotakota (CaO) he kaha te momi wai, ka mahi ki te wai hei whakaputa i te kotakota Ca(OH)2.Ka whakamahia te kotakota hei whakapai ake i te pH o te penupenu, hei aukati i nga kohuke sulfide rino.I roto i te parahi sulfide, mata, konutea ore, he maha nga wa e hono ana ki te rino rino sulfide.
2. Ko te Cyanide (KCN, NaCN) he aukati whai hua mo te wehenga o te mata me te zinc.I roto i te penupenu kawakore, ka piki te kukū o te CN, he pai ki te aukati.
3. Ko te sterling o Zinc Sulfate he karaihe ma, he wairewa i roto i te wai, ko te aukati o te sphalerite, i te nuinga o te waa i roto i te penupenu kawakore he painga o te aukati.
4. Ko te matua e mahi ana i nga mahi aukati i roto i te sulfite, sulfite, SO2 ko te nuinga HSO3-.Ko te whanariki hauhā me te waikawa pungatara iti (te tote) ka whakamahia hei aukati i te Pyrite me te sphalerite.Ko te penupenu maina waikawa ngoikore i hangaia ki te kotakota mai i te Sulfur dioxide (pH=5~7), ka whakamahi ranei i te Sulfur dioxide, te zinc sulfate, te ferrous sulfate me te ferric sulfate hei aukati.Ko te galena, pyrite, sphalerite ka aukati.Ko te sphalerite kua whakakorehia ka taea te whakahohe ma te iti o te konukura sulfate.Ka taea hoki te whakamahi i te Sodium thiosulfate, te konutai metabisulfite hei whakakapi i te sulfite, hei aukati i te sphalerite me te piriti rino (e mohiotia ana ko FeS2).
Rokiroki:
Me penapena i roto i te whare putunga makariri me te maroke.Me hiri te kete ki te aukati i te hau.Kia tupato ki te makuku.Ka tiakina mai i te ua me te ra i te wa e kawe ana.Ka tino rahuitia te penapena me te kawe tahi me nga waikawa, nga mea hāora me nga matū kino me te paitini.Kaua tenei hua e rongoa mo te wa roa.Kia tupato i te wa e utaina ana me te tango kia kore ai e pakaru te kete.Mena he ahi, ka taea te whakamahi wai me nga momo momo tinei ahi hei tineia te ahi.
Tapeke:
Ka mau ki roto i nga peeke raranga kirihou kua kapihia ki nga peeke polyethylene, he 25kg, 50kg te taumaha o ia peeke.1. Ko te konutai metabisulfite ka whakakiia ki roto i nga peeke raranga kirihou, i nga peeke ranei, kua kapi ki nga peeke kirihou, me te taumaha kupenga o te 25 ki te 50kg ranei;1100 kirokaramu kupenga peeke takai taumaha.
2. Ka tiakina te hua mai i te kino, te makuku me te wera i te wa o te kawe me te rokiroki.Karekau kia noho tahi me te oxidant me te waikawa;
3. Ko te wa rokiroki o tenei hua ( Sodium metabisulfite ) he 6 marama mai i te ra o te whakaputanga.
