I-Sodium Metabisulphite yinto eqinileyo emhlophe okanye etyheli enevumba elinamandla le-sulphur dioxide ethi ngokuthe ngcembe i-oxidize kwiSodium Sulfate emoyeni.Isetyenziswa ikakhulu ekudayeni, ukuprinta kunye nokudaya, ukusetyenzwa kweeminerali, amayeza, ukutya kunye namanye amashishini.Ukuveliswa kweSodium Metabisulfite ngokuqhelekileyo kuneendlela ezimbini: ezimanzi kunye nezomileyo.Uhlalutyo lovavanyo lufumanise ukuba izalathisi ezininzi zomgangatho weSodium Metabisulfite, eneSodium Carbonate/Soda Ash njengesixhobo sokwenza i-SMBS, phantse yonke intsimbi, iintsimbi ezinzima kwimathiriyeli ekrwada eneSodium Metabisulphite precipitation, kunye nemvula encinci ye-chlorinated substance. .
Kukho izalathisi ezisemgangathweni ezahlukeneyo zeSodium Metabisulphite ngeenjongo ezahlukeneyo.Izalathisi zomgangatho weemveliso ikakhulu zibandakanya umxholo ophambili (% Na2S2O5) kunye nokungcola.Imithombo ephambili yokungcola kwi-Sodium Metabisulphite eyenziwe kwi-Sodium Carbonate yile ilandelayo: i-chloride, isinyithi kunye nentsimbi enzima kakhulu ivela kwi-Soda Ash;I-Sulfate ivela kuphela kwi-oxidation ye-S kwinkqubo yokuvelisa;I-Thiosulfate iveliswa ikakhulu kukusabela kweSulfur kunye neSodium Sulfite ekuhambeni kwesulfure dioxide.Umxholo we-Sodium Sulfite uhambelana nexabiso le-PH yesisombululo xa i-Sodium Metabisulphite ichithwa.
Ngokusebenzisa iimvavanyo eziphindaphindiweyo, sifikelela kwisigqibo sokuba ukucoceka kwezinto eziluhlaza kunye ne-oxidation zizinto ezimbini eziphambili ezichaphazela umgangatho we-Na2S2O5.Umxholo we-Fe yinto ebaluleke kakhulu echaphazela umgangatho we-Sodium Metabisulfite.Umxholo we-iron awuqinile uchaphazela umgangatho we-Na2S2O5, kodwa uphinde uchaphazele ubumhlophe bemveliso yesona sizathu.Intsimbi kwi-SMBS ikakhulu ivela kwi-SO2 yerhasi ekrwada, i-Corrosion yezixhobo zentsimbi kunye nemibhobho yentsimbi inempembelelo enkulu kwinkqubo.Ukulawula umxholo wentsimbi kwi-SO2 igesi eluhlaza kunokuphucula ngokufanelekileyo ubumhlophe bemveliso.
1. Zisa igesi ye-SO2 ekrwada
Ishishini le-SMBS lisebenzisa i-sulfur-rich mineral powder ukulungiselela i-SO2 igesi eluhlaza, equkethe isulfure, isinyithi, i-arsenic, i-zinc, i-lead, i-organic matter kunye nokunye.I-ore powder iyatshiswa ukuvelisa igesi eluhlaza nge-SO2 = 10% -16%.Irhasi ekrwada ihlanjululwa yinkqubo yokucoca kunye negesi ekrwada ye-SO2, emva koko i-synthesis yeSodium Metabisulfite.Ngoko ke, umsebenzi wenkqubo yokucoca ukususwa kwentsimbi kubaluleke kakhulu.
Kwinkqubo ye-toptionchem.com yokuveliswa kwe-SMBS, ukuhlanjululwa okuninzi kwe-SO2 yegesi eluhlaza kwenziwa ukuze kuncitshiswe ngokufanelekileyo umxholo wesinyithi.
Inkqubo imi ngolu hlobo lulandelayo:
I-SO2 yerhasi ekrwada yokususwa kothuli lweNkanyamba Ukususwa kothuli lwe-Electrostatic Ukususwa kothuli oluDynamic Ukususwa kothuli oluMaza oluFakishayo iNqaba yokuhlambela Ukuhlamba Inqaba yamanzi abandayo Ukuhlamba uMbane Ukususwa kwenkungu i-SO2 Fan Pressurized Purified SO2 Gas
2. Zisa ekrwadaSodaAsh
Kwithiyori, ukuveliswa kwe-1MT ye-sodium metabisulfite kufuneka idle malunga ne-600KG yesoda ash.I-Fe kwi-Soda Ash ekrwada yi-27-32mg/kg, kwaye elona xabiso lentsimbi eliziswe kwisoda ash ekrwada yi-18.29mg/kg ngokuthatha umyinge wokubala ixabiso.
3. Yiza namanzi okubonelela
Kukho iintlobo ezine zenkqubo yokubonelela ngamanzi, kubandakanywa amanzi kwisoda ekrwada ash, umphunga, amanzi okuhlamba izixhobo kunye nokususwa kwe-brine entsha.Kwalinganiswa ukuba umxholo wesinyithi owenziwe ngamanzi ahlaziyiweyo wawumalunga ne-0.44mg / kg.
4. Izixhobo zetsimbi kunye nemibhobho yentsimbi idliwe.
Umbhali u tyelele abavelisi abangaphezu kweshumi elinesibini be-Sodium Metabisulphite e-China, kwaye kubalwa ukuba umxholo wesinyithi ongeniswe ngokubola kwezixhobo kunye nemibhobho malunga ne-44mg / kg, echaphazela ubumhlophe beemveliso.
Isishwankathelo, umbhali ukholelwa ukuba umxholo wesinyithi unempembelelo evelele ngakumbi kumgangatho weemveliso ze-Sodium Metabisulfite, ngakumbi ubumhlophe.Imithombo yentsimbi kwi-SMBS ikakhulu ivela kwi-SO2 igesi ekrwada, ukubola kwezixhobo zentsimbi kunye nemibhobho yentsimbi, uthuthu lwesoda ekrwada kunye nonikezelo lwamanzi, phakathi apho isixa sentsimbi esiziswa kukugqwala kwegesi ekrwada ye-SO2, izixhobo zentsimbi kunye nemibhobho yentsimbi kubalwa umlinganiselo omkhulu.Ngaphantsi kwemeko yokuba izixhobo eziphambili azikwazi ukutshintshwa ngokupheleleyo, ukulawula umxholo wentsimbi kwigesi eluhlaza ngumlinganiselo ophambili wokuphucula ubumhlophe bemveliso.Kwimveliso yangempela, amanye amashishini, afana ne-TOPTIONHEM(toptionchem.com), asebenze ngokucokisekileyo kwindlela ephambili yenkqubo, izixhobo zezixhobo kunye nenkqubo yokulungiswa kwegesi ekrwada.Bangakwazi ukuphepha okanye ukunciphisa ukuthatha inxaxheba kwentsimbi ukusuka kumthombo, okanye ukunqanda intsimbi kwikhonkco eliphakathi, ukuze bafezekise injongo yokuphucula umgangatho wemveliso.
