Huremu hweNet: 25, 50, 1000 makirogiramu pabhegi kana zvinoenderana nezvinodiwa nevatengi
Used in the treatment of wastewater .Bvisa oxygen yakawandisa mumvura yetsvina nemapaipi;Mapombi emvura akachena indesalination zvidyarwa nekuti ane antimicrobial agent.
Inoshandiswa muindasitiri yekudhinda nekudhaya bleaching agent mukugadzira pulp, donje nemvere, nezvimwe.
Inoshandiswa muindasitiri yemishonga asan antioxidant additive mune injectableagent zvinodhaka uye semushonga wokuderedza.
Indasitiri yematehwe: Inogona kuita kuti dehwe ripfave, rakagadzirwa zvakanaka, rakaomarara chiratidzo chemvura, kupfeka-kugona Chemical.
Inoshandiswa seore-dressing agent yemumigodhi.Industry Inoshandiswa kugadzira hydrochloride hydroxylamine nezvimwe.
Indasitiri yechikafu: inoshandiswa sekuchengetedza, antioxidant, hupfu hunovandudza
1.Two maitiro ekugadzira sodium pyrosulfite: yakaoma nzira uye nzira yemvura:
1. Dry process : simbisai soda ash nemvura zvakaenzana maererano neimwe molar ratio, uye uzviise mu reactor apo Na2CO3.nH2O inogadzirwa iri muchimiro chezvivharo, chengeta imwe gap pakati pezvivharo, uye wobva wawedzera SO2 kusvikira mhinduro yapera, bvisa zvidhinha, uye zvipwanye kuti uwane chigadzirwa chapera.
2. Wet process : wedzera imwe chiyero chesoda ash mumushonga we sodium bisulfite kuti uite kumira kwe sodium bisulfite, uye wobva wawedzera SO2 kuti uite sodium pyrosulfite makristasi, ayo ari centrifuged uye akaomeswa kuti awane chigadzirwa chakapedzwa.
2.Traditional wet process ye sodium pyrosulfite ine sulfur seyakasvibirira
Chekutanga, pwanya sarufa kuita upfu, uye tumira mweya wakamanikidzwa muchoto chinopfuta pa600 ~ 800 ℃ yekupisa.Huwandu hwemweya hwakawedzerwa hunenge kaviri huwandu hwedzidziso, uye kusungirirwa kweSO2 mugasi ndeye 10 ~ 13.Mushure mekutonhora, kubviswa kweguruva uye kusefa, sublimated sulfur uye kumwe kusvibiswa kunobviswa, uye tembiricha yegesi inoderedzwa kusvika 0 ℃, kuruboshwe kuenda kurudyi, yozotumirwa kune yakatevedzana reactor.
Zvishoma nezvishoma wedzera mai doro uye soda ash mhinduro kune yechitatu reactor ye neutralization reaction.Iyo reaction formula ndeyotevera:
2NaHSO4+ Na2CO3→ 2 Na2SO4+ CO2+ H2O
Iyo inogadzirwa sodium sulfite suspension inopfuudzwa nepakati yechipiri uye yekutanga nhanho reactor, uye yobva yatorwa uye kuita neSO2 kugadzira sodium pyrosulfite crystal.
3.Introduction kuSodium Metabisulfite mukushandiswa kwesimbi mineral processing
Sodium Metabisulfite inoshandiswa zvakanyanya kuindasitiri yemigodhi.Nzira dzekuita mineral processing dzinotevera:
Gravity |Magnetic separation |Kusarudzwa kwemagetsi |Flotation |kemikari chikamu |Photoelectric election |Friction selection |Kunhonga maoko
Flotation: Flotation ndiyo nzira yekuparadzanisa zvicherwa zvinobatsira kubva kune ore, zvichibva pane zvemuviri uye zvemakemikari zvimiro zvemamineral particles.Anenge ese ore anogona kushandiswa mukupatsanura flotation.
Flotation reagents anowanzo shandiswa mukuyangarara: muunganidzi, anopupa mumiririri, anogadzirisa.Pakati pavo, iyo modifier inosanganisirawo inhibitor, activator, pH inogadzirisa mumiriri, inoparadzira mumiriri, flocculant, nezvimwe.
Kubata mumiriri: Mumiriri wekubata ndiwo flotation reagents inoshandura hydrophobicity yemamineral surface, inoita kuti planktonic mineral particle inamate kune bubble.Xanthate, poda yakasviba ndeye anionic muunganidzi.
Kuyerera kwe lead uye zinc ores
Galena (kureva PBS) iminerari yakajairika, imhando ye sulfide.Xanthate nehupfu yakasviba inowanzoshandiswa semubati wekubata (potassium dichromate inhibitor inoshanda).
Sphalerite (ZnS) kemikari yakagadzirwa ndeye sulfide zvicherwa zvakaita seZnS, Makristasi.
Iyo yekubata simba yepfupi ketani alkyl xanthate pane sphalerite haina kusimba kana isingawanikwe.ZnS kana Marmatite isina activation inogona kusarudzwa chete neketani refu mhando xanthate.
Muchikamu chinotevera chenguva, mashandisirwo e xanthate catching agents acharamba achitora chinzvimbo chikuru.Kuti uenderane nezvinodiwa zvekuwedzera kuoma kweSphalerite flotation, kusanganiswa kwemishonga kwakakosha, zvakare inzira inoshanda yekunyatso tora mukana wemishonga yechivanhu.
Iyo huru flotation inhibitor ndeiyi inotevera:
1. Lime (CaO) ine mvura yakasimba, inobata nemvura kuti ibudise hydrated lime Ca (OH) 2.Lime inoshandiswa kunatsiridza pH yepulp, inhibit ye iron sulfide minerals.Mune sulfide mhangura, mutungamiri, zinc ore, inowanzobatanidzwa ne sulfided iron ore.
2. Cyanide (KCN, NaCN) inhibitor inobudirira yekuparadzanisa mutungamiri uye zinc.Mune alkaline pulp, CN concentration inowedzera, iri kutsigira inhibition.
3. Iyo sterling yeZinc Sulfate ikristaro chena, inonyungudika mumvura, ndiyo inhibitor ye sphalerite, kazhinji mu alkaline pulp ine simba rekudzivisa.
4. Kiyi inotamba mabasa ekudzivirira mu sulfite, sulfite, SO2 inonyanya kuve HSO3－.Sulfur dioxide uye sub sulfuric acid (munyu) inonyanya kushandiswa mukudzivisa Pyrite uye sphalerite.Asidhi isina simba yemugodhi pulp yakagadzirwa neraimu kubva kuSulfur dioxide (pH=5～7), kana kushandisa Sulfur dioxide, zinc sulfate, ferrous sulfate uye ferric sulfate pamwe chete se inhibitor.Nokudaro galena, pyrite, sphalerite inodziviswa.Iyo inhibited sphalerite inogona kushandiswa nehuwandu hwemhangura sulfate.Uyewo inogona kushandisa Sodium thiosulfate, sodium metabisulfite kutsiva sulfite, inhibit sphalerite uye iron pyrites (inowanzozivikanwa seFeS2).
Kuchengeta:
Inofanira kuchengetwa munzvimbo inotonhorera uye yakaoma.Iyo package ichavharwa kudzivirira mweya oxidation.Teerera kune unyoro.Ichadzivirirwa kubva kumvura uye kuchiedza chezuva panguva yekufambisa.Izvo zvinorambidzwa zvachose kuchengeta uye kutakura pamwe chete nemaasidhi, oxidants uye zvinokuvadza uye zvine chepfu zvinhu.Ichi chigadzirwa hachifanirwe kuchengetwa kwenguva yakareba.Bata nehanya panguva yekurodha uye kuburitsa kudzivirira kupaza kwepakeji.Kana pane moto, mvura uye zvakasiyana-siyana zvekudzimisa moto zvinogona kushandiswa kudzima moto.
Packing:
Yakaiswa mumabhegi epurasitiki akarukwa akaiswa mapurasitiki epolyethylene, bhegi rega rega rine huremu hwe25kg kana 50kg.1. Sodium metabisulfite yakarongedzerwa mumabhegi epurasitiki akarukwa kana madhiramu, akaiswa masaga epurasitiki, ane huremu hwemambure e25 kana 50kg;1100 kg net heavy packing bag.
2. Chigadzirwa chacho chichadzivirirwa kubva pakukuvadza, unyoro uye kupisa kwekushisa panguva yekufambisa uye kuchengetedza.Inorambidzwa kugarisana ne oxidant uye acid;
3. Nguva yekuchengetedza yechigadzirwa ichi ( Sodium metabisulfite ) mwedzi mitanhatu kubva pazuva rekugadzirwa.
