Sodium Hydrosulfide Method YeKukosha Kwesimbi Kudzoreredza kubva kune Acidic Mvura

kumashure

Mumakumi maviri emakore apfuura, nekukurumidza kusimudzira kwesainzi uye tekinoroji uye kuvaka kwehupfumi, kudiwa kwezvicherwa zviwanikwa kwave kuwedzera zuva nezuva. Kuwanikwa kwezvicherwa zviri nyore uye kusarudzwa imwe chete yakapfuma ores iri kuwedzera kushomeka. Kucherwa kwemaore akaomarara ane akakwenenzverwa akadzamirirwa masikisi uye magiredhi akaderera ari kukwira, uye pane zviri kukura zvinodiwa zvemhando dzakasiyana dzechigadzirwa. Kuzadzisa zvinodikanwa zvezvikamu zvakasiyana-siyana zvehupfumi hwenyika kune zvigadzirwa zvezvicherwa, pane chinodiwa chekukasika kugadzira nzira nyowani dzekugadzirisa zvicherwa dzinoshanda, dzinobatsira mune zvehupfumi, uye dzinobatsira kukutonga kwezvakatipoteredza.

Iyo nzira yekudzoreredza simbi dzakakosha kubva mumvura ine acidic uchishandisa Sodium hydrosulfide ine chiyero chepamusoro chekudzorera uye zvakakosha zvehupfumi. Iyo nzira inosanganisira matanho anotevera:

01.Tangi reKuchengetedza Mvura Yakakwirira

Mvura ine acidic inogadzirwa panguva yekugadzira migodhi inotanga kuyerera ichibva kune yakakwirira-yepamusoro tangi yekuchengetera mvura ichipinda mutangi rekutanga simbi yekubvisa reaction, uko lime inowedzerwa. Iyo trivalent iron ion mumvura ine acidic inonaya pamwe chete necalcium sulfate, uye mazhinji eiyo trivalent iron ayoni anobviswa kubva mumvura ine acid.

02.First Iron Removal Reaction Tank

Iyo reaction liquid inoyerera ichibva kune iron yekubvisa reaction tank ichipinda mutangi rekutanga degassing, uko flocculant inowedzerwa.

03.Second Iron Removal Reaction Tank

Mvura yakasvibirira, iyo yakanyatso kusanganiswa ne lime slurry uye flocculant, inoyerera ichipinda musimbi yekubvisa thickening tank, uko iron hydroxide uye calcium sulfate precipitate inogara kuzasi kwetangi rinowedzera.

04.First Degassing Tank

Mvura ine acidic ine maion anokosha esimbi, kubva mairi iyo yakawanda yeayoni yesimbi yakabviswa, inoyerera negiravhiti ichipinda musimbi sulfide reactor.

05.Metal sulfide Reactor

Musimbi sulfide reactor, mvura ine acidic yakanyatsosanganiswa nesimbi sulfide precipitate uye sodium hydrosulfide, ichigadzira metal sulfide particles.

06.Yechipiri Degassing Tangi

Mvura yakasanganiswa ine metal sulfide concentrate inoyerera negiravhiti ichipinda mutangi rechipiri rekubvisa gassing rakanamirwa kune metal sulfide reactor, uko kunowedzerwa flocculant kukurudzira kuungana kwesimbi sulfide particles kuita zvidimbu zvihombe.

07.Metal sulfide Thickening Tank

Iyo concentrated metal sulfide precipitate inogara pasi pesimbi sulfide thickening tank. A scraper inobvisa iyo yakagadzika precipitate kusvika pakati pepasi pe tanking thickening. Pombi ye reflux inoramba ichidzokorodza chikamu chemvura kubva pasi petangi yakakora ichidzokera kune simbi yekubvisa reaction tank, nepo mvura yasara ichitumirwa kumurwi wedombo nepombi inotakura.

08.Metal sulfide Thickening Tank

Iyo pombi inotenderera inoramba ichidzokorora chikamu chemvura kubva pasi pesimbi sulfide thickening tank kudzokera kusimbi sulfide reactor. Chimwe chikamu chepasi pemvura inotumirwa kune plate-and-frame filter press kuti inaswe mumetal sulfide concentrate.

Zvakanakira nzira yekudzoreredza simbi dzakakosha kubva mumvura ine acidic uchishandisa sodium hydrosulfide ndeaya anotevera:

Kutora simbi dzakakosha kubva mumvura ine acid ine tsvina inogadzirwa nemigodhi kunoda hafu yenzira dzechinyakare dzekugadzira zvicherwa. Iyo giredhi yeakadzoserwa simbi sulfides anosvika zvakapetwa kaviri iyo yechinyakare mamineral process nzira, ine yakanyanya kudzoreredza mwero uye yakakosha mabhenefiti ehupfumi. Mvura yetsvina mushure mekupora ine mashoma eheavy metal ions, zvichikonzera kuderera kwemitengo yekuchenesa mvura yetsvina uye yakanaka mabhenefiti ezvakatipoteredza
