Indlela yeSodium Hydrosulfide yokuBuyiselwa kweNtsimbi eneXabiso kuManzi ane-Acidic

imvelaphi

Kwiminyaka engamashumi amabini edlulileyo, kunye nophuhliso olukhawulezayo lwesayensi kunye nobuchwepheshe kunye nokwakhiwa kwezoqoqosho, imfuno yemithombo yezimbiwa iye yanda imihla ngemihla. Ubukho bokumbiwa lula kunye nezikhethiweyo ezityebileyo ezikwi-single enye buya buqatsela. Ukwembiwa kwentsimbi ekrwada entsonkothileyo enobungakanani bamasuntswana amahle kunye namabanga aphantsi kuyakhula, kwaye kukho iimfuno ezikhulayo zokwahluka kwemveliso kunye nomgangatho. Ukuhlangabezana neemfuno zamacandelo ngamacandelo oqoqosho lwesizwe kwiimveliso zezimbiwa, kukho imfuneko engxamisekileyo yokuphuhlisa iindlela ezintsha zokulungiswa kwezimbiwa ezisebenzayo, eziluncedo kwezoqoqosho, nezilungele ulawulo lokusingqongileyo.

Indlela yokubuyisela isinyithi esixabisekileyo kumanzi aneasidi kusetyenziswa Isodiyam hydrosulfide inezinga eliphezulu lokubuyisela kunye neenzuzo ezibalulekileyo zoqoqosho. Inkqubo ibandakanya la manyathelo alandelayo:

01.ITanki yokuGcina amanzi ekwinqanaba eliphezulu

Amanzi aneasidi aveliswa ngexesha lenkqubo yokwemba aqala aqukuqele ukusuka kwitanki yokugcina amanzi ekwinqanaba eliphezulu ukuya kwitanki yokuqala yokususa intsimbi, apho i-lime yongezwa khona. I-ioni ye-iron e-trivalent emanzini ane-acidic precipitate kunye ne-calcium sulfate, kwaye ininzi ye-iron ion ye-trivalent iyasuswa emanzini ane-acidic.

02.Itanki yokuQala yokuSuswa kwentsimbi yokuQala

Ulwelo olusabelayo luqukuqela ukusuka kwitanki yokususa intsimbi ukuya kwitanki yokuqala yokukhupha amanzi, apho i-flocculant yongezwa khona.

03.Itanki yeSibini yokuSuswa kwentsimbi

Amanzi akrwada, axutywe kakuhle nodaka lwekalika kunye neflocculant, aqukuqela ukuya kwitanki yokujiya yokususa intsimbi, apho i-iron hydroxide kunye ne-calcium sulfate precipitate zihlala emazantsi etanki yokujiya.

04.Itanki yokuQala yokuHlangula

Amanzi ane-acidic aqukethe i-ion zentsimbi ezixabisekileyo, apho kususwe inani elikhulu lee-ion ze-iron trivalent, lihamba ngokuxhuzula kwi-metal sulfide reactor.

05.Metal Sulfidi Reactor

Kwi-metal sulfide reactor, amanzi ane-acidic axutywe ngokucokisekileyo kunye ne-metal sulfide precipitate kunye ne-sodium hydrosulfide, evelisa i-metal sulfide particles.

06.Itanki yokukhupha iGassing yesibini

Ulwelo oluxubeneyo oluqulethe i-metal sulfide concentrate luqukuqela ngokuxhuzula kwitanki yesibini ye-degassing encanyathiselwe kwi-metal sulfide reactor, apho i-flocculant yongezwa ukukhuthaza ukudityaniswa kwamasuntswana e-metal sulfide kumasuntswana amakhulu.

07.Metal sulfide Thickening Tank

I-metal sulfide precipitate egxininisiweyo ihlala ezantsi kwetanki yokujiya ye-metal sulfide. I-scraper isusa i-precipitate ehleliweyo ukuya embindini wezantsi kwetanki yokujiya. Impompo ye-reflux iqhubeka nokurisayikilisha inxenye yemvula ukusuka ezantsi kwetanki yokujiya ibuyele kwitanki yokususa intsimbi, ngelixa i-precipitate eseleyo ithunyelwa kwimfumba yamatye ngempompo yokuhambisa.

08.Metal sulfide Thickening Tank

Ipompo yokujikeleza iphinda isebenzise kwakhona inxalenye yemvula ukusuka ezantsi kwetanki yokujiya ye-metal sulfide ibuyele kwi-metal sulfide reactor. Esinye isahlulo somzantsi we-precipitate sithunyelwa kwi-plate-and-frame filter press ukuze igxininiswe kwi-metal sulfide concentrate.

Iingenelo zendlela yokubuyisela isinyithi esixabisekileyo kumanzi aneasidi usebenzisa i-sodium hydrosulfide zezi zilandelayo:

Ukufumana ngokuthe ngqo isinyithi esixabisekileyo kumanzi amdaka aneasidi aveliswa yimigodi kubiza malunga nesiqingatha seendlela zokusetyenzwa kwezimbiwa. Ibakala leesulfide zesinyithi ezixabisekileyo ezifunyenweyo liphantse liphindeke kabini elo leendlela zokusetyenzwa kwezimbiwa eziqhelekileyo, ezinezinga eliphezulu lokubuyisela kunye neenzuzo ezibalulekileyo zoqoqosho. Amanzi amdaka emva kokubuyisela aqulethe i-ion zetsimbi enzima, ezibangela iindleko eziphantsi zokucocwa kwamanzi amdaka kunye neenzuzo ezilungileyo zokusingqongileyo
