Yintoni umsebenzi wokutyebisa?

Inkqubo yokuqina ibandakanya ukuhlukana komxube oqinileyo wolwelo ukuya kwi-dense underflow kunye nokuphuphuma okucacileyo ngokuqhelekileyo. Eyangaphambili iqulethwe ngamasuntswana aqinileyo kwaye okokugqibela akubandakanyi ukungcola kangangoko kunokwenzeka. Inkqubo yokwahlula sisiphumo somxhuzulane. Onke amasuntswana ngokobukhulu obahlukeneyo kunye noxinaniso enza iileya ezahlukeneyo ngetanki.

Iinkqubo zokujiya zenzeka kwitanki yentlenga kulungiso lwezimbiwa zokwahlulwa komxinwa kunye neentsalela zezimbiwa.

Amanqaku omlinganiselo ayimfuneko ekutyebeni

Iimitha zokuxinana kolwelo kwi-Intanethiziyafuneka ukwandisa ukusebenza kwee-thickeners. Umzekelo, iindawo zokufakela ziquka ukutya, ukuphuphuma kwamanzi, ukuphuphuma kunye nokungaphakathi kwetanki ye-thickener. Kwiimeko ezingentla, ezi zoluvo zinokuthathwa njengeimitha yobuninzi bodakaokanyeimitha yobuninzi bodaka. Zikwaluncedo ekuphuculeni ulawulo oluzenzekelayo lokuqhuba, iimpompo kunye nedosing esebenzayo yeeflocculants.

Izizathu zoMlinganiselo woXinano

Izizathu zomlinganiselo woxinaniso zinokwahluka nganye nganye. Le miqathango mihlanu ilandelayo igxininisa ukubaluleka kokujongwa koxinaniso ukulungiselela ukuphuculwa kwemizi-mveliso.

No. 1 Ukubuyiswa kwamanzi

Amanzi athathwa njengeyona nto ibalulekileyo kwishishini lemigodi nezimbiwa. Ke ngoko, ukubuyiswa kwamanzi okanye ukusetyenziswa kwakhona kwamanzi konga iindleko zokujiya kakhulu. Ukukhula okuncinci kwe-1-2% kuxinano lokuhamba ngaphantsi kwamanzi kuthetha isixa esikhulu samanzi afunekayo kufakelo lokusebenza. Ukwanda koxinano kusebenza ngokufanelekileyo ekuqinisekiseni ukuqina kumadama asalayo, anokuthi adilike xa kukho ulwelo oluninzi olumpontshelwe emadamini.

No. 2 Mineral Recovery

Kwii-thickeners ezigxininisiweyo, isondlo ngokuqhelekileyo sisuka kwisekethi ye-flotation. I-Flotation ibandakanya ukwahlula amasuntswana ngomxhuzulane. Ngamanye amazwi, abo banamaqamza omoya ancamatheleyo banyukela phezulu kwaye basuswe, ngelixa abanye bahlala kwinqanaba lolwelo. Xa le nkqubo isenzeka kwi-thickener yemveliso, i-foam inokuthwala izinto eziqinileyo kwi-overflow.

Ezi ziqina zixabisekile kwaye, ukuba aziphindanga kwakhona, zinokunciphisa izinga lokubuyiswa kwentsimbi egxininisiweyo. Ukongezelela, i-solids kwi-overflow ingakhokelela kwiindleko eziphezulu ze-reagent, umonakalo kwiimpompo kunye ne-valve, kunye neendleko ezongeziweyo zokugcinwa, ezifana nokucoca iitanki zamanzi xa i-solids iqokelela apho.

Malunga ne-90% yezinto eziqinileyo ezilahlekileyo ekuphuphumeni kwazo ziye zifumaneke kumanqanaba okugqibela enkqubo (umz., emathangini nasemadamini). Nangona kunjalo, i-10% eseleyo, emele ixabiso elibalulekileyo lezoqoqosho, ilahleka ngokusisigxina. Ukunciphisa ilahleko yezinto eziqinileyo ekuphuphumeni kufuneka ke kube yinto ephambili. Utyalo-mali kubuchwephesha bolawulo lwenkqubo kunokunyusa izinga lokubuyisela kwakhona kwaye kuzise imbuyekezo ekhawulezileyo kutyalo-mali.

Ukusetyenziswa kweLonnmeteriimitha zobuninzikwayeiimitha zokuhambakwi-underflow yenza ukuba iliso elingcono ekusebenzeni kwe-thickener. Ukufunyaniswa kwexesha langempela kwizinto eziqinileyo kwi-overflow kuyenzeka kwakhona kunye noxinzelelo okanye iimitha eziqinileyo. Iimpawu ze-4-20mA zezixhobo zinokudibaniswa kwinkqubo yokulawula ukulungiswa kwenkqubo ngokuthe ngqo.

3 Ukusetyenziswa ngokufanelekileyo kwe-Flocculant

Ii-flocculants zisebenza ekuphuculeni ukusebenza kwentlenga, oko kukuthi, iikhemikhali eziququzelela amasuntswana kulwelo ukuba adibane. Idosi yeeflocculants iqwalasela ulawulo lweendleko kwi-reagent kunye nokusebenza kakuhle. Imitha yoxinaniso ivumela ulawulo loxinaniso oluchanekileyo noluthembekileyo kwisondlo esityebileyo. Injongo kukuphumeza eyona pesenti iphezulu ye-solids ngobunzima kwi-slurry yokutya ngelixa uvumela ukuhlalisa amasuntswana asimahla. Ukuba ingxinano ye-slurry yokutya ingaphezulu kwethagethi, kufuneka kongezwe utywala benkqubo, kwaye kunokufuneka amandla okuxuba ngakumbi ukuqinisekisa ukutya okwaneleyo kuxutywa kakuhle.

Umlinganiselo wexesha lokwenyani loxinaniso lwefidi slurry usebenzisa imitha yoxinano olungaphakathi lubalulekile kulawulo lwenkqubo. Oku kuqinisekisa ukusetyenziswa kakuhle kwe-flocculant kunye nokwandisa inkqubo yokuxuba, ukugcina i-thickener isebenza ngaphakathi koluhlu olujoliswe kuyo.

4 Ukufunyanwa kwangoko kweengxaki ze-Flocculation

AbaSebenzisi bazama ukugcina iimeko ezizinzileyo kwii-thickeners, ukuphumeza ukuphuphuma okucacileyo kunye nokuqiniswa okuncinci kunye nokuhamba ngaphantsi kwe-dense kunye nolwelo oluncinci. Nangona kunjalo, iimeko zenkqubo zinokutshintsha ngokuhamba kwexesha, ezinokukhokelela ekuzinziseni kakubi, ukunciphisa ukuxinana kokuhamba ngaphantsi, kunye nezinto eziqinileyo eziphezulu ekuphuphumeni. Le miba inokuvela kwiingxaki ze-flocculation, umoya okanye ugwebu etankini, okanye ugxininiso oluphezulu ngokugqithisileyo lwezinto eziqinileyo kwisondlo.

Isixhobo kunye ne-automation inokunceda abaqhubi bagcine ulawulo ngokufumanisa imiba enjalo ngexesha langempela. Ngaphandle kwemilinganiselo ye-inline, i-tank-based instrumentation efana ne-ultrasonic bed level probes inokubonelela ngengqiqo ebalulekileyo. Ezi "diver" probes zinyuka zisehla ngaphakathi kwetanki, zichaza amanqanaba odaka, iindawo zokuhlala, kunye nokucaca okuphuphumayo. Imilinganiselo yomgangatho webhedi ibaluleke kakhulu kwizicwangciso zokulawula ukujikeleza, ukuqinisekisa ukusebenza okufanayo.
