Isingeniso
Emisebenzini yezimboni neyezemvelo, uketshezi oluningi olubalulekile aluhlanzekile neze—cabanga ngamanzi angcolile agcwele udoti, amatshe okumba agcwele indle, noma ukungcola kwezimboni okuqukethe izinto eziqinile ezilengayo. Kulawa “manzi angcolile,” ama-flowmeter endabuko avame ukwehluleka: amamitha omshini ayavaleka, amadivayisi e-ultrasonic alwa nokuphazamiseka kwesignali, kanye nezinzwa eziphazamisayo zingcola ngokushesha. Yilapho i-Doppler flowmeters ikhanya khona. Ukusebenzisa umphumela we-Doppler—lapho amagagasi omsindo egxuma khona ezinhlayiyeni ezihambayo oketshezini ukuze abale ijubane—lawa madivayisi aguqula inselele (izinto eziqinile ezilengayo) ibe yinzuzo. Ngokungafani namamitha avamile abheka ukungcola njengesivimbelo, ama-flowmeter e-Doppler athembele kukho, okwenza kube yisinqumo esithandwayo sokulinganisa ukugeleza kwezinye zezindawo ezimanzi eziqinile nezingcolile kakhulu. Kusukela ekuphathweni kwamanzi angcolile kamasipala kuya emisebenzini yokumba, aletha idatha ethembekile, yesikhathi sangempela egcina izinqubo zisebenza kahle, zithobela imithetho, futhi zingabizi kakhulu.
Kungani ama-Doppler Flowmeters ephumelela kakhulu kuma-Dirty Liquids
Imfihlo yempumelelo yama-flowmeter e-Doppler ngoketshezi olungcolile itholakala ekusebenzeni kwawo okuyingqayizivele kanye nomklamo wawo. Ngokungafani nama-flowmeter e-ultrasonic alinganisa ukugeleza ngokudlulisa amaza omsindo ngoketshezi (okuphazamiseka kalula yizinto eziqinile), amamodeli e-Doppler akhipha amaza omsindo avame kakhulu (ngokuvamile angu-0.5-2 MHz) aqondisa izinhlayiya ezilengayo, amabhamuza, noma imfucumfucu kuketshezi. Lapho la maza eshaya izinhlayiya ezihambayo, imvamisa yawo iyashintsha—lokhu kushintsha, okulinganiswa yinzwa yemitha, kuhambelana ngqo nejubane loketshezi. Njengoba ukuba khona kwezinto eziqinile kuyadingeka ukuze kufundwe kahle, uketshezi olungcolile aluyona inkinga kodwa luyimfuneko, kuqedwe izinkinga zokuvaleka nokungcola ezihlupha amanye amamitha.
Enye inzuzo ebalulekile ukwakheka kwawo okungaphazamisi noma okungaphazamisi kakhulu. Ama-flowmeter amaningi e-Doppler ayabamba: anamathela ngaphandle epayipini, ngaphandle kwezinzwa eziphuma oketshezini. Lokhu kusho ukuthintana noketshezi olubolayo, oluhlaselayo, noma olungcolile—akukho izingxenye okufanele ziguge, akukho ukuvuza okungaba yingozi, futhi asikho isidingo sokuvala uhlelo lokufakwa noma ukulungiswa. Isibonelo, epayipini lendle elithwala ukungcola kanye nemfucuza yemvelo, imitha ye-Doppler ebambayo igwema ingozi yokuvinjelwa kwezinzwa okungenza imitha ye-turbine ephazamisayo ingasebenzi. Ngisho namamodeli e-Doppler ohlobo lokufakwa (asetshenziselwa amapayipi amakhulu) anezinzwa eziqinile, ezimboziwe ezimelana nokuguguleka kanye nomonakalo wamakhemikhali, okuqinisekisa ukuhlala isikhathi eside ezimweni ezinzima.
Ngaphezu kwalokho, ama-flowmeter e-Doppler anikeza ukuhambisana okubanzi nezinhlobo zoketshezi ezingcolile. Aphatha konke kusukela emanzini angcolile (ngokuqukethwe okungu-1-5% kwezinto eziqinile) kuya kuma-slurry okumba (kufika ku-40% wezinto eziqinile), uketshezi oluqinile njengamanzi angcoliswe uwoyela, ngisho noketshezi olunamabhamuza egesi (isb., amanzi angcolile angenawo umoya). Ukunemba kwawo (ngokuvamile okungu-±2-5% kokufundwa) kuhlala kufana kuzo zonke lezi zinto eziketshezi ezihlukahlukene, kudlula amanye amamitha adinga uketshezi oluhlanzekile nolufanayo ukuze lusebenze kahle.
Izicelo Zangempela Ezimweni Ezingcolile Zoketshezi
Ukuthembeka kwama-Doppler flowmeters koketshezi olungcolile kuwenze abaluleka kakhulu emikhakheni eminingi, okuxazulula izinselele zokulinganisa esezinesikhathi eside.
Ukwelashwa Kwamanzi Angcolile Kamasipala
Izitshalo zamanzi angcolile ziwumsebenzisi oyinhloko wama-flowmeter e-Doppler, lapho ziqapha khona ukugeleza kwamanzi angcolile angaphekiwe, udaka olusebenzayo, kanye nokungcola okulungisiwe—konke kugcwele izinto eziqinile, izinto eziphilayo, kanye nemfucumfucu. Endaweni yokungena, amamitha e-Doppler alinganisa ukugeleza kwamanzi angcolile angaphekiwe ukuze kuthuthukiswe umthamo wokwelapha wesitshalo, kuqinisekiswe ukuthi akukho ukulayisha ngokweqile. Emathangini okungenisa umoya, alandelela ukugeleza kodaka olusebenzayo (ingxube ebanzi, egcwele amagciwane) ukuze kugcinwe amazinga afanele e-oxygen, abalulekile ekuhlukaniseni ukungcola. Ngokungafani namamitha omshini avala udaka, amamodeli e-Doppler asebenza kahle, enciphisa isikhathi sokungasebenzi kokulungisa futhi aqinisekise ukuhambisana nezindinganiso zokukhipha indle endaweni ezungezile.
Ukumbiwa Nokucubungula Amaminerali
Imisebenzi yokumba ikhiqiza inani elikhulu lama-slurry—izingxube zamanzi kanye ne-ore echotshoziwe, isihlabathi, noma i-tailings (izinto ezilahliwe). Ukulinganisa ngokunembile ukugeleza kwe-slurry kubalulekile ekwenzeni ngcono ukubuyiswa kwamaminerali nokuphatha imfucuza. Ama-Doppler flowmeter ahamba phambili lapha: aphatha ama-slurry ahlasela kakhulu (anezinhlayiya ezifika kumamilimitha amaningana ngobukhulu) angabhubhisa amanye amamitha. Isibonelo, ekumbeni ithusi, amamitha e-Doppler alandelela ukugeleza kwama-slurry e-ore kuya emathangini okuntanta, lapho amakhemikhali ahlukanisa khona ithusi nemfucuza. Ekuphatheni ama-slurry, aqapha ukugeleza kwama-slurry emachibini okugcina, avimbele ukugcwala kanye nomonakalo wemvelo. Umklamo wawo ongaphazamisi uphinde ugweme ukungcoliswa kwe-slurry, okuyinkinga ebalulekile yokuhlanzeka kwamaminerali.
Ukukhiqiza Izimboni
Izinqubo eziningi zokukhiqiza zikhiqiza ukungcola okungcolile okudinga ukulinganiswa okunembile kokugeleza. Ekucubungulweni kokudla, isibonelo, amamitha e-Doppler aqapha ukugeleza kwamanzi angcolile aqukethe izinsalela zokudla, uwoyela, kanye nensipho—uketshezi oluzovimba amamitha endabuko. Ekukhiqizeni amakhemikhali, alinganisa ukugeleza koketshezi olubolayo oluxutshwe nemikhiqizo eqinile (isb., ama-pellet epulasitiki ekukhiqizweni kwe-polymer), ukuqinisekisa ukulahlwa okuphephile kanye nokuhambisana nemithethonqubo yemfucuza. Emishinini yokugaya i-pulp kanye nephepha, alandelela ukugeleza kotshwala obumnyama (umkhiqizo oqinile, ocebile ngamakhemikhali womshini wokugaya izinkuni), esiza imishini yokugaya ukuthola amandla otshwaleni ngenkathi igwema umonakalo wemishini.
Ukwakha kanye nobunjiniyela bokwakha
Izindawo zokwakha zivame ukubhekana namanzi angcolile avela ekumbiweni, ekuhlanzweni ngokhonkolo, noma ekugelezeni kwamanzi emvula (agcwele indle). Ama-Doppler flowmeter asetshenziselwa ukukala ukugeleza kwalawa manzi kuya ezinhlelweni zokwelashwa (isb., amathangi okufaka indle) ngaphambi kokukhishwa, ukuqinisekisa ukuhambisana nemithetho yendawo yemvelo evimbela amanzi agcwele indle ukuthi angene emifuleni yamanzi yemvelo. Ukuphatheka kwawo—amamodeli amaningi asebenza ngebhethri futhi kulula ukuwafaka okwesikhashana—kuwenza afaneleke kakhulu ezindaweni zokwakha, lapho ukugeleza kuvame ukuba okwesikhashana futhi izindawo zishintsha njalo.
Imiklamo Ekhethekile Yezimo Ezingcolile Kakhulu Zoketshezi
