Udaka Lwamanzi Amalahle
I. Izakhiwo Nemisebenzi Yomzimba
I-slurry yamanzi amalahle iyi-slurry eyenziwe ngamalahle, amanzi kanye nenani elincane lezithasiselo zamakhemikhali. Ngokwenhloso, i-slurry yamanzi amalahle ihlukaniswe ibe yi-fuel ye-slurry yamanzi amalahle egxilile kakhulu kanye ne-slurry yamanzi amalahle ukuze kufakwe igesi esithandweni saseTexaco. I-slurry yamanzi amalahle ingapompa, i-atomized, igcinwe futhi ishiswe futhi ishiswe esimweni esizinzile. Cishe amathani amabili e-slurry yamanzi amalahle angathatha indawo yethani elilodwa lamafutha kaphethiloli.
I-slurry yamanzi amalahle yokushisa isebenza kahle kakhulu ekushiseni okuphezulu, ukonga amandla kanye nezinzuzo zemvelo, okuyingxenye ebalulekile yobuchwepheshe bamalahle ahlanzekile. I-slurry yamanzi amalahle ingathuthwa amabanga amade ngokuthuthwa ngepayipi ngotshalomali oluphansi kanye nezindleko zokusebenza eziphansi. Ingashiswa ngqo ngaphandle kokuphelelwa amanzi ngemva kokufika esiphelweni, futhi inqubo yokugcina nokuthutha ivaliwe ngokuphelele.
Amanzi azobangela ukulahlekelwa ukushisa futhi awakwazi ukukhiqiza ukushisa enqubweni yokusha. Ngakho-ke, ukugcwala kwamalahle kufanele kufinyelele ezingeni eliphezulu -- 65 ~ 70% ngokujwayelekile. Ukwengezwa kwamakhemikhali cishe ku-1%. Ukulahlekelwa ukushisa okubangelwa amanzi kubangelwa cishe u-4% wenani lama-calorific le-slurry yamanzi amalahle. Amanzi ayizinto eziluhlaza ezingenakugwenywa ekufakweni kwegesi. Kusukela kulo mbono, ukugcwala kwamalahle kungancishiswa ku-62% ~ 65%, okungase kubangele ukwanda kokusha komoya-mpilo.
Ukuze kube lula ukusabela kokusha kanye nokwakheka kwegesi, i-slurry yamanzi amalahle inezidingo ezithile zokwakheka kwamalahle. Umkhawulo ophezulu wosayizi wezinhlayiya ze-slurry yamanzi amalahle ukuze kube uphethiloli (usayizi wezinhlayiya onesilinganiso sokudlula esingaphansi kuka-98%) ngu-300μm, kanti okuqukethwe okungaphansi kuka-74μm (200 mesh) akungaphansi kuka-75%. Ubukhulu be-slurry yamanzi amalahle ukuze kube ukwakheka kwegesi buqinile kancane kunobo be-slurry yamanzi amalahle ukuze kube uphethiloli. Umkhawulo ophezulu wosayizi wezinhlayiya uvunyelwe ukufinyelela ku-1410μm (14 mesh), kanti okuqukethwe okungaphansi kuka-74μm (200 mesh) kungu-32% kuya ku-60%. Ukuze kube lula ukupompa i-slurry yamanzi amalahle futhi i-atomize, i-slurry yamanzi amalahle nayo inezidingo zokugeleza.
Uma izinga lokushisa legumbi kanye nezinga lokugunda elingu-100s, i-viscosity ebonakalayo ngokuvamile iyadingeka ukuthi ingabi ngaphezu kuka-1000-1500mPas. I-slurry yamanzi amalahle esetshenziswa ekuthuthweni kwepayipi elikude idinga i-viscosity ebonakalayo engabi ngaphezu kuka-800mPa·s ngaphansi kwezinga lokushisa eliphansi (izinga lokushisa eliphansi kakhulu lonyaka lamapayipi agqitshwe ngaphansi komhlaba) kanye nezinga lokugunda elingu-10s-1. Ngaphezu kwalokho, kuyadingeka futhi ukuthi i-slurry yamanzi amalahle ibe ne-viscosity ephansi uma isesimweni sokugeleza, okulula ukusetshenziswa; uma iyeka ukugeleza futhi isesimweni sokungaguquguquki, ingabonisa i-viscosity ephezulu ukuze kube lula ukuyigcina.
Ukuzinza kodaka lwamanzi amalahle ngesikhathi sokugcina nokuthutha kubaluleke kakhulu, ngoba udaka lwamanzi amalahle luyingxube yezigaba eziqinile neziwuketshezi, futhi kulula ukuhlukanisa okuqinile noketshezi, ngakho-ke kuyadingeka ukuthi kungabikho "imvula eqinile" ekhiqizwa ngesikhathi sokugcina nokuthutha. Lokho okubizwa ngokuthi "imvula eqinile" kubhekisela ekungeneni okungenakubuyiselwa esimweni sako sokuqala ngokushukumisa udaka lwamanzi amalahle. Amandla odaka lwamanzi amalahle okugcina ukusebenza kokungakhiqizi imvula eqinile kubizwa ngokuthi "ukuzinza" kodaka lwamanzi amalahle. Udaka lwamanzi amalahle olunokuqina okubi luzothinta kakhulu ukukhiqizwa uma imvula ivele ngesikhathi sokugcina nokuthutha.
II. Ukubuka Konke Kobuchwepheshe Bokulungiselela Udaka Lwamalahle Namanzi
Udaka lwamanzi amalahle ludinga ukugcwala kwamalahle okuphezulu, usayizi wezinhlayiya ezincane, ukugeleza okuhle, kanye nokuqina okuhle ukuze kugwenywe imvula eqinile. Kuzoba nzima ukuhlangabezana nazo zonke lezi zakhiwo ezingenhla ngesikhathi esisodwa, ngoba ezinye zazo zinqunyelwe ngokulinganayo. Isibonelo, ukwandisa ukugcwala kuzokwenza ukugeleza kwande futhi ukugeleza kwawo kunciphe. Ukugeleza okuhle kanye nokugeleza okuphansi kuzokwenza ukuzinza kube kubi kakhulu. Ngakho-ke, kubalulekile ukuqapha ukugcwala ngesikhathi sangempela.I-Lonnmeterimitha yobuningi ephathwa ngesandlainokunemba okufika ku-0.003 g/ml, okungafinyelela ukulinganiswa kobuningi obunembile futhi kulawule ngokunembile ubuningi be-slurry.
1. Khetha Ngokufanele Amalahle Aluhlaza Okusebenzisa Ukupompa
Ngaphezu kokuhlangabezana nezidingo zabasebenzisi abasezansi komfula, ikhwalithi yamalahle okugaya kumele futhi inake izakhiwo zawo zokugaya - ubunzima bokugaya. Amanye amalahle kulula ukuwakha i-slurry yamanzi amalahle agxilile kakhulu ngaphansi kwezimo ezijwayelekile. Kwamanye amalahle, kunzima noma kudinga inqubo yokugaya eyinkimbinkimbi kakhulu kanye nezindleko eziphakeme ukwenza i-slurry yamanzi amalahle agxilile kakhulu. Izakhiwo zokugaya zezinto zokusetshenziswa zokugaya zinomthelela omkhulu ekutshalweni kwezimali, izindleko zokukhiqiza kanye nekhwalithi ye-slurry yamanzi amalahle yesitshalo sokugaya. Ngakho-ke, umthetho wezakhiwo zokugaya amalahle kufanele uqondisiswe, futhi amalahle aluhlaza okugaya kufanele akhethwe ngokwezidingo zangempela kanye nezimiso zokusebenziseka kobuchwepheshe kanye nokucabanga kwezomnotho.
2. Ukuhlolwa kwamagredi
I-slurry yamanzi amalahle ayidingi nje kuphela usayizi wezinhlayiya zamalahle ukuze ifinyelele ubuncane obucacisiwe, kodwa futhi idinga ukusatshalaliswa okuhle kosayizi wezinhlayiya, ukuze izinhlayiya zamalahle ezinobukhulu obuhlukene zikwazi ukugcwalisana, zinciphise izikhala phakathi kwezinhlayiya zamalahle, futhi zifinyelele "ekusebenzeni kahle kokuhlanganisa". Izikhala ezimbalwa zinganciphisa inani lamanzi asetshenziswayo, futhi kulula ukwenza i-slurry yamanzi amalahle enokugxila okuphezulu. Lobu buchwepheshe ngezinye izikhathi bubizwa ngokuthi "ukulinganisa".
3. Inqubo yokudonsa kanye nemishini
Ngaphansi kwezici zobukhulu bezinhlayiya zamalahle ezingavuthiwe kanye nezimo zokugaywa, indlela yokwenza ukusatshalaliswa kobukhulu bezinhlayiya zomkhiqizo wokugcina we-slurry yamanzi amalahle kufinyelele "ekusebenzeni kahle kokuhlanganisa" okuphezulu kudinga ukukhetha okunengqondo kwemishini yokugaya kanye nenqubo yokugaya.
4. Ukukhetha Izithasiselo Ezifanisa Ukusebenza
Ukuze i-slurry yamanzi amalahle ifinyelele ukuhlushwa okuphezulu, i-viscosity ephansi, kanye ne-rheology enhle kanye nokuzinza, inani elincane lama-chemical agents, abizwa ngokuthi "izithasiselo", kumele kusetshenziswe. Ama-molecule esithasiselo asebenza ekuxhumaneni phakathi kwezinhlayiya zamalahle namanzi, anganciphisa i-viscosity, athuthukise ukusabalala kwezinhlayiya zamalahle emanzini, futhi athuthukise ukuzinza kwe-slurry yamanzi amalahle. Inani lezithasiselo ngokuvamile liyi-0.5% kuya ku-1% yenani lamalahle. Kunezinhlobo eziningi zezithasiselo, futhi ifomula ayizinzile futhi kumele inqunywe ngocwaningo lokuhlola.
