ST Helmets & Technology LLC (STET) e qapa bukeng, patented electrostatic lebanta kgaoganyo hore e se e ile a bontša ka khoebo-tekanyo e ka sebetsa oa liminerale liindasteri le ka botjha ha thepa ea mashala combustion e fofa molora.
Electrostatic thekenoloji karohano e se ithutile fetang 100 lilemo tse. Haele hantle, pele patented tšebeliso lijo tsa karohano electrostatic tsa middlings koro ile filed ka 1880. ho etsa lipatlisiso e tsoelang pele le theknoloji e bontša ka tsepiso ea hae ka ho bōpa boleng ho tloha litšila le molapo byproducts tsa dithulaganyo jwale ho hlahisoeng, tse kang ho hlahisoeng dimela oli kapa phoofolo (ho akarelletsa le tlhapi) sebetsa.
Ka mantsoe a mang, le STET kgaoganyo mesebetsi thehiloeng ho se tšoane ka k'hemistri holim. Maemong a mang, karohano tsena ne ba ke ke ha khoneha ho sebelisa phatsa boholo kapa segokanyipalo feela. separators STET e nka monyetla ka "Tribo-tjhaja" (sheba Figure 1) eo e hlaha ka potlako ka har'a thepa e.
Figure 2 e bontša kamoo likaroloana tse fepa ke e 'ngoe ea likou tse' maloa fepa ka ka libaka karohano, eo ke lekhalo pakeng tsa li-electrode tshekaletseng (< 13limilimithara [0.5"]). Palo ea li-volts (ka tloaelo ho 12kV) e sebelisoa ka mose lekhalo ena moqotetsane ho bopa e matla ea tšimo motlakase. Likaroloana susumelletseha ka libaka ena karohano ke dikhampani le tsoelang pele sekgoqetsane, bulehileng letlooeng lebanta sebetsa ka phahameng lebelo (4-20Mof [13-65feat / s]).
Ka hare ho libaka karohano, moralo dikhampani tsa ka potlako ho fallela lebanta e tsoelang pele o etsa mesebetsi 'maloa ka nako (Figure 3).
Ho etsa hore e phahameng loebehlanang libaka pakeng tsa li-electrode ho, kgothaletsa tribo-tjhaja. Sena se fella ho tloha pheta thulana phatsa-to-phatsa, ho boloka thepa e qosoa ka hare kgaoganyo le felisa ho hlokahala hore e ka ntle ho ea pele ho lefisa oona tsamaisong. Qetellong, motsamao oa lebanta la sweeps likaroloana tse molemo tse tsoang li-electrode, boloka tshebetso bona, le ntsetso-peleng sehlahisoa arohaneng le ka sehlahisoa pokello.
The STET tribo-electrostatic lebanta kgaoganyo o bontšitse matla a ho "beneficiate" (ntlafatsa thepa ya) mefuta e fapaneng ya le liminerale le fofa molora lefatšeng ka bophara 'me e bontša hore kopo bakeng sa sebetsa ea palo e eketsehang ea thepa le lijo le fepa ka.
Mohlala o mong oa sena ke le ho e lokisa ya tsa whitefish Lijo tseo ile ka mokhoa oa thekiso fumanweng, siloa, le lekoa ka rona kgaoganyo motsamaisi-tekanyo e tšoantšetsoang ka Figure 4.
