Khetha ulimi:
ST Izinsiza kusebenza & ubuchwepheshe LLC (STET) uye wazakhela inoveli, lobunikazi electrostatic ibhande isihlukanisi oluye lwaboniswa phezu commercial ukuziphilisa ukucutshungulwa namaminerali ezimbonini kanye kabusha amalahle omlilo impukane umlotha.
Electrostatic ngokwahlukana ubuchwepheshe ibilokhu titadishwe 100 iminyaka. Empeleni, le enelungelo lobunikazi ukudla ukusetshenziswa lokuqala ngokuhlukana electrostatic kakolweni middlings sifakwe 1880. ucwaningo okuqhubekayo kanye nobuchwepheshe libonisa isithembiso ekudaleni ukubaluleka udoti ekusakazeni byproducts zokukhiqiza izinqubo zamanje, ezifana umkhiqizo kawoyela lwesitshalo noma lwesilwane (kuhlanganise inhlanzi) ukucutshungulwa.
Ngamafuphi nje, the STET isihlukanisi imisebenzi esekelwe umehluko ebusweni yokuthakwa kwamakhemikhali. Kwezinye izimo, lezi abahlukanisayo ebandleni bekungekhe kukghonakale usebenzisa ubukhulu kuyizinhlayiyana noma ukuminyana wedwa. separators STET sika ukusizakala "Tribo-ukushaja" (Bheka Umfanekiso 1) okuyinto eyenzeka ngokushesha ngaphakathi imishini.
Figure 2 sibonisa indlela izinhlayiya bondliwa lamachweba akhanga izivakashi eziningana okuphakelayo kule ndawo ngokuhlukana, okuyinto igebe phakathi electrode ovundlile (< 13mm [0.5"]). voltage (ngokuvamile 12kV) sisetshenziswa yonkana lokhu igebe ewumngcingo ukwakha inkambu eqinile kagesi. Izinhlayiyana sishukumiseleka ngokusebenzisa le izoni ukuhlukaniswa by iluphu nokuphathelene okuqhubekayo, evulekile anezikhala ibhande ezisebenza ngesivinini (4-20m / s [13-65ft / s]).
Ngaphakathi indawo ngokuhlukana, umklamo nokuphathelene we ezihambayo ngokushesha ibhande okuqhubekayo imisebenzi eziningana ngesikhathi esisodwa (Figure 3).
Idala okusezingeni eliphezulu omawala zone phakathi electrode, ukugqugquzela tribo-ukushaja. Lokhu umphumela kuyizinhlayiyana-to-kuyizinhlayiyana ukushayisana okuphindaphindiwe, ngokugcina izinto icala ngaphakathi isihlukanisi futhi isidingo i ngaphandle pre-ukushaja uhlelo. Okokugcina, ukuhamba ibhande libhubhisa izinhlayiya emihle kusukela electrode, nokugcina ukusebenza kwabo, futhi kusiza umkhiqizo ehlukile futhi lubangelwa iqoqo.
I STET tribo-electrostatic ibhande isihlukanisi uye wasibonisa ikhono "beneficiate" (ukuthuthukisa izindawo) ezihlukahlukene amaminerali fly umlotha emhlabeni wonke futhi uze wabonisa isicelo ukucutshungulwa inani elikhulayo ukudla okuphakelayo izinto.
Esinye isibonelo salokhu nge ukucutshungulwa whitefish Sakusihlwa okwakubekelwa okudayiswayo etholwe, nepepper, futhi lwahlolwa ngokusebenzisa umshayeli isikali yethu isihlukanisi ufanekiselwa Figure 4.
Ezenye
Uhlolo umshayeli yayiqhutshelwa ku 2 amathani okudayiswayo atholwe whitefish Sakusihlwa abangu nepepper ngaphambi processing ngokusebenzisa yethu isihlukanisi tribo-electrostatic. Imiphumela ye-whitefish Sakusihlwa abonisa amaprotheni nokunonophala nokwehlisa abalulekile umlotha e pass olulodwa, njengoba kukhonjisiwe lapha.
| Imiphumela yemishini yokuhlola | |||
|---|---|---|---|
| Okuphakelayo | E1 | E2 | |
| Isivuno esikhulu | 39.3% | 60.7% | |
| Umswakama | 2.5% | ||
| Ash | 12% | 6.1% | 15.2% |
| Amaphrotheni | 81.1% | 89.8% | 77.6% |
Ulwazi ekhasini elilandelayo uyalandisa umkhiqizo grade (njengoba angenze-misela by amaprotheni wt. %) ukuze isivuno mass.
Kungaba kuqashelwe kusukela lezi idatha kukhona ukuhweba phakathi kwemigomo ezimbili. Nokho, sakwazi sifinyelele 10% (isihlobo) ukwandisa amaprotheni futhi cishe kakhulu 50% umlotha nokuncipha ukusakaza umkhiqizo pass olulodwa, futhi ngaphandle nokwenza eminye.
usayizi Okuphakelayo kuyizinhlayiyana okokusetshenziswa kushintshwe ukucubungula ngendlela hammermill usayizi kuboniswe ekhasini elilandelayo.
Abahlukanisi be-STET bayakwazi ukufakelwa iningi izinto zokudla nezokudla cishe 10-15 MT ngehora (kuye ngokuthi kwabantu) kodwa kudle kuphela 3-4 kWh kagesi. Inqubo ivumela abahlukanisayo ukuba amanzi futhi amakhemikhali khulula, sasingeke sibe khona isidingo input ezishisayo kanye ukusakaza imfucuza elakhiwe.
Le ndlela ngokwahlukana kungaholela ukukhiqizwa ivolumu ephezulu, izinga okusezingeni izinhlanzi amaprotheni njengenhlangano isithako ekuphakeleni ukwakhiwa kusukela kwasolwandle ukucutshungulwa imfucuza.
Lokhu leyavela izinhlanzi ukucutshungulwa libonisa isithembiso ekuhlinzekeni amaprotheni namaminerali abalulekile kumngane noma ukuthengisa izilwane, ekusizeni ukusekela nesidingo esikhulayo amaprotheni wezokudla eliqhutshwa kwenani labantu.
