Abstract
Methods of coal cleaning in autogenous suspension, in Parnaby drum and hydrocyclones are, in recent years, getting more and more importance in countries of the former Yugoslavia (Serbia, Montenegro, Republika Srpska). The coal cleaning process has proven to be effective, especially for younger coals; it is quite simple, and in addition to that it is acceptably priced. As products of this process, obtained are clean coal (CC) sized -100(80)+0.5 mm, has tailings fractions of -100(80)+0.5 mm and sludge fractions of -0.5+0 mm. The treatment of sludge in the past (typically) involved its settling in the sedimentation facilities and discharge of the overflow water into the watercourses. The latest trends which are in full compliance with environmental requirements imply different treatment of sludge from the Parnaby process. This treatment usually includes thickening and filtering of sludge with return of the overflow water from the thickeners back into the process, in the so-called closed cycle. | Apstrakt
Postupak čišćenja uglja u atogenoj suspenziji u Parnaby bubnju i hidrociklonima poslednjih godina dobija sve više na zančaju u zemljama bivše Jugoslavije (Srbija, Crna Gora, Republika Srpska). Ovaj postupak čišćenja uglja pokazao se kao efikasan pogotovu za mlađe ugljeve, dosta je jednostavan, a uz to je i cenovno prihvatljiv. Kao proizvodi ovog procesa javljaju se čist ugalj (ČU) krupnoće -100(80)+0,5 mm, jalovina krupnoće -100(80)+0,5 mm i mulj krupnoće -0,5+0 mm. Tretman ovog mulja u prošlosti je podrazumevao (po pravilu) taloženje u taložnicima sa ispuštanjem prelivne vode u vodotokove. Najnovije tendencije, koje su u potpunosti u skladu sa ekološkim zahtevima, podrazumevaju drugačiji tretman mulja iz Parnaby procesa. Ovaj tretman najčešće podrazumeva zgušnjavanje i filtriranje mulja uz vraćanje prelivne vode iz zgušnjivača u tzv "zatvoreni ciklus". |
