Abstract:

The present invention concerns a method and an equipment for pre-treatment of used tires () before a pyrolysis process. The invention is characterized in that said cleaning of each tire () is carried out in a closed chamber () with high pressure air jets. Air contaminated with dust and other dirt particles from said tire () is preferably continuously conducted through an air cleaning device () for removing said dust and other dirt particles from the air, and received cleaned air is fed to a high pressure blower () for producing said high pressure air jets.

Abstract:

Method and apparatus for biologically oxidizing organic matter. Finely powdered organic matter is suplied into the top end of an upright, high reaction vessel (). The vessel () has been filled up substantially completely by small balls, on the surfaces of which the matter to be oxidized is present in thin layers. By means of a conveyor () outside the vessel, the balls are transferred uppwards, whereby the balls in the reaction vessel () flow downwrds. Oxidizing air is blown uppwrds against the flow of balls, whereby in the upper section of the vessel, drying takes place in the first instance and then is formed an oxidizing zone automatically by microbial activity in a section, wherein the best oxidizing conditions are prevailing. Exhaust air is cleaned by means of ionic cleaners () and singlet oxygen generators () and oxidized matter is recovered from the bottom end of the reaction vessel.

Abstract:

The invention relates to a method and apparatus for removing impurities from waste water by electroflotation. The waste water to be cleaned is conducted through an electrolytic cell. Electrolysis is performed between two electrodes () of different electronegativities, such that the more electronegative electrode (), which is non-wearing in a cleaning process, is used for producing hydrogen gas and hydroxyl ions from water. The less electronegative electrode (), which is an active, wearing electrode in a cleaning process, is used for producing metal ions in a solution to be cleaned. In addition to this basic reaction, a desired oxidation-reduction reaction is initiated in the cell in a strictly controlled electric field for removing one or more designated impurities from cleaned water.
