Abstract: A method and apparatus for treating mixed waste by pyrolysis. Organic mass is carbonized by heating to carbon in a pyrolysis reactor (3) in an oxygen-free environment. Pyrolysis gases are distilled for oil and the gases are used for energy production. Solid matter resulting from pyrolysis is sieved for separating inorganic coarse particles from a carbon fraction. The carbon fraction is milled in two operations, first with a roller mill (8) and then with a jet mill (10), a removal of metal being performed between the operations. The pulverized carbon fraction is classified by means of ionizing particle separators (11, 12, 13). The multi-stage particle separation is followed by discharging clean air and recovering fine carbon.

Abstract: The invention refers to an ion particle classifier and a method for classifying coarse solid particles from an air suspension of micronized particles, said ion particle classifier comprising a housing surrounding an electrically conductive, cylindrical inner layer, acting as a first electrode, and a centrally positioned rod with a number of radially directed lips, acting as a second electrode, said electrodes being electrically insulated from said housing and coupled to a high voltage current source, an inlet pipe for said air suspension of micronized particles to be classified terminates at a one end of said first electrode and an outlet pipe for an air suspension of classified line particles is mounted close to the opposed and of said first electrode, one end of said is provided with discharge means for a fraction of classified coarse particles of said air suspension, said classifier further being provided with a rinsing air input entering said classifier at one of its ends.

Abstract: The present invention refers to a method and an equipment for pyrolytic treatment of organic material comprising a supply storage receiving the organic material to be treated, a number of containers with meshlike walls, each to be charged with a batch of said organic material, a horizontal reactor with a charge gate in one end and a discharge gate in the opposite end, the interior of the reactor being divided by means of internal gates into at least a heating chamber, a pyrolysis chamber, and a cooling chamber, as well as a recovery storage for a solid pyrolytic residue of the organic material, i.e. the pyrolytic coke, the pyrolysis chamber being provided with an outlet pipe for generated pyrolytic gas terminating in a fractionating condenser, said condenser being provided with an outlet for each liquid fraction and an outlet pipe for uncondensed pure pyrolytic gas, which outlet pipe terminates in a gas tank.

Abstract: The invention concerns a micronizing device comprising a grinding housing with an outlet opening at one end, two coaxially positioned rotatably driven hollow axles entering the grinding house through two opposite side walls thereof, each of said axles having an inner end provided with a conically enlarging disc defining a grinding chamber, a circumferential outlet gap being formed between said discs, each disc being provided with at least one concentrically positioned ring of axially directed taps or wings near the circumference of the disc, the rings having different diameters, so that said discs can be driven to rotate in opposite directions, two acceleration nozzles are brought into the grinding chamber through the hollow axles, said nozzles being directed towards a common point in the grinding chamber away from a center point of said grinding chamber. The invention concerns also a method using said device.

Abstract: A flock separating apparatus, has an electrolytic cell (2) fitted with iron electrodes and a separating tank (3), wherein the flock is carried upwards by a hydrogen gas produced in electrolysis. The separating tank (3) has a substantially vertical pipe having a length which is at least 10 times, preferably at least 15-20 times more than its diameter.
