    摘要: Provided is a method for processing electronic and electrical device component scrap, which can accurately and efficiently sort electronic and electrical device component scrap. The method for processing electronic and electrical device component scrap includes a separation step of separating non-metal objects 1b or metal objects 1a1, 1a2 from electronic and electrical device component scrap 1 containing the metal objects 1a1, 1a2 and the non-metal objects 1b using a sorter 10 comprising a metal sensor 2, a color camera 3, an air valve 4, and a conveyor 5, wherein a fixed distance is provided between the metal objects 1a1, 1a2 adjacent to each other so as to prevent the non-metal objects 1b between the metal objects 1a1, 1a2 from being erroneously detected, when detecting the metal objects 1a1, 1a2 in the electronic and electrical device component scrap 1 by the metal sensor 2.

    摘要: The invention relates to a thermolysis system and method for obtaining recovered carbon black and fuel from disused tires, which includes a thermolysis reactor and a flash vessel acting jointly to refine fuel without the need for post-treatment to clean same. During thermolysis, condensers are cleaned without needing to cut the flow or deviate the gas stream, since the deposits formed inside tubes of a heat exchange system are cleaned using a part of the fuel obtained. The carbon black obtained is comparable to existing semi-reinforcing carbon blacks. The obtained fuel has a high content of aromatic compounds, and its carbon content is reduced to 3% by weight, up to 0.8% by weight, with respect to fuels obtained in pyrolytic processes, without requiring post-treatment such as distillation processes or catalytic treatment.

    摘要: A waste management system, primarily intended to be for waste floating in water, though it can also be used on land. A shredding device will reduce the size of the particles of waste. Ocean water is removed by a drying device. The dried waste material is cryogenically frozen using liquid nitrogen or other suitable means. The frozen waste material is then pulverized and ground into a powder. The powder may then be sprayed into a gas-filled chamber and heated. Temperature, pressure and humidity are maintained within the chamber for more than one minute. Microwave or other radiation and catalysts may be used to enhance the process of extraction. The processed material is then removed from the chamber. Carbon and water may be recycled. The carbon may be used as fuel by the ship. Water may also be used by the ship or returned to the ocean in a non-toxic condition.

    摘要: A method and apparatus for continuous magnetic filtration of ferrous mill scale from liquid solution employs a tank for receipt of fluids laden with mill scale. A curvate trough within the tank receives a rotatable magnetic drum and establishes a channel therebetween. An air compressor and associated manifold generate bubbles within the tank and adjacent the rotatable magnetic drum. The mill scale attaches to the bubbles, which are attracted to the surface of the drum where the mill scale accumulates. The accumulation of mill scale particles is moved about the surface of the rotating drum by a scraper proximate the surface thereof. By moving the accumulated mill scale particles to regions of the rotating drum that are of a magnetic force insufficient to retain them upon the surface of the drum, the mill scale particles are removed and passed to a conveyor system.

    摘要: A magnetic separator comprises: at least one pair of guide rolls; and a conveyor belt that extends between the pair of guide rolls, and conveys a powdery and/or granular material containing ferromagnetic particles, wherein one guide roll of the pair of guide rolls is a hollow roll, and includes, in a hollow part thereof, a magnet roll including a plurality of magnets that are arranged along an inner peripheral surface of the guide roll in lines at intervals so that different magnetic poles alternate in a circumferential direction, and the magnetic separator further comprises a shield wall that covers a circular arc region of an outer peripheral surface of the guide roll except a circular arc region around which the conveyor belt is wound, to block magnetic lines of force from the plurality of magnets.
