Definitions

  • the invention relates to a method for binding particulate waste, such as dusts, metal waste, fibers, paper waste or the like, to form solids.
  • Particulate wastes e.g. Filter dusts, which are particularly common in today's cleaning of flue gases, are e.g. bound with cement and water.
  • Metal dusts e.g. Grinding dusts are very difficult to use. In particular, metal dusts can no longer be smelted due to the small particle size. The same applies to other metal waste, e.g. small metal shavings.
  • Fibers such as Asbestos fibers which accumulate as waste, can only be transported with great safety precautions and can only be partially recycled.
  • Paper waste such as secret documents, old paper money withdrawn from circulation, check forms, securities or the like. should usually be made unusable immediately without transport. While such paper waste was usually burned in the past, this is often encountered today due to environmental regulations. Toxic exhaust gases also arise due to the special printer color. y *
  • DE-A-2.402.976, DE-A-2.444.420 and DE-A-2.539.195 disclose a method for recycling i.a. thermoplastic plastic waste known to be processed into a new material.
  • plastic wastes are mixed with more than 50 percent by weight of fillers in a mixer at elevated temperatures.
  • the fillers can be wood waste, asbestos, peat, sulfur, silica, sand, graphite, metal shavings, ash from waste incineration plants, waste from thermosetting plastics or the like. act.
  • the plastic is crushed in particle form so that it can be mixed with the fillers in the mixer.
  • the plastic is mixed with the other parts, it is converted into the plastic or liquid state by applying heat, the parts are mixed and connected under pressure.
  • the fillers optionally provided with a coating or be incorporated with the plastic waste into a mixer, there warmed up and depending on the plastic up to 400 * C discharged as a quasi-homogeneous paste from the mixer.
  • This paste can, for example, also be subjected to a further process step, such as extrusion, extrusion, calendering, pressing, injection molding or granulation, after cooling.
  • the shaping of the material in this last process step can, however, also be carried out if the material still has a pasty consistency at elevated temperature.
  • the forming can take place under low pressures.
  • the pasty mass can thus be pressed through a calibration nozzle and extruded to form a strand or a plate.
  • the wood chips are coated in a vacuum, i.e. the chips are pre-dried before they come into contact with the plastic waste.
  • Other fillers can also be used under a gas atmosphere.
  • the material can be gen kg / cm 2 to 30 kg / cm 2 are formed by pressing or by injection molding.
  • the material has a density of 0.8 kg / l to 2.5 kg / l.
  • a commercially available kneading mixer or an agitator with a heated housing can be used as a mixer for this known method.
  • This known method for recycling plastic waste is not only machine-intensive, but also very energy-intensive, i.e. not very cheap.
  • the invention has for its object to provide a process with which particulate wastes, such as dusts, metal wastes, fibers, paper wastes or the like, can be bound more cheaply and a better, in particular, reusable product can be obtained.
  • plastic waste is generally understood to mean organic carbon-containing liquids or solids. This can be solid plastic waste of any kind, but also paint sludge or other sticky, in particular organic sludge.
  • the particulate wastes, dusts, metal wastes, fibers, paper wastes or the like, and the plastic wastes, such as organic carbon-containing liquids or solids or the like, are introduced into the hopper of a screw press.
  • the components entered are intimately mixed in the screw press by the revolving end (s) and pressed very strongly in the process.
  • the pressure in the mixture can be up to 100 bar.
  • the mixture of particulate waste and plastic waste air mixed. During kneading in the screw press, this air is pressed out of the solid mixture, as a result of which the heat necessary for melting the plastic waste is generated.
  • the temperature in the screw press can be easily controlled in accordance with the plastic waste used.
  • the mixture is expediently kneaded in the screw press until essentially all, i.e. both that present in the particulate wastes and also the additionally added air and which got into the screw press during filling, are removed.
  • Liquids in particular thickened waste liquids, can also be added to the mixture in the screw press.
  • Liquids containing harmful substances are fed into the screw press.
  • the high heat in the screw press evaporates the liquid, especially water.
  • the evaporating liquid, especially if it is also harmful, can be collected and condensed when it escapes from the screw press.
  • the solid components are kneaded into the mixture.
  • 100 liters of liquid are mixed into a ton of solid mixture of particulate waste and plastic waste.
  • filter dusts from flue gas cleaning systems are used as particulate waste. These are integrated into the plastic so that they no longer come into contact with the environment. However, care should be taken to ensure that the plastic is resistant to corrosion.
  • the weight fraction of the plastic waste in the solid mixture is up to 30%, in particular about 15%. Since the screw press no premixer or the like. is pre-arranged, it is recommended that the plastic waste be added to the mixture in granular form.
  • the granules can have a diameter of 10 mm to 40 mm.
  • film waste can have an area of 2 mm * 2 mm. This results in a uniform mixture in the material emerging from the screw press.
  • the product emerging from the screw press which can be in the form of rods or pellets, can withstand pressures of up to 400 kg / cm 2 and, depending on the material used, has a density of up to 1.8 kg / ltr and more.
  • the pellets or rods can have a cross section of, for example, 60 * 60 mm 2 .
  • pellets or bars can be stored as such. However, they can also be combined into larger blocks and sprayed with plastic. As such, they can also e.g. can be used as building materials.
  • pellets or staijgen also contain metallic materials, they can also be smelted in a metallurgical plant. Because of the high temperatures prevailing there, the non-metallic substances burn. The heat generated can be used for the smelting process.
  • the screw press can e.g. have an education as described in WO-A-83/03. 99, DE-A-3.714.508, DE-A-3.714.509 and DE-A-3.714.518. It is a screw press with two screws arranged parallel to each other.
  • the particulate waste arrives e.g. from a storage container onto a conveyor belt on which they are weighed. Depending on the weight of this waste and the dosage ratio, the plastic waste is dosed onto the conveyor belt. Both types of waste are introduced together into the receiving funnel of the screw press.

Abstract

Les déchets particulaires sont mélangés à des déchets plastiques dans une extrudeuse à vis, puis comprimés et extrudés. Les déchets particulaires et les déchets plastiques sont introduits dans la trémie d'alimentation d'une extrudeuse à vis. Les constituants introduits sont intimement mélangés dans l'extrudeuse par la ou les vis en rotation et ainsi très fortement comprimés. La pression dans le mélange peut alors atteindre 100 bars. Les déchets particulaires sont incorporés par liaison dans la matière plastique d'une manière qui empêche tout autre contact avec l'environnement.
