Definitions

  • the invention relates to a device for comminution and drying of waste materials, slags, rocks and the like materials according to the preamble of patent claim 1.
  • Waste and the like materials are still often disposed of in landfills. Since landfills have only a limited uptake capacity, it is desirable to comminute the waste before it is deposited. However, the comminution of the waste materials can also be used for treatment for the generation of energy by a subsequent combustion or degassing plant. By crushing waste materials or pulverizing slags and rocks, such as ore stones, valuable raw materials can be separated and recovered more easily.
  • a known problem in the treatment of waste materials such as municipal waste, industrial sludges such as cement, lime industry and sewage sludge is the relatively high moisture content often associated with these wastes. This moisture content, which is usually difficult to separate from the waste materials, is a problem that should not be underestimated in landfills as landfill water.
  • the high moisture content leads to a lower calorific value of the waste material used.
  • the high moisture content in the waste and the material size generally have a negative impact on the energy and transport balance (C0 2 emissions).
  • the known from the prior art grinders or the like for the comminution of waste materials have a relatively poor efficiency and are not sufficiently suitable for a reduction of the moisture content.
  • Also known from the prior art is a milling apparatus which has a substantially funnel-shaped vessel with a cylindrical attachment. Compressed air is injected circumferentially into the cylindrical cap to create an air vortex within the funnel-shaped vessel. This known device requires up to 100 m 3 of compressed air per minute, which is a great disadvantage for the energy balance and for the efficiency of the device.
  • baffles divert the air in the circumferential direction of the boiler.
  • the material to be crushed is required via a feed line in the cylindrical attachment and exposed to the air vortex. In the air vortex, the introduced material is to be crushed.
  • the baffles also serve as baffles and are designed to protect the air inlets from swirling material around.
  • the crushed material sinks to the ground due to gravity and is discharged through an opening at the bottom of the funnel-shaped vessel.
  • a cylindrical chimney arranged at the opposite, larger diameter end of the boiler on the cylindrical top ensures removal of excess air.
  • the object of the present invention is therefore to provide a device for crushing and drying of waste materials, slags, rocks and the like materials, which takes into account the above-described disadvantages of the devices of the prior art.
  • the device should be less prone to wear and allow for sufficient size reduction, even pulverization, and / or drying of the waste used.
  • the device should be as uncomplicated as possible and have proven and structurally simple components, as well as inexpensive to manufacture and in operation.
  • the solution of these objects consists in a device for crushing and drying of waste materials, slags, rocks and the like materials, which has the features listed in claim 1. Further developments and advantageous and preferred embodiments of the invention are the subject of the dependent claims.
  • the invention proposes a device for crushing and drying waste materials, slags, rocks and the like materials, which comprises a substantially funnel-shaped vessel with a cylindrical attachment. At least two air inlets distributed over the circumference for introducing compressed and possibly heated air are arranged on the cylindrical attachment. The bottom of the funnel-shaped vessel is equipped with a discharge opening for crushed material. At the outlet opening against overlapping, larger diameter end of the boiler, an air outlet opening is arranged on the cylindrical attachment. A feeder for the material to be crushed opens into the cylindrical attachment. At each of the at least two air inlets distributed over the circumference of the cylindrical attachment, a supersonic nozzle with venturi system is arranged such that the supplied air can be introduced in the circumferential direction of the cylindrical attachment and the funnel-shaped vessel.
  • the supplied, preferably heated, air at the entry into the cylindrical attachment on the funnel-shaped vessel reaches very high flow velocities, which can achieve the scarf and can exceed it several times over. Characterized a heated air vortex is generated in the cylindrical attachment and in particular in the direction of its bottom funnel-shaped narrowing boiler.
  • the high flow rates are achieved by supplying the air under a pressure of about 4 6 bar. Depending on the altitude of the sea, the air volumes can reach about 30 to 50 mVmin. For example, these amounts of air can be generated and promoted by means of a controllable oil-free screw compressor.
  • a nozzle is understood as meaning, for example, a nozzle which has a cross-sectional profile corresponding to a Laval nozzle.
  • the formation of the supersonic nozzle as a Laval nozzle makes it possible to significantly reduce the required air consumption, for example by up to 50%. This has a great influence on a positive energy balance. Due to the high air velocities, the introduced materials are severely minced, even pulverized. As a result of the pulverization of the materials used, valuable raw materials contained in the materials can easily be returned to the industry. Due to the high degree of comminution, the loading capacity of transport facilities can also be utilized much better, which in turn can have a positive effect on the environment (reduction of C0 2 emissions).
  • the venturi system serves to "break up" the air vortex created by the supersonic jets.
  • the materials introduced into the air vortex do not withstand the forces that occur during sudden command and are therefore broken down into very small components petal idea, shear and friction forces, as well as negative pressure and cavitation support the comminution of the materials contained in the moisture, such as in sewage, - and industrial sludge contained and bound in the solid particles water is thereby separated and with the air in the vortex warming air through the
