Definitions

  • the invention relates to a reactor for gasifying biomass, in particular wood, having a filling shaft and an ash bed arranged below the filling shaft.
  • the invention relates to a fine filter for cleaning a product gas generated from biomass.
  • the invention relates to a use of such a fine filter.
  • the invention relates to a process for the gasification of biomass in a reactor, in particular in a reactor of the type mentioned, to a product gas.
  • Biomass gasifiers are known as such from the prior art.
  • a device is known, gasified with the biomass such as wood, straw or biological waste in a reactor and a resulting gas is then passed into a gas-powered engine, where this gas
  • Combustion is converted into mechanical energy.
  • the motor is connected to a generator, which converts the mechanical energy into electrical energy.
  • the object of the invention is to overcome or reduce the disadvantages of the prior art by providing a reactor with which a more efficient method is possible. In addition, a fine filter is to be specified, which further increases the efficiency of such a method.
  • the aim is further to specify a use of such a fine filter.
  • the first object is inventively achieved in that in a reactor of the type mentioned a device is provided, with the biomass adhering to the hopper is solvable and / or a heat exchanger is provided, with a produced from the biomass product gas heat tracked in the hopper
  • the heat exchanger with which the heat of the product gas can be transferred to the biomass in the hopper and the oxidation air in particular also has the advantage that an energy required for pyrolysis and preheating the oxidation air can be taken from the product gas, so less Energy must be taken from the biomass and a temperature of the
  • Product gases can be reduced. If the product gas in one
  • the multiple jacket is formed such that it has a plurality of approximately cylindrical, approximately concentric coats, between a first jacket, which forms the hopper, and a second jacket, which encloses the first jacket, product gas in a preferred vertical installation due to thermal buoyancy can flow from bottom to top and around this second jacket, a third jacket is arranged such that the area between the second jacket and the third jacket of the oxidizing air can be flowed through. In this way, heat transfer from the product gas via the first jacket or biomass in the feed chute and over the second mantle to oxidation air can take place and the temperature of the product can be increased
  • the first jacket which on the one hand borders the biomass and, on the other hand, the product gas, preferably consists of temperature- and acid-resistant material, for example an austenitic chromium-nickel-molybdenum steel.
  • the second jacket adjacent to the oxidizing air as well as to the product gas is preferably made only in a lower region of heat-resistant steel and in an upper region of a normal boiler plate in order to minimize manufacturing costs. It is advantageous if an insulating layer of a heat-insulating material is applied to the third jacket, which is preferably also made of steel, in order to prevent heat from the oxidizing air from being emitted to an environment.
  • the hopper can be added by means of the vibrator vibrated.
  • the vibrator may consist of a motor and an imbalance or other electromagnetic associated with the motor or mechanical devices, oscillations of the vibrating device are preferably transferable by means of molding tubes to the hopper. These forming tubes can form a direct connection between the vibrator and the hopper; but it can also be provided that the vibrator is connected indirectly via flexible connecting elements with the hopper.
  • the connection between vibrator and hopper is preferably designed such that temperature-induced mechanical stresses throughout the reactor are minimized and a tightness of the hopper is permanently guaranteed.
  • the vibrator is activated at regular intervals between 10 and 30 minutes, preferably between 15 and 25 minutes, more preferably about 20 minutes for a few seconds, preferably for about 5 seconds.
  • the wedge slide preferably comprises a slide plate, which is guided linearly movable in a groove of a frame rigidly connected to the feed chute.
  • the wedge slide and the frame are preferably components of a lock over which the biomass the
  • connection of the slide plate with the frame is preferably carried out particularly wear with one or more ball bearings. Other types of storage are possible. Due to an acidic atmosphere in the
  • Hopper is the entire wedge slide or parts thereof in an acid-resistant material, preferably an acid-resistant steel executed. It is advantageous that a sealed feed device is provided, with which the biomass can be fed to the feed chute in the absence of oxygen. This is particularly important, therefore, in order to prevent unwanted gases, in particular oxygen, from entering the feed chute in order to be able to trigger chemical reactions in the feed chute in a targeted manner, that of a controlled or controlled one

  • the feed chute is tapered in a lower region, in particular with a ratio of one
  • Chute cross section measured in a cylindrical upper portion of the hopper and the fire zone cross section in a fire zone. Since the biomass changes its volume as it moves through the lower part of the pyrolysis that takes place in this lower region, it is advantageous if the hopper is adapted to a volume change of the biomass, to ensure a uniform flow velocity of the biomass and optimal conditions for the running chemical To enable processes.
  • a cone angle between a cone axis and a lateral surface of the conical lower region is between 20 ° and 60 °, more preferably between 30 ° and 50 °, in particular about 40 °.
  • the fire zone adjoining this conical region is preferably cylindrical
  • a lower region between the fire zone and a constriction, which further adjoins the fire zone is preferably likewise conical, in order to constructively take into account the volume change of the biomass even in this lowermost region.
  • a cone angle of this lowermost region is preferably between 20 ° and 60 °, more preferably between 30 ° and 50 °, in particular about 40 °. This cone angle can also correspond to the cone angle of the lower region.
  • an oxidation air supply is connected via an intermediate region and an oxidation air ring with oxidation air nozzles, which open into a fire zone.
  • the oxidation air can be preheated both in the intermediate region, which is preferably thermally connected to a product gas region, and in the oxidation air ring, which is preferably thermally connected to the fire zone. This preheating the oxidation air is made particularly favorable. Another advantage can also be seen in the fact that the oxidation air can occur evenly over a circumference of the fire zone in this and thus can be evenly distributed in the fire zone.
