Definitions

  • the invention relates to a reactor for burning explosives and explosive objects.
  • Explosives are solid, plastic or liquid explosive substances, such as explosives, fuels and guns, igniters, igniters and pyrotechnic substances.
  • Explosive objects are objects that contain explosives and are intended to have an explosive, shooting or propelling effect, an ignition effect, an ignition effect or a pyrotechnic effect.
  • One of the explosive items is ammunition.
  • combustion should be understood to mean any oxidative reaction which the explosive enters into with the or additional oxygen contained in the explosive (also air-oxygen) after ignition with an open flame and which leads to the explosive losing its explosiveness .
  • a reactor for the combustion of waste materials in the form of a piercing reactor with an externally sealed reactor with a closed reaction space, with locks and with a series of cassettes for the material to be burned, the longitudinal be passed through the reactor.
  • the waste is first degassed by heating the container with an open flame and the smoldering gases formed are immediately ignited and burned in the presence of sufficient oxygen.
  • This reactor is not suitable for the combustion of explosives, since with external heat supply via the container walls a local exceeding of the deflagration temperature of the respective explosives cannot be avoided and in the presence of open flames the entire explosive inventory will react explosively at these temperatures.
  • Controlled combustion of explosives is only possible if the temperature of the explosive can be kept below the respective poisoning temperature during the combustion. This is usually the case with open combustion on the fire site. In the case of a closed reactor, this condition must be met by suitable technical measures. This can be achieved with the present invention.
  • the object of the invention is to provide a reactor which enables combustion with the least possible combustion gas removal with high operational reliability and while avoiding the uncontrolled release of combustion gases to the environment.
  • the reactor according to the invention consists, for example, of a cylindrical, stationary housing 1 made of steel or cast steel, which has at least three structurally identical reaction zones. With this housing 1 tightly connected, close in this embodiment, on both end faces of cylindrical cooling zones 1a, which can be externally cooled with liquid or gaseous cooling means or by heat radiation.
  • a thick-walled intermediate wall 1b is provided between the housing 1 and the cooling zones 1a , which has a passage opening through which the material can enter the first reaction zone or leave the last reaction zone.
  • the intermediate wall 1b serves as radiation and splinter protection.
  • the cooling zones 1a close input and output side of lock chambers 2. These seal the reactor with a slide 3 and gas-tight to the outside with a flap (not shown).
  • the material to be treated 14 is here in expediently rectangular cassettes 6 which are open at the top and form a form-fitting but not connected row through the entire reactor.
  • One or more unfilled cassettes 6 can be arranged between two filled cassettes 6 .
  • the housing walls of the entire reactor (sluice 2 , cooling zone 1a , reaction zones, cooling zone 1a , sluice 2 ) are preferably designed in the lower interior so that the correspondingly designed cassettes 6 can be moved (pushed) one behind the other without gaps and in a form-fitting manner through the reactor .
  • the pushing movement takes place by means of suitable devices 12 from the entrance lock in cycle times, corresponding to the required dwell times of the material in the reactor. Further installations along the inner housing wall (e.g. the inclined side walls 15 shown in FIG. 2 projecting beyond the edges of the cassette) prevent parts of the goods from falling under the cassettes 6 . There is a rupture disk 10 on the reactor which, when a permissible maximum pressure (eg an overpressure of 0.3 bar) is exceeded, releases the overpressure by bursting and thus protects the reactor from damage.
  • An ejection device is drawn with the reference number 11 .
  • Each reaction zone (five reaction zones are shown in FIG. 1) has a pilot burner 5 which can be set up from the outside by means of a suitable device so that the flame clearly touches the material to be treated.
  • the pilot burner 5 is preferably operated with fuel gas and air or oxygen.
  • the burner 5 is not in a reaction zone needed, it can be withdrawn or removed entirely using the device mentioned.
  • the pilot burners 5 can be adjusted, for example by varying the pressures of the gases supplied, in their flame pattern (geometry) and / or in their ignition energy to the respective explosives.
  • each reaction zone has at least one gas supply connection 9 and at least one gas discharge connection 8 - however, only connections 8 and 9 of three reaction zones are shown.
  • the connectors 8 and 9 are preferably arranged on the housing wall in such a way that a targeted atmosphere control, preferably transverse to the main axis of the reactor, is achieved.
  • Oxygen or combustion air additionally required for combustion in some cases can be fed to each reaction zone through lances 4 , which are arranged in such a way that the oxidizing agent strikes where the combustion takes place. Oxygen or air to support the combustion can also be added or, alternatively, added to the circulating reaction gas partial stream and then fed to the reactor via the gas feed pipe 9 .
  • Pipes (not shown) are connected to the sockets 8 and 9 and each lead to a manifold via motor-controlled control flaps.
  • each reaction zone is equipped with a flexible, gas-permeable splinterguard (here, for example, the armored chain curtain 7 ) in such a way that exposed, burning parts do not get into explosive-containing, but not burning, cassettes 6 .
  • Fig. 2 shows a cross section through a reaction space. It can be seen the circular structure of the housing 1 , the arrangement of the gas supply connector 9 and the gas discharge connector 8 so that a cross flow occurs.
  • the cassette 6 with the material 14 to be burned is located in the lower part of the reactor.
  • the burner 5 and the lance 4 for supplying oxygen are shown here on the right edge. The burner can be moved up and down. Its flame must be able to touch the combustion material 14 .
  • the housing 1 is designed in its central region (side wall 15 ) so that any solids escaping from the cassette 6 fall back into the cassettes 6 through the projections and the sloping side wall parts.
  • the cassettes 6 can be formed symmetrically to the longitudinal axis of the furnace or can be provided with a device from which the added oxidation medium (from FIG. 4 ) is conducted into or below the combustion material 14 .
  • a wall 16 a grate or a corresponding element that guides the inflowing gas into the combustion material 14 can be provided.
