Definitions

  • the invention relates to a method for burning explosives and explosive objects.
  • Explosives are solid, plastic or liquid explosive substances such as explosives, fuels and gunshots, 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.
  • explosive is understood to mean both the explosive in the sense of the above definition and explosive objects which have been dismantled, delaborated and portioned to the extent that they can be fed into a combustion process with due care.
  • a process is known from the USA (establishment of the US Army in Utah, we do not have a written reference) in which explosives in an open rotary kiln, which is charged in portions, are used with extremely high excess air, partly due to the action of the hot air flow, partly are ignited and burned by direct contact with a flame that burns axially into the rotary kiln.
  • total fresh air supply, fuel supply for the flame, rotational speed of the drum furnace and loading quantity and frequency are varied. Emissions of combustion gases from the unsealed end faces of the rotary kiln are prevented as far as possible by intake of false air.
  • the disadvantage is that here largely non-specific explosives are burned using relatively large amounts of fuel, so to speak.
  • EP 349 865 A2 describes a combustion process "while maintaining the character of an open fire place" (column 3, line 2).
  • column 3, line 2 the extraction system must be dimensioned so that it can cope with these increased amounts of exhaust gas: this leads to the above-mentioned quantities of false air even in normal operation.
  • the object of the invention is to treat explosives of a wide variety of chemical compositions that have become unsuitable for use, that should or should no longer be used according to their intended use or that arise as residues from production, in a thermal process so that they lose their explosion hazard and the reaction products and residues arising from the treatment can be reused (e.g. metal scrap), further environmentally friendly treatment (reaction gases, unburned, combustible residues) or safely landfilled (minerals, slags).
  • the explosive is preferably transported in suitable open containers in cycles through an inertizable lock chamber by means of a transport device into and through a fixed furnace space. At the end of the container, the containers leave the furnace via an inert lock chamber. After entering the furnace, the explosive is ignited by direct contact with one or more open flames. Combustion oxygen or air is also supplied at this point if necessary, depending on the process control mixed with recirculated and cooled reaction gases from the subsequent combustion. In the next cycle, the ignited explosive is transported from the ignition zone into a combustion zone, from which the resulting exhaust gases, which are composed of flue gas, reaction gases and any excess air or oxygen still present, are removed. Part of this exhaust gas stream can be cooled and returned to the ignition zone, the rest leaves the reactor and is treated in downstream exhaust gas cleaning systems.
  • the kindling and burning zone can extend over several cycle times. If necessary, the lighting and burning cycles can be repeated several times in succession. This is possible because pilot burners, suction and supply devices installed over the length of the combustion reactor are activated or shut down as required.
  • at least three stations should be provided in the furnace. The first stations are ignition zones; the other stations are burning zones and optionally also ignition zones. Another burner is provided in the last station, which reliably burns off the remains. This intermittent build-up allows the detonation to be started again after the burn-off zones if the explosive does not continue to burn itself.
  • the partial recirculation of the exhaust gas stream over one or more cycles ensures that there is a sufficient gas flow in the reactor with the least possible excess of oxygen / air. By cooling this partial flow, the process can be operated below an explosive-specific maximum temperature.
  • reaction-related pressure fluctuations can be buffered so that their effects on the downstream exhaust gas cleaning systems are limited.
  • the invention is illustrated by a figure.
  • the combustion furnace 1 expediently in a cylindrical design, has a gas-tight, inertizable lock chamber 2, 2a on the inlet and outlet sides. These are connected to the actual combustion part of the furnace 1 via a cooling zone 3, 3a.
  • These cooling zones 3, 3a which can be actively cooled by water or air or passively by radiation and free convection, on the one hand protect the sealing elements of the locks from the effects of heat and, on the other hand, prevent auto-ignition of the explosive entering.
  • the combustion chamber of the furnace 1 consists of at least three reaction zones of the same type (five reaction zones are shown in the figure), in which the gas flow direction is essentially here Chen is forced transversely to the main axis of the furnace 1. This is done in that the main part of the gas flow is blown in parallel into the individual reaction zones across the furnace axis by means of the fan 4 via the gas supply lines 5 and leaves the reaction zones again through appropriately arranged gas discharge lines 6.
  • the derived gas streams are combined in a collecting tube 7 and fed to the fan 4 via the dust separator 8, expediently a multicyclone, and the gas cooler / condenser 9 in order to be blown into the reaction zones again.
  • the gas cooler / condenser 9 has the function on the one hand of cooling the circulated gas stream to such an extent that the desired temperature can be maintained in the reaction zones of the incinerator and on the other hand the task of removing metal vapors, e.g. Mercury and cadmium to condense out.
  • metal vapors e.g. Mercury and cadmium to condense out.
  • the incinerator 1 is equipped with a suitable device 11 which allows containers 12 which are open at the top to be cyclically transported through the furnace 1 via the locks 2, 2a.
  • each reaction zone of this incinerator there is a pilot burner 10, which e.g. is operated with gas (supply line 13) and possibly air or oxygen (supply line 14).
  • the flame of the pilot burner is set so that it clearly touches the explosive located in the containers 12. If a reaction zone is only passed through as a burning zone, the pilot burner 10 is switched off and, if appropriate, is withdrawn into a corresponding rest position.
  • air or oxygen for combustion of the explosive can be supplied by lances or, in another embodiment, can be added to the cycle gas before entering the reaction zone.
  • the reaction zone closest to the end of the furnace should always have a pilot burner for safety reasons.
  • the temperature control in the individual reaction zones of the furnace is carried out individually by varying the gas return admixture by means of the control flaps 15.
