Definitions
- the present invention relates to a plant for burning off explosives, with a burn-off reactor and with a conveyor device running inside and outside the reactor with a plurality of burn-off carriers which load the explosives outside the reactor and then into the reactor an ignition device for the explosives and from there with the burning explosives are transported further within the reactor and finally leave the reactor again after the burning has ended.
- Such systems are known and are used for the disposal of objects with explosive or explosive substances, e.g. Ammunition, missiles, pyrotechnic sets, etc., especially from the military sector.
- the reasons for disposal lie either in the fact that the objects mentioned have reached a certain age, from which the defined properties guaranteed in the manufacture of the explosive or explosive substances and required for their use can no longer be guaranteed, or because For example, have developed weapon systems and the ammunition already produced and stored for these weapon systems can no longer be used for their intended use.
- the explosive or explosive substances mentioned are referred to with the term “explosives”. These are generally understood to mean solid, liquid and gelatinous substances and mixtures of substances which are produced for the purpose of blowing up or blowing up. However, in the present case, the term “explosives” also includes those substances that were not produced for the purpose of detonating or shooting, for example organic peroxides as catalysts, gas release agents for today's foam and plastic technology, some pesticides and much more L
- Thermit which is understood to mean mixtures of aluminum and iron oxide, which convert to aluminum oxide and iron with strong heat development. This heat development is used, for example, for rail welding.
- Explosives can be present both in the form of bulk goods of any grain size, buildup, in the form of bodies with defined dimensions (e.g. compacts) or as a filling compound in hollow bodies.
- bodies with defined dimensions e.g. compacts
- Explosives can serve as a guide to the groups of substances to be understood under the term "explosives”.
- the known systems for burning off explosives mentioned at the outset provide - predominantly - in a traditionally known manner for burning completely outdoors, or - like for example the system described in DE-OS 38 22 648 - in a safety device -Building, which has the character of an open fire place due to its construction with a partially open discharge wall.
- Personal security is at the known systems of the first type are guaranteed by simple earth protection walls which surround the burning point or at least shield in the direction of personnel present, or in the case of a system according to DE-OS 38 22 648 by a solid wall of a security building which for example, separates the burn-off area from the loading area.
- the object of the present invention is to design a plant for burning off explosives of the type mentioned at the outset in such a way that essentially complete emission protection is ensured while at the same time maintaining full personal safety.
- This task is the responsibility of the fourth Federal Immission Control Ordinance (4th BImSchV), the explosive destruction guidelines of the employer's liability insurance association of the chemical industry and the accident prevention regulation "46a Explosives and objects with explosives - General regulation - (VBG 55a) "taken guidelines or regulations.
- This object is achieved according to the invention in a plant for burning off explosives of the type mentioned at the outset in that the burning reactor is arranged within an essentially splinter- and explosion-resistant tunnel.
- the advantages of this invention lie in particular in the fact that the combustion reactor and the splinter and explosion-proof tunnel form a closed combustion system in which the gaseous components of the reaction products formed during the combustion are collected and, after the pollutants have been reduced, are released into the environment ⁇ emitted ambient air and the liquid and / or solid reaction products are processed into environmentally compatible materials suitable for landfill, while at the same time a personal safety corresponding to the legal regulations is guaranteed when the combustion is carried out. It is particularly advantageous here that the requirements of the 17th BImSchV and the emission limit values of the TA-Luft can be complied with while ensuring personal safety in accordance with the legal and professional regulations.
- the tunnel is preferably formed from a pipe and a sand covering of the pipe, a further development which primarily concerns personal safety in the event of an (unwanted) detonation of the explosive when it burns.
- the burn-up reactor - starting from the detonation source - is broken down into fragments which penetrate the tunnel tube at a very high speed in front of the detonation shock wave and, depending on the intensity of the detonation, also break it down.
- the sand covering surrounding the tunnel pipe has two tasks: on the one hand, the sand covering serves to collect the splinters of the burning reactor and, if necessary, the splinters of the tunnel pipe.
- the sand cover will collapse and cover the center of the erosion if the tunnel tube also disassembles.
- the sand covering and encompassing the tunnel tube thus makes one extremely flexible on the one hand, since it is not rigidly insulating, and on the other hand, an extremely safe and effective protective jacket, which at the same time extinguishes a fire which arises during the detonation, is formed.
- a construction of the tunnel tube that is as simple to implement as possible is provided by a development according to which the tube is preferably composed of oval steel tube profiles.
- the advantages of this oval shape lie in particular in the fact that these profiles are generally commercially available and that accessible inspection passages are formed on the two long sides of the combustion reactor.
- the burn-up reactor has a substantially rectangular shape, elongated in the direction of transport of the conveyor, and according to the other preferred development it is provided that the fuselage of the burning reactor consists of metal profiles.
- the fuselage of the burn-off reactor can be made from profiles of other materials, e.g. Plastic.
- Another advantage of the construction of metal profiles is that the burn-up reactor can thus be prefabricated inexpensively outside the tunnel tube and built inside the tunnel tube.
- the inside walls of the fuselage reactor are preferably lined with temperature-resistant fiber material.
- the fiber material primarily serves to collect the very large temperature difference which occurs when explosives are burned off in the burn-off reactor.
- the temperature in the combustion reactor rises - starting from the combustion source - in its surroundings and in particular above the combustion range to 2,000 to 3,000 ° C. within seconds, since the chemical decomposition reaction of explosives is a highly exothermic process i acts.
- the temperature-resistant fiber material is arranged in order to intercept the heat radiation which arises and in particular to keep it away from the metal profiles of the burning reactor. Rock wool is preferably used here.
- the combustion reactor preferably has an air suction device with at least one feed nozzle arranged in the input region of the combustion reactor and at least one extraction nozzle arranged in the output region.
- the entrance area is separated from the burning area by a lockable shutter, the slats of which are in particular individually, i.e. can be set independently of one another.
- the venetian blind achieves several essential advantages in connection with the air flow passing through the combustion reactor: on the one hand, the venetian blind can be used to set an advantageous flow direction through the combustion reactor, which should be designed such that the fresh air supplied is on the one hand mixed as quickly as possible with the resulting hot exhaust gases, thereby cooling the exhaust gases and causing oxidation of the reaction products which have not yet been completely combusted, but on the other hand avoiding whirling up of the explosives present in the combustion carriers.
- the level of the main air flow through the combustion reactor can be varied from an upper region to a middle region to a lower region.
- a certain negative pressure can be set in the combustion reactor at a certain volume flow. This negative pressure ensures that the gaseous reaction products only leave the burn-off reactor via the air suction device. This results in the economically significant advantage that the combustion reactor may generally be leaky, which enables a more cost-effective production.
- the entrance area and the exit area each have a passage for those entering or leaving the combustion reactor by means of the conveying device 1
- a spark flap is arranged in the area of the transition from the entrance area to the burning area at the end of the entrance passage. This is preferably designed to be rebound-damped and prevents sparks from being transported from the explosives currently burning in the burning area to the explosives still located on the burning supports in the area of the entrance passage.
- a particularly preferred embodiment of the conveying device and the associated large number of erosion carriers is that the erosion carriers are designed as mobile carriages which have a trough for receiving the explosives to be burned off.
- the erosion carriers can be designed in the manner of "lorries", which then - according to a preferred development of the invention already explained above - essentially the entrance and exit passages during their passage, i.e. Seal airtight except for a defined residual air flow. This residual air flow passes through the undercarriage area of the combustion carrier into the combustion reactor and, on the one hand, cools the troughs containing the explosives and, on the other hand, cleans the roadway on which the combustion carriers roll through the combustion reactor.
- the sand covering covering the tunnel tube is preferably supported laterally by solid walls, one of these solid walls parallel to the tunnel separating a charging area for charging the burn-off carriers with explosives.
- the conveying device can thus include a rotating rail for the mobile wagons, which runs through the loading area, leads to the combustion reactor and subsequently reconnects the end of the exit passage with the loading area.
- a cleaning device for the gaseous reaction products formed during the burning is connected downstream of the burning reactor or the suction port of the air suction device.
- the cleaning device contains washing stages which separate the pollutants occurring in all aggregate states from the exhaust gas.
- the cleaning device can furthermore contain thermal pollutant reduction stages or, alternatively or cumulatively, biological pollutant reduction stages.
- FIG. 1 shows a cross section through the essentially splinter-proof and explosion-proof tunnel with the combustion reactor arranged therein;
- FIG. 2 shows a schematic plan view of the tunnel with sand cover
- FIG. 4 shows a cross section of the burn-up reactor with burn-up supports passing through in the transport direction
- FIG. 5 shows a schematic side elevation of the tunnel according to FIG. 2.
- FIG. 1 shows a burn-off reactor 1 of a plant for burning off explosives, which is arranged within a tunnel 2 which is essentially splinter-proof and explosion-proof.
- This tunnel 2 consists of an oval tubular steel profile Compound tube 4 and a tube cover 4 covering the sand 4, which in turn is supported laterally by solid walls 12, 13 and is covered by an upper cover 25.
- the burn-up reactor 1 stands inside the tunnel tube 4 on a concrete floor 23 and has a height of about 3 m, while the tunnel tube 4 has a clear height of about 4 above the concrete floor 23.
- a charging area 14 for charging burn-off carriers 16 with explosives to be burned off, which is separated from the tunnel 2 by a fixed wall 13.
- the tunnel tube 4, the sand covering 6 and the fixed wall 13 ensure the personal safety required when operating a system for burning off explosives.
- the processes taking place in this regard in the event of an (unwanted) detonation of the explosives which are actually to be burned off will be explained below.
- the loading area 14 is connected by means of a conveyor 11 (only partially shown in this figure) to the tunnel 2 or the burning reactor 1 arranged therein and forms an endless transport route, in particular oval, on which the conveyor 11 is conveyed belonging to the burn-off carrier 16 after the loading area 14 first through the input area 3 of the burn-off reactor 1, then through the burn-off area 7 and then through the output area 5 of the burn-off reactor 1 and are then fed back to the loading area 14 (FIG. 2 , 4).
- the reactor 1 has a substantially rectangular shape, elongated in the direction of transport of the conveyor 11 (FIG. 4), and the body of the reactor 1 is constructed from metal profiles 8.
- the inside walls of the fuselage of the combustion reactor 1 are lined with rock wool 10 to protect the metal profiles 8 against the very high temperatures (up to 3000 ° C.) that occur when explosives burn up.
- the burn-off reactor 1 also has an inlet 26, the inlet area 3 already mentioned above, the burn-off area 7 and also the outlet area 5 and an outlet 27 (FIG. 4).
- the burn-up reactor 1 rests on the concrete floor 23 inside the tunnel tube 4.
- 2 and FIG. 5 show a plan view and a side view of the tunnel 2 with the sand cover 6, the burn-off reactor 1 not being shown here.
- the illustration shows the essentially rectangular and elongated shape of the tunnel 2 as a whole.
- the input area 3, the burn-off area 7 and the output area 5 of the burn-off reactor 1, not shown, are indicated by the reference numerals in brackets.
- FIG. 3 shows a cross section of the burn-up reactor 1, enlarged compared to FIG. 1, at the level of an ignition device.
- a combustion carrier in the form of a mobile carriage 16 is shown within the combustion reactor 1 and has a chassis 15 which can be moved on wheels 28 and a trough 21 arranged thereon for receiving the explosives to be burned off.
- a partition 24 can also be seen behind the tub 21, which is arranged vertically behind the tub 21 on the chassis 15 of the cart when looking in the transport direction of the cart 16.
- a burner 22 of the igniter by means of which the explosives are ignited, are arranged to the right and left of the carriage 16.
- the combustion carriers or carriages 16 are guided by a guide device 29 belonging to the conveying device 11 and corresponding guide rails 33 or are also driven via these components.
- a suction nozzle 19 of an air suction device which is arranged in the exit region 5 of the burning reactor 1, can be seen, the function of which is explained in more detail with reference to FIG. 4.
- FIG. 4 shows a longitudinal section through the combustion reactor 1, which is traversed by a large number of combustion carriers or carriages 16 which have already been described above and which carry or transport the explosives to be burned off from the charging area 14 to the combustion reactor 1 Transport the residues generated during the burn-up for further disposal.
- the wagons 16 loaded with explosives move through the entrance passage 9 of the entrance area 3 into the burning reactor 1 and are fed to the burning area 7 one after the other.
- Burners 22 arranged where the ignition of the explosive takes place in the trough 21 of the car 16 concerned.
- a spark flap 17 is arranged in the area of the transition from the entrance area 3 to the burning area 7 at the end of the entrance passage 9, which dampens kickback to avoid further spark formation is.
- This spark flap 17, in cooperation with the partition 24 of the following carriage 16, closes the entrance passage 9 largely airtight.
- the carriages 16 are slowly transported with the burning explosives from the position of the burner 22 in the transport direction, so that the combustion of the explosives takes place completely within the combustion reactor 1.
- the duration of such a burn-up is on average in the range of seconds to minutes.
- the wagons 16 leave the burn-up reactor 1 through the exit passage 9 'belonging to the exit area, which - like the entrance passage 9 - is sealed off essentially airtight by the construction of the carriages 16 (in particular partition 24). Similar to the entrance passage 9, only a small but wanted portion of fresh air reaches the burning area 7 in the direction of the arrows 31 through the exit passage 9 '.
- the air suction device of the combustion reactor 1 already mentioned above contains in the input area 3 of the reactor 1 supply ports 18 arranged on both sides (of which the intake grille of the one supply port is shown here) and an exhaust arranged centrally in the output area 5 of the reactor 1 - ML suction nozzle 19.
- This suction nozzle 19 is followed - not shown here - by a cleaning device for the reaction products formed during the fire.
- this cleaning device contains washing stages for separating the pollutants occurring in all aggregate states from the exhaust gas, and — alternatively or cumulatively — thermal or biological pollutant reduction stages.
- the air sucked in through the feed pipe 18 and sucked out through the suction pipe 19 in the direction of the arrows 32 essentially has three functions. On the one hand, it ensures the quantitative transport of the gaseous reaction products and the aerosols contained therein into the scrubbing stage for flue gas scrubbing. On the other hand, however, the air is required in order to limit the inlet temperature in the washing stage, which preferably contains a Venturi scrubber, to a maximum value of approximately 300 ° C. This is particularly important, especially in view of the background already described at the beginning in connection with the lining of the burning reactor 1, that the explosives burn off at temperatures of up to 3000 ° C.
- the third function of the air sucked in or out within the reactor 1 is to be seen in the fact that it is intended to set oxidizing conditions within the burning reactor 1 so that the proportion of non-oxidized substances which arise during burning is as possible is kept low.
- This air thus serves to supplement the burnup by residual combustion of the inadequately or insufficiently oxidized substances and thus to increase the emission reduction.
- the air flow directed from the supply connection 18 to the suction connection 19 can be set to a defined value in the flow direction and air quantity by the adjustable blind 20, which can be locked with regard to its slat position.
- the washing stages of the cleaning device can also include one or more wet scrubbers. While the venturi scrubber has the task of bringing the approximately 300 ° c hot exhaust gases to a cooling limit temperature AZ to cool and separate most of the aerosols, such as soot, metal compounds, phosphorus pentoxide, etc. (depending on the exhaust gas composition, other pollutants such as HCL, HF and, due to the then low pH value, alkaline pollutants) , such as ammonia).
- a cooling limit temperature AZ to cool and separate most of the aerosols, such as soot, metal compounds, phosphorus pentoxide, etc. (depending on the exhaust gas composition, other pollutants such as HCL, HF and, due to the then low pH value, alkaline pollutants) , such as ammonia).
- One of the wet scrubbers can be provided for the acidic portions of the exhaust gases (in particular HCL, HF and NH3) and one for the basic portions of the exhaust gases. While the acid scrubber is designed as a spray scrubber in the countercurrent principle, the basic scrubber works in the cocurrent principle at a pH of approx. 9. Weaker acids such as SO2, H2S and HCN are absorbed in the basic scrubber.
- the burn-up reactor 1 is broken down into fragments which fly through the tunnel steel tube 4 at a very high speed and, if appropriate, also break it down.
- the splinters of the burn-up reactor 1 and the tunnel steel tube 4 are caught by the sand cover 6, the sand cover 6 covering the detonation hearth when the tunnel steel tube 4 is dismantled and extinguishing a fire to be expected with the sand.
- the above-described plant for burning off explosives makes a considerable contribution to the reduction in emissions which is appropriate for the environment, while at the same time maintaining full personal safety.
- the expected contaminants hydrogen chloride, phosphorus, sulfur oxides, hydrocyanic acid and nitrogen oxides are bound and disposed of in the system described.
- the design of the system basically enables the disposal of all accumulating pollutants for which cleaning systems or methods are or can be implemented economically and technically at present or in the future.
- the presented combustion plant enables all of them to be connected afterwards Cleaning devices, without changing the core of the combustion plant, namely the combustion reactor 1 arranged inside the essentially splinter-proof and explosion-proof tunnel 2.
