Definitions
- the invention relates to a process for the controllable and environmentally friendly combustion of easily combustible substances or bodies made from easily combustible substances, e.g. Solid propellants, and a combustion device for performing this method.
- the substances or bodies are burned in a combustion chamber, optionally with the addition of an oxidizing agent, by a volume-detecting reaction.
- the combustion reaction which is difficult to control and often only incomplete, entails, among other things, the risk that the generally very reactive residual gases explode explosively. This has already led to serious accidents with these methods in the past.
- DE-OS 26 28 966 discloses a method for introducing waste gas-tightly enclosed in containers into thermal waste treatment facilities.
- the waste is collected in vacuum chambers and sealed gas-tight in the containers under compression.
- the containers are introduced on site or after an intermediate storage into a thermal waste treatment device working with overpressure and possibly in a vacuum chamber.
- the inorganic constituents of the waste are drawn off in molten form and cast into slag blocks, discharged from the thermal waste treatment device.
- a combustion furnace for highly toxic waste is known, which is constructed in the manner of a rocket combustion chamber and enables residue-free disposal of the waste with complete closure from the vicinity.
- a hot gas is generated in the combustion chamber, the composition and temperature of which is matched to the substance to be removed. Due to the heat transfer between the hot gas and the waste introduced into the combustion chamber, the toxins are freed from their carrier material, evaporated and decomposed, so that water vapor and carbon dioxide remain as the main products.
- the solid combustion products for example dust or ash, settle on the bottom of the container, for example, and can be disposed of regularly or at certain intervals. Due to the adaptation of the inner wall of the lock chamber to the shape of the body, the result is that the body lies closely against the inner wall of the lock chamber, at least in the region of the side surface (s), or forms a seal together with the latter. This is the prerequisite for controllable and gradual burning of the body. Due to the essentially gaseous reaction products, the interior of the container is to be designed much larger than the interior of the lock chamber. The arrangement of locking devices between the respective lock chamber and the container also enables continuous operation of the combustion device.
- the combustion products formed in the combustion zone additionally flow through at least one post-combustion zone.
- the position of the end face of the body in the lock chamber is fixed during combustion by means of a retaining element or a retaining device.
- the environmental conditions for the combustion reaction for example the ambient temperature, are the same at all times during the combustion.
- the body is continuously tracked by means of known mechanical, electrical or other methods, for example hydraulics is so that its end face lies against the retaining element and that the tracking speed is adapted to the burning rate of the body.
- the tracking can take place in accordance with the shortening of the body caused by the burning.
- an oxidizing agent e.g. Air or oxygen.
- the supply of air or oxygen is generally only suitable for substances with a negative oxygen balance in the combustion reaction.
- the oxidizing agent is supplied via at least one channel located in the body, for example a centrally arranged channel.
- the oxidizing agent can be fed from the front side of the body facing away from the container through the body to the combustion or post-combustion zone, which has the advantage that a backflow of combustion gases, for example past the outer sealing surfaces, can be effectively avoided .
- the substance to be burned is mixed with a material with a positive oxygen balance or that the body is filled with a material with a positive oxygen balance.
- the lock it came by rinsing, for example with air, cleaned, the connection between the lock chamber and the container was interrupted and another body was introduced into the lock chamber. Flushing the lock chamber before it is opened ensures that there are no reactive residual gases, such as hydrogen, in the chamber, "which would then potentially react explosively when the lock chamber is ventilated.
- any number of bodies can be used with the method burn one after the other in continuous operation.
- the gaseous combustion products are removed predominantly continuously, whereas the solid combustion products are periodically removed from the container.
- the gaseous combustion products accumulating in the container can be sucked off, for example, by means of a pump.
- the solid combustion components settle, for example, on the bottom of the container.
- the process according to the invention provides that the gaseous combustion products for disposal of the residual heat inherent in the combustion products are passed through a heat exchanger and that the gaseous combustion products for disposal of the residual gases are passed through a filter device .
- the efficiency of the method according to the invention can also be increased in that several lock chambers are operated simultaneously.
- several lock chambers can work together with one container.
- several containers can also be provided.
- the combustion device according to the invention can furthermore provide at least one additional chamber provided in the lock chamber for the afterburning.
- the combustion zone can be designed in the form of an additional chamber and serves the purpose of burning residual gases that have not yet burned in the combustion zone.
- the combustion device according to the invention can also provide means for supplying the oxidizing agent, for example metering valves or nozzles, which are provided on or in the lock chamber.
- the oxidizing agent can be introduced into the combustion or post-combustion zone in a spatially controlled and quantity-controlled manner.
- a spatial fixation of the end face of the body in the lock chamber can ent by a projection in or on the inner wall of the lock chamber through which the body is retained at the level of the end face or by a Gi arranged in the lock chamber on which the end face of the body is present.
- the combustion device according to the invention can further provide spacer elements for lining the inner wall of the sluice chamber, for example pipe sections. This makes it possible to adapt the inner wall of the lock chamber to different bodies.
- the end face can be fixed in spite of the body length changing during the combustion by a hydraulic system provided in or on the lock chamber with a pressure piston for the pressure and the tracking of the body.
- the combustion device according to the invention can furthermore have at least one solids disposal connection provided on the container, via which the solid combustion products which, for example, settle on the container bottom, can be removed.
- the final disposal of the residual heat of the combustion products as well as the residual portion of dust and toxic gas can be carried out by at least one heat exchanger arranged inside the container or behind the outlet of the container and at least one filter device arranged behind the outlet of the container.
- the combustion device according to the invention can have at least one trickle tower for converting nitrogen dioxide into nitric acid, at least one active carbon filter element for filtering off the other nitrogen oxides and at least one collecting device for the nitric acid.
- the nitric acid can be incorporated into a raw material cycle by recycling during fertilizer production.
- the combustion device according to the invention can furthermore have at least one intermediate container arranged in front of the filter device. Due to the buffer effect, the intermediate container permits the continuous and efficient use of a filter system.
- the combustion device according to the invention can provide at least one compressor or fan arranged in front of the filter device. These devices enable the gaseous combustion products to be extracted into a filter system.
- the combustion device shown in FIG. 1 has a lock chamber 1, which is cylindrical in this example and into which a cylindrical body 2, for example a fuel set, is introduced.
- the inner wall of the lock chamber 1 is adapted to the outer shape of the body in the area of the body 2.
- Equipping the lock chamber 1 with the body 2 takes place through a closure 3 of the lock chamber 1.
- the body 2 is pressed with its end face 5 against a grid 6 by means of a pressure piston 4 connected to a hydraulic system (not shown). By this means it is achieved that the body 2 fits tightly during the combustion, the end face 5 to the grid 6 and 'thereby the position of the end face 5 is fixed in the Schleusenkam ⁇ mer. 1, the body 2 is now to initiate the combustion reaction to of the end face 5.
- an oxidizing agent for example oxygen
- the lock chamber 1 is in a closable connection with a pressure-tight or gas-tight container 12 by means of a gas-tight or pressure-tight slide 13. After the slide 13 has been opened, the body is introduced into the combustion zone 7 (the state already opened is shown here) and ignited at the end face, for example by an electron or electric heater. Thereafter, the reaction products formed in the combustion zone 7 or the post-combustion zone 8 are sucked into the container 12 due to the pressure drop present.
- the solid portions of the products settle on the bottom of the container 12 and can be removed via a solids disposal nozzle 14.
- the gaseous combustion products are suctioned off for further disposal.
- These first flow through a heat exchanger 16 in which the heat of the residual gas can be used or disposed of and are then pumped into a buffer store 18 by means of a pump 17.
- the residual gas is supplied via a com- pressor v 19 a filter device 20 in which a final chemical purification of the residual gas er ⁇ follows.
- the filter device 20 consists of a trickling tower 21 in which the nitrogen dioxide obtained is converted into nitric acid, an activated carbon filter 22 for absorption of the other nitrogen oxides and a collecting device 23 for concentrating the nitric acid.
- the resulting nitric acid can finally be used in fertilizer production.
