Definitions

  • the invention relates to a method for the combustion of gases which are loaded with dusts, in particular pyrolysis gases from waste disposal plants, in a combustion chamber, the particles being kept in suspension, and a combustion chamber for use in this method.
  • the BRAM fuel from waste
  • the exhaust gases of such plants are particularly contaminated with organic compounds and especially with heavy metals, which preferentially accumulate on the fine dust.
  • These fine dusts are very harmful to health even without accumulation due to their ability to enter the lungs.
  • the use of such gases was only possible with great additional effort for cleaning the polluting substances.
  • elaborate cleaning systems for the exhaust gas had to be provided and due to the dust pollution, there were always disturbances in the Combustion chamber or in the downstream cleaning systems.
  • DE-OS 35 06 102 describes a coal-fired energy system in which coal dust is conducted through air at high pressure in combustion furnaces and is released in a cyclone downstream of the furnaces like unmelted ash.
  • this removal of the ashes is incomplete, so that a further precision dust removal device has to be connected downstream.
  • This additional process step requires additional equipment and energy, which reduces the economy of the overall process.
  • the object of the present invention was therefore to provide a method which allows the combustion of gases which are loaded with dusts.
  • the method is intended to allow the combustion of gas which is difficult to combust due to the dust load, without requiring excessive effort for cleaning systems for the exhaust gas.
  • the method should be used in connection with waste disposal plants.
  • Another task was to design the process so that dusts, ashes or sludges of any origin, also contaminated, can be converted into a form that allows safe disposal.
  • the method for solving the first-mentioned object is characterized in that the temperature in the combustion chamber is kept above the pour point of the dust, the dust particles melting in the combustion chamber and being discharged from the combustion chamber in liquid or reconsolidated form in a manner known per se.
  • the gas is thus advantageously burned in one step to generate energy and at the same time cleaned of the dusts contained therein.
  • the dusts are finally in a form in which they can be converted into glass-like granulate particles or shaped bodies in a simple manner, so that when the landfill is deposited, the toxins contained are washed out is no longer possible.
  • the resulting granules or molded articles are easier to handle than conventionally filtered dust due to the greater density and particle dimensions.
  • the process according to the invention provides that finely divided dusts, ashes or sludges are introduced into the gas intended for combustion before being burned for conditioning and kept in suspension and the temperature in the combustion chamber is above the highest pour point of the dusts , Ashes or sludge is kept.
  • the particles of dusts, ashes or sludge, which are initially in suspension, are also combined here by melting to form larger and thus heavier agglomerates. These cannot be carried further by the gas flow and therefore fall to the lowest point of the device under the influence of gravity. From there, they can then easily be drawn off in liquid form as a melt and fed to further processing, preferably also granulation or the formation of moldings, such as pellets, etc.
  • Particles that are still left in the exhaust gas can be removed from the exhaust gas by conventional dust separators, for example fabric filters, which are particularly suitable for fine dust, or electrostatic precipitators, and fed back into the melting process, whereby particularly good efficiency can be achieved.
  • the granulate particles or moldings ultimately produced are much simpler and safer to handle than the original dusts, ashes or sludges and do not require such strict safety precautions even when they are landfilled.
  • many pollutants are burned by the high temperatures required for melting, preferably between 1000-1500 ° C and thus rendered harmless.
  • the pollutants are integrated into the granules or shaped bodies by the melting together, so that they counteract Wash out or the like are safe and therefore safe from the environment.
  • the combustion chamber which comprises at least one supply line for the gas containing the dusts, ashes or sludges, if necessary at least one supply line for the heating medium, as well as at least one outlet for the treated gas and a discharge device for the molten particles, is characterized according to the invention in that at least one of the supply lines is pivoted with respect to the radial direction with respect to the axis of the combustion chamber, preferably between 10 and 60 °, but is at most exactly perpendicular to the radial direction.
  • Dusts, ashes or sludges must first be introduced into the flow of a gas at the beginning of one variant of the process. In principle, it does not matter at which point of the gas supply this introduction takes place. In the case of very large, heavy particles it is of course advantageous to mix them in relatively close to the point at which the melting process takes place, since otherwise too much of the particles could settle in the pipe system and hinder the further flow. In order to keep the dust particles in suspension for transport to the melting point and then in a, a favorable heating or. In order to maintain the distribution in the gas stream that ensures the combustion process, the dusts, ashes or sludges must be supplied in finely divided form.
  • the gas flow is then passed on and finally enters via one or more feed lines into the area in which the combustion of the gas and thus the melting of the suspended particles takes place.
  • the introduction of the dusts, ashes or sludges into a gas containing pollutants is another advantageous alternative.
  • the gas is also conditioned by the thermal afterburning and freed of the pollutants it contains.
  • the method is preferably carried out in a combustion chamber 1 (FIG. 1) specially designed for this. As has already been stated above, this has at least one feed line 2 for the dust-containing gas stream.
  • a gas supply line that is exactly perpendicular to the radial direction, that is to say tangential for round combustion chambers (FIG. 2a), is used in the case of combustion chambers with only one or two inlet openings, since the flow runs more uniformly along the combustion chamber wall.
  • the axes of the feed lines can form an acute angle with the tangential direction (FIG. 2b), which is preferably between 10 ° and 60 °.
  • FOG. 2b tangential direction
  • This feature results in a cylindrical, moving gas flow in which the dust particles are kept in suspension in the combustion chamber until they increase in weight and size due to the melting together and fall into the lower part 1 ⁇ of the combustion chamber 1.
  • This is essentially tapered downwards, so that the melt formed from the accumulated melted agglomerates collects at the lowest point of the combustion chamber 1 and is drawn off from there by a discharge device 3 in the liquid state.
  • the melt is then either granulated using conventional devices, not shown, for example a water bath into which the melt is introduced.
  • the fused particles can also be cast to form essentially any shaped bodies.
  • the fused particles are drawn off in re-solidified form.
  • Passive cooling can consist, for example, of allowing the fused particles to fall into ever cooler zones of the combustion chamber or the devices connected to them during the fall, whereby heat is radiated and the temperature of the particles finally drops below the pour point of the dust.
  • the temperature of the gas containing the molten particles or of the particles themselves can be actively reduced by measures known per se.
  • Heat exchangers can be provided to cool the gas (cooling by heat extraction), cooling media such as water or the like.
  • the treated gas whether inert carrier gas or exhaust gas from industrial plants, exits through at least one exhaust 4 in the direction of the axis of the combustion chamber.
  • the exhaust gas can be passed to a desulfurization, denitrification or similar system, and / or a conventional dedusting system can also be connected to remove residual dust remaining in the exhaust gas.
  • the in such a system e.g. Tissue or electrostatic precipitators, separated dust is advantageously returned to the combustion chamber 1 for melting.
  • the temperature of the exhaust gas of the combustion chamber 1 and thus of the fused particles after the heating by means of heat removal for example by means of a heat exchanger, by injecting water or the like, or addition of cold gaseous media, for example cold air, so far lowered that the particles solidify and the gas can be fed, for example, to heat recovery.
  • the cleaned gas can, for example, be sent for further utilization or can be discharged.
  • the separated solidified particles are advantageously added to the gas again before the heating in order to melt them again and to be able to remove them regularly.
  • an introduction device 5 is provided in at least one supply line 2 for the gas to be burned (FIG. 3a).
  • at least one introduction device 5 'opening directly into the combustion chamber 1' can also be provided.
  • the insertion devices 5.5 ', 5 ⁇ include, for example, injectors, cellular wheel distributors, nozzles and the like. the like
  • FIG. 3b a construction is advantageous in which the direction of introduction, usually represented by the extension of the axis of the introduction line into the combustion chamber, and the imaginary extension of the closest one The supply line for the gas intersect (intersection S in Fig. 3b, see also Fig. 2b).
  • the entire introduced material is caught by the gas flow, carried into the cylindrical flow and distributed well in it, thereby avoiding a rapid sinking to the bottom of the combustion chamber.
  • the gas could also be reintroduced into the process and used to transport the dust again if its properties have not adversely affected by the treatment.
  • the energy required for heating can at best only be achieved by burning this gas itself.
  • relatively high temperatures must be achieved for melting, preferably between 1000 ° and 1500 ° C. Therefore, the combustion chamber can also be heated by other types of heating, preferably direct firing.
  • the feasible variants range from the combustion of solid, liquid or gaseous fuels, such as coal dust, heating oil or fuel gases, to electric arc heating or the like.
  • Fig. 4a schematically shows an embodiment of a combustion chamber 1 according to the invention with supply lines 2 for a dust-containing gas and supply lines 6 for a heating medium
  • Fig. 4b shows a variant with supply lines 2 'for poor gas, ie fuel gas with a low calorific value, or 2 ⁇ for Rich gas and a feed line 6 for an oxygen-containing gas, preferably air, to improve the combustion of the fuels.
  • the high process temperatures of preferably 1000 to 1500 ° C place high demands on the heat resistance of the structural parts of the combustion chamber and their connected lines, parts, etc. Therefore, instead of the simplest uncooled version, which is only provided with a fireproof lining (Fig.5a) Cooling devices to be equipped.
  • a system 7 through which coolant flows and which comprises the chamber 1 is mainly provided, e.g. shown in Fig. 5b. This can go so far that the wall of the combustion chamber 1 is constructed from adjacent cooling tubes. This makes it easy to utilize the waste heat generated in the method according to the invention via heat exchangers for the said coolant.
  • the temperature of the inner wall of the combustion chamber must not be below the flow temperature of the dust, ash or sludge particles so that they do not solidify when they come into contact with the wall and adhere to the wall.
  • thermal energy inherent in the exhaust gas or carrier gas after the treatment can also be used in a corresponding manner, so that the combustion chamber according to the invention is suitable for incorporation into a heat recovery system.
  • the step of utilizing the thermal energy of the exhaust gas of the combustion chamber 1 leads to an advantageous lowering of its temperature.
  • residual dust components in the exhaust gas are thus solidified and can still be separated from the gas stream.
  • the exhaust 4 of the combustion chamber 1 can be provided with jet surfaces and / or other cooling internals 8, for example heat exchanger tubes (FIG. 6a).
  • Fig. 6b is also marked with 8 'a swirl breaker.
  • These are guide plates which are distributed along the circumference of the trigger 4 and point towards the center. They ensure the formation of a rectilinear flow, which is more favorable for the passage through downstream systems than the spiral exhaust gas flow created in the combustion chamber.
