Definitions
- the invention relates to a method according to the preamble of claim 1.
- a method of this type is known from DE-A-33 07 848.
- process fumes such as combustion gases containing flammable constituents
- a venturi-like entry device according to the The principle of a circulating fluidized bed works Fluidized bed reactor fed and burned there and cleaned.
- the solid phase by a clear density jump from the one above Gas space is separated during this procedure - i.e. in the circulating fluidized bed - distribution states of the circulating solid without defined Aimed at the boundary layer at which the solids concentration inside the reactor from the bottom up decreases.
- a steady decrease in the solids concentration is desirable from bottom to top within the circulating fluidized bed. So far, this has only been possible with circulating fluidized beds not with venturi-like entry device can be achieved. It has been observed that solid particles down in the edge areas of the fluidized bed sink and settle in the bottom, narrowest area of the bottom Collect the conically tapered fluidized bed reactor. This Solid particles are then circulated at this point and hardly get into circulation anymore. Especially at Treatment of process gases with sticky components, e.g. molten solid such as fly ash solid agglomerations, at this point tennis ball size reachable.
- sticky components e.g. molten solid such as fly ash solid agglomerations
- the accumulation of solids in the lower one The area of the fluidized bed reactor creates a constriction at the entry point in the fluidized bed reactor, whereby the process gas flow is restricted and accelerated becomes. This means there is less time to treat the Process gases available as intended.
- the inhomogeneous Distribution of the solid causes an insufficient Heat exchange and temperature jumps in the reactor.
- Another disadvantage of the known circulating Venturi fluidized bed is that the solids circulation is smaller than with a conventional fluidized bed.
- the present invention is based on the object Process of the type mentioned above and a fluidized bed reactor to carry out the procedure with a steadily decreasing suspension density from bottom to top to create the residue particles. This leads to one improved heat exchange and an even temperature distribution.
- the continuous distribution can be even optimize up to approximately exponential distribution.
- Process gases are understood as industrial gases, in particular those from waste incineration.
- the treatment of such gases according to the invention includes, for example, cooling, dry cleaning (removal of HCl, SO 2, etc.) and / or post-combustion.
- the use of a circulating fluidized bed for cooling (quenching), dry cleaning or afterburning of process gases from a furnace and its advantages are known from the above-mentioned DE-A-33 07 848.
- the process gases are used as fluidizing gases; sand, an adsorbent and / or a reagent, for example, are used as the fluidized bed solid.
- the bed material is preferably formed at least in part from the fly ash originating from the furnace.
- the bed material is distinguished by an excellent heat transfer medium which, with a suitable distribution of solid particles, enables a uniform temperature distribution in the fluidized bed reactor, the temperature being easily controllable in a manner known per se, for example via an external fluid bed cooler.
- a fluidized bed reactor 1, 1 ' a fluidized bed reactor 1, 1 ', only the lower part of which is shown in the drawing is a diffuser area that widens conically upwards 2, in which a cylindrical channel 4 for Introducing the process gases to be treated opens.
- the Process gases forming a core jet K flow in the direction of the arrow through the cylindrical channel 4 into the fluidized bed reactor, 1, 1 '.
- the diffuser area 2 forms together with the cylindrical channel 4 and one on these at the bottom adjoining 5 a venturi-like Entry for the process gases.
- the outlet opening is 8 of the cylindrical channel 4 opposite the Bottom edge zone 6 into the interior of the fluidized bed reactor 1 transferred.
- FIG. 2 of a fluidized bed reactor 1 ' is the outlet opening 8 'in the same plane as the bottom edge zone 6.
- Nozzles 9 are used. About the nozzles 9 are in the fluidized bed reactor 1 concentrically and preferably parallel to that emerging from the outlet opening 8 Core jet K a plurality of auxiliary gas flows denoted by arrows H. injected into the fluidized bed reactor 1.
- the auxiliary gas flows about concentric in several circles around the Channel 4 arranged bottom openings 10 'injected, whereby a uniform soil fluidization in the annular Bottom edge zone 6 is reached.
- the auxiliary gas flows both through the nozzles 9th as well as to inject through the bottom openings 10 'at the same time.
- the auxiliary gas flows can either be from an additional Gas or part or all of the process gas be formed.
- At one that takes place in the fluidized bed reactor Afterburning is advantageously an oxygen-containing one Gas, preferably with the auxiliary gas streams H, supplied.
- the invention is further illustrated by the following example illustrated.
- Air was injected into the afterburning chamber of a pilot plant for the afterburning of process gases as auxiliary gas flows over 12 lances with a diameter of 10 mm between 50 and 250 m 3 / h iN (corresponding to an exit speed of 15-75 m / s iN).
- 15 to 50 m 3 / h iN (corresponding to a fluidization rate of 0.08-0.27 m / s iN) were injected with a further auxiliary gas stream for the soil fluidization.
- the amount of flue gas entering the afterburning chamber was 800 to 1400 m 3 / h iN at a temperature of 1200 ° C to 1600 ° C.
- Typical was a flue gas quantity of 1200 m 3 / h iN and 1500 ° C with an auxiliary gas quantity introduced by lances of 150 m 3 / h iN and optionally a further quantity of auxiliary gas for the soil fluidization of 15 m 3 / h iN
- the ratio of the outer diameter of the bottom edge zone 6 to the diameter of the channel 4 or the outlet opening 8 for the core jet is preferably 3: 1 to 10: 8.
- the auxiliary gas streams H swirl the solid particles again loosen up, loosen, hover and promote them into the core jet K without causing deposits and caking comes.
- Any coarse ash can be easily be deducted (the coarse ash deduction is shown in Fig. 1 and 2 with 11, the withdrawal direction with an arrow A).
- the coarse ash deduction enables optimization the pressure drop in the fluidized bed reactor. This will also requires a lower suction power, which is a allows simpler construction of the system.
- a quieter operation due to the method according to the invention achieved by pulsations in the process gas supply is less dependent.
- both the intern as well as the external solids particle circulation increased.
- the good mixing of solid particles with Auxiliary gas flows into the core jet cause a lot good quench effect (e.g. from 1600 ° C to 900 ° C). This is for example, of particular importance for flue gas cooling.
- the aforementioned increase in solid particle circulation also has an increase in the fluid bed cooler extractable for further use Heat energy result.
- the main advantage of the method according to the invention or the fluidized bed reactor according to the invention in bringing about a constant suspension density distribution in the circulating fluidized bed with a venturi-like Infeed and thus optimal process control within the circulating fluidized bed.
