Definitions

the invention relates to a method for processing slag of a combustion apparatus, in which the slag is separated from the combustion apparatus by means of a slagger.
the gas stream after the air classification can first be fed to a cyclone separation and then to a filtering process as required. This makes possible separating the slag into a coarse fraction of several millimeters in diameter and a fine fraction having a smaller diameter, whereby dust is avoided as much as possible and unavoidable dust can be separated by means of a cyclone and a filter.
the combustion residues could contain health-relevant, respirable, fractions thereof. This is uncritical for the discharged with the combustion exhaust gas due to the thermal convection or the velocity of these gases from the combustion chamber in a downstream steam generator and the subsequent exhaust gas purification particles, as a nearly quantitative separation takes place in the filters of the emission control system. More problematic is the flow of material from these materials, leaving the combustion chamber with the burnt fuel remains, z. B. with the ash and slag, and then to be used for further use. These are not only the majority of these substances but also a contamination of the entire solid waste fraction after incineration.
the invention is therefore based on the object of developing a generic method such that the slag of incinerators has as little as possible particle dust and fibers from these fractions even with a combustion of CFRP, GFRP and / or nano-materials.
the invention is based on the finding that it is advantageous to produce a very fine fraction which essentially has particles with a diameter of less than 500 ⁇ m.
This ultrafine fraction can be separated from the residual slag, for example, with an air classifier.
the diameter of the particles corresponds to the diameter that would have a particle with the same volume in spherical shape or it corresponds to the aerodynamic diameter.
the aerodynamic diameter is thus above the diameter of the fiber. For example, if one speaks of a fraction with a diameter less than 2,000 microns, then this fraction may also have thin fibers, for example, 10 mm in length and a few microns in diameter.
the separator or a subsequent separating or separating device ensures that the ultrafine fraction has the predominant proportion of a fraction of fiber materials, fragments thereof and nanoparticles. It is envisaged to quantitatively remove fiber materials, fragments thereof as well as nanoparticles with this ultrafine fraction, ie to remove more than 80% and preferably more than 95% and particularly preferably more than 98% of the fiber materials, the fragments thereof and the nanoparticles from the slag ,
the separator can be based on different physical separation principles and, in particular, it is also possible to use several separation principles one after the other or even superimposed simultaneously.
the separator has a fabric filter.
a fabric filter makes it possible to separate very fine materials from a gas stream.
a mass separator also referred to as a mass decompressor, is an apparatus for separating particulates due to inertial forces.
the operating principle of mass force separators relies on the fact that the particles suspended in the gas can no longer follow the flow movement and are deposited on internals or walls.
Mass energy separators are distinguished by the effective transport forces of gravity, inertial force and centrifugal force. The mass forces responsible for the particle separation act transversely or against the flow resistance force and are directly proportional to the particle mass, so that the respective forces are proportional to the third power of the particle diameter.
inertial force separators are preferably used to deposit particles having an aerodynamic diameter of at least 2 ⁇ m, it is proposed to use a mass force separator to separate from the dust particles with an aerodynamic diameter of more than 1 ⁇ m or more than 2 ⁇ m. For particles of this size, the influence of diffusion can be neglected.
the aerodynamic diameter is defined as the diameter of a spherical particle with the density 1 g / cm 3 , which has the same rate of descent as the particle to be considered.
the rate of descent of the particle to be considered refers to still air.
the mass separator has a gravitational separator.
Gravity separators are usually designed as so-called crossflow or countercurrent separators.
the dust-laden gas flow undergoes a slowing down by the entry into the device and thus an increase in the residence time in the system.
cross-flow separator cross-flow separator
countercurrent separator countercurrent separator
a centrifugal separator can also be used as a mass-flow separator.
the flow is caused to rotate due to its own velocity after entering the device.
the particles suspended in the gas are partially separated due to the centrifugal force acting on them.
the mass separator may also have an inertial separator.
inertial separators which are also called “Umlenkabscheider”
flows are deflected such that the particles suspended in the gas can not follow the flow movement and are deposited. Frequently, obstacles are built into the deposition apparatus.
Air separation is a mechanical separation process in which particles are separated by their ratio of inertial and / or gravitational force to flow resistance in a gas stream. It is a classification process and uses the principle of gravity or centrifugal separation. Fine particles follow the flow, rough the mass force.
a device can be used which is already in the DE 10 2006 035 260 A1 is described. The content of this patent application is incorporated in full in the present application.
the combustion device has a combustion chamber of a waste incineration plant.
the waste to be incinerated can be burned on a combustion grate and thereby transported in the direction of the Entschlackervoriques.
the waste to be incinerated can also be burned in a fluidized bed.
the slag can be transported in the slagger towards the separator. This is particularly preferably done by means of a plunger.
the Entschlackervoriques is filled in operation with slag, that the passage between the incinerator and separator is filled with slag.
the ultrafine fraction can be supplied to the combustion apparatus with ambient air and / or with recirculation gas.
the ultrafine fraction can also be supplied to the flue gases of the combustion device of a dust separator.
the ultrafine fraction can also be fed to a separate, controlled disposal.
the object underlying the invention is also achieved with a device for processing slag of a combustion device, wherein the device comprises a slagging device and a separator, wherein the slagging device has a slag access and a slag outlet and separates the separator from the combustion device and wherein the separator in a arranged space having a Schlackezu Glassö Maschinen, an air supply opening, a Feinstfr reliesab Chinaö réelle and a residual slag removal opening.
the ultrafine fraction discharge opening may lead to a dust collector which is designed as a fabric filter or preferably as a cyclone.
the apparatus 1 for processing slag 2 of a combustion apparatus 3 shown has a slagger 4 and a separator 5.
the slagger 4 has a slag access 6 and a slag outlet 7.
the slagger separates the combustor 3 from the separator 5.
the separator 5 is arranged in an enclosed space 8, which is designed as an accessible cabin.
This space 8 has a slag feeder 9 following the slag outlet 7, an air supply opening 10 for supplying ambient air 11, a fine fraction discharge opening 12 and a residual slag discharge opening 13 arranged on a wall, not shown, lying in the drawing sheet plane.
the Feinstfr forcingsab Chinaö réelle 12 leads via a line 14 to a dust collector 15, which is designed as a cyclone.
the heavy particles are removed and the residual dust is supplied via line 16 and a blower 17 of the secondary combustion zone 18 of the combustion device 3.
the polymer matrix in which the carbon fibers are embedded burns.
the dust separator 15 is of the ultrafine fraction 24 means Centrifugal force a dust fraction 26 deposited and the rest is supplied with the secondary combustion air 27 of the secondary combustion zone 18 of the combustion device 3.
the slag thus migrates from the end of the combustion grate 21 in the Entschlacker 4 and is there conveyed by means of a plunger 27 to the separator 5.
the purger 4 is filled with slag such that the passage 28 between the incinerator 3 and the separator 5 is filled with slag 2.
the separator 5 is designed as an air classifier.
the fine particles of ultrafine fraction 24 follow the flow of the supplied ambient air 11 and the coarse particles follow the mass force and are discharged as residual slag 25.
the slag 2 is conveyed to cascade-like successively arranged moving plates 29 to 32, wherein in each case during the fall from one plate to the other plate and during the promotion on a plate by means of the air flow 33 of the ambient air 11 dust is removed from the residual slag 25, which is conveyed as ultrafine fraction 24 via the line 14 to the separator 15.
the plates 29 to 32 are driven by a motor with eccentric 34 and are mounted on the frame 35 by means of the spring 36.
