Definitions

  • the invention relates to a method and a device according to the preambles of claims 1 and 10.
  • Incinerators with rotary kilns are primarily designed and built to incinerate solid, pasty, muddy and viscous hazardous waste, i.e. extremely heterogeneous mixed waste that can be fed continuously, but mostly in batches and in many cases only in barrels, and their combustion in household waste incineration plants leads to problems would.
  • the molten slag is fed to a wet descaler at the end of the rotary kiln, below the afterburner.
  • a lance can be used to blow in air dust into the slag melt bath of the rotary kiln.
  • the aim of this proposal is to incorporate the dusts containing heavy metals into the slag from waste incineration.
  • An auxiliary burner which is operated with waste oil, can support the combustion process in the rotary kiln or in a second slag melt bath within the afterburning chamber.
  • the simultaneous fulfillment of these two requirements has so far only been possible through the use of large quantities of high-calorific, liquid waste that can be injected into the furnace via burners.
  • the combustion air is generally set constant for the waste that is not fed in through burners. Controlling the combustion air according to the oxygen requirement for optimal combustion has been tried several times, but has not met expectations.
  • the energy content and especially the burning behavior of the waste cannot be adequately estimated because the parameters energy content, proportion of inorganic material and water, lumpiness, melting behavior, ease of degassing, reaction surface, ignition friendliness and the like are rarely adequately determined in advance can.
  • a batch operation of an incineration plant generates peak loads after which the combustion air oxygen would have to be adjusted.
  • Liquid waste when fed through a burner larger
  • Batch waste in drums greater than 3.00.
  • a value of around 2.5 is generally set as the average combustion air excess in order to meet all conditions.
  • Excess combustion air of 2.75 - based on solid and semi-solid waste - can be calculated that at an exhaust gas temperature of 1250 ° C, only a portion of approx. 22% of the input energy resulting from the waste, based on the lower calorific value Hu, can be introduced into such a special waste incineration plant in the form of solid, muddy and pasty waste. The rest would have to be brought in as liquid waste or regular fuel. This is not economical.
  • these rotary kiln exhaust gases are transferred directly to an afterburning chamber, in which the temperature is then increased, if necessary, by supplying liquid or gaseous fuels, and a residual oxidation of the exhaust gases is carried out at a low exhaust gas velocity and a long residence time.
  • Rotary kiln of 1: 3.2 for example, can
  • This value depends, among other things, on a) the amount of exhaust gas and the exhaust gas temperature and the resulting exhaust gas velocity, b) the residence time in the rotary kiln, determined by furnace inclination, furnace speed, waste friction angle, waste and slag melting behavior, viscosity of the liquid slag, c) reaction area, for example determined through the grain size, the weight of the waste space, the proportion of inorganic material, waste melting behavior, the respective degree of filling in the individual furnace zones drying, degassing, combustion and post-combustion, d) and other parameters, such as B. the number and size of the abandoned barrels and waste batches, the proportion of slag fur builders, the proportion of salts and salt formers in the waste as well as the possibility of equalizing the waste dosage.
  • the invention provides for decoupling the partial objectives mentioned at the outset from one another in terms of process technology and plant technology.
  • the rotary kiln is operated via a controlled metering of combustion air in such a way that the inorganic waste components with additives, but also additional flue dust from the own exhaust gas cleaning system but also from external combustion systems, are obtained as viscous, glazed mass.
  • the suitable inorganic additives can be added directly to the combustion material and the airborne dusts to be melted in. The melting ensures that the slag burns out completely and the glazing and the inclusion of harmful substances (heavy metals) in the glass matrix minimize the water solubility as far as possible.
  • fly dusts are produced by other suitable organic additives, e.g. B. Waste bound. These bound fly dusts are fed directly into the rotary kiln melt from the transition housing.
  • fly dusts prepared with inorganic and organic additives melt suddenly and the volatile heavy metals contained therein are incorporated into the silicate matrix of the melt products.
  • This method and simultaneous selective application of combustion air also prevents the above-mentioned "freezing" of the slag when the cold dusts are added.
  • the furnace rotation also causes rapid mixing and incorporation into the glassy slag. Because the bound dusts are introduced at the furnace outlet, the dwell time at high temperatures is short. This also minimizes the evaporation of heavy metals.
  • melt As a controlled variable, it is accepted that the combustion takes place slightly above stoichiometric in the case of waste with a low calorific value and sub-stoichiometric in the case of waste with high calorific value. However, a substoichiometric driving style is preferred.
  • the ignition energy is only about 1.5 to 3 Gcal / h (6.0 to 12.5 GJ / h) liquid , waste that can be atomized via the burner or corresponding additional fuels are required
  • the exhaust gases from the rotary kiln are burned out in a rotary kiln transition housing and a downstream afterburning chamber, which have one or more narrowed, extremely high turbulence-generating cross-sectional constrictions that mix the exhaust gases optimally.
  • activated combustion air preheated to approx. 700 ° C, cutting the furnace exhaust gas stream and thereby further optimizing the mixing effect, can be blown in. In this way, optimal residual oxidation of the exhaust gases can be achieved in the first turbulence zone.
  • the inventive arrangement of the rotary kiln, the transition housing (rotary kiln delivery) and the afterburner chamber makes it possible to accelerate the exhaust gas flow in a narrowed cross section and to supply activated combustion air transversely to it.
  • This section of the furnace thus acts like a turbulence zone and has an effect right into the afterburning chamber for the remaining exhaust gas burnout.
  • This design has the advantage that in the rotary kiln itself there is no optimization of the exhaust gas burnout and the furnace temperature can be regulated depending on the desired slag melt flow, if necessary in the case of substoichiometric combustion.
  • the longitudinal axis offset arrangement of the rotary kiln • the post-combustion chamber makes it possible in the outlet of the rotary kiln, through an aperture in the transition housing, to introduce a slag smelting burner, the preheated, optionally under the action of combustion air is working. So you get another one Possibility to control the slag melt flow, especially with changing melting behavior, without influencing the combustion process in the rotary kiln.
  • the afterburning chamber can also have further cross-sectional constrictions, which improve the mixing effect between exhaust gas and supplied air or other substances to be burned.
  • a tangential introduction of the exhaust gases into the afterburning chamber can also contribute to this improvement.
  • the first turbulence zone and burner arrangement in the afterburning chamber is, in relation to the plant height, considerably lower than the last burner level in conventional hazardous waste incineration plants.
  • FIG. 1 A cross section through a Afterburner one
  • the Fig .- ⁇ shows in section a rotary kiln 1 and off-axis to an afterburning chamber 3, through a transition housing 2 and
  • Transition cross-sectional constriction 2a are connected to one another.
  • the rotary kiln exhaust gases pass through the housing 2 to the narrowed chamber section 2a. There, the exhaust gases are accelerated and swirled through the opening 4 by blowing in activated combustion air, so that they are thoroughly mixed and burned out in the cross-sectional constriction and afterburner chamber.
  • a burner can also be installed in the inlet opening 4. Additional burners and combustion air inlets can be used in the tangentially arranged inlet openings 5 of the afterburning chamber 3.
  • An additional opening 6 has a double function. On the one hand, the
  • Airborne dust feeding device and an additional burner can be introduced into the outlet of the rotary kiln 1 and, if necessary, an air supply for additional combustion air can be installed in this opening 6.
  • a wet slipper 7 of the usual type is arranged for receiving and cooling the rotary kiln slag.
  • Fig. ⁇ . shows a section through the afterburning chamber 13 according to section III-III in Fig.,.
  • Exhaust gases emerging from the mouth 11 of the transition housing 12 are post-combusted in the chamber 13, optionally by metering in further fuels through the supply device 15 and supplying combustion air through the ring line 9 and nozzles (not shown) which open into the afterburning chamber 13.
  • Another cross-sectional constriction 14, i.e. second turbulence zone, with a transition to the exhaust gas channels 10 and 16 ensures that further intensive mixing takes place and coarse fly ash and melted ash are deposited in the container 8.
  • the advantages of the invention lie in the possibility of optimally vitrifying slag and dusts, optimally burning off exhaust gases from the incineration plants, minimizing the formation of nitrogen oxides in the exhaust gas, increasing the rotary kiln throughput, and drastically reducing the need for liquid waste and / or additional fuels.

Abstract

Un procédé et un dispositif nouveaux servent à brûler des déchets spéciaux et à fondre (vitrifier) des cendres volantes en même temps. A cet effet, la consommation des scories et des gaz perdus est effectuée séparément, selon des procédés industriels différents. La température du four tubulaire tournant est réglée par adjonction d'air de combustion, selon la température des scories fondues, le cas échéant par combustion sous-stoechiométrique. La consommation des gaz perdus se fait par adjonction d'air activé de combustion ou d'oxygène dans des zones de haute turbulence d'aggrégats complémentaires. Des agents vitrifiants peuvent être ajoutés au four tubulaire tournant. Les cendres volantes sont liées à des substances énergétiques et ajoutées directement aux scories fondues à la sortie du four tubulaire tournant, de sorte que leur fonte soudaine, leur mélange intime et leur liaison aux scories du four sont assurées par la rotation du four. En outre, il est important de noter que l'exploitation sous-stoechiométrique permet de réduire radicalement les besoins en déchets liquides et/ou en combustibles supplémentaires, d'augmenter la performance du four tubulaire tournant et de réduire la formation de NOx.
