Definitions
- the invention relates to a method for incinerating waste.
- it relates to a method for incinerating waste, in which one can largely avoid pollution by chlorine-containing and sulfuric acid exhaust gases by suitable selection of certain additives without the need for expensive and complex devices for gas scrubbing or exhaust gas filter systems.
- Garbage i.e. both household waste and industrial waste are burned to a large extent. The thermal energy of the waste is used and essentially a slag remains, which is placed in suitable landfills.
- Combustion gases generally contain contaminants from the waste and the combustion-promoting fuels, such as coal or heavy oil, in particular harmful SO 2 .
- the combustion exhaust gas released into the atmosphere is distributed in the atmosphere and is absorbed by rain and returns to the earth's surface as "acid rain”.
- the object of the invention is to demonstrate a method for incinerating waste in which the formation of gaseous pollutants during combustion is largely suppressed. Associated with this task is to modify the garbage to be incinerated by means of suitable additives in such a way that the development of gaseous pollutants in the combustion chamber and the emission of pollutant-containing emissions to the atmosphere are prevented while maintaining certain combustion conditions.
- the invention is based on the consideration that the development of the pollutants inevitably arising in waste incineration plants is suppressed already in statu nascendi. Because the additives prevent the formation of the pollutants under the conditions prevailing in the combustion chamber and they accumulate in harmless form in the slag, complex gas washing and dedusting systems can be dispensed with.
- the residue products from the sugar industry can be used individually or in combination.
- Component ii) increases the crystallization of the slag and component iii) contributes to the combustion.
- the ratio of calcareous aggregate (component a)) to the residue product from the sugar industry (component b)) - depending on the type of waste composition - can vary in a relatively wide range. It is generally about 30 to 70% by weight of component a) and 70 to 30% by weight of component b) and preferably about 45% by weight of component a) and about 55% by weight of component b).
- these are added in amounts of 5 to 15, preferably about 6 to 8%, based on the weight of the waste.
- the additives are expediently fed into the waste funnel when the waste is added.
- the free-flowing aggregate is applied to the rubbish by inflating it, whereby a good and thorough and uniform mixing or wetting of the rubbish surface with the aggregate is important.
- the mixing can be carried out in conventional mixing plants, e.g. B. done in tumble mixers. Conventional concrete mixers are quite suitable for this.
- the temperature in the combustion or combustion chamber In order to prevent the generation of harmful exhaust gases in the combustion chamber, it is necessary to monitor the temperature in the combustion or combustion chamber closely. This temperature must be between 850 and 950 ° C to avoid thermal dissociation after chemical setting.
- the combustion is preferably carried out at about 900.degree.
- the process according to the invention which consists on the one hand in the selection of the additives to be added to the combustion waste and on the other hand in the exact maintenance of the exact temperature in the combustion chamber, not only effectively reduces the pollutant emissions considerably, but also gives a slag which is problem-free in terms of wastewater technology.
- the slag crystallizes as a result of the addition. It contains chemical compounds of sulfur as well as the heavy metals in bound form. The slag can be deposited easily. However, it can also be used in road construction or in the construction industry if it is appropriately refurbished.
Abstract
Description
Die Erfindung betrifft ein Verfahren zum Verbrennen von Müll. Sie betrifft insbesondere ein Verfahren zum Verbrennen von Müll, bei dem man durch geeignete Auswahl von bestimmten Zuschlagsstoffen eine Umweltverschmutzung durch chlorhaltige und schwefelsaure Abgase weitgehend vermeiden kann, ohne daß teure und aufwendige Vorrichtungen für eine Gaswäsche oder Abgasfilteranlagen erforderlich sind.The invention relates to a method for incinerating waste. In particular, it relates to a method for incinerating waste, in which one can largely avoid pollution by chlorine-containing and sulfuric acid exhaust gases by suitable selection of certain additives without the need for expensive and complex devices for gas scrubbing or exhaust gas filter systems.
Müll, d.h. sowohl Hausmüll als auch Industriemüll wird in großem Maße verbrannt. Dabei wird die Wärmeenergie des Mülls genutzt und es bleibt im wesentlichen eine Schlacke übrig, die man in geeigneten Deponien unterbringt.Garbage, i.e. both household waste and industrial waste are burned to a large extent. The thermal energy of the waste is used and essentially a slag remains, which is placed in suitable landfills.
Von ausschlaggebender Bedeutung beim Betrieb einer Müllverbrennungsanlage sind die mit den Verbrennungsgasen an die Umwelt abgegebenen Emissionswerte..Die Verbrennungsgase enthalten in der Regel aus dem Müll und den die Verbrennung fördernden Brennstoffen, wie Kohle oder Schweröl stammende Verunreinigungen, insbesondere schädliches S02. Das in die Atmosphäre abgegebene Verbrennungsabgas verteilt sich in der Atmosphäre und wird durch Regen aufgenommen und kommt als sogenannter "Saurer Regen" auf die Erdoberfläche zurück.Of crucial importance in the operation of a waste incineration plant are the emission values released to the environment with the combustion gases Combustion gases generally contain contaminants from the waste and the combustion-promoting fuels, such as coal or heavy oil, in particular harmful SO 2 . The combustion exhaust gas released into the atmosphere is distributed in the atmosphere and is absorbed by rain and returns to the earth's surface as "acid rain".
Der Schaden, der durch den sogenannten "Sauren Regen" erfolgt, insbesondere das allmähliche Absterben der Wälder, ist unermeßlich. Deshalb bestehen gesetzliche Vorschriften, durch welche die zulässigen Schadstoffemissionen von Müllverbrennungsanlagen festgelegt sind.The damage caused by the so-called "acid rain", especially the gradual death of the forests, is immeasurable. That is why there are legal regulations that determine the permissible pollutant emissions from waste incineration plants.
Für Müllverbrennungsanlagen ist es ebenso bekannt wie für Großfeuerungsanlagen, daß man die Verbrennungsabgase, bevor sie an die Atmosphäre abgegeben werden, reinigt. Diese Abgase, die neben SO2, Chlor- und Fluorwasserstoffemissionen als Hauptbestandteile enthalten, müssen,bevor sie an die Atmosphäre abgegeben werden, durch entsprechende Einrichtungen gereinigt werden. Während ältere Müllverbrennungsanlagen keinerlei Vorkehr für die Reinigung der Abgase enthielten, sind in jüngerer Zeit erstellte Müllverbrennungsanlagen mit entsprechenden Gaswäschern und Staubfiltern ausgerüstet. Die Wirksamkeit einer Gaswäsche ist jedoch noch nicht voll befriedigende und um den gesetzlichen Anforderungen entsprechend niedrige Schadstoffemissionswerte zu erzielen, müssen gewaltige Investitionen vorgenommen werden. Ältere Müllverbrennungsanlagen müssen nachträgtlich mit entsprechenden Reinigungsvorrichtungen ausgerüstet werden.It is known for waste incineration plants as well as for large combustion plants that the combustion exhaust gases are cleaned before they are released into the atmosphere. These exhaust gases, which contain SO 2 , chlorine and hydrogen fluoride emissions as the main components, must be cleaned before they are released into the atmosphere by appropriate facilities. While older waste incineration plants did not contain any precautionary measures for cleaning the exhaust gases, waste incineration plants recently built have been equipped with appropriate gas scrubbers and dust filters. However, the effectiveness of a gas scrubber is not yet completely satisfactory and huge investments have to be made to achieve low pollutant emission values in accordance with legal requirements. Older waste incineration plant must be retrofitted with appropriate cleaning devices.
Es wäre sehr vorteilhaft, wenn man die Schadstoffemissionen von Müllverbrennungsanlagen durch geeignete Maßnahmen von vornherein so niedrig halten könnte, daß aufwendige Gaswaschanlagen vermieden werden können.It would be very advantageous if the pollutant emissions from waste incineration plants could be kept so low from the outset by suitable measures that complex gas scrubbing plants could be avoided.
Aufgabe der Erfindung ist es, ein Verfahren zur Müllverbrennung aufzuzeigen, bei dem man schon das Entstehen der gasförmigen Schadstoffe während der Verbrennung weitgehend unterdrückt. Verbunden mit dieser Aufgabe ist es, den zu verbrennenden Müll durch geeignete Zuschläge so zu modifizieren, daß bei Einhaltung gewisser Verbrennungsbedingungen die Entwicklung von gasförmigen Schadstoffen im Verbrennungsraum und die Abgabe von schadstoffhaltigen Emissionen an die Atmosphäre unterbunden wird.The object of the invention is to demonstrate a method for incinerating waste in which the formation of gaseous pollutants during combustion is largely suppressed. Associated with this task is to modify the garbage to be incinerated by means of suitable additives in such a way that the development of gaseous pollutants in the combustion chamber and the emission of pollutant-containing emissions to the atmosphere are prevented while maintaining certain combustion conditions.
Diese Aufgabe wird durch das Verfahren der Erfindung gelöst.This object is achieved by the method of the invention.
Der Erfindung liegt die Überlegung zugrunde, daß die Entwicklung der in Müllverbrennungsanlagen zwangsläufig entstehenden Schadstoffe schon im statu nascendi unterdrückt. Dadurch, daß man durch die Zusatzstoffe unter den Bedingungen, die im Verbrennungsraum vorherrschen, das Entstehen der Schadstoffe verhindert und diese in unschädlicher Form in der Schlacke gebunden anfallen, können aufwendige Gaswasch- und auch Entstaubungsanlagen entfallen.The invention is based on the consideration that the development of the pollutants inevitably arising in waste incineration plants is suppressed already in statu nascendi. Because the additives prevent the formation of the pollutants under the conditions prevailing in the combustion chamber and they accumulate in harmless form in the slag, complex gas washing and dedusting systems can be dispensed with.
Als Zuschlagsstoffe werden gemäß der Erfindung folgende Komponenten verwendet:
- l. Spezialkalk T aus der chemischen Industrie. Dieser Spezialkalk enthält im wesentlichen Calciumcarbonat (etwa 85 %) sowie 9 bis 11 % hexagonalen Kohlenstoff. Ein solcher Graphit- und kalkhaltiger Spezialkalk fällt z. B. bei der Kalkstickstoffherstellung in großen Mengen an und mußte bisher auf die Halde geworfen werden (Komponente a)).
- 2. Als zweite Komponente (Komponente b)) kommen Rückstandsprodukte aus der Zuckerindustrie zur Verwendung, nämlich
- i) sirupartige Melasse,
- ii) Festsubstanz aus der Rübenreinigung sowie
- iii) Carboschlamm aus der Zuckerfertigung.
- l. Special lime T from the chemical industry. This special lime essentially contains calcium carbonate (about 85%) and 9 to 11% hexagonal carbon. Such graphite and calcareous special lime falls z. B. in lime nitrogen production in large quantities and previously had to be thrown onto the stockpile (component a)).
- 2. As a second component (component b)) residue products from the sugar industry are used, namely
- i) syrupy molasses,
- ii) solid substance from beet cleaning and
- iii) Carbo sludge from sugar production.
Die aus der Zuckerindustrie stammenden Rückstandsprodukte können einzeln oder in Kombination eingesetzt werden. Die Komponente ii) erhöht die Kristallisation der Schlacke und die Komponente iii) trägt zur Verbrennung bei.The residue products from the sugar industry can be used individually or in combination. Component ii) increases the crystallization of the slag and component iii) contributes to the combustion.
Auch diese Stoffe, die in der Zuckerindustrie anfallen, galten bisher als Abfallstoffe, die nicht oder nur schlecht verwertbar waren.These substances, which are produced in the sugar industry, were previously considered waste that could not be used or could only be used with difficulty.
Es ist es möglich den kalkhaltigen Bestandteil des Zuschlagsstoffs und den Rückstand aus der Zuckerindustrie vorzumischen und dann in geeigneten Mengen dem Verbrennungsmüll zuzuführen, oder aber die Komponenten werden einzeln dem Verbrennungsmüll zugegeben.It is possible to premix the calcareous constituent of the additive and the residue from the sugar industry and then add it to the waste in suitable amounts, or the components are added individually to the waste.
Das Verhältnis von kalkhaltigem Zuschlagsstoff (Komponente a)) zu dem Rückstandsprodukt aus der Zuckerindustrie (Komponente b)) kann - je nach der Art der Müllzusammensetzung - in verhältnismäßig breitem Umfang variieren. Es liegt im allgemeinen bei etwa 30 bis 70 Gew.% der Komponente a) und 70 bis 30 Gew.% der Komponente b) und vorzugsweise bei etwa 45 Gew.% der Komponente a) und etwa 55 Gew.% der Komponente b).The ratio of calcareous aggregate (component a)) to the residue product from the sugar industry (component b)) - depending on the type of waste composition - can vary in a relatively wide range. It is generally about 30 to 70% by weight of component a) and 70 to 30% by weight of component b) and preferably about 45% by weight of component a) and about 55% by weight of component b).
Je nach der Müllbeschaffenheit und auch in Abhängigkeit von der Zusammensetzung des Zuschlagsstoffe werden diese in Mengen von 5 bis 15, vorzugsweise etwa 6 bis 8 %, bezogen auf das Gewicht des Mülls, zugegeben.Depending on the nature of the waste and also on the composition of the additives, these are added in amounts of 5 to 15, preferably about 6 to 8%, based on the weight of the waste.
Die Zuführung der Zuschlagsstoffe erfolgt zweckmäßiger Weise bei der Müllaufgabe in den Mülltrichter. Der rieselförmige Zuschlagsstoff wird durch Aufblasen auf den Müll aufgebracht, wobei eine gute und gründliche und gleichmäßige Vermischung bzw. Benetzung der Mülloberfläche mit dem Zuschlag wichtig ist.The additives are expediently fed into the waste funnel when the waste is added. The free-flowing aggregate is applied to the rubbish by inflating it, whereby a good and thorough and uniform mixing or wetting of the rubbish surface with the aggregate is important.
Werden die Zuschlagsstoffe vorher schon miteinander vermischt, so kann das Vermischen in üblichen Mischanlagen, z. B. in Taumelmischern erfolgen. Übliche Betonmischer sind hierfür durchaus geeignet.If the additives are mixed together beforehand, the mixing can be carried out in conventional mixing plants, e.g. B. done in tumble mixers. Conventional concrete mixers are quite suitable for this.
Die Zuführung kann auch direkt durch eine Betonpumpe in den Müllaufgabetrichter der Verbrennungsanlage erfolgen. Dabei erfolgt durch die Förderbewegung im Mulltrichter eine in den meisten Fällen ausreichende Vermischung mit dem Verbrennungsmüll.It can also be fed directly into the waste feed hopper of the incineration plant using a concrete pump. In most cases, the conveying movement in the gauze funnel ensures sufficient mixing with the combustion waste.
Um das Entstehen der schädlichen Abgase schon im Verbrennungsraum zu unterbinden ist es erforderlich, die Temperatur im Verbrennungs- bzw. Feuerungsraum genau zu überwachen. Diese Temperatur muß zwischen 850 und 950°C liegen, um nach der chemischen Abbindung keine thermische Dissoziation zu bekommen. Vorzugsweise wird die Verbrennung bei etwa 900°C durchgeführt.In order to prevent the generation of harmful exhaust gases in the combustion chamber, it is necessary to monitor the temperature in the combustion or combustion chamber closely. This temperature must be between 850 and 950 ° C to avoid thermal dissociation after chemical setting. The combustion is preferably carried out at about 900.degree.
Durch das erfindungsgemäße Verfahren, das einerseits in der Auswahl der dem Verbrennungsmüll zuzusetzenden Zuschläge und andererseits in der genauen Einhaltung der genauen Temperatur im Verbrennungsraum besteht, wird nicht nur wirksam die Schadstoffemission erheblich vermindert, sondern man erhält auch eine Schlakke, die abwassertechnisch problemlos ist. Durch den Zuschlag fällt die Schlacke kristallisiert an. Sie enthält eingeschlossen chemische Verbindungen des Schwefels sowie auch die Schwermetalle in gebundener Form. Die Schlacke kann problemlos deponiert werden. Sie ist aber auch bei entsprechender Aufarbeitung im Straßenbau oder in der Bauindustrie verwertbar.The process according to the invention, which consists on the one hand in the selection of the additives to be added to the combustion waste and on the other hand in the exact maintenance of the exact temperature in the combustion chamber, not only effectively reduces the pollutant emissions considerably, but also gives a slag which is problem-free in terms of wastewater technology. The slag crystallizes as a result of the addition. It contains chemical compounds of sulfur as well as the heavy metals in bound form. The slag can be deposited easily. However, it can also be used in road construction or in the construction industry if it is appropriately refurbished.

Ein Gemisch aus 90 Gew.% Hausmüll und 10 Gew.% Industriemüll (wobei der Industriemüll einen Anteil von 30 Gew.% Kunststoffen, einschließlich PVC enthielt) wurde kontinuierlich im Einfülltrichter vor dem Feuerraum mit
- 10 Gew.% Zuschlagsstoffen aus
- 45 Gew.% Spezialkalk T (85 % Calciumcar- bonat und 10 % hexagonaler Kohlenstoff)
- 35 Gew.% Carboschlamm
- 15 Gew.% Festsubstanz aus der Rübenreinigung
- 5 Gew.% Melasse
vermischt. Zusammen mit einem Schweröl wurde das Gemisch im Feuerraum der Verbrennungsanlage verbrannt, wobei die Temperatur auf 850°C eingestellt wurde. Ohne Zugabe der Zuschlagsstoffe ergab sich beim Verbrennen des Mülls eine Anfangsemission of 1.700 mg Cl/m und 400 mg SO2/m3. Nach mehrstündigem konstantem Betrieb ergab sich bereits nach ca. einer Stunde eine Verringerung der Emissionswerte um 80 bis 90 %. Die Emissionswerte stellten sich auf 180 bis 230 mg Cl/m3 und 75 mg SO2/m3 ein. Die Schlacke zeigte beim Abkühlen eine kristalline Struktur. Alle Schwermetalle sind der Schlacke eingebaut und die Eluate sind abwassertechnisch problemlos.A mixture of 90% by weight of domestic waste and 10% by weight of industrial waste (the industrial waste containing 30% by weight of plastics, including PVC) was continuously carried in the hopper in front of the combustion chamber
- 10% by weight of aggregates
- 45 wt.% Special lime T (85% Cal c iumcar- carbonate and 10% of hexagonal carbon)
- 35% by weight of carbon sludge
- 15% by weight solid substance from beet cleaning
- 5% by weight molasses
mixed. Together with a heavy oil, the mixture was burned in the combustion chamber of the incinerator, the temperature being set to 850 ° C. Without adding the additives, the incineration of the waste resulted in an initial emission of 1,700 mg Cl / m and 400 mg SO 2 / m 3 . After several hours of constant operation, the emission values were reduced by 80 to 90% after just one hour. The emission values were between 180 and 230 mg Cl / m 3 and 75 mg SO 2 / m 3 . The slag showed a crystalline structure on cooling. All heavy metals are built into the slag and the eluates are problem-free in terms of waste water technology.
