Abstract

The flue gases from thermal power stations which leave at a temp. of 140-180 degrees C are first freed of chlorides and dust in a scrubber. The residual contents of SO2, NOX, HF and other toxic substances are removed by a biological soil, filter. This filter consists of alkaline layers of soil which pref. have been made less compact by admixtures of humus, compost, peat, straw, sawdust or wood shavings. These additions have phosphate, dibasic carboxylic acid and N contg. material added to them, and the filter is impregnated with cultures. Absorptive or porous materials such as expanded clay or perlite may also be added. This ensures that the contaminants are adsorbed and retained by the soil filter and that environmental pollution is prevented.

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

'Biologische Sorption über Erdtilter, vorzugsweise für Kraftwerksabgase' Es ist bekannt, Abgase aus Kraftwerken zur Beseitigung von S02 über Rauchgastrockenabsorptions-Anlagen oder Rauchgaswaschanlagen zu leiten und nach der Reinigung über Kamine der Atmosphäre zu übergeben.'Biological sorption via soil filters, preferably for power plant exhaust gases' It is known to remove exhaust gases from power plants by means of dry smoke absorption systems or flue gas scrubbing systems and, after cleaning, the atmosphere via chimneys to hand over.

Der Aufwand für die Anlagentechnik ist beträchtlich und bedeutet eine Belastung von etwa 1 Pfg. bis 1,5 Pfg.The effort for the system technology is considerable and means a Load of about 1 to 1.5 pounds

pro erzeugte kwh.per kWh generated.

Nachstehend wird erfindungsgemäß eine Vorrichtung und ein Verfahren beschrieben, das mit wesentlich geringerem Aufwand umweltfreundlich die Schadstoffe abbaut.Apparatus and a method in accordance with the present invention are described below described, the environmentally friendly pollutants with much less effort degrades.

Die Rauchgase werden mit der Ausgangstemperatur von z.B. 140 - ~18000 vorzugsweise in einem Vorwäscher von Chloriden und Staub befreit.The flue gases are with the initial temperature of e.g. 140 - ~ 18000 preferably freed of chlorides and dust in a pre-washer.

Das vorgereinigte Abgas mit den Restschadstoffen S02 NOx 111? und ähnlichen Schadstoffen wird in einen biologischen Erdfilter eingeleitet.The pre-cleaned exhaust gas with the residual pollutants S02 NOx 111? and similar pollutants will turn into a biological earth filter initiated.

Dieser Eräfilter besteht vorzugsweise aus alkalischen Erdschichten, die mit Humus, Kompost, Torf, Stroh, Sägemehl oder Holzspänen und absorptiven, porösen Stoffen wie Blähton und Perlite aufgelockert sind, wobei diesen Stoffen Phosphate, zweibasische Karbonsäuren und stickstoffhaltige Verbindungen zugesetzt werden.This Eräfilter consists preferably of alkaline earth layers, those with humus, compost, peat, straw, sawdust or wood chips and absorptive, porous Substances such as expanded clay and perlite are loosened, with these substances being phosphates, dibasic carboxylic acids and nitrogen-containing compounds are added.

Durch diese Mischung ist die Gewähr gegeben, daß die obig angeführten Schadstoffe sich an das biologische Erdfilter anlagern und absorbiert werden.This mixture guarantees that the above-mentioned Pollutants attach themselves to the biological earth filter and are absorbed.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, ein Verfahren zur Beseitigung der Schadstoffe hinter Kraftwerken oder anderen Energieerzeugeranlagen bzw.Of course, the invention is not limited to the above in detail The forms of training described are limited, but there are numerous changes possible, but without deviating from the basic idea, a method for elimination the pollutants behind power plants or other energy generating systems or

abgaserzeugenden Anlagen zu verwenden, wobei ein Erdfilter aus den obigen zusammengesetzten Stoffen die Sorption übernimmt, und das Gas umweltfreundlich aus dem Erdfilter ohne Kamin entweicht, und der Erdfilter vorzugsweise mit Kulturen bepflanzt ist.to use exhaust gas generating systems, with an earth filter from the The above compound substances take over the sorption, and the gas is environmentally friendly escapes from the earth filter without a chimney, and the earth filter preferably with cultures is planted.
