Abstract
Description
Die Erfindung betrifft eine Anlage zur Rückgewinnung von Wärmeenergie aus Rauchgasen in Kombination mit der Reinigung dieser Rauchgase von feuerungstechnischen Anlagen insbesondere für den Einsatz in Bäckereien, wobei diese Anlage in die Abgasführung zwischen Rauchgas- und Schwadenabgang eines Backofens und dem diese Gase ins Freie führenden Schornstein eingeordnet wird.The The invention relates to a plant for the recovery of heat energy from flue gases in combination with the purification of these fumes from Firing systems, especially for use in bakeries, being this plant in the exhaust system between flue gas and steam outlet of a baking oven and this Gases leading to the outdoors Chimney is arranged.
Allgemein ist es bekannt, daß bei derartigen feuerungs-technischen Anlagen der Energiebedarf durch Wärmerückgewinnung erheblich reduziert werden kann. Bekannte Backöfen, die unter Verwendung von Wärmetauschern mit der Rückgewinnung von Abwärmeenergie arbeiten, weisen jedoch die Problematik auf, daß nach dem Durchströmen der Wärmetauscher-Phase das Rauchgas oftmals extrem abgekühlt ist, so daß ein hoher Anteil an Kondensat vorhanden ist und die Kaminanlage nicht mehr den erforderlichen Abzug der Rauchgase aufbringen kann.Generally it is known that at such firing-technical installations of the energy requirement Heat recovery can be significantly reduced. Known ovens made using heat exchangers with the recovery of waste heat energy work, but have the problem that after flowing through the Heat exchanger phase The flue gas is often extremely cooled, so that a high Share of condensate is present and the chimney no longer can apply the required deduction of the flue gases.

Die Aufgabe der Erfindung besteht darin, eine Anlage zur Rauchgasreinigung und Wärmerückgewinnung für feuerungstechnische Anlagen, die als Beistellgerät zwischen wenigstens dem Rauchgasabgang der Verbrennungsstelle und dem diese Gase ins Freie führenden Schornstein einsetzbar ist, zu schaffen, mit der die vorgenannten Nachteile beseitigt werden.The The object of the invention is a system for flue gas cleaning and heat recovery for firing technology Plants that serve as a side dish between at least the flue gas outlet of the combustion site and which leads these gases into the open air Chimney is used to create, with which the aforementioned Disadvantages are eliminated.
Durch die Ausführung als eine beistellbare Anlage, die direkt mit dem Rauchgasabzug der feuerungstechnischen Anlage verbunden ist, kann auf aufwendige Kaminsysteme bzw. auf Kaminsanierungen verzichtet werden, da das Abgas nach Durchströmen der Anlage mit einem hohen Reinigungsgrad direkt ins Freie geleitet werden kann.By execution as an add-on facility that connects directly to the flue gas exhaust Combined firing system can be based on complex fireplace systems or to refrain from Kaminsanierungen, since the exhaust after flowing through the Plant with a high degree of purification led directly to the outside can be.
Erfindungsgemäß wird diese Aufgabe durch die im Anspruch 1 angegebenen kennzeichnenden Merkmalen gelöst.According to the invention this Task by the characterizing features specified in claim 1 solved.
Der wesentliche Vorteil der Erfindung besteht darin, daß Rauchgas und Schwaden durch von einander getrennte Wärmetauscher geführt werden, durch Einspritzen von Harnstoff bereits vor dem bzw. im Eingangsbereich des Wärmetauschers die Stickoxide minimiert werden und sowohl im Wärmetauscher als auch in anschließendem Scheibenwäscher Feststoffe abgeschieden werden. Weitere Giftstoffe werden in einem sich daran anschließenden Bereich neutralisiert. Dadurch ist es möglich, die Abluft ohne aufwendige Schornsteine, Essen oder dergleichen direkt ins Freie zu leiten. Die Ablufttemperatur weist aufgrund der Wärmerückgewinnung nur noch ein sehr niedriges Temperaturniveau auf.Of the essential advantage of the invention is that flue gas and swaths are guided by separated from each other by heat exchangers Injecting urea before or in the entrance area of the heat exchanger the nitrogen oxides are minimized and both in the heat exchanger and in subsequent washer washer solids be deposited. More toxins will be in one at it subsequent Neutralized area. This makes it possible, the exhaust air without consuming Run chimneys, food or the like directly into the open air. The exhaust air temperature has due to the heat recovery only a very low temperature level.
Vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung sind aus den übrigen Unteransprüchen und aus dem nachfolgend an Hand der Zeichnungen prinzipmäßig beschriebenen Ausführungsbeispiel ersichtlich.advantageous Further developments and refinements of the invention are evident from the remaining subclaims and from the principle described below with reference to the drawings embodiment seen.
