Abstract
Vorrichtung zur Schadstoffentfernung aus Rauchgasen von Kleinfeuerungsanlagen, dadurch gekennzeichnet, dass im Rauchgasstrom mindestens 2 durch Leitbleche getrennte Wärmetauscher nebeneinander installiert sind, über die abwechselnd mit dem einen Tauscher Wärme zwecks Unterschreitung des Wassertaupunktes entzogen und direkt dem anderen Tauscher zur Wasserverdampfung aus dem abzusprengenden Belag zugeführt wird.contraption for pollutant removal from flue gases from small combustion plants, characterized in that in the flue gas stream at least 2 by baffles separate heat exchangers are installed side by side, over alternating with the one exchanger heat in order to undercut deprived of the Wassertaupunktes and directly to the other exchanger for water evaporation is supplied from the abzusprenenden coating.
Description
Im Gegensatz zu industriellen oder gewerblichen Wärmeerzeugern werden Haushalts-Kleinfeuerungsanlagen individuell und nicht immer vorgabegemäß betrieben. Oft zahlreich in Wohngebieten installiert emittieren sie bei relativ geringen Schornsteinhöhen zunehmend gesundheitsrelevante Schadstoffmengen. Zur Einhaltung vorgegebener Grenzwerte kann allerdings bereits eine anteilige Schadstoffentfernung ausreichen!in the Contrary to industrial or commercial heat generators Household small combustion plants are individual and not always operated by default. Often numerous in residential areas They emit at relatively low chimney heights increasingly health-relevant pollutant quantities. To comply with However, predetermined limits can already a proportionate removal of pollutants enough!
Bisher sind zumindest bei Haushaltsfeuerungen praktisch keine zusätzlichen Rauchgasreinigungsvorrichtungen im Einsatz, weil die bewährten Rauchgasreinigungsverfahren dafür noch zu großen technischen oder finanziellen Aufwand bedingen.So far are at least at home firings practically no additional Flue gas cleaning devices in use, because the proven flue gas cleaning process for that too big technical or financial Expenditure condition.

Es
ist bekannt, dass sich an feuchten Flächen verstärkt
Asche, Feinstaub sowie saure Gase abscheiden und solche durch Unterschreiten
des Wassertaupunktes entstehen können. Unkontrollierbare
Anbackungen sind jedoch in einem Dauerbetrieb nicht hinnehmbar,
da sie schwerwiegende Ausfalle provozieren. Die Rauchgase werden
deshalb möglichst über dem Wassertaupunkt gehalten
oder wiederaufgeheizt (

Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, aus dem Rauchgas in einer kleinen, ohne besondere Sachkenntnis zu betreibenden Feuerungsanlage möglichst unkompliziert einen Teil der Schadstoffe abzuscheiden.Of the in claim 1 protection invention is based on the problem out of the flue gas in a small, with no special expertise too operating furnace as uncomplicated as possible Part of the pollutants.
Dieses Problem wird mit dem in Schutzanspruch 1 aufgeführten Merkmalen gelöst.This Problem is with the features listed in protection claim 1 solved.
Mit der Erfindung wird erreicht, dass der Effekt der verstärkten Abscheidung von Rauchgasschadstoffen an feuchten Oberflächen auch in kleinsten Feuerungsanlagen ohne technisch anspruchsvolle Zusatzeinrichtungen außer der gesteuerten Wärmeträgerförderung verwertbar ist.With the invention is achieved that the effect of reinforced Separation of flue gas pollutants on moist surfaces even in the smallest combustion plants without technically demanding Additional equipment apart from the controlled heat transfer medium is usable.
Angesichts gleichzeitiger anteiliger Rauchgasreinigung führt die zusätzliche Wärmeauskopplung und damit die Verringerung des Netto-Wärmeverlustes in Summe nicht zu negativen Auswirkungen auf die Immissionssituation der Quellenumgebung. Die Vorrichtung kann als Teil der Neuanlage oder typunabhgängig nachträglich installiert werden.in view of simultaneous proportionate flue gas cleaning leads the additional Heat extraction and thus the reduction of the net heat loss in sum, not to have a negative impact on the immission situation the source environment. The device can be part of the new plant or can be retrofitted on a type-neutral basis.
Eine vorteilhafte Ausgestaltung der Erfindung ist im Schutzanspruch 2 angegeben. Damit lassen sich Abscheidegrad und Abgasparameter weiter optimieren.A advantageous embodiment of the invention is in the protection claim 2 specified. This allows further optimization of the degree of separation and exhaust gas parameters.
