Description
Lufterhitzer mit einem drehbaren, in Sektorkammern eingeteilten Wärmetauscher Die Erfindung betrifft einen Lufterhitzer mit einem drehbaren, in Sektorkammern eingeteilten Wärmetauscher, bei welchem die jeweils durch heiße Gase aufgeheizten Kammern nachher von uer zu erhitzenden Luft durchströmt werden und eine Abreinigung von Staub durch Dampf oder Preßluft erfolgt. Die in den heißen Rauchgasen enthaltenen Staubmengen, die sich in den Lamellen des Wärmetauschers absetzen, werden bei dem Durchtritt der Luft mitgerissen und verunreinigen diese somit. Für gewisse Zwecke, wie Verwendung der erhitzten Luft als Unterwind für Feuerungen, dürfte die Staubbeimengung nicht von erheblichem Nachteil sein. Will man sie jedoch für unmittelbare Raumbeheizung benutzen, so wäre dies infolge der Staubbeimengungen nicht möglich. Es bestände hier nun die Möglichkeit, die gesamte Luft durch ein Filter zu schicken. Eine solche Anlage würde jedoch infolge der erheblichen Luftmengen, die zu bewältigen sind, sehr teuer werden. Gemäß der Erfindung ist ein weiterer Sektor in den Arbeitsgang eingeschaltet, der sogenannte Reinigungssektor. Dieser Reinigungssektor befindet sich, in der Drehrichtung gesehen, hinter dem Heizgassektor und vor dem Luftsektor. Die hier abgeblasene Staubluft wird zu einer Filteranlage geführt. Es ist hier also nur eine kleine Filteranlage notwendig. Die durch das Filter gereinigte, ebenfalls erhitzte Luft läßt sich dann wieder mit der übrigen erhitzten Luft vereinigen, weil dieselbe als staubfrei gelten kann.Air heater with a rotatable heat exchanger divided into sector chambers The invention relates to an air heater with a rotatable, in sector chambers divided heat exchanger, in which each is heated by hot gases The chambers are then flowed through by the air to be heated and a cleaning process of dust takes place through steam or compressed air. Those contained in the hot smoke gases Amounts of dust that settle in the fins of the heat exchanger are used in the Entrained passage of air and thus contaminate them. For certain purposes like the use of the heated air as an underwind for furnaces, the addition of dust is likely not be of significant disadvantage. However, if you want them for immediate room heating use, this would not be possible due to the dust. It would exist here now the possibility to send all the air through a filter. Such However, due to the considerable amount of air that has to be handled, the system would become very expensive. According to the invention, another sector is in operation switched on, the so-called cleaning sector. This cleaning sector is located seen in the direction of rotation, behind the heating gas sector and in front of the air sector. The dust air blown off here is fed to a filter system. So it is here only a small filter system is necessary. The one cleaned by the filter, too heated air can then be reunited with the rest of the heated air because the same can be considered dust-free.
In der Zeichnung stellt die Fig. t einen solchen Lufterhitzer in Ansicht dar, die Fig. z im Grundriß, und die Fig. 3 zeigt eine solche Anlage in Verbindung mit einem Filter und Ventilator. Es bezeichnet a das Gehäuse, b die einzelnen drehbaren Zellen, cr, c2 und c3 die Wände der drei Sektoren, nämlich W den Sektor für den Durchtritt der heißen Gase, R den Sektor für die Reinigung und K denjenigen für die Luft d bezeichnet die Preßluftleitung, f eine Abklopfvorrichtung, e die Saugleitung zum Filter. In der Fig.3 bezeichnet g das Filter, h die Verbindungsleitung vom Filter zum Ventilator, i den Saugventilator, k die -Druckleitung des Ventilators, l bezeichnet den Staubaustritt des Filters.In the drawing, FIG. T shows such an air heater in view, FIG. Z in plan view, and FIG. 3 shows such a system in connection with a filter and fan. A denotes the housing, b the individual rotatable cells, cr, c2 and c3 the walls of the three sectors, namely W the sector for the passage of hot gases, R the sector for cleaning and K that for the air d denotes the compressed air line , f a knocking device, e the suction line to the filter. In FIG. 3, g denotes the filter, h the connection line from the filter to the fan, i the suction fan, k the pressure line of the fan, l denotes the dust outlet of the filter.
