Description

Ventilator-Saugzuganlage für Ventilator- und Ejektor-Saugzug. Die Erfindung bezieht sich auf eine Ventilator-Saug zuganlage, welche es gestattet, von Ejektor-Saugzug auf gewöhnlichen Saugzug überzugehen. Sie ist dadurch gekennzeichnet, daß ein Hilfsventilator in parallele Wirkungsweise mit einer beweglichen RohrabschluBvorrichtung gebracht ist, welche zwischen dem Kamin und den Düsen eingeschaltet ist.Induced draft fan system for induced draft fans and ejectors. the The invention relates to a fan suction system, which allows to switch from ejector induced draft to ordinary induced draft. It is characterized by that an auxiliary fan works in parallel with a movable pipe closure device is brought, which is switched between the chimney and the nozzles.

Die Zeichnung zeigt in senkrechtem Schnitt ein Ausführungsbeispiel der Erfindung.The drawing shows an exemplary embodiment in vertical section the invention.

Im Kamir. a ist die Düse b angeordnet, welche am Ausströmrohr c des Ventilators d des Ejektor-Saugzuges angebracht ist. Eine zweite Düse e ist vorteilhaft gleichachsig um die erste angebracht, könnte aber auch eine andere Lage im Kamin annehmen. Sie ist mit dein Ausströmrohr f des Hilfsventilators g verbunden. Eine bewegliche Abschlußvorrichtung h umgibt die Düse e, und es ist eine Bewegungsvorrichtung vorgesehen, die beispielsweise aus einer Kette und Rädern i, j, k besteht; diese dient dazu, die Abschlußvorrichtung in senkrechter Richtung zu verstellen, biss sie auf die Wand des Kamins trifft.In the Kamir. a , the nozzle b is arranged, which is attached to the outlet pipe c of the fan d of the ejector-induced draft. A second nozzle e is advantageously attached coaxially around the first, but could also assume a different position in the chimney. It is connected to your outlet pipe f of the auxiliary fan g. A movable closing device h surrounds the nozzle e, and a movement device is provided which consists, for example, of a chain and wheels i, j, k ; this is used to adjust the locking device in the vertical direction until it hits the wall of the chimney.

Ist bei bestehendem Ejektor-Saugzug die Abschlußvorrichtung h um die Düse e heruntergelassen, ,so wirken der Ventilator d oder Ventilator g für sich, und es wird nur ein Teil der Gase aus der Feuerung ausgesaugt, ,welche bei ihrem Austreten aus der Düse b oder e die Elektor-Saugwirkung im Kamin bestimmen. Für .die direkte Saugzugwirkung wird die Abschlußvorrichtung h in die mit punktierten Linien gezeichnete Stellung angehoben, bis sie den Raum zwischen der Düse e und dem Kanin abschließt. Ihr oberer Rand braucht sich nicht unbedingt gegen den engsten Querschnittdes Kamins anzulegen; die beiden Ventilatoren saugen dann zusammen alle Gase aus der Feuerung.If the closing device h around the nozzle e is lowered when the ejector suction is in place, the fan d or fan g work for themselves, and only some of the gases are sucked out of the furnace, which when they emerge from the nozzle b or e determine the Elektor suction in the chimney. For .die direct suction effect, the closing device h is raised in the position shown with dotted lines until it closes the space between the nozzle e and the rabbit. Its upper edge need not necessarily be placed against the narrowest cross-section of the chimney; the two fans then suck all the gases out of the furnace together.
