Description
Selbsttätige Regelvorrichtung für gasbeheizte Lacktrockenöfen Die Neuerung betrifft eine selbsttätige Regelvorrichtung für gasbeheizte Lacktrockenöfen mit wechselndem Gehalt an Lösungsmitteln in der Abluft, von der wenigstens ein Teil den mit üblichem Brenngas gespeisten Heizbrennern als Verbrennungsluft zugeführt wird. Automatic control device for gas-heated paint drying ovens Die The innovation concerns an automatic control device for gas-heated paint drying ovens with varying levels of solvents in the exhaust air, at least a portion of which fed to the heating burners fed with conventional fuel gas as combustion air will.
Um die lösungsmitteldampfhaltige Abluft bei Lacktrockenöfen nicht völlig ungenutzt als Portlaft ins Freie blasen zu müssen, verwendet man sie neuerdings : : als Verbrennungsluft für die mit üblichem Brenngas gespeisten Heizbrenner des Trockenofen.Not about the exhaust air containing solvent vapor in paint drying ovens To have to blow outdoors as a portlaft, completely unused, has recently been used :: as combustion air for the heating burners of the Drying oven.
Man spart dabei soviel an Brenngas ein, wie-im Verhältnis der Heizwerte-Lösungsmitteldampf in der Verbrennungsluft enthalten ist.This saves as much fuel gas as-in the ratio of the calorific value to solvent vapor is contained in the combustion air.
Die bisher für die Ermittlung des wechselnden Lösungsmitteldampfgehaltes in der Abluft und zugleich für das Regeln der Brenngaszufuhr zu den Heizbrennern verwendeten Geräte sind aber teuer und arbeiten vor allem recht träge.Previously for the determination of the changing solvent vapor content in the exhaust air and at the same time for regulating the fuel gas supply to the heating burners The devices used are expensive and, above all, work very slowly.
Gemäß der Neuerung wird die Funktion dieser bekannten Analysen-Kontroll-und Steuergeräte'von einem zusätzlichen, mit einem, Brenngas-Abluftgemisch von konstantem Mischungsverhältnis gespeisten Brenner sowie einer Einrichtung, wie Flammfühler oder dergleichen mit Verstärker, zum Überwachen der Flammentemperatur und zugleich zum Regeln der NN. den Heizbrennern des Trockenofen zuzuführenden Brenngasmenge und gegebenenfalls auch zum Regeln der als Fortluft ins Freie zu blasenden Abluftmenge übernommen.According to the innovation, the function of this known analysis control and Control devices' from an additional, with a, fuel gas / exhaust air mixture of constant Mixing ratio of the fed burner and a device such as a flame sensor or the like with amplifier, to monitor the flame temperature and at the same time to regulate the NN. The amount of fuel gas to be supplied to the heating burners of the drying oven and, if necessary, also to regulate the amount of exhaust air to be blown into the open as exhaust air accepted.
Diese nEUartige Regelvorrichtung ist nicht nur sehr einfach, sondern sie arbeitet auch praktisch trägheitslos und daher verläßlicher als die erwähnten bekannten Geräte, An einem in der Zeichnung schematisch dargestellten Aus führungsbeispiel wird die Neuerung im Folgenden genauer beschrieben : Der Brenner 1, zum Beispiel ein Treibluftbrenner, wird über die Leitung 2 mit einem üblichen Brenngas und über die Leitung 3 mit lösungsmitteldampfhaltiger Abluft gespeist, wobei das Mischungsverhältnis von Brenngas und Abluft konstant ist.This new type of control device is not only very simple, but it also works practically without inertia and therefore more reliably than the ones mentioned known devices, on an exemplary embodiment from schematically shown in the drawing the innovation is described in more detail below: The burner 1, for example a propellant air burner is via line 2 with a conventional fuel gas and via the line 3 is fed with exhaust air containing solvent vapor, the mixing ratio of fuel gas and exhaust air is constant.
In die Flamme des Brenners 1 ragt der stabförmige Flammfühler 4 hinein, der an den Verstärker 5 angeschlossen ist. Von diesem Verstärker 5 geht eine Steuerleitung 6 zu den Reglern für die Brenngaszufuhr zu den (nicht dargestellten) Heizbrennern des Ofens und gegebenenfalls noch die Steuerleitung 7 zu dem Fortluftregler.The rod-shaped flame sensor 4 protrudes into the flame of the burner 1, which is connected to the amplifier 5. A control line goes from this amplifier 5 6 to the regulators for the fuel gas supply to the heating burners (not shown) of the furnace and possibly also the control line 7 to the exhaust air regulator.
An Stelle des Flammfühlers kann auch ein Photoelement zum Überwachen der Flammentemperatur vorgesehen sein.Instead of the flame sensor, a photo element can also be used for monitoring the flame temperature.
Die Wirkungsweisdder neuartigen Regelvorrichtung ist so, daß jede Änderung des Lösungsmitteldampfgehaltes in der Abluft eine Änderung der Flammentemperatur des Zusatzbrenners 1 bewirkt, die dann über den Flammfühler 4 und den Verstärker 5 in Steuerimpulse für die Brenngasregler und, wie erwähnt, gegebenenfalls auch für den Fortluftregler-im allgemeinen eine einfache, wie die Brenngasregler durch Servomotor oder dergleichen betätigte Klappeumgewandelt wird.The mode of operation of the novel control device is such that each Change in the solvent vapor content in the exhaust air a change in the flame temperature of the additional burner 1 causes, which then via the flame sensor 4 and the amplifier 5 in control pulses for the fuel gas regulator and, as mentioned, possibly also for the exhaust air regulator - generally a simple one, like the combustion gas regulator through Servomotor or the like operated flap is converted.
Es ist leicht einzusehen, daß man die neuartige Vorrichtung auch ohne weiteres zum Regeln der Heizleistung der Heizbrenner des Ofens verwenden kann.It is easy to see that the novel device can also be used without can use further to regulate the heating power of the heating burner of the furnace.
