Abstract

Gaseous contaminants of air extracted by means of fans from lacquering and drying cabins are brought to condensation by an artificial or natural temperature gradient.

Description

Die Erfindung betrifft ein Verfahren zur Reduktion von gasförmigen luftverunreinigenden Stoffen in Emissionen und Immissionen aus Lackier- und Trockenkabinen.The invention relates to a method for reducing gaseous air pollutants in emissions and immissions from painting and Drying booths.

Üblicherweise werden zur Reduktion von gasförmigen luftverunreinigenden Stoffen in Emissionen und Immissionen aus Lackier- und Trockenkabinen die thermische Nachverbrennung, die Absorption durch Aktivkohle, bzw. die biologische Abluftreinigung als Verfahren eingesetzt.Usually used to reduce gaseous air pollutants Substances in emissions and immissions from painting and drying booths thermal afterburning, absorption by activated carbon, respectively biological exhaust air purification used as a process.

Bei diesem neuen Verfahren werden die gasförmigen luftverunreinigenden Schadstoffe durch ein künstliches oder natürliches Temperaturgefälle zum Kondensieren gebracht und mittels Wasservorhang aus der Abluft abgeschieden. Die praktische Umsetzung des Verfahrens wird am Beispiel einer Lackierkabine mit wassergefluteten Abluftfiltern beschrieben.With this new process, the gaseous air pollutants Pollutants caused by an artificial or natural temperature gradient Condensed and separated from the exhaust air with a water curtain. The practical implementation of the process is shown using the example of a painting booth described with water-flooded exhaust air filters.

Im Spritzbetrieb wird Zuluft mittels Ventilator angesaugt und über einen Lufterhitzer der Spritzkabine in der vorgewählten Temperatur zugeführt. Die durch den Spritzvorgang verunreinigte Luft wird über wassergeflutete Filtermatten aus der Kabine abgesaugt und mittels Kreuzwärmetauscher gekühlt zu einem Kondensatkühler geleitet. In diesem Kondensatkühler werden die nun kondensierten Schadstoffe mittels Wasservorhang aus der Abluft entfernt und zur vorhandenen Abscheideranlage der Spritzkabinen-Filter-Wasserspülung geleitet. Die gereinigte Abluft wird mittels Ventilator über Dach geführt. Das belastete Schadstoffkondensat wird entsprechend den jeweiligen technischen Regeln entsorgt. Dieses Verfahren öffnet auch kleineren Gewerbebetrieben die Möglichkeit Schadstoffreduzierung mit wirtschaftlich vertretbarem Investitionsaufwand zu betreiben.In spraying mode, supply air is drawn in by means of a fan and via a Air heater supplied to the spray booth at the preselected temperature. The Air contaminated by the spraying process is passed over water-flooded filter mats sucked out of the cabin and cooled to one using a cross heat exchanger Condensate cooler directed. They are now in this condensate cooler condensed pollutants removed from the exhaust air using a water curtain and existing separator system of the spray booth filter water rinse headed. The cleaned exhaust air is led over the roof by a fan. The contaminated condensate is determined according to the respective technical Rules disposed of. This process also opens up small businesses Possibility of reducing pollutants with economically justifiable To invest.
