Abstract: A method for extracting process air loaded with overspray from a coating plant, which includes leading overspray picked up by an air stream as process air along a flow path to a conditioning device. The process air is led on the flow path through at least one replaceable flow module having an inlet opening and an outlet opening, on the inner surfaces of which overspray can be deposited and, after a limiting loading with overspray has been reached, can be replaced by an unloaded flow module. An apparatus for extracting process air loaded with overspray having at least one replaceable flow module having an inlet and an outlet opening arranged in the flow path of the process air. On the inner surfaces of the flow module, overspray can be deposited. The flow module can be replaced with an unloaded flow module after a limiting loading with overspray is reached.

Abstract: A method for precipitating overspray from the overspray-laden booth exhaust air of coating installations, in particular from painting installations, the overspray is carried by an air stream to a precipitation device, where a majority at least of the solid material is precipitated from the overspray. The overspray-laden booth exhaust air is guided through filter modules, in which overspray is precipitated and which are designed as replaceable one-way components having a filter housing and a filter unit, wherein each filter module is replaced by an empty filter module after reaching a loading overspray. Moreover, the invention relates to a device for precipitating overspray by means of such one-way filter modules, and to an installation for coating objects, in particular vehicle bodies.

Abstract: A device for separating overspray from the cabin exhaust air of painting systems includes at least one separating surface, on which the exhaust air is guided and which is connected to a pole of a high voltage source. An electrode device arranged in the air stream is associated with the separating surface and connected to the other pole of the high voltage source. The separated paint overspray is transported away from the separating surface with a separating fluid, which flows over the separating surface-from top to bottom. A discharge device having a channel open at the top is present, from which the separating fluid exits along the longitudinal extension of the discharge device when the level of the separating fluid in the channel exceeds an exit level, and reaches the separating surface such that the separating fluid flows downward on the separating surface as a substantially adhering layer.

Abstract: The invention relates to a method for operating a system for producing bioethanol, wherein organic waste products of the production process, particularly DGS and DDGS, are combusted and the useful heat is fed back into the system itself. The combustion process takes place in a fluidized bed oven. All areas in which the combustion process takes place have sufficient heat removed that the melting point of the ash of the waste product, particularly 70° C., is not exceeded at any point. In this manner, a fine-grained ash forms and largely mixes into the fluidized bed and is easily disposed of. The useful heat is obtained partially from the flue gas arising from the combustion, and partially from the heat extracted from the combustion process for maintaining the maximum temperature.

Abstract: A device for separating paint overspray from the air of painting cubicles that is laden with overspray has in a housing at least one separating element, the surface of which is electrically conductive and is connected to one terminal of a high-voltage source. The separating element is assigned an electrode arrangement, which is connected to the other terminal of the high-voltage source. The air of the cubicle is made to flow past the separating element and the electrode arrangement in such a way that the overspray particles are colonized and deposited on the surface of the separating element. The separating element is moved continuously or intermittently, wherein a wiping device wipes off the overspray that is on the surface of the separating element. This can then be carried away by a suitable transporting device for disposal or re-use.

Abstract: An apparatus for treating workpieces comprises a treatment chamber enclosing a treatment zone for workpieces. A conveyor guides workpieces through the chamber. Said conveyor comprises drive elements located outside the chamber, and a carrier arm, extending through a slot along the conveyor's path of motion, in a wall of the chamber. A sealing arrangement comprises a first set of spring strips, which overlap laterally and are attached on one side of the slot to the wall, and an opposing second set of spring strips attached on the other side of the slot to the wall. In a resting position, the end zones of the spring strips overlap. Two deflecting devices, which move together with the carrier arm by the conveyor, open the sealing arrangement proximate the carrier arm by resiliently bending apart the spring strips. After passage of the carrier arm, the spring strips return to a sealing position.
