Abstract: A method for separating overspray from the cabin exhaust air of coating systems, in particular of painting systems, which is laden with overspray, the overspray is taken up by an air flow and conveyed to an electrostatically operating separating device. There, the bulk at least of the solids is separated from the overspray at at least one separating surface. An electrically conductive material or material mixture is used as a separating agent, which is applied to the at least one separating surface of the separating device and at the operating temperature of the separating device has a wax-like consistency. Also a separating device with such a wax-like material and a system for coating articles.

Abstract: A system and method for controlling dust and/or odors comprises a blower unit and baffle member deployed downstream of the blower unit. The blower unit comprises a fan propelled mister with a discharge tube and a fan disposed in the discharge tube adapted for drawing air into the discharge tube and creating a high velocity air flow exiting therefrom. The discharge tube has a plurality of nozzles and a fluid source is placed in communication with the nozzles such that the nozzles discharge fluid particles that are entrained in a high velocity air flow exiting from the discharge tube distal end. A baffle member is deployed downstream of the blower unit at an elevation above the blower unit so as to alter a flow path of ambient air flowing through a discharge path of the blower unit.

Abstract: Embodiments of an abatement apparatus are disclosed herein. In some embodiments, an abatement apparatus may include a scrubber configured to receive an effluent stream from a process chamber and further configured to remove first particles from the effluent stream; a scrubber conduit coupled to the scrubber to receive the effluent stream therefrom and configured to remove second particles from the effluent stream, the scrubber conduit having one or more inlets configured to provide a fluid to sufficiently wet an interior surface of the scrubber conduit to trap the second particles thereon and to wash the second particles therealong; and a central scrubber coupled to the scrubber via the scrubber conduit. In some embodiments, the scrubber conduit is downward sloping from the scrubber to the central scrubber. In some embodiments, a plurality of scrubbers may be coupled to the central scrubber via a plurality of scrubber conduits.

Abstract: The present invention is directed to methods for carbon dioxide from air, which comprises exposing solvent covered surfaces to air streams where the airflow is kept laminar, or close to the laminar regime. The invention also provides for an apparatus, which is a laminar scrubber, comprising solvent covered surfaces situated such that they can be exposed to air streams such that the airflow is kept laminar.

Abstract: The present invention comprises an apparatus and method for efficiently venting impurities from a heat recovery steam generator system by concentrating the impurities in a condensing deaerating vent line 40 and then venting a proportionately small amount of steam with a proportionately high concentration of impurities. The condensing deaerating vent line 40 is attached to a low pressure drum 10, and feed water 54 may be added to the upper portion of the condensing deaerating vent line 40 to improve condensation and conserve thermal energy.

Abstract: An air cleaning apparatus draws air through a convoluted air channel defined by a plurality of non-permeable baffles. The baffles are arranged so that the air stream must change direction several times before exiting the apparatus. A fluid curtain is disposed along at least a part of the convoluted channel to remove particulate material from the air stream. One preferred embodiments causes fluid to flow over the baffles to provide a plurality of fluid curtains arranged along the air channel.

Abstract: A scrubber more effectively mixes air or gas with water or a liquid cleaning agent to entrain and thereby clean contaminants from an airflow. An improved baffle-defining structure forces a more complete interaction between the air and water and buffets the mixture into an air/water mixing zone while preventing the water from collecting on an inner surface of the water scrubber and draining down out of the airflow path. A cyclonic, centrifugal dewatering apparatus removes the mist and residual contaminants after the water scrubbing removes most of the contaminants from the air.

Abstract: Apparatus for removing odor from the air exhaust of animal confinement buildings is described. One embodiment of the apparatus includes a plenum housing attached to an existing exhaust fan on an animal confinement building. The plenum housing has an entrance and an exit, and houses a baffle having a roughened surface. Water is delivered to the baffle surface by spray headers which are configured to spray water from a top edge of the baffle. A water curtain is generated by spray nozzles at the plenum housing exit. A trough is configured to collect a water effluent from a bottom edge of the baffle. In use and according to the methods described, an air stream consisting of exhaust air from an animal confinement building is directed toward the water-flooded baffle surface. Odor particles in the air stream impinge on the baffle surface and are adsorbed by the water. The air stream continues to flow past the baffle surface and through the water screen at the plenum housing exit.

Abstract: A dry pump (32) has an inlet connected to the oven (10) for the purpose of establishing the desired low pressure conditions inside the oven and for extracting residual gas therefrom, a hydrolysis reactor (50) is connected to an outlet of the dry pump in order to receive residual gases coming from the oven, the hydrolysis reactor includes a first outlet (52) for solid deposits or for acid solutions coming from hydrolysis of the gases it receives, and it has a second outlet (54) for gas which is connected to the atmosphere. Gas injection means (46, 48) are located between the inlet of the dry pump (32) and the hydrolysis reactor (50) to prevent any backflow from the hydrolysis reactor towards the pump. Water feed means (74, 76) are connected to the hydrolysis reactor (50), at least via the second outlet (54) thereof, in order to put into solution the acid vapors that come from the hydrolysis reactor, thereby avoiding discharging them in the atmosphere.
