Abstract: An impact test apparatus can be used to determine particle interfacial energies with varying relative air humidity. It was observed that capillary condensation increased the adhesive forces of hydrophilic materials. A systems humidity separation window was identified and the differences in interfacial energy for a hydrophilic surface and for a hydrophobic surface can be exploited in order to achieve the separation of particles. Separation and concentration of particles, particularly particles within a mineral ore body, can be obtained.

Abstract: The present invention involves a fabrication of ventilation-fan-ammonia-gas-removal-device and dual-function-ammonia-gas-removal-and-air-cooling-equipment for application to livestock confined facilities. The former is installed on the wall of livestock confined facilities to remove ammonia gas from ventilating air and the latter is installed inside the livestock confined facilities to remove ammonia gas and to cool air, suspending from the ceiling of livestock confined facilities. They are fabricated by assembling several plastic-rod-screen-fills which are made with plastic rods. Water supplied from the top of devices, flowing down on the surface of rods, cools air or absorbs ammonia gas and water vapor by contacting with air traveling transversely to the descent of water on the surface of plastic rods by means of forced draft.

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: A scrubber for separation of liquid phase and any other constituents from a fluid now that in substance includes a gas. The scrubber is formed as a standing vessel with round cross section, with an outlet for liquid from the bottom and an outlet for gas from the top. The scrubber is distinguished in includes a fluid inlet that either is tangentially oriented relative to the inner wall of the scrubber or equipped with a deflection plate, such that introduced fluid is directed tangentially horizontal or with a small downward slope along the inner wall of the scrubber, into and through a fluid way arranged as a downwards directed spiral within the scrubber, along the inner wall, from a level over or at the inlet to a level at or close to the outlet for liquid, with an opening for gas escape inwards toward the center of the scrubber. The scrubber according to the invention results in very low liquid entrainment.

Abstract: A process for separating carbon dioxide from a fluid containing carbon dioxide, NO2, and at least one of oxygen, argon, and nitrogen comprises the steps of separating at least part of the fluid into a carbon dioxide enriched stream, a carbon dioxide depleted stream comprising CO2 and at least one of oxygen, argon, and nitrogen and a NO2 enriched stream and recycling said NO2 enriched stream upstream of the separation step.

Abstract: Gas scrubber, with at least one drop separator level which spans a cross section of the gas scrubber, the gas scrubber comprising at least one edge rest and a plurality of carrying beams, spanning the cross section, for the mounting of drop separators which jointly delimit a free flow cross section of the gas scrubber, at least 95% of the free flow cross section being designed with throughflow drop separators. This is achieved preferably in that drop separators are used having a plurality of drop separator lamellae which are arranged at an inclination to one another and are fixed by means of at least two end plates of unequal level or non-parallel.

Abstract: An air washer adsorbs outside contaminated air to disks, which have water films formed thereon, and settles contaminants in water in a water reservoir, thus purifying and humidifying air.

Abstract: A method for collecting airborne particles and microorganisms by injecting them into a swirling air flow from where they are removed onto a dry surface, a surface coated with an adhesive material or a surface wetted by a liquid that is swirled onto that surface from a liquid reservoir below. The swirling air motion and the aerosol injection into it are achieved by pushing or drawing the airborne particles and microorganisms through one or more nozzles that are directed at an angle towards the collection surface.

Abstract: An apparatus for collecting airborne particles and microorganisms by injecting them into a swirling air flow from where they are removed onto a dry surface, a surface coated with an adhesive material or a surface wetted by a liquid that is swirled onto that surface from a liquid reservoir below. The swirling air motion and the aerosol injection into it are achieved by pushing or drawing the airborne particles and microorganisms through one or more nozzles that are directed at an angle towards the collection surface. Each entire nozzle or only its exit section are aligned along the axis of aerosol flow injection into the swirling air flow. The apparatus consists of one piece or of three main components that are assembled to form one unit and are comprised of one inlet section, one nozzle section, and one collection vessel.

Abstract: The invention concerns a scrubber for cleaning work area exhaust air polluted with particles, in particular exhaust air containing particles of paint from a paint spray booth. The scrubber has a flow duct (5), defined in cross section by two opposite duct walls (7). The flow duct (5) includes an inlet region (4) into which the polluted exhaust air flows and into which a fluid (16), running along the duct walls (7), is introduced. The flow duct (5) terminates downstream in an outlet nozzle (3) which runs, transversely to the general flow-in direction (18), into the inlet region (4) and is formed between an upper (8) and a lower (9) duct wall section. A guide wall (2), which has at least one curved portion, tangentially adjoins the upper duct wall section (8), downstream of the outlet nozzle (3).
