The invention relates to an insert element for inserting into a device for humidifying, cleaning and/or cooling a fluid, in particular a gas, such as, for example, air, said insert element comprising an insert body (10) which can be wetted with a liquid, in particular water, and through which a gas, in particular air, can flow and which has a flow inlet side and a flow outlet side and, between said sides, is provided with regions which can be wetted by the liquid and can be exposed to the fluid. The insert body (10) has a multi-layered design and has a number of undulated grid-type plate elements (12) which bear against one another, are limited by an edge (14, 16) and are provided with elevations and depressions. A film-type plate element (19, 19) is mounted between at least two adjacent grid plate elements (12). The film-type plate element (19, 19) is perforated.

A system for removing fine particulate matter from an aerosol, which, using a fine particulate matter capture device (1) comprising sheet members (2) parallel to each other and an interferent (3) between the sheet members, causes the aerosol to form a turbulent flow in passages between the sheet members (2), settles fine particulate matter in the aerosol on the outer surfaces of the sheet members under the action of turbulent fluctuation, thermophoretic force and/or vapor pressure gradient force, and meanwhile forms a water film on the outer surfaces of the sheet members (2) to prevent settled particulate matter from being carried away again by an air flow. The system is able to effectively remove fine particulate matter from an aerosol, especially sub-micron particulate matter, and significantly reduce the number concentration thereof.

Provided are a chevron vane that traps and removes droplets contained in steam and a moisture separator including the same. The chevron vane for trapping and removing droplets contained in steam includes a main frame group including multiple main frames arranged in a flow direction of steam and pivotably connected to each other, and a collection vane group mounted on the main frame group and including multiple collection vanes for trapping droplets contained in the steam.

A louvered separator for separating water from an air flow is provided which includes a number of vertical slat structures having a constant profile, horizontally spaced from each other so as to form horizontally tortuous separating channels in the spaces between the slats. The slat structures include water-collecting troughs and two separate slats having differing constant profiles; in the air flow direction a foremost front slat and a following back slat. The front slat includes, in the flow direction, a leading edge, a middle area and a trailing edge, and the back slat includes, in the flow direction, a leading edge, a middle area and a trailing edge. The water-collecting trough is limited to the area of the trailing edge of the back slat, so that the front slat entirely, and the back slat for more than a half of its length from the leading edge towards the trailing edge, form only even surfaces to guide the flow.

A baghouse apparatus for removing particulates from a 100% recycled asphalt pavement dryer exhaust air stream includes a drop out zone section having a water spray operable to initially drench an incoming air exhaust stream with water droplets while increasing air stream velocity, then slow the air stream velocity to cause drop out of particulates >1000 m from the slowed waste air stream, and collect the particulates dropped out of the waste air exhaust stream. The apparatus also includes a cyclonic scrubber section for further cooling the waste air exhaust stream while subjected the stream to a further water spray to condense aerosol vapor into droplets, a prefilter filtration section operable to collect and remove condensed aerosol droplets from the waste air stream; and a coalescing filtration section operable to remove 99% of remaining particulates from the waste air stream before discharge of the air stream to atmosphere.

A liquid film dust arrester is installed to face a gas flow containing dust and flowing out from a gas discharge pipe. The arrester includes a gas flow blocking unit arranged vis--vis the gas flow, a liquid dispersion unit having a dispersion section arranged at a position near the center of the gas flow blocking unit and upstream relative to the gas flow blocking unit as viewed in the flowing direction of the gas flow so as to face the gas flow blocking unit, a liquid ejection unit having an ejection port disposed vis--vis the dispersion section and configured to eject liquid from the ejection port, and a liquid film forming unit. The dispersion section comprises a smooth surface that causes the ejected liquid to flow and disperse on the smooth surface, and the liquid film is formed to face the gas flow flowing through the flow path.
