Abstract:
The invention relates to a device for treating a flowing fluid, in particular water, including a housing with an inlet for supplying the fluid and an outlet for discharging the fluid, an element for generating radiation, in particular UV radiation, the radiation at least acting on a part of the flowing fluid, and a means for influencing the fluid flow within the housing wherein the means for influencing the fluid flow is configured as a module with a large number of structured metal sheets.
Abstract:
An internal static mixing system such as a disperser of mesh wire or expanded metal co-knit with a multi filament material selected from inert polymers, catalytic polymers, catalytic metals or mixtures in combination with a vertical reactor having a reaction zone and the disperser disposed in said reaction zone, particularly for carrying out paraffin alkylation using acid catalyst is disclosed. The wire mesh provides the structural integrity of the system as well as the open space required in reactors for the movement of vapors and liquids though the system. The disperser may be in sheets, bundles or bales or positioned within a frame.
Abstract:
A liquid distributor for packed or filled columns having a multiplicity of horizontal layers involved in heat transfer or mass transfer. At least one layer of the column has an increased density by comparison with the other layers and is designed specifically for flooding. The specific surface can be greater than the specific surface of the underlying layers by a factor of 1.5 to 10.
Abstract:
A packing element for mass transfer column or towers and/or heat transfer columns or towers through which a gas and/or a liquid flows, is provided herein. The packing element possesses a plurality of exchange surfaces. The exchange surfaces of the packing element are formed by the surfaces of half-wave-shaped strips or wave-shaped strips. The packing element also possesses at least one first group of strips containing at least one half-wave-shaped strip or wave-shaped strip having a first periodic length, and at least one second group of strips adjoining thereto and containing at least one half-wave-shaped or wave-shaped strip having a second periodic length. Preferably, at least one outer side of the packing element is formed as a boundary element joining at least some of the strips of a group of strips.
Abstract:
A separation column (12) for an emission control system, the column including: an exhaust gas inlet (41) for receiving polluted exhaust gases therethrough; a first packed bed (37) at a predetermined first level above said exhaust gas inlet; first liquid distribution means (39) above said first packed bed for distributing liquid onto said first packed bed; a second packed bed (38) at a predetermined second level below said exhaust gas inlet; second liquid distribution (40) means below said first packed bed and above said second packed bed for distributing liquid onto said second packed bed; cooling means (46) between said second liquid distribution means and said second packed bed for cooling liquid from said second distribution means and entrained exhaust gases; an exhaust gas outlet (35) above said first packed bed for discharging cleaned exhaust gases therethrough; and a contaminated liquid outlet (36) below said second packed bed.
Abstract:
The invention relates to a liquid distributor for packed and/or filled columns, comprising individual, in particular horizontal layers involved in heat and/or material exchange. At least one layer of the column has a flooding, in particular for obtaining an increased density and for creating an accumulation of liquid and a specific surface for distributing the liquid. Said surface is greater than the surface of the overlying and underlying layers by a factor of 1.5 to 10, preferably by a factor of 2 to 3.
Abstract:
A combination splash/trickle pack for an evaporative cooler, which comprises packing elements 10,12 made from expanded metal or plastics sheets. The packing elements 10,12 are arranged such that in use they form a stack of packing elements within the cooler with the width and length of the packing elements determining the width and depth of the pack. Each of a plurality of the elements 10,12 has an inclined surface with an angle of inclination which varies so that in use a first region of the surface is sufficiently inclined to the horizontal to serve as a trickle surface and a second region of the surface is sufficiently close to the horizontal to serve as a splash surface.
Abstract:
Metal vapor-liquid contact plates disposed in face-to-face contact with respective corrugations inclined to the horizontal across an open notional plane. The metal packing is disposed within a vapor-liquid contact column for the purpose of bringing about mass and heat transfer between liquid and vapor passing in opposite directions therethrough. The body portion of each metal plate comprises metal that has been slitted to provide both surfaces thereof with a very large number of apertures with little wasted material. The metal lands defining the apertures are, moreover, twisted and angulated. The apertures in the plates also trap liquid and expose it to the vapor stream on both sides of the metal affording self-spreading of the liquid and turbulent vapor flow therethrough. In this manner, the assembly affords optimal pressure drop characteristics, surface to vapor passage area ratio, and vapor-liquid distribution characteristics. The laminate plate formation may also afford select flow and turbulence characteristics through capillary action between offset laminate land areas of the corrugated sheets.
Abstract:
A gas/liquid fill assembly for use in an evaporative cooling tower, chemical scrubbing apparatus or other device includes a plurality of facially-opposed corrugated sheets of material disposed in a substantially vertical, parallel relationship. The corrugations of each sheet are disposed at an angle to the horizontal with each of the corrugations extending continuously in substantially straight lines from one edge of the sheets to another edge. The corrugations in alternate sheets cross the corrugations in the sheets disposed between the alternate sheets. Adjacent corrugated sheets form channels to allow a gas and gravitating liquid to pass through the fill assembly. The sheets are formed of a foraminous material comprising an open-mesh network of interconnected webs. The interconnected webs are arranged to define a plurality of polygonally shaped openings. Each opening is symmetrically formed about an axis thereof and arranged within the sheet material so that its axis of symmetry is oriented substantially in the direction of maximum slope. The polygonally shaped openings in the sheets cause the gravitating liquid to divide around the openings and travel along the interconnecting webs whereby the liquid is distributed over the surfaces of the sheets.
