  • Patent number: 8858667
    Abstract: The present invention relates to a coupling head for coupling a towing vehicle to a trailer. According to the invention, in the coupling head a filter element is used. The filter element is bypassed by a continuously open by-pass. Preferably, the path through the by-pass has at least one redirection in the region of an undercut. As a result of the redirection, contaminants in the compressed air are not or not fully transferred through the by-pass. The by-pass might also ensure a supply of compressed air to the trailer, for example, when the filter element is at least partly blocked due to the contaminants. According to the invention, a valve element used to open the by-pass in the case of increasing blockage of the filter element is not required.

    Abstract: A diffuser object for a flue gas desulfurization (FGD) absorber is described. The diffuser object is placed in a high flue gas velocity zone inside the absorber in order to better distribute the flue gas and improve absorption efficiency. A method of improving absorption efficiency in a FGD absorber is also described. The method involves identifying high and low velocity zones within the absorber and positioning diffuser objects within the high velocity zones in a non-packed manner. The placement of the diffuser objects and configuration of the objects are calculated to equalize flow rates within the absorber.

In the method the device with a gas layered sieve plate for wet desulfurization of flue gas, an absorbing liquid improves reacting conditions by effecting it own circulation without using additional power due to the structural characteristics possessed by the device and flue gas is treated very satisfactorily thanks to high gas-liquid contact efficiency. In order to minimize power consumption and the size of the device but promote desulfurization to an unusual degree, an absorber is divided into an upper froth layer and a lower liquid layer by a single-stage gas dispersing plate with a large number of gas ejection holes bored therein.

  • Patent number: 5641338
    Abstract: An air scrubber and method for cleaning a stream of air utilizes a horizontal tray (A) together with a passageway (B) for transporting air beneath the trays and directing same upwardly through a perforated bottom of the tray which is supplied with a predetermined level of water which flows over a weir from a suitable source (C) wherein the upwardly directed air agitates the water resulting in a scrubbing action which is then followed by the action of an eliminator section (D) which removes water remaining in the air stream after agitation and scrubbing.

  • Patent number: 5629258
    Abstract: A flat structural element has a plurality of openings which are distributed according to a predetermined pattern for use in packings. Every opening is delimited by the edges, which extend at an angle to each other or are curved. The structural element is made from two or more adjacent strips of flat material which are connected to each other with butt or overlapping connections.

  • Patent number: 5518668
    Abstract: An air stripper assembly includes a housing having at least one sieve tray operatively positioned therein. Each sieve tray is selectively removable from the housing. If more than one sieve tray is positioned within the housing, each is removable without a need to change orientation of any other sieve tray positioned within the housing. Thus, an operator can easily clean and maintain a selected sieve tray, without disassembling the entire assembly or affecting the location of other sieve trays.

  • Patent number: 5397381
    Abstract: In a method of cooling and scrubbing a hot gas a hot gas is supplied with a removal pipe into a scrubber. The hot gas is introduced into at least one liquid bath of the scrubber. The hot gas is forcibly dispersed to form small bubbles over at least a portion of a flow path of the hot gas through the liquid bath. The exterior of the removal pipe is cooled with liquid to be introduced into the liquid bath by guiding the liquid along the exterior of the removal pipe countercurrent to the flow of the hot gas in the removal pipe. The device for performing the method has at least one liquid bath. A removal pipe for removing hot gas from the combustion chamber and guiding it to the liquid bath is provided. At least one flow divider with a plurality of openings is arranged in the flow path of the hot gas. A gas removal device is positioned above the liquid bath for removing the cooled gas exiting from the liquid bath.
