  • Patent number: 9546830
    Abstract: A composite hanger grid for supporting splash bars in a cooling tower uses separate vertical suspension members and horizontal beams by which all of the operational loads imposed on the splash bars are transferred to the horizontal beams, which then transfer the load to the vertical suspension members. Since all of the horizontal beams are independent of each other and separate components from the vertical suspension members, the horizontal beams will be loaded equally throughout the entire hanger grid. Also disclosed are components of the composite hanger grid, splash bars adapted for use with specific embodiments of the composite hanger grid, assemblies of the composite hanger grid with its supported splash bars, a method of assembling a composite hanger grid and a method of assembling an evaporative cooler fill assembly, including hanger grids and splash bars, in a cooling tower.

  • Patent number: 9403139
    Abstract: A mixing device for mixing concurrently-flowing streams of vapor and liquid in a vessel contains flow baffles forming a tangential inlet orifice through which the liquid and vapor streams flow at high flow velocity and in a tangential direction into a swirl box. The high momentum of the streams in the inlet orifice, the tangential direction of the streams, and the large distance between the inlet orifice and the vessel centerline, result in a violent swirling flow and a large number of fluid rotations in the swirl box, thereby thoroughly mixing the streams entering through the inlet orifice. A mixed stream of vapor and liquid exits the mixing device through an outlet opening in the bottom of the mixing device. An impingement plate located below the outlet opening spreads the liquid and decreases the velocity of the mixed stream. The temperature and chemical composition of the mixed stream are equilibrated.

  • Patent number: 8158073
    Abstract: A mass-exchange contact device is proposed, comprising an upper tray, contact element including a barbotage unit configured as an inner cap with strips tangently bent out, a lower tray, a casing including a ring-shaped descending limiter, windows circumferentially disposed on the casing's walls (lower row), orifices circumferentially disposed on the casing's walls (upper row) above the windows, a double-acting valve composed of an upper and lower plates fixedly attached to a distance rod, and a cover bushing disposed coaxially to and around the upper region of casing embracing the contact element. Embodiments comprise a number of rows of the proposed devices situated one above the other, and separated by multi-layer packing fittings. In catalytic distillation columns, the fittings can be filled with catalytic material. Alternatively, the fitting is substituted with a grating that supports a catalytic granular layer. The device allows improving operation, reliability, durability, reducing its weight and costs.

  • Publication number: 20120038069
    Abstract: The invention relates to a modular flow system comprising a plurality of frame elements which can be combined by means of welded web structures to various stacks comprising in each case at least two, in particular at least ten frame elements, in order to form different functional units such as in particular a membrane distillation stage, a steam generator, a condenser, a heat exchanger, a filter and/or a pervaporation stage. The frame elements according to the invention comprise in each case an outer frame provided with passage openings and vapour and/or fluid channels as well as a central inner region surrounded by the outer frame. Moreover, each frame element is provided on both sides with a welded web structure that delimits, on the one hand, the region comprising the passage openings and the central inner region and, on the other hand, at least two regions, each comprising a vapour and/or fluid channel.

  • Publication number: 20110305616
    Abstract: Vapor-liquid contacting apparatuses comprising a primary contacting zone and a secondary contacting zone are disclosed. A representative secondary contacting zone is a secondary absorption zone, such as a finishing zone for subsequent contacting of the vapor effluent from the primary contacting zone to further remove impurities and achieve a desired purity of purified gas exiting the secondary absorption zone. The secondary contacting zone is disposed below the primary contacting zone, such that the secondary contacting zone, which must operate efficiently in removing generally trace amounts of remaining impurities, is more protected from movement than the more elevated, primary or initial contacting stages for bulk impurity removal. The apparatuses are therefore especially beneficial in offshore applications where they are subjected to rocking.

  • Publication number: 20110210457
    Abstract: [Technical Problem] A contactor is provided which is capable of making fluids of two phases contact each other under a good dispersion state and which can be easily multi-staged. [Means for Solving the Problems] The inside of a contactor 1 is divided into a plurality of cells 22, 32 by partition walls (a vertical wall 10, horizontal walls 21, 31) and the respective cells 22, 32 become countercurrent contacting spaces of an upflow fluid flowing up in the contactor 1 and a downflow fluid flowing down in the contactor 1. A downflow fluid injection hole 52 provided in the vertical wall 10 of each stage makes the downflow fluid blocked by the partition wall and residing inject into the neighboring cells 22, 32 of a lower stage side, while an upflow fluid flow-in port 51 provided in an upper side of the injection hole 2 makes an upflow fluid from the cells 22, 32 of the lower stage side flow in.

  • Patent number: 7722708
    Abstract: An indoor air purification apparatus and method includes a watertight chamber including a top portion having a water inlet, a first air portal, a second air portal, a bottom portion, and a plurality of shelves mounted between the top portion and the bottom portion. Water continuously flows from the water inlet at the top of the chamber, typically falling over the shelves to a reservoir. Typically, a water pump returns the water to the water inlet at the top portion of the chamber through at least one conduit leading from the reservoir. An air pump typically drives the room air through the chamber from one air portal to the other and back into the room. The room air is purified as it mixes with the water cascading over the shelves.
