  • Patent number: 10094579
    Abstract: An evaporative HVAC apparatus is disclosed. In at least one embodiment, the apparatus provides an at least one housing having an inner surface that defines a substantially tubular-shaped air passage extending therethrough. An absorbent wicking layer is formed immediately adjacent to at least a portion of the inner surface of the housing, and a thermal layer is formed immediately adjacent to an inner surface of the wicking layer. The housing also provides an at least one fluid inlet aperture through which a fluid line extends a distance into the housing so as to be in fluid communication with the wicking layer. Thus, a fluid is selectively delivered to the wicking layer through the fluid line which, in turn, permeates the thermal layer and evaporates into the air located immediately adjacent an exposed inner surface of the thermal layer, thereby affecting the temperature of the air moving through the air passage.

  • Patent number: 8919745
    Abstract: A foam generating apparatus provides a high-quality mixing of solution and air to produce foam without restricting the flow of liquid through apparatus. An air manifold has passages allowing the flow of water or solution through the apparatus and also features apertures that introduce pressurized air in a parallel flow with the water or solution introduced into the exit chamber. The cross-sectional area of the passages is at least as great as the water or solution inlet, and thus the device does not significantly restrict flow of liquid, even in the case where a straight flow of water or solution without mixed air is desired.

In some embodiments, the elements may have: a ratio of surface area of the interaction zone to surface area of the flow through zone between 1:0.5 and 1:3; and the interaction zone surface area occupies between 45% and 70% of the open face surface area.

  • Patent number: 7431804
    Abstract: A process is proposed for the distillation or reactive distillation of a mixture that includes at least one toxic component, the process being carried out in a column containing a structured packing, having at least one packing layer (1) having a lower end (2) and an upper end (3), the packing layer having an internal geometry varying over its height, in such a manner that in the distillation or reactive distillation, in a first, lower region (6) of the packing layer (1) a bubbling layer having a predominantly disperse gas phase can be established and simultaneously in a second, upper region (7) of the packing layer (1) a film flow having a predominantly continuous gas phase can be established.

  • Patent number: 7422197
    Abstract: A divided wall exchange column includes a dividing wall strengthened by stiffening members and/or a double wall design to better withstand pressure differentials and minimize temperature differentials. When a double wall is used, cost of manufacture and installation is minimized by reducing the manufacturing tolerances required while providing a design robust in construction, installation, and operation. When structured packing is used, the stiffening members, combined with positioning the layers of packing at preferred angles relative to the dividing wall, result in minimal interference with the heat and/or mass transfer process while minimizing the complexity of manufacture and construction of the packing. Further, by positioning the top layer of structured packing at other preferred angles relative to the dividing wall, a simplified liquid distributor design may be used in the divided wall exchange column while the layers below may still be orientated as described above with all the associated benefits.

  • Patent number: 7278628
    Abstract: Apparatus for dosing gaseous and/or vaporous substances An apparatus for dosing gaseous and/or vaporous substances, in particular for generating varying scents, includes a multitude of packaged storage containers (1) from which different gases and/or vapors are driven out by a carrier medium. On their inlet sides, the storage containers are connected to a common carrier medium manifold (13) via a shut-off device (4) assigned to each storage container that can be actuated, and on their outlet sides to a joint homogenization chamber (8). Both the carrier medium manifold and the homogenization chamber are connected to a carrier medium source using a regulating valve (5, 9). Check valves (6, 7) are integrated in the gas passages to the storage container and from the storage container to the homogenization chamber. A dosing apparatus designed based on this principle is characterized by low space requirements and materially separate volume flows that can be exactly timed and dosed.

  • Patent number: 7267329
    Abstract: An assembly in an exchange column includes a plurality of generally vertically adjacent layers of structured packing. Each layer includes a plurality of generally horizontally adjacent structured packing elements, each of which has an upper edge and a lower edge. Each layer has a top having a plurality of the upper edges and a bottom having a plurality of the lower edges. In a first layer of packing at least one of the upper edge and the lower edge is modified on at least one element. In a second layer of the packing, located vertically adjacent the first layer, the upper edges and the lower edges are unmodified on substantially all of the elements, whereby one of the unmodified upper edge and the unmodified lower edge on at least one of the elements in the second layer is adjacent one of the modified edges in the first layer.
