  • Patent number: 8602397
    Abstract: A cooling tower with a hot water distribution system includes a distribution lateral disposed above a hot water basin. The distribution lateral discharges fluid into the hot water basin, which in turn, releases the fluid through a plurality of orifices. As the fluid is released, it falls on heat-exchanging fill material that assists in increasing the cooling rate of the fluid. The distribution lateral is configured structurally to discharge the fluid through a plurality of outlets at one or more angles (as compared to the horizontal) into the hot water basins. In one embodiment, the outlets are arranged into one or more rows that extend along a substantial length of the distribution lateral. Discharging the fluid in this manner enhances and promotes a more even fluid flow within the hot water basin, which results in a more even fluid flow over and onto the fill material, thereby increasing thermal efficiency.

    Abstract: A system for removing contaminants from a gas in an exhaust stack. A cone structure having a plurality of stacked cones is located in the exhaust stack in combination with a spray system including a water input pipe with a misting spray nozzle. Air or gas containing contaminants flows in the exhaust stack. The water from the nozzle system mixes with the air or gas to form a mist. The cones of the cone structure are stacked and held by rods to create slight changes in the flow direction of the mist. The flow of the gases drive the condensed liquid to the outside perimeter of the cones and to the inner wall of the stack or chimney where it is collected in a trough and removed.

  • Patent number: 5620503
    Abstract: A humidifier system includes a spray apparatus in a housing which sprays a mist of water droplets onto a mist eliminator to intercept the mist of water droplets. The mist of droplets is captured in a liquid phase by the mist eliminator and is substantially completely converted into a vapor phase in the form of increased humidity in the air stream. A humidity sensor located downstream of the mist eliminator senses the humidity of the stream of air. A controller controls the quantity of water sprayed in response to the humidity sensed to maintain a predetermined humidity in the humidified stream of air. A second humidifier includes a heater which creates a region of intense heat to instantaneously evaporate water mist directed thereon in a stream of air. In a third embodiment, water and pressurized air are simultaneously injected into a region of intense heat.

  • Patent number: 5558687
    Abstract: A vaporizer (film evaporator) (13) for halide-free, silicon-containing liquid reactants used in producing preforms is provided. The vaporizer includes a plurality of packed-bed columns (22) surrounding a central tube (24). A mixture of liquid reactant, e.g., octamethyl-cyclotetrasiloxane, and gas, e.g., oxygen, is sprayed onto the top surfaces (54) of the columns (22) by a set of spray nozzles (32). The liquid reactant and the gas flow downward together through the columns and are heated by hot oil (28) which flows around the columns' walls (50). The liquid reactant evaporates into the gas until the dew point temperature is reached, at which point all of the liquid reactant will have been converted into vapor. The vapor/gas mixture exits the bottom surfaces 56 of columns (22), where its direction of flow changes from downward to upward. This change in flow direction separates higher molecular weight species (46) from the vapor/gas mixture.

  • Patent number: 5259931
    Abstract: A system for removing volatile constituents (e.g., hydrocarbons) from a liquid (e.g., water) containing the same by which there is a continuous countercurrent contact between the liquid and a forced air flow. Water collected in a reservoir is continuously pumped to the top of a stripping tower where it is dispersed downwardly over packing material. A blower forces air upwardly in the tower so as to remove the volatile constituents that exit the tower with the exit air. Since the water flow is continuous, multiple passes occur through the tower to enhance separation efficiency. Water from the base of the tower returns to the reservoir via overflow from a standpipe. A lower liquid level sensor in the reservoir initiates operation of the water pump to the tower, and an upper liquid level sensor initiates operations of another pump for pressure discharge from the base of the tower to an exterior site.
