摘要： In one aspect, a cooling tower system is provided that includes an evaporative heat exchanger, a sensor configured to detect a parameter of evaporative liquid distributed onto the evaporative heat exchanger, and an evaporative liquid treatment system. The cooling tower system further includes a controller having a normal operating mode wherein the controller operates the evaporative liquid treatment system to treat the evaporative liquid upon a determination of inadequate evaporative liquid quality based at least in part on the parameter of the evaporative liquid. The controller has a failsafe operating mode wherein the controller changes operation of the cooling tower upon a determination that the operation of the evaporative liquid treatment system is unable to remedy the inadequate evaporative liquid quality.

摘要： An automated flush system for an evaporative cooling system may be employed in barns or other facilities that house animals to provide cooling and to reduce production loss. The evaporative cooling control system may include an automated flush system that has a controllable valve at a flush end of the cooling system. Based on a timer, the controllable valve is opened and water drains (e.g., pumped or gravity feed) out of the cooling pad enclosure. Fresh water is introduced at the “fill” end of the system, rinsing out the evaporative cooling pads. After a predetermined time, the valve at the flush end of the system is closed, and the fresh water refills the cooling pad enclosure.

摘要： A contact tray for use in a mass transfer or heat exchange column and having multiple baffles walls that cause the liquid flowing on an upper surface of a tray deck tray to change its direction of flow and narrow its flow path width and extend the length of the flow path when the liquid flows from an inlet area to an outlet on the tray deck. By narrowing the flow path, the volumetric flow rate of the liquid at any portion of the deck increases and reduces the opportunity for vapor entrainment of the liquid at low liquid flow rates. A downcomer extends downwardly from the outlet to receive liquid when it enters the outlet and then convey it downwardly to a discharge outlet located at a lower end of the downcomer. The downcomer includes an inclined or horizontal portion that causes the discharge outlet to be positioned beneath and in vertical alignment with the inlet area on the tray deck.

摘要： A fill support grid hanger for hanging a full support grid from a horizontal structural member that obviates the need for an intervening spacer bar. The hanger features a flange at the top, a plurality of blocks in the back to stabilize the hanger on the horizontal structural member, and three-dimensional features on the front side to receive and prevent lateral movement of two or more different types of fill support grids.

摘要： The present invention is directed to a cooling tower that has a cooling tower structure having fill material supported by the cooling tower structure and configured to receive heated process fluid and a motor mounted to the cooling tower structure. The motor has a casing and a rotatable shaft and is sealed to prevent fluids, moisture, foreign particles and contaminants from entering the casing. A fan is connected to the rotatable shaft of the motor. Rotation of the rotatable shaft rotates the fan thereby inducing an upward moving mass flow of cool air through the fill material. A basin is attached to the cooling tower structure for collecting cooled fluid. A fluid distribution system distributes the cooled fluid in the basin. The fluid distribution system has a pumping device to pump cooled fluid from the basin, fluid piping to receive the pumped cooled fluid and fluid spray devices fluidly connected to the fluid piping for spraying fluid on the casing of the motor so as to transfer heat of the casing to the fluid.

摘要： An example of a system for use in collecting fluid from a gas stream includes one or more collection panels and a frame for arranging the panel(s). Each of the collection panel(s) may comprise an emitter electrode assembly member, comprising one or more emitter electrodes, physically attached to an electrically insulated from a fluid collection member comprising one or more collection electrodes. The frame may be sized and shaped to be disposed near a gas outlet or a duct. An example of a method for collecting fluid from a gas stream includes providing the collection panel(s) disposed in a path of the gas stream; providing the gas stream; generating and maintaining a voltage at the one or more emitter electrodes of each of the collection panel(s); and collecting an amount of the fluid from the gas stream with the one or more collection panels.

摘要： Improved water management systems which deflect or collect evaporative liquid exiting counterflow heat exchangers and improve airflow distribution are provided. Such heat exchangers include open cooling towers, closed circuit cooling towers, and evaporative condensers. The improved water management systems eliminate water splash out and the noise associated with water splashing. Further, when the fan assemblies are located below the evaporative heat exchanger, the improved water management systems keep the fans dry and prevent freezing in subzero climates.

摘要： A heat exchanger may include a first container having a gas inlet, a liquid inlet, a gas outlet, and a liquid outlet. The gas inlet may flow a gas at a first temperature into the container while the liquid inlet introduces droplets of a liquid into the container at a second temperature. In the container, the liquid droplets may fall under the force of gravity while the gas flows through the container in a direction that is different from a direction of the spray of the liquid through the container. Accordingly, the liquid and the gas may come into direct contact within the first container and exchange heat. After the liquid and gas exchange heat, the liquid may leave the container through the liquid outlet and the gas may leave the container through the gas outlet.
