  • Patent number: 8668187
    Abstract: The integrated aeration system utilizes a water pump for aeration. Ambient air/gas is entrained by a circulating water jet induced by the pump. The circulating water jet enters a sealed tank. The entrained gas is broken into bubbles after the impingement between the jet and a receiving pool occurs, aerating the receiving pool by water jet spray. The entrained gas/air builds up headspace pressure above the water pool, the headspace pressure being measured by a pressure gauge. The trapped air above the water pool is released when the headspace pressure increases to reach a desired value to aerate a separate tank/container as a diffused aeration or any other aeration process.

  • Patent number: 7267328
    Abstract: The subject of this invention is a submerged airlift pump using multiple concentric pipes with diameters that increase as they near the water surface. Water initially accelerated into the lowest pipe section is progressively decelerated in subsequent pipe sections, increasing the residence time of the bubbles and hence the total driving force of the pump. Pipe proportions are optimized with gas flows to maximize total pump discharge at extremely low pumping-heads, resulting in ultra-high pumping efficiencies. This device can be used to promote circulation of large volumes of deep pond water, deficient in oxygen, to the surface, creating an increase in the exchange of gases between the atmosphere and water with minimal energy requirements.

    Abstract: A gas humidifier provides a continuous flow of gas through two stages of bubbling with an intermediate heating stage. Gas is introduced into an enclosure containing a quantity of bulk water by pumping the gas into a gas entry pipe or tube. The gas exits the gas entry pipe to bubble up through a bubbling evaporator. At the water surface of the bubbling evaporator, a heating element heats the gas-vapor mixture. The heated gas-vapor mixture then bubbles up through the bulk water, and the temperature of the bulk water determines the thermal cycles of the heating element. The gas-vapor mixture bubbles up through the bulk water, reaching saturation at the dew point. The saturated gas is then directed from the humidifier for use.

  • Patent number: 6315273
    Abstract: A gas and liquid contacting apparatus, illuminated, with circulation, and a method, are disclosed. To remove a trace component from a mixture of gases, for example to remove carbon dioxide from air, the inefficiency of attempting to dissolve all of the gas mixture followed by desorption of the non target components is overcome by injecting small bubbles (5) into a liquid filled chamber (1) which is inclined at an angle and has an abrupt change in cross section (2) & (3). The target component diffuses out of the small bubbles. The small bubbles, substantially relieved of the target component, are collected in a gas trap (4) created by the inclination and dimension change of the chamber. Large bubbles (8) escaping from the gas trap via an upper riser (9) to a reservoir (10) assist with the circulation of the contents of the system. A return tube (11) connecting the reservoir to the bottom end of the chamber completes the circuit.

  • Patent number: 5968352
    Abstract: Intimate contact of water with a treatment gas is achieved by mixing the gas and water co-currently in a conduit containing static mixers, and directing the conduit into a gas contact apparatus that contains coaxial inner and outer tanks, the inner tank being open within, and shorter than, the outer tank, leaving a head space above the top of the inner tank. The conduit discharges the gas-water mixture at the base of the interior of the inner tank, permitting the water to flow upward through the annular space between the inner tank and the conduit, then over the weir formed by the open upper end of the inner tank and downward through the annular space between the inner and outer tanks. Gas is separated from the water at the head space, and treated degasified water leaves the apparatus at the base of the outer tank.

  • Patent number: 5944997
    Abstract: The outer surfaces of hollow fiber membranes in a skein, or a bank or cassette of stacked skeins, are kept essentially free of solids by maintaining a substantially uniform flow of a stream of coarse bubbles through each of plural orifices in an aerator disposed beneath the fibers. Aerators for skeins used in microfiltration of wastewater in a tank are periodically flushed by injecting flushing air into permeate returned to the tank over a short period. The air is injected into returning permeate for less than 1 minute, preferably less than 20 sec so as to produce discrete masses of water which are flowed laterally through the body of the aerator, cleaning its walls and maintaining the orifices essentially free from plugging.

  • Patent number: 5560756
    Abstract: A chimney smoke scrubber for use with stoves and fireplaces includes a chimney cap enclosure secured atop the chimney or flue pipe of the combustion unit. The combustion gases from the enclosure are deliver through a duct to a smoke scrubber assembly. The scrubber assembly includes a tank holding a charge of water, with flow space above the water surface for smoke to pass. A stack extends upwardly from the flow space of the tank to release the flue gas to atmosphere. The upper end of the stack includes outlet holes or a screen, and a stack cap having an interior deflector. A nozzle is disposed within the stack and directed to emit a controlled spray upwardly to impinge on the deflector cap. The spray and the deflected water form a curtain of water that cascades downwardly past the outlet holes or screen, so that the smoke and gases must pass through the water cascade as they are discharged.

  • Patent number: 5433925
    Abstract: A process and apparatus for removing SO.sub.2 from low-volume gas streams containing high concentrations of SO.sub.2 includes a tank scrubber containing an aqueous SO.sub.2 absorbent and an impeller. The tank scrubber has an unpartitioned vessel. The impeller includes a vertical rotating shaft having an upper and lower impeller. The lower impeller serves to agitate the SO.sub.2 absorbent. The upper impeller includes a shroud thereby directing the absorbent and gas outwardly toward the wall of the scrubber. The gas is injected into the absorbent at a point below the shrouded impeller. The shroud prevents gas bypass and thereby promotes gas-liquid mixing and, consequently, markedly improves SO.sub.2 removal efficiency.

  • Patent number: 4927596
    Abstract: A self-actuating passive pressure relief device for nuclear reactor containments is described. The pressure relief device passively releases gases from within a reactor containment when the containment pressure exceeds a designated threshold pressure. The pressure relief device automatically reseals itself when the containment pressure drops below the threshold pressure. Any containment gases that are vented by the pressure relief device from the containment are scrubbed and cleansed before they are released into the atmosphere. To accomplish this, a sealed fluid chamber is placed in direct communication with the reactor containment for holding a liquid material such as water. A standpipe having its lower end extend into the sealed container and has an opening below the normal operating liquid level within the chamber.

    Abstract: The device for the wet cleaning of flue gas is mounted on a chimney (12). It consists of a basin (18) surrounding the flue gas pass in a ring shape with a cleaning fluid (20). A hood covering the flue gas pass (22) guides the flue gas through the cleaning fluid (20). A turbulence device (24) is foreseen on the edge of the hood (22), this ensuring intensive contact of the flue gas with the cleaning fluid. The turbulence device may consist of numerous convoluted sheets maintained in concentric, vertical arrangement which are located in a hollow space closed at the top and form concentric, vertical stream channels. The flue gas streams into these channels which are moistened and filled with bubbles alternately upwards and downwards.
