  • Publication number: 20100086827
    Abstract: A gas-liquid separation device is used in a fuel cell system including fuel cells. The gas-liquid separation device includes: a separator configured to separate a fuel gas after an electrochemical reaction performed in the fuel cells from liquid water flowing with the fuel gas; and a reservoir configured to allow accumulation of the liquid water discharged from the fuel cells. The gas-liquid separation device also has a fluid outflow path arranged to connect with a connection object member and have a fluid outlet formed to be open in a vertical direction. The fluid outflow path is configured to flow out a fluid from inside of the gas-liquid separation device to the connection object member via the fluid outlet. The fluid outlet is provided to differ in position in a direction perpendicular to a vertical direction from the separator and the reservoir.

  • Publication number: 20090238938
    Abstract: A system and method for carbonizing a liquid, such as tap water with CO2, are disclosed. The liquid is carbonized inside a pump housing, thereby obviating the need for a separate high-pressure carbonator tank and a separate feed pump. The pump housing has an inlet for receiving in combination the liquid and CO2 at a first pressure, and an outlet for transporting the liquid carbonized with CO2 from the pump housing into an outlet line at a second pressure higher than the first pressure. A constriction is disposed in the outlet line for producing said higher pressure with the pump. The system and method can be employed in closed-loop carbonizing systems in the beverage industry.

  • Patent number: 7527247
    Abstract: An apparatus for exposing air to an aromatic substance (26) at a uniform level of aroma for a certain period of time without using gas, fire, or applied electric heat source. The invention has an aromatic solution tank (31) on which sits a lid (30) under which is mounted a motor (32) engaged by a micro-switch (34). Disposed on the motor shaft is an impeller (36) generating a guide air flow through a chamber of free space in the tank via an intake housing (35), inlet (21a) and outlet (25b) holes in the lid, and attached a draw tube (37). Rotation (20) of the draw tube delivers a 360 degree sheet of aromatic solution (24) across flowing air (22), air which is then discharged (25a) to environment. Consequently, air flowing through the swirl of aromatic solution is exposed at a uniform level for a certain period of time.

  • Patent number: 7422684
    Abstract: A method and apparatus of sanitizing drinking water to be dispensed from a water dispenser having a reservoir includes the steps of providing the ozone gas generator that generates an ozone gas stream, transmitting the ozone gas stream from the generator to the water dispenser reservoir, mechanically breaking up the ozone gas stream inside the reservoir to produce ozone gas bubbles, and using the ozone gas bubbles to disinfect water in the reservoir. The ozone gas stream can be mechanically broken up using a pump such as, for example, an impeller type pump.

  • Patent number: 7377492
    Abstract: A system for concentrating gas, using the concentrated gas to pump liquid, and recycling the gas and liquid is disclosed. The system comprises a body of liquid, a down pipe in fluid communication with the body of liquid, a gas injection apparatus for introducing gas into the liquid that passes through the down pipe, a separator for separating compressed gas from the liquid, and a gas-liquid recycle loop. The down pipe and the gas injection apparatus are structured and arranged to compress the gas. The gas-liquid recycle loop comprises a compressed gas storage vessel containing the separated gas, a reservoir containing liquid separated from the compressed gas, and a gas-liquid pump. The gas-liquid pump has a gas inlet in communication with the gas storage vessel, and a fluid inlet in communication with the reservoir. The gas-liquid pump is structured and arranged for pumping the liquid back to the body of liquid and delivering the gas to the gas injection apparatus.

  • Patent number: 7243909
    Abstract: The present invention relates to a cooling apparatus and method wherein a supply sump and turbine are below grade. Water cooled from an above grade cooling tower fan and fill flows into the supply sump and is pumped through below grade pipes into a facility. Heat rejected water from the facility then flows through below grade pipes into a below grade collector sump. A collector sump pump pumps the heat rejected water above grade into a nozzle and back into the fill to be cooled. The present invention is constructed such that water is not idle in any above grade component. Accordingly, the risk of water freezing within the above grade components is drastically reduced. Moreover, the heat rejection water can by-pass all above grade components and travel directly into the supply sump in the event of reduced load from the facility.

  • Patent number: 7210671
    Abstract: The invention provides an improved natural draft cooling tower (10) having improved cooling capability and reduced liquid losses of evaporation and blow-out. To this end, the distribution of hot liquid to the packing assembly within the tower is increased around the perimeter zone of the packing assembly and reduced within the remaining packing assembly of the tower (24). A plurality of air injector fans (30) spaced circumferentially in the air inlet (20) between the shell (12) support columns (14), together with reduced air resistance through reduced hot liquid distribution to tower interior, produce increased air rates (32) and (34) resulting in improved cooling capability and reduced evaporation loss. With improved cooling, further reduction in evaporation, if required, can be achieved with a hot liquid by-pass (52).

  • Patent number: 7179375
    Abstract: A method of treatment of water in an aquatic environment. Water is first pumped from a reservoir to a first mixing station. An inert gas is introduced into the pumped water at the first mixing station to provide inert gas saturated water, which inert gas saturated water will displace undesired gasses in the water in the reservoir. The inert gas saturated water is then pumped to a sparging column such that the inert gas and undesired gasses will be released from the inert gas saturated water to provide depleted water. The depleted water is then pumped to a second mixing station, wherein oxygen is introduced into the depleted water to provide oxygen enriched water. The oxygen enriched water is then returned to reservoir.
