    Abstract: An enclosed tank with a liquid inlet, a liquid outlet, a gas inlet, and a gas outlet. A liquid is forced to flow turbulently through the tank. Simultaneously a scrubbing gas is pumped through the tank. Turbulence induced in the liquid encourages gasses dissolved in the liquid to transfer to the scrubbing gas and thence to exit the gas outlet. Liquid pressure is provided externally to the invention, such as by a water utility or house water pump. The liquid inlet has a nozzle that injects the liquid against baffles in the tank to create turbulence. The liquid level in the tank is stabilized by controlling the scrubbing gas pressure. A lower layer of liquid and an upper layer of scrubbing gas are maintained in the tank as they flow through the tank together. Various liquid level stabilizing means are shown as examples. An electronic feedback system optionally controls the scrubbing gas flow rate according to the contamination level of the liquid.

    Abstract: Apparatus and methods for separating fluids of differing specific gravities are discussed. More specifically, apparatus and methods for separating a high volume flow mixture of air and water into an essentially dry air component and a pure water component are discussed. The separator is high volume and is structured around three physical elements which are defined as an input, a water chamber and an air separator chamber. A composite flow enters the input where most of the heavier water component separates, under the force of gravity, and flows into the water chamber. The remaining fluid, which is air and water in the form of vapor, mist, or droplets, is drawn into the air separator chamber using a vacuum pump, and subsequently flows through a condensate sub chamber which physically is an element of the air separator chamber. Any moisture in this flow is condensed within, and drained from, the condensate chamber such that dry air is discharged from the air separator chamber.

    Abstract: A tank for removing unabsorbed gas from a mixture of unabsorbed gas and liquid. The tank has an inlet pipe that carries an unabsorbed gas and liquid mixture into the tank. A deflector is located at the exit of the inlet pipe so that when the unabsorbed gas and liquid mixture strikes the deflector there is a rapid reduction of flow velocity of the mixture and a directional change of flow of the mixture. A separation chamber, in the form of a cylinder, extends at one end into a gas pocket and at the other end into the mixture at the bottom of the tank past the deflector so that once the mixture hits the deflector the less dense unabsorbed gas is directed generally upwards. When it reaches the top of the separation chamber the unabsorbed gas passes into the gas pocket. A liquid retention chamber is defined by the wall of a second cylinder and an outlet pipe.

    Abstract: This invention consists of apparatus and methods for separating fluids of differing specific gravities, and more particularly apparatus and methods for separating a high volume flow of fluid comprising a mixture of air and water into an essentially dry air component and a pure water component. The separator is high volume and is structured around three physical elements which are defined as an input, a water chamber and an air separator chamber. A composite flow enters the input where most of and flows into the water chamber. The remaining fluid, which is air and water in the form of vapors mist, or droplets, is drawn into the air separator chamber using a vacuum pump, and subsequently flows through a condensate sub chamber which physically is an element of the air separator chamber. Any moisture in this flow is condensed within, and drained from, the condensate chamber such that dry air is discharged from the air separator chamber.

  • Patent number: 5601635
    Abstract: A method and apparatus for deaerating a liquid in a substantially closed liquid circulation system, wherein an amount of liquid is withdrawn from the circulation system and is introduced into a closed reservoir via a valve which is alternately open and closed, wherein by a pump which is operative in the open as well as the closed positions of the valve an underpressure can be created in the reservoir for the purpose of deaerating the liquid, and the liquid can be sucked from the reservoir and added to the circulation system again, separated air being discharged via a vent unit to the environment. For the valve adapted to be opened and closed alternately, preferably a throttling valve is used.

  • Patent number: 5490874
    Abstract: A de-aerator apparatus for removing gas from fluid flowing through a pipe includes a housing having a chamber, an inlet connected to an inlet pipe for allowing the passage of fluid into the chamber, an outlet connected to an outlet pipe for discharging fluid from the chamber, and a vent for venting gas from the top of the chamber. The arrangement is such that as fluid flows into the chamber through the inlet and out of the chamber through the outlet, relatively large gas pockets present in the fluid in the chamber rise to the surface of the fluid and exit the chamber through the vent. A device disposed within the chamber has bristles facing the flow of fluid into the chamber through the inlet. The bristles vibrate for merging micro gas pockets present in the fluid with one another to produce large gas pockets which rise to the surface of the fluid within the chamber and exit the chamber through the vent.

  • Patent number: 5487765
    Abstract: Apparatus for purging non-condensable gases from a condenser containing vaporized, condensable working fluid, includes an enclosed chamber located above the condenser, a movable diaphragm in the chamber for dividing the latter into upper and lower portions, two flow control valves serially connected together and located between the condenser and the lower portion of the chamber, and a venting valve connected to the lower portion. Each of the valves are selectively operable and have an open and a closed state. A mechanism is provided for moving the diaphragm for changing the volume of the lower portion; and a mechanism is provided for synchronizing the states of the valves with changes in the volume of the lower portion.

  • Patent number: 5341832
    Abstract: The present invention concerns a device sequence for burning waste oil and includes a circulating system having a pump for circulating the oil therein and a heater for heating the oil to a suitable combustion temperature during this circulation. A combustion oil system is included for diverting a portion of the circulating oil to an atomizing gun for combination therein with a source of atomizing air. The air and oil mixture is injected through an injection orifice into a suitable combustion chamber for ignition and burning therein. A linear actuator is included having a rod with a needle end that is operated by the actuator in a linear manner along the central axis of the atomizing gun for extending through the injection orifice for providing mechanical cleaning thereof and for regulating oil flow there through.

  • Patent number: 5308386
    Abstract: The present invention is directed towards an air relief valve for a pressure vessel which automatically releases air from the system during filling with liquid, and which automatically seals when the liquid in the system reaches a predetermined level to prevent the liquid from leaving the system. The air relief valve of the present invention includes a valve body which provides communication between the pressure vessel and a series of output ports. These output ports are provide with a pressure indicator, a manual pressure release valve, and an automatic air relief valve. The manual pressure release valve is operable by the user to introduce air into the system, which is necessary during draining. The automatic air relief valve is generally a one-way valve, allowing air to exit but not enter the system.
