  • Patent number: 8877016
    Abstract: Systems and methods for solar steam generation are described. The systems and methods include moving at least one frame mounted optical focusing lens to track the sun in two axes and disposing a water boiler at a focus of each optical focusing lens. Raw water is pumped through an inlet at a bottom of each boiler and solar energy is concentrated, using each optical focusing lens, on each boiler, heating the raw water in each boiler and evaporating steam from the raw water. The steam exits each boiler, via a steam outlet pipe. Remaining salts and solids in each boiler are ground by rotation of salt grinding-cleaning gears. These ground salts and solids are drained and/or pumped out of each boiler from an exit in the bottom of each boiler.

    Abstract: In a solvent recycling system, a distillation vessel having an upper distillation zone and a lower waste collection zone and means whereby solvent waste falls into said waste collection zone before solvent enters said distillation zone. The system preferably has a solvent vapour outlet and a heating means, whereby solvent enters the vessel from above through the solvent feed inlet and solvent waste falls into said waste collection zone before distillation is commenced, and a shut-off means or filling tube extending below the distillation zone associated with the inlet to prevent solvent vapours exiting the vessel through the inlet during distillation.

  • Publication number: 20090114521
    Abstract: A contaminated solvent recycling system comprises a distillation vessel having a distillation zone and a separate waste collection zone and heating means for heating contaminated solvent feed within the distillation zone vessel to distill off the solvent. By separating the distillation zone from the waste collection zone, the distillation zone can be made small enough to process small consecutive batches of contaminated solvent feed whilst the waste collection zone can be made large enough to accommodate waste accumulating from the distillation process for extended periods of time between waste removal operations.

  • Publication number: 20080152547
    Abstract: Turbulent mixing condensation devices, methods, and systems adapted to condense a working fluid on particles from a sample gas to enlarge the particles for subsequent detection are provided. The device includes a vapor generator adapted to produce a working-fluid saturated carrier gas and a condensation chamber. The working-fluid saturated carrier gas is mixed with a sample gas containing particles to be detected and is then introduced to the condensation chamber. The operating conditions are controlled to enhance the condensation of the working fluid on the particles. The particles are typically forwarded to a particle detection device to detect at least one characteristic, for example, the size, of the particles. The flow of carrier gas to the vapor generator may be regulated to vary the degree of saturation of the carrier gas with working fluid.

  • Patent number: 6797123
    Abstract: The present invention relates to a device for a distiller adapted to distil solvents for recovery of pure solvent from impure solvent, the solvent (2) being used for washing away residues of paint from spray guns. The distiller (1) includes an outer container (5) with a boiling chamber (8) which at the top has an opening (9) which can be tightly closed by a cover (10) and a flexible inner container (13) is provided in the boiling chamber (8), the flexible inner container (13) containing impure solvent to be distilled. A pipe means (20) is placed beside the flexible inner container (13) in order to allow solvent steam (7a), which is generated by boiling solvent in a lower space (19) beneath the flexible inner container (13), to pass from the lower space (19) into an upper space (16) having an outlet (17) and located above the flexible inner container (13) for preventing the solvent steam (7a) from lifting the flexible inner container (13) in the boiling chamber (8).

  • Patent number: 5308452
    Abstract: A waste photopolymer plate washout fluid solvent distillation apparatus includes a single enclosure enclosing a waste washout fluid container, a recovered solvent container, and a distillation unit in which waste washout is distilled by application of heat and vacuum pressure to the waste washout, and by supplying a metered supply of a surrogate solvent to the distilled waste washout as a desired solvent is distilled from the waste washout. The apparatus, by supplying the surrogate solvent to the waste washout as the desired solvent is distilled from the waste washout, enables a greater percentage of the desired solvent to be recovered from the waste washout than has been heretofore possible with prior art apparatus, and also enables the waste washout to be disposed of as a liquid.

  • Patent number: 4954223
    Abstract: A distillation apparatus including a pair of vertical lower vessels each open at its upper end, and a pair of elongate upper vessels each having an open lower end, slidably mounted in a respective one of the lower vessels. A heat exchanger is mounted in each of the upper vessels, with the upper end of one upper vessel being connected to the inlet of the heat exchanger in the other vessel, and vice versa. A reciprocating drive mechanism drives the two upper vessels up and down in opposite directions so as to simultaneously effect compression in the space above the liquid level in the downwardly moving vessel while expanding the space above the liquid in the other vessel, driving vapor from the downwardly moving vessel into the heat exchanger in the other vessel, where it condenses.

  • Patent number: 4536256
    Abstract: A solvent recovery apparatus including a housing having an open top tank therewithin for receiving a flexible bag. A bag holder member is removably mounted within the bag, and the holder member shapes the bag to hold it in an open condition for receiving dirty solvent directed into the tank. The holder member urges the upper edge of the bag against the inner surface of the tank so that substantially no solvent can migrate into the space between the bag and the tank. The tank has a space for receiving heating oil below a bottom thereof so that heat can be imparted to the contents of the bag to evaporate the solvent therewithin. Baffle structure in the oil causes the oil to circulate as the oil is heated by a resistance heater in the space. A quench coil below the bottom of the tank and above the oil receives a coolant for heating the liquid and solid contaminants left in the bag after evaporation of the solvent to minimize the delay in waiting for the contaminants to cool before removing the bag from the tank.

  • Patent number: 4457805
    Abstract: Apparatus and method for recovering clean solvent from a mixture of solvent and contaminants. The apparatus includes an open top tank mounted in a housing below a sink in which articles to be cleaned with solvent are placed. The sink has a tap through which solvent is directed so that the articles can be cleaned by hand in the sink itself. A disposable, plastic bag is receivable in the tank and the tank is closed by a cover. Contaminated solvent can flow from the sink, through the cover and into the bag in the tank. Contaminated solvent in the bag is heated by heating a liquid surrounding the side wall of the tank and below the bottom of the tank so that the solvent in the bag will vaporize. A tube leading out of the tank carries solvent vapor into a heat exchanger where the vapor is condensed to form clean, liquid solvent, and the liquid solvent is collected in a reservoir. A pump is coupled to the reservoir for pumping liquid solvent to the tap at the sink.

  • Patent number: 4414100
    Abstract: The present invention relates generally to fluidized catalytic cracking. More particularly, the present invention relates to a baffle arrangement that improves separation of gaseous hydrocarbon reaction products from catalyst within the reactor vessel of a fluidized catalytic cracker unit. The catalytic reactor vessel includes an outer generally cylindrical shell having a stripping zone arranged at the lower end of the vessel. An inlet riser conduit forming a primary reaction zone extends generally external to and generally parallel with the shell to a location near the top of the vessel. The upper end of the riser conduit then turns through, preferably through two right angle turns of each, so that the riser conduit enters the vessel either on a horizontal run into the side of the vessel and then turns downwardly, or on a downward run through the top of vessel, into the center of the vessel to form an outlet, discharging downwardly the mixture of hydrocarbon and catalyst.
