    摘要: A wave powered evaporation desalination system for removing fresh water from salt water by extraction of water vapor from a negative pressure container using wave motion for power. The wave powered evaporation desalination system includes a first vessel that accepts salt water. The salt water is forced from the first vessel through a atomizing spray nozzle into the top of a negative pressure second vessel. The negative pressure second vessel includes a number of trays that fill up with salt water films. Two pumps are attached to the top of the second vessel. One pump draws brine from the bottom of the second vessel for dispersion outside the system. The other pump draws off the water vapor from the second vessel into a hose and back to normal atmospheric pressure. The two pumps are powered by a float hinged to the second vessel.

    摘要: A vacuum low-temperature distilled pure water dispenser includes a water-supply tank communicating with a reaction chamber via a water supply line, a pure water storage tank communicably located above the reaction chamber, an actuating pump communicably located below the reaction chamber, and a refrigerating system having pipe lines extended between the reaction chamber and the pure water storage tank. When the actuating pump is actuated, a vacuum is produced in the reaction chamber to suck water in the water-supply tank into the reaction chamber, at where the sucked water is heated and vaporized by heat provided by a compressor of the refrigerating system, so that impurities, organic and inorganic matters, bacteria, and viruses in the water are separated therefrom through vacuum low-temperature distillation. When the actuating pump keeps pumping, the distilled water is sent from the reaction chamber into the pure water storage tank.

    摘要: Bubble columns fractionate with vapor-liquid mass transfer efficiencies approaching that of distillation towers when vapor velocities in excess of 50% of jet flood are used. If the vapor velocities are pushed above about 70% of jet flood then the distillation performance of a given column packing becomes similar for both liquid continuous operation (bubble column mode) and vapor continuous operation (ordinary distillation tower mode).

    摘要: A method and an apparatus for treating gasoline vapor by bringing gasoline vapor within a fuel tank into contact with a fluid gasoline and making the fluid gasoline absorb the gasoline vapor, in order to improve absorptivity of the gasoline vapor and to reduce the amount of the gasoline vapor introduced into a canister, thereby attaining a canister downsizing. The method and apparatus comprise a separation device of introducing the liquid gasoline within the fuel tank and separating it into a low boiling point component and a high boiling point component, and a gas-liquid contact device of bringing the gasoline vapor within the fuel tank into contact with an extractive gasoline composed of the high boiling point component separated by the separation device, whereby when contacting the gasoline vapor with the extractive gasoline, a part of the gasoline vapor is absorbed to the extractive gasoline, and a residual of the gasoline vapor not absorbed to the extractive gasoline is introduced into a canister.
