摘要： Aqueous saline solutions are converted in part to potable water by passing a compressed aqueous saline solution through one or more beds of contained pellets of higher temperature to heat the aqueous solution to a flash vaporization temperature, then passing the solution to one or more flash vaporization zones. Vaporized potable water from each vaporization zone is separately passed to contained bed of pellets where water is condensed and pellets heated. Simultaneously, a bed of pelletized solids is heated to supplant the highest temperature bed in the system used for heating. By selective switching of beds, the system is kept in continuous operation with a heated bed of pellets replacing the highest temperature bed previously used to heat the aqueous saline solution. The bed used for water condensation is transferred to the heating cycle for subsequent introduction to the system.

摘要： A method is provided for the transfer of heat from a source of thermal energy to at least one thermal user or heat consuming apparatus wherein waste water, such as from an industrial process, is used as the heat transfer medium and wherein a portion of the waste water flow is evaporated in an indirect heat exchanger under pressure to yield a mixture of steam and heated liquid waste water. The steam is supplied to an indirect heat exchanger for supplying heat to the heat consuming apparatus and the heated waste water is subsequently vaporized in a plurality of stages by reducing the pressure on the waste water in each stage and by using the steam formed by the vaporization in each stage to supply part of the heat of vaporization for the waste water in the subsequent stage. When the heat requirement of the heat consuming apparatus is reduced, the heat exchanger supplying heat to the heat consuming apparatus may be valved out of the system or the steam flow thereto may be reduced. With an increased waste water yield from the particular process, a portion of the pressurized steam formed therefrom in the high pressure evaporator which flows to the heat exchanger for the heat consuming apparatus may be diverted to another part of the system.

摘要： Minerals are recovered from warm geothermal brines by installing a brine eductor device such as a venturi at the end of a thermally insulated drill casing. The geothermal brine is recovered by flowing a warm, low saline carrier solution at high flow rate through the device to pick up a selected flow of brine. On entering the device the geothermal brine is diluted in an amount sufficient to preclude precipitation and scaling as the mixture flows to the surface. The flow velocity is adequate to entrain any non-dissolved solids without settlement. Thermal losses to the surrounding strata are minimized by the thermal insulation surrounding the casing. The mineral values are recovered from the mixture by flashing, evaporation, and filtration. Clarified solution, filter liquor and make-up water as necessary are combined to form the low salinity carrier solution which is heated in heat exchangers before recycling to the eductor device. The heat exchange fluid may be heated by solar concentrators assisted by fossil fuel, geothermal and/or solar buffer stages.

摘要： An apparatus and method for removing contaminants from water having solid contaminants dissolved therein. Contaminated water flows across a grid and into a storage tank. The grid utilizes solar energy to heat that water to a predetermined temperature. A heat transfer structure which is dome-shaped and receives water from the storage tank and a preheater means utilizing solar energy heats the water to a further predetermined temperature. An evaporator means receives the heated water and exposes it to a vacuum condition so that the temperature of the water is above the saturation temperature. The water is thus vaporized, and solid contaminants dissolved therein are separated therefrom. The solids are deposited on a plurality of moving belts and are then moved into a solids removal system. The solids removal system comprises a plurality of trap door pairs upon which the solids are deposited and which are sequentially opened so that the vacuum conditions existing in the evaporator are not disturbed. Vapor transferring means removes the water vapor from the evaporator and transfers it to the heat transfer structure wherein it is condensed to form distillate which is free of solid contaminants. Distillate removal means then removes the distillate from the heat transfer structure to collection or usage means.

摘要： Liquid purifying apparatus in which an infeed chamber, an evaporator chamber and a condenser chamber are arranged in that order along a flow path. A first inflatable bag is interposed across the flow path between the infeed chamber and the evaporator chamber, and a second inflatable bag is interposed across the flow path between the evaporator chamber and the condenser chamber. These bags are respectively located substantially entirely in the evaporator and condenser chambers, and the bags each comprise a flexible layer of highly absorbent fibrous material including a plurality of plies. The liquid to be purified is introduced into the infeed chamber, and it flows into the evaporator chamber to a level such that a portion of the first bag is immersed in the liquid. The liquid spreads by immersion and capillary action over substantially all of the fibers in the first bag to form thin liquid films along the individual fibers. Upon the introduction of air into the infeed chamber and through the first bag to the evaporator chamber, the bag inflates, and the air passes over the individual fibers to vaporize the liquid films. The vapor proceeds through the secong bag into the condenser chamber to inflate the second bag and form the condensate. Previously purified liquid is used to form thin films on the fibers of the second bag to provide an additional evaporation effect and thereby reduce the temperature within the condenser chamber. In some embodiments this cooling action is augmented by directing the residual vapor through a series of perforations in the wall of the condenser chamber in a manner such that a further evaporation effect takes place as the vapor is discharged.
