    摘要： A large and economical type of multi-stack vertical tube evaporator (MS-VTE) is disclosed having units of multiple stacks of vertical tube bundles or stages mounted in a single vessel, and having its liquid feed pumped to the uppermost VTE bundle stack or stage and having the feed then cascading downward through the lower bundle stacks in series flow, and wherein all the tube bundles are heated with the same waste steam of no or low $-value, e.g. with turbine reject steam in parallel flow under vacuum into the steam-sides of all tube bundles in the unit through a common steam conduit; and wherein the feed liquid is progressively evaporated from stage to stage or stack to stack and the vapors produced in the tubes of each bundle during the partial evaporation of the feed are separated between the stacks and condensed by parallel flow into one or more condensers. Applied to seawater desalination in a co-generation procedure with a coastal power plant, this evaporator produces about one pound of distilled water per pound of turbine reject steam used under vacuum and applied to single-effect mode in one evaporator unit or several units mounted in a single vessel with a condenser, to substantially reduce the cost of such useful distilled water. When applied in a similar cogeneration procedure but in a multi-effect series mode of several such units, or multiple units, the rate of distilled water production can be increased several-fold based on the amount of turbine reject steam applied.

    摘要： An improved upflow vertical tube evaporator is characterized by providing a distributor plate located within a certain critical distance or gap of the tube inlets in order to dampen cross flow between the tubes. The critical gap for providing stable operation is disclosed as lying between 0.01 and 0.2 of the average tube diameter. In the preferred embodiment, the distributor plate is capable of being translated relative to tube inlets so that the gap may be widened beyond the critical dimension during periods of stable flow in order to decrease the tube-side pressure drop and increase the heat transfer.

    摘要： A vertical tube evaporation process for the concentration of saline water and other liquids, including the addition of an anionic mono-molecular dispersant thereto which interacts with materials precipitated during concentration and inhibits the formation of scale or fouling depositions on evaporator surfaces, and wherein the additive is incorporated into the precipitated materials and improves their removal during the descaling or defouling of evaporator surfaces by rendering such precipitates redispersable in fresh water or in a non-saturated liquid used for descaling or defouling of evaporator surfaces.

    摘要： A process for the evaporation of an available warm or hot liquid under a vacuum by applying a pressure drop thereon initiating flash-down evaporation, and followed by further flash-down evaporation under an applied pressure gradient whereby the residual liquid is raised by the vapor produced to an elevation sufficient for subsequently discharging the residual liquid from vacuum without a pump; and by separating the vapor phase from the residual liquid phase before condensing the vapor produced into distilled liquid.

    摘要： A method and apparatus for forming an array of multiple parallel flow orifices, for example by holes drilled through a plate in a selected pattern and spacing and of selected sizes or flow diameters, and whereby these orifices are used to provide an approximately equal and adequate distribution of liquid flowing through them as parallel streams of liquid and into an evaporation zone or a parallel array of evaporation channels, and wherein the orifices can be adjusted in flow diameter to control the flowrate of liquid in generally parallel streams with an array of orifice adjusting apparatus, for example an adjacent sliding orifice plate which provides for orifice flow rate adjustment with orifices through this second plate corresponding in position to those of the first orifice plate, and the use of such dual orifice plates for supporting a pool of liquid there-above and for controlling the flowrate of liquid through the first array of orifices by reducing or enlarging their orifice flow diameters to control the level of the liquid in the pool or the pressure of this pool on or at the orifices and controlling the effect-to-effect pressure causing flashdown, and to improve the evaporation process or the degree of evaporation in an adjacent flash evaporation zone or in a bundle of adjacent evaporator tubes, and when applied to a multi-effect series of several such vertical tube evaporators.
