Abstract: A desalination unit for production of potable water from sub-soil brine including in combination a trapezoidal basin, a condenser, a feed tank, a header, a heat exchanger, a flush valve, a sprinkling system, exhaust heat pipe and water collecting channel; where the exhaust heat pipe is connected to a heat source at one end and to the header at the another end, the header being coupled with the heat exchanger to provide the heat flow, and the heat exchanger being fitted at the inner portion of the trapezoidal basin to heat the sub-soil brine.

Abstract: A condenser includes: a top face of a tube plate on which acrylic acid may be condensed inside the condenser; a spray for spreading a polymerization inhibitor on the tube plate; a first polymerization inhibitor supply tube for supplying the polymerization inhibitor to the spray; and a supporter for supporting the spray at a predetermined position. The supporter supports the first polymerization inhibitor supply tube outside the condenser. The condenser allows a stable continuous operation for a long period of time by preventing polymerization of an easily polymerizable compound in the condenser into which a vapor of an easily polymerizable compound is supplied with a simple structure thereof.

Abstract: A system for the vacuum distillation of contaminated solvents incorporates a tank for holding a liquid contaminated solvent, a heating chamber surrounding the tank for heating the liquid contaminated solvent into an evaporated solvent, a drift elimination and fractionation device for separating contaminants out of the evaporated solvent, a heat exchanger circuit for cooling the evaporated solvent from the drift elimination and fractionation device, a pump circuit connected to receive the evaporated solvent from the drift elimination and fractionation device and to circulate the evaporated solvent through the heat exchanger circuit, and a control circuit connected to at least the heating element and the pump so as to control operation their based on parameters of a solvent selected to be processed. The control circuit includes a plurality of sensors for monitoring operating conditions of at least the tank, the heating chamber and the heat exchanger circuit.

Abstract: A distilled water supply device including a stand, a condensing unit mounted on the stand and separated by a partition wall into an upper chamber, which receives water from an external water source, and a bottom chamber, which condenses steam into distilled water, a heating unit detachably mounted inside the stand below the condensing unit and controlled to heat water from the upper chamber into steam, permitting steam to be guided into the bottom chamber for condensing, a vertical guide pipe for guiding water from the upper chamber to the heating unit, a vertical steam pipe for guiding steam from the heating unit to the bottom chamber for condensing.

Abstract: A water distillation apparatus includes a cylindrical housing with a first cover thereon, a pair of spaced apart funnel-shaped partitions, a second cover on the uppermost partition and a skirt extending downwardly from the periphery of the cover and the uppermost partition to a location above the bottom of the housing, the partitions and skirt dividing the interior of the housing into an inlet reservoir chamber for cold water above the first partition, a lower boiling chamber beneath the second partition and an inclined condensation passage between the partitions. Cold water is introduced through a pipe and solenoid valve into the bottom of the reservoir chamber for overflow through an opening in the second cover into the boiling chamber. A heater in the boiling chamber heats the water to produce steam which rises, passing into the condensation passage and flowing downwardly to a central drain for discharge into a distilled water reservoir beneath the housing.

Abstract: A water distiller includes a raw water chamber for storing raw water, a main vaporization tank coupled with the raw water chamber for vaporizing raw water, a condensation device coupled with the main vaporization tank for condensing steam from the main vaporization tank, and a distilled water chamber communicated with the condensing conduit unit for accepting and storing distilled water. An auxiliary vaporization tank is communicated with the main vaporization tank and is mounted on the top end portion of the main vaporization tank. Each of the main and auxiliary vaporization tanks has a generally conical top wall which has a lower end portion that is provided with an annular water collecting groove formed in the inner surface thereof. Each of the water collecting grooves has a bottom wall which has a discharge opening formed therethrough.

Abstract: A water desalination apparatus which is constructed of a main housing which includes a condensation chamber and a vapor chamber located above the condensation chamber. Brackish water is to be supplied into the vapor chamber with this brackish water to produce a vapor which is to be removed by a centrifugal compressor arrangement into the condensation chamber. The condensed brackish water from the vapor chamber is to flow through a mass of thin-walled tubes to be eventually discharged into the ambient. The exterior wall of these tubes is located within the condensation chamber and it is on the walls of these tubes that the distilled water vapor is to collect and condense and flow from the condensation chamber to a collection source.

Abstract: The apparatus includes a housing enclosing a boiler in the lower portion and a water-filled condenser in the upper portion with an insulated partition between them. The entry of boiler feed water is controlled by a float valve in the boiler, and steam from the boiler is conveyed through the partition and thus through a condenser coil substantially immersed in the water in the condenser.
