HYDROGEN-POWERED DESALINATION PLANT

摘要

The hydrogen-powered desalination plant is a multi-stage flash desalination system using hydrogen fuel to power the top brine heater of the plant. The hydrogen-powered desalination plant includes a plurality of flash distillation stages, which each include a flash chamber and a condenser. The top brine heater in the hydrogen-powered desalination plant is powered by the carbon-free combustion of hydrogen gas with oxygen gas. The combustion of the hydrogen gas with the oxygen gas creates a flame, which is used directly to generate steam from atomized seawater, any seawater not converted to steam being collected as preheated brine and passed to the multi-stage flash desalination system for successive stages of flash distillation. Preferably, the flame is generated as a vortex.

主权项

1. A hydrogen-powered desalination plant, comprising:
a plurality of flash distillation stages, each of the flash distillation stages including a flash chamber and a feed heater, the feed heater having at least one conduit having an inlet and an outlet, the at least one conduit passing through the plurality of flash chambers; a pump connected to the condenser for feeding brine under pressure through the at least one conduit; a top brine heater having:
a housing having a combustion chamber and a pool to collect the brine disposed below the combustion chamber;an inlet connected to the outlet of the feed heater of a first one of the flash distillation stages, the inlet extending into the combustion chamber;a plurality of sprinkler nozzles disposed in the combustion chamber at the top brine heater inlet for atomizing the brine entering the combustion chamber;a source of hydrogen gas, a source of oxygen gas, and a metered conduit system extending between the gas sources and the combustion chamber for introducing metered amounts of hydrogen and oxygen into the combustion chamber;an igniter selectively introducing a flame into the combustion chamber to ignite the hydrogen and oxygen to convert the atomized brine into steam and preheated brine, the preheated brine collecting in the brine heater; a steam conduit extending from the top brine heater through the flash chambers for heating brine flowing through the feed heaters in the flash chambers; a brine conduit extending from the brine heater through the flash chambers for conveying the preheated brine through successive flash chambers for successive stages of evaporation and condensation, thereby producing desalinated water; a desalination exit port extending from the flash chambers for removing the desalinated water from the flash chambers; and a brine exit port extending from the flash chambers for removing concentrated brine from the flash chambers.
