Electrodialytic demineralizing unit for humidification purposes

Abstract

Abstract The unit includes at least one electrodialytic ''''half-cell'''' in which a single cation-selective membrane separates the cell into a product flow chamber and a purge flow chamber and in which an anode is disposed in the product flow chamber and a cathode is disposed in purge flow chamber. Tap water is demineralized when a electric potential is established between the electrodes which pulls the cation constituents of lime, principally calcium, magnesium and manganese, out of the product flow chamber through the cation-selective membrane and into the purge flow chamber. In the preferred embodiment, the demineralized product is delivered to a nozzle in the air plenum of a furnace for atomization and humidification of hot air passing therethrough.
