ABSTRACT:
In a vehicle having an engine which derives power from a reaction of NaK and water in the presence of air, NaK hydroxide is a reaction product in the form of particulates suspended in an exhaust gas consisting principally of nitrogen with some water vapor. In order to release the exhaust as a harmless gas to the atmosphere and to retain the NaK hydroxide in the vehicle for removal during a fuel stop and subsequent reduction back to NaK metal, several stages of separation of the particulates from the gas are provided. A first stage, preferably based upon impingement of the NaK hydroxide particulates on a molten NaK hydroxide surface, separates a substantial portion of the particulates. A final stage of separation comprises filtration wherein two filters are used alternately, one filter separating the water soluble NaK hydroxide particulates from the exhaust gas while the other filter is being flushed with water as a solvent to dissolve accumulated NaK hydroxide thereby regenerating the filter. The flushing water which contains the dissolved NaK hydroxide is returned to a reservoir which also provides the water for the reaction of NaK and water. The functions of storing a reactant for combustion and of storing a solvent for dissolving accumulated particulates are both provided by a single body of liquid to result in a more simple structure and in less weight than would be feasible if separate reservoirs were used for the reactant and for the solvent.
