Exhaust gas scrubber for internal combustion engines
An exhaust gas scrubber includes a closed tank partially filled with a pool of water and a core assembly within the tank. The assembly includes a vertical cylindrical mixing tube open at its opposite ends and extending above and below water level, an upwardly opening cylindrical deflector cup at the bottom of the tank with its opening concentrically spaced within the lower end of the mixing tube, and a downwardly opening cylindrical deflector hood concentrically receiving the upper end of the mixing tube. Exhaust gases are introduced into the tank through a gas inlet tube, which extends downwardly concentrically through the deflector hood and mixing tube to discharge the gases through its open lower end into the cup. The gases are deflected upwardly into an annular mixing and expansion chamber within the mixing tube through an annular gas orifice defined by an upper side wall of the cup and lower side wall of the inlet tube. As the gases enter the mixing chamber, they aspirate water droplets through an annular water orifice surrounding the gas orifice. The water droplets and gases intermix as they rise through the mixing chamber. The mixture further expands as it is expelled from its upper end, and is then deflected downwardly by the hood toward the pool of water. The water droplets return to the pool, while the lighter, expanded, cleansed and cooled gases are expelled from the tank through a gas exhaust tube. The scrubber as described can be used in either a make-up type water tank or a batch-type tank, both of which are disclosed and characterized by a tall narrow water pool surrounding the core.
