Abstract
Water is recovered and purified from exhaust gases of internal combustion engines which produce water vapor when a hydrocarbon fuel is burned. The present invention passes the engine exhaust through a particulate filter then a catalytic reactor to remove the impurities and then through a precooler and a condenser so as to extract the water therein. The water is then passed through a polishing column and recovered for use in the vehicle.
Claims2
Apparatus for recovering potable water from engine exhaust gases comprising, a particulate filter to which said engine exhaust gases are supplied, a catalytic reactor receiving the gases from said particulate filter, a condenser connected to receive the output gases of said catalytic reactor and cooling the output gases to a temperature such that the water condenses, and a water neutralizing means receiving the water which may contain some acid from said condenser and purifying and clarifying it to render it potable, wherein said engine has an exhaust pipe, a diverter valve with controller mounted in said engine exhaust pipe, a diverter pipe connected from said diverter valve to said particulate filter, a temperature sensor mounted in said engine exhaust pipe, and a control means receiving an input from said temperature sensor and connected to said controller of said diverter valve to actuate it to divert engine gases to said particulate filter when the temperature of said engine gases has reached a predetermined temperature.
