Pollution control apparatus

A pollution control apparatus for a motor vehicle having an engine discharging exhaust gases into a muffler and out through a tail pipe, said apparatus comprising

• means to spray water into said exhaust gases into produce a mist of water droplets containing dissolved and entrained pollutants in said exhaust gases and connected to said muffler,
• means to separate said water droplets from said exhaust gas mist and pass cleaned exhaust gases from said muffler and out through said tail pipe,
• said water droplet separating means comprising a housing having a wall with an opening therein dividing the housing into plurality of chambers,
• means in each of said chambers for separating said water droplets from said mist,
• means to separate entrained gases from said separated water droplets and pass on a stream of water,
• said separating means comprising a bladed rotor in each chamber positioned to be impinged and rotated by flow of said mist to coalesce and separate water droplets by centrifugal action,
• baffles in said chambers to be impinged by said droplets to flow to the bottom of said chambers,
• an outlet from said housing connected to discharge cleaned gases to said tail pipe, and
• outlets in the bottom of said chambers to discharge collected water therefrom,
• means to separate particulate matter from said stream of water, and
• means to circulate said stream of water, free of particulate matter, to said spray means.
