Claim:
1. An apparatus for removing contaminants from emissions comprising: a housing shaped as a reverse venturi, said housing including an entry portion for receiving the emissions at a pre-determined entry flow rate, an exit portion for expelling the emissions at a pre-determined exit flow rate, and an enlarged portion disposed between said entry portion and said exit portion of said housing for trapping the contaminants in the emissions; said entry portion, said exit portion, and said enlarged portion of said housing being arranged in fluid communication with each other; said entry portion of said housing having an entry portion cross-sectional area; said exit portion of said housing having an exit portion cross-sectional area; said enlarged portion of said housing having an enlarged portion cross-sectional area that is larger than said entry portion cross-sectional area and that is larger than said exit portion cross-sectional area; a mass of reactive material disposed within said enlarged portion of said housing; said mass of reactive material having a reactive outer surface disposed in contact with the emissions; and said mass of reactive material containing an amalgam forming metal at said reactive outer surface that chemically binds at least some of the contaminants in the emissions that are passing through said enlarged portion of said housing to said reactive outer surface of said mass of reactive material, wherein said mass of reactive material forms at least one obstruction element disposed within said enlarged portion of said housing that creates a tortuous flow path for the emissions passing through said enlarged portion of said housing.
