Wet gas modular venturi scrubbing apparatus

Claim 1

Multiple-throat venturi wet gas scrubbing apparatus adapted for in-line connection in a horizontal run of gas flow ducting comprising a venturi section rectangular in cross section and containing a plurality of modular multiple-throat standard venturi units arranged side-by-side and each having an inlet adapted to be connected to upstream ducting and a rectangular outlet; each said standard venturi unit comprising a plurality of generally vertical coplanar round rods of equal length and spaced apart in parallel relationship to define a plurality of parallel coplanar venturi throats, substantially identical horizontal rectangular top and bottom plates to which the respective ends of said rods are respectively permanently and rigidly secured, the plane defined by said rods being normal to the side edges of said rectangular plates, and spraying apparatus mounted in one of said plates; a demister section arranged downstream from said venturi section and containing at least one modular demister unit therein, said demister section being rectangular in cross section and having a rectangular inlet and a rectangular outlet; an inlet manifold unit initially separate from but in the assembled apparatus connecting said outlet of said venturi section with said inlet of said demister section; and means for connecting said outlet of said demister section with downstream ducting, said venturi section and said demister section being substantially coaxial and said apparatus being substantially coaxial with said ducting whereby a stream of gases flowing through said ducting flows horizontally substantially straight through said apparatus.
