Document Type and Number:

WIPO Patent Application WO/2002/011865

Kind Code:

A1

Abstract:

A waste gas treating device comprising an inlet duct having an inflow of waste gas, a catalyst duct having a waste gas cleaning catalyst disposed therein, these ducts being connected at a bend, and a flow regulating lattice having a height (A) arranged in the direction of cross-section of the catalyst duct inlet port, wherein the device includes a flow regulating lattice outer frame having a height (B) so arranged as to take the same position as the flow regulator lattice upper surface in order to support the flow regulating lattice, and a flow regulating lattice support beam installed parallel with the flow regulating lattice in order to support the flow regulating lattice outer frame, the device having a flow regulator which satisfies the formula A < B, wherein drift current on the catalyst layer is prevented.
