SCR denitration catalyst detection lab scale rectifier for device and device thereof

The utility model provides a SCR denitration catalyst detection lab scale rectifier for device and device thereof, rectifier 33 is both ends open -ended cavity sleeve pipe shape, and can the detachable cover locates the flue gas entry end of the sample box 31 that loads the catalyst, the cross section of an arbitrary department of the inner space that the cavity sleeve pipe encloses is the same with sample box cross section, and the inner space that encloses of cavity sleeve pipe and sample box inner space form continuous unobstructed passageway, the inner space is controlled baffle quantity and is set up the position along vertically setting up at least one baffle 331 for the baffle can roughly cover the catalyst surface of sample box opening one side, and the baffle and the cross section of the residual space that the inner space formed respectively and the cross section in the space that forms between the catalyst corresponding.
