The utility model discloses the during operation loads and has honeycomb catalyst or plate catalyst between loading grid and the water conservancy diversion grid, and its whole setting is in various combustion apparatus's exhaust passage for the desulfurization or take off the round pin, when the flue gas passed the catalyst, the water conservancy diversion grid played the reposition of redundant personnel guide effect, guided the catalyst layer with the flue gas, can reduce the flue gas velocity of flow, protection catalyst body, and simultaneously, the ridge arch can slow down the striking of the solid particle in the flue gas, and reducing wear makes the device work more reliable. The device is adaptable to various flue gas conditions, has better structural stability, is suitable for large flue gas flow velocity, and carries out desulfurization and denitration on the flue gas in the industry with higher soot.

And in order to facilitate connection and fixation, the peripheries of the flow guide grating and the loading grating are provided with frames, and the frames are connected with the side plates through bolts.

In order to further reduce abrasion, the upper surface of the guide grid plate is provided with an abrasion-resistant layer.

In order to facilitate hoisting and transportation, the side plate is provided with a lifting lug.

The utility model discloses a further improvement lies in, water conservancy diversion grid and grid plate one-to-one, direction grid plate correspond and set up directly over the grid plate. This scheme can load the catalyst between the space of the grid board of mutual isolation, and the water conservancy diversion grid shelters from the clearance between catalyst and the grid board, reduces the flue gas and follows the possibility of short circuit in the clearance for flue gas desulfurization, denitration effect are better.

Furthermore, the flow guide grid and the grid plate are welded and connected into a whole. Or the diversion grating and the grid plate are in a split structure, and a gap is reserved between the diversion grating and the grid plate.

Further, a loading net for placing the catalyst module is arranged on the upper side of the loading grid. For strong stability, the corner of the loading grid is provided with a reinforcing plate.
