Description of reference numerals: 1. housing support body, 2. catalyst veneer, 2-1. feeler.
The specific embodiment
The utility model aims to provide a kind of board-like denitrating catalyst module, with solve traditional board-like catalyst module because of with the lower problem of the little catalytic efficiency that causes of flue gas contact area.Below in conjunction with accompanying drawing the utility model is used further detailed explanation.
Fig. 1 is the perspective view of a kind of board-like denitrating catalyst module embodiment of the utility model.As shown in Figure 1, the board-like denitrating catalyst module of the utility model comprises housing support body 1, in said housing support body 1, is provided with at least one catalyst veneer 2, is laid with active component in said catalyst veneer both sides; Between said at least one catalyst veneer 2 and said housing support body 1 inwall, be formed with exhaust gases passes.
The board-like denitrating catalyst module of the utility model; Be provided with at least one catalyst veneer outside in the frame body; Between said at least one catalyst veneer and said housing support body inwall, be formed with exhaust gases passes, increased the contact area with flue gas, improved catalytic efficiency.
Wherein, both sides are laid with the catalyst veneer process calcination processing of carrier and active component.
Fig. 2 is the perspective view of catalyst veneer in the board-like denitrating catalyst module shown in Figure 1.Referring to shown in Figure 2, in one embodiment, said catalyst veneer 2 both sides longitudinally (direction of flow of flue gas) are arranged with feeler 2-1; Also be laid with active component in said feeler 2-1 both sides.Feeler 2-1 is set on catalyst veneer 2, has played the effect of the mechanical strength that improves whole board-like denitrating catalyst module.Wherein, both sides are laid with the said catalyst veneer and the said feeler process calcination processing of carrier and active component.
Further,, longitudinally be arranged at intervals with at least two said feelers, make that like this mechanical strength of whole board-like denitrating catalyst module is higher in each side of said catalyst veneer.
In one embodiment, corresponding feeler contacts between adjacent two catalyst veneers; Face two catalyst veneers mutually, and this faces the feeler that faces mutually on two catalyst veneers mutually and surrounds an exhaust gases passes.Make that like this flue gas flow rate is even between the catalyst veneer, catalyst module and pending flue gas contact area are big, and flue gas resistance is low, and catalytic efficiency significantly improves.
In another embodiment, the catalyst veneer is the stainless steel sift orifice plate, and said active material is directly laminated on the stainless steel sift orifice plate.
In another embodiment, the catalyst veneer is a stainless steel plate mesh, is provided with carrier in said catalyst veneer both sides and feeler both sides, and said active component is through said carrier be laid in said catalyst veneer both sides and feeler both sides.Wherein, said carrier comprises TiO
2(titanium dioxide) is for example with glass fibre and TiO
2Be carrier, active component is dispersed on the carrier.
In one embodiment, said active component is V
2O
5(vanadic anhydride), in addition, in active component, adding has WO
3(tungstic acid) or MoO
3(molybdenum trioxide) reduces SO on the basis that keeps the catalytic reduction of NOx activity as co-catalyst as far as possible
