The specific embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to 4: the protection network of described protection denitrification catalyst module comprises catalyst module 1, screen frame 2, entrance point 3, the port of export 4, strengthens gusset 5, protection network 6, hangs sheet 7 etc.
As shown in Figure 1, the utility model comprises that inside is provided with the catalyst module 1 of denitrating catalyst, and one end of catalyst module 1 is entrance point 3, and the other end is the port of export 4, sidepiece at catalyst module 1 arranges reinforcement gusset 5, in order to improve the intensity of catalyst module 1; At described entrance point 3 and the port of export 4, screen frame 2 is installed respectively, screen frame 2 is rectangular latticed, and protection network 6 is set in the grid of screen frame 2;
The entrance point 3 of the size of described screen frame 2 and catalyst module 1 and the port of export 4 in the same size, the string diameter of protection network 6 is 0.1mm ~ 10mm, and the mesh of protection network 6 is circular, oval, rectangle or regular polygon, and the internal diameter of mesh is 1mm ~ 1000mm;
Described protection network 6 adopts the relevant materials such as iron, cobalt, nickel, steel, copper, zinc, aluminium to make;
As shown in Figure 1, Figure 3, on described screen frame 2, be provided with and hang sheet 7, hang sheet 7 and be provided with lifting hole(eyelet), conveniently catalyst module 1 is sling.
In use, fire coal boiler fume enters denitrification catalyst module by Benitration reactor, and flue gas reacts with denitrification catalyst module by after mixing with ammonia, and ash-laden gas ceaselessly impacts catalyst.At entrance point, protection network is installed and can be effectively stoped the direct impact wear denitrating catalyst of fly ash granule in flue gas, part fly ash granule in flue gas is blocked in outside protection network, effectively protect denitrification catalyst module.After denitrification catalyst module middle part divided catalyst damages, the protection network of installing at the port of export, effectively prevents from that catalyst from caving in to drop, and causes secondary to destroy.
Example: in Mou power plant unit denitrating system denitrating catalyst project, entrance point flue gas flying dust is for being not less than 40g/Nm
3, for guaranteeing the safe and reliable operation of denitrating catalyst in denitrating system, at denitrification catalyst module middle outlet end and entrance point, two groups of protection networks are installed respectively.Entrance point place protection network adopts 304L stainless steel, and mesh is 5 * 5mm, and string diameter is 1.6mm.Port of export protection network adopts 304L stainless steel, and mesh is 1 * 1/2 inch, and string diameter is 1.6mm.Denitrification catalyst module is of a size of 1912 * 974 * 1000mm.After actual use, find, adopt protection network can effectively prevent that denitrification catalyst module from damaging and dropping.
