Embodiment 1
[0021] will already contain the catalyst component (TiO 2 , V 2 o 5 、WO 3 ) dry monomer (the dry monomer will contain the catalyst component (TiO 2 , V 2 o 5 、WO 3 ) and liquid substances are extruded into honeycomb monomers and fully dried at 115°C. The manufacturing method is the prior art. ) after sawing and cutting into a specified length (according to the different requirements of flue gas conditions of different denitrification projects, generally 600-1300mm), the catalyst is manufactured according to the following steps:
[0022] (1) Dip 20--30 mm of one end of the monomer in aluminum dihydrogen phosphate hardening solution with a density of 1.43 kg / L for 7 seconds;
[0023] (2) Take out the monomer and let stand for 8 seconds;
[0024] (3) Use a compressed air blower to blow air for 20 seconds to blow off the excess hardening liquid on the surface of the monomer impregnated end;
[0025] (4) Place the monomer impregnated in the hardening solution in a calciner...
Embodiment 2
[0027] The density of the hardening solution was adjusted to 1.45kg / L, and other conditions and hardening treatment were the same as in Example 1 to prepare a catalyst.
Embodiment 3
[0029] The density of the hardening solution was adjusted to 1.42kg / L, and other conditions and hardening treatment were the same as in Example 1 to prepare a catalyst.
