Embodiment 1
[0036] Such as figure 1 As shown, the waste flat plate denitrification catalyst recycling aggregate separation method includes the following steps:
[0037] S1, mechanical cleaning
[0038] The waste flat denitrification catalyst first enters the dust removal device for mechanical soot blowing to remove the fly ash on the surface of the catalyst, so that the aggregate of the catalyst is fully exposed; for the thicker part of the catalyst surface, it is manually cleaned with a spatula and other tools before mechanical cleaning. soot blowing;
[0039] S2, ultrasonic cleaning
[0040] Put the mechanically cleaned catalyst in the deionized water cleaning tank, and use the energy penetration of ultrasonic waves to clean for 2 hours, so as to enhance the exchange effect between the blockages in the micropores on the surface of the catalyst and the external solute molecules, and achieve the effect of cleaning the poisons in the micropores , so that the microstructure of the spent ...
Embodiment 2
[0052] Such as figure 1 As shown, the waste flat plate denitrification catalyst recycling aggregate separation method includes the following steps:
[0053] S1, mechanical cleaning
[0054] The waste flat denitrification catalyst first enters the dust removal device for mechanical soot blowing to remove the fly ash on the surface of the catalyst, so that the aggregate of the catalyst is fully exposed; for the thicker part of the catalyst surface, it is manually cleaned with a spatula and other tools before mechanical cleaning. soot blowing;
[0055] S2, ultrasonic cleaning
[0056] Put the mechanically cleaned catalyst in the deionized water cleaning tank, and use ultrasonic energy to penetrate for 3 hours to enhance the exchange effect between the blockage in the micropores on the surface of the catalyst and the external solute molecules, and achieve the effect of cleaning the poison in the micropores , so that the microstructure of the spent catalyst is effectively restor...
Embodiment 3
[0068] Such as figure 1 As shown, the waste flat plate denitrification catalyst recycling aggregate separation method includes the following steps:
[0069] S1, mechanical cleaning
[0070] The waste flat denitrification catalyst first enters the dust removal device for mechanical soot blowing to remove the fly ash on the surface of the catalyst, so that the aggregate of the catalyst is fully exposed; for the thicker part of the catalyst surface, it is manually cleaned with a spatula and other tools before mechanical cleaning. soot blowing;
[0071] S2, ultrasonic cleaning
[0072] Put the mechanically cleaned catalyst in the deionized water cleaning pool, and use ultrasonic energy to penetrate for 4 hours to enhance the exchange effect between the blockages in the micropores on the surface of the catalyst and the external solute molecules, and achieve the effect of cleaning the poisons in the micropores , so that the microstructure of the spent catalyst is effectively rest...
