specific Embodiment approach 1
[0019] Specific implementation mode one: as figure 1 As shown, a flue gas mercury removal device includes a reactor shell 1, the lower part of the reactor shell 1 is provided with an air inlet 2, and the upper part is provided with an air outlet 3, wherein the inner cavity of the reactor shell 1 is Three layers of porous support plates 4 are arranged between the air port 2 and the air outlet 3 , and each support plate 4 is provided with an adsorption packing layer 5 . During implementation, described air outlet 3 places are provided with aspirator 6, and during specific implementation, described aspirator 6 also can be arranged in the pipeline that communicates with air outlet; The adsorption filler in described adsorption filler layer 5 is composed of activated carbon particles .
[0020] In order to verify the technical solution of this embodiment and optimize the specific parameter settings, the applicant, based on the above-mentioned device structure, changed the porous s...
specific Embodiment approach 2
[0027]Embodiment 2: In Embodiment 2, on the basis of Embodiment 1, the adopted adsorption filler is replaced by a new type of adsorption filler independently developed by the applicant, and the rest of the implementation conditions remain unchanged. The new adsorption filler includes the following preparation steps: using 72% of fly ash, 7% of calcium oxide, 3% of sodium bromide, 12% of Hunan clay, 3% of polyethylene, and 3% of rice husk to mix, mix Add water and mix thoroughly, then extrude and granulate to form granules with a particle diameter of 30-50mm, and then sinter and shape at a high temperature of 900-1100°C.
[0028] First, in order to verify and optimize the mercury absorption effect of the new adsorption filler, the applicant conducted a large number of tests to optimize the parameters such as the molding particle size, sintering temperature, and sintering holding time during the preparation process of the above-mentioned new adsorption filler. During the experim...
