preparation example Construction
[0028] The preparation method of phosphorus-based coupling basic material:
[0029] Preparation Example 1:
[0030] Take the powder of phosphorus-based substance and alkaline material at a mass ratio of 4:1, and the powder particle size ranges from 300 to 1000 mesh; mix the two evenly by stirring, and the resulting mixture is the phosphorus-based coupled alkaline material.
[0031] Preparation example 2:
[0032] Take the powder of phosphorus-based substance and alkaline material at a mass ratio of 1:1, and the powder particle size ranges from 300 to 1000 mesh; mix the two evenly by stirring, and the resulting mixture is the phosphorus-based coupling alkaline material.
[0033] Preparation example 3:
[0034] The powder of phosphorus-based substance and alkaline material is taken at a mass ratio of 0.25:1, and the powder particle size ranges from 300 to 1000 mesh; the two are mixed evenly by stirring, and the obtained mixture is the phosphorus-based coupled alkaline material. ...
Embodiment 1
[0037] The composite inhibitor is ammonium dihydrogen phosphate and calcium oxide, with a particle size of 1000 mesh. It is sprayed into the flue area where the flue gas temperature is about 700°C. The usage amount accounts for 0.1% of the solid waste disposal amount. The efficiency is 91.6%.
