Embodiment 1
[0033] Add the high-efficiency composite additive in the present invention in the 1# absorption tower and account for 550ppm of the total amount of the slurry, according to the following components and mass percentages: 40% adipic acid, 20% sodium acetate, 20% potassium acetate, dodecane Sodium phenyl sulfonate 10%, manganese sulfate 3%, polysiloxane 2%, sodium chloride 5%. At a unit load of 300MW, the SO2 inlet concentration of the desulfurization tower is 4195.3mg / Nm 3 , running 5 circulating slurry pumps, the concentration at the outlet of the desulfurization tower can reach 22.1mg / Nm 3 , the desulfurization efficiency is increased by 1.5%, and the slurry limestone is saved by 13.8%. The comparison of the main indicators of the blank test with additives and without additives is shown in Table 1.
Embodiment 2
[0035] Add the high-efficiency composite additive in the present invention to 1# absorption tower and account for 520ppm of the total amount of slurry, according to the following components and mass percentages: acetic acid 20%, adipic acid 20%, sodium formate 10%, sodium citrate 30% , Sodium Lauryl Sulfate 10%, Manganese Chloride 3%, Polyoxyethylene Ether 2%, Sodium Chloride 5%. When the load of the unit is 300MW, the SO2 inlet concentration of the desulfurization tower is 4215.4mg / Nm3 , running 5 circulating slurry pumps, the concentration at the outlet of the desulfurization tower can reach 25.9mg / Nm 3 , the desulfurization efficiency is increased by 1.5%, and the slurry limestone is saved by 10.9%. The comparison of the main indicators of the blank test with additives and without additives is shown in Table 2.
Embodiment 3
[0037] Add the high-efficiency composite additive in the present invention in the 1# absorption tower and account for 500ppm of the total amount of the slurry, according to the following components and mass percentages: 20% formic acid, 20% adipic acid, 20% sodium formate, 20% sodium acetate, Sodium Lauryl Sulfate 6%, Lauryl Sultaine 4%, Manganese Chloride 3%, Polysiloxane 2%, Sodium Sulfate 5%. When the unit load is 300MW, the SO2 inlet concentration of the desulfurization tower is 4227.8mg / Nm 3 , running 5 circulating slurry pumps, the concentration at the outlet of the desulfurization tower can reach 22.7mg / Nm 3 , the desulfurization efficiency is increased by 1.5%, and the slurry limestone is saved by 15.6%. Add additive and do not add additive blank test main index contrast, as shown in table 3; Add the real-time concentration monitoring of absorption tower outlet flue gas after adding additive of the present invention, as shown in Table 3 figure 1 shown. figure 1 It r...
