Method for preparing cooled agglomerated pellets by using dry method electric fly ash of converter gas

[0019] The following specific embodiments will further clarify the present invention. It should be understood that the following specific embodiments are only used to illustrate the present invention and not to limit the scope of the present invention.

[0020] The invention discloses a method for manufacturing cold solid pellets by using converter gas dry electro-dedusting ash, which includes the following steps:

[0021] a. Digest the converter gas dry electric dust removal ash, the quality of the water added in the digestion treatment is 8-12% of the converter gas dry electric dust removal ash quality, and the digestion time is 14.5-15.5 hours;

[0022] b. Add a 12% sodium polyacrylamide aqueous solution to the converter gas dry electric dust removal ash after digestion and stir to form a uniform mixture. The mass percentage of the components of the mixture is: converter gas dry electric dust removal ash 85.1 to 88.5%, 5.3 to 7.5% of sodium polyacrylamide aqueous solution, and 4.4 to
