[0070] Example 1
[0071] A method for high-efficiency wet purification of flue gas containing elemental sulfur, the method comprising the following steps:
[0072] 1) Mixing flue gas and adsorbent: adding solid adsorbent to the flue gas containing elemental sulfur;
[0073] 2) Wet scrubbing: the flue gas containing solid adsorbent and elemental sulfur is passed into the scrubbing tower, and the flue gas is washed with a solution, and the flue gas is discharged after being washed and purified;
[0074] 3) Solid-liquid separation: the waste water generated after the flue gas is washed in the scrubber is added to the settling tank to achieve solid-liquid separation to obtain the supernatant and the settled sulfur-containing solid adsorbent.
[0075] Wherein, the solid adsorbent described in step 1) is activated carbon. The particle size of the solid adsorbent is 20 μm. The amount of solid adsorbent added is 1.3 times the ratio of the amount of elemental sulfur contained in the flue gas ...
