Activated coke regeneration and circulation step: the fresh activated coke that the activated coke of discharging from the first feed opening of the first desulfurization adsorption tower and batcher add is sent into screening plant by the first conveyer and is sieved, and the activated coke that meets the desulfurization requirement enters the second tower top feed bin and then enters the second desulfurization adsorption tower and adsorb SO
2Activated coke after absorption is discharged from the second feed opening of the second desulfurization adsorption tower bottom, enter second conveyor, by second conveyor, sent in regeneration reactor, by the thermal treatment zone, renewing zone, cooling zone, activated coke is regenerated successively, activated coke after regeneration is discharged and is sent into the first tower top feed bin by the 3rd conveyer by the activated coke discharging opening, and activated coke enters the first desulfurization adsorption tower absorption SO
2, then discharged by the first feed opening of the first desulfurization adsorption tower, enter next time and recycle.
10. the energy-efficient synthesis desulfurating purification method of the activated coke for different flue gases as claimed in claim 9, it is characterized in that: the flue-gas temperature that described the first desulfurization fume pipeline imports is 50-100 ℃, and the flue-gas temperature that described the second desulfurization fume pipeline imports is over 100 ℃.
