Ammonia regeneration method and device for activated coke

The invention discloses an ammonia regeneration method and an ammonia regeneration device for activated coke. The device comprises an activated coke regeneration tower 1, a flue 2, an electric heater 3, an NH3 measurement device 4, an NH3 spraying device 5, a computer control end 11 and a fan 12, wherein a baffle plate is arranged in the activated coke regeneration tower 1 and divides the activated coke regeneration tower 1 into a regeneration heating reaction region I and a regeneration cooling region II; the electric heater 3 and the NH3 measurement device 4 are respectively arranged on the flue 2 between the region I and the region II of the activated coke regeneration tower 1; the NH3 spraying device 5 is arranged on the flue 2 between the NH3 measurement device 4 and the region II; the fan 12 is arranged on the flue 2 between the NH3 spraying device 5 and the region II; and the NH3 measurement device 4, the NH3 spraying device 5 and the fan 12 are respectively connected with the computer control end 11. 1 to 10 percent of ammonia is added into the sweep gas, so that the energy consumption is reduced, and the utilization efficiency of the activated coke is improved.
