Abstract
The regeneration tower is one of the core equipment of the activated coke desulfurization and denitration system.Discharging at an excessive temperature can affect the equipment safety,and even burn the regeneration tower in serious cases.Taking the regeneration tower of the sintering machine head flue gas activated coke integrated dry desulfurization and denitration project of a steel plant in Qian'an as an example,this paper analyzes the causes of the over-temperature of the discharge of the activated coke regeneration tower,and proposes a solution.The study indicated that the non-uniformity of the material circulation of the activated coke is the primary cause of the over-temperature of the discharge.Through the improvement of the discharging shell,the discharging space in the discharging shell is uniformly improved into multiple grids,thus solving the problem of over-temperature in the discharge of the regeneration tower.关键词
