摘要/Abstract

摘要： 针对目前粗放的活性炭喷射工艺物料消耗大的问题，为提高单个喷射点的活性炭扩散面积，搭建了活性炭干粉喷射实验台。对3种喷嘴进行实验，结果表明：其干粉喷射效果明显优于管子直喷效果，距喷嘴750 mm截面处扩散面积分别比管子直喷时扩大了73.58%、201.89%、137.74%；喷嘴中内置旋流叶片对活性炭干粉喷射的改善效果不明显。通过采用商业CFD软件，开发了活性炭干粉喷射的数值模拟方法，并通过实验验证了模型的合理性。该活性炭干粉喷射模型可用于指导实际工程项目科学布置活性炭喷射点。

Abstract: In view of the high material consumption for the present activated carbon injection process, in order to expand the diffusion area of single activated carbon injection points, the activated carbon powder injection test bench was build. Then based on the experiment results for the three types of nozzles, it was found out that the powder injection outperformed the pipe direct injection, in which the diffusion area at 750 mm away from the nozzle was expanded by 73.58%, 201.89% and 137.74% respectively compared with direct pipe injection, while no significant diffusion area improvement was observed for activated carbon powder injection with built-in swirl vane. Additionally, by means of commercial CFD software, the numerical simulation method of activated carbon dry powder injection was developed, and the effectiveness of the model was verified through experimental studies. Therefore, the activated carbon dry powder injection model can be used as a guidance in the actual engineering project to arrange injection points scientifically.

Key words: coal-fired power plant, activated carbon injection, flue gas mercury-removing, numerical simulation, powder nozzle
