摘要
为防治煤矿硫化氢气体,建立H_2S分解模拟实验系统,采用臭氧紫外光分解技术进行硫化氢的分解。对影响H_2S分解效率的灯光组数、臭氧、风速等因素进行了研究,实验表明H_2S分解效率随H_2S入口浓度的增加而降低,随灯光组数的增加而提高,随风速的增加而降低、随臭氧作用时间的增加而提高。
In order to prevent and control hydrogen sulfide gas in coal mine, we establish H_2S decomposition simulation experiment system, and use ozone ultraviolet light decomposition technique to carry out the decomposition of hydrogen sulfide.These factors including the number of light sets, ozone, wind speed affecting the decomposition rate of H_2S were studied. The experimental results show that the degradation rate of H_2S decreases with the increase of the inlet concentration of H_2S, and increases with the increase of ozone treatment time, and decreases with the increase of wind speed.
