| 中文摘要 |
| 采用DBD技术脱除工业废气中的H2S和CS2.12kV的电压下,分压为4kPa的H2S,放电5s,去除率接近100%;分压为1.33kPa的CS2,放电15s,其去除率可达80%.H2S和CS2的去除率都随其浓度的增加而下降.在实验室研究的基础上,设计了废气处理量为420m3/h、流速为10m/s的DBD净化装置,进行了实际含H2S和CS2的工业废气净化研究,H2S去除率可达89%,能量消耗为5.2W·h/m3.结果表明DBD技术对于处理含硫恶臭工业废气,具有实际应用价值. |
| 英文摘要 |
| Dielectric barrier discharge(DBD) technique was applied to remove H2S and CS2 in industrial waste gas. In the research of laboratory, when the voltage between two electrodes was 12 kV, 4×103Pa H2S was discharged in air for 5 seconds, about 100% of H2S was transformed into H2O and SO2;1.33×103Pa CS2 was discharged in air for 15 seconds, about 80% of CS2 was transformed into CO2、CO and SO2 . When the concentration of H2S and CS2 increased, the decomposition of them decreased. Based on the results, a DBD purification apparatus which can dispose 420m3/h、10m/s waste gas was designed and manufactured, the removal rate of H2S can reach 89% and the energy consumption was 5.2 W·h/m3. It was concluded that the DBD technique is worth disposing malodorous industrial waste gases contained H2S and CS2. |
