摘要

SF₆作为一种温室气体,其工业废气的回收和降解是环境领域的研究热点。该文基于双层介质阻挡放电（DBD）反应器,研究玻璃珠、γ-Al₂O₃颗粒填充和无填充体系下SF₆的降解过程。结果表明,填充介质的加入能够改变反应器的物理参数,增加DBD放电过程的等效电容,提高放电功率。此外,两种填充介质的加入都可以有效地提高SF₆的降解率（DRE）和能量效率（EY）,在γ-Al₂O₃颗粒填充体系中,2%SF₆在110W下最大降解率达到85.97%,能量效率达到9.17g/(kW·h),远超无填充的情况。两种填充介质的加入影响了SF₆分解产物的产量。玻璃珠的加入对产物种类的影响不明显,而γ-Al₂O₃颗粒填充会导致SF₆倾向于产生SO₂,并抑制SOF₂、SO₂F₂和SOF₄的生成,同时SO₂的产量随输入功率的增加而增加。γ-Al₂O₃颗粒填充在有效提高降解率和能量效率的同时,抑制SO₂F₂等难以处理的产物生成。以上结果表明,加入合适的填充介质如γ-Al₂O₃颗粒能够有效地促进SF₆的无害化降解。

Abstract：

As a greenhouse gas, the recovery and degradation of SF₆ industrial waste gas is a research hotspot in the field of environment. Based on the double-layer dielectric barrier discharge (DBD) reactor, the degradation process of SF₆ with glass beads, γ-Al₂O₃ particles and no packing system was studied. The results show that the addition of packing materials can change the physical parameters of the reactor and increase the effective capacitance of DBD discharge process and discharge power. In addition, the degradation removal efficiency (DRE) and energy yield (EY) of SF₆ can be effectively improved by adding two kinds of packing materials. In the γ-Al₂O₃ system, the maximum DRE of 2% SF₆ was 85.97% at 110W, and the EY reached 9.17g/(kW·h), far exceeding the case of no packing. The addition of two kinds of packing materials affects the amount of SF₆ decomposition products. The addition of glass beads has no obvious effect on the degradation product, while the packing of γ-Al₂O₃ particles will make SF₆ have a tendency to produce SO₂ and inhibit the formation of SOF₂, SO₂F₂ and SOF₄. At the same time, the output of SO₂ increases with the increase of input power. γ-Al₂O₃ particle packing can effectively improve DRE and EY while inhibiting the formation of refractory products such as SO₂F₂. The results show that adding suitable packing materials such as γ-Al₂O₃ particles can effectively promote the harmless degradation of SF₆.

Key words： Dielectric barrier discharge SF₆ degradation packing material γ-Al₂O₃
