项目摘要

A new type of corona reactor was proposed for the contaminated air cleaning in the automobile tunnel or in the underground parking space. The reactor with the discharge electrode over water was designed as the reactor for removal of dust and NOx simultaneously. The reactor was expected to make the better proceeding of dust collection and the plasma chemical reactions for NOx removal by the ions, ozone and OH radical produced in the corona space. In order to get the fundamental data of the corona discharge over the water surface, positive and negative V-I characteristics and the ozone production were measured with the multi needle and the saw-edge type of the discharge electrodes. The pulse corona characteristics were also measured with some different waveforms of the applied pulse voltage. The experiments were carried out under the atmospheric pressure and room temperature. Both DC and the pulse corona to the water surface showed the stable V-I characteristics though the surface of water was waved by the corona wind. The positive streamer corona showed the more ozone production than the negative one both in the DC and in the pulse corona. Some dust and NOx treatment tests by the model corona reactor were carried out with diesel engine exhaust gas. The corona discharge to the water surface was confirmed to induce the better conditions for the proceeding of the NO oxidation and the NO_2 dissolution into water in the NOx removal processes as well as dust catching.

提出了一种新型电晕反应器，用于汽车隧道或地下停车场的污染空气净化。将放电电极置于水面上的反应器设计为同时除尘和脱氮的反应器。该反应器利用电晕空间中产生的离子、臭氧和OH自由基等离子体化学反应来实现除尘和脱硝的目的。为了获得水面电晕放电的基础数据，采用多针锯齿形放电电极，测量了水面电晕放电的正负伏安特性和臭氧产生量。在不同的脉冲电压波形下，测量了脉冲电晕特性。实验在常压和室温下进行。直流电晕和脉冲电晕对水面的作用都表现出稳定的V-I特性，尽管电晕风会使水面产生波动。在直流和脉冲电晕中，正流光电晕比负流光电晕产生更多的臭氧。利用该模型电晕反应器对柴油机尾气进行了粉尘和NOx的处理试验。研究结果表明，在脱硝除尘过程中，对水面的电晕放电为NO的氧化和NO_2的溶解提供了较好的条件。
