Abstract

<P>PROBLEM TO BE SOLVED: To provide a cylindrical type rotary streamer generator capable of obtaining an increase in current and stability of discharge and passing an exhaust gas through plasma for a long period of time. <P>SOLUTION: A rotary inner cylinder fitted with a streamer generation element 1 comprising a metal thin wire is arranged at the center of an outer cylinder 2. When a plus voltage is applied to the streamer generation element 1 from an application voltage charging port 5 and a minus voltage is applied to the outer cylinder 2 wound with a metal plate 18, streamer discharge 15 is generated. The rotary inner cylinder is driven by a motor 13 and the exhaust gas is sucked by a fan 14. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

発明の詳細な説明Detailed Description of the Invention

低温大気圧プラズマは排ガス処理方法の一つとして注目を集めている。その中でもストリーマ放電は排ガス処理に有効性が認められストリーマの発生方法、効率の良い発生素子、配置方法等が研究されている。  Low temperature atmospheric pressure plasma is attracting attention as one of the exhaust gas treatment methods. Among them, streamer discharge is recognized as effective for exhaust gas treatment, and streamer generation methods, efficient generation elements, arrangement methods, and the like have been studied.

ストリーマ放電を発生させる構造は[図9]のように線−平板電極、[図10]のように針−平板電極、[図11]平板−平板電極、[図12]線−円筒電極等がありストリーマ放電を発生させている。放電電流の増加は排ガスの分解率に関係しているが放電電流を増加しようと印加電圧を高めるとストリーマ放電からスパーク放電に移行してしまう。ストリーマ放電の安定性と放電電流の増加は課題の一つであった。現状の構造では筒状の構造全体を高濃度プラズマ状態にさせることは無理があった。ストリーマ放電は1方向又は2方向又は全面放電と色々あるがいずれの方法も放電電流は少なく放電の安定性に欠けていた。又連続する排ガス処理は効率を向上させるためには排ガスを長時間高濃度プラズマの中を通過させる必要性がありストリーマ発生装置の構造も課題の一つで有った。  The structure for generating the streamer discharge is a wire-plate electrode as shown in [FIG. 9], a needle-plate electrode as shown in [FIG. 10], a [FIG. 11] plate-plate electrode, a [FIG. 12] line-cylindrical electrode, and the like. There is a streamer discharge. The increase in the discharge current is related to the decomposition rate of the exhaust gas, but if the applied voltage is increased to increase the discharge current, the streamer discharge is shifted to the spark discharge. The stability of streamer discharge and the increase of discharge current were one of the problems. In the current structure, it was impossible to bring the entire cylindrical structure into a high concentration plasma state. There are various streamer discharges, one-way, two-way, or full-surface discharge, but each method has a small discharge current and lacks discharge stability. In order to improve the efficiency of the continuous exhaust gas treatment, it is necessary to pass the exhaust gas through the high-concentration plasma for a long time, and the structure of the streamer generator has been one of the problems.

[図1][図2]のように外筒2,の中央にストリーマ発生素子1,を取り付けた回転する内筒3,を配置し発生素子1,に+電圧を印可電圧投入口5,より印可する。外筒の電極は周面を金属で覆い−電圧を印可する。回転する内筒3,はモータ13,で駆動する。排ガスはファン14,によって吸引する。ストリーマ放電は15,のように放電する。  [FIG. 1] As shown in FIG. 2, a rotating inner cylinder 3 having a streamer generating element 1 attached thereto is arranged in the center of the outer cylinder 2, and a positive voltage is applied to the generating element 1 from a voltage input port 5. Apply. The outer cylinder electrode is covered with metal and applied with voltage. The rotating inner cylinder 3 is driven by a motor 13. The exhaust gas is sucked by the fan 14. The streamer discharge is discharged as 15.

発明の効果The invention's effect

ストリーマ発生素子1、の構造は金属細線を薄く並べるこ事を採用したことにより針、10,線、9,平板、11,の構造より同等の印可電圧で放電電流の増加と安定した放電を得ることが出来ようになり高濃度の安定したプラズマ状態を作ることが出来る。又回転による冷却効果によって放電電極の冷却効果が得られスパーク状態になりにくく相乗効果で安定したストリーマ放電状態を維持出来る。ストリーマ素子1の長さは自由度があり装置の長さに合わせること出来る。又放電電流の安定したストリーマ素子1、を回転させることにより筒を通過する排ガスは長時間広域高濃度プラズマ状態の中を通過することが可能になり排ガスの分解効率が上がりが排ガス処理が可能になった。  The streamer generating element 1 has a structure in which thin metal wires are arranged in a thin line, so that an increase in discharge current and stable discharge can be obtained with an equivalent applied voltage compared to the structure of needles 10, wires, 9, flat plates, and 11. And a stable plasma state with a high concentration can be created. In addition, the cooling effect by the rotation provides the cooling effect of the discharge electrode, and it is difficult to be in a spark state, and a stable streamer discharge state can be maintained by a synergistic effect. The length of the streamer element 1 is flexible and can be adjusted to the length of the apparatus. Further, by rotating the streamer element 1 having a stable discharge current, the exhaust gas passing through the cylinder can pass through the high-density plasma state over a wide area for a long time, so that the decomposition efficiency of the exhaust gas is increased and the exhaust gas can be treated. became.
