以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(実施の形態1)
以下、本発明の第1の実施の形態について図面を参照しながら説明する。
(Embodiment 1)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

図1および図2は、本発明の一実施形態における浄化装置の概略図および断面図である。なお、以下では空気などの気体について説明するが、固体でも同様である。   1 and 2 are a schematic view and a cross-sectional view of a purification device according to an embodiment of the present invention. In addition, although gas, such as air, is demonstrated below, it is the same also with solid.

浄化ユニット1は、気体の流路内に配置されるものであり、放電電極21が配置され、放電電極21の対向に対向電極31が配置されていて、放電電極21と対向電極31との間に形成される放電領域9が構成されている。7は浄化ユニット上流気流、8は浄化ユニット下流気流を示す。   The purification unit 1 is arranged in a gas flow path, a discharge electrode 21 is arranged, a counter electrode 31 is arranged opposite to the discharge electrode 21, and between the discharge electrode 21 and the counter electrode 31. A discharge region 9 is formed. Reference numeral 7 denotes the purification unit upstream airflow, and 8 denotes the purification unit downstream airflow.

高電圧印加装置4は、放電電極21に接続する電極(プラスまたはマイナス)41と、対向電極31に接続するアース電極42とを有し、放電電極21と対向電極31との間に、放電を発生させ得る高電圧を印加するように構成されている。この高電圧印加装置4としては、高圧トランスで昇圧するようにした電装回路などが使用される。しかし所望の高電圧を印加できるものであれば、これに限定されず使用可能である。   The high voltage application device 4 has an electrode (plus or minus) 41 connected to the discharge electrode 21 and a ground electrode 42 connected to the counter electrode 31, and discharges between the discharge electrode 21 and the counter electrode 31. A high voltage that can be generated is applied. As the high voltage applying device 4, an electrical circuit that is boosted by a high voltage transformer is used. However, any device capable of applying a desired high voltage can be used without being limited to this.

水発生手段5は、例えばペルチェ素子など無給水で水を発生させるのもであり、放電電極21に密着させ設けておく。これにより、放電電極21が露点以下の温度になると放電
電極21の表面に結露水10が発生する。例えば、温度が22℃で湿度が30%のとき、放電電極21が露点すなわち3.6℃以下の温度になると放電電極21の表面に結露水10が発生する。なお、ペルチェ素子を対向電極31に密着させ設けておいてもかまわない。
The water generating means 5 generates water without supplying water, such as a Peltier element, and is provided in close contact with the discharge electrode 21. Thereby, when the discharge electrode 21 becomes a temperature below the dew point, the dew condensation water 10 is generated on the surface of the discharge electrode 21. For example, when the temperature is 22 ° C. and the humidity is 30%, dew condensation water 10 is generated on the surface of the discharge electrode 21 when the discharge electrode 21 reaches a dew point, that is, a temperature of 3.6 ° C. or lower. Note that a Peltier element may be provided in close contact with the counter electrode 31.

さらに、ヒートシンク6は、水発生手段5に密着させ設けておく。例えば水発生手段5をペルチェ素子とすると、一方が冷却面であれば他方は放熱面になり、この放熱面に、ヒートシンク6を密着することにより効率よく放電電極21が露点以下の温度になる。   Furthermore, the heat sink 6 is provided in close contact with the water generating means 5. For example, if the water generating means 5 is a Peltier element, if one is a cooling surface, the other is a heat radiating surface. The heat sink 6 is in close contact with the heat radiating surface, so that the discharge electrode 21 is efficiently brought to a temperature below the dew point.

12は放電電極21の周囲を囲むように配設した防風壁である。防風壁12があることにより、放電電極21の周囲の環境が限定される。すなわち、浄化ユニット上流7からの気流の温度が高くても、防風壁12があることにより、放電電極21が水発生手段5、たとえばペルチェ素子で冷却されると、周囲環境も冷却され、効率よく放電電極21が露点以下の温度になる。   Reference numeral 12 denotes a windbreak wall disposed so as to surround the periphery of the discharge electrode 21. Due to the windbreak wall 12, the environment around the discharge electrode 21 is limited. That is, even if the temperature of the airflow from the purification unit upstream 7 is high, when the discharge electrode 21 is cooled by the water generating means 5, for example, a Peltier element, the surrounding environment is also cooled efficiently because of the windbreak wall 12. The discharge electrode 21 becomes a temperature below the dew point.

以下、上記構成における作用を説明する。   Hereinafter, the operation of the above configuration will be described.

高電圧印加装置4によって放電電極21と対向電極31との間に高電圧を印加するとともに、水発生手段9により放電電極21に結露水10を発生させる。これにより電極間に発生させた放電と結露水10を利用し、さらに防風壁12の効果により、放電領域9でラジカルやイオン等、およびそれらを含んだ微細な水粒子11を多量に生成し、放電領域下流すなわち、浄化ユニット下流8に放出させることができる。   A high voltage is applied between the discharge electrode 21 and the counter electrode 31 by the high voltage application device 4, and condensed water 10 is generated on the discharge electrode 21 by the water generating means 9. By using the discharge generated between the electrodes and the dew condensation water 10, and by the effect of the windbreak wall 12, a large amount of radicals, ions, and the like and fine water particles 11 containing them are generated in the discharge region 9, It can be discharged downstream of the discharge region, ie downstream 8 of the purification unit.

簡略化すると例えば   For example, if simplified

の反応がおこり、放電領域9の下流に、OHラジカルやイオン、H22ラジカルやイオン等、酸化力の高いラジカルやイオン等、およびそれらを含んだ水粒子11を豊富に生成することができる。 As a result of this reaction, downstream of the discharge region 9, OH radicals and ions, H 2 O 2 radicals and ions, etc., radicals and ions with high oxidizing power, and water particles 11 containing them may be generated in abundance. it can.

この生成されたラジカルやイオン等、およびそれらを含んだ水粒子11は酸化力が高く、微生物の外壁やタンパク質を破壊することができ、微生物は殺滅または不活化される。すなわち、生成されたOHラジカルやイオン、H2O2ラジカルやイオン等、酸化力の高いラジカルやイオン等、およびそれらを含んだ水粒子11を放電領域9の下流に放出させることにより、放出された領域を殺菌、脱臭、有害物質除去することができ、浄化される。   The generated radicals and ions and the water particles 11 containing them have high oxidizing power, can destroy the outer wall and protein of the microorganism, and the microorganism is killed or inactivated. That is, by releasing the generated OH radicals and ions, H 2 O 2 radicals and ions, radicals and ions having high oxidizing power, and water particles 11 containing them, the discharged region is discharged downstream. It can be sterilized, deodorized, harmful substances removed and purified.

印加すべき高電圧は、効率よく放電を発生させ得る高電圧であり、放電電極21と対向電極31との間隙の大きさ、放電領域の温度湿度環境によっても異なるが、たとえば放電電極21と対向電極31との間隙が約4mmで、温度が22℃、湿度が40%の時には、約4kV以上の高電圧が必要である。   The high voltage to be applied is a high voltage that can efficiently generate a discharge, and varies depending on the size of the gap between the discharge electrode 21 and the counter electrode 31 and the temperature and humidity environment of the discharge region. When the gap with the electrode 31 is about 4 mm, the temperature is 22 ° C., and the humidity is 40%, a high voltage of about 4 kV or more is required.

また負の高電圧を印加することによって、放電領域9でマイナスイオンを生成することができ、下流気流7としてマイナスイオンを含んだきれいな空気を供給して、リラックスできる雰囲気を提供することが可能となる。   Further, by applying a negative high voltage, negative ions can be generated in the discharge region 9, and it is possible to provide a relaxing atmosphere by supplying clean air containing negative ions as the downstream airflow 7. Become.

図3は、防風壁12に開口部を設けた開口部付防風壁121のときの概略図である。図4は、防風壁12のとき、すなわち開口部を設けていないときの、ユニット内気流13を含めた断面図である。図5は、防風壁12に開口部を設けた開口部付防風壁121のときのユニット内気流14を含めた断面図である。   FIG. 3 is a schematic view of the windbreak wall 121 with an opening provided with an opening in the windbreak wall 12. FIG. 4 is a cross-sectional view including the in-unit airflow 13 when the windbreak wall 12 is provided, that is, when no opening is provided. FIG. 5 is a cross-sectional view including the in-unit airflow 14 when the windbreak wall 121 is provided with an opening in the windbreak wall 12.

図4のユニット内気流13と、図5のユニット内気流14とに示すように、開口部付防風壁121にすることにより、対向電極31の開放部に向かって、イオン風が効率よく発生することができる。したがって、より多量に放電領域9でラジカルやイオン等、およびそれらを含んだ微細な水粒子を生成および発生させることができる。   As shown in the in-unit airflow 13 in FIG. 4 and the in-unit airflow 14 in FIG. 5, an ion wind is efficiently generated toward the open portion of the counter electrode 31 by using the windbreak wall 121 with an opening. be able to. Therefore, radicals, ions, etc., and fine water particles containing them can be generated and generated in a larger amount in the discharge region 9.

なお、開口部付防風壁121の開口部については、上記のように放電によるイオン風の影響が考慮でき、より多量にラジカルやイオン等、およびそれらを含んだ微細な水粒子を生成および発生させることができるものであれば、例えば、円形の開口部などその形状や個数についてはなんら限定しない。   In addition, about the opening part of the windbreak wall 121 with an opening part, the influence of the ion wind by discharge can be considered as mentioned above, and it produces | generates and produces | generates a fine water particle containing radicals, ions, etc. in large quantities. As long as it can be used, for example, the shape and number of circular openings are not limited.

また、防風壁12に、例えば帯電防止剤の塗布や、帯電防止シートを設けるなど、帯電処理を行うように構成する。酸化力の高い水粒子11は放電電極21がマイナスであれば、マイナスに帯電されている。したがって、防風壁12に帯電処理を行うことにより、防風壁12が帯電することにより、酸化力の高い水粒子11はクーロン力により引っ張られ、防風壁12に付着してしまい、より多量に生成、発生させることができなくなることを抑制することができる。   Further, the windbreak wall 12 is configured to perform a charging process such as application of an antistatic agent or provision of an antistatic sheet. The water particles 11 having high oxidizing power are negatively charged if the discharge electrode 21 is negative. Therefore, when the windbreak wall 12 is charged, the windbreak wall 12 is charged, so that the water particles 11 having high oxidizing power are pulled by the Coulomb force and adhere to the windbreak wall 12, and are generated in a larger amount. It can be suppressed that it cannot be generated.

図6は、防風壁の形状を円、楕円形、翼形などのように構成したの概略図である。防風壁の形状を開口部付円形防風壁122のように円、楕円形、翼形などのように構成する。これにより浄化ユニット通過気流などを効率よく通過させることができる。
なお、浄化ユニット通過気流などを効率よく通過させることができる形状であれば、なんら限定しない。
FIG. 6 is a schematic diagram of the windbreak wall configured as a circle, an ellipse, an airfoil, and the like. The shape of the windbreak wall is configured like a circle, an ellipse, an airfoil, etc., like the circular windbreak wall 122 with an opening. Thereby, the purification unit passing airflow and the like can be passed efficiently.
In addition, if it is a shape which can pass the purification | cleaning unit passage airflow etc. efficiently, it will not be limited at all.

なお、本浄化装置を、例えば風量の大きい空気清浄機や空気調和機に搭載すると、さらに浄化性能を向上させることができる。   In addition, if this purification apparatus is mounted in an air cleaner or an air conditioner having a large air volume, for example, the purification performance can be further improved.
