〔発明の目的〕
（産業上の利用分野）
本発明は、各種気体や液体の浄化、その他各種の殺直に
使用される殺菌灯装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a germicidal lamp device used for purifying various gases and liquids and for various other types of direct killing.
（従来の技術）
殺菌灯は、バルブの両端に電極を対設し、内部に始動用
希ガスと水銀を封入して構成され、その点灯原理はけい
光ランプと全く同様であり、異なる点は叶い光体を使用
しないこと、およびバルブを構成するガラスチューブと
して遠紫外線透過率に優れたガラスや石英ガラスを使用
した点である。(Prior art) A germicidal lamp consists of a bulb with electrodes placed opposite each other and a starting rare gas and mercury sealed inside.The lighting principle is exactly the same as that of a fluorescent lamp, with the difference being that The two features are that no light source is used, and the glass tube that makes up the bulb is made of glass or quartz glass, which has excellent far-UV transmittance.
このような殺菌灯は、水銀蒸気中の放電によって生じる
遠紫外線を放射するので、上下水の浄水場で水の殺菌に
使用されたり、また各種ガスの殺菌あるいは物の生産、
加工、処理等の広い分野で使用される。These germicidal lamps emit far ultraviolet rays generated by discharge in mercury vapor, so they are used for water sterilization at water and sewage treatment plants, as well as for sterilization of various gases, production of products,

しかしながら、従来の殺菌灯は、電極間距離α当りの入
力がＩＷ（ワット）以下で、１灯当りの全入力もせいぜ
い１００Ｗ程度であって、比較的低出力であった。However, conventional germicidal lamps have a relatively low output, with an input per electrode distance α of less than IW (watt) and a total input per lamp of about 100 W at most.
低出力の殺菌灯は当然ながら殺菌能力も低く。Low-output germicidal lamps naturally have low sterilizing ability.
したがって浄化施設などの大形装置に使用しようとする
と、多数可使用しなければならず、付属部品もまた多数
を要す。Therefore, if it is to be used in a large-scale device such as a purification facility, it must be usable in large numbers, and a large number of accessory parts are also required.
このような事情から、最近、コンパクトで大出力の殺菌
灯の開発が要請されている。この殺菌灯では、水銀蒸気
中の放電によって生じる２５４ｎｍの遠紫外線、つまり
殺菌線を効率よく得るために。Under these circumstances, there has recently been a demand for the development of compact, high-output germicidal lamps. This germicidal lamp efficiently obtains 254 nm far ultraviolet rays, or germicidal radiation, generated by discharge in mercury vapor.
水銀の蒸気圧をいかに良好に制御するかということが問
題となる。すなわち、コンパクトで大出力の殺菌灯を達
成するには９点灯中の入力密度（単位長さ当りの入力＝
Ｗ／ｃｙｒｔ ）を従来のＩ Ｗ／ｃｔｓ以上にも増
やしてやればよいが、入力密度を増すと発熱量も多くな
り、最冷部温度が不所望に上昇して水銀の蒸気圧の上昇
をきたし、そのため殺菌線の放射量が低下することにな
る。The problem is how to best control the vapor pressure of mercury. In other words, to achieve a compact and high-output germicidal lamp, the input density during lighting (input per unit length =
W/cyrt) above the conventional IW/cts, but increasing the input density also increases the amount of heat generated, which undesirably increases the temperature of the coldest part and causes an increase in the vapor pressure of mercury. Therefore, the amount of germicidal radiation is reduced.
（発明が解決しようとする問題点）
上記のようにコンパクトで大出力の殺菌灯を得ようとす
ると、最冷部温度が上昇して水銀蒸気圧が不所望に上昇
し、このため殺菌線の出力が低下するという問題があっ
た。(Problems to be Solved by the Invention) When trying to obtain a compact and high-output germicidal lamp as described above, the temperature of the coldest part increases and the mercury vapor pressure undesirably increases. There was a problem that the output decreased.
そこで本発明は以上の欠点を除去するもので。Therefore, the present invention aims to eliminate the above drawbacks.
遠紫外線すなわち殺菌線が効率よく得られるコンパクト
で入力密度がＩ Ｗ／ｃｐｎ以上の大出力の殺菌灯装置
を提供することを目的とする。It is an object of the present invention to provide a compact germicidal lamp device capable of efficiently obtaining deep ultraviolet rays, that is, germicidal radiation, and having a high output power with an input density of I W/cpn or more.
（問題点を解決するための手段）
殺菌灯の最冷部に接触する冷却装置を設け、この冷却装

), the heated cooling water passes through the discharge hole (6) and the circulation pipe (16B), enters the heat exchanger I, is cooled, and is circulated through the path that enters the cooling device (4) again by the pump a3. Since the temperature of the coldest part of the germicidal lamp (1) can be maintained at an appropriate temperature at all times, it is possible to efficiently and stably output the germicidal radiation.
