Description
本発明は、生ごみや汚泥などの乾燥処理に伴って発生する臭気成分を含んだ臭気ガスとか、水溶性切削液、アルカリ洗浄廃液、メッキ廃液、含水廃油などの各種廃液の濃縮処理に伴って発生する臭気成分を含んだ臭気ガスなど、各種の臭気ガスをオゾンにより脱臭処理するオゾン酸化脱臭装置に関する。 The present invention relates to the concentration treatment of various waste liquids such as odor gas containing odor components generated by drying treatment such as garbage and sludge, water-soluble cutting fluid, alkali cleaning waste fluid, plating waste fluid, and hydrated waste oil. The present invention relates to an ozone oxidation deodorization apparatus that deodorizes various odor gases such as odor gas containing odor components generated by ozone.
オゾン酸化脱臭装置としては、従来一般に、次のようなものが知られている。
すなわち、ケーシング内に、空気（臭気ガス）の流動方向に紫外線ランプと、酸化チタンを担持させた集塵電極とが設けられている。
集塵電極が、流動する空気に対してフィルター機能を持たせるように空気の流動方向に直交して設けられている。
これにより、ケーシング内でオゾンを発生させ、空気に含まれる臭気成分に対して脱臭処理を行うように構成されている（特許文献１参照）。
That is, an ultraviolet lamp and a dust collecting electrode carrying titanium oxide are provided in the casing in the flow direction of air (odor gas).
The dust collecting electrode is provided perpendicular to the air flow direction so as to provide a filter function for the flowing air.
Thereby, it is comprised so that ozone may be generated in a casing and the deodorizing process may be performed with respect to the odor component contained in air (refer patent document 1).
しかしながら、従来例の場合、集塵電極を空気の流動方向に直交して設けることにより、空気とオゾンとの接触効率を高めて脱臭効率を向上するようにしているが、ケーシングの内容積の割に空気とオゾンとを接触する容積が小さく、脱臭効率を十分向上できているとは言い難く、未だ改善の余地があった。 However, in the case of the conventional example, by providing the dust collecting electrode perpendicular to the air flow direction, the contact efficiency between the air and ozone is increased to improve the deodorization efficiency. Furthermore, the volume of contact between air and ozone is small, and it cannot be said that the deodorization efficiency is sufficiently improved, and there is still room for improvement.
