Description

本発明は、市街地道路、駐車場等に設置し、周辺大気を浄化するための大気汚染物質除去装置に関する。   The present invention relates to an air pollutant removing apparatus that is installed on an urban road, a parking lot, or the like and purifies the surrounding air.

都市部の交通量の増大による自動車排気ガスおよび大規模商業施設等の発生熱源からのＮＯｘなどによる大気汚染が大きな社会問題となっている。これらの大気汚染物質の除去手段として、二酸化チタンと活性炭との混合物からなる光触媒が開発されている。この光触媒は、近紫外線の照射により二酸化チタンが活性化し、大気との接触反応によりＮＯｘなどの汚染物質を常温で効率良く酸化除去するとともに、生じた酸化生成物を活性炭が吸着保持するように機能する。そして、酸化生成物の付着・堆積により機能が低下した光触媒は、水洗浄などで酸化生成物を洗い流すことで容易に再生することができる。   Air pollution due to NOx from automobile exhaust gas due to increased traffic in urban areas and heat sources generated from large-scale commercial facilities has become a major social problem. As a means for removing these air pollutants, a photocatalyst made of a mixture of titanium dioxide and activated carbon has been developed. This photocatalyst activates titanium dioxide by near-ultraviolet irradiation, functions to oxidize and remove pollutants such as NOx efficiently by contact reaction with the atmosphere at normal temperature, and activated carbon to adsorb and hold the generated oxidation products. To do. Then, the photocatalyst whose function is reduced by the adhesion and deposition of the oxidation product can be easily regenerated by washing away the oxidation product by washing with water or the like.

従来、光触媒シートの表面側に対向して配置した光源ランプと、光触媒シートの裏面側に背中合わせに配置した太陽電池パネルとを備え、この光源ランプを太陽電池で点灯させる有害ガス除去装置が提案されている（特許文献１参照）。

A cylindrical solar panel 5 is mounted on the outer peripheral surface of the main body frame 4. A plurality of ribs 2a are formed in the longitudinal direction on the inner periphery of the main body frame 2, and a cylindrical transmission filter 6 carrying a photocatalyst is positioned and disposed so as to contact the ribs 2a. The photocatalyst used in the present invention may be titanium dioxide alone, but if activated carbon is mixed with titanium dioxide, the resulting oxidized product is more favorably held.

透過フィルター６の上部には支持片７が設けられ、支持片７は本体フレーム２に着脱自在に固定されている。透過フィルター６内の下方にはファン８が配設され、本体フレーム２の上部には蓋部材９が載置され、蓋部材９の下面に紫外線ランプ１０が固定され、透過フィルター６の内部に配置されている。   A support piece 7 is provided above the transmission filter 6, and the support piece 7 is detachably fixed to the main body frame 2.

Then, the titanium dioxide of the transmission filter 6 is activated by the irradiation of ultraviolet rays, and pollutants such as NOx are efficiently oxidized and removed at normal temperature by the contact reaction with the atmosphere and discharged from the exhaust port 4.

透過フィルター６が酸化生成物の付着・堆積により機能が低下した場合には、蓋部材９を取り外し、透過フィルター６を新しいものと交換することにより、容易に大気汚染物質の除去機能を維持することができる。   When the function of the permeation filter 6 is deteriorated due to the adhesion / deposition of oxidation products, the cover member 9 is removed and the permeation filter 6 is replaced with a new one to easily maintain the air pollutant removal function.
