Description

本発明は光触媒反応装置に関するものであり、更に詳しくは、光触媒反応を誘発する光源とそれに反応する光触媒反応器を具備して殺菌、消毒及び悪臭の除去を行うように構成された光触媒反応装置に関するものである。   The present invention relates to a photocatalytic reaction device, and more particularly, to a photocatalytic reaction device that includes a light source that induces a photocatalytic reaction and a photocatalytic reactor that reacts with the light source, and is configured to sterilize, disinfect, and remove bad odors. Is.

光触媒とは触媒の一つであって、触媒反応が光エネルギーを受けて起こることをいう。殺菌、消毒及び悪臭の除去を行うように構成された光触媒反応装置には、通常光触媒として二酸化チタン（ＴｉＯ２）が多く使用されており、光源としては紫外線（ＵＶ）光源多く使用されている。 A photocatalyst is one of the catalysts and means that a catalytic reaction takes place upon receiving light energy. In a photocatalytic reaction apparatus configured to sterilize, disinfect, and remove bad odor, titanium dioxide (TiO 2 ) is usually used as a photocatalyst, and an ultraviolet (UV) light source is often used as a light source.

光源の光エネルギーが光触媒に伝達されて光触媒反応が起こると、強い殺菌力を有する酸化物が発生して殺菌、消毒及び悪臭の除去が可能となる。よって、このような光触媒反応装置内で光触媒反応が起こる状態で汚染物質を含む 水や空気を注入すると殺菌、消毒及び悪臭除去の効果が得られる。   When the light energy of the light source is transmitted to the photocatalyst and a photocatalytic reaction occurs, an oxide having a strong sterilizing power is generated, so that sterilization, disinfection, and removal of malodor can be performed. Therefore, when water or air containing a pollutant is injected in a state in which a photocatalytic reaction occurs in such a photocatalytic reaction device, effects of sterilization, disinfection, and malodor removal can be obtained.

特許文献１（以下、「従来技術」と称する）には、このような光触媒反応装置が開示されている。従来技術による光触媒反応装置は、石英管で形成されて光触媒が充填された上昇管２１、前記上昇管２１の下端部に具備された多孔性分散板２３、前記多孔性分散板２３の最末端に具備された反応気体注入部２８、前記上昇管２１の上端部位と連結されたサイクロン２６、前記サイクロン２６の下端部に具備された下降管２５、前記多孔性分散板２３に連結され、前記下降管２５の末端に具備されたループ−シール状の再循環設備、前記サイクロン２６及び上昇管２１の最上端部に具備された反応気体排出部２７及び前記上昇管２１の外部に具備された紫外線ランプ２２を含む。   Patent Document 1 (hereinafter referred to as “prior art”) discloses such a photocatalytic reaction device. A conventional photocatalytic reaction apparatus includes a riser tube 21 formed of a quartz tube and filled with a photocatalyst, a porous dispersion plate 23 provided at the lower end of the riser tube 21, and the extreme end of the porous dispersion plate 23. The reaction gas injection part 28 provided, the cyclone 26 connected to the upper end part of the riser 21, the downcomer pipe 25 provided at the lower end part of the cyclone 26, and the downcomer pipe connected to the porous dispersion plate 23. A loop-seal recirculation facility provided at the end of 25, a reaction gas discharge unit 27 provided at the uppermost end of the cyclone 26 and the rising pipe 21, and an ultraviolet lamp 22 provided outside the rising pipe 21. including.

しかし、従来技術に光触媒反応装置は上昇管２１の内部に光触媒が充填されるため殺菌、消毒能力に比べ光触媒装置に必要な光触媒剤の量が多くなり、光触媒剤が反応気体と一緒に循環するため殺菌消毒能力が均一ではなくなる可能性がある問題点があった。   However, since the photocatalytic reaction device in the prior art is filled with the photocatalyst inside the ascending pipe 21, the amount of the photocatalytic agent required for the photocatalytic device is larger than the sterilization and disinfection ability, and the photocatalytic agent circulates together with the reaction gas. Therefore, there is a problem that the disinfection ability may not be uniform.

以下では、添付した図面を参照して本発明による光触媒反応装置の好ましい実施例を詳細に説明する。   Hereinafter, preferred embodiments of a photocatalytic reaction device according to the present invention will be described in detail with reference to the accompanying drawings.

図１は本発明の第１実施例による光触媒反応装置の正面を示す部分断面図であり、図２は本発明の第１実施例による光触媒反応装置の側面を示す部分断面図である。   FIG. 1 is a partial sectional view showing the front of the photocatalytic reaction device according to the first embodiment of the present invention, and FIG. 2 is a partial sectional view showing the side of the photocatalytic reaction device according to the first embodiment of the present invention.

図１及び図２を参照すると、本発明による光触媒反応装置は上部ハウジング３０と下部ハウジング２０を含む。   Referring to FIGS. 1 and 2, the photocatalytic reactor according to the present invention includes an upper housing 30 and a lower housing 20.

上部ハウジング３０と下部ハウジング２０は、光が透過するようにガラス材質を選択することが好ましい。上部ハウジング３０と下部ハウジング２０は全体的におおよそ円筒状を有する。下部ハウジング２０の上部は上部ハウジング３０より直径が大きい。それゆえに、上部ハウジング３０が下部ハウジング２０の内部に差し込まれるように設置される。このように差し込まれた状態で固定されるように上部ハウジング３０と下部ハウジング２０の両側面には密着手段５が設置される。   The upper housing 30 and the lower housing 20 are preferably selected from glass materials so that light can pass therethrough. The upper housing 30 and the lower housing 20 have a generally cylindrical shape as a whole. The upper part of the lower housing 20 is larger in diameter than the upper housing 30. Therefore, the upper housing 30 is installed so as to be inserted into the lower housing 20. The contact means 5 are installed on both side surfaces of the upper housing 30 and the lower housing 20 so as to be fixed in the inserted state.

上部ハウジング３０の外面と下部ハウジング２０の内面との間には反応流路１０が形成され、この反応流路１０の中で光触媒反応が起こる。   A reaction channel 10 is formed between the outer surface of the upper housing 30 and the inner surface of the lower housing 20, and a photocatalytic reaction occurs in the reaction channel 10.

図３及び図４は本発明の第１実施例による光触媒反応装置の下部ハウジング２０を示す部分断面図であって、図３は正面を、図４は側面を示す図である。図５は本発明の第１実施例による光触媒反応装置の下部ハウジング２０を示す断面図であって、図３のＡ−Ａ線に沿ったものである。   3 and 4 are partial sectional views showing the lower housing 20 of the photocatalytic reaction device according to the first embodiment of the present invention. FIG. 3 is a front view, and FIG. 4 is a side view. FIG. 5 is a sectional view showing the lower housing 20 of the photocatalytic reaction device according to the first embodiment of the present invention, and is taken along the line AA of FIG.

図３乃至図５を参照すると、本発明による光触媒反応装置の下部ハウジング２０には上部に下側密着部２５が形成される。下側密着部２５は上部ハウジング３０と密着される部位であって、上側に行くほど直径が広くなるように形成される。下側密着部２５の上端には挿入口２７が形成され、上部ハウジング３０がこの挿入口２７を介して下部ハウジング２０の内部に挿入される。
下側密着部２５の下には下部ハウジング２０の両側面に下側かかり部２６が形成される。下側かかり部２６には下部ハウジング２０の外側に突出されて上部ハウジング３０と下部ハウジング２０を固定する密着手段５の下端が下側かかり部２６にかかるようになる。それによって上部ハウジング３０の外面と下部ハウジング２０の内面が密着するようになり、その間にある流路の気密が維持される。 Referring to FIGS. 3 to 5, a lower contact portion 25 is formed at the upper portion of the lower housing 20 of the photocatalytic reaction device according to the present invention. The lower contact portion 25 is a portion that is in close contact with the upper housing 30 and is formed so that the diameter increases toward the upper side. An insertion port 27 is formed at the upper end of the lower contact portion 25, and the upper housing 30 is inserted into the lower housing 20 through the insertion port 27.
Under the lower contact portion 25, lower hook portions 26 are formed on both side surfaces of the lower housing 20. The lower hooking portion 26 protrudes to the outside of the lower housing 20 so that the lower end of the contact means 5 that fixes the upper housing 30 and the lower housing 20 is hooked on the lower hooking portion 26. As a result, the outer surface of the upper housing 30 and the inner surface of the lower housing 20 come into close contact with each other, and the airtightness of the channel between them is maintained.

The injection port 22 has a long pipe shape and is formed integrally with the injection portion 21. Contaminated fluid flows into the lower housing 20 through the inlet 22. A recess 24 is formed between the injection part 21 and the reaction part 23. The recess 24 is formed along the peripheral edge of the side wall so that the side wall of the lower housing 20 is recessed inward.

注入部２１の下部には排水口２９が設けられ、この排水口２９に排水弁２８が設置される。排水口２９は反応によって発生した水又はその他の液体を外部に排出するためのものである。注入部２１の下側に液体を溜めてから排水弁２８を開けて一時に排出するように構成される。排水口２９は注入部２１の下側に延長され、注入部２１と一体に形成される。   A drainage port 29 is provided in the lower part of the injection part 21, and a drainage valve 28 is installed in the drainage port 29.

図６及び図７は本発明の第１実施例による光触媒反応装置の上部ハウジング３０を示す部分断面図であって、図６は正面を、図７は側面を示す図である。   6 and 7 are partial sectional views showing the upper housing 30 of the photocatalytic reaction device according to the first embodiment of the present invention. FIG. 6 is a front view and FIG. 7 is a side view.

図６及び図７を参照すると、本発明による光触媒反応装置は下部に光源保護部３１が形成される。   Referring to FIGS. 6 and 7, the photocatalytic reaction device according to the present invention has a light source protection part 31 formed at the bottom.

光源保護部３１の下部は塞がっており、外形は円筒状を成す。内部には光源が設置されるように円筒状の空間が形成される。光源保護部３１は紫外線が通過するようにガラスや石英材質を使用してもよい。
光源保護部３１の上側は紫外線光源１が光源保護部３１の内部に入るように開口３７が形成され、上側に行くほど直径が広くなるように形成されて容易に紫外線光源１を設置されるように形成される。光源保護部３１の上部側面には上側かかり部３９が形成される。上側かかり部２９には密着手段５の上端がかかり、下側かかり部２６には密着手段５の下端がかかって密着手段５の張力によって上部ハウジング３０と下部ハウジング２０が密着する。 The lower part of the light source protection part 31 is closed and the outer shape is cylindrical. A cylindrical space is formed in the interior so that a light source is installed. The light source protection unit 31 may use glass or quartz material so that ultraviolet rays can pass through.
An opening 37 is formed on the upper side of the light source protection unit 31 so that the ultraviolet light source 1 enters the inside of the light source protection unit 31, and the diameter increases toward the upper side so that the ultraviolet light source 1 can be easily installed. Formed. An upper hook 39 is formed on the upper side surface of the light source protection part 31. The upper engagement portion 29 is applied to the upper end of the contact means 5, and the lower engagement portion 26 is applied to the lower end of the contact means 5, so that the upper housing 30 and the lower housing 20 are in close contact with each other due to the tension of the contact means 5.

光源保護部３１の上部外側にはスカート部３３が形成される。光源保護部３１の外面から突出されて下側に延長されるスカート部３３の内部には排出流路３４が形成される。排出流路３４はスカート部３３の内面と光源保護部３１の外面との間に形成される。スカート部３３の一側面には外側に排出口３５が形成されて排出流路３４と連結される。よって、排出流路３４に入った流体が排出口３５から出るように形成される。   A skirt portion 33 is formed on the upper outer side of the light source protection portion 31. A discharge channel 34 is formed inside the skirt portion 33 that protrudes from the outer surface of the light source protection portion 31 and extends downward. The discharge channel 34 is formed between the inner surface of the skirt portion 33 and the outer surface of the light source protection portion 31. A discharge port 35 is formed on one side of the skirt portion 33 and connected to the discharge channel 34. Therefore, the fluid entering the discharge channel 34 is formed so as to exit from the discharge port 35.

図１乃至図７を参照すると、本発明による光触媒反応装置は下部ハウジングの挿入口２７に上部ハウジング３０の光源保護部３１が挿入設置される。この状態で密着手段５を上側かかり部３９と下側かかり部２６に設置すると、上部ハウジング３０と下部ハウジング２０が密着する。   1 to 7, in the photocatalytic reaction device according to the present invention, the light source protection part 31 of the upper housing 30 is inserted and installed in the insertion port 27 of the lower housing. In this state, when the contact means 5 is installed on the upper hook portion 39 and the lower hook portion 26, the upper housing 30 and the lower housing 20 are in close contact with each other.

また、図２及び図１４に示したように、下部ハウジング２０の反応部２３の内面には支持台７と光触媒が塗布された不織布６が設置される。不織布６は円筒状に形成され、不織布６にスプレー型の光触媒を塗布して光触媒が不織布６の組織の間にもれなく分布されるようにする。支持台７は金属材質で形成され、不織布６を堅固に支持するためのものである。支持台７は不織布６より直径が微細に大きく、不織布６の外面が支持台７に接着固定される。   As shown in FIGS. 2 and 14, the support 7 and the nonwoven fabric 6 coated with the photocatalyst are installed on the inner surface of the reaction portion 23 of the lower housing 20. The non-woven fabric 6 is formed in a cylindrical shape, and a spray-type photocatalyst is applied to the non-woven fabric 6 so that the photocatalyst is distributed between the tissues of the non-woven fabric 6. The support base 7 is made of a metal material and is used for firmly supporting the nonwoven fabric 6. The support base 7 has a finer diameter than the nonwoven fabric 6, and the outer surface of the nonwoven fabric 6 is bonded and fixed to the support base 7.

このように、不織布６と支持台７が設置された反応部２３の内側面と光源保護部３１の外面との間には流体が流通される反応流路１０が形成される。この反応流路１０は上部の排出流路３４と連通され、下部の注入部２１と連通される。よって、注入口２２を介して注入部２１に汚染された反応流体が入ってくると、反応流路１０と排出流路３４を通過し、排出口３５を介して外部に排出される。   Thus, the reaction flow path 10 through which the fluid flows is formed between the inner surface of the reaction unit 23 where the nonwoven fabric 6 and the support base 7 are installed and the outer surface of the light source protection unit 31. The reaction channel 10 communicates with the upper discharge channel 34 and communicates with the lower injection part 21. Therefore, when the contaminated reaction fluid enters the injection part 21 through the injection port 22, it passes through the reaction channel 10 and the discharge channel 34 and is discharged to the outside through the discharge port 35.

紫外線光源１を作動し、反応流体を汚染物質を含む空気（水分を含む）にして注入口２２を介して注入すると、反応流路１０の内部で光触媒反応が起こって殺菌、消毒、悪臭の除去が行われ、排出口３５から浄化された空気が排出される。   When the ultraviolet light source 1 is activated and the reaction fluid is made into polluted air (including moisture) and injected through the inlet 22, a photocatalytic reaction takes place inside the reaction channel 10 to sterilize, disinfect, and remove odors. The purified air is discharged from the discharge port 35.

この際、注入部２１、反応流路１０は垂直に形成される一方、注入口２２は水平に形成される。よって、注入口２２は注入部２１及び反応流路１０と直交に配置されるため反応流体に乱流が形成される。このように乱流が形成された状態で凹部２４を通過しながら更に乱流が強くなり、この状態で不織布６周辺を通過するため、層流が完全に乱流に変化する。反応流体は反応流路１０を通過しながら光触媒反応によって殺菌、消毒、悪臭の除去が行われるが、反応流路１０内部で反応流体が完全に乱流になるため、反応物と光触媒との接触確率が増加し、それによって不織布６の表面に塗布された光触媒との反応が層流である場合より活性化される。また、光源保護部３１と反応部２３との間の狭い空間に反応流路１０が形成されるため、不織布６を成す繊維の間に反応流体が浸透して接触面積が増加し、それによって反応装置の性能が向上される。   At this time, the injection part 21 and the reaction channel 10 are formed vertically, while the injection port 22 is formed horizontally. Therefore, since the inlet 22 is arranged orthogonal to the injection part 21 and the reaction flow path 10, a turbulent flow is formed in the reaction fluid. In such a state where turbulent flow is formed, the turbulent flow is further strengthened while passing through the recess 24, and in this state, the turbulent flow passes through the periphery of the non-woven fabric 6, so that the laminar flow completely changes to turbulent flow. While the reaction fluid passes through the reaction channel 10 and is sterilized, disinfected, and odor is removed by the photocatalytic reaction, the reaction fluid becomes completely turbulent in the reaction channel 10, so that the reaction product is in contact with the photocatalyst The probability is increased, whereby the reaction with the photocatalyst applied to the surface of the nonwoven fabric 6 is more activated than when it is laminar. Moreover, since the reaction flow path 10 is formed in the narrow space between the light source protection part 31 and the reaction part 23, the reaction fluid permeates between the fibers forming the nonwoven fabric 6 to increase the contact area, thereby causing the reaction. The performance of the device is improved.

図８は、本発明の第２実施例による光触媒反応装置の下部ハウジング２０を示す正面図である。図９は、本発明の第２実施例による光触媒反応装置の下部ハウジング２０を示す側面図である。図１０は、本発明の第２実施例による光触媒反応装置の下部ハウジング２０を示す断面図であって、図８のＢ−Ｂ線に沿ったものである。   FIG. 8 is a front view showing the lower housing 20 of the photocatalytic reaction device according to the second embodiment of the present invention. FIG. 9 is a side view showing the lower housing 20 of the photocatalytic reaction device according to the second embodiment of the present invention. FIG. 10 is a cross-sectional view of the lower housing 20 of the photocatalytic reaction device according to the second embodiment of the present invention, taken along the line BB of FIG.

図８乃至図１０を参照すると、本発明の第２実施例による光触媒反応装置の下部ハウジング２０は注入口４１が注入部２１と第１実施例のように直交するのではなく、注入口４１が下側に傾斜して形成され、注入口４１の中心軸と注入部２１の中心軸が直交せずに離隔するように形成される。よって、注入口４１を介して注入される反応流体は螺旋形の経路を成して上側に進行する。反応流体が上側方向に進行するようになるため、反応流体が注入口４１及び反応部２３に進入する速度が増加する。また、反応流体の経路が螺旋形を成すため、遠心力によって外側の不織布６の方に圧力を受けるようになって乱流形成が更に容易である。よって、光触媒反応装置の効率が向上される。   8 to 10, in the lower housing 20 of the photocatalytic reaction device according to the second embodiment of the present invention, the injection port 41 is not orthogonal to the injection portion 21 as in the first embodiment. It is formed so as to be inclined downward, so that the central axis of the injection port 41 and the central axis of the injection part 21 are separated from each other without being orthogonal to each other. Therefore, the reaction fluid injected through the injection port 41 proceeds upward through a spiral path. Since the reaction fluid proceeds upward, the speed at which the reaction fluid enters the inlet 41 and the reaction unit 23 increases. Moreover, since the path of the reaction fluid has a spiral shape, the outer nonwoven fabric 6 is subjected to pressure by centrifugal force, and turbulent flow formation is further facilitated. Therefore, the efficiency of the photocatalytic reaction device is improved.

図１１は、本発明の第３実施例による光触媒反応装置の下部ハウジング２０を示す正面図である。図１２は、本発明の第３実施例による光触媒反応装置の下部ハウジング２０を示す側面図である。図１３は、本発明の第３実施例による光触媒反応装置の下部ハウジング２０を示す断面図であって、図１１のＣ−Ｃ線に沿ったものである。   FIG. 11 is a front view showing the lower housing 20 of the photocatalytic reaction device according to the third embodiment of the present invention. FIG. 12 is a side view showing the lower housing 20 of the photocatalytic reaction device according to the third embodiment of the present invention. FIG. 13 is a cross-sectional view showing the lower housing 20 of the photocatalytic reaction device according to the third embodiment of the present invention, and is taken along the line CC of FIG.

図１１乃至図１３を参照すると、本発明の第３実施例による光触媒反応装置の下部ハウジング２０には注入部２１に注入口４２，４３が２つ形成される。２つの注入口４２，４３は互いに反対側に平行して形成され、２つの注入口４２，４３の中心軸は注入部２１の中心軸と離隔される。また、２つの注入口４２，４３は注入部２１から下側に傾斜して形成される。よって、２つの注入口４２，４３を介して反応流体が注入部２１に入ってくると、反応流体が注入部２１の内部で混合されて螺旋形の経路に沿って上側に移送され、この過程で反応流体に乱流が形成されて反応流路１０内部での反応効果が向上される。
本発明による光触媒反応装置は、不均一状の光触媒（二酸化チタン、ＴｉＯ２）を不織布６に塗布して反応流路１０の内部に設置し、流体の挙動を反応部２３の内壁の方に最大に誘導すると同時に反応流体を乱流に形成させ、反応流体内の反応物に対する光触媒酸化反応の効率を向上させたものである。
また、円筒状を成す紫外線光源１の外側を囲むように光触媒が塗布された不織布６が設置されるため、紫外線光源１を照査された光触媒の酸化反応が反応部２３全域にわたってむらなく起こる。 Referring to FIGS. 11 to 13, two injection ports 42 and 43 are formed in the injection part 21 in the lower housing 20 of the photocatalytic reaction device according to the third embodiment of the present invention. The two inlets 42 and 43 are formed in parallel with each other on the opposite side, and the central axes of the two inlets 42 and 43 are separated from the central axis of the injection part 21. Further, the two injection ports 42 and 43 are formed to be inclined downward from the injection portion 21. Therefore, when the reaction fluid enters the injection portion 21 via the two injection ports 42 and 43, the reaction fluid is mixed inside the injection portion 21 and transferred upward along the spiral path. Thus, a turbulent flow is formed in the reaction fluid, and the reaction effect in the reaction channel 10 is improved.
In the photocatalytic reaction device according to the present invention, a heterogeneous photocatalyst (titanium dioxide, TiO 2 ) is applied to the nonwoven fabric 6 and installed inside the reaction flow path 10, and the behavior of the fluid is maximized toward the inner wall of the reaction section 23. At the same time, the reaction fluid is formed into a turbulent flow to improve the efficiency of the photocatalytic oxidation reaction for the reactant in the reaction fluid.
Further, since the non-woven fabric 6 coated with the photocatalyst is disposed so as to surround the outside of the ultraviolet light source 1 having a cylindrical shape, the oxidation reaction of the photocatalyst that has been inspected with the ultraviolet light source 1 occurs uniformly throughout the reaction part 23.

図１５は本発明による光触媒反応装置の反応気体の流用による反応結果を示す比較実験資料であり、図１６は本発明による光触媒反応装置の安定性をテストした結果である。   FIG. 15 is a comparative experimental data showing a reaction result by diverting the reaction gas of the photocatalytic reaction device according to the present invention, and FIG. 16 is a result of testing the stability of the photocatalytic reaction device according to the present invention.

図１５には、Ｘ軸の反応流体の流量によるＹ軸の反応流体内の反応物質の分解率が示されている。図１５において、第１グラフは不織布６ではない一般的な金属材質の滑らかな支持台に光触媒が塗布された場合であり（（１）ＳＴＳ−ｐｌａｉｎ）、第２グラフは不織布６に光触媒が塗布された場合を示すグラフであり（（２）Ｆｅｌｔ−ｐｌａｉｎ）、第３グラフは不織布６に光触媒が塗布された場合であって（（３）Ｆｅｌｔ−ｓｉｎｇｌｅ ｔａｎｇｅｎｔ）、第２実施例による接線方向に注入口４１が形成された光触媒反応装置を適用した場合である。   FIG. 15 shows the decomposition rate of the reactant in the Y-axis reaction fluid according to the flow rate of the X-axis reaction fluid. In FIG. 15, the first graph is a case where a photocatalyst is applied to a smooth support base of a general metal material that is not the nonwoven fabric 6 ((1) STS-plain), and the second graph is a photocatalyst applied to the nonwoven fabric 6. (3) Felt-single tangent, and the third graph shows a case where a photocatalyst is applied to the nonwoven fabric 6 (3) Felt-single tangent. This is a case where a photocatalytic reaction device in which an injection port 41 is formed is applied.

図１５に示したように、流量が増加するほど流体が有する運動エネルギーが増加するため乱流の形成に役に立つ。よって、流量が増加するほど反応性が高くなる。しかし、流路が一定範囲を超えて更に増加する場合にはかえって反応性が減少する。これは、反応流体が反応部２３の内部に留まる時間が減るようになって、反応流体と光触媒が接触する確率が低くなるためである。   As shown in FIG. 15, the kinetic energy of the fluid increases as the flow rate increases, which is useful for the formation of turbulent flow. Therefore, the higher the flow rate, the higher the reactivity. However, when the flow path is further increased beyond a certain range, the reactivity decreases. This is because the time during which the reaction fluid stays in the reaction unit 23 is reduced, and the probability that the reaction fluid and the photocatalyst are reduced is reduced.

この実験を適用した装置にでは、汚染された反応流体を分当たり５リットルで注入したとき最も反応率が高く、それ以上の流量では反応率が減少していた。
また、不織布６に光触媒を適用した第２グラフが不織布６ではない一般的な滑らかな金属に光触媒を塗布適用した第１グラブの場合より反応性が甚だしく高いことが分かり、第１実施例による垂直な注入口２２を提供した場合を示す第２グラフより第２実施例による接線方向に注入される注入口４１を適用した場合を示す第３グラフの反応性が高いことが分かった。 In the apparatus to which this experiment was applied, the reaction rate was highest when contaminated reaction fluid was injected at 5 liters per minute, and the reaction rate was reduced at a flow rate higher than that.
Further, it can be seen that the second graph in which the photocatalyst is applied to the non-woven fabric 6 is much more reactive than the first grab in which the photocatalyst is applied to a general smooth metal that is not the non-woven fabric 6, and the vertical direction according to the first example. From the second graph showing the case where a simple inlet 22 is provided, it was found that the reactivity of the third graph showing the case where the inlet 41 injected in the tangential direction according to the second embodiment is applied is high.

図１６には、本発明の第２実施例による光触媒反応装置を使用した安定性テストの結果を示すグラフが示されている。図１６を参照すると、光触媒反応装置を数日間持続的に稼動しても時間が経つほど反応率が落ちないことが分かる。光触媒を不織布６に噴射塗布するため、光触媒反応装置を長期間使用すると光触媒が不織布６から落ちる確率が高くなる恐れがある。しかし、反応流体の流れが反応部２３の内壁面に沿って上るため、発生するせん断応力は強く凝集されて結合された光触媒粒子を不織布６の外部に落とすには相対的に弱い力であることが分かる。   FIG. 16 is a graph showing the results of a stability test using the photocatalytic reactor according to the second embodiment of the present invention. Referring to FIG. 16, it can be seen that even if the photocatalytic reaction device is continuously operated for several days, the reaction rate does not decrease with time. Since the photocatalyst is spray-coated on the nonwoven fabric 6, there is a risk that the photocatalyst falls from the nonwoven fabric 6 when the photocatalytic reaction device is used for a long time. However, since the flow of the reaction fluid rises along the inner wall surface of the reaction part 23, the generated shear stress is a relatively weak force for dropping the aggregated and bound photocatalyst particles outside the nonwoven fabric 6. I understand.
