【考案の詳細な説明】
この考案は、汚水浄化装置としての三相流動層
接触酸化装置に関するものである。[Detailed Description of the Invention] This invention relates to a three-phase fluidized bed catalytic oxidation device as a sewage purification device.
この種の装置は、縦型通水塔内に上昇流による
流動層が設けられ、この流動層の上下を区画する
ネツトが設けられている。 In this type of device, a vertical water tower is provided with a fluidized bed caused by upward flow, and a net is provided to separate the upper and lower parts of this fluidized bed.
而してこのネツトの下面には塔底部からの曝気
用気泡が集結して空気層が形成され（空気のホー
ルドアツプ現象）易く、この結果曝気効率が低下
することは勿論上向流が阻止されて流動層内の担
体の運動が不均一になる他上部ネットにおいては
処理水の流出が断続するので塔壁又はネツト自身
に汚水中の固形物が付着し易くなるという欠点が
あつた。 Aeration bubbles from the bottom of the column tend to gather on the bottom surface of this net to form an air layer (air hold-up phenomenon), which not only reduces the aeration efficiency but also blocks the upward flow. In addition, the movement of the carriers in the fluidized bed becomes uneven, and the outflow of the treated water in the upper net is intermittent, making it easy for solids in the sewage to adhere to the tower wall or the net itself.
本案はこのような不都合を解消する装置を提供
するものであつて、上下の各ネツトの下面を夫々
大気に開放するための通気管を設けたものであ
る。 The present invention provides a device that eliminates these inconveniences, and is provided with ventilation pipes for opening the bottom surfaces of the upper and lower nets to the atmosphere.
この通気管の直径はネツトの目巾より大きいこ
とが好ましいことは勿論であるがその取付方は任
意であり、通常は図の如く一端を大気に開放した
直管をネツトを貫通して設けることによつて容易
に構成される。 It is of course preferable that the diameter of this ventilation pipe be larger than the width of the net, but the installation method is arbitrary, and usually a straight pipe with one end open to the atmosphere is provided penetrating the net as shown in the figure. easily configured by
これによつて各ネツト下面に形成され滞留しよ
うとする空気塊は大きく生長しないうちに管端か
ら大気に放出されるのでネツト下面に空気のホー
ルドアツプを生ぜず接触流動層の上向流と処理水
の円滑な排水が確保されスラツジの付着も防止さ
れるのである。 As a result, air particles that are formed on the bottom surface of each net and tend to stay there are released into the atmosphere from the pipe end before they grow large, so air is not held up on the bottom surface of the net and is treated as an upward flow in the contact fluidized bed. This ensures smooth drainage of water and prevents sludge from sticking.

位置して開口されている。 An embodiment of the present device is shown in the figure, where 1 is a water tower, 2 is a fluidized bed section, and 3 and 4 are upper and lower nets, respectively. 5 is a waste water injection pipe, 6 is an aeration device such as a porous aeration plate, 7 is a treated water overflow port, and 8 is a cover. Reference numerals 9 and 10 are ventilation pipes for releasing bubbles, and upper ends 9a and 10a are open to the atmosphere, respectively, and lower ends 9b and 10b are opened directly below the net 3 or 4.
曝気用気体は下部ネツト下方から散気され小気
泡として上昇するが一部は融合粗大化して夫々の
ネツト下面を揺動するうち下端９ｂ又は１０ｂに
おいて通気管内に吸入され大気に放出される。 The aeration gas is diffused from below the lower net and rises as small bubbles, but a portion of the gas coalesces into coarse bubbles and swings on the lower surface of each net, being sucked into the ventilation pipe at the lower end 9b or 10b and released into the atmosphere.
