Description

本発明は、汚水処理槽における散気装置に関するものである。   The present invention relates to an air diffuser in a sewage treatment tank.

本発明者は長年、汚水処理槽に設置する汚水処理のための散気装置を研究し、次の新技術を実施化して来た。   For many years, the present inventor has studied a diffuser for sewage treatment installed in a sewage treatment tank and has implemented the following new technology.

しかし、従来の散気管は気泡が細かく酸素効率が良くても、目詰まりが起り易い欠点があり、またディフューザー型は目詰まりは起さないが、気泡が粗すぎるため酸素効率が低下する欠点があった。   However, the conventional air diffuser has the disadvantage that clogging is likely to occur even if the bubbles are fine and the oxygen efficiency is good, and the diffuser type does not cause clogging, but the bubble is too coarse and the oxygen efficiency is reduced. there were.

そこで、本発明は、従来技術に見られる前記のような欠点を一掃するとともに、気泡が細かく酸素効率がよくかつ目詰まりを起さないダブル効果を発揮する画期的な散気装置を提供することを目的とするものである。   Therefore, the present invention provides an epoch-making air diffuser that eliminates the above-mentioned drawbacks found in the prior art and that exhibits a double effect that has fine bubbles and high oxygen efficiency and does not cause clogging. It is for the purpose.

本発明は、多孔質筒体の底面部を基台の上面周囲に設けたパッキングに接地し、このパッキングには適当間隔をおいて設けた薄壁の中心部に強制開口する扉部を形成する縦切れ目を設け、前記多孔質筒体の中心部に送風機に通ずる送気管に送気孔を設けるとともに逆止弁を設け、前記送気管と一体に成る支柱の上端部を前記多孔質筒体に着脱し得るように取付けて成るものである。   In the present invention, the bottom surface portion of the porous cylinder is grounded to a packing provided around the upper surface of the base, and a door portion forcibly opening the center portion of a thin wall provided at an appropriate interval is formed in this packing. A vertical cut is provided, an air supply hole is provided in the air supply pipe that communicates with the blower at the center of the porous cylinder, a check valve is provided, and the upper end of the column that is integral with the air supply pipe is attached to and detached from the porous cylinder. It is attached so that it can be done.

多孔質筒体から発生する微細気泡と，それに対するパッキング部の縦切れ目からの強制送風によって起る左右扉部の開口による粗目気泡が起す撹拌によって、汚水処理槽内部においては酸素供給が円滑に行われるとともに目詰まりを起さないという極めて良好な効果をあげることができ、これによって従来の技術的課題を解決することができる。   Oxygen can be supplied smoothly inside the sewage treatment tank by the fine bubbles generated from the porous cylinder and the agitation caused by the coarse bubbles due to the opening of the left and right doors caused by forced air blowing from the vertical cuts of the packing section. In addition, a very good effect of not causing clogging can be obtained, thereby solving the conventional technical problem.

汚水処理槽に設置した本装置においては、送風機から送風された空気が、送気管の内部にあるボールを押し上げてその周壁の送風孔から多孔質筒体内部に流出する。その空気は多孔質筒体を通過するが、その時、１ｍｍ位の微細気泡となって槽内に散気する。   In the present apparatus installed in the sewage treatment tank, the air blown from the blower pushes up the ball inside the air feed pipe and flows out from the blow hole in the peripheral wall into the porous cylinder. The air passes through the porous cylinder, but at that time, it becomes fine bubbles of about 1 mm and diffuses into the tank.

このような作用が連続して行われることになるが、長時間連続作用がなされると、次第に多孔質筒体に目詰まり現象が起る。散気作用においては、この目詰まり現象は多孔質筒体の上側部分から始まり、散気作用は次第に多孔質筒体の下側部分に移るようになる。   Although such an action is continuously performed, when the continuous action is performed for a long time, a clogging phenomenon gradually occurs in the porous cylinder. In the air diffusion action, this clogging phenomenon starts from the upper part of the porous cylinder, and the air diffusion action gradually moves to the lower part of the porous cylinder.

散気作用が多孔質筒体の下側部分で行われるようになると、それまで閉口状態にあった多孔質筒体に接しているパッキング等に等間隔をおいて設けた縦切れ目のある両扉部が、送風機からの送風によって強制的に外方左右に押し開かれ、汚水槽内に散気するようになる。   When the aeration action is performed at the lower part of the porous cylinder, both doors with vertical cuts provided at equal intervals on the packing, etc. in contact with the porous cylinder that had been closed until then The part is forced to open outward and to the left and right by the air from the blower, and diffuses into the sewage tank.

このパッキングの各縦切れ目部分から発散する空気は微細でなく粗目ではあるが、その上部の多孔質筒体からの散気は中断することがないから、多孔質筒体からの微細な気泡とパッキングの縦切れ目部分からの粗目の気泡が混合した状態になる。これによって、酸素効率の高い微細気泡とこれを撹拌する粗目気泡とによって、汚水処理槽内部に最良な散気作用が行われるようになる。   The air that diverges from each longitudinal cut portion of this packing is not fine but coarse, but the air diffused from the upper porous cylinder is not interrupted, so fine bubbles and packing from the porous cylinder are not interrupted. Coarse air bubbles from the vertical cut portion of the mixture are mixed. As a result, the best aeration action is performed inside the sewage treatment tank by the fine bubbles having high oxygen efficiency and the coarse bubbles that stir the fine bubbles.

送風機が万一停止した時は、送風管内を浮上していた逆止弁が落下して開口部を閉口するから、汚水の逆流浸入は防止される。   In the unlikely event that the blower stops, the check valve that has floated inside the blower pipe falls and closes the opening, so that the backflow of sewage is prevented.

また、多孔質筒体においては、気泡上昇時に、その下部まわりの汚水をマイナス状態で引張る力が作用するため、汚水がパッキングの縦切れ目から吸い込まれるおそれがあるが、パッキング上の縦切れ目は薄い板状の扉部に形成し常時は閉口密着状態にあるから、内部からは送風力によって強制開口しても、外部から汚水の浸入のおそれはない。   In addition, in the porous cylinder, when the bubbles rise, a force that pulls the sewage around the lower part in a negative state acts, so there is a possibility that the sewage may be sucked from the vertical cut of the packing, but the vertical cut on the packing is thin. Since it is formed in a plate-shaped door and is always in close contact with the mouth, there is no risk of entering sewage from the outside even if it is forced to open from the inside by a blowing force.

多孔質筒体の全体が目詰まりを起したり、損傷が起ったときは、多孔質筒体を支持している支柱上の螺子を外して取替えたり、逆止弁の重さを変えたいときは、連結管と送気管との螺合を外して取替えればよい。   If the entire porous cylinder is clogged or damaged, remove the screw on the column that supports the porous cylinder and replace it, or change the weight of the check valve In some cases, the connection pipe and the air supply pipe may be unscrewed and replaced.
