Description

本発明は所謂、布製の散気装置に関するものである。  The present invention relates to a so-called cloth diffuser.

従来、下水処理施設や各種産業排水処理施設などにおける曝気槽の水中酸素濃度を向上させるために様々な散気装置が使用されている。中でも比較的微細な気泡を発生させることが可能な散気装置に、合成ゴム製のメンブレン式散気管があるが、これはゴムチューブに多数の小さな切れ目を入れた構造により、また、合成ゴムの一般的特性として、経年劣化によるゴムの硬化により、散気孔の裂けなどの課題があった。  Conventionally, various air diffusers have been used to improve the oxygen concentration in the aeration tank in sewage treatment facilities and various industrial wastewater treatment facilities. Among the diffuser devices that can generate relatively fine bubbles, there is a membrane-type diffuser tube made of synthetic rubber. This is due to the structure of the rubber tube with many small cuts, and the synthetic rubber As a general characteristic, there have been problems such as tearing of diffused pores due to rubber curing due to aging.

特開平2012−257569JP 2012-25769 A

即ち、従来の合成ゴム製のメンブレン式散気管はゴムチューブに多数の小さな切れ目を入れた構造をしており、ゴムチューブ内部に空気を送り込み、チューブ内の内圧が上がると、通常閉じた状態にある小さな切れ目が開くことで空気が通過し、水中に微細な気泡を発生させるが、ゴムチューブに入れた縦長の切れ目の端面にかかる応力により、また、合成ゴムの一般的特性として、経年劣化によるゴムの硬化により、切れ目(散気孔)の裂けなどの課題があった。In other words, the conventional synthetic rubber membrane diffuser has a structure in which a large number of small cuts are made in the rubber tube. When air is fed into the rubber tube and the internal pressure in the tube increases, it normally closes. When a small cut opens, air passes and generates fine bubbles in the water, but due to the stress applied to the end face of the long cut in the rubber tube, and as a general characteristic of synthetic rubber, Due to the hardening of the rubber, there were problems such as tearing of cuts (aeration holes).

本発明は、この従来の課題を解決する手段として、繊維を織物にした布を筒状に縫製し、またはその縦糸か横糸の繊維のどちらかに伸縮自在の繊維を織り込んだことを特徴とする散気装置である。  As a means for solving this conventional problem, the present invention is characterized in that a fabric made of a woven fabric is sewn in a cylindrical shape, or a stretchable fiber is woven into either the warp or weft fiber. A diffuser.

本発明の散気装置は繊維を織物にした布製の散気装置であるため、従来の合成ゴムチューブに多数の小さな切れ目をあけ、そこから微細な空気を発生するメンブレン式の散気管と比べて、ゴムチューブを布に変えたことで、縦横に編み込んだ繊維の隙間からの散気となるため切れ目が存在せず、メンブレン式散気管のように応力集中や経年劣化により切れ目が裂ける恐れが無い。繊維が送気圧の変化に追随して伸縮するが、送気中は繊維間の空隙が広がることでエアを吹き出し、送気を止めると、繊維間の空隙が狭くなり、水中の汚泥の散気管内への逆流が少なく、散気管の目詰まりを防止する効果も発揮する。  Since the air diffuser of the present invention is a cloth air diffuser made of woven fabric, the conventional synthetic rubber tube has many small cuts, and compared with a membrane air diffuser that generates fine air therefrom. By changing the rubber tube into a cloth, there is no break because it diffuses from the gaps in the fibers knitted vertically and horizontally, and there is no risk of tearing due to stress concentration or aging degradation like a membrane diffuser . The fiber expands and contracts following the change in the air pressure, but when air is blown, air is blown out and the air gap is narrowed when the air is stopped. There is little backflow into the tube, and the effect of preventing clogging of the diffuser tube is also exhibited.

次に、本発明を実施するための形態について実施例を図1〜図3ついて説明する。  Next, an embodiment of the present invention will be described with reference to FIGS.

図1、図2、図3において、1は本発明の散気管の支持体で、図2に示すような断面形状になっている。2はこの支持体の外周に挿入した繊維の散気管チューブである。3はこの散気管チューブ2を支持体1の外周に挿入して固定するバンドである。  1, 2, and 3, reference numeral 1 denotes a diffuser tube support according to the present invention, which has a cross-sectional shape as shown in FIG. 2. Reference numeral 2 denotes a fiber diffuser tube inserted on the outer periphery of the support. Reference numeral 3 denotes a band for inserting and fixing the diffuser tube 2 to the outer periphery of the support 1.

図2の散気管支持体の断面図に示す6は空気を送り込む空気通風孔で図のように、散気管チューブ2の内径側に圧力空気を送り込む通風路7に通じている。  2 shown in the cross-sectional view of the bronchial carrier shown in FIG. 2 is an air vent hole for sending air, and communicates with a vent path 7 for sending pressurized air to the inner diameter side of the air diffuser tube 2 as shown in the figure.

図3の断面詳細図で説明すると、散気管支持体1の圧力空気の通路7に送り込まれた空気は繊維の散気管チューブ2の縦糸4と横糸5の間隙から漏れ出て、微細な気泡を水中に放出して散気を行う。  Referring to the detailed cross-sectional view of FIG. 3, the air fed into the pressure air passage 7 of the bronchial carrier 1 leaks from the gap between the warp 4 and the weft 5 of the fiber diffusing tube 2 and forms fine bubbles. Discharge into water for aeration.

次に、繊維の散気管チューブ2の横糸5を伸縮性の横糸にすると、送気された圧力空気は繊維の散気管の横糸5は伸びて、円周方向に膨らみ、横糸5と縦糸4の空隙が広がり、細泡を水中にスムーズに放出する。また、送気を止めると、横糸5は縮み水中の汚泥の逆流を防止する作用をする。
このように、例えば、横糸5を伸縮性の繊維にすることにより、ゴム製の散気管のように切れ目を入れた構造と比較し、細孔の破れの恐れが無く、伸縮自在の繊維が送気圧の変化に追随して伸縮するために、散気泡の制御が容易で、送気中は繊維間の空隙が広がり、送気を止めると、繊維間の空隙が狭くなり、したがって、水中の汚泥の逆流が少なく、散気管の目詰まりが発生しないという効果を発揮する。
Next, when the weft yarn 5 of the fiber aeration tube 2 is made into a stretchable weft, the sent air is stretched in the weft 5 of the fiber aeration tube and swells in the circumferential direction, and the weft 5 and warp 4 The air gap expands and fine bubbles are released smoothly into the water. When the air supply is stopped, the weft 5 shrinks and acts to prevent the backflow of sludge in the water.
Thus, for example, by making the weft thread 5 into a stretchable fiber, there is no risk of pore breakage compared to a structure with a cut like a rubber aeration tube, and the stretchable fiber is fed. Since the expansion and contraction follows the change in the atmospheric pressure, it is easy to control the air bubbles, and the air gap between the fibers widens during air supply. There is little back flow, and the effect is that the clogging of the diffuser tube does not occur.

本発明は合成繊維の織物をチューブ状にして、散気管を形成しているが、円盤状に繊維の織物を裁断して、円盤状の散気管にすることもできる。
また、本発明は水中の汚泥の浄化を目的とした散気管であるが、たとえば、空気を送り込むと好都合な食品の加工工程などに応用できる。
In the present invention, a synthetic fiber fabric is formed into a tube shape to form an air diffuser tube. However, the fiber fabric may be cut into a disk shape to form a disk-shaped air diffuser tube.
In addition, the present invention is an air diffuser for the purpose of purifying sludge in water, but can be applied to, for example, a food processing process that is convenient when air is fed.

Among the diffuser devices that can generate relatively fine bubbles, there is a membrane-type diffuser tube made of synthetic rubber. This is due to the structure of the rubber tube with many small cuts, and the synthetic rubber As a characteristic, there was a problem of rupture of diffused holes due to rubber curing due to aging.

即ち、従来の合成ゴム製のメンブレン式散気管はゴムチューブに多数の小さな切れ目を入れた構造をしており、ゴムチューブ内部に空気を送り込み、チューブ内の内圧が上がると、通常閉じた状態にある小さな切れ目が開くことで空気が通過し、水中に微細な気泡を発生させるが、ゴムチューブに入れた縦長の切れ目の端面にかかる応力により、また、合成ゴムの一般的特性として、経年劣化によるゴムの硬化により、切れ目(散気孔)の裂けの課題があった。 In other words, the conventional synthetic rubber membrane diffuser has a structure in which a large number of small cuts are made in the rubber tube. When air is fed into the rubber tube and the internal pressure in the tube increases, it normally closes. When a small cut opens, air passes and generates fine bubbles in the water, but due to the stress applied to the end face of the long cut in the rubber tube, and as a general characteristic of synthetic rubber, Due to the hardening of the rubber, there was a problem of tearing of cuts (aeration holes) .

本発明は、この従来の課題を解決する手段として、繊維を織物にした布を筒状に縫製し、またその縦糸か横糸の繊維のどちらかに伸縮自在の繊維を織り込んだことを特徴とする散気装置である。 As a means for solving this conventional problem, the present invention is characterized in that a fabric in which fibers are woven is sewn in a cylindrical shape, and stretchable fibers are woven into either warp or weft fibers. A diffuser.

本発明の散気装置は繊維を織物にした布製の散気装置であるため、従来の合成ゴムチューブに多数の小さな切れ目をあけ、そこから微細な空気を発生するメンブレン式の散気管と比べて、ゴムチューブを布に変えたことで、縦横に編み込んだ繊維の隙間からの散気となるため切れ目が存在せず、メンブレン式散気管のように応力集中や経年劣化により切れ目が裂ける恐れが無い。繊維が送気圧の変化に追随して伸縮するが、送気中は繊維間の空隙が広がることでエアを吹き出し、送気を止めると、繊維間の空隙が狭くなり、水中の汚泥の散気管内への逆流が少なく、散気管の目詰まりを防止する効果も発揮する。  Since the air diffuser of the present invention is a cloth air diffuser made of woven fabric, the conventional synthetic rubber tube has many small cuts, and compared with a membrane air diffuser that generates fine air therefrom. By changing the rubber tube into a cloth, there will be no breaks due to the diffusion of gaps between the fibers weaved vertically and horizontally, and there is no risk of tearing due to stress concentration and aging degradation like membrane-type diffuser tubes . The fiber expands and contracts following the change in the air pressure, but when air is blown, air is blown out and the air gap is narrowed when the air is stopped. There is little backflow into the tube, and the effect of preventing clogging of the diffuser tube is also exhibited.

次に、本発明を実施するための形態について実施例を図1〜図3ついて説明する。  Next, an embodiment of the present invention will be described with reference to FIGS.

図1、図2、図3において、1は本発明の散気管の支持体で、図2に示すような断面形状になっている。2はこの支持体の外周に挿入した繊維の散気管チューブである。3はこの散気管チューブ2を支持体1の外周に挿入して固定するバンドである。  1, 2, and 3, reference numeral 1 denotes a diffuser tube support according to the present invention, which has a cross-sectional shape as shown in FIG. 2. Reference numeral 2 denotes a fiber diffuser tube inserted on the outer periphery of the support. Reference numeral 3 denotes a band for inserting and fixing the diffuser tube 2 to the outer periphery of the support 1.

図2の散気管支持体の断面図に示す6は空気を送り込む空気通風孔で図のように、散気管チューブ2の内径側に圧力空気を送り込む通風路7に通じている。  2 shown in the cross-sectional view of the bronchial carrier shown in FIG. 2 is an air vent hole for sending air, and communicates with a vent path 7 for sending pressurized air to the inner diameter side of the air diffuser tube 2 as shown in the figure.

3の断面詳細図で説明すると、散気管支持体1の圧力空気の通路7に送り込まれた空気は繊維の散気管チューブ2の縦糸4と横糸5の間隙から漏れ出て、微細な気泡を水中に放出して散気を行う。  3, the air sent into the pressure air passage 7 of the bronchial carrier 1 leaks from the gap between the warp 4 and the weft 5 of the fiber diffusing tube 2, and fine bubbles are submerged in the water. Discharge to release.

次に、繊維の散気管チューブ2の横糸5を伸縮性の横糸にすると、送気された圧力空気は繊維の散気管の横糸5は伸びて、円周方向に膨らみ、横糸5と縦糸4の空隙が広がり、細泡を水中にスムーズに放出する。また、送気を止めると、横糸5は縮み水中の汚泥の逆流を防止する作用をする。横糸5を伸縮性の繊維にすることにより、ゴム製の散気管のように切れ目を入れた構造と比較し、細孔の破れの恐れが無く、伸縮自在の繊維が送気圧の変化に追随して伸縮するために、散気泡の制御が容易で、送気中は繊維間の空隙が広がり、送気を止めると、繊維間の空隙が狭くなり、したがって、水中の汚泥の逆流が少なく、散気管の目詰まりが発生しないという効果を発揮する。 Next, when the weft yarn 5 of the fiber aeration tube 2 is made into a stretchable weft, the sent air is stretched in the weft 5 of the fiber aeration tube and swells in the circumferential direction, and the weft 5 and warp 4 The air gap expands and fine bubbles are released smoothly into the water. When the air supply is stopped, the weft 5 shrinks and acts to prevent the backflow of sludge in the water. By making the weft thread 5 into a stretchable fiber, there is no risk of pore breakage compared to a structure with a cut like a rubber diffuser tube, and the stretchable fiber follows the change in air pressure. Therefore, air bubbles are easily controlled during air supply, and when air supply is stopped, the air gaps between fibers are narrowed. It is effective in preventing clogging of the trachea.

本発明は合成繊維の織物をチューブ状にして、散気管を形成しているが、円盤状に繊維の織物を裁断して、円盤状の散気管にすることもできる。また、本発明は水中の汚泥の浄化を目的とした散気管であるが、たとえば、空気を送り込むと好都合な食品の加工工程に応用できる。 In the present invention, a synthetic fiber fabric is formed into a tube shape to form an air diffuser tube. However, the fiber fabric may be cut into a disk shape to form a disk-shaped air diffuser tube. In addition, the present invention is an air diffuser for the purpose of purifying sludge in water. For example, it can be applied to a food processing process that is convenient when air is fed.
