Description

本発明に係るディストリビュータの洗浄構造は、沈降分離を行う槽と、槽内に直立状態で配設されており、被処理水が導入されるチャンバと、チャンバ内の処理水を槽内に分配供給するディストリビュータと、を備える沈殿槽に設けられ、ディストリビュータを洗浄する洗浄構造であって、槽内の処理水を洗浄液としてディストリビュータの内部に供給する洗浄液ラインと、洗浄液ラインで供給された洗浄液によってディストリビュータの内部を洗浄する洗浄部と、を備える。 The cleaning structure for a distributor according to the present invention is a tank that performs sedimentation separation, is disposed in an upright state in the tank, and a chamber into which treated water is introduced, and the treated water in the chamber is distributed and supplied into the tank. And a distributor configured to wash the distributor, the cleaning liquid line supplying the treated water in the tank as a cleaning liquid to the inside of the distributor, and the cleaning liquid supplied in the cleaning liquid line. A cleaning section for cleaning the inside .

本発明に係るディストリビュータの洗浄構造は、槽内の処理水を洗浄液としてディストリビュータの内部に供給する洗浄液ラインと、洗浄液ラインで供給された洗浄液によってディストリビュータの内部を洗浄する洗浄部とを備えている。このように、槽内の処理水を洗浄液ラインで洗浄液として洗浄部へ供給することによって、槽内の処理水と洗浄液との間の温度差を低減することができるため、槽内での水流の乱れを更に低減することができる。以上によって、ディストリビュータの洗浄中における、処理性能を向上することができる。 Cleaning the structure of the distributor according to the present invention, it includes a cleaning liquid line for supplying the interior of the distributor as a wash solution the treated water in the tank, and a cleaning unit for cleaning the interior of the distributor by the supplied cleaning liquid in the cleaning liquid line Yes. In this way, by supplying the treated water in the tank to the cleaning unit as the cleaning liquid in the cleaning liquid line, the temperature difference between the processed water in the tank and the cleaning liquid can be reduced. Disturbance can be further reduced. As a result, the processing performance during the cleaning of the distributor can be improved.

また、本発明に係るディストリビュータの洗浄構造において、上下方向において、槽内の処理水の水面側の第１の流出口とディストリビュータとの間の位置から、槽内の処理水を取り出す取出部をさらに備え、洗浄液ラインは、洗浄部と取出部とに接続され、取出部は、槽の側面に設けられた第２の流出口によって構成されていてよい。これによって、槽内の処理水を容易に取り出すことが可能となる。また、取出部は、上下方向において、処理水の水面側の第１の流出口とディストリビュータとの間の位置から、槽内の処理水を取り出すことによって、槽内で洗浄液による上昇流の増加を抑制することができる。 Further, in the distributor cleaning structure according to the present invention, in the up and down direction, there is further provided an extraction portion for taking out the treated water in the tank from a position between the first outlet on the water surface side of the treated water in the tank and the distributor. The cleaning liquid line may be connected to the cleaning section and the extraction section, and the extraction section may be constituted by a second outlet provided on the side surface of the tank. As a result, the treated water in the tank can be easily taken out. In addition, in the vertical direction, the take-out part increases the upward flow due to the cleaning liquid in the tank by taking out the treated water in the tank from the position between the first outlet on the water surface side of the treated water and the distributor. Can be suppressed.

また、本発明に係るディストリビュータの洗浄構造において、上下方向において、槽内の処理水の水面側の第１の流出口と前記ディストリビュータとの間の位置から、槽内の処理水を取り出す取出部をさらに備え、洗浄液ラインは、洗浄部と取出部とに接続され、取出部は、槽内に配置されるポンプによって構成されていてよい。これによって、ポンプの位置を変更することで容易に洗浄液の取り出し位置を変更することが可能となる。また、取出部は、上下方向において、処理水の水面側の第１の流出口とディストリビュータとの間の位置から、槽内の処理水を取り出すことによって、槽内で洗浄液による上昇流の増加を抑制することができる。 Further, in the distributor cleaning structure according to the present invention, in the vertical direction, an outlet for taking out the treated water in the tank from the position between the first outlet on the water surface side of the treated water in the tank and the distributor is provided. Further, the cleaning liquid line may be connected to the cleaning unit and the extraction unit, and the extraction unit may be configured by a pump disposed in the tank. Accordingly, it is possible to easily change the position for taking out the cleaning liquid by changing the position of the pump. In addition, in the vertical direction, the take-out part increases the upward flow due to the cleaning liquid in the tank by taking out the treated water in the tank from the position between the first outlet on the water surface side of the treated water and the distributor. Can be suppressed.
