Description

本発明は、工場排水や河川水の水質調査等に適用される非定常液体の濃度計測装置に係り、液体供給手段からの被測定液体（非定常液体）をサンプリング用の容器に採取し、該容器内に採取された前記被測定液体の電気伝導率を測定することにより、該被測定液体の濃度を検出する液体濃度計測装置に関する。   The present invention relates to a non-stationary liquid concentration measuring apparatus applied to water quality surveys of factory effluent and river water, and the liquid to be measured (unsteady liquid) from a liquid supply means is collected in a sampling container, The present invention relates to a liquid concentration measurement device that detects the concentration of a liquid to be measured by measuring the electrical conductivity of the liquid to be measured collected in a container.

工場排水や河川水の水質調査においては、通常、水（被測定液体）が通流する水路に電気伝導率測定用の伝導度センサを設けて、該伝導度センサ及び該伝導度センサに接続された伝導度計によって水の電気伝導率を測定し、水中における汚染物質等の不純物の濃度を計測している。   In water quality surveys of industrial wastewater and river water, a conductivity sensor for measuring electrical conductivity is usually provided in the water channel through which water (liquid to be measured) flows, and the conductivity sensor and the conductivity sensor are connected. The conductivity of water is measured by a conductivity meter, and the concentration of impurities such as pollutants in water is measured.

しかしながら、前記のような液体濃度計測手段では、伝導度センサ及び伝導度計からなる電気伝導率測定手段の応答性が数秒単位であり、１秒以下の高応答性を必要とする非定常液体の濃度計測には適用できない。   However, in the liquid concentration measuring means as described above, the responsiveness of the electrical conductivity measuring means comprising a conductivity sensor and a conductivity meter is in units of a few seconds, and the liquid concentration measuring means is an unsteady liquid that requires a high responsiveness of 1 second or less. It cannot be applied to concentration measurement.

そこで、前記のような１秒以下の高応答性をそなえた液体濃度計測装置の一つとして、特許文献１（特開平８−４３２７４号公報）の技術が提供されている。   Therefore, as one of the liquid concentration measuring devices having the high response of 1 second or less as described above, the technique of Patent Document 1 (Japanese Patent Application Laid-Open No. 8-43274) is provided.

かかる技術においては、液体供給手段からの被測定液体を受け入れる中継容器及び該中継容器に接続される半径方向の供給ダクトを回転装置によって回転せしめ、該供給ダクトの下方に前記回転装置と同心円状に円周方向に沿って複数個連設されたサンプル瓶に、前記供給ダクトからの被測定液体を順次供給して、複数個のサンプル瓶に被測定液体を採取するように構成されている。   In such a technique, a relay container that receives the liquid to be measured from the liquid supply means and a radial supply duct connected to the relay container are rotated by a rotating device, and concentrically with the rotating device below the supply duct. The liquid to be measured from the supply duct is sequentially supplied to a plurality of sample bottles arranged continuously along the circumferential direction, and the liquid to be measured is collected in the plurality of sample bottles.

特開平８−４３２７４号公報JP-A-8-43274

しかしながら、前記特許文献１（特開平８−４３２７４号公報）の技術には、次のような解決すべき課題を抱えている。
即ち、前記特許文献１の技術に係る液体のサンプリング装置にあっては、回転装置の回転数を上げかつ回転装置におけるサンプル瓶の個数を多くすれば、このサンプリング装置を用いることによって１秒以下の高応答性をそなえた液体濃度計測装置を得ることは可能であるが、かかる特許文献１の技術は、被測定液体を効率的にサンプリングする手段について示されているにとどまり、被測定液体をサンプリングし、順次サンプリングされた被測定液体から連続的に伝導度センサを用いて電気伝導率を測定して該被測定液体内の不純物濃度を検出し、前記電気伝導率測定後の伝導度センサを洗浄して次のサンプリングにそなえる、という一連の液体濃度計測を効率的に行なう手段については全く示されていない。 However, the technique of Patent Document 1 (Japanese Patent Application Laid-Open No. 8-43274) has the following problems to be solved.
That is, in the liquid sampling device according to the technique of Patent Document 1, if the number of sample bottles in the rotating device is increased and the number of sample bottles in the rotating device is increased, the sampling device can be used for 1 second or less. Although it is possible to obtain a liquid concentration measuring device having high responsiveness, the technique disclosed in Patent Document 1 is limited to a means for efficiently sampling a liquid to be measured, and samples the liquid to be measured. Then, the electrical conductivity is measured continuously from the sampled liquid to be measured using the conductivity sensor to detect the impurity concentration in the measured liquid, and the conductivity sensor after the electrical conductivity measurement is washed. Thus, no means for efficiently performing a series of liquid concentration measurements to prepare for the next sampling is shown.

本発明はかかる従来技術の課題に鑑み、液体中における汚染物質等の不純物の濃度を計測するにあたり、被測定液体のサンプリング、サンプリングされた被測定液体から伝導度センサを用いての電気伝導率の測定及び被測定液体の濃度検出、及び電気伝導率測定後の伝導度センサの洗浄にいたる液体濃度計測の一連の動作を、高い応答性及び計測精度を保持しかつ少ない作業工数で以って行ない得る液体濃度計測装置を提供することを目的とする。   In view of the problems of the prior art, the present invention measures the concentration of impurities such as contaminants in a liquid by sampling the liquid to be measured, and measuring the electric conductivity using the conductivity sensor from the sampled liquid to be measured. Performs a series of operations to measure the concentration of the liquid to be measured and to detect the concentration of the liquid to be measured, and to clean the conductivity sensor after measuring the electrical conductivity, while maintaining high responsiveness and measurement accuracy with a small number of work steps. An object is to provide a liquid concentration measuring device to be obtained.

本発明はかかる目的を達成するもので、液体供給手段からの被測定液体をサンプリング用の容器に採取し、該容器内に採取された前記被測定液体の電気伝導率を測定することにより、該被測定液体の濃度を検出する液体濃度計測装置において、前記容器内にサンプリングされた前記被測定液体の電気伝導率を測定する伝導率センサと、該伝導率センサを移動可能に支持するとともに、前記電気伝導率の測定時には該伝導率センサを前記容器内に浸漬せしめて電気伝導率を測定可能とし、該電気伝導率の非測定時には前記伝導率センサを洗浄手段に移動せしめて該洗浄手段により該伝導率センサを洗浄可能としたセンサ支持・移動装置とをそなえて、前記容器内に被測定液体をサンプリングして前記伝導率センサで被測定液体の電気伝導率を測定し、電気伝導率の非測定時には前記センサ支持・移動装置によって伝導率センサを洗浄手段に移動せしめて該洗浄手段により該伝導率センサを洗浄するように構成したことを特徴とする。   The present invention achieves such an object, by collecting the liquid to be measured from the liquid supply means in a sampling container, and measuring the electric conductivity of the liquid to be measured collected in the container, In the liquid concentration measuring device for detecting the concentration of the liquid to be measured, a conductivity sensor for measuring the electric conductivity of the liquid to be measured sampled in the container, and the conductivity sensor are movably supported, and When measuring the electrical conductivity, the conductivity sensor is immersed in the container so that the electrical conductivity can be measured, and when the electrical conductivity is not measured, the conductivity sensor is moved to the cleaning means and the cleaning means moves the conductivity sensor. A sensor support / moving device capable of cleaning the conductivity sensor is used to sample the liquid to be measured in the container and measure the electrical conductivity of the liquid to be measured with the conductivity sensor. And, when not in the measurement of the electrical conductivity, characterized by being configured so as to wash the said transmission Shiruberitsu sensor by the cleaning means moved to the cleaning unit conductivity sensor by said sensor support and transfer device.

かかる発明において、具体的には次のように構成するのが好ましい。   In this invention, specifically, the following configuration is preferable.

（１）前記伝導率センサは前記センサ支持・移動装置に上下動可能に取付けられたセンサ支持具に前記容器内に出没可能に支持されるとともに、前記洗浄手段を純水が収容された純水槽で構成し、前記電気伝導率の測定時には前記センサ支持・移動装置によって前記センサ支持具を下降させ該伝導率センサを前記容器内に浸漬せしめて電気伝導率を測定可能とし、電気伝導率の非測定時には前記センサ支持・移動装置によって前記センサ支持具及び伝導率センサを移動させて該伝導率センサを前記純水槽内にて洗浄可能に構成する。   (1) The conductivity sensor is supported by a sensor support attached to the sensor support / moving device so as to be movable up and down so that the conductivity sensor can move in and out of the container, and the cleaning means contains a pure water tank. When the electrical conductivity is measured, the sensor support is moved down by the sensor support / moving device so that the conductivity sensor can be immersed in the container so that the electrical conductivity can be measured. At the time of measurement, the sensor supporting tool and the conductivity sensor are moved by the sensor supporting / moving device so that the conductivity sensor can be cleaned in the pure water tank.

（２）前記容器を、回転駆動される回転部材上に円周方向に沿って複数個連設され、前記液体供給手段からの該被測定液体を前記回転部材の回転に従い順次受け入れる回転容器で構成し、前記回転容器を前記回転部材により回転させ前記被測定液体を該回転容器内にサンプリングして、前記伝導率センサで被測定液体の電気伝導率を測定可能に構成する。   (2) A plurality of the containers are arranged in a circumferential direction on a rotating member that is driven to rotate, and are configured as a rotating container that sequentially receives the liquid to be measured from the liquid supply means according to the rotation of the rotating member. The rotating container is rotated by the rotating member, the liquid to be measured is sampled in the rotating container, and the electric conductivity of the liquid to be measured can be measured by the conductivity sensor.

かかる発明によれば、回転容器を回転駆動される回転部材上に円周方向に沿って複数個連設して前記回転部材により回転させ、液体供給手段からの被測定液体を該回転容器内に順次サンプリングし、センサ支持・移動装置に上下動可能に取付けられたセンサ支持具に支持された伝導率センサを該センサ支持・移動装置によって下降させ、前記回転容器内にサンプリングされた被測定液体内に浸漬せしめて該被測定液体の電気伝導率を測定し、この測定データにより該サンプリング液体（被測定液体）の濃度を検出する。
そして、前記被測定液体内への浸漬によって被測定液体が付着した伝導率センサは、前記センサ支持・移動装置によりセンサ支持具を介して洗浄手段に移動せしめられ、好ましくは純水が収容された純水槽からなる洗浄手段において洗浄せめられ、前記センサ支持・移動装置によって、次のサンプリング被測定液体の方へ戻され、次の工程に移る。 According to this invention, a plurality of rotating containers are continuously provided along a circumferential direction on a rotating member that is driven to rotate, and the rotating member is rotated by the rotating member, and the liquid to be measured from the liquid supply means is placed in the rotating container. The conductivity sensor that is sequentially sampled and supported by a sensor support that is attached to the sensor support / moving device so as to be movable up and down is lowered by the sensor support / moving device, and the sampled liquid is sampled in the rotating container. The electrical conductivity of the liquid to be measured is measured by immersing in the liquid, and the concentration of the sampling liquid (measuring liquid) is detected from the measurement data.
Then, the conductivity sensor to which the liquid to be measured is adhered by being immersed in the liquid to be measured is moved to the cleaning means by the sensor support / moving device via the sensor support, and preferably contains pure water. The sample is cleaned by a cleaning means comprising a pure water tank, and returned to the next sample liquid to be measured by the sensor support / moving device, and the process proceeds to the next step.

従って、かかる発明によれば、回転駆動される回転部材上に円周方向に沿って複数個連設した回転容器を回転させながら、被測定液体を該回転容器内に順次サンプリングするので、該回転容器の数を増加し、回転部材及び回転容器の回転数を増加しあるいは１回転あたりの回転容器数を増加することによりサンプリング時間を短縮でき、応答性が向上する。   Therefore, according to such an invention, the liquid to be measured is sequentially sampled in the rotating container while rotating a plurality of rotating containers arranged in a circumferential direction on the rotating member that is rotationally driven. By increasing the number of containers, increasing the number of rotations of the rotating member and the rotating container, or increasing the number of rotating containers per rotation, the sampling time can be shortened and the responsiveness is improved.

さらに前記被測定液体のサンプリング後、回転容器内にサンプリングされた被測定液体の電気伝導率を測定し、電気伝導率測定後の伝導率センサをセンサ支持・移動装置によって洗浄手段に移動せしめ、該洗浄手段により伝導率センサを洗浄して被測定液体を洗い落し、洗浄された前記伝導率センサをセンサ支持・移動装置によって、次のサンプリング被測定液体の方へ移動せしめるという、液体濃度計測の一連の動作を複数個の回転容器を回転させなが被測定液体を該回転容器内に順次サンプリングする作業と、サンプリングされた被測定液体の電気伝導率を測定する作業と、センサ支持・移動装置によって被測定液体の電気伝導率測定後の伝導率センサを洗浄手段側と回転容器側との間を往復移動させる作業と、伝導率センサを洗浄手段により洗浄する作業とを連続的に行なうことができるので、１回目の被測定液体サンプリングから次のサンプリングまでの計測サイクル時間を短縮できて、計測精度を高く保持しつつ、非定常液体の濃度計測に好適な高い応答性を保持できる。また、前記のように液体濃度計測の一連の動作を連続的に行なうことができるので、少ない作業工数で液体濃度計測を行なうことができる。   Further, after sampling the liquid to be measured, the electric conductivity of the liquid to be measured sampled in the rotating container is measured, and the electric conductivity sensor after the electric conductivity measurement is moved to the cleaning means by the sensor support / moving device, A series of liquid concentration measurement in which the conductivity sensor is washed by the washing means to wash off the liquid to be measured, and the washed conductivity sensor is moved toward the next sampling liquid to be measured by the sensor support / moving device. The operation of rotating the plurality of rotating containers while sampling the liquid to be measured sequentially into the rotating container, the work of measuring the electrical conductivity of the sampled liquid to be measured, and the sensor supporting / moving device Work to reciprocate the conductivity sensor after measuring the electrical conductivity of the liquid to be measured between the cleaning means side and the rotating container side, and the conductivity sensor to the cleaning means Since the cleaning operation can be performed continuously, the measurement cycle time from the first measured liquid sampling to the next sampling can be shortened, and the concentration measurement of unsteady liquid is performed while maintaining high measurement accuracy. High responsiveness suitable for the above can be maintained. Further, as described above, since a series of operations for liquid concentration measurement can be performed continuously, it is possible to perform liquid concentration measurement with a small number of work steps.

またかかる発明において好ましくは、前記容器を、回転駆動される回転部材上に該回転部材の円周方向に沿って複数個環状に連設された容器群を前記回転部材の半径方向に複数層設けてなり、前記液体供給手段からの該被測定液体を前記回転部材の回転に従い順次受け入れる回転容器で構成し、前記液体供給手段を前記回転部材の半径方向に移動せしめることにより前記複数層の回転容器の個々に前記被測定液体を供給可能に構成し、さらに前記複数層の回転容器のそれぞれに対応して前記伝導率センサを設けて前記電気伝導率の測定時には該伝導率センサを前記容器内に浸漬せしめて電気伝導率を測定可能とするとともに、該電気伝導率の非測定時には前記伝導率センサを洗浄手段に移動せしめて該洗浄手段により該伝導率センサを洗浄可能に構成する。   In this invention, it is preferable that a plurality of container groups in which a plurality of the containers are connected in a ring shape along the circumferential direction of the rotating member are provided on the rotating member that is driven to rotate in the radial direction of the rotating member. And a plurality of layers of rotating containers by moving the liquid supplying means in the radial direction of the rotating member. The rotating container sequentially receives the liquid to be measured from the liquid supplying means according to the rotation of the rotating member. The liquid to be measured can be supplied individually, and the conductivity sensor is provided corresponding to each of the plurality of layers of rotating containers, and the conductivity sensor is placed in the container when measuring the electric conductivity. The electrical conductivity can be measured by immersion, and when the electrical conductivity is not measured, the electrical conductivity sensor can be cleaned by moving the electrical conductivity sensor to the cleaning device. It is configured.

このように構成すれば、回転部材の円周方向に沿って複数個環状に連設された容器群を半径方向に複数層設けた回転容器に、液体供給手段を該回転容器の半径方向に移動させながら順次被測定液体をサンプリングするので、サンプリング間隔を目標間隔に保持した状態でサンプリング時間を長く採ることができて、液体濃度の計測精度を上げることができる。   According to this structure, the liquid supply means is moved in the radial direction of the rotating container to the rotating container in which a plurality of annularly arranged container groups are provided in the radial direction along the circumferential direction of the rotating member. Since the liquid to be measured is sequentially sampled while the sampling interval is kept at the target interval, the sampling time can be increased and the liquid concentration measurement accuracy can be increased.

またかかる発明において好ましくは、前記容器を、回転駆動される回転部材上に円周方向に沿って複数個連設され、前記液体供給手段からの該被測定液体を前記回転部材の回転に従い順次受け入れる回転容器で構成して、該回転容器を前記回転部材が連結された回転軸の軸線に沿って複数段配設し、前記液体供給手段を前記複数段の回転容器毎に前記被測定液体を供給可能に該回転容器と同数設け、前記各液体供給手段には前記被測定液体の前記回転容器への供給、遮断を切り換える切換弁を設け、さらに前記複数段の回転容器のそれぞれに対応して前記伝導率センサを設けて前記電気伝導率の測定時には該伝導率センサを前記回転容器内に浸漬せしめて電気伝導率を測定可能とするとともに、該電気伝導率の非測定時には前記伝導率センサを洗浄手段に移動せしめて該洗浄手段により該伝導率センサを洗浄可能に構成する。   In the invention, preferably, a plurality of the containers are provided in a circumferential direction on a rotating member that is driven to rotate, and the liquid to be measured from the liquid supply means is sequentially received according to the rotation of the rotating member. A rotating container is provided, the rotating container is arranged in a plurality of stages along the axis of the rotating shaft to which the rotating member is connected, and the liquid supply means supplies the liquid to be measured for each of the rotating containers in the plurality of stages. Possible to provide the same number as the rotating containers, and each liquid supply means is provided with a switching valve for switching between supply and shutoff of the liquid to be measured to the rotating containers, and further corresponding to each of the plurality of rotating containers. A conductivity sensor is provided to measure the electrical conductivity by measuring the electrical conductivity by immersing the conductivity sensor in the rotating container, and when the electrical conductivity is not measured, the conductivity sensor And moved to the cleaning means for cleaning configured to enable said transmission Shiruberitsu sensor by said cleaning means.

このように構成すれば、回転容器を回転駆動される回転軸の軸線に沿って複数段配設するとともに、前記液体供給手段を複数段の回転容器毎に被測定液体を供給可能に該回転容器と同数設けて、切換弁により前記被測定液体の前記回転容器への供給、遮断を切り換えて、各段の回転容器に任意のサンプリングタイミングで被測定液体を供給できることとなるので、サンプリング間隔を目標間隔に保持した状態でサンプリング時間を長く採ることができて、液体濃度の計測精度を上げることができる。   With this configuration, the rotary container is arranged in a plurality of stages along the axis of the rotary shaft that is rotationally driven, and the liquid supply means can supply the liquid to be measured to each of the multiple stages of the rotary containers. Since the liquid to be measured can be supplied to the rotating container at each stage at any sampling timing by switching the supply and shutoff of the liquid to be measured to the rotating container by the switching valve, the sampling interval is set as the target. Sampling time can be increased while maintaining the interval, and the liquid concentration measurement accuracy can be increased.

またかかる発明において好ましくは、前記容器内に純水を供給可能な純水供給ラインを設けるとともに、該純水供給ラインを開閉して前記容器内における前記被測定液体の濃度が一定濃度を超えたとき、該純水供給ラインを開いて該容器内に純水を供給せしめる純水供給弁をそなえる。   In the invention, preferably, a pure water supply line capable of supplying pure water is provided in the container, and the concentration of the liquid to be measured in the container exceeds a certain concentration by opening and closing the pure water supply line. In some cases, a pure water supply valve is provided to open the pure water supply line and supply pure water into the container.

このように構成すれば、容器内における被測定液体の濃度が一定濃度を超えたときに純水供給弁が自動的に開弁して、純水供給ラインから前記容器内に純水を供給できるので、該容器内の濃度を過濃とすることなく、所要の濃度に保持できるとともに、かかる濃度保持のための作業工数を低減できる。   If comprised in this way, when the density | concentration of the to-be-measured liquid in a container exceeds a fixed density | concentration, a pure water supply valve will open automatically, and a pure water can be supplied in the said container from a pure water supply line Therefore, the concentration in the container can be maintained at a required concentration without being excessively concentrated, and the number of work steps for maintaining the concentration can be reduced.

本発明によれば、回転駆動される回転部材上に円周方向に沿って複数個連設した回転容器を回転させながら、被測定液体を該回転容器内に順次サンプリングするので、該回転容器の数を増加し、回転部材及び回転容器の回転数を増加しあるいは１回転あたりの回転容器数を増加することによりサンプリング時間を短縮でき、応答性が向上する。   According to the present invention, the liquid to be measured is sequentially sampled in the rotating container while rotating a plurality of rotating containers arranged in a circumferential direction on the rotating member that is rotationally driven. By increasing the number, increasing the number of rotations of the rotating member and the rotating container, or increasing the number of rotating containers per rotation, the sampling time can be shortened and the responsiveness is improved.

さらに液体濃度計測の一連の動作である、複数個の回転容器を回転させながら被測定液体を該回転容器内に順次サンプリングする作業と、サンプリングされた被測定液体の電気伝導率を測定する作業と、センサ支持・移動装置によって被測定液体の電気伝導率測定後の伝導率センサを洗浄手段側と回転容器側との間を往復移動させる作業と、伝導率センサを洗浄手段により洗浄する作業とを連続的に行なうことができるので、１回目の被測定液体サンプリングから次のサンプリングまでの計測サイクル時間を短縮できて、計測精度を高く保持しつつ、非定常液体の濃度計測に好適な高い応答性を保持できる。また、前記のように液体濃度計測の一連の動作を連続的に行なうことができるので、少ない作業工数で液体濃度計測を行なうことができる。   Furthermore, a series of operations for liquid concentration measurement, an operation of sequentially sampling the liquid to be measured in the rotating container while rotating a plurality of rotating containers, and an operation of measuring the electrical conductivity of the sampled liquid to be measured The work of moving the conductivity sensor after measuring the electrical conductivity of the liquid to be measured between the cleaning means side and the rotating container side by the sensor support / moving device and the work of cleaning the conductivity sensor by the cleaning means Since it can be performed continuously, the measurement cycle time from the first liquid measurement to the next sampling can be shortened, and high responsiveness suitable for concentration measurement of unsteady liquid while maintaining high measurement accuracy Can be held. Further, as described above, since the series of operations for measuring the liquid concentration can be performed continuously, the liquid concentration can be measured with a small number of work steps.
