Description

本発明は、イオン交換塔の覗き窓に関する。   The present invention relates to a viewing window of an ion exchange tower.

粒状のイオン交換樹脂を充填し、被処理水を脱塩処理するイオン交換塔を運転する際には、定期的に或いは運転条件の変更の都度、塔の胴部又は頭部に設けた覗き窓を通して塔内部を覗き見て、塔内部の状態を把握する必要がある。例えば、アニオン交換樹脂とカチオン交換樹脂の双方を充填した混床式のイオン交換塔の運転では、再生工程において両イオン交換樹脂を分離した際に形成される上層のアニオン交換樹脂層と下層のカチオン交換樹脂層との界面を検知するために、界面が位置すると予想される場所に予め覗き窓を設けて、覗き窓から界面の位置を把握している。   When operating an ion exchange tower filled with granular ion exchange resin and desalting the water to be treated, a viewing window provided on the trunk or head of the tower periodically or whenever the operating conditions are changed It is necessary to look inside the tower through and understand the inside of the tower. For example, in the operation of a mixed bed type ion exchange column packed with both an anion exchange resin and a cation exchange resin, the upper anion exchange resin layer and the lower cation formed when the both ion exchange resins are separated in the regeneration step. In order to detect the interface with the exchange resin layer, a viewing window is provided in advance at a position where the interface is expected to be located, and the position of the interface is grasped from the viewing window.

イオン交換塔に設けた覗き窓には、表面が平滑な窓ガラスが固定されていたが、表面が平滑な面の窓ガラスはでは、イオン交換樹脂、特にアニオン交換樹脂、なかでも破砕されて半割状態のイオン交換樹脂が付着しやすい。このように、覗き窓に樹脂が付着するとカチオン交換樹脂層とアニオン交換樹脂層との境界面が判別しにくくなる。そこで、透明板を通して容器内部を視認し、又は容器内部の状態を検知する覗き窓としては、容器内部に面する透明板の板面が、磨りガラス状の凹凸面で型成された覗き窓が知られている。（特許文献１参照）   A window glass with a smooth surface was fixed to the viewing window provided in the ion exchange tower. However, with a window glass with a smooth surface, an ion exchange resin, particularly an anion exchange resin, especially a crushed and half-finished glass. Split ion exchange resin is easy to adhere. Thus, when the resin adheres to the viewing window, it becomes difficult to distinguish the boundary surface between the cation exchange resin layer and the anion exchange resin layer. Therefore, as a viewing window for visually recognizing the inside of the container through the transparent plate or detecting the state of the inside of the container, there is a viewing window in which the surface of the transparent plate facing the inside of the container is formed with a polished glass-like uneven surface. Are known. (See Patent Document 1)

また、覗き窓を通して塔内部を撮像するＣＣＤカメラ（図示せず）を設け、ＣＣＤカメラで撮像した界面及び上面の画像を画像解析して、界面の位置を検出し、イオン交換塔を自動制御することも提案されている。（特許文献２参照）
特開２０００−１５７８６０号公報 特開平１０−２３５１８４ In addition, a CCD camera (not shown) that captures the inside of the tower through the viewing window is provided, and the interface and upper surface images captured by the CCD camera are analyzed to detect the position of the interface and automatically control the ion exchange tower. It has also been proposed. (See Patent Document 2)
JP 2000-157860 A JP 10-235184 A

しかしながら、特許文献１に記載の磨りガラス状の凹凸面で型成された透明板を採用した覗き窓からＣＣＤカメラで撮影したイオン交換樹脂の画像を処理してカチオン交換樹脂とアニオン交換樹脂の分離界面を制御した場合に、イオン交換塔の覗き窓にイオン交換樹脂（アニオン交換樹脂）が付着し、この付着したイオン交換樹脂の位置を検知してカチオン交換樹脂層とアニオン交換樹脂層の境界面を誤判別し、真の境界面を検知できないことがあり、イオン交換樹脂の付着防止効果、及び、付着した樹脂の剥離効果がより改善された覗き窓が望まれていた。   However, separation of the cation exchange resin and the anion exchange resin by processing an image of the ion exchange resin taken with a CCD camera from a viewing window employing a transparent plate formed with a polished glass-like uneven surface described in Patent Document 1. When the interface is controlled, ion exchange resin (anion exchange resin) adheres to the observation window of the ion exchange tower, and the position of the adhering ion exchange resin is detected to detect the boundary surface between the cation exchange resin layer and the anion exchange resin layer. Therefore, there is a case where a true boundary surface cannot be detected, and a viewing window with improved effects of preventing the adhesion of the ion exchange resin and removing the adhered resin has been desired.

解決しようとする課題は、イオン交換樹脂の付着防止効果が有効で、また、付着した樹脂の剥離が十分可能なイオン交換塔の覗き窓を提供することである。   The problem to be solved is to provide a viewing window for an ion exchange tower that is effective in preventing the adhesion of the ion exchange resin and that can sufficiently separate the adhered resin.

上記課題を解決するために請求項１に記載の発明は、イオン交換塔の覗き窓であって、覗き窓に使用されている透明板の塔内側の表面に縦方向に直線状のスリット溝が複数設けられていることを特徴とするイオン交換塔の覗き窓である。   In order to solve the above-mentioned problems, the invention according to claim 1 is a viewing window of an ion exchange tower, wherein a linear slit groove is formed in a vertical direction on a surface inside the tower of a transparent plate used for the viewing window. It is the observation window of the ion exchange tower characterized by being provided with two or more.

また、請求項２に記載の発明は、前記縦方向に直線状のスリット溝の構造は、前記透明板の横断面が塔内側の表面側にサインカーブの波型となるように設けられている請求項１に記載のイオン交換塔の覗き窓である。   According to a second aspect of the present invention, the structure of the slit grooves linear in the vertical direction is provided so that the cross section of the transparent plate has a sine curve wave shape on the surface side inside the tower. It is a viewing window of the ion exchange tower of Claim 1.

また、請求項３に記載の発明は、前記縦方向に真直ぐな複数のスリット溝は、横断面が半円型のスリット溝である請求項１に記載のイオン交換塔の覗き窓である。 Further, an invention according to claim 3, wherein the longitudinal direction straight plurality of slit grooves, the cross section is a viewing window of the ion exchange column according to claim 1 which is slit groove of semi-circular.

また、請求項４に記載の発明は、前記縦方向に真直ぐな複数のスリット溝は、横断面が楔型のスリット溝である請求項１に記載のイオン交換塔の覗き窓である。 According to a fourth aspect of the present invention, in the ion exchange tower according to the first aspect, the plurality of slit grooves that are straight in the longitudinal direction are wedge-shaped slit grooves.

本発明によれば、無機ガラス又は透明な合成樹脂製のイオン交換塔の覗き窓の内側（交換塔の内側）に縦方向に直線状のスリット（溝）を切ることにより付着しようとするイオン交換樹脂と覗き窓の接触面積を減少させ、且つ逆洗上昇流による引き剥がし効果を利用して、覗き窓にイオン交換樹脂が付着しないようになった。   According to the present invention, an ion exchange that is intended to adhere by cutting a linear slit (groove) in the vertical direction inside the viewing window (inside the exchange tower) of an ion exchange tower made of inorganic glass or transparent synthetic resin. The contact area between the resin and the observation window is reduced, and the ion exchange resin is prevented from adhering to the observation window by utilizing the peeling effect by the backwash upflow.

本発明の一実施形態について詳細に説明する。図１は、本発明の一実施形態のイオン交換塔の覗き窓の一部の拡大斜視図、図２は、本発明の他の実施形態の横断面図である。   An embodiment of the present invention will be described in detail. FIG. 1 is an enlarged perspective view of a part of a viewing window of an ion exchange tower according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of another embodiment of the present invention.

図１に示す透明板１は、イオン交換塔の覗き窓に使用されている。この透明板１は、通常の無機ガラスでもよいが、アクリル樹脂など透明でかつ強度を有する合成樹脂製であってもよい。透明板１は、イオン交換塔の塔外側の表面Ａは平滑面となっていて、塔内側の表面２には、縦方向に直線状のスリット溝３が複数設けられている。また、透明板１の横断面が塔内側の表面２側にサインカーブの波型となるように設けられている。   A transparent plate 1 shown in FIG. 1 is used for a viewing window of an ion exchange tower. The transparent plate 1 may be ordinary inorganic glass, but may be made of a synthetic resin that is transparent and strong, such as an acrylic resin. The transparent plate 1 has a smooth surface A on the outer side of the ion exchange column, and a plurality of linear slit grooves 3 are provided on the surface 2 on the inner side of the column in the vertical direction. Further, the transparent plate 1 is provided so that the cross section of the transparent plate 1 has a sine curve waveform on the surface 2 side inside the tower.

上記透明板１の内側の表面２に設けた縦方向に真直ぐな複数のスリット溝３の構造を図２に示す。   FIG. 2 shows the structure of a plurality of slit grooves 3 straight on the surface 2 provided on the inner surface 2 of the transparent plate 1.

図２の波型−１は、透明板１の内側の表面２側に、透明板１の横断面がサインカーブの波型となるように形成したもので、サインカーブの波型の寸法はピッチ０．６ｍｍ、深さ０．３ｍｍである。   2 is formed on the inner surface 2 side of the transparent plate 1 so that the cross section of the transparent plate 1 has a waveform of a sine curve. The size of the waveform of the sine curve is a pitch. 0.6 mm and depth 0.3 mm.

図２の波型−２は、透明板１の内側の表面２側に、透明板１の横断面がサインカーブの波型となるようにスリット溝を形成したもので、サインカーブの波型の寸法はピッチ０．３ｍｍ、深さ０．２ｍｍである。   2 has a slit groove formed on the inner surface 2 side of the transparent plate 1 so that the cross section of the transparent plate 1 has a sine curve waveform. The dimensions are a pitch of 0.3 mm and a depth of 0.2 mm.

図２の楔型は、透明板１の内側の表面２側に、複数の楔型のスリット溝（Ｖ字のスリット溝）が間欠的に連続するように形成したもので、間欠的に連続する楔型のスリット溝の寸法はピッチ０．３ｍｍ、深さ０．３ｍｍである。   2 is formed such that a plurality of wedge-shaped slit grooves (V-shaped slit grooves) are intermittently continuous on the inner surface 2 side of the transparent plate 1 and are intermittently continuous. The wedge-shaped slit groove has a pitch of 0.3 mm and a depth of 0.3 mm.

図２の半円型−１は、透明板１の内側の表面２側に、複数の半円型のスリット溝が間欠的に連続するように形成したもので、間欠的に連続する半円型のスリット溝の寸法はピッチ０．６ｍｍ、深さ０．３ｍｍである。   2 is formed such that a plurality of semicircular slit grooves are intermittently continued on the inner surface 2 side of the transparent plate 1, and is intermittently continuous. The slit grooves have a pitch of 0.6 mm and a depth of 0.3 mm.

図２の半円型−２は、透明板１の内側の表面２側に、複数の半円型のスリット溝が間欠的に連続するように形成したもので、間欠的に連続する半円型のスリット溝の寸法はピッチ０．３ｍｍ、深さ０．２ｍｍである。   2 is formed so that a plurality of semicircular slit grooves are intermittently continued on the inner surface 2 side of the transparent plate 1, and is intermittently continuous. The slit grooves have a pitch of 0.3 mm and a depth of 0.2 mm.

透明板１の内側の表面２に設けた縦方向に真直ぐな複数のスリット溝３の構造は、図２に示したいずれの形状でもよいが、好ましくはサインカーブの波型、半円型の曲面からなるものがよい。スリット溝３の構造は、楔型でもよいが、透明板１の内側の凸部の表面に平面部があるより、波型のように連続して曲面になっている方が、イオン交換樹脂が付着しにくい。   The structure of the plurality of slit grooves 3 straight in the vertical direction provided on the inner surface 2 of the transparent plate 1 may be any of the shapes shown in FIG. 2, but is preferably a sine curve corrugated or semicircular curved surface. The thing which consists of is good. The structure of the slit groove 3 may be wedge-shaped, but the ion-exchange resin is more curved in a continuous shape like a corrugated shape rather than having a flat surface on the surface of the convex portion inside the transparent plate 1. Hard to adhere.

このように、透明板１の内側の表面２には縦方向に真直ぐな複数のスリット溝３が設けられていると、イオン交換樹脂と透明板１との接触面積が極めて小さくなりイオン交換樹脂の付着が生じにくい。透明板１の表面部のスリット溝３の幅は、イオン交換樹脂の直径と同程度以下とするのが好ましい。また、スリット溝３を設けることにより、イオン交換樹脂と接する透明板１の接触面積が小さくなり、付着しにくくなるが、曲面であれば点接触に近くなりより一層付着しにくい。また、破砕したイオン交換樹脂が溝内に入っても曲面であれば点接触となるので付着しにくい。   As described above, when a plurality of slit grooves 3 that are straight in the vertical direction are provided on the inner surface 2 of the transparent plate 1, the contact area between the ion exchange resin and the transparent plate 1 becomes extremely small. Adhesion hardly occurs. It is preferable that the width of the slit groove 3 on the surface portion of the transparent plate 1 is equal to or less than the diameter of the ion exchange resin. Further, by providing the slit groove 3, the contact area of the transparent plate 1 in contact with the ion exchange resin is reduced and it is difficult to adhere to it, but if it is a curved surface, it becomes close to point contact and becomes more difficult to adhere. Further, even if the crushed ion exchange resin enters the groove, if it is a curved surface, it becomes a point contact and is difficult to adhere.

仮に付着しても、付着樹脂と透明板１の間に空間が存在し、そしてスリット溝が縦（上下、垂直）方向に設けられているから、水を上向流で通水することにより、付着樹脂と透明板１の間の空間に水を流すことができ、付着樹脂の裏側からの水圧で付着樹脂を離させることができる。また、この上向流通水時には同様な作用により、透明板１へのイオン交換樹脂の付着は防止される。   Even if temporarily attached, there is a space between the attached resin and the transparent plate 1 and the slit grooves are provided in the vertical (vertical, vertical) direction, so by passing water in an upward flow, Water can be passed through the space between the adhesive resin and the transparent plate 1, and the adhesive resin can be separated by water pressure from the back side of the adhesive resin. Moreover, adhesion of the ion exchange resin to the transparent plate 1 is prevented by the same action during the upward circulation.

本発明は前記実施例に限定されるものではなく、特許請求の範囲に記載された本発明を逸脱することがなければ、種々の設計変更が可能であり、前記実施例に限定されないことはいうまでもない。   The present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the present invention described in the claims, and the present invention is not limited to the above-described embodiments. Not too long.
