Description
【考案の詳細な説明】 ［産業上の利用分野］ 本考案は液の分散装置に関し、特に沈降性スラッジの
含有液を処理して、その上澄液を均一に分散する装置に
関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a liquid dispersion device, and more particularly to a device for treating a liquid containing sedimentable sludge to uniformly disperse the supernatant liquid.
［従来の技術］ 熱或いは物質移動操作におけるガス冷却或いはガス吸

これらの処理塔のうち、テラレット（商品名）やラシヒ
リング等の充填物を充填した充填塔が建設費や運転の容
易さから広く使用されている。[Prior Art] A packed tower, a perforated plate tower and a perforated plate tower, or a spray type is used according to the purpose as a processing device for gas cooling, gas absorption, and diffusion in heat or mass transfer operation.
Among these processing towers, a packed tower filled with a packing material such as Terralet (trade name) or Raschig ring is widely used because of its construction cost and easy operation.
このような処理塔を用いて、例えば気液の分散を行う

に保つ必要がある。また充填塔の場合は、液に偏流が生
じる傾向がある。この偏流を防止して塔内に均一に分散
させるため各種の分散板が提案されている。There are various problems in performing gas-liquid dispersion using such a processing tower. For example, when using a perforated plate column and a perforated plate column, in order to uniformly disperse the liquid in these columns, it is necessary to keep the horizontal level of the perforated plate or perforated plate provided in each stage accurately. In the case of a packed tower, the liquid tends to have a drift. Various dispersion plates have been proposed to prevent this uneven flow and to disperse the particles uniformly in the tower.

方向の推力を増し、逆に少ない流量ではトラフ側の流れ
が散漫になり、更にトラフ内の液の傾斜により、液の分
散が妨げられる。However, due to recent industrial diversification, there are increasing examples of using a liquid containing sludge for operations such as general gas cooling, liquid cooling, and oxidation of black liquor in the pulp industry. In order to disperse the liquid containing the sludge, the conventional liquid disperser cannot be used because of the clogging of the holes and voids constituting them. For dispersion of such occlusive liquid, for example, Hydrocarbon Processing, July, P.47, 1980 and Chemi
V-notch type liquid dispersers such as those described in cal Engineering, April P.124, 1989 can be used. Since this notch type disperser is an overflow type, it does not block the holes like a porous type, and since the bottom of the trough functions as a sedimentation tank, a part of suspended matter is removed here, It is a disperser that is strong against blockage. However, in terms of liquid dispersibility, the performance is lower than that of the porous disperser. For example, the V-notch type increases the thrust in the horizontal direction against excess liquid, and conversely the flow on the trough becomes diffuse at a small flow rate, and further, the inclination of the liquid in the trough hinders the dispersion of the liquid.
一般の充填塔において、ラシヒリングのような面構造
充填物では液が横に広がる傾向を有するため、液分散が

従ってノッチトラフのように分散の粗い分散器では線構
造充填物の性能を充分に発揮させることは困難である。
さらに液量の変化は、液の落下位置を不均一としこれも
また充填物の性能を充分に発揮できない一因となる。In a general packed tower, a surface structured packing such as Raschig ring has a tendency that the liquid spreads laterally, so that some effect can be expected even when the liquid dispersion is rough. However, in the case of a linear structure packing such as a terraret in which the liquid drops vertically, the initial liquid dispersion at the top of the tower is maintained as it is at the bottom of the tower, so the quality of the first liquid dispersion has a great influence on the performance of the packed column.
Therefore, it is difficult to sufficiently exhibit the performance of the line-structure packing with a disperser having a coarse dispersion such as a notch trough.
Further, the change in the liquid amount makes the liquid drop position non-uniform, which also contributes to the insufficient performance of the filling material.

比較して格段に優れる。[Effect of the device] The horizontal hole type liquid disperser according to the present invention causes the sludge in the supplied undiluted solution to settle and separate at the bottom of the primary trough, and guides the supernatant liquid to the secondary trough. By making it collide with baffles provided on the side surface or both sides of the secondary trough, without causing clogging by sludge,
The liquid can be dispersed uniformly. In addition, the liquid disperser of the present invention is far superior to the conventional notched trough with respect to the inclination of the trough.
一般に流量は次の計算式で表わされる（機械工学便
覧、第５版、日本機械学会1974参照）。すなわちノッチ
ドトラフ（90°堰の場合） Ｑ＝（8/15）θ/2C（2g）1/2H5/2m3/sec Ｑ∝H5/2 （１） オリフィスの場合 Ｑ＝CA（2g）1/2H1/2 Ｑ∝H1/2 （２） （但し、H:液ヘッド（ｍ）、Q:流量（ｍ３/S）、C:流量
係数、A:孔の面積（ｍ２）、θ：ノッチの頂角） ここでノッチドトラフと本考案の横孔式トラフが同寸法

とし、Ｑ点における液深を40mmとして両者の液深の差が
共に10mmとする。しかして両者のＰ点における液深を共
に100％とすると、Ｑ点における両者の液量は上記
（１）及び（２）式から下記のようになる。Generally, the flow rate is represented by the following formula (see Mechanical Engineering Handbook, 5th edition, Japan Society of Mechanical Engineers 1974). That is, notched trough (in case of 90 ° weir) Q = (8/15) θ / 2C (2g) 1/2 H 5/2 m 3 / sec Q∝H 5/2 (1) In case of orifice Q = CA ( 2g) 1/2 H 1/2 Q∝H 1/2 (2) (however, H: liquid head (m), Q: flow rate (m 3 / S), C: flow coefficient, A: hole area ( m 2 ), θ: vertical angle of notch) Here, assuming that the notched trough and the horizontal hole type trough of the present invention have the same dimensions, the liquid depth at the point P of both troughs is 50 mm.
And the liquid depth at point Q is 40 mm, and the difference between both liquid depths is 10 mm. If the liquid depths at both P points are 100%, the liquid amounts at both Q points are as follows from the above equations (1) and (2).
ノッチドトラフの場合、100（40/50）5/2＝57.2％ 本考案の横孔式トラフ100（40/50）1/2＝89.4％ すなわち、本考案の液分散器の方が分散性が格段に優れ

ける液量を100％とすると、前記と同様に、（90/100）
1/2＝94.9％となり、本考案の横孔式トラフは液の分散
性がよいことを示す。In the case of a notched trough, 100 (40/50) 5/2 = 57.2% The horizontal hole trough 100 (40/50) 1/2 = 89.4% of the present invention, that is, the liquid disperser of the present invention has a higher dispersibility. Remarkably excellent. Further, since the horizontal hole type trough of the present invention can arbitrarily set the liquid depth, the liquid depths at the points P and Q2 are 100 mm and 9 respectively.
Assuming that the difference between the liquid depths at points P and Q is 10 mm and the liquid amount at point P is 100% with 0 mm, the same as above (90/100)
1/2 = 94.9%, which shows that the horizontal hole type trough of the present invention has good liquid dispersibility.

れた効果が得られる。As described above, the lateral hole type liquid disperser according to the present invention can maintain good liquid dispersibility without being affected by the inclination of the trough and can prevent clogging by sludge as compared with the conventional notched trough. . Therefore, it is possible to obtain an excellent effect that special accuracy is not required at the time of installation, the structure is simple, and the maintenance is easy.
