Thus, the liquid retained on the tray 5 is guided from the orifice 12 into the cylinder of the chimney 7 from the orifice 12 at an appropriate flow rate by the potential energy corresponding to the height between the liquid upper surface and the orifice 12. The liquid guided into the cylinder of the chimney 7 collides with the baffle 21 as shown by an arrow in FIG.
Is evenly dispersed within. The liquid flowing down the baffle 21 and the wings 23 stays at the same edge due to the constricted portion of the baffle 21 and the narrowed portion formed by chamfering each edge of the guide 24, or the liquid at the back of the flow surface. Is released in a certain direction without wrapping around, and is uniformly dispersed and led to the catalyst layer 2. This chamfering is not always necessary, but if it is not chamfered, the direction in which the liquid will flow out is not determined, and the dispersibility deteriorates. In addition, the liquid that is changed in direction at the free end of the long side of the wing portion 23 and collides into the chimney 7 and propagates on the inner wall surface of the chimney 7 is provided at the lower notch 11 provided at an appropriate interval at the lower end of the chimney 7. , Flows down without being concentrated at one place, and is dispersed and guided to the catalyst layer 2. Then, the liquid dispersed by the baffle 21 and the wing portion 23 and guided to the catalyst layer 2 from the chimney 7 is scattered in a shower shape over a wide area by a spreading portion formed below the chimney 7.

By setting the liquid flowing out of the orifice 12 at an appropriate flow rate, the liquid that has collided with the baffle 21 is guided to the baffle 21, the wing 23, the inner wall of the chimney 7 and the like, and is uniformly dispersed in the chimney 7. You. If the flow rate is low, the liquid does not reach the baffle 21 or the impact force is weak. Conversely, if the flow rate is too high, liquids interfere with each other inside the chimney 7 and good dispersion cannot be obtained. The flow rate of the liquid is adjusted by the height from the orifice 12 to the liquid level. For example, when handling oil, etc.,
The inner diameter of the chimney 7 is preferably 5 to 15 cm, and particularly preferably about 7 to 13 cm, although the inner diameter of the chimney 7 is preferably about 5 to 15 cm, although it varies somewhat depending on the conditions in the container.
Then, it is desirable that the diameter of the orifice 12 be determined so that the height from the orifice 12 to the liquid surface is about 10 to 30 cm. However, in the case of a liquid that is easily contaminated such as heavy oil, the inner diameter of the orifice 12 is preferably 6 mm or more, if possible, in order to prevent the orifice 12 from being blocked. Also, the height from the orifice 12 to the liquid level is
If it is 10 cm or more, the influence of the level of the tray 5 depends on the size of the container, but can be almost ignored.

Here, the height difference between the upper ends of the orifices 12a and 12b and the upper end of the baffle 21 is set so that the liquid that has collided with the baffle 21 has a length (at least 2 cm) that does not jump over the upper end of the baffle 21. Is desirable to obtain a uniform dispersion. Further, the scattering range can be adjusted by changing the spread angle of the spread portion formed below the chimney 7. Furthermore, baffle 21,

Therefore, in the dispersing apparatus according to the first and second embodiments thus configured, the tray 5 for dividing the space in the container 1 into the space on the inlet 3 side and the space on the catalyst layer 2 side. A plurality of chimneys 7 are provided, a roof 8 is disposed above the chimney 7 at a predetermined distance from an upper end of the chimney 7, and an orifice 12 is formed on a side surface of the chimney 7. If the liquid level of the liquid staying on the tray 5 has a certain height beyond the orifice 12 even if it occurs, a substantially uniform outflow of liquid can be introduced into each chimney 7. Further, by providing dispersing means 20 and 30 corresponding to the orifice 7 in the chimney 7, the diameter of the orifice 12 is adjusted with respect to the liquid guided from the inlet 3 into the container 1 and stays on the tray 5. By setting the height of the liquid to a desired height, the liquid guided into the chimney 7 can be satisfactorily dispersed in the space on the catalyst layer 2 side together with the gas passing through the chimney 7. Further, by forming the upper and lower notches 10 and 11 at the upper and lower ends of the chimney 7, the upper notch 10 can cope with an increase in the amount of liquid to be processed. The liquid that is transmitted from the surface to the lower end and collected can be dispersed. Then, the liquid that is uniformly dispersed in the catalyst layer 2 can be caused to fall in a wide area in the form of a shower by the expanded portion below the chimney 7. Further, by disposing the chimneys 7 provided with the respective dispersing means 20 and 30 on the tray evenly, the liquid and the gas can be uniformly dispersed and flow down in the lower space of the tray 5.
