[Problem that the idea aims to solve]

However, in the conventional structure, the ventilation nozzle 36 serves both gas circulation and liquid circulation. Therefore, it is recommended to increase the size of the ventilation nozzle 36 or increase the number of ventilation nozzles 36. Otherwise, the flowability of liquid would be poor. In other words, the liquid flows from top to bottom. The gas passes through the ventilation nozzle 36, but the gas forms a counterflow from the bottom to the top. This is because the flow of the liquid is obstructed by the gas. For this reason, the ventilation nozzle In the conventional structure when the number and size of the channels 36 are small, the unit time is There is a problem that a limit is imposed on the amount of processing per unit and it is not possible to increase the processing capacity. It was.

【Example】

FIG. 1 shows an embodiment of the present invention, in which a hollow container 1 and multi-tiered containers are provided inside the container 1. Each partition wall plate 2 is provided with a partition wall plate 2. Container 1 is filled with liquid such as water from the top. is discharged from the bottom, and air and other gases are pumped in from the bottom. Ru. For this reason, a liquid injection port 3 is provided at the top of the container 1 for introducing liquid. At the same time, the lower part of the container 1 has a drain port 4 for discharging liquid and a gas supply port. An air supply port 5 is provided for air injection. The partition plate 2 is inside this container 1. The container 1 is provided in multiple stages in the section to partition the interior of the container 1 into a plurality of sections in the vertical direction. this bulkhead The plate 2 serves as a flow path for the liquid introduced into the container 1, and also serves as a flow path for the liquid introduced into the container 1. This forms a gas pocket filled with liquid, and each partition plate 2 has liquid flowing downward. A liquid passage port 6 through which gas passes upward and a ventilation nozzle 7 through which gas passes upward are set in an open state. I'm being kicked. The latter ventilation nozzle 7 extends downward from the partition plate 2. It is formed. In addition, the position between the vertically adjacent partition plates 2 The ventilation nozzles 7 are formed so that they are alternately shifted. In this way, the ventilation nozzle 7 By forming a A corresponding amount of gas accumulates (dashed line in the figure) and accumulates on the bottom surface of the partition plate 2. while moving upward in the container 1 to cover the bottom surface of all partition plates 2. . On the other hand, the former liquid passage port 6 is located at a different position from the ventilation nozzle 7. It is formed on the partition plate 2. In the illustrated example, the ventilation nozzle 7 is The liquid passage port 6 is formed at the end of the partition plate 2. It is located at a position shifted from the ventilation nozzle 7. In addition, the vertically adjacent bulkhead plate Between the ports 2, the liquid passage port 6 is located at the opposite end, that is, the upper partition plate 2 is located at the right end. In this case, the lower bulkhead plate 2 is formed to be located at the left end, and this This allows the liquid to flow evenly into the container 1.

0010 In the present invention having the above configuration, gas is continuously or intermittently introduced from the air supply port 5. The liquid is fed into the container 1 to form a gas pocket on the bottom surface of each partition plate 2, and the liquid is injected.

The gas is dissolved. This downward flow of liquid flows into each partition plate 2. Since this is carried out through the formed liquid passage port 6, its fluidity is inhibited by gas. Never. Therefore, a large amount of processing can be performed per unit time. in this case, Some of the liquid passes through the vent nozzle 7, but most of the liquid passes through the liquid passage without gas obstruction. 6, the throughput increases.

[0011] FIG. 2 shows a modification of the above embodiment, in which a substantially box-shaped unit with an open lower end surface is shown. A liquid processing device is assembled by stacking knits in multiple stages. Each unit The upper surface of the knit 10 is a partition plate 2, and the partition wall plate 2 is passed through. An air nozzle 7 and a liquid passage port 6 are formed. Such a unit 10 is By changing the direction and stacking them in multiple stages so that the liquid passage port 6 is located on the opposite side. , the configuration can be similar to that of the embodiment described above. In this modified example, depending on the amount of processing This has the advantage of being practical because the number of stacked units 10 can be changed. still, 9 in the figure is a reinforcing rib provided in the middle of the liquid passage port 6.

0012 FIG. 3 shows another embodiment of the invention. In this embodiment, the liquid passage port 6 is as shown in the figure. A nozzle shape is formed at the end of the partition plate 2. Then, each bulkhead plate A separator plate 8 is vertically installed on the lower surface of the plate 2, and this separator plate 8 is attached to each partition plate 2. One or two or more ventilation nozzles are provided in each section separated by this separator 8. 7 is formed. The separator 8 is formed to be somewhat longer than the ventilation nozzle 7. The gas pocket (dashed line in the figure) formed on the bottom surface of bulkhead plate 2 is separated. It's divided. Note that the ventilation nozzles 7 are mutually shifted between the vertically adjacent partition plates 2. This is the same as in the previous embodiment. In such embodiments, isolation Since the gas pool is divided by the plate 8, one gas pool may be damaged due to vibration or tilt. Even if the gas in the reservoir escapes, the gas in other gas reservoirs can be retained. Therefore Since the liquid is in reliable contact with the gas, the liquid can be treated reliably.

[0013]

[Effect of the idea]

As explained above, the present invention has a ventilation nozzle through which gas flows and a ventilation nozzle through which liquid flows. Since the liquid passage port is provided separately, the flow of liquid is not obstructed by gas. This allows the throughput of liquid to be increased. Also, the ventilation nozzle can be used as a separator. Since the structure is designed to be more isolated, the amount of gas retained is reduced even if the container is tilted. Liquid processing can be carried out reliably without having to do anything.
