[Detailed description of the invention]

[0001]

The present invention relates to a process for absorbing a gas such as oxygen into a liquid such as water filled in a container at a high efficiency, a process for removing a gas such as carbon dioxide gas from a liquid, and other processes. The present invention relates to a multiple gas phase liquid processing apparatus to be used.

[0002]

2. Description of the Related Art A multiple gas phase type liquid processing apparatus is, for example, to efficiently dissolve oxygen in water for breeding underwater organisms, detonate sludge into activated sludge, or use aerobic and anaerobic useful microorganisms. And is used in various industrial fields.
FIG. 4 shows a conventional example of the liquid processing apparatus, which includes a container 31 and a partition plate 32 that partitions the container 31 in the vertical direction. The container 31 is filled with a liquid such as water and a gas such as air and oxygen / ozone in a contact state. A liquid injection port 33 is formed at an upper part thereof, and a liquid discharge port 33 is formed at a lower part thereof. A liquid port 34 and a gas supply port 35 are formed. The partition plates 32 are provided in a multistage manner in the container 31, and a ventilation nozzle 36 is formed in each partition plate 32. The ventilation nozzle 36 is formed so as to extend downward from the partition plate 32, and allows the gas fed into the container 31 to flow and the liquid introduced from the liquid inlet 33 to flow. The ventilation nozzles 36 are formed so as to be shifted from the partition plates 32 vertically adjacent to each other.
The gas that has passed through 6 is prevented from further rising by the partition plate 32 at the upper position. This allows
A gas reservoir (chain line in the figure) corresponding to the length of the ventilation nozzle 36 is formed below the partition plate 32. Accordingly, the liquid introduced into the container 31 flows on the multi-stage partition plate 32 while being in contact with the air reservoir, so that the liquid can be absorbed with high efficiency and then discharged from the drain port 34. . Although the drain port 34 is closed by a plug in the illustrated example, it is opened at the time of the above-described liquid processing, whereby continuous liquid processing can be performed.

[0003]

However, in the conventional structure, since the ventilation nozzle 36 serves both for the circulation of the gas and the circulation of the liquid, the size and the number of the ventilation nozzles 36 are not increased. As long as the liquid flowability is poor. That is, the liquid passes through the ventilation nozzle 36 from the upper side to the lower side, but the gas passes as a counterflow from the lower side to the upper side, and the flow of the liquid is hindered by the gas. For this reason, in the conventional structure in which the number of the ventilation nozzles 36 is small and the size is small, the processing amount per unit time is limited, and there is a problem that the processing capacity cannot be increased.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a multi-gas type liquid processing apparatus capable of performing a large amount of processing by increasing a flow rate of a liquid. It is an object.

[0005]

In order to achieve the above-mentioned object, the present invention provides a container having a drain port and a gas inlet port at the bottom and a liquid inlet at the top, and a large number of containers inside the container. A partition plate to be divided, a gas reservoir formed at a lower portion of the partition plate, and a ventilation nozzle formed to extend downward from the partition plate for ventilation of gas, and an opening in the partition plate for flowing a liquid into the container. And a liquid passage formed in the partition plate so that the ventilation nozzle and the liquid passage are located at different positions.

In the present invention, the partition plate is provided with at least one or more separators formed to be longer than the length of the ventilation nozzles extending downward, and the ventilation nozzles are provided at portions separated by the separators. It can also be provided.

[0007]

In the above construction, since the ventilation nozzle and the liquid passage are provided in the partition plate, the gas passes through the ventilation nozzle,
The liquid passes through the liquid passage and flows separately, so that the flow of the liquid is not hindered. Therefore, a large amount of liquid processing can be performed.

Further, in a configuration in which a partition plate is provided on the partition plate and a ventilation nozzle is provided for each partition plate, the gas is stored in each of the partition plates, so that even if the container is inclined, the amount of retained gas is not reduced. , Can be maintained.

[0009]

FIG. 1 shows an embodiment of the present invention, which has a hollow container 1 and partition plates 2 provided in the container 1 in multiple stages. The container 1 is filled with a liquid such as water from the upper portion and discharged from the lower portion, and is supplied with gas such as air from the lower portion. For this reason, a liquid inlet 3 for introducing a liquid is provided at the upper part of the container 1, and a liquid outlet 4 for discharging the liquid and a gas discharging port 3 are provided at the lower part of the container 1. Are provided. The partition plate 2 is provided in a multi-stage shape inside the container 1 to partition the inside of the container 1 into a plurality of parts in the vertical direction. The partition plate 2 serves as a flow passage for the liquid introduced into the container 1 and also forms a gas reservoir fed into the container 1. Each partition plate 2 has a passage through which the liquid passes downward. A liquid port 6 and a ventilation nozzle 7 through which gas passes upward are provided in an open state. The latter ventilation nozzle 7 is formed so as to extend downward from the partition plate 2. Further, between the partition plates 2 vertically adjacent to each other, the ventilation nozzles 7 are formed so that the positions thereof are alternately shifted. By forming the ventilation nozzle 7 in this manner, the gas sent from the air supply port 5 becomes a gas reservoir (a chain line in the figure) corresponding to the length of the ventilation nozzle 7 and is stored on the lower surface of the partition plate 2. While
It moves upward in the container 1 and reaches all the lower surfaces of the partition plates 2. On the other hand, the former liquid passage 6 is formed in each partition plate 2 so as to be located at a position different from such a ventilation nozzle 7. In the illustrated example, the ventilation nozzle 7 is formed at the central portion of the partition plate 7, while the liquid passage 6 is formed at the end of the partition plate 2 and is located at a position shifted from the ventilation nozzle 7. Also, between the partition plates 2 vertically adjacent to each other, the liquid inlet 6 is formed at the opposite end, that is, when the upper partition plate 2 is at the right end, the lower partition plate 2 is formed at the left end. This allows the liquid to flow evenly into the container 1.

In the present invention having the above structure, gas is continuously or intermittently fed into the container 1 from the air supply port 5 to form a gas reservoir on the lower surface of each partition plate 2.
When the liquid is introduced from the liquid inlet 3, the liquid flows along the upper partition plate 2, flows from the liquid inlet 6 to the lower partition plate 2, and comes into contact with the gas reservoir during this flow to generate gas. Dissolution takes place. The downward flow of the liquid is performed by the liquid passage ports 6 formed in the partition plates 2, so that the gas does not hinder the fluidity. Therefore, a large amount of processing can be performed in a unit time. In this case, a part of the liquid passes through the ventilation nozzle 7, but most of the liquid flows through the liquid passage 6 without gas interference, so that the throughput increases.

FIG. 2 shows a modification of the above-described embodiment. The liquid processing apparatus is assembled by stacking substantially box-shaped units each having a lower end surface opened in multiple stages.
The upper surface of each unit 10 is a partition plate 2, and a ventilation nozzle 7 and a liquid passage 6 are formed in the partition plate 2. Such a unit 10 can have the same configuration as that of the above-described embodiment by changing the direction so that the liquid passage 6 is located on the opposite side and stacking the units in a multi-stage manner. In this modified example, there is an advantage that the number of stacks of the unit 10 can be changed according to the processing amount, which is practical. In the drawing, reference numeral 9 denotes a reinforcing rib provided in the middle of the liquid passage 6.

FIG. 3 shows another embodiment of the present invention. In this embodiment, the liquid passage 6 is formed in a nozzle shape at the end of the partition plate 2 as shown in the figure. Separator plates 8 are vertically provided on the lower surface of each partition plate 2, and one or two or more separator plates 8 are provided on each partition plate 2, and a ventilation nozzle is provided for each part partitioned by the separator plates 8. 7 are formed. The separator 8 is formed to be slightly longer than the ventilation nozzle 7 and divides a gas reservoir (a chain line in the figure) formed on the lower surface of the partition plate 2. It is to be noted that the ventilation nozzles 7 are provided so as to be displaced from each other between the vertically adjacent partition plates 2 in the same manner as in the above embodiment. In such an embodiment, since the gas reservoir is divided by the separator 8, even if the gas in one gas reservoir escapes due to vibration, inclination, or the like, the gas in another gas reservoir can be retained. Therefore, the liquid is reliably brought into contact with the gas, so that the liquid processing can be reliably performed.

[0013]

As described above, in the present invention, the ventilation nozzle through which the gas flows and the liquid passage through which the liquid flows are separately provided, so that the flow of the liquid is not hindered by the gas. As a result, the throughput of the liquid can be increased. Further, since the ventilation nozzle is configured to be isolated by the separator plate, the liquid treatment can be performed reliably without reducing the amount of gas to be stored even if the container is inclined.
