DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a fluid adsorption / separation system according to the present invention will be described below. In the following embodiments, a gas purification system that mainly removes harmful substances such as hydrogen chloride and dioxin from various kinds of exhaust gas will be described.

First Embodiment (FIG. 1) FIG. 1 is a system diagram showing a gas purification system according to a first embodiment of the present invention.

In this embodiment, as shown in FIG. 1, an exhaust gas generating source 1 such as a refuse incinerator is installed at the first stage, and a gas flow path 2 for flowing exhaust gas a is connected to the exhaust gas generating source 1. I have. Exhaust gas a as a fluid to be treated in the present embodiment continuously flows in one direction through the inside of the gas flow path 2 as indicated by an arrow.

An auxiliary agent adding means 3 is connected to a predetermined position in the gas flow path 2. The auxiliary agent adding means 3 includes a new auxiliary agent storage 4 for storing a new auxiliary agent b, and an auxiliary addition channel 5 connecting the new auxiliary agent storage 4 and the gas channel 2. The auxiliary agent b is continuously added to the exhaust gas a flowing through the flow path 2.

The auxiliary agent b is a fine powder made of, for example, activated carbon or slaked lime, and adsorbs harmful gas components such as hydrogen chloride and dioxin contained in the exhaust gas a.

On the downstream side of the auxiliary agent adding means 3 in the gas flow path 2,
A filtration device 6 is provided as auxiliary agent capturing means. The filtering device 6 has a configuration in which, for example, the auxiliary agent b is dropped to the bottom after being captured.

On the downstream side of the filtration device 6, a purified exhaust gas channel 7 for discharging the filtered exhaust gas c is provided. It is to be released.

On the bottom side of the filtration device 6, an auxiliary re-adding means 8 for recovering the used auxiliary b 1 captured here and adding the remaining auxiliary b 1 to the gas channel 2 again.
Is provided.

Auxiliary agent re-adding means 8 includes a used auxiliary agent remover 9 serving as an auxiliary agent removing means for extracting the used auxiliary agent b1 from the filtration device 6, and an adsorption for discriminating the adsorption capacity of the extracted auxiliary agent b1. The apparatus includes a capacity determining means 10 and a flow switch 11 as a flow switching means for switching the flow direction of the auxiliary b1 between the re-addition side and the discharge side in accordance with the determined adsorbing ability of the auxiliary b1.

The adsorbing ability judging means 10 detects the auxiliary agent b
A measuring means 12 for measuring the content of the adsorbed substance to the adsorbent 1 and the adsorption capacity remaining in the adjuvant b1 based on the measured content of the substance. Calculation means 13 for setting.

The flow switch 11 also includes a used auxiliary agent discharge path 14 for discharging the used auxiliary agent b2 having no remaining adsorbing ability, and a use agent for recovering the auxiliary agent b3 having the remaining adsorbing capacity. The used auxiliary agent recovery path 15 is connected.

The used auxiliary agent recovery passage 15 has a used auxiliary agent b
A used auxiliary agent storage 16 for temporarily storing the used auxiliary agent b3 is provided in the used auxiliary agent storage device 16 for re-adding the used auxiliary agent b3 to the gas flow path 2. The re-addition channel 17 is connected. The connection position of the used auxiliary agent re-addition channel 17 to the gas channel 2 is upstream of the connection position of the auxiliary agent addition channel 5 for supplying the new auxiliary agent b from the new auxiliary agent storage 4. It has been. In addition, the used auxiliary agent removal device 9 described above, the used auxiliary agent discharge passage 14, the used auxiliary agent collection passage 1
5. Although not shown, a fluid supply pump and the like are provided in the used auxiliary agent re-adding channel 17 and the like. Further, the filter device 6 is provided with an auxiliary agent releasing means for releasing the auxiliary agent b from the filter by vibration, backwashing or the like.

Next, the operation will be described.

At the same time as the exhaust gas a generated by the exhaust gas generation source 1 continuously flows through the gas flow path 2, the gas flow path 2 is filled with a new product through a new auxiliary storage 4 and an auxiliary addition flow path 5. Auxiliary b is supplied. When the exhaust gas a flowing through the gas flow path 2 contains target substances to be removed such as hydrogen chloride and dioxin, these target substances are adsorbed by the auxiliary agent b, and the auxiliary Captured with.

Spent auxiliary agent b captured by filtration device 6
Is continuously or periodically removed from the filtration device 6 and is taken out through the used auxiliary agent take-out device 9. During the removal, the auxiliary b
Is measured, and the data is taken into the calculating means 13 to determine the adsorbing ability of the assistant b for the target substance.

As described above, the amount of the target substance adsorbed on the auxiliary agent b takes various values depending on the content in the exhaust gas a, the flow rate of the exhaust gas a, and the amount of the new auxiliary agent b added. Further, it also varies variously depending on the accumulation position, the residence time, and the like in the filtration device 6. Conventionally, the used auxiliary agent b is discarded without sufficiently considering these factors.

The point that the inventors have paid particular attention to is the relationship between the accumulation position of the auxiliary agent b in the filtration device 6 and the residence time. Auxiliary b at a certain width along the flow direction of exhaust gas a
In the state where is accumulated in the filtration device 6, the auxiliary substance b that is retained on the upstream side of the exhaust gas a contains a larger amount of the target substance, and the adsorption capacity is significantly reduced. This is because a new target substance always flows into the filtration device 6. Therefore, due to the opposite phenomenon, the auxiliary agent b that stays downstream of the exhaust gas a has a higher residual ratio of the adsorption capacity.

Also, based on the general flow distribution, the auxiliary agent b disposed on the center side of the flow path has a reduced residual adsorption capacity due to many fluid contacts, and the auxiliary agent b disposed on the peripheral side of the flow path Conversely, b tends to have a higher residual adsorption capacity. This event was actually confirmed by various experiments.

In the present embodiment, based on such a tendency, the auxiliary agent b in the filtration device 6 can be separated and taken out from each retention position. Further, it is also possible to select taking out from each position with a certain time difference. In the present embodiment, such selective removal of the used auxiliary agent b is performed by the used auxiliary agent removing device 9.

As a result, the remaining adsorbing capacity of the used auxiliary agent b passing through the measuring means 12 changes variously in accordance with the state of removal, and this is discriminated by the calculating means 13 and the flow switch 11 switches the flow path. That's why.

When the residual adsorbing ability of the used auxiliary agent b is low, the auxiliary agent b is caused to flow to the used auxiliary agent discharge path 14 side by switching the flow path of the flow switching device 11 to be disposed. Conversely, when the residual adsorbing capacity of the auxiliary agent b is high, the auxiliary agent b is caused to flow toward the used auxiliary agent recovery path 15 by switching the flow path of the flow switching device 11 and once stored in the used auxiliary agent storage 16. Store.

Various types such as a hopper type can be applied to the spent auxiliary agent storage 16, and continuous re-removal and supply can be performed by installing a feeder or the like. In the present embodiment, continuous supply to the used auxiliary agent re-addition channel 17 is performed.

As described above, since the used auxiliary agent re-addition channel 17 is connected to the gas channel 2 on the upstream side of the auxiliary agent addition channel 5 of the new auxiliary agent storage 4, it is always used. The auxiliary agent b comes into contact with the exhaust gas a flowing through the gas passage 2 before the new auxiliary agent b. And exhaust gas a
The target substance to be adsorbed contained in is adsorbed according to the remaining adsorption capacity. As a result, when the new exhaust gas a is captured by the filtration device 6, the residual ratio of the adsorption capacity is significantly higher than in the conventional system.

By circulating the auxiliary b in the system in this way, the auxiliary b can be used very efficiently while reliably discarding or re-adding the used auxiliary b.

The second spent auxiliary agent re-adding channels 17a and 17b are divided in parallel. Then, the re-adding position of the leading end of each path to the gas flow path 2 is made different from the upstream side to the downstream side in the flow direction of the exhaust gas a.

Routes 5a, 16a, 17a and 15b, 16b, 17
The auxiliary agent b supplied to the path (b) has different settings for the remaining adsorption capacity. And gas flow path 2
The adsorbing capacity of the auxiliary b re-added relatively upstream of the
It is set to be higher than the adsorbing ability of the auxiliary b re-added relatively downstream of the gas flow path 2.

According to the system of the second embodiment, the operation described in the first embodiment is performed in the gas flow path 2 in a finely controlled state.

Therefore, the substance to be adsorbed contained in the exhaust gas a is always contacted and adsorbed in order from the auxiliary agent b having the lowest residual adsorption capacity, which is always re-added to the uppermost stream side of the gas flow path 2.
