The adsorbent bodies 15 of the adsorbent 5 are arranged at substantially equal intervals in the circumferential direction of the rotation center 36 and are detachably supported on the inner bottom portion of the support body 38 of the support 31.

In plan view of the oil adsorbing device 1 (FIG. 3), assuming that the plurality of adsorbents 5 are made counterclockwise into first to fourth adsorbents 5 (A to D), the pipes are Reference numeral 8 denotes an inlet portion 3 corresponding to the adsorbent body 15 of the first adsorbent 5 (A).
The first pipe 4 for connecting the discharge side of the pressure pump 9 to 2
4 and the second pipe for communicating the outlet portion 33 corresponding to the adsorbent body 15 of the first adsorbent 5 (A) with the inlet portion 32 corresponding to the adsorbent body 15 of the second adsorbent 5 (B) 45
And the outlet portion 33 corresponding to the adsorbent body 15 of the second adsorbent 5 (B) is attached to the adsorbent body 1 of the third adsorbent 5 (C).
The third pipe 46 communicating with the inlet portion 32 corresponding to 5 is provided, and the upstream end of the other pipe 10 is connected to the outlet portion 33 corresponding to the adsorbent body 15 of the third adsorbent 5 (C). ing.

At the portion of the cover body 28 above the fourth adsorbent body 5 (D), the fourth adsorbent body 5 (D) is placed inside the support body 38 of the support body 31 from above. An inlet / outlet port 48 is formed so that it can be inserted and removed freely.

By operating the fixing tool 41 of the support 31,
Support body 38 of support 31 for cover body 28
Is released (dashed-dotted line in FIGS. 4 and 5), the support body 38 is moved slightly downward while counteracting the urging force of the spring 40, and then, together with the support body 38 of the support body 31, When the adsorbent body 15 of each adsorbent 5 is rotated about the rotation center 36 by a predetermined angle (90 °), the inlet portion 32 and the outlet portion corresponding to the arbitrary adsorbent body 15 of the adsorbent 5 are provided. 33, the adsorbent body 15 of another adsorbent 5 can be used instead of the adsorbent body 15 of this adsorbent 5.

When the oil adsorption device 1 is used, the turbid water 2 is applied to each adsorbent 5 by the pressure pump 9.
To supply. Then, the turbid water 2 flows in the following order, and the oil component turbid in the turbid water 2 is adsorbed by the oil adsorbent 23 of the adsorbent body 15 of each of the adsorbents 5 and thus the purified water 3 It is said that

That is, the turbid water 2 discharged from the pressure-feeding pump 9 has the inlet 32, the through hole 27, the space 21, the adsorbent body 1 corresponding to the first pipe 44 → the first adsorbent 5 (A).
5, and the outlet part 33 → second pipe 45 → second adsorbent 5
Inlet 32, through hole 27, space 21, corresponding to (B)
Adsorbent body 15, and outlet section 33 → third pipe 46 → inlet section 32 corresponding to third adsorbent 5 (C), through hole 27,
The space 21, the adsorbent body 15, and the outlet portion 33 and the other pipe 10 flow in this order.

More specifically, as described above, the turbid water 2
However, when the adsorbent body 15 of each of the adsorbents 5 flows so as to penetrate, first, the turbid water 2 is added to the adsorbent body 1 as described above.
After being made to flow through the through hole 27 from the one end 17 side of the No. 5 toward the other end 19 side, it is reversed in the space 21 and the other end 19 side of the adsorbent body 15 to the one end 17 side. Through the spacer 25 and flows through the adsorbent body 15 in the axial direction.

In this case, the turbid water 2 flows through the spacer 25 in the adsorbent body 15, and at this time,
The oil component that is turbid in the turbid water 2 is successively deposited on the outer surface of the oil adsorbent 23, and is coalesced with each other to grow into larger oil droplets, thereby being adsorbed on the oil adsorbent 23. Therefore, the purified water 3 is finally generated and discharged through the other pipe 10.

When the oil adsorbent 23 of the adsorbent body 15 of each adsorbent 5 is adsorbed by the oil adsorbent 23 as the oil adsorber 1 is used, the degree of clogging of each oil adsorbent 23 becomes more severe. However, the degree of this clogging is detected by a pressure gauge (not shown) provided in the flow path of the turbid water 2 such as the first pipe 44.

As the use of the oil adsorbing device 1 progresses, the oil adsorbent 23 of the adsorbent body 15 of the adsorbent 5 on the upstream side of the first to third adsorbents 5 (A to C) becomes More severe clogging occurs and it becomes difficult to continue using the oil adsorption device 1.

Therefore, the use of the oil adsorbing device 1 is stopped, and the adsorbent body 15 of the fourth adsorbent 5 (D) is replaced with a new one.
Is operated to release the fixation of the support body 38 of the support 31 to the cover body 28. Next, the support body 38 is moved slightly downward while counteracting the biasing force of the spring 40, and in this state, the support body 3 of the support 31 is moved.
8, the adsorbent body 15 of each adsorbent 5 is rotated clockwise about the rotation center 36 by a predetermined angle (90 °), and the positions of the first to fourth adsorbents 5 (A to D) are changed. The rotation center 36 is changed one by one.

Then, one end portion 17 of each of the adsorbent bodies 15 of the first to fourth adsorbent bodies 5 is fixed to the lower surface of the cover body 28 by the support body 31.

As described above, the adsorbent body 15 of the adsorbent 5 having the highest degree of clogging is positioned so as to face the inlet / outlet port 48. Then, the adsorbent 5 can be exchanged with another new adsorbent 5 through the inlet / outlet port 48. On the other hand, among the first to third adsorbents 5 (A to C) that have been clogged due to the adsorption of oil, the adsorbents 5 other than the most severe one described above are The turbid water 2 is sequentially positioned on the upstream side of the flow, and the new adsorbent 5 is positioned on the most downstream side.

Then, the turbid water 2 sequentially flows from the adsorbent 5 having a high degree of clogging to the adsorbent 5 having a low degree of clogging, and finally flows into the new adsorbent 5. Cleaner purified water 3 is generated.

The pure water purification device 4 is the oil adsorption device 1 described above.
The water pump 49 that sucks in the purified water 3 discharged from the other pipe 10 on the downstream side, and discharges it at a high pressure, and the purified water 3 discharged from the water pump 49 is further purified to be pure water.

A membrane), whereby most of the substances in the ion low molecular weight region remaining in the purified water 3 discharged from the other pipe 10 of the oil adsorbing device 1 are removed to be pure water. The purified water 3a is purified.

The water quality sensor 51 constantly detects the condition of the quality of the purified water 3a purified as described above, and although not described in detail, when the water quality level is lower than a predetermined value, it is detected by the detection signal. The reverse osmosis membrane device 50 is automatically flushed so that the purified water 3a having a desired water quality level is automatically and continuously purified.

According to the above structure, the oil adsorbent 23 which is in the form of a sheet and is wound around the shaft center 14, and the shaft center 1
Both of the oil adsorbents 23 that are adjacent to each other in the direction orthogonal to 4
The adsorbent main body 15 having a liquid-permeable spacer 25 interposed between the adsorbent main body 15 and the adsorbent main body 15 is made to flow through the spacer 25 in the axial direction of the adsorbent main body 15. is there.

For this reason, the turbid water 2 flows through the spacer 25 and along substantially the entire front and back surfaces of the oil adsorbent 23 of the adsorbent body 15 of the adsorbent 5, so that the turbid water 2 The oil that is turbid with is adsorbed on almost the entire outer surface of the oil adsorbent 23.

Moreover, the spacer 25 through which the turbid water 2 passes
Since it has liquid permeability and is unlikely to be clogged, the turbid water 2 flows through the spacer 25 and flows along substantially the entire outer surface of the oil adsorbent 23 for a long period of time.

Therefore, the oil adsorbing action of the oil adsorbent 23 of the oil adsorbing device 1 can be favorably maintained for a longer period of time.

In the above case, the oil adsorbent 23 and the spacer 25
Are formed into a sheet shape, and are wound around the shaft center 14.

Therefore, when the adsorbent body 15 is formed, first, the oil adsorbent 23 and the spacer 25 are superposed on each other to form the superposed body, and then the superposed body is formed on the axial center. The adsorbent body 15 can be easily formed by simply winding around the adsorbent body 14.

Further, as described above, the through hole 27 penetrating the adsorbent body 15 in its axial direction is formed substantially on the axial center 14, and the turbid water 2 is fed to the adsorbent body 15 at one axial end thereof. The through hole 2 from the side of the portion 17 toward the side of the other end 19
After flowing through 7, the turbid water 2 is caused to flow through the adsorbent body 15 from the other end 19 side of the adsorbent body 15 toward the one end 17 side.

Therefore, in the oil adsorbing device 1, normally, the pipe 8 for supplying the turbid water 2 toward the oil adsorbing material 23 of the adsorbent body 15 and the oil after the oil is removed by the oil adsorbing material 23. Other pipes 10 for discharging the purified water 3 are provided, but in this case, the pipes 8 and 10 can be concentrated on the one end portion 17 side of the adsorbent body 15.

Therefore, for example, the oil adsorbing device 1 becomes compact as compared with the case where the respective pipes 8 and 10 are simply arranged on the oil adsorbing material 23 of the adsorbent body 15 on the downstream side. The occupied space can be made smaller.

Further, as described above, the shaft main body 14 extends substantially vertically and the one end 17 is the upper end, while the other end 19 is the lower end, and the adsorbent body 15 is provided.
One end 17 of the adsorbent body 15 is supported by the fixed side 6.
A cover body 28 for covering the above from above and the adsorbent body 1
5 is detachably supported and one end 17 of the adsorbent body 15 is detachably fixed to the lower surface of the cover body 28; and the outside of the cover body 28 is formed on the cover body 28. It has an inlet portion 32 that communicates with the upper end of the through hole 27, and an outlet portion 33 that is formed in the cover body 28 and that communicates the one end 17 side of the adsorbent body 15 with the outside of the cover body 28.

Therefore, when the oil adsorbent 23 of the adsorbent body 15 which is clogged due to the use of the oil adsorbing device 1 is to be replaced with a slightly clogged oil adsorbent 23 or a new one, as described above. , The fixing member 41 of the support 31 is operated to release the fixing of the support body 38 to the cover body 28, and the oil adsorbent 2 of the adsorbent body 15 in which clogging has occurred is released.
3 may be removed from the cover body 28, and instead of this, a lightly clogged one or a new one may be fixed to the cover body 28.

Therefore, the replacement work of the oil adsorbent 23 of the adsorbent body 15 in the oil adsorbing device 1 is performed by the pipe 8 to the inlet portion 32 and the outlet portion 33 formed in the cover body 28.
Can be performed without desorption, that is, the adsorbent body 1
The oil adsorbent 23 of No. 5 can be easily replaced.

Further, as described above, the support 31 is pivotally supported on the fixed side 6 so as to be rotatable about the rotation center 36 extending in the substantially vertical direction, and the support 31 is moved in the circumferential direction of the rotation center 36. By arranging a plurality of the adsorbent bodies 15 so that the adsorbent bodies 15 are detachably supported by the support body 31, and each adsorbent body 15 is rotated around the rotation center 36 together with the support body 31, a certain adsorbent body is obtained. The inlet 32 corresponding to 15
Instead of the adsorbent body 15 for the outlet part 33 and the outlet part 33,
The other adsorbent body 15 is made compatible.

For this reason, when the turbid water 2 is to be made to flow sequentially according to the degree of clogging of the oil adsorbent 23 of the plurality of adsorbent bodies 15, the flow order of the turbid water 2 is changed. If desired, as described above, the adsorbent body 15 may be replaced by another adsorbent body 15 in place of the adsorbent body 15 with respect to the inlet portion 32 and the outlet portion 33. This is achieved by the simple operation of rotating the support body 38 of the support 31 about the rotation center 36 as described above.

Therefore, the flow order of the turbid water 2 can be changed without changing the route of the pipe 8 to the inlet portion 32 and the outlet portion 33 formed in the cover body 28.
That is, the operation of changing the flow order of the turbid water 2 can be easily performed.

Further, as described above, the pure water purifying device 4 is connected in series on the downstream side of the oil adsorbing device 1. Therefore, the turbid water 2 is sufficiently purified in advance by the oil adsorbing device 1. Therefore, the load on the pure water purification device 4 is sufficiently reduced. Therefore, according to this pure water purification device 4, the purified water 3a of pure water is further purified, and the maintenance and inspection work for the pure water purification device 4 is reduced, and this work can be facilitated. .

Although the above is based on the illustrated example, in the above structure, the oil adsorbent 23 is formed into a plurality of cylindrical shapes arranged on the shaft center 14 and fitted with each other, and the spacer 25 is also arranged on the shaft center 14.

Therefore, when the oil adsorbent of the adsorbent body that has been clogged due to the use of the oil adsorbing device is to be replaced with a slightly clogged oil adsorbent or a new one, the support is operated. The oil adsorbent of the adsorbent body that has been clogged may be removed from the cover body, and instead of this, a slightly clogged one or a new one may be fixed to the cover body.

Therefore, the operation of exchanging the oil adsorbent of the adsorbent body in the oil adsorbing device can be carried out without detaching the pipe to the inlet or outlet formed in the cover, that is, the adsorbent. It is easy to replace the oil adsorbent on the main body.

According to a fifth aspect of the present invention, the support is pivotally supported on the fixed side so as to be rotatable about a rotation center extending in a substantially vertical direction, and a plurality of the suction members are circumferentially arranged around the rotation center. Place the body body and make it detachably supported on the support,
By rotating each adsorbent body around the rotation center together with this support, the adsorbent body is replaced by another adsorbent body for the inlet portion and the outlet portion corresponding to a certain adsorbent body. The main body is adapted.

Therefore, when it is desired to change the flow order of the turbid water, for example, when the turbid water is to be made to flow sequentially according to the degree of clogging of each of the oil adsorbents of the plurality of adsorbent bodies, As described above, with respect to the inlet part and the outlet part corresponding to a certain adsorbent body, instead of this adsorbent body, another adsorbent body may be made to correspond, which is
This is achieved by the simple operation of rotating the support body of the support around the rotation center as described above.

Therefore, the order of the flow of the turbid water can be changed without changing the path of the pipe to the inlet and the outlet formed in the cover, that is, the order of the flow of the turbid water. The conversion work of can be done easily.
