Abstract

A foreign matter removing device is a device for removing foreign particles from a fluid to be treated that contains foreign particles. The foreign matter removal device includes a container having an inlet, an adsorption outlet, and a desorption outlet, and a plurality of adsorbents contained in the container for adsorbing and desorbing foreign particles. The detachment outlet is formed above the inlet or the outlet, which is the end of the pipe extending from the inlet into the container. The plurality of adsorbents remove foreign particles from the fluid to be treated by adsorbing foreign particles contained in the fluid flowing from the inlet or the outlet toward the adsorption outlet, and desorb from the inlet or the outlet. Adsorbed foreign particles are desorbed by flowing in the storage container with the cleaning fluid flowing toward the discharge port. The detached foreign particles are discharged from the desorption outlet.

Description

TECHNICAL FIELD The present disclosure relates to a foreign matter removing device, and more particularly to a foreign matter removing device that removes foreign particles in a liquid by adsorbing and desorbing foreign particles, which are particles to be separated in the liquid, with an adsorbent.

2. Description of the Related Art Conventionally, there is a foreign matter removing device that removes foreign matter particles contained in a liquid fluid to be treated (see, for example, Patent Document 1). In the foreign matter removing device of Patent Document 1, a plurality of granular filter media, a first filter bed, and a second filter bed are arranged in a container having an inlet on the lower surface and an outlet on the upper surface. there is The first filter bed and the second filter bed are plate-shaped mesh members that allow the fluid to be treated to pass through, and are arranged with a vertical separation, and in the space between the first and second filter beds, A plurality of filter media are arranged so as to be able to flow. The first filter bed is arranged above the plurality of filter media and holds the filter media when foreign particles are filtered by the filter media. The second filter bed is arranged at the inflow port and prevents outflow of the filter material during backwashing, which will be described later.

In the foreign matter removing apparatus having the above configuration, the fluid to be treated is caused to flow upward from the inlet toward the outlet during filtration for removing foreign particles from the fluid to be treated. As a result, the plurality of filter media are gathered upward by the flow of the fluid to be treated and deposited on the lower surface side of the first filter bed to form a deposited filter layer. When the fluid to be treated flows from the inflow port toward the outflow port during filtration, the foreign matter removing device captures and removes the foreign matter particles with the accumulated filtration layer. On the other hand, when the foreign particles are detached from the filter medium, the backwash water is caused to flow in the opposite direction to that during filtration, that is, from the outflow port to the inflow port from above to below. As a result, the dynamic pressure of the backwash water acts on the sedimentary filtration layer, and the plurality of filter media constituting the sedimentary filtration layer flow apart in the space between the first filter bed and the second filter bed. As a result, foreign particles trapped in the sedimentary filtration layer are desorbed from the filter material, floated in the space, and discharged to the outside through the second filter bed together with the backwash water.

JP-A-08-299713

In the configuration of Patent Literature 1, during desorption, backwash water is caused to flow from top to bottom, which is the reverse of that during filtration. Due to the flow of the backwash water, the filter media, which have once been disassembled, gradually accumulate on the upper surface of the second filter bed, clogging the inflow port, and preventing foreign particles from being discharged. As described above, in the configuration of Patent Document 1, there is a problem that the ability to discharge foreign particles at the time of desorption gradually decreases.

The present disclosure has been made to solve the above problems, and an object of the present disclosure is to provide a foreign matter removing device capable of stably maintaining the ability to discharge foreign matter particles during detachment.

A foreign matter removing device according to the present disclosure is a foreign matter removing device for removing foreign particles from a fluid to be treated containing foreign particles, and comprises a container having an inflow port, an adsorption outflow port, and a desorption discharge port, and A plurality of adsorbents that are accommodated to adsorb and desorb foreign particles, and a flow prevention filter that is movable in a container and supported to be vibrated or rotatable to prevent the flow of the plurality of adsorbents. The outlet for adsorption is formed above the inlet or the outlet, which is the end of a pipe extending from the inlet into the container. Foreign particles are removed from the fluid to be treated by adsorbing foreign particles contained in the fluid to be treated flowing toward the outlet. By doing so, the adsorbed foreign particles are desorbed, the desorbed foreign particles are discharged from the desorption discharge port, and the flow prevention filter directs the fluid to be treated to the plurality of adsorbents at the time of adsorption when the fluid to be treated flows through the container. It moves and presses the plurality of adsorbents against the inner surface of the container to prevent the flow of the plurality of adsorbents, and moves while vibrating or rotating when moving toward the plurality of adsorbents . .

According to the present disclosure, since the flow direction of the cleaning fluid in the housing container during desorption is set from the bottom to the top, the adsorption material does not accumulate in the discharge port for desorption and clogs the discharge port for desorption. can stably maintain the ability to discharge foreign particles during desorption.

Embodiment 1.
A foreign matter removing apparatus 100 according to Embodiment 1 will be described with reference to FIGS. 1 to 5. FIG.

FIG. 1 is a schematic diagram of a foreign matter removing device 100 according to Embodiment 1. FIG.
The foreign matter removing device 100 is a device for removing foreign particles 11 to be separated from a liquid fluid flowing into the container 1 and containing the foreign particles 11 (hereinafter referred to as a fluid to be treated). A foreign matter removing apparatus 100 includes a container 1 and a plurality of adsorbents 10 that are contained in the container 1 and that adsorb and desorb foreign particles 11 .

The adsorbent 10 is, for example, glass beads. The adsorbent 10 may be particles of organic compounds such as plastic particles, particles of inorganic compounds such as metal particles or ceramic particles, or particles of organic and inorganic compounds such as organometallic structures. The surface of the adsorbent 10 may be charged so that the adsorption efficiency is improved by applying an electrostatic attractive force in addition to the adsorption force. Specifically, the adsorbent 10 may have a structure in which the surfaces of the glass beads are modified so that the surfaces of the glass beads have an electric charge opposite to the surface electric charge of the foreign particles 11 to be separated. As a result, the adsorbent 10 can adsorb the foreign particles 11 even by electrostatic attraction, and the adsorption efficiency can be improved. Also, the adsorbent 10 is configured to have a particle diameter larger than that of the foreign matter particles 11 .

A plurality of adsorbents 10 are housed in the housing container 1 . The adsorbent 10 is deposited within the container 1 to form an adsorbent assembly 12 . The adsorbent 10 is filled in the storage container 1 in an amount that does not fill up the internal space of the storage container 1 . As a result, a space other than the adsorbent assembly 12 is formed in the internal space of the container 1 . The reason why the storage container 1 is not filled with the adsorbent 10 in this manner is to secure a space for the adsorbent 10 to flow during desorption, as will be described in detail below.

The container 1 is configured in a rectangular parallelepiped shape having an upper surface, a lower surface and four side surfaces. The storage container 1 is not limited to a rectangular parallelepiped shape, and may have another shape such as a cylindrical shape. The container 1 is formed with an inlet 2 , an adsorption outlet 3 and a desorption outlet 4 . The inlet 2 is an inlet for allowing the fluid to be treated or the cleaning fluid to flow into the container 1 , and is formed in the lower portion of the side surface of the container 1 . The fluid to be treated flows into the inlet 2 during adsorption, and the cleaning fluid flows into it during desorption. Here, the cleaning fluid is a fluid that does not contain the foreign particles 11 and is a fluid for desorbing the foreign particles 11 from the adsorbent 10 .

The adsorption outflow port 3 is an outlet through which the fluid to be treated from which the foreign particles 11 have been removed during adsorption flows out, and is formed on the upper surface of the container 1 . The desorption discharge port 4 is an outlet for discharging the cleaning fluid containing the foreign particles 11 desorbed from the surface of the adsorbent 10 during desorption from the storage container 1 , and is formed in the upper part of the side surface of the storage container 1 . . The discharge port 4 for desorption is formed above at least the inlet port 2 in order to form a flow of cleaning fluid from bottom to top during desorption. In the following, when the fluid to be processed and the cleaning fluid are not distinguished, they are collectively referred to as fluid.

An outflow prevention filter 5 for preventing the adsorbent 10 from flowing out of the container 1 is installed at each of the inlet 2 , the adsorption outlet 3 , and the desorption outlet 4 . The outflow prevention filter 5 is composed of a mesh plate-like member that allows fluid to pass through. The mesh size of the outflow prevention filter 5 is such that the adsorbent 10 does not pass through but the foreign particles 11 pass through. This is because if the mesh size of the outflow prevention filter 5 is smaller than the foreign particles 11, the foreign particles 11 may accumulate on the outflow prevention filter 5 and cause clogging.

The foreign matter removing apparatus 100 further includes a first flow rate control device 6 that controls the flow rate of fluid flowing into the container 1 . The first flow control device 6 is arranged in the pipe that constitutes the inlet 2 . The foreign matter removing apparatus 100 also includes a second flow control device 7 for controlling the flow rate of the fluid to be treated flowing out of the container 1 and a third flow control device 8 for controlling the flow rate of the cleaning fluid flowing out from the container 1. It has The second flow control device 7 is arranged in the pipe forming the adsorption outlet 3 , and the third flow control device 8 is arranged in the pipe forming the desorption outlet 4 . The first flow control device 6, the second flow control device 7, and the third flow control device 8 may be manually operated, or may be automatically operated by a control device (not shown). The first flow control device 6, the second flow control device 7 and the third flow control device 8 are composed of, for example, expansion valves.

The foreign matter removing device 100 alternately and repeatedly adsorbs and desorbs the foreign matter particles 11 . Adsorption and desorption will be described below.

(adsorption)
2A and 2B are diagrams for explaining the operation of the foreign matter removing device 100 according to the first embodiment during adsorption.
During adsorption, the first flow control device 6 and the second flow control device 7 are opened to open the inlet 2 and the adsorption outlet 3 . Also, the third flow rate control device 8 is closed and the discharge port 4 for desorption is closed. During adsorption, the fluid to be treated flows into the container 1 through the inflow port 2 and flows out of the container 1 through the adsorption outflow port 3 as indicated by the white arrow. The foreign particles 11 are removed from the fluid to be treated that has flowed into the container 1 from the inlet 2 as the foreign particles 11 are adsorbed by the adsorbent 10 when passing through the adsorbent assembly 12 . Then, the fluid to be treated from which the foreign particles 11 have been removed flows out from the adsorption outlet 3 .

(Detachment)
3A and 3B are diagrams for explaining the operation of the foreign matter removing device 100 according to the first embodiment when it is attached and detached.
During attachment/detachment, the first flow rate control device 6 and the third flow rate control device 8 are opened to open the inflow port 2 and the detachment discharge port 4 . In addition, the second flow rate control device 7 is closed to close the adsorption outflow port 3 . During attachment/detachment, the cleaning fluid flows into the container 1 from the inlet 2 and is discharged to the outside of the container 1 from the discharge port 4 for attachment/detachment, as indicated by the white arrow.

The flow rate of the cleaning fluid flowing into the container 1 at the time of desorption is set to a flow rate at which the adsorbent assembly 12 is decomposed by the dynamic pressure of the cleaning fluid and the individual adsorbents 10 can flow within the container 1. It is Since this flow rate varies depending on the weight of the adsorbent 10 and the viscosity of the cleaning fluid, it can be determined by simulation, experiment, or the like. The adjustment of the flow rate may be controlled by the first flow control device 6 and the third flow control device 8, or may be controlled by a water supply device such as a pump provided upstream of the inlet 2. FIG.

When the cleaning fluid at the above flow rate flows into the storage container 1 from the inlet 2, the adsorbent assembly 12 is decomposed as shown in FIG. flows in the container 1 as shown in . As a result, collisions between the adsorbents 10 are repeated within the container 1, and the foreign particles 11 are desorbed from the surface of the adsorbent, thereby regenerating the adsorption force of the adsorbent 10. FIG. The foreign particles 11 desorbed from the adsorbent surface are discharged from the desorption discharge port 4 along with the flow of the cleaning fluid.

Here, since the flow of the cleaning fluid at the time of desorption in the storage container 1 is a flow from the bottom to the top, the adsorbent 10 does not accumulate on the desorption discharge port 4 and block the desorption discharge port 4. . Therefore, the foreign matter removing device 100 can stably maintain the ability to discharge the foreign matter particles 11 from the start to the end of desorption.

After finishing the above desorption, when switching to adsorption, the foreign matter removing apparatus 100 controls the flow rate of the cleaning fluid or the fluid to be treated flowing into the container 1 so that the adsorbent 10 settles to the bottom of the container 1. Let it pile up. After the adsorbent assembly 12 is formed, adsorption is started.

In the above description, an example was described in which the flow rate of the cleaning fluid in the container 1 during desorption was controlled using two flow control devices, the first flow control device 6 and the third flow control device 8. Only one of the first flow control device 6 and the third flow control device 8 may be used.

In the above description, a configuration in which a flow rate control device is arranged in each of the piping that constitutes the inlet 2, the piping that constitutes the adsorption outlet 3, and the piping that constitutes the desorption outlet 4 has been described. may be The foreign matter removing apparatus 100 has an on-off valve arranged in each of these pipes, and for adjusting the flow rate of the cleaning fluid at the time of desorption, one or both of the pipe forming the inlet 2 and the pipe forming the discharge port 4 for desorption. A configuration in which a flow rate control device is arranged may be employed.

Further, the foreign matter removing apparatus 100 is not limited to the structure shown in FIGS. 1 to 3, and can be modified, for example, as follows without departing from the gist of the present disclosure.

FIG. 4 is a diagram showing Modification 1 of foreign matter removing apparatus 100 according to Embodiment 1. As shown in FIG.
In the above description, the configuration in which the adsorption outlet 3 and the desorption outlet 4 are separately provided with respect to the container 1 is shown. An adsorption outlet 3 and a desorption outlet 4 are provided. Specifically, a branch pipe is connected to the common outlet 9 to form an adsorption outlet 3 and a desorption outlet 4 on the other side. In this manner, the adsorption outflow port 3 and the desorption outflow port 4 may be provided separately with respect to the container 1, or may be configured to be branched from the common outflow port 9. FIG. In any case, the container 1 has an adsorption outlet 3 and a desorption outlet 4 .

Further, the positions of the inlet 2, the adsorption outlet 3 and the desorption outlet 4 are not limited to the positions illustrated in FIGS. These openings are arranged so that the foreign matter particles 11 do not accumulate in the desorption outlet 4 during desorption and are not prevented from being discharged, and the cleaning fluid flows from the bottom to the top in the storage container 1. It is sufficient if it is provided. The position of the inlet 2 does not matter as long as the fluid can pass through the adsorbent assembly 12 . Specifically, for example, the inlet 2 may be formed on the lower surface of the container 1 . In short, the inlet 2 should be provided so as to supply the fluid toward the lower surface or side surface of the adsorbent assembly 12 . Further, the inlet 2 may be provided on the upper surface of the container 1 as shown in FIG. 5, as long as the fluid can pass through the adsorbent assembly 12 from below.

FIG. 5 is a diagram showing Modification 2 of foreign matter removing apparatus 100 according to Embodiment 1. As shown in FIG.
In Modification 2, the inlet 2 is provided on the upper surface of the container 1 . One end of a pipe 20 is connected to the inlet 2 , and the other end of the pipe 20 extends downward inside the container 1 and is positioned below the adsorbent assembly 12 . In Modified Example 2, the fluid is blown out from the outlet 21 at the other end of the pipe 20 and then passes through the adsorbent assembly 12 . As described above, the foreign matter removing apparatus 100 is provided with the inlet 2 on the upper surface of the container 1 , and the fluid is discharged from the outlet 21 , which is the end of the pipe 20 extending from the inlet 2 into the container 1 , into the adsorbent assembly 12 . You may make it flow towards.

Also, the adsorption outflow port 3 may be formed on the side surface of the container 1 or may be formed on the bottom surface of the container 1 . The adsorption outflow port 3 is preferably located above the upper surface of the adsorbent assembly 12 for the following reasons, but is not limited to this position. The adsorption outflow port 3 is preferably formed above the upper surface of the adsorbent assembly 12 from the viewpoint of allowing the fluid to be treated that has flowed in from the inflow port 2 to pass through the entire adsorbent assembly 12 . By forming the adsorption outflow port 3 above the upper surface of the adsorbent assembly 12, the foreign matter removing apparatus 100 can improve adsorption efficiency during adsorption.

Further, the discharge port 4 for desorption should be formed above the inlet port 2 or the outlet port 21 of the modified example 2 in order to form the flow of the cleaning fluid from the bottom to the top during desorption. Further, the desorption outlet 4 is preferably located above the upper surface of the adsorbent assembly 12 for the following reasons, but is not limited to this position. Since the foreign particles 11 desorbed from the surface of the adsorbent 10 are smaller in diameter than the adsorbent 10 , they float above the container 1 than the adsorbent 10 . Therefore, from the viewpoint of facilitating discharge of the foreign particles 11 , the desorption discharge port 4 is preferably formed above the upper surface of the adsorbent assembly 12 . By forming the discharge port 4 for desorption above the upper surface of the adsorbent assembly 12, the foreign matter removing apparatus 100 can easily discharge the foreign matter particles 11 during desorption.

A foreign matter removing apparatus 100 of Embodiment 1 is an apparatus for removing foreign particles 11 from a fluid to be treated containing foreign particles 11 . A foreign matter removing apparatus 100 includes a container 1 having an inlet 2, an adsorption outlet 3 and a desorption outlet 4, and a plurality of adsorbents 10 that are housed in the container 1 and that adsorb and desorb foreign particles 11. Prepare. The desorption outlet 4 is formed above the inflow port 2 or a blowout port 21 that is the end of the pipe 20 extending from the inflow port 2 into the container 1 . The plurality of adsorbents 10 remove the foreign particles 11 from the fluid to be treated by adsorbing the foreign particles 11 contained in the fluid flowing from the inlet 2 or the outlet 21 toward the adsorption outlet 3 . Also, the plurality of adsorbents 10 desorb the adsorbed foreign particles 11 by flowing inside the container 1 with the cleaning fluid flowing from the inlet 2 or the outlet 21 toward the desorption outlet 4 . The detached foreign particles 11 are discharged from the desorption discharge port 4 .

With the above configuration, the foreign matter removing apparatus 100 causes the adsorbent 10 to flow in the container 1 by the cleaning fluid flowing upward from the bottom during desorption, and desorbs the foreign matter particles 11 from the adsorbent 10 . As described above, the foreign matter removing device 100 desorbs the foreign matter particles 11 by the upward flow of the cleaning fluid, so that the desorption outlet 4 is not blocked by the adsorbent 10 during desorption. Therefore, the foreign matter removing device 100 can stably maintain the ability to discharge the foreign matter particles 11 from the start to the end of the attachment/detachment operation. Moreover, since the foreign matter removing apparatus 100 has a simple configuration in which the adsorbent 10 is provided in the container 1, it has not only adsorption performance and desorption performance, but also energy saving and high maintainability.

The foreign matter removing device 100 of Embodiment 1 is installed at each of the inlet 2, the adsorption outlet 3, and the desorption outlet 4, and prevents the plurality of adsorbents 10 from flowing out of the container 1. An outflow prevention filter 5 is provided.

With the above configuration, the foreign matter removing apparatus 100 can prevent the plurality of adsorbents 10 from flowing out of the container 1 from the inlet 2 , the adsorption outlet 3 , and the desorption outlet 4 .

In the foreign matter removing apparatus 100 of Embodiment 1, a plurality of adsorbents 10 are deposited in the container 1 to form an adsorbent assembly 12, and one or both of the adsorption outlet 3 and the desorption outlet 4 Both are located above the upper surface of the adsorbent assembly 12 .

In this way, with the configuration in which the adsorption outflow port 3 is positioned above the upper surface of the adsorbent assembly 12, the foreign matter removing apparatus 100 can improve the adsorption efficiency during adsorption. In addition, the structure in which the discharge port 4 for desorption is located above the upper surface of the adsorbent assembly 12 makes it easier for the foreign matter removing device 100 to discharge the foreign matter particles 11 during desorption.

Embodiment 2.
Embodiment 2 relates to a foreign matter removing device provided with a flow prevention filter 30. FIG. Hereinafter, the second embodiment will be described with a focus on the configuration different from the first embodiment, and the configurations not described in the second embodiment are the same as those in the first embodiment.

FIG. 6 is a schematic diagram of the foreign matter removing device 101 according to the second embodiment. The foreign matter removing device 101 includes a flow prevention filter 30 that prevents the flow of the adsorbent 10 during adsorption. The anti-flow filter 30 is composed of a mesh plate-like member that allows fluid to pass through. The mesh size of the anti-flow filter 30 may be any size as long as it does not allow the adsorbent 10 to pass through.

A rod member 31 is attached to the upper surface of the anti-flow filter 30 . The rod member 31 extends upward from the upper surface of the anti-flow filter 30 and protrudes to the outside through a through hole provided in the upper surface of the container 1 . An annular fixing member 32 is fitted around the outer periphery of the portion of the rod member 31 protruding from the container 1 to support the rod member 31 . In this manner, the foreign matter removing apparatus 101 can fix the position of the anti-flow filter 30 in the container 1 by supporting the rod member 31 with the fixing member 32 . The fixing member 32 may be composed of a member capable of supporting the rod member 31, such as an annular member made of rubber.

With the above configuration, the anti-flow filter 30 can be moved upward and downward in the container 1 by operating the rod member 31 . The operation of the rod member 31 may be performed manually, or may be performed mechanically by installing a driving device such as a motor for moving the rod member 31 up and down outside the container 1 . The rod member 31 and the fixing member 32 constitute a support portion 33 that supports the anti-flow filter 30 so as to be movable within the container 1 .

(adsorption)
7A and 7B are explanatory diagrams of operations during adsorption in the foreign matter removing device 101 according to the second embodiment. As shown in FIG. 7, during adsorption, the flow prevention filter 30 moves downward toward the adsorbent 10 and presses the adsorbent 10 against the inner surface of the container 1 to prevent the adsorbent 10 from flowing. As a result, the adsorbent 10 does not flow inside the container 1 during adsorption. During adsorption, the fluid to be treated flows into the container 1 from the inlet 2 and flows out from the adsorption outlet 3 . At this time, if the flow prevention filter 30 were not installed, the adsorbent 10 would flow inside the container 1 depending on the flow rate of the fluid to be treated that flows into the container 1 from the inlet 2. The foreign particles 11 cannot be adsorbed efficiently.

In contrast, in the foreign matter removing apparatus 101 of Embodiment 2, the flow prevention filter 30 presses the adsorbent 10 against the inner surface of the container 1 , so that the fluid to be treated at the flow rate of the adsorbent 10 flows into the container 1 . Even if it flows in, the adsorbent 10 will not flow. Therefore, the foreign matter removing device 101 can increase the flow rate of the fluid to be treated without worrying about the flow of the adsorbent 10 . Therefore, the foreign matter removing device 101 can efficiently remove the foreign matter particles 11 from the fluid to be treated in a short time.

(Detachment)
8A and 8B are diagrams for explaining the operation of the foreign matter removing device 101 according to the second embodiment during attachment and detachment. As shown in FIG. 8, the anti-flow filter 30 is moved in a direction away from the adsorbent 10, that is, upward during desorption. As a result, a space for allowing the adsorbent 10 to flow is formed above the adsorbent assembly 12 in the container 1 . When the cleaning fluid flows from the inlet 2 to the desorption outlet 4 in the storage container 1, the adsorbent 10 flows due to the space formed above the adsorbent 10. . The flow rate of the cleaning fluid at this time is the same as the flow rate during desorption described in the first embodiment. In the container 1, the adsorbents 10 repeatedly collide with each other, the foreign particles 11 are desorbed from the surface of the adsorbent 10, and the adsorbing force of the adsorbent 10 is regenerated. The foreign particles 11 desorbed from the adsorbent surface are discharged from the desorption discharge port 4 along with the flow of the cleaning fluid.

When switching to adsorption after finishing the desorption described above, the anti-flow filter 30 moves downward again toward the adsorbent 10 and presses the adsorbent 10 against the inner surface of the container 1 . Note that the foreign matter removing device 101 may set the flow rate of the fluid to zero after the end of desorption until the start of adsorption, or may set the flow rate to such an extent that the adsorbent 10 does not flow, or the flow rate may be the same as that at the time of desorption. It may be the flow rate. In other words, since the foreign matter removing device 102 uses the anti-flow filter 30 to prevent the adsorbent 10 from moving, the flow rate of the fluid between the end of desorption and the start of adsorption is arbitrary.

Here, FIG. 8 shows an example in which the position of the anti-flow filter 30 at the time of detachment is in contact with the inner surface of the upper surface of the container 1, but it may be positioned as shown in FIG. 9 below.

FIG. 9 is a diagram showing a modification of the position of the anti-flow filter 30 at the time of attachment and detachment in the foreign matter removing device 101 according to the second embodiment.
As shown in FIG. 9, the position of the anti-flow filter 30 at the time of attachment/detachment may be below the ejection port 4 for attachment/detachment. In this case, the mesh size of the anti-flow filter 30 may be any size as long as it does not allow the adsorbent 10 to pass through but allows the foreign particles 11 to pass through.

6 to 9, the configuration in which the anti-flow filter 30 moves up and down has been described, but it may be configured to move back and forth or left and right, though not shown. Even if the flow-preventing filter 30 moves back and forth or left and right, the flow-preventing filter 30 presses the adsorbent 10 against the inner surface of the container 1 to prevent the adsorbent 10 from flowing. However, if the anti-flow filter 30 is configured to move back and forth or left and right, it may not be possible to hold down the adsorbent 10 with a uniform thickness when switching from desorption to adsorption. Therefore, it is desirable to move the anti-flow filter 30 up and down as shown in FIGS.

According to the second embodiment, effects similar to those of the first embodiment can be obtained, and the following effects can be obtained because the anti-flow filter 30 is provided. The foreign matter removing device 101 can increase the flow rate of the fluid to be treated that flows into the container 1 during adsorption compared to the first embodiment, and the foreign matter removing device 101 efficiently removes foreign matter particles from the fluid to be treated in a short time. 11 can be removed.

Embodiment 3.
Embodiment 3 relates to a technique for suppressing bias of the adsorbent 10 inside the container 1 at the start of adsorption. Hereinafter, the description of the third embodiment will focus on the configuration different from that of the second embodiment, and the configurations not described in the third embodiment are the same as those of the second embodiment.

FIG. 10 is a schematic diagram of the foreign matter removing device 102 according to the third embodiment.
The anti-flow filter 30 is supported by a support portion 33 so as to be able to vibrate or rotate. The anti-flow filter 30 can vibrate up and down, right and left, or rotate about an axis extending in a movement direction by operating a rod-shaped portion protruding from the outside of the container 1 . The vibration and rotation of the anti-flow filter 30 may be performed manually, or may be performed mechanically using a driving device such as a motor.

The foreign matter removing apparatus 102 of Embodiment 3 moves the anti-flow filter 30 downward to press the adsorbent 10 against the inner surface of the container 1 before starting adsorption. At this time, the foreign matter removing device 102 moves the anti-flow filter 30 downward while vibrating or rotating it. Since the adsorbent 10 is flowing when the foreign particles 11 are desorbed, the adsorbent 10 may be deposited in a biased state when the adsorbent 10 settles and accumulates in the lower part of the container 1 after the desorption is completed. For this reason, the foreign matter removing device 102 suppresses uneven deposition of the adsorbent 10 by moving the anti-flow filter 30 downward while vibrating or rotating it.

In addition, the foreign matter removing device 102 moves the anti-flow filter 30 while vibrating or rotating it, so that the upper surface of the adsorbent 10 can be made uniform, and the adsorbent assembly 12 having the same shape is formed every time adsorption is started. can. As a result, the foreign matter removing device 102 can suppress a decrease in adsorption efficiency during adsorption, and can stably maintain the adsorption efficiency.

Note that the foreign matter removing device 102 may set the flow rate of the fluid to zero after the end of desorption until the start of adsorption, or may set the flow rate to such an extent that the adsorbent 10 does not flow, or the flow rate may be the same as that during desorption. It may be the flow rate. In other words, since the foreign matter removing device 102 uses the anti-flow filter 30 to prevent the adsorbent 10 from moving, the flow rate of the fluid between the end of desorption and the start of adsorption is arbitrary.

According to the third embodiment, the same effects as those of the second embodiment are obtained, and the anti-flow filter 30 is supported so as to be able to vibrate or rotate. made it move. As a result, after switching from desorption to adsorption, the foreign matter removing device 102 can suppress uneven deposition of the adsorbent 10, and stably maintain adsorption efficiency.

Embodiment 4.
Embodiment 4 relates to a foreign matter removing device that includes a water quality meter that measures the water quality of a fluid and that switches between adsorption and desorption based on the measurement result of the water quality meter. Hereinafter, the fourth embodiment will be described with a focus on the configuration different from that of the first embodiment, and the configurations not described in the fourth embodiment are the same as those in the first embodiment.

FIG. 11 is a schematic diagram of the foreign matter removing device 103 according to the fourth embodiment. FIG. 11 shows the operation during adsorption. The foreign matter removing apparatus 103 of Embodiment 4 further includes a water quality meter for measuring the water quality of the fluid in addition to the configuration of Embodiment 1. FIG. Here, the foreign matter removing device 103 includes a first water quality gauge 40 and a second water quality gauge 41 . The first water quality gauge 40 is arranged downstream of the adsorption outflow port 3 or the adsorption outflow port 3 , and the second water quality gauge 41 is installed downstream of the desorption discharge port 4 or the desorption discharge port 4 . The water quality meter consists of, for example, a turbidity meter capable of measuring the turbidity of the fluid or a color difference meter capable of measuring the color difference. A water quality meter indicates that the higher the measured value, the worse the water quality.

In the foreign matter removing device 103, when the adsorption of the foreign particles 11 by the adsorbent 10 progresses and the adsorption state reaches a saturated state, the foreign particles 11 that have not been adsorbed by the adsorbent 10 pass through the adsorbent assembly 12 to reach the adsorption outflow port. It flows out from 3. As a result, the water quality of the fluid flowing out from the adsorption outflow port 3 becomes worse than that at the start of adsorption. On the other hand, in the foreign matter removing device 103, as the desorption of the foreign matter particles 11 from the adsorbent 10 progresses, the quality of the fluid flowing out from the desorption outlet 4 improves from that at the start of desorption.

The foreign matter removing device 103 measures such changes in water quality during adsorption and desorption using the first water quality meter 40 and the second water quality meter 41, and switches between adsorption and desorption based on the measurement results. . Specifically, the foreign matter removing device 103 switches from adsorption to desorption when the measured value of the first water quality meter 40 is greater than or equal to a preset first set value during adsorption. On the other hand, the foreign matter removing device 103 switches from desorption to adsorption when the measured value of the second water quality meter 41 becomes equal to or less than a preset second set value during desorption. Switching between desorption and adsorption may be performed automatically or manually by providing a switching device for controlling the opening of each flow control device. When it is performed manually, the user may check the measured values of the first water quality meter 40 and the second water quality meter 41 and perform it. The first set value and the second set value can be freely set according to the mode of use of the foreign matter removing device 103 .

In this way, by determining the switching timing between adsorption and desorption using the water quality meter, the foreign matter removing device 103 can switch between adsorption and desorption at appropriate timing. Here, if the switching between adsorption and desorption is not performed at an appropriate timing, the adsorption operation is continued in a state where the adsorption capacity of the adsorbent 10 is lowered, and the removal efficiency of the foreign particles 11 is lowered and the performance is lowered. There is a risk of causing However, the foreign matter removing device 103 can improve the removal efficiency of the foreign matter particles 11 by switching between adsorption and desorption at appropriate timing.

Although the water quality meter is arranged so as to measure the water quality of the fluid passing through the adsorption outflow port 3 and the desorption outlet 4 in the above description, it may be arranged in the container 1 . When the water quality meter is arranged in the container 1, it is arranged so as to measure the water quality of the fluid in the upper part of the container 1, that is, the water quality immediately before flowing into the adsorption outlet 3 and the desorption outlet 4. . In this case, the foreign matter removing device 103 can determine switching timings from desorption to adsorption and from adsorption to desorption with one water quality meter.

Further, in the above, two water quality meters are arranged so that the water quality of both fluids passing through the adsorption outlet 3 and the desorption outlet 4 can be measured, and switching from adsorption to desorption and from desorption to adsorption is performed. Although the configuration in which the timing can be determined has been described, the following may be used. The foreign matter removing device 103 has a water quality meter arranged in one of the adsorption outlet 3, the desorption outlet 4, and the container 1, and determines at least one switching timing from adsorption to desorption and desorption to adsorption. I wish I could.

According to the fourth embodiment, effects similar to those of the first embodiment are obtained, and the following effects are obtained since the water quality meter for measuring the water quality of the fluid is provided. The foreign matter removing device 103 can determine an appropriate switching timing between adsorption and desorption according to the measurement result of the water quality meter, and as a result, the removal efficiency of the foreign matter particles 11 can be improved.

Embodiment 5.
Embodiment 5 relates to a foreign matter removing apparatus which has a configuration different from that of Embodiment 4 and determines switching timing between adsorption and desorption. Hereinafter, the description of the fifth embodiment will focus on the configuration different from that of the first embodiment, and the configurations not described in the fifth embodiment are the same as those of the first embodiment.

A foreign matter removing apparatus 104 according to Embodiment 5 has a configuration in which an observation window 50 is installed in the container 1 so that the inside of the container 1 can be visually observed from the outside of the container 1 . The user switches between adsorption and desorption based on the result of observing the inside of the container 1 through the observation window 50 . The observation window 50 is installed in the height range of the adsorbent assembly 12 so that the state of adsorption of the foreign particles 11 to the adsorbent 10 can be confirmed.

During adsorption, the user switches from adsorption to desorption at the timing when the foreign particles 11 adhere to the surface of the adsorbent 10 and the adsorption state becomes saturated and the color of the adsorbent surface changes. Further, the user switches from desorption to adsorption at the timing when the foreign particles 11 are desorbed from the adsorbent surface and the color of the adsorbent surface returns to the original color of the adsorbent 10 during desorption.

In the above description, the observation window 50 is installed in the height range of the adsorbent assembly 12. However, it may be installed on the upper side of the container 1 so that the water quality in the upper part of the container 1 can be observed. good. In this case, during adsorption, if the quality of the fluid that can be observed through the observation window 50 deteriorates from that at the start of adsorption, the user switches from adsorption to desorption. Also, during desorption, when the quality of the fluid observable through the observation window 50 is improved from that at the start of adsorption, the user switches from desorption to adsorption.

Incidentally, in the foreign matter removing device 104, instead of installing the observation window 50 in the container 1, the container 1 itself may be made of a transparent material. In this case, the foreign matter removing device 104 can also have the same function as the observation window 50 .
