Description

TECHNICAL FIELD The present invention relates to a sparging device and a catalyst filling device comprising the sparging device.

Various catalysts are used in petroleum refining facilities, chemical industry facilities, and the like to promote chemical reactions. The catalyst is shaped, for example, in the form of granules, and packed inside a reaction tower through which the raw material fluid is circulated.
For such catalyst filling, a catalyst filling apparatus disclosed in Patent Document 1 and Patent Document 2 is used.

The catalyst filling device of Patent Document 1 is equipped with a catalyst ejector for dispersing the catalyst inside the reaction tower. It is a structure in which the rotor mechanism is driven by a rotation drive mechanism.
The rotary drive mechanism is controlled by a control means such that the catalyst discharged by the catalyst discharger is evenly packed in the reactor.

The catalyst filling device of Patent Document 2 fills a reaction column with a catalyst so that a concave portion is formed in the central portion in the shape of an angle of repose. be. Due to the centrifugal force due to the rotation of the rotating disk and the drop impact force from a high position, the catalyst is densely packed in the inner circumference of the reaction tower. Of the catalyst deposited in the cylindrical shape, part of the catalyst on the top of the inner peripheral portion becomes the catalyst that naturally falls down the slope of the recess. This catalyst is filled in the central part while maintaining the coarse density.

JP-A-8-281094 Japanese Patent No. 3004446

In the conventional example of Patent Document 1, a plurality of dispersing rotors are stacked in a multistage manner at predetermined intervals, and when the dispersing rotor mechanism is rotationally driven, the catalyst is radially displaced from the outer peripheral edge of each dispersing rotor. released to
Catalysts with different sizes are mixed in the reaction tower. A large catalyst will be blown to the inner periphery of the reaction tower by the centrifugal force accompanying the rotation of the dispersing rotor, but a small catalyst will stay at the center of the reaction tower, and the size of the dispersed catalyst will be will be unevenly distributed depending on the location to be filled.

After the catalyst filling operation, a reaction operation is performed in which a raw material fluid such as oil is evenly distributed over the catalyst packed in the reaction tower from the top of the reaction tower to circulate the raw material fluid.
Here, in the inner peripheral portion of the reaction tower, since the size of the packed catalyst is large, the gaps between the many dispersed catalysts become large. Therefore, in the vicinity of the inner wall of the reaction tower, it becomes easier for the raw material fluid to flow, and the amount of the raw material fluid to be circulated increases.
On the other hand, in the central part of the reaction tower, since the size of the packed catalyst is small, the gaps between the many dispersed catalysts become small, and it becomes difficult for the raw material fluid to flow in the central part of the reaction column. , the amount of raw material fluid to be circulated is small.
Therefore, when the raw material fluid is circulated for the reaction work after the catalyst is filled, the amount of the flow varies depending on the position of the filled catalyst, so there is a problem that the reaction work is inefficient.

In the conventional example of Patent Document 2, the inner peripheral portion of the reaction column is filled with a high-density catalyst, and the central portion is filled with a coarse-density catalyst. Differences are not taken into consideration, and the size of the catalyst dispersed by the rotating disk is unevenly distributed inside the reaction tower.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sprinkling device and a catalyst filling device capable of uniformly sprinkling materials having different particle diameters without size unevenness.

A sprinkling device of the present invention comprises a cup member having a discharge port formed between a bottom portion and an opening edge for accommodating materials to be distributed having different particle diameters and discharging the materials to be distributed, and an inner peripheral portion of the cup member. a regulating portion that regulates the relative movement of the material to be sprayed with the cup member, a stirring blade that stirs the material to be sprayed discharged from the discharge port, and the cup member and the stirring blade. and a rotating mechanism for rotating.

In the sprinkling device of the present invention, when the rotating mechanism operates with the material to be spread stored inside the cup member, the cup member, the regulating portion, and the stirring blade rotate. Then, the rotating cup member idly rotates against the material to be dispersed, which tends to stop due to inertia, and the material to be dispersed moves relative to the cup member, but is fixed to the inner peripheral portion of the cup member. The restricting portion restricts the relative movement and rotates together with the cup member. Then, the material to be dispersed is dispersed to the outside from the outlet formed in the cup member by centrifugal force.
Over the entire length of the outlet formed from the bottom of the cup member toward the edge of the opening, the material to be distributed, which is a mixture of large and small particle sizes, is dispersed.
Due to the large centrifugal force, the material to be dispersed, which has a large particle size, is dispersed far away from a portion of the discharge port near the opening edge of the cup member. From the part near the bottom, in addition to the small particle size material to be dispersed, the material to be dispersed with a large particle size is mixed and dispersed downward, but by the agitating blade that rotates together with the cup member , are agitated, so uneven distribution of the size of the material to be sprayed is reduced. In other words, the materials to be sprayed with different particle diameters are agitated by direct contact with the agitating blades rotating integrally with the cup member, or by the airflow generated by the rotating agitating force.

In the present invention, the restricting portion includes a first shaft portion and a restricting plate portion fixed to the first shaft portion, and the stirring impeller is a second shaft portion coaxially connected to the first shaft portion. The configuration may include a biaxial portion and an agitating plate portion fixed to the second axial portion.
In this configuration, the first shaft portion and the second shaft portion are coaxially connected, the first shaft portion and the regulating plate portion are fixed, and the second shaft portion and the stirring plate portion are fixed to form the regulating portion. A stirring blade was integrally formed. Therefore, by rotationally driving the first shaft portion and the second shaft portion, the cup member, the regulating plate portion and the stirring plate portion can be rotated at the same time, thereby simplifying the structure of the sprinkling device.

The catalyst filling device of the present invention is characterized by comprising a spraying device having the above configuration, wherein the material to be sprayed is a catalyst, and the spraying device fills the interior of the reaction tower with the catalyst.
In the present invention, when the first shaft portion and the second shaft portion are rotated by the rotation mechanism while the catalyst is stored inside the cup member, the catalyst is discharged from the discharge port of the cup member regardless of the particle size. be. Since the catalyst discharged from the discharge port is stirred by the stirring blades, the uneven distribution of the size of the catalyst packed in the reaction tower is reduced.
Therefore, when the reaction work is performed by flowing the raw material fluid into the reaction tower after filling the catalyst, the raw material fluid flows evenly regardless of the location of the reaction tower, so that the efficiency of the reaction work can be improved.

In the present invention, a control device is provided to send a signal for changing the rotation of the cup member and the stirring blade to the rotation mechanism, and the control device fills the inner circumference of the reaction tower with the catalyst at a high density. A high-speed rotation mode in which the cup member and the stirring blades are rotated at a high speed in order to perform high-speed rotation, and a low-speed rotation mode in which the cup member and the stirring blades are rotated at a low speed in order to fill the catalyst in the central part of the reaction tower with a coarse density. A signal for switching between and may be sent to the rotating mechanism.
In this configuration, when a high-speed rotation mode signal is sent from the controller to the rotating mechanism, the rotating mechanism rotates the cup member and the stirring blade at high speed. Among the catalysts accommodated in the cup member, mainly large catalysts are scattered far from the upper end of the outlet toward the inner wall of the reaction tower due to the large centrifugal force, and catalysts of different sizes are dispersed in the outlet. It is sprayed by falling from the bottom end to the center. By continuing this state for a long time, the amount of catalyst packed in the inner circumference of the reaction tower increases, and the high-density catalyst packed in the inner circumference of the reaction tower becomes cylindrical.
Thereafter, when the controller sends a signal to the rotating mechanism to switch from the high-speed rotation mode to the low-speed rotation mode, the cup member will rotate at a low speed. The centrifugal force of the catalyst stored in the cup member is reduced, and most of the catalyst is dispersed in the central part without reaching the inner peripheral part of the reaction tower from the outlet. By continuing this state for a certain period of time, the interior of the high-density catalyst formed in the cylindrical shape of the reaction column is filled with the low-density catalyst.
By repeating the above modes, a high-density catalyst is formed over a predetermined height in the inner peripheral portion of the reaction column, and a coarse-density catalyst is formed over a predetermined height in the central portion.
Here, in both the high-speed rotation mode and the low-speed rotation mode of the cup member, particularly in the low-speed rotation mode, the large and small catalysts discharged from the lower end of the discharge port are directly stirred by the stirring blade rotating together with the cup member. Since the catalyst is agitated by the airflow generated by the rotation of the blades, uneven distribution of the size of the catalyst packed in the reaction tower is reduced.

In the present invention, a control device for sending a signal for changing the rotation of the cup member and the stirring blade to the rotation mechanism is provided, and the control device has a forward rotation mode for rotating the cup member and the stirring blade forward. and a reverse rotation mode in which the cup member and the stirring blade are rotated in reverse.
In this configuration, when a forward rotation mode signal is sent from the control device to the rotation mechanism, the cup member rotates forward while discharging the catalyst into the reaction tower through the discharge port. At this time, if the cup member rotates at a high speed for a long period of time, the inner peripheral portion of the reaction tower is filled with a high-density catalyst in a cylindrical shape. After that, when the control device sends a signal to switch from the forward rotation mode to the reverse rotation mode to the rotation mechanism, the rotation speed of the cup member is reduced by the rotation mechanism until the cup member rotates from the forward rotation to the reverse rotation, and eventually stops. After that, it starts to rotate in the reverse direction at a low speed, and after a predetermined time has passed, it rotates at a high speed. The cup member rotates at low speed or stops during the time from high-speed rotation to stop in forward rotation and from stop to high-speed rotation in reverse rotation, so that the central portion of the reaction column is filled with coarse-density catalyst. be.
By alternately switching between the forward rotation mode and the reverse rotation mode of the cup member and the stirring blade, the high-density catalyst filled in the inner peripheral part of the reaction tower and the coarse-density catalyst filled in the central part is filled inside the reaction column until it reaches a predetermined height.
Here, when a long member such as a thermometer is arranged to extend vertically inside the reaction tower, if the cup member only rotates in one direction, the catalyst hits the member from one direction, It becomes difficult for the catalyst to accumulate in the shaded area. Therefore, in this configuration, by repeating normal rotation and reverse rotation of the cup member, the shadow portion of the member is eliminated, and the catalyst can be evenly filled in the reaction tower.

In the present invention, the restricting portion linearly closes a part of the discharge port from the bottom of the peripheral surface of the cup member along the radial direction, and the exhaust port closes the portion blocked by the restricting portion. The sandwiched cup member has a first opening and a second opening on both sides in the circumferential direction, the upper end of the first opening is higher than the upper end of the second opening, and the control device is When the inner peripheral portion of the reaction tower is filled with the catalyst at high density, the cup member and the stirring blade are rotated forward so that the catalyst is discharged from the first opening, and the center of the reaction tower is When filling the catalyst with a coarse density in the part, the cup member and the stirring blade may be reversely rotated so that the catalyst is discharged from the second opening.
In this configuration, when a forward rotation mode signal is sent from the control device to the rotation mechanism, the catalyst is discharged from the first opening of the forwardly rotating cup member and filled in the reaction tower, and the reverse rotation mode signal is sent. When sent, the catalyst is discharged from the second opening of the counter-rotating cup member and filled in the reactor. Here, since the position of the upper end of the first opening is higher than that of the second opening, when the cup member is rotated in the normal direction, the catalyst is dispersed far from the high position of the cup member. It is effective when the part is filled with a high-density catalyst. On the other hand, when the cup member is rotated in the reverse direction, the catalyst is not sprayed from a high position of the cup member, so even if the cup member rotates at high speed, the catalyst does not easily reach the inner peripheral portion, which is suitable for filling the central portion with the catalyst. is.

In the present invention, a hopper for storing a mixture of the catalyst and catalyst powder smaller than the catalyst, and a separation device for separating the catalyst supplied from the hopper from the catalyst powder and sending it to the spraying device, wherein the separation The device comprises a catalyst tube through which the catalyst and the catalyst powder are mixed and circulated, an inner tube arranged inside the catalyst tube, and an outer tube arranged outside the catalyst tube, wherein the catalyst The tube has a peripheral surface portion formed with a plurality of communication holes through which the catalyst powder can pass but through which the catalyst cannot pass, and the inner tube is a catalyst powder discharger for discharging the catalyst powder from the communication holes. a wall portion formed with a plurality of fluid supply holes for supplying a fluid to the space between the catalyst tube and the catalyst tube; At least one of the peripheral surface portion of the catalyst tube and the wall portion of the inner tube has a vortex generating portion that generates a vortex in the flow of the mixture of the catalyst powder and the catalyst. The fluid supply hole may be arranged to face at least a position where a vortex is generated in the vortex generating section.
In this configuration, the catalyst contained in the hopper and the catalyst powder are separated by the separating device, the catalyst powder is discharged outside the separating device, and the catalyst is sent to the spraying device.
In the separator, a mixture of the catalyst and the catalyst powder flows axially inside the catalyst tube and hits the vortex generating portion to generate a vortex. When a vortex is generated in the flow of inclusions, catalyst powder, which is smaller than the catalyst, stays in a turbulent state.
A fluid for discharging the catalyst powder flowing inside the inner tube is sent to the inside of the catalyst tube from the fluid supply hole. Since the fluid supply hole is arranged to face the position where the vortex is generated in the vortex generating portion, the catalyst powder staying in the vortex state is pushed out toward the communication hole. Then, the catalyst powder is efficiently discharged into the storage space between the outer tube and the catalyst tube through the communication holes. On the other hand, even if the catalyst itself is pushed out by the fluid for discharging the catalyst powder, it cannot pass through the communication hole, so it continues to flow inside the catalyst tube along the axial direction. Therefore, at least one of the peripheral surface portion of the catalyst tube and the wall portion of the inner tube is provided with a vortex generating portion for generating a vortex in the flow of the mixture of the catalyst and the catalyst powder. Since the position where the vortex is generated is opposed to the position where the vortex is generated by the vortex generation part, the catalyst powder staying in the vicinity of the vortex generation part becomes turbulent by the vortex generation part, and the fluid sent from the fluid supply hole flows into the communication hole. As a result, the catalyst powder is efficiently discharged into the storage space. On the other hand, since the catalyst itself continues to flow inside the catalyst tube, the catalyst and the catalyst powder are reliably separated.

A mixed material 2B is stored in the hopper 11. - 特許庁The mixture 2B is sent from the hopper 11 to the separator 20. FIG.
In the separation device 20, the mixture 2B sent from the hopper 11 flows downward through the space 21A between the catalyst tube 21 and the inner tube 22. As shown in FIG. Then, the mixed matter 2B flowing through the portion near the inner tube 22 of the mixed matter 2B hits the second fins 81 and its flow is obstructed, and the mixed matter 2B flowing through the portion near the outer tube 23 is blocked by the first fins 80. , it flows along the upper surface (surface) of the first fin 80 from the base end side to the tip end. A vortex P is generated immediately after the inclusion 2B separates from the tip of the first fin 80 . Due to the eddy current P, the catalyst powder 2A smaller than the catalyst 2 among the inclusions 2B flows turbulently. Accompanied by the vortex flow P, the catalyst powder 2A enters the area Q formed between the lower portions of the first fins 80 and stays therein.

Here, when the dust-removed air is sent to the inside of the inner tube 22, the dust-removed air passes through the fluid supply hole 221 located above the proximal end of the second fin 61, and the second fin 81 blocks the flow of the dust-removed air. The material 2B is reversed and sent to the catalyst tube 21 side, and further, the catalyst powder 2A staying under the first fin 80 is pushed out toward the communication hole 211 by the swirl P, and the catalyst powder 2A is pushed out together with the dust removal air. is stored in the storage space 23A through the communication hole 211. The catalyst powder 2A stored in the storage space 23A is sucked by the dust-removed air discharge pipe 25 and the exhaust mechanism 26. As shown in FIG.
When the storage space 23A is sucked by the dust-removed air discharge pipe 25 and the exhaust mechanism 26, a negative pressure is generated in the space 21A between the catalyst pipe 21 and the inner pipe 22, and the catalyst powder 2A in the space 21A is forcibly removed. It is sent through the communication hole 211 to the storage space 23A. Since the catalyst 2 larger than the catalyst powder 2A does not pass through the communication hole 211, it is sent downstream.

[Spraying process]
The large and small catalysts 2 sent from the separation device 20 are sent to the spraying device 50 and sprayed inside the reaction tower 1 .
First, when the valve 40 is opened in response to a signal from the control device 5 , the catalysts 2 mixed in size are sent inside the cup member 52 through the casing 51 of the sprinkling device 50 . After the catalyst 2 is accommodated in the cup member 52, it is discharged into the reaction tower 1 through the discharge port 52B.
Then, the controller 5 is operated through an operation panel (not shown). For example, a signal is sent to the rotation mechanism 54 through the control device 5 to repeat the forward rotation mode and the reverse rotation mode at predetermined time intervals, and to switch between the high-speed rotation mode and the low-speed rotation mode in each mode.
When the rotation mechanism 54 receives a signal from the control device 5, the air supplied from the air supply source 543 causes the cup member 52 and the stirring blade 53 to rotate forward and at high speed through the air motor 541 and the shaft body 530. It is discharged through discharge tube 544 .

First, when the cup member 52 and the stirring blade 53 are rotated forward (clockwise in FIG. 5) and at high speed by the rotation mechanism 54, the catalyst 2 accommodated in the cup member 52 is rotated at high speed together with the cup member 52 by the regulation portion 52M. As a result, catalysts 2 of different sizes are dispersed inside reaction tower 1 from first opening 52B1. Since the cup member 52 rotates forward, the catalyst 2 is discharged from the upper end to the lower end of the first opening 52B1. It is sprayed from the upper end of the opening 52B1, reaches the inner wall of the reaction tower 1, and is sprayed on the inner peripheral portion A. The remaining catalyst 2, which is mixed in size, falls downward from the lower end of the first opening 52B1 and is directly stirred by the stirring blades 53 rotating together with the cup member 52, or by the airflow generated by the stirring blades 53. Indirectly agitated. A small amount of the stirred catalyst 2 is dispersed in the central portion B.

After that, when a signal for switching from the high-speed rotation mode to the low-speed rotation mode is sent to the rotation mechanism 54 from the control device 5, the rotation mechanism 54 rotates the cup member 52 and the stirring blade 53 at a low speed for a predetermined time, and then stops. do. Since the centrifugal force of the catalyst 2 dispersed from the first opening 52B1 is small, most of the catalyst 2 gathers in the central portion B without reaching the side wall of the reaction tower 1 . Through this process from high-speed rotation to low-speed rotation and then to stop, the mixed large and small catalysts 2 are scattered downward from the lower end of the first opening 52B1 and are stirred by the stirring blades 53. become. As a result, the upper surface of the packed catalyst 2 forms a line L11 that is highest on the inner wall side of the reaction tower 1 and slopes downward along the axis (see FIG. 1).

Furthermore, when a signal for switching from the forward rotation mode to the reverse rotation mode and the low-speed rotation mode is sent to the rotation mechanism 54 from the control device 5, the rotation mechanism 54 causes the cup member 52 and the stirring blade 53 to reverse from the stopped state. The direction is switched to low-speed rotation for a predetermined time, and the catalyst 2 contained in the cup member 52 is dispersed toward the central portion B from the second opening 52B2 while being stirred by the stirring blades 53. After that, the rotation is switched from the low speed to the high speed, but since the upper end position of the second opening 52B2 is lower than the upper end position of the first opening 52B1, even if the rotation becomes high speed, the upper end of the second opening 52B2 does not move. The amount of catalyst 2 reaching the side wall of the reaction tower 1 is small. As a result, the upper surface of the packed catalyst 2 forms a line L1 that is highest on the inner wall side of the reaction tower 1 compared to the line L11 and that slopes downward along the axis (see FIG. 1).
Here, in the case where long members (not shown) such as thermometers are arranged vertically inside the reaction tower 1, if the cup member 52 rotates forward, the long members will only move in one direction. Since the catalyst 2 hits the part from the long member, the catalyst 2 is not sufficiently filled in the shadow part of the elongated member. However, the reverse rotation of the cup member 52 causes the catalyst 2 to be filled in the shadow of the long member.

Then, when a signal for switching from the reverse rotation mode to the forward rotation mode and the high-speed rotation mode is sent to the rotation mechanism 54 from the control device 5, the rotation mechanism 54 rotates the cup member 52 and the stirring blade 53 from high-speed rotation to once. After stopping, it switches to high-speed rotation in the positive direction. Then, the catalyst 2 housed in the cup member 52 is dispersed toward the central portion B from the second opening 52B2 at the time of stopping and at the time of low speed rotation immediately before that, and further at the time of stopping and at the time of low speed rotation immediately after, It is sprayed toward the central portion B from the first opening portion 52B1. When the cup member 52 rotates in the forward direction at high speed, the large catalyst 2 is mainly discharged from the upper end of the first opening 52B1 toward the side wall of the reaction tower 1 to form the inner peripheral portion A, as described above. . Then, the cup member 52 and the stirring blades 53 are again switched from high-speed rotation to low-speed rotation by the rotating mechanism 54 and then stopped, and most of the large and small catalysts 2 are dispersed in the central portion B. Through this process from high-speed rotation to low-speed rotation and then to stop, the mixed large and small catalysts 2 are scattered downward from the lower end of the first opening 52B1 and are stirred by the stirring blades 53. As a result, the inside of the reactor 1 is filled with the catalyst 2 along the line L2.
By repeating the above modes, the high-density catalyst 2 is formed over a predetermined height in the inner peripheral portion A of the reaction tower 1, and the coarse-density catalyst 2 is formed over a predetermined height in the central portion B. It is formed. Furthermore, the catalyst 2 is filled so that the upper surface is along the line L2, the line L3, the line L4, . . . , the line LN. The catalyst 2 is filled on the line LN so as to form a line LT with a completely flat top surface. In this embodiment, as the lines L1, L2, L3, L4, . .

Further, in this embodiment, only a signal for switching between the forward rotation mode and the reverse rotation mode may be sent to the rotation mechanism 54 through the control device 5 at predetermined time intervals. When the cup member 52 rotates in the forward rotation mode, a large catalyst 2 is dispersed from the first opening 52B1 to form a cylindrical inner peripheral portion A. When the cup member 52 rotates in the reverse rotation mode, The central portion B is formed by scattering large and small catalysts 2 from the second opening 52B2. When the central portion B is formed, the large and small catalysts 2 are stirred by the stirring blades 53 to be evenly distributed.
In addition, in order to fill the inner peripheral portion A with the catalyst 2 at high density and the central portion B with the catalyst 2 at low density, the catalyst 2 is deposited in a cylindrical shape along the inner wall of the reaction tower 1, and the cylinder A part of the catalyst 2 deposited in a shape may be allowed to fall naturally, and the central portion B may be formed by the fallen catalyst 2 . In this case, in order to form the central portion B, the amount of the catalyst 2 sprayed from the cup member 52 is reduced.

[Reaction step]
After the spraying step is completed, the catalyst filling device 3 is removed from the reaction tower 1, and the raw material fluid is poured into the catalyst 2 packed inside the reaction tower 1 from the upper part of the reaction tower 1. At this time, the high-density catalyst 2 is filled in the inner peripheral portion A, and the coarse-density catalyst 2 is filled in the central portion B, and the inner peripheral portion A and the central portion B, particularly the central portion B, Since the large and small catalysts 2 are evenly packed, the raw material fluid flows regardless of the position where the catalyst is packed, for example, the central portion B or the inner peripheral portion A of the reactor 1 .

[Action and effect of the embodiment]
In this embodiment as described above, the following effects are obtained.
(1) A cup member 52 containing a catalyst 2 as a material to be sprayed having different particle sizes and having an outlet 52B for discharging the catalyst 2 formed between the bottom and the opening edge, and the catalyst contained in the cup member 52. 2, a regulating portion 52M that regulates the relative movement of the cup member 52, a stirring blade 53 that stirs the catalyst 2 discharged from the discharge port 52B, and a rotating mechanism 54 that rotates the cup member 52 and the stirring blade 53. , and the spraying device 50 is configured. Therefore, from the portion near the upper end of the discharge port 52B, mainly the catalyst 2 having a large particle size is scattered far away due to the large centrifugal force, and from the portion near the bottom, a mixture of large and small catalysts is dispersed. 2 is scattered downward, but since the catalyst 2 is stirred by the stirring blade 53 that rotates together with the cup member 52, uneven distribution of the size of the catalyst 2 is reduced.

(2) The regulation portion 52M is formed by fixing the regulation plate portion 534 to the first shaft portion 533, and the stirring blade 532 is formed by fixing the stirring plate portion 536 to the second shaft portion 535. Therefore, by rotating the first shaft portion 533 and the second shaft portion 535, the cup member 52, the regulating plate portion 534, and the stirring plate portion 536 can be rotated at the same time, so that the structure of the sprinkling device 50 can be simplified. can be made into something
(3) Since the control device 5 is provided to send a signal to the rotation mechanism 54 for changing the rotation of the cup member 52 and the stirring blade 53, it is possible to easily set the sprinkling location of the catalyst 2 discharged from the discharge port 52B. can.

(4) Since the discharge port 52B is formed in a slit shape along the radial direction from the bottom of the cup member 52, the structure of the discharge port 52B can be simplified.
(5) The discharge port 52B is divided into a first opening portion 52B1 and a second opening portion 52B2 on both sides of the portion linearly blocked by the restricting portion 52M, and the upper end of the first opening portion 52B1 is the second opening portion. When the inner peripheral portion A of the reaction tower 1 is filled with the catalyst 2 at a high density, the catalyst 2 is discharged from the first opening 52B1. When the cup member 52 and the stirring blade 53 are rotated forward and the catalyst 2 is filled in the central portion B of the reaction tower 1 at a coarse density, the cup member 52 and the stirring blade 53 are rotated so that the catalyst 2 is discharged from the second opening 52B2. The blades 53 are configured to rotate in reverse. Therefore, when the cup member 52 rotates in the normal direction, the catalyst 2 is dispersed far from the high position of the cup member 52, which is effective when the inner peripheral portion A is filled with the catalyst 2 at high density. . On the other hand, when the cup member 52 is rotated in the reverse direction, the catalyst 2 is not sprayed from a high position of the cup member 52, so even if the cup member 52 is rotated at high speed, the catalyst 2 hardly reaches the inner wall of the reaction tower 1 and reaches the central portion B. It is suitable for filling the catalyst 2.

(6) Since the catalyst packing device 3 is configured with the spraying device 50 having the above configuration, the catalyst 2 packed in the reaction column 1 has a size of less maldistribution. Therefore, when the raw material fluid is flowed into the reaction tower 1 for reaction work after the catalyst is filled, the raw material fluid flows in the same way regardless of the position of the reaction tower 1, so the efficiency of the reaction work is improved.

(7) Since a plurality of pairs of stirring plate portions 536 are provided along the axial direction of the second shaft portion 535, the catalyst 2 can be sufficiently stirred.
(8) The control device 5 is configured to send a signal to the rotating mechanism 54 for switching between a high-speed rotation mode in which the cup member 52 and the stirring blades 53 are rotated at high speed and a low-speed rotation mode in which the cup member 52 and the stirring blades 53 are rotated at a low speed. Therefore, the high-density catalyst 2 is formed over a predetermined height in the inner peripheral portion A of the reaction column 1, and the coarse-density catalyst 2 is formed over a predetermined height in the central portion B thereof.

(9) The control device 5 is configured to send a signal to the rotating mechanism 54 for switching between a forward rotation mode in which the cup member 52 and the stirring blades 53 are rotated forward and a reverse rotation mode in which the cup member 52 and the stirring blades 53 are reversely rotated. Therefore, when long members such as thermometers are arranged vertically inside the reaction tower 1, by repeating forward and reverse rotation of the cup member 52, the shadow of the long members disappears. , the catalyst 2 can be evenly packed in the reactor 1 .

(10) A vortex generating portion 8 for generating a vortex P in the flow of a mixture 2B of the catalyst 2 and the catalyst powder 2A smaller than the catalyst 2 is provided on the peripheral surface 21B of the catalyst tube 21, and the fluid supply hole 221 of the inner tube 22 is arranged opposite to the position where the vortex P is generated by the vortex generator 8 , the first powder staying in a turbulent state by the vortex generator 8 is removed from the dust-removing air sent from the fluid supply hole 221 to the communication hole 211 . As a result, the catalyst powder 2A is efficiently discharged into the storage space 23A. On the other hand, since the catalyst 2 continues to flow through the space between the inner tube 22 and the catalyst tube, it is reliably separated from the catalyst powder 2A. Moreover, since the vortex generating section 8 is simply provided on the catalyst tube 21, the structure is simple. Moreover, since the catalyst powder 2A and the catalyst 2 are reliably separated by the separation device 20, the purity of the catalyst 2 dispersed inside the reaction tower 1 by the dispersion device 50 is high.

(11) The vortex generating section 8 has a first fin 80 whose tip is directed downstream in the flow direction of the mixed matter 2B, and between the tip of the first fin 80 and the wall portion 22C of the inner pipe 22 Since there is a gap S through which the mixed substance 2B flows, when the mixed substance 2B hits the first fin 80, the catalyst powder 2A turns downward from the tip of the first fin 80 to generate a vortex P. The catalyst powder 2A, which has become turbulent due to the vortex P, is reliably sent to the storage space 23A by the dust-removing air, and is reliably separated from the catalyst 2. - 特許庁Therefore, the vortex P can be reliably generated and the configuration of the vortex generator 8 can be simplified.
(12) Since the first fin 80 is formed in an annular shape centering on the axial center of the catalyst tube 21, there is no part where the first fin 80 is missing along the circumferential direction, and the inclusion of the first fin 80 A vortex of 2B can be reliably generated.
(13) Since the second fins 81 are provided on the outer periphery of the inner pipe 22 to obstruct the flow of the mixed substance 2B along the outer peripheral surface, the mixed substance 2B is agitated and the vortex P is reliably generated. can be done.

(14) Since the dust-removing air discharge pipe 25 for sucking the catalyst powder 2A stored in the storage space 23A and the exhaust mechanism 26 are connected to the outer pipe 23, a negative pressure is generated in the storage space 23A. The catalyst powder 2A inside can be forcibly delivered to the storage space 23A, and from this point also, the catalyst powder 2A and the catalyst 2 can be separated more reliably.

[Modification]
The present invention is not limited to the above-described embodiments, and includes modifications within the scope of achieving the object of the present invention.
For example, in the above-described embodiment, the cup member 52 is configured to include the cup body 521 and the lid member 522 having hemispherical outer and inner peripheries. 520 may be configured to include a bottomed cylindrical cup main body 523 having a disk portion 523A and a tubular portion 523B, and a lid member 522 . In this case, the discharge port 52B may be formed only in the disc portion 523A, or may be formed from the disc portion 523A to the cylindrical portion 523B. The cup member 52 shown in FIG. 7 may use the stirring blade 53 shown in FIG. The restricting plate portion 534 of the restricting portion 52M may have a sector shape as shown in FIG.

Further, in the above-described embodiment, the regulating plate portion 534 and the stirring plate portion 536 each have a rectangular planar shape, but in the present invention, they may have a planar fan shape as shown in FIG. In this case, the linear portion forming the sector may be directed toward the lower portion of the reaction tower 1 and the arc portion may be directed toward the upper portion of the reaction tower 1 .

Furthermore, in the above-described embodiment, the restricting portion 52M and the stirring blade 532 are connected to each other, but in the present invention, they may be separated and driven to rotate by a drive mechanism. Alternatively, a rotating body (not shown) that rolls on the outer circumference of the cup member 52 may be provided, and this rotating body may be used as a rotating mechanism.
In addition, although the discharge port 52B is formed in a slit shape along the radial direction from the bottom of the cup member 52, in the present invention, the discharge port 52B is formed between the center of the bottom of the cup member 52 and the opening edge. For example, the discharge port 52B may be composed of a plurality of holes, and these holes may be arranged side by side along the radial direction from the center of the bottom portion. Even if the discharge port 52B is formed in a slit shape, it does not need to be formed in a straight line as in the above-described embodiment, and is formed in a spiral shape from the bottom of the cup member 52 toward the opening edge. Anything is fine.

In the above embodiment, the discharge port 52B is divided into the first opening portion 52B1 and the second opening portion 52B2 having different upper end positions, but in the present invention, the discharge port 52B may be divided into openings having the same upper end position. , the first opening 52B1 and the second opening 52B2 may be shaped such that the bottom side of the cup member 52 is larger than the opening end.
Further, in the present invention, the control device 5 may be configured to omit switching between the forward rotation mode and the reverse rotation mode, and send only a switching signal between the high-speed rotation mode and the low-speed rotation mode to the rotation mechanism 54 .
Furthermore, in the present invention, the density of the catalyst 2 packed in the reaction column 1 may be made uniform regardless of the inner peripheral portion A and the central portion B.

In the above-described embodiment, a plurality of agitating plate portions 536 are fixed to the outer circumference of the second shaft portion 535 and formed, and these agitating plate portions 536 are formed along the periphery of three sides excluding the base end side in contact with the second shaft portion 535. are exposed to the inside of the reaction tower 1 , but in the present invention, these agitating plate portions 536 may be connected by a plate portion perpendicular to the axis of the second shaft portion 535 . By connecting with the plate portion, the strength of the stirring blade 532 is increased. However, as in the above-described embodiment, if the plurality of stirring plate portions 536 are configured such that the peripheral edges of three sides excluding the base end side in contact with the second shaft portion 535 are exposed inside the reaction tower 1, the plate portions Since the catalyst 2 drops upward and is less likely to be blown to the vicinity of the wall of the reaction tower 1 by the centrifugal force of the plate portion, the deviation in particle size of the dispersed catalyst 2 can be reduced.

In the present invention, the configuration may be such that the separation device 20 is omitted.
Even if the separation device 20 is provided, it is not limited to the configuration of the above embodiment. For example, the second fin 81 may be omitted. It is not necessary to configure the 81 from a plurality of stages, and it may be configured from a single stage.
Furthermore, the material to be sprayed of the present invention is not limited to the catalyst 2 to be sprayed inside the reaction tower 1. For example, aluminum powder, zinc powder, alloy powder, etc. Carbon powder, activated carbon, resin powder, resin beads and other granules used in the chemical field; alumina, clay and other granules used in the ceramics field; salt, refined sugar, granulated sugar used in the food field Granules and granules used in other fields may also be used.
