Description

The present invention relates to a spraying device and a catalyst filling device including a spraying device.

In petroleum refining facilities, chemical industry facilities, etc., various catalysts are used to promote chemical reactions. The catalyst is formed into, for example, granules, and is filled inside a reaction tower through which a raw material fluid flows.
The catalyst filling device shown in Patent Document 1 and Patent Document 2 is used for filling such a catalyst.

The catalyst filling device of Patent Document 1 includes a catalyst discharger for spraying the catalyst inside the reaction tower, and the catalyst discharger has a dispersion having a multi-stage disk-shaped dispersion rotor having a plurality of partition plates. The structure is such that the rotor mechanism is driven by a rotary drive mechanism.
The rotation drive mechanism is controlled by the control means so that the catalyst released by the catalyst discharger is flatly filled in the reaction column.

The catalyst filling device of Patent Document 2 fills the reaction tower with a catalyst so that a recess recessed in an angle of repose is formed in the central portion, and has a structure provided with a rotating disk that discharges the catalyst radially. is there. The catalyst is densely filled in the inner peripheral portion of the reaction column by the centrifugal force due to the rotation of the rotating disk and the drop impact force from a high position. Some of the catalysts deposited in a tubular shape on the top of the inner peripheral portion become catalysts that naturally fall on the slope of the recess. This catalyst is filled in the central part while maintaining the coarse density.

Japanese Unexamined Patent Publication No. 8-281994 Japanese Patent No. 3001464

In the conventional example of Patent Document 1, a plurality of dispersion rotors are stacked in a multi-stage shape at predetermined intervals, and the catalyst is radially driven from the outer peripheral edge of each dispersion rotor by rotationally driving the dispersion rotor mechanism. Is released to.
The catalysts filled in the reaction column are a mixture of catalysts of different sizes. The large catalyst will be blown to the inner circumference of the reaction tower by the centrifugal force accompanying the rotation of the dispersion rotor, but the small catalyst will stop at the center of the reaction tower, and the size of the catalyst to be sprayed. Will be unevenly distributed according to the filling location.

After the catalyst filling operation, a reaction operation is performed in which a raw material fluid such as oil is evenly sprayed from the top of the reaction tower onto the catalyst filled in the reaction tower to distribute the raw material fluid.
Here, in the inner peripheral portion of the reaction tower, the size of the filled catalyst is large, so that the gaps between a large number of sprayed catalysts are large. Therefore, the raw material fluid is easily circulated in the vicinity of the inner wall of the reaction tower, and the amount of the circulated raw material fluid is increased.
On the other hand, in the central part of the reaction tower, the size of the filled catalyst is small, so that the gaps between many catalysts to be sprayed are small, and it becomes difficult for the raw material fluid to flow in the central part of the reaction or the like. , The amount of raw material fluid in circulation is small.
Therefore, if the raw material fluid is circulated after the catalyst is filled for the reaction work, the flow amount differs depending on the position of the filled catalyst, so that there is a problem that the efficiency of the reaction work is poor.

In the conventional example of Patent Document 2, the inner peripheral portion of the reaction tower is filled with a high-density catalyst, and the central portion is filled with a coarse-density catalyst. However, the size of the catalyst filled in the reaction tower is large. The difference is not taken into consideration, and the size of the catalyst sprayed by the rotating disk is unevenly distributed inside the reaction column, which has the same problem as the conventional example of Patent Document 1.

An object of the present invention is to provide a spraying device and a catalyst filling device capable of evenly spraying materials to be sprayed having different particle sizes without uneven distribution of sizes.

In the spraying device of the present invention, a cup member having a discharge port for accommodating spray materials having different particle sizes and discharging the spray material is formed between the bottom and the opening edge, and an inner peripheral portion of the cup member. A regulating unit that is fixed to and 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. It is characterized by having a rotating mechanism for rotating.

In the spraying device of the present invention, when the rotation mechanism operates with the material to be sprayed housed inside the cup member, the cup member, the regulating portion and the stirring blade rotate. Then, the cup member that rotates with respect to the material to be sprayed that is about to stop due to inertia spins idle, and the material to be sprayed moves relative to the cup member, but is fixed to the inner peripheral portion of the cup member. Relative movement is regulated by the regulating part, and it rotates together with the cup member. Then, the material to be sprayed is sprayed to the outside from the discharge port formed in the cup member by centrifugal force.
A mixture of large particle size and small particle size is sprayed over the entire length of the discharge port formed from the bottom of the cup member toward the edge of the opening.
A large centrifugal force causes the spray material having a large particle size to be sprayed far away from the portion of the discharge port near the opening edge of the cup member. From the part near the bottom, in addition to the spray material with a small particle size, the spray material with a large particle size is mixed and sprayed downward, but due to the stirring blade that rotates with the cup member. Since it is agitated, the uneven distribution of the size due to the spraying of the material to be sprayed is reduced. That is, the materials to be sprayed having different particle sizes directly hit the rotating stirring blade integrally with the cup member, or are agitated by the air flow generated by the rotating stirring force.

In the present invention, the regulating portion includes a first shaft portion and a regulating plate portion fixed to the first shaft portion, and the stirring blade is coaxially connected to the first shaft portion. A configuration may be provided in which a biaxial portion and a stirring plate portion fixed to the second shaft portion are provided.
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. The 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, so that the structure of the spraying device can be simplified.

The catalyst filling device of the present invention includes a spraying device having the above-described configuration, wherein the sprayed material is a catalyst, and the spraying device fills the inside 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 housed inside the cup member, the catalyst is discharged from the discharge port of the cup member regardless of the particle size. To. Since the catalyst discharged from the discharge port is agitated by the stirring blade, the size of the catalyst filled in the reaction column is less unevenly distributed.
Therefore, when the raw material fluid is flowed through the reaction tower after the catalyst is filled and the reaction work is performed, 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.

The present invention includes a control device that sends 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 peripheral portion of the reaction tower with the catalyst at a high density. A high-speed rotation mode in which the cup member and the stirring blade are rotated at high speed, and a low-speed rotation mode in which the cup member and the stirring blade are rotated at low speed in order to fill the central portion of the reaction tower with a coarse density. A signal for switching between and may be sent to the rotation mechanism.
In this configuration, when a high-speed rotation mode signal is sent from the control device to the rotation mechanism, the rotation mechanism causes the cup member and the stirring blade to rotate at high speed. Of the catalysts housed in the cup member, mainly large catalysts are sprayed far from the upper end of the discharge port toward the inner wall of the reaction tower due to a large centrifugal force, and catalysts of different sizes are sprayed far from the discharge port. It falls from the lower end of the to the center and is sprayed. By continuing this state for a long time, the amount of the catalyst filled in the inner peripheral portion of the reaction tower increases, and the high-density catalyst filled in the inner peripheral portion of the reaction tower becomes tubular.
After that, when the control device sends a signal for switching from the high-speed rotation mode to the low-speed rotation mode to the rotation mechanism, the cup member is rotated at a low speed. Most of the catalyst housed in the cup member is sprayed to the central part without reaching the inner peripheral part of the reaction tower from the discharge port due to the reduced centrifugal force. By continuing this state for a certain period of time, the coarse-density catalyst is filled inside the high-density catalyst formed in the tubular shape of the reaction column.
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 thereof.
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 or agitated by the stirring blade rotating with the cup member. Since it is agitated by the airflow generated by the rotation of the blade, the size of the catalyst filled in the reaction tower is less unevenly distributed.

The present invention includes a control device that sends a signal for changing the rotation of the cup member and the stirring blade to the rotation mechanism, and the control device has a forward rotation mode in which the cup member and the stirring blade are rotated in the forward direction. A signal for switching between the cup member and the reverse rotation mode for rotating the stirring blade in the reverse direction may be sent to the rotation mechanism.
In this configuration, when a signal of the forward rotation mode is sent from the control device to the rotation mechanism, the cup member rotates forward and discharges the catalyst from the discharge port into the inside of the reaction tower. At this time, if the cup member is rotated at high speed for a long time, the inner peripheral portion of the reaction tower is filled with a high-density catalyst in a tubular shape. After that, when the control device sends a signal for switching from the forward rotation mode to the reverse rotation mode to the rotation mechanism, the rotation speed decreases from the forward rotation to the reverse rotation of the cup member by the rotation mechanism, and then the cup member stops. After that, it starts to rotate in the reverse direction at a low speed, and after a predetermined time elapses, it rotates at a high speed. Since the cup member is in a low-speed rotation or a stop state over a period from high-speed rotation to stop in forward rotation and a time from stop to high-speed rotation in reverse rotation, the central portion of the reaction tower is filled with a coarse-density catalyst. To.
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 portion of the reaction tower and the coarse-density catalyst filled in the central portion. The inside of the reaction column is filled until and reaches a predetermined height.
Here, when a long member such as a thermometer is arranged inside the reaction tower so as to extend vertically, the catalyst hits from one direction of the member just by rotating the cup member in one direction. The catalyst is less likely to accumulate in the shaded area. Therefore, in this configuration, by repeating the forward rotation and the reverse rotation of the cup member, the part behind the member disappears, and the catalyst can be evenly filled in the reaction tower.

In the present invention, the regulating portion linearly closes a part of the discharging port from the bottom of the peripheral surface of the cup member along the radial direction, and the discharging port is a portion closed by the regulating portion. The control device has a first opening and a second opening on both sides of the sandwiched cup member in the circumferential direction, and the upper end of the first opening is higher than the upper end of the second opening. When the inner peripheral portion of the reaction tower is filled with the catalyst at a high density, the cup member and the stirring blade are rotated in the forward direction so that the catalyst is discharged from the first opening, and the center of the reaction tower is formed. When the portion is filled with the catalyst at a coarse density, the cup member and the stirring blade may be rotated in the reverse direction so that the catalyst is discharged from the second opening.
In this configuration, when a signal of the forward rotation mode is sent from the control device to the rotation mechanism, the catalyst is discharged from the first opening of the cup member that rotates forward and is filled in the reaction tower, so that the signal of the reverse rotation mode is sent. Is sent, the catalyst is discharged from the second opening of the cup member that rotates in the reverse direction, and the reaction tower is filled. Here, since the position of the upper end of the first opening is higher than that of the second opening, when the cup member rotates in the forward direction, the catalyst is sprayed far from the high position of the cup member, and the inner circumference 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. Therefore, even if the cup member is rotated at high speed, it is difficult for the catalyst to reach the inner peripheral portion, which is suitable for filling the central portion with the catalyst. Is.

The present invention includes a hopper that stores the catalyst and a catalyst powder smaller than the catalyst in a mixed manner, and a separation device that separates the catalyst supplied from the hopper from the catalyst powder and sends it to the spraying device. The apparatus includes a catalyst tube in which the catalyst and the catalyst powder coexist and flow, an inner tube arranged inside the catalyst tube, and an outer tube arranged outside the catalyst tube. The pipe has a peripheral surface portion in which a plurality of communication holes through which the catalyst powder can pass and through which the catalyst cannot pass are formed, and the inner pipe discharges the catalyst powder for discharging the catalyst powder from the communication holes. The outer pipe has a wall portion formed with a plurality of fluid supply holes for supplying the fluid for use to the space between the catalyst pipe and the outer pipe, and the outer pipe is the catalyst powder discharged from the communication hole with the catalyst pipe. A vortex generating portion that generates a vortex in the flow of a mixture of the catalyst powder and the catalyst is provided on at least one of the peripheral surface portion of the catalyst pipe and the wall portion of the inner pipe. The fluid supply hole may be provided so as to face at least the position where the vortex is generated in the vortex generation portion.
In this configuration, the catalyst and the catalyst powder stored in the hopper are separated by a separation device, the catalyst powder is discharged to the outside of the separation device, and the catalyst is sent to the spraying device.
In the separation device, a mixture of the catalyst and the catalyst powder flows in the inside of the catalyst tube along the axial direction and hits the whirlpool generating portion to generate a whirlpool. When a vortex is generated in the flow of the mixture, the catalyst powder, which is smaller than the catalyst, stays in a turbulent state.
The fluid for discharging the catalyst powder that flows inside the inner pipe is sent to the inside of the catalyst pipe from the fluid supply hole. Since the fluid supply hole is arranged so as to face the position where the whirlpool is generated in the whirlpool generation portion, the catalyst powder staying in the whirlpool state is pushed out toward the communication hole. Then, the catalyst powder is efficiently discharged to the storage space between the outer pipe and the catalyst pipe through the communication hole. 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 that it continues to flow inside the catalyst tube along the axial direction. Therefore, at least one of the peripheral surface portion of the catalyst pipe and the wall portion of the inner pipe is provided with a vortex generation portion that generates a vortex in the flow of the mixture of the catalyst and the catalyst powder, and the fluid supply hole of the inner pipe and the vortex generation are generated. Since the position where the vortex flow is generated is arranged opposite to the position where the vortex flow is generated, the fluid sent from the fluid supply hole communicates the catalyst powder which is in a turbulent state due to the vortex flow generation part and stays in the vicinity of the vortex flow generation part. The catalyst powder is efficiently discharged into the storage space. On the other hand, since the catalyst itself continues to circulate inside the catalyst tube, the catalyst and the catalyst powder are surely separated.

Therefore, when the main shaft 541A of the air motor 541 is rotated by the air supplied from the air supply source 543, the shaft body 530 rotates together with the main shaft 541A.
The tachometer 542 is attached to the air motor 541, detects the rotation speed of the spindle 541A of the air motor 541, and outputs a signal to the control device 5.
A lighting device 6 and a camera (not shown) are arranged inside the reaction tower 1. The lighting device 6 and the camera are turned ON or OFF in response to a signal from the control device 5.

[Control device]
The control device 5 is connected to an external power source (not shown), receives an output signal from the tachometer 542, and sends a signal to the air motor 541 so that the cup member 52 and the stirring blade 532 rotate properly.
The control device 5 sends a signal to the rotation mechanism 54 to switch between the forward rotation mode in which the cup member 52 and the stirring blade 532 rotate in the forward direction and the reverse rotation mode in which the stirring blade 532 rotates in the reverse direction, and further, the forward rotation mode and the reverse rotation mode, respectively. In, a signal for switching between the high-speed rotation mode and the low-speed rotation mode is sent to the rotation mechanism 54.
In the high-speed rotation mode, the cup member 52 and the stirring blade 532 are rotated at high speed in order to fill the inner peripheral portion A of the reaction tower 1 with a high density of the catalyst, and in the low-speed rotation mode, the central portion B of the reaction tower 1 is rotated. The cup member 52 and the stirring blade 532 are rotated at a low speed in order to fill the catalyst with a coarse density. The high-speed rotation mode may be one in which the time becomes shorter as the forward rotation mode and the reverse rotation mode are switched.
The switching of these modes is executed by the control device 5 through an operation panel (not shown).

[Catalyst filling method]
[Preparation process]
First, the scaffolding 4 is assembled in the reaction tower 1 and the catalyst filling device 3 is installed.
[Separation process]
The mixture 2B is stored in the hopper 11. The mixture 2B is sent from the hopper 11 to the separating device 20.
In the separation device 20, the mixture 2B sent from the hopper 11 flows downward in the space 21A between the catalyst tube 21 and the inner tube 22. Then, of the mixture 2B, the mixture 2B circulating in the portion close to the inner pipe 22 hits the second fin 81 and the flow is obstructed, and the mixture 2B circulating in the portion close to the outer pipe 23 hits the first fin 80. It flows along the upper surface (surface) of the first fin 80 from the base end side to the tip end side. In the mixture 2B, a whirlpool P is generated immediately after the mixture 2B is separated from the tip of the first fin 80. The vortex flow P causes the catalyst powder 2A, which is smaller than the catalyst 2 in the mixture 2B, to turbulently flow. Along with the whirlpool P, the catalyst powder 2A enters and stays in the region Q formed between the lower parts of the first fin 80.

Here, when the dust-removing air is sent to the inside of the inner pipe 22, the dust-removing air is mixed in which the flow is obstructed by the second fin 81 through the fluid supply hole 221 located above the base end of the second fin 61. The object 2B is made to flow backward and sent to the catalyst tube 21 side, and further, the catalyst powder 2A staying below the first fin 80 is pushed out toward the communication hole 211 by the whirlpool P, and the catalyst powder 2A is pushed out together with the dust removing 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 removing air discharge pipe 25 and the exhaust mechanism 26.
When the storage space 23A is sucked by the dust removing 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 forced. It is sent to the storage space 23A through the communication hole 211. Since the catalyst 2 larger than the catalyst powder 2A does not pass through the communication hole 211, it is sent to the downstream side.

[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 catalyst 2 having a mixed size is sent to the inside of the cup member 52 through the inside of the casing 51 of the spraying device 50. After being housed in the cup member 52, the catalyst 2 is discharged to the inside of the reaction tower 1 through the discharge port 52B, and the catalyst 2 in an amount supplementing the discharged catalyst 2 is supplied from the valve 40.
Then, the control device 5 is operated through an operation panel (not shown). For example, through the control device 5, a signal is sent to the rotation mechanism 54 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 the signal from the control device 5, the air supplied from the air supply source 543 rotates the cup member 52 and the stirring blade 53 in the forward direction and at high speed through the air motor 541 and the shaft body 530, and then the air. It is discharged through the discharge pipe 544.

First, when the cup member 52 and the stirring blade 53 rotate forward (clockwise in FIG. 5) and rotate at high speed by the rotation mechanism 54, the catalyst 2 housed in the cup member 52 rotates at high speed together with the cup member 52 by the regulating unit 52M. Therefore, the catalyst 2 having a mixed size is sprayed from the first opening 52B1 into the reaction tower 1. Since the cup member 52 is rotating forward, the catalyst 2 is discharged from the upper end to the lower end of the first opening 52B1, and most of the large catalysts 2 are first due to the large centrifugal force accompanying the high-speed rotation. 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 agitated by the stirring blade 53 rotating together with the cup member 52, or by the air flow generated by the stirring blade 53. Indirectly agitated. A small amount of the agitated catalyst 2 will be sprayed on 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. To do. Since the centrifugal force of the catalyst 2 sprayed 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. By the steps from high-speed rotation to low-speed rotation and further to stop, the catalyst 2 in which the size is mixed is sprayed downward from the lower end of the first opening 52B1, but is stirred by the stirring blade 53. become. As a result, the upper surface of the filled catalyst 2 becomes a line L11 that is highest on the inner wall side of the reaction tower 1 and inclines downward along the axis (see FIG. 1).

Further, 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 reverses the cup member 52 and the stirring blade 53 from the stopped state. The catalyst 2 is switched to low-speed rotation for a predetermined time in the direction, and the catalyst 2 housed in the cup member 52 is sprayed from the second opening 52B2 toward the central portion B while being stirred by the stirring blade 53. After that, the rotation is switched from low speed to 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 is high speed, the upper end of the second opening 52B2 There are few catalysts 2 that reach the side wall of the reaction tower 1. As a result, the upper surface of the filled catalyst 2 becomes the line L1 which is the highest on the inner wall side of the reaction tower 1 as compared with the line L11 and is inclined downward along the axis (see FIG. 1).
Here, when long members (not shown) such as a thermometer are arranged vertically inside the reaction tower 1, if the cup member 52 is rotating in the forward direction, only one direction is applied to the long member. Therefore, the catalyst 2 is hit, and the portion behind the long member is not sufficiently filled with the catalyst 2. However, when the cup member 52 rotates in the reverse direction, the catalyst 2 is filled in a portion behind 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 causes the cup member 52 and the stirring blade 53 to once rotate from the high-speed rotation. After stopping, it switches to high-speed rotation in the forward direction. Then, the catalyst 2 housed in the cup member 52 is sprayed from the second opening 52B2 toward the central portion B at the time of stopping and at the time of low speed rotation immediately before the stop, and further at the time of stopping and at the time of low speed rotation immediately after that. It is sprayed from the first opening 52B1 toward the central portion B. When the cup member 52 rotates at high speed in the forward direction, a large catalyst 2 is mainly discharged from the upper end portion 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, again, the rotation mechanism 54 stops the cup member 52 and the stirring blade 53 after switching from high-speed rotation to low-speed rotation, and most of the large and small catalysts 2 are sprayed on the central portion B. Through the steps from high-speed rotation to low-speed rotation and further to stop, the catalyst 2 having a mixed size is sprayed downward from the lower end of the first opening 52B1 and is agitated by the stirring blade 53. As a result, the inside of the reaction tower 1 is filled with the catalyst 2 along the line L2.
By repeating the above modes, a high-density catalyst 2 is formed in the inner peripheral portion A of the reaction tower 1 over a predetermined height, and a coarse-density catalyst 2 is formed in the central portion B over a predetermined height. It is formed. Further, the catalyst 2 is filled so that the upper surface is along the line L2, the line L3, the line L4, ..., The line LN, and finally, the amount of the catalyst 2 filled in the central portion B is adjusted. The catalyst 2 is filled on the line LN so that the upper surface becomes a flat line LT. In the present embodiment, the time for rotating the cup member 52 and the stirring blade 53 may be set shorter as the bottom of the reaction tower 1 is filled and the lines L1, L2, L3, L4, ... LN are stacked. ..

Further, in the present 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 sprayed from the first opening 52B1 to form a tubular inner peripheral portion A, and when the cup member 52 rotates in the reverse rotation mode, Large and small catalysts 2 are sprayed from the second opening 52B2 to form the central portion B. When the central portion B is formed, the large and small catalysts 2 are agitated and made uniform by the stirring blade 53.
Further, in order to fill the inner peripheral portion A with the catalyst 2 at a high density and the central portion B with the catalyst 2 at a coarse density, the catalyst 2 is deposited in a tubular shape along the inner wall of the reaction tower 1 and the cylinder 2 is deposited. A part of the catalyst 2 deposited in the shape may be naturally dropped, and the dropped catalyst 2 may form the central portion B. In this case, the amount of the catalyst 2 sprayed from the cup member 52 is reduced in order to form the central portion B.

[Reaction process]
When 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 filled 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 each of the inner peripheral portion A and the central portion B, particularly in the central portion B, Since the large and small catalysts 2 are uniformly filled, the raw material fluid flows in regardless of the position where the catalyst is filled, for example, the central portion B or the inner peripheral portion A of the reaction tower 1.

[Action and effect of the embodiment]
In the present embodiment as described above, the following effects can be obtained.
(1) A cup member 52 in which a discharge port 52B for storing the catalyst 2 as a spray material having a different particle size and discharging the catalyst 2 is formed between the bottom and the opening edge, and a catalyst housed in the cup member 52. A regulating unit 52M that regulates the relative movement of the 2 to the cup member 52, a stirring blade 53 that agitates 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. The spraying device 50 was configured with the above. Therefore, the catalyst 2 having a large particle size is mainly sprayed far away from the portion of the discharge port 52B near the upper end due to a large centrifugal force, and the catalyst having a mixed size is mixed from the portion near the bottom. 2 is sprayed downward, but since the catalyst 2 is agitated by the stirring blade 53 that rotates together with the cup member 52, the uneven distribution of the size of the catalyst 2 is reduced.

(2) The regulation portion 52M was formed by fixing the regulation plate portion 534 to the first shaft portion 533, and the stirring blade 532 was formed by fixing the stirring plate portion 536 to the second shaft portion 535. Therefore, by rotationally driving 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 spraying device 50 can be simplified. Can be made into something.
(3) Since the control device 5 for sending a signal for changing the rotation of the cup member 52 and the stirring blade 53 to the rotation mechanism 54 is provided, the spraying place of the catalyst 2 discharged from the discharge port 52B can be easily set. it 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 52B1 and a second opening 52B2 on both sides of the portion linearly closed by the regulating portion 52M, and the upper end of the first opening 52B1 is the second opening. The position is higher than the upper end of the portion 52B2 so that the catalyst 2 is discharged from the first opening 52B1 when the control device 5 is filled with the catalyst 2 at a high density in the inner peripheral portion A of the reaction tower 1. When the cup member 52 and the stirring blade 53 are rotated in the forward direction and the central portion B of the reaction tower 1 is filled with the catalyst 2 at a coarse density, the cup member 52 and the stirring blade 52 are stirred so that the catalyst 2 is discharged from the second opening 52B2. The wing 53 is configured to rotate in the reverse direction. Therefore, when the cup member 52 rotates in the forward direction, the catalyst 2 is sprayed far from the high position of the cup member 52, which is effective when the inner peripheral portion A is filled with the high-density catalyst 2. .. 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. Therefore, even if the cup member 52 is rotated at a high speed, the catalyst 2 is difficult to reach 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 filling device 3 is provided with the spraying device 50 having the above-described configuration, the catalyst 2 filled in the reaction tower 1 has a size in each of the inner peripheral portion A and the central portion B thereof. There is less uneven distribution. Therefore, when the raw material fluid is flowed through the reaction tower 1 after the catalyst is filled and the reaction work is performed, the raw material fluid flows in the same manner regardless of the position of the reaction tower 1, so that 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 rotation mechanism 54 for switching between a high-speed rotation mode in which the cup member 52 and the stirring blade 53 are rotated at high speed and a low-speed rotation mode in which the cup member 52 and the stirring blade 53 are rotated at low speed. Therefore, a high-density catalyst 2 is formed over a predetermined height in the inner peripheral portion A of the reaction tower 1, and a 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 rotation mechanism 54 to switch between a forward rotation mode in which the cup member 52 and the stirring blade 53 are rotated in the forward direction and a reverse rotation mode in which the cup member 52 and the stirring blade 53 are rotated in the reverse direction. Therefore, when long members such as thermometers are arranged vertically inside the reaction tower 1, by repeating forward rotation and reverse rotation of the cup member 52, the part behind the long member disappears. , The catalyst 2 can be evenly filled in the reaction column 1.

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

(11) The whirlpool generating portion 8 has a first fin 80 whose tip is directed to the downstream side in the distribution direction of the mixture 2B, and is 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 mixture 2B flows, when the mixture 2B hits the first fin 80, the catalyst powder 2A wraps downward from the tip of the first fin 80 to generate a whirlpool P. The catalyst powder 2A that has become turbulent due to the vortex flow P is surely sent out to the storage space 23A by the dust removing air, and is surely separated from the catalyst 2. Therefore, the whirlpool P can be reliably generated, and the configuration of the whirlpool generation unit 8 can be simplified.
(12) Since the first fin 80 is formed in an annular shape centered on the axis of the catalyst tube 21, there is no portion where the first fin 80 is missing along the circumferential direction, and a mixture of the first fin 80. A 2B whirlpool can be reliably generated.
(13) Since the second fin 81 that obstructs the flow of the mixture 2B along the outer peripheral surface is provided on the outer periphery of the inner pipe 22, the mixture 2B is agitated and the whirlpool P is surely 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 and the catalyst pipe 21 The catalyst powder 2A inside can be forcibly sent out to the storage space 23A, and from this point as well, the catalyst powder 2A and the catalyst 2 can be separated more reliably.

For example, in the above embodiment, the cup member 52 is configured to include a cup body 521 having a hemispherical outer circumference and an inner circumference and a lid member 522, but in the present invention, the cup member 52 is as shown in FIG. The 520 may be configured to include a bottomed cylindrical cup 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 on the disc portion 523A, or may be formed from the disc portion 523A to the cylinder portion 523B. As the cup member 52 shown in FIG. 7, the stirring blade 53 shown in FIG. 4 may be used. As shown in FIG. 4, the regulation plate portion 534 of the regulation portion 52M may have a fan shape, or may have a flat rectangular shape according to the internal shape of the cup body 523.

Further, in the above-described embodiment, the regulating plate portion 534 and the stirring plate portion 536 each have a flat rectangular shape, but in the present invention, as shown in FIG. 8, a flat fan shape may be used. In this case, the straight portion forming the fan shape 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.

Further, in the above-described embodiment, the regulation unit 52M and the stirring blade 532 are connected to each other, but in the present invention, the structure may be separated and rotationally driven by a drive mechanism. Further, a rotating body (not shown) that rolls may be provided on the outer circumference of the cup member 52, and this rotating body may be used as a rotating mechanism.
Further, the discharge port 52B is formed in a slit shape along the radial direction from the bottom of the cup member 52, but 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 in the radial direction from the center of the bottom. Even when 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 embodiment, and is formed in a spiral shape from the bottom of the cup member 52 toward the opening edge. It may be a thing.

In the above embodiment, the discharge port 52B is formed separately for the first opening 52B1 and the second opening 52B2 having different upper end positions, but in the present invention, the discharge port 52B may be formed separately for the same opening. The first opening 52B1 and the second opening 52B2 may each have a shape in which the bottom side of the cup member 52 is larger than the opening end.
Further, in the present invention, the control device 5 may omit switching between the forward rotation mode and the reverse rotation mode, and may be configured to send only a switching signal between the high-speed rotation mode and the low-speed rotation mode to the rotation mechanism 54.
Further, in the present invention, the density of the catalyst 2 filled in the reaction tower 1 may be uniform regardless of the inner peripheral portion A and the central portion B.

Is exposed inside the reaction tower 1, but in the present invention, these stirring plate portions 536 may be connected to each other by a plate portion orthogonal to the shaft core of the second shaft portion 535. By connecting with the plate portion, the strength of the stirring blade 532 becomes large. However, as in the above embodiment, if the plurality of stirring plate portions 536 are configured such that the peripheral edges of the three sides excluding the base end side in contact with the second shaft portion 535 are exposed inside the reaction tower 1, the plate portion Since the catalyst 2 is less likely to fall onto the plate portion and be blown to the vicinity of the wall portion of the reaction tower 1 by the centrifugal force of the plate portion, the deviation of the particle size of the sprayed catalyst 2 can be made smaller.

In the present invention, the separation device 20 may be omitted.
Even if the separation device 20 is provided, the configuration is not limited to that of the embodiment. For example, the second fin 81 may be omitted, and further, the first fin 80 and the second fin may be omitted. It is not necessary to configure 81 from a plurality of stages, and it may be configured from one stage.
Further, the material to be sprayed of the present invention is not limited to the catalyst 2 sprayed inside the reaction tower 1, and for example, granules used in the metal field such as aluminum powder, zinc powder, and alloy powder. Granules used in the chemical field such as carbon powder, activated carbon, resin powder, resin beads, granules used in the ceramic industry such as alumina and clay, and used in the food field such as salt, fine sugar and granulated sugar. It may be a granular material or a granular material used in other fields.
