In this embodiment, the internals consist of three parts, namely a redistributor 1, a partition 3 and a guiding orifice 2. Wherein the redistributor 1 is used for increasing the residence time of the gas phase and the solid phase in the fluidized bed and breaking up large bubbles so as to strengthen the disturbance action of the gas phase and the solid phase in the fluidized bed. The guiding pore plate 2 is used for re-increasing the residence time of the gas phase and the solid phase in the fluidized bed, enhancing the disturbance action of the gas phase and the solid phase in the fluidized bed, weakening the aggregation and separation of the gas phase and the solid phase caused by swinging, and avoiding the local dead zone caused by the accumulation of the gas phase and/or the solid phase on one side of the fluidized bed due to the swinging of the fluidized bed. The vertical partition plate 3 is used for weakening the gas phase and the solid phase from aggregation and separation caused by swing, and avoiding local dead zone caused by gas phase and/or solid phase accumulation on one side of the fluidized bed due to the swing of the fluidized bed.
Specifically, the redistributor 1 includes a mount 11, a fixed frame 12, and a plurality of swirl plates 13. Alternatively, the mounting member 11 has a frame structure, and the shape of the mounting member corresponds to that of the fluidized bed, and may be a round frame or a square frame. The mounting member 11 is disposed in the fixed frame 12, and the mounting member 11 is disposed concentrically with the fixed frame 12, and the swirl plate 13 is connected between the mounting member 11 and the fixed frame 12. Alternatively, the shape of the fixing frame 12 corresponds to the shape of the mounting member 11, and if the mounting member 11 is a circular frame, the fixing frame 12 is also a circular frame. In this embodiment, two ends of the swirl plate 13 are respectively connected with the mounting member 11 and the fixing frame 12, and all the swirl plates 13 are uniformly distributed along the edge of the mounting member 11, and at the same time, the swirl plate 13 is a swept plate.
In this embodiment, by providing a plurality of swirl plates 13, at the same time, since two adjacent swirl plates 13 are disposed at intervals, the gaps 32 between two adjacent swirl plates 13 can crush the large bubbles one by one, and the gas phase plays a role of redistribution, so that the gas phase entering the reaction section is uniformly distributed.
Also, the swirl plate 13 is provided in a glancing arrangement so that it can change the travel paths of the gas phase and the solid phase (normal gas phase and solid phase travel along the axial direction of the fluidized bed), increasing the action time of the gas phase and the solid phase within the fluidized bed.
In this embodiment, the two ends of the guiding orifice plate 2 are respectively flush with the two ends of the reaction section in the fluidized bed, and the guiding orifice plate 2 is in a glancing structure, so that the gas phase and the solid phase can move continuously along the extending direction of the guiding orifice plate 2 in the reaction section, the acting time of the gas phase and the solid phase in the fluidized bed can be increased again, and the disturbance of the gas phase and the solid phase in the fluidized bed is enhanced.

Meanwhile, the radial mixing of the gas phase and the solid phase in the small cavity can be promoted, and the mixing efficiency of the gas phase and the solid phase is improved.
In this embodiment, the guide plate is provided with a first through hole 21. When the fluidized bed swings, the first through holes 21 can crush large bubbles, and as gas phase and solid phase can pass through the first through holes 21, the mixing between the gas phase and the solid phase between different guide pore plates 2 (between two adjacent small cavities) can be promoted under the action of the swing of the fluidized bed, and the mixing efficiency of the gas phase and the solid phase is improved.
In this embodiment, a plurality of spacers are distributed at intervals along the radial direction of the redistributor 1, each spacer is composed of a plurality of spacers 3 disposed at intervals, and solid phase orientation aggregation separation due to swing can be reduced by disposing a plurality of spacers 3. Because the interlayer is composed of a plurality of partition boards 3 which are arranged at intervals, a gap 32 is arranged between two adjacent partition boards 3 of the same interlayer, and the gap 32 can promote the mixing of gas phase and solid phase at two sides of the interlayer and enhance the contact between the gas phase and the solid phase.
In this embodiment, the partition plate 3 and the guide orifice plate 2 cover the reaction section of the whole fluidized bed along the axial direction of the fluidized bed, and meanwhile, due to the overlapping area between the partition plate 3 and the guide orifice plate 2, the partition plate 3 and the guide orifice plate 2 can be connected together by forming avoiding grooves/holes in the partition plate 3 and/or the guide orifice plate 2.
As shown in fig. 1 and fig. 2, the internal components provided by the embodiment of the invention are two redistributors 1, two redistributors 1 are arranged at intervals, and the two redistributors 1 are distributed at two ends of the partition plate 3 and the guide pore plate 2.
In the present embodiment, it is preferable that the redistributors 1 are provided in two, and the two redistributors 1 are provided at a spacing, and the two redistributors 1 are provided at both ends of the partition plate 3 and the guide hole plate 2, respectively. The redistributor 1 can change the flow direction of the gas phase and the solid phase, break up large bubbles, redistribute the gas phase and simultaneously play a role of fixing the guide pore plate 2 and the partition plate 3.
Alternatively, in the present embodiment, the redistributors 1 and the partition plates 3 and the guide hole plates 2 may be connected by a fixed connection such as welding, or may be connected by a detachable connection such as bolting.
Further, in the present embodiment, by providing two redistributors 1, the residence time of the gas phase and the solid phase in the fluidized bed can be further increased, and the disturbance of the gas phase and the solid phase mixture can be accelerated.
Alternatively, in the present embodiment, it is also possible to continue to arrange a redistributor 1 between the two redistributors 1 for increasing the residence time of the gas phase and the solid phase in the fluidized bed, accelerating the disturbing action of the gas phase and the solid phase mixture.
As shown in FIG. 3, the inner member provided by the embodiment of the invention is provided with a gap 32 between two adjacent partition boards 3 in the same interlayer; the gaps 32 of two adjacent spacers are staggered.
In the present embodiment, it has been mentioned that the same partition layer is composed of a plurality of partition plates 3 arranged at intervals, and that a gap 32 is necessarily provided between two adjacent partition plates 3 due to the interval arrangement of the partition plates 3. In this embodiment, the gaps 32 between two adjacent spacers are staggered, so that the gas phase and the solid phase on the inner and outer sides of the separator 3 can be promoted to be mixed while the solid phase aggregation and separation effect caused by the swing of the fluidized bed can be weakened by staggering the gaps 32 between the two spacers. At the same time, this gap 32 is also capable of breaking up large bubbles.
The inner member provided by the embodiment of the invention has opposite twisting directions of the guide pore plate 2 and the swirl plate 13 along the radial direction of the fluidized bed.
In the present embodiment, the above has been mentioned, and the guide orifice plate 2 and the swirl plate 13 are both of a swept-type structure, that is, formed by twisting; in this embodiment, the direction of the fluidized bed is preferably opposite to the direction of the swirl plate 13, so that the paths of the gas phase and the solid phase in the fluidized bed can be forcibly changed, the action time of the gas phase and the solid phase in the fluidized bed can be prolonged, the disturbance action of the gas phase and the solid phase in the fluidized bed can be enhanced, and the gas phase and the solid phase can be accelerated to mix.
Specifically, after the gas phase and the solid phase enter the fluidized bed through the redistributor 1 at the lower end, the gas phase and the solid phase have one rotation direction, such as clockwise, under the action of the redistributor 1; the gas phase and the solid phase continue to advance, the rotation direction is forcedly changed from clockwise to anticlockwise under the action of the guide pore plate 2, and the gas phase and the solid phase need more time to leave the fluidized bed due to the change of the rotation direction of the gas phase and the solid phase, so that the action time of the gas phase and the solid phase in the fluidized bed is prolonged.
As shown in FIG. 4, the inner member provided in the embodiment of the present invention is a curved plate, and the partition plate 3 is provided with a second through hole 31.
In this embodiment, optionally, the partition 3 is a curved plate, which can better conform to the shape of the fluidized bed on one hand, and has a guiding function for guiding the gas phase and the solid phase to move in the fluidized bed on the other hand.
In this embodiment, the second through holes 31 are further formed in the partition plate 3, and the second through holes 31 are used for opening the inner side and the outer side of the partition plate 3, so that the solid phase aggregation separation effect caused by the swing of the fluidized bed can be weakened, and meanwhile, the solid phases on the inner side and the outer side of the partition plate 3 can be dredged, and the gas phase and the solid phase on the inner side and the outer side of the partition plate 3 can be promoted to be mixed. Meanwhile, the second through holes 31 are also capable of breaking up large bubbles.
Preferably, as shown in fig. 4, the second through hole 31 has an elongated shape and extends in the axial direction of the fluidized bed.
In this embodiment, the second through holes 31 are elongated and extend in the axial direction of the fluidized bed to better promote the mixing of the gas phase and the solid phase on both the inner and outer sides of the partition 3.
As shown in FIG. 3, the second through holes 31 of two adjacent spacers are staggered.
In this embodiment, the second through holes 31 of two adjacent spacers are staggered, so that the solid phase aggregation and separation effect caused by the swing of the fluidized bed can be better weakened, and the gas phase and solid phase mixing at the inner side and the outer side of the separator 3 is promoted without influence.
The inner member provided by the embodiment of the invention, as shown in fig. 5, the redistributor 1 further comprises a reinforcing frame 14; the reinforcing frame 14 is disposed between the mounting member 11 and the fixing frame 12, and all the swirl plates 13 are connected to the reinforcing frame 14.
In this embodiment, the reinforcing frame 14 is used to improve the connection strength of the swirl plate 13 of the redistributor 1, and at the same time, the reinforcing frame 14 can also form a plurality of holes on the redistributor 1, under the action of the holes, large bubbles can be broken, so that the gas phase enters the reaction section more uniformly, and the contact efficiency of the gas phase and the solid phase is improved.
In the present embodiment, the reinforcing frame 14 is provided in a shape corresponding to the mount 11 and the fixed frame 12, and the reinforcing frame 14 is provided concentrically with the mount 11 and the fixed frame 12.
In the present embodiment, the reinforcing frame 14 may be fixed to the swirl plate 13 by welding, or by a connection such as a bolt connection.
In this embodiment, the guiding perforated plate 2 is provided with a plurality of second through holes 31 which are uniformly distributed.
The internals provided in the present embodiments are exemplified by a mixture of standard air and FCC catalyst particles. Among these, the main components of FCC catalyst particles are alumina, silica, some amount of rare earth and very few other elements, which are well known in the art.
In this embodiment, the partition is provided with two layers, each layer of partition includes three partition plates 3, and four guide hole plates 2 are provided.
In this embodiment, the second through holes 31 on the partition plate 3 near the partition plate of the axial center of the redistributor 1 are not shown in the figure.
When the air pump is used, firstly, the air pump is started, the rotameter is regulated to the required air quantity, at the moment, standard air uniformly enters the bottom of the bed body through the air distribution plate, the quantity of FCC catalyst particles moving along with the standard air is gradually increased along with the continuous rising of the air, when the air pump reaches the position of the redistributor 1 positioned below, partial converged large bubbles are broken through the redistributor 1, at the moment, partial FCC catalyst particles are lifted by the air, the height of the bed layer is lifted to a certain degree, under the action of the redistributor 1, the movement directions of the FCC catalyst particles and the standard air are changed, the movement path of the FCC catalyst particles is longer than that of the FCC catalyst particles moving along the axial direction of the fluidized bed, the stay in the fluidized bed is longer, and the disturbance action of the FCC catalyst particles and the standard air in the fluidized bed is enhanced. At the same time, since the fluidized bed swings with the ship or the swing platform when in use, FCC catalyst particles and standard air are also radially displaced and mixed through the gaps between the partition plates 3, the second through holes 31 on the partition plates 3, and the first through holes 21 on the guide orifice plate 2. Meanwhile, the direction of the FCC catalyst particles and the movement direction of the standard air are changed again under the action of the guide orifice plate 2 due to the opposite direction of the guide orifice plate 2 and the opposite direction of the redistributor 1, so that the residence time in the fluidized bed is forcedly prolonged, and the disturbance action of the FCC catalyst particles and the standard air in the fluidized bed is further enhanced. After the FCC catalyst particles and the standard air are mixed radially through multiple secondary shafts, the particles are crushed again by the redistributors 1 positioned above, and the movement direction is forcedly changed again, so that the residence time in the fluidized bed is increased again, and the disturbance effect of the FCC catalyst particles and the standard air in the fluidized bed is enhanced. Eventually, FCC catalyst particles and standard air flow out of the top of the fluidized bed.
By adding the internal components in the embodiment, when the gas phase passes through the bottom redistributor 1, the gas moves along the rotation direction of the redistributor 1, the residence time of the gas phase in the bed layer is prolonged, and under the action of the reinforcing frame 14, the gas phase and the solid phase are promoted to be disturbed in the fluidized bed, large bubbles are broken, and the gas phase and the solid phase are primarily promoted to be mixed; along with the further rising of the gas phase, after entering the vertical areas of the guide pore plate 2 and the partition plate 3, the gas phase moves along the different rotation directions from the gas phase passing through the redistributor 1 due to the different twisting directions of the guide pore plate 2 and the bottom redistributor 1, and at the moment, the movement of the solid phase also changes, so that the disturbance effect of the gas phase and the solid phase is further improved. In addition, the first through holes 21 are arranged on the guide pore plates 2, so that the gas phase and solid phase mixing effect between different guide pore plates 2 can be enhanced, and large bubbles can be crushed; in addition, the presence of the partition plate 3 can break up large bubbles, inhibit radial mixing of the solid phase, and reduce the gas-solid phase separation effect caused by swing of the fluidized bed. Finally, the gas passes through the upper redistributor 1 to strengthen the residence time of the gas in the fluidized bed again, accelerate the disturbance action of the gas-solid two-phase mixture, promote the contact of the gas phase and the solid phase and strengthen the reaction efficiency.
In another aspect, the present invention provides a fluidized bed comprising the inner member of any one of the above embodiments.
