動層によつて吸着除去するために用いられる。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a moving bed reactor, in particular a moving bed in which particles are moved from above to below is laterally supported by louvers, and a gas is passed across the moving bed between the louvers. This invention relates to a moving bed reactor. This type of moving bed reactor is used, for example, to adsorb and remove sulfur dioxide gas contained in exhaust gas from a boiler or the like using an adsorbent moving bed.

出て反応器４外に排出される。 Conventionally, when gas is aerated through a packed bed of particulate adsorbent, catalyst, or other particles, and the components in the gas are brought into contact with the particles for reaction or collection, a louver 1 as shown in Fig. 1 is used. A moving bed type packed bed is used in which particles 2 are supported by a pair of louvers 1 arranged vertically in large numbers. The exhaust gas 3 is introduced into the reactor 4, passes through the moving bed from the side of the louver 1, comes into contact with the particles, and then exits the other louver and is discharged to the outside of the reactor 4.

で濡れてくるようになり、ルーバ１を腐蝕させる
という問題がある。 However, in the moving layer supported by such a louver 1, a part 1A where particles do not move is formed on the louver 1, as shown in FIG. Therefore, when the gas to be handled contains a large amount of dust, such as the exhaust gas of a coal boiler, there is a drawback that the dust gradually accumulates in the non-moving portion 1A, increasing ventilation loss. In addition, when sulfur dioxide gas in gas is adsorbed with a carbon-based adsorbent such as activated carbon, the adsorbent in the non-moving part 1A adsorbs sulfur dioxide gas to more than saturation level over a long period of time, causing the adsorbent to absorb There is a problem in that the surface becomes wet with sulfuric acid generated from the adsorbed sulfur dioxide gas, corroding the louver 1.
本発明の目的は、ルーバ上に粒子が滞留するこ

置を提供することにある。 An object of the present invention is to provide a moving bed reactor that can satisfactorily move particles on the louvers without causing particles to remain on the louvers, and can prevent gas ventilation loss.

うにしたものである。 In the conventional louver 1, as shown in FIG. 2, the load exerted in the horizontal direction by the mainstream particle group 5 balances the load on the non-moving part 1A, so that as a result, the particles in the non-moving part 1A become the main stream. In order to make it clear by the flow of colored particles that they no longer flow into the particle group 5, and to destroy this load balance,
A sub-louver with a larger inclination angle is provided inside the louver 1, and the non-moving part is moved through this sub-louver.
It is designed to effectively flow 1A particles into the mainstream.

る。 The present invention provides a moving bed reactor in which a moving bed that moves particles from above to below is supported from the side by a main louver and a sub-louver provided inside the main louver, and a gas is passed across the moving bed between the louvers. A sub-louver, which is also vertically aligned in the vertical direction, is arranged inside the main louver which is vertically aligned in a line, so as to be located in the middle of the main louver in the height direction, and between the main louver and the sub-louver. The angle with the horizontal is 40 to 80 degrees,
The sublouver is characterized in that the angle it makes with the horizontal is larger than that of the main louver, and the length of the sublouver is 2/3 to 4/5 of that of the main louver.

This is to reduce the load of particles from the upper part. The length of the above sublouver B
is about 2/3 to 4/5 of the main louver (especially around 3/4)
is suitable. Note that the angle between the two louvers and the horizontal is greater than the angle of repose of the particles, usually about 40 to 80 degrees.
A range of is appropriate.

る。 FIG. 3 is an explanatory view showing an embodiment in which the reaction apparatus of the present invention is applied to an adsorbent-filled bed for non-smoke desulfurization, and FIG. 4 is an enlarged side view of the louver portion thereof. Adsorption tower 20
Inside the tower, main louvers 6 and sub-louvers 7 are arranged vertically in pairs from the bottom to the top of the tower, and these pairs are arranged in two rows at a certain distance, and between these two rows of louvers. Adsorbent 8 is filled. Further, a vertical guide plate 14 is provided on the lowest louver at the bottom of the adsorption tower, and a guide plate 15 is further provided below the vertical guide plate 14.
is provided to prevent stagnation of adsorbent due to dead space. Note that a flow regulator 16 is provided at the hopper portion to promote smooth flow. Exhaust gas 9 from a boiler or the like flows into the adsorption tower 20 from the gas inlet 10, enters the adsorbent packed bed through the gap in the louver, and flows out from the gas outlet 11 through the gap in the other louver. During this time, sulfur dioxide gas in the gas is adsorbed and removed. As the adsorbent reaches saturation as time passes, the adsorbent that has reached the bottom of the adsorption tower is removed from the extractor 1.
2, a certain amount is continuously extracted, and after being regenerated by a regenerating device (not shown here),
It is supplied from the hopper into the packed bed and recycled.

ができた。 The details of this louver system are as shown in Fig. 4. Inside the main louvers 6, which are vertically lined up in a row, sub-louvers 7, which are also vertically lined up, are arranged in the height direction of the main louvers. It is arranged so as to be located in the middle, and the angle θ 2 between the sub louver and the horizontal direction is larger than the angle θ 1 of the main louver. The dimensions of each part of the louver are as follows: A part of the main louver 6 is 200 mm, B part of the sub louver 7 is 150 mm, θ 1 is 60 degrees, θ 2 is 74 degrees, the gap C of the main louver 6 is 200 mm, and the lower end of the main louver 6 The vertical distance D between the upper end of the main louver 6 and the upper end of the sub louver 7 is 28.1 mm, the horizontal distance E between the lower end of the main louver 6 and the upper end of the sub louver 7 is 0 to 10 mm, and the horizontal distance F between the lower end of the main louver 6 and the lower end of the sub louver 7 is 35.5 mm. When we filled the space between these louvers with crushed carbon-based adsorbent with a particle size of 5 to 10 mm, pulled it out from below, and moved it, there was no non-movable part on the main louver, and there was no non-movable part on the sub-louver either. Parts were barely recognizable. It was also found that the adsorbent particles moved more smoothly on the louver compared to the case where the sub-louver was arranged parallel to the main louver. In addition, as shown in FIG.
5, there was no dead space in this part, and particle accumulation at the bottom of the column could be prevented.

なり、粒子の滞留は全く見られなくなつた。 Next, FIG. 5 shows a side view of the louver portion of an adsorbent packed tower showing another embodiment of the present invention, but the difference from the embodiment of FIG. 4 is that the sublouver 7
The inclination angle θ 2 of is set to 76°, and the vertical distance D is set to 30 mm, and the horizontal distance F is set to 40 mm. By arranging the louvers in this manner, the movement of the adsorbent on the main louver was made smoother, and no accumulation of particles was observed.

In the above example, the louver length B and vertical distance D were selected so that the horizontal filling pressure was approximately 500 kg/m 2 .

バの腐食を防止することができる。 As described above, according to the present invention, by arranging the sub-louver with a larger horizontal angle above the main louver in a moving bed type packed bed, it is possible to eliminate the part where particles do not move on the louver, and in particular, the sub-louver can be arranged in parallel. The movement of particles can be made smoother than in the case where the particles are arranged. Therefore, dust in the exhaust gas does not continue to accumulate on the louver, and
Even when the adsorbent adsorbs sulfur dioxide gas in the gas, the adsorbent can be moved downward before it adsorbs more than the saturated amount of sulfur dioxide gas, so corrosion of the louvers can be prevented.
