Description

Technical Field

[0001] The utility model relates to the technical field of anti-disproportionate fixed beds, in particular to a device for improving the redundancy of the use cycle of anti-disproportionate fixed beds. Background Art

[0002] After the polysilicon reduction tail gas is treated by the dry recovery system, the separated hydrogen, chlorosilane, etc. are returned to the production system for reuse. The by-product dichlorosilane produced in the reduction reaction is a flammable and explosive gas and needs to be recovered using a deprotonation device.

[0003] The feed inlet and the discharge port of the existing deproportionation reactor are both equipped with water caps to prevent the ion exchange solid resin in the deproportionation reactor from leaking out with the material and being carried to the subsequent system. When the water cap is damaged, the pipelines and filters of the subsequent system will be blocked, and the device needs to be shut down for maintenance, resulting in a shorter operation cycle of the device and more likely to cause unnecessary economic losses. In addition, since the resin in the reactor and the material entering the reactor are in gaseous and solid contact, and the material needs to pass through the dense wire mesh that blocks the resin, the material and the resin cannot be fully contacted, resulting in a slow reaction speed between the material and the resin, resulting in a low conversion efficiency of the reactor.

[0023] like Figures 1 to 4As shown, the device for improving the redundancy of the service cycle of the anti-disproportionation fixed bed in this embodiment includes a reactor 1, wherein a cavity is provided inside the reactor 1 for containing the reaction material and the resin catalyst so that the two have enough space to react in the reactor 1, a top pipe 4 is penetrated on one side of the top of the reactor 1, a first intercommunication pipe 2 is penetrated on the top of the top pipe 4, a bottom pipe 11 is penetrated on one side wall of the bottom of the reactor 1, the top pipe 4 and the bottom pipe 11 have the same diameter, are communicated with the inside of the reactor 1, and can also serve as an inlet and outlet channel for materials, a second intercommunication pipe 7 is penetrated on the bottom end of the bottom pipe 11, and a first intercommunication pipe 2 is penetrated on the top end of the top pipe 4. The first interconnecting pipe 2 and the second interconnecting pipe 7 can make the top pipe 4 and the bottom pipe 11 be connected in an emergency when resin leakage occurs in the reactor 1, so that the material flow direction in the top pipe 4 and the bottom pipe 11 can be switched in time, thereby avoiding continuous leakage of resin into the pipeline of the system to cause pipeline blockage, and reducing unnecessary economic losses. A reaction bed 12 is fixedly installed inside the reactor 1. The reaction bed 12 is composed of a wire mesh and an internal resin catalyst. A vertical rod 13 is movably penetrated in the middle of the reaction bed 12. The top and bottom ends of the vertical rod 13 both pass through the top and bottom of the reaction bed 12, so that The blades 14 can rotate freely in the reactor 1. The top and bottom ends of the vertical rod 13 are fixedly connected with the blades 14. The horizontal heights of the two blades 14 are respectively the same as the horizontal heights of the top pipe 4 and the bottom pipe 11, so that the material flow entering from the top pipe 4 or the bottom pipe 11 can impact the blades 14, prompting the blades 14 to rotate in the reactor 1, thereby realizing that the vertical rod 13 drives the stirring rod 16 to rotate in the reactor 1. The outer walls of the top and bottom of the vertical rod 13 are both engaged with the stirring rod 16. The surface of the stirring rod 16 is smooth and not easy to adhere to substances. At the same time, the stirring rod 16 rotates When the reaction is complete, the material can be driven to fully contact and react with the resin catalyst in the reaction bed 12. The middle of the inner walls on both sides of the reactor 1 are fixedly connected with cross frames 17. The function of the cross frames 17 is to maintain the stability of the vertical rod 13 when it rotates in the reactor 1, so that the horizontal heights of the top and bottom ends of the vertical rod 13 do not change, so that the blades 14 on the vertical rod 13 can continue to be driven to rotate by the incoming high-speed material flow. Water caps 15 are installed at the intersections of the top pipe 4 and the bottom pipe 11 with the reactor 1. The function of the water caps 15 is to prevent the resin in the reaction bed 12 from leaking out from the top pipe 4 and the bottom pipe 11.

[0024] Specifically, the outer wall of the top pipe 4 is respectively installed with the first main valve 5 and the second main valve 6. The intersection of the first interconnecting pipe 2 and the top pipe 4 is located between the first main valve 5 and the second main valve 6. The first main valve 5 and the second main valve 6 can control the flow of materials in the top pipe 4, so that the material flow direction can be switched in time when it is needed, so as to extend the operation cycle of the device.

[0025] Furthermore, the outer wall of the bottom pipe 11 is respectively installed with a third main valve 9 and a fourth main valve 10, and the intersection of the second interconnecting pipe 7 and the bottom pipe 11 is located between the third main valve 9 and the fourth main valve 10. The third main valve 9 and the fourth main valve 10 can control the flow of materials in the bottom pipe 11, so that the material flow direction can respond in time when switching is required.

[0026] Furthermore, a first auxiliary valve 3 is installed at the top of the junction of the first interconnecting pipe 2 and the top pipe 4, and a second auxiliary valve 8 is installed at the bottom of the junction of the second interconnecting pipe 7 and the bottom pipe 11. The bottom end of the first interconnecting pipe 2 is connected with the top end of the bottom pipe 11 near the fourth main valve 10. The first auxiliary valve 3 can control the material in the top pipe 4 to flow into the first interconnecting pipe 2, and the second auxiliary valve 8 can control the material in the bottom pipe 11 to flow into the second interconnecting pipe 7, thereby realizing the switching of the material flow direction.

[0027] Furthermore, the top end of the second interconnecting pipe 7 is connected through the bottom end of the top pipe 4 near the first main valve 5. The second interconnecting pipe 7 can allow the material in the bottom pipe 11 to flow into the top pipe 4, so that the bottom pipe 11 and the top pipe 4 are interconnected, thereby realizing the interconnection of material flow.

[0028] Furthermore, a block 19 is fixedly connected to one end of the cross frame 17, and a bead 18 is fixedly connected to the middle of the vertical rod 13. The surface of the bead 18 is smooth, and a groove is provided on the side wall of the block 19, so that the intersection position of the vertical rod 13 and the cross frame 17 can be maintained at the same position and is not easy to change, thereby increasing the stability of the vertical rod 13 on the cross frame 17.

[0029] Furthermore, the bead 18 is movably embedded in the block 19 , and the vertical rod 13 is movably connected to the horizontal frame 17 through the block 19 and the bead 18 , so that the vertical rod 13 can rotate smoothly on the horizontal frame 17 , thereby realizing the rotation of the stirring rod 16 driven by the vertical rod 13 .

[0030] The method of using this embodiment is as follows: when using the device for improving the redundancy of the service life of the anti-disproportionation fixed bed, it is necessary to first connect the device with other equipment or pipelines, and then the material flow can be introduced into the bottom pipe 11. At this time, the first main valve 5, the second main valve 6, the third main valve 9 and the fourth main valve 10 are in the open mode, and the first auxiliary valve 3 and the second auxiliary valve 8 are in the closed mode. Then, the material flow rushing in from the bottom pipe 11 will pass through the water cap 15 to impact the blade 14 at the bottom end of the vertical rod 13, so that the blade 14 at the bottom end of the vertical rod 13 rotates, driving the vertical rod 13 to rotate in the reactor 1 through the cross frame 17, and driving the stirring rod 16 on the outer wall of the vertical rod 13 to stir in the reaction bed 12, so that the material flow entering the reaction bed 12 and the resin After sufficient contact reaction, the product generated after the reaction will flow out of the reactor 1 through the top pipe 4. When the water cap 15 at the top pipe 4 is damaged, it is necessary to close the first main valve 5 and the fourth main valve 10, keep the second main valve 6 and the third main valve 9 open, and at the same time, open the first sub-valve 3 and the second sub-valve 8, so that the material flow entering from the bottom pipe 11 enters the top pipe 4 through the first interconnecting pipe 2, so that the material flow enters the reactor 1 from the top pipe 4, and the product after the reaction will flow out from the bottom pipe 11, and flow through the top pipe 4 through the second interconnecting pipe 7 and then be discharged from the reactor 1, so that the material flow of the reactor 1 is reversed, so that the resin is not easy to flow with the material to the damaged water cap 15 of the top pipe 4, so as to extend the operation cycle of the reaction device.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
