Abstract
Description
Technical Field
[0001] This utility model relates to the field of cyclone separator technology, specifically a highly stable ash discharge pipe fixing device. Background Technology
[0002] In the structure of a circulating fluidized bed reactor, a cyclone separator is an indispensable piece of equipment. Its main function is to separate high-temperature solid particles from the exhaust gas, and to discharge the solids from the bottom. As a solid-gas separation device, the cyclone separator works by introducing airflow tangentially, generating rotational motion, which throws solid particles with large inertial centrifugal force against the outer wall for separation, while the gas is discharged from the top of the cyclone separator. In the cold hydrogenation reaction process, silicon powder is used, and solid silicon powder particles are mixed in with the byproducts. Filtering and recovering these solid silicon powder particles requires solid-gas separation within a cyclone separator, followed by collection of the solid silicon powder particles.
[0003] The existing cyclone separators are fixedly welded to the inner wall of the reactor, which is a rigid connection. Under the high-temperature environment of the reaction, both the cyclone separator and the reactor will undergo a certain degree of deformation. Prolonged use may lead to weld failure and other safety hazards, posing a high safety risk. Utility Model Content
[0004] To address the problems of deformation and material backflow caused by the fixed connection of traditional cyclone separators in the above-mentioned technologies, this utility model provides a highly stable ash discharge pipe fixing device.
[0005] The technical solution of this utility model is as follows:
[0006] A highly stable ash discharge pipe fixing device includes a reactor and multiple separators disposed inside the reactor, wherein an ash discharge pipe is disposed at the bottom of the separators;
[0007] The outer surface of the ash discharge pipe is fitted with a fixing ring, and a connecting rod for connecting different fixing rings is provided outside the fixing ring. Multiple support rods are provided circumferentially on the fixing ring, and there is an included angle between adjacent support rods. A buffer ring is provided between the support rod and the reactor, and the side of the buffer ring away from the support rod is in contact with the inner wall of the reactor.
[0008] Furthermore, in the above-described stable ash discharge pipe fixing device, multiple support rods are distributed on the side of the fixing ring away from the connecting rod, and the included angle between adjacent support rods ranges from 30 to 120°.
[0009] Furthermore, in the above-described stable ash discharge pipe fixing device, the number of connecting rods is one or more, and the two ends of each connecting rod are respectively connected to different fixing rings.
[0010] Furthermore, in the above-described stable ash discharge pipe fixing device, the surface of the ash discharge pipe is also provided with fixing pins, and the fixing ring is embedded between adjacent fixing pins.
[0011] Furthermore, in the above-described stable ash discharge pipe fixing device, a sealing ring is provided between the fixing ring and the ash discharge pipe, and the sealing ring is fitted onto the outer surface of the ash discharge pipe.
[0012] Furthermore, in the above-described stable ash discharge pipe fixing device, multiple fixing rings are provided; preferably, the number of fixing rings is set between 2 and 5 sets.
[0013] Furthermore, in the aforementioned stable ash discharge pipe fixing device, the outlet of the separator is connected to the reactor via an upper end cap.
[0014] Furthermore, in the above-mentioned stable ash discharge pipe fixing device, the buffer ring is an arc-shaped opening with a side opening range of 30-90°.
[0015] Furthermore, in the above-mentioned stable ash discharge pipe fixing device, the buffer ring is provided with an open arc shape at one end near the inner wall of the reactor, and the angle of the opening is 10-20°.
[0016] Furthermore, in the above-described stable ash discharge pipe fixing device, the fixing rings are arranged in an even number, and the multiple connecting rods are rotatably connected by pins.
[0017] The beneficial effects of this utility model are as follows:
[0018] This invention features an extended ash discharge pipe installed below the separator. Multiple fixing rings are fitted onto the surface of the ash discharge pipe, with connecting rods linking adjacent fixing rings. A sealing ring is also installed between the fixing rings and the ash discharge pipe to enhance its shock absorption capacity. Additionally, multiple support rods are installed on the side of the fixing rings away from the connecting rods, and a buffer ring is installed on the side of the support rings away from the fixing rings. The buffer ring contacts the inner wall of the reactor, effectively securing the ash discharge pipe. Furthermore, the open-type buffer ring effectively reduces vibrations generated by the ash discharge pipe, preventing vibrations from affecting the reactor. This not only improves the stability and durability of the equipment but also enhances the safety of its operation. Attached Figure Description

[0030] Example 1
[0031] like Figure 1-3 The ash discharge pipe fixing device shown is designed to address the problem of deformation of the cyclone separator 2 caused by the rigid connection between the traditional cyclone separator 2 and reactor 1, which can lead to weld breakage and safety hazards over time. This embodiment includes a reactor 1 and multiple separators 2 disposed inside the reactor 1. Two sets of ash discharge pipes 3 are provided. The outlet of the separator 2 is connected to the reactor 1 via an upper end cap. The ash discharge pipe 3 is vertically installed at the bottom of the separator 2. The ash discharge pipe 3 is a seamless pipe, and the ash discharge pipe 3 in this embodiment is an extended structure compared to the traditional ash discharge pipe 3.
[0032] To better fix the ash discharge pipe 3, a fixing ring 4 is fitted on the outer surface of the ash discharge pipe 3. Multiple sets of fixing rings 4 are provided, and the number of fixing rings 4 in the same horizontal direction is the same as the number of ash discharge pipes 3. In this embodiment, there are two fixing rings 4 in the same horizontal direction. In addition, multiple sets of fixing rings 4 are provided in the vertical direction of the ash discharge pipe 3, with a number of 2-5 sets. Preferably, in this embodiment, there are 2 sets of fixing rings 4 in the vertical direction. In addition, in the horizontal direction, a connecting rod 5 is provided on the surface of the fixing ring 4. The connecting rod 5 is specifically arranged between adjacent fixing rings 4, and both ends of the connecting rod 5 are fixedly connected to the adjacent fixing ring 4. At least one connecting rod 5 is provided. In this embodiment, the number of connecting rods 5 is set to 1.
[0033] Multiple support rods 6 are arranged circumferentially around the fixed ring 4, as shown in the figure. In this embodiment, multiple support rods 6 are arranged on the side away from the connecting rod 5. Preferably, two support rods 6 are arranged in this embodiment. The support rods 6 are fixedly connected to the fixed ring 4. There is a certain included angle between the support rods 6 located on the same surface of the fixed ring 4. The included angle ranges from 30° to 120°. In this embodiment, the included angle between adjacent support rods 6 is 90°. In addition, a buffer ring 7 is arranged on the side of the support rod 6 away from the fixed ring 4. The buffer ring 7 is fixedly connected to the support rod 6. The side of the buffer ring 7 away from the support rod 6 contacts the inner wall of the reactor 1. The buffer ring 7 is an open arc-shaped structure. In this embodiment, the buffer ring 7 is an arc-shaped structure with a side opening. The angle of the side opening ranges from 30° to 90°. In this embodiment, the opening angle is 60°.
[0034] It is worth noting that, in order to prevent the fixing ring 4 from slipping off the surface of the ash discharge pipe 3, fixing pins 8 are also provided on the surface of the ash discharge pipe 3. Pairs of fixing pins 8 are distributed on the upper and lower sides of the fixing ring 4 and contact the upper and lower surfaces of the fixing ring 4. The distance between the fixing pins 8 on the upper and lower sides of the same fixing ring 4 is greater than the thickness of the fixing ring 4, meaning the fixing ring 4 is embedded between the pairs of fixing pins 8. To further enhance the stability of the connection between the fixing ring 4 and the ash discharge pipe 3, a sealing ring 9 is also provided between the fixing ring 4 and the ash discharge pipe 3. The sealing ring 9 is sleeved on the surface of the ash discharge pipe 3 and is made of fluororubber.
[0035] When using this device, firstly, use measuring tools to measure the distance between the extended ash discharge pipes 3 at the bottom of the two cyclone separators 2 and the distance between the ash discharge pipes 3 and the inner wall of the reactor. Based on the measurement results, determine the lengths of the connecting rods 5 and support rods 6, as well as the angle range between adjacent support rods 6, and then assemble them. During installation, first, put the sealing ring 9 on the outer surface of the ash discharge pipe 3, and then put the fixing ring 4 on the outside of the sealing ring 9, so that the lower part of the fixing ring 4 contacts the fixing pin 8. Then, install another fixing pin 8 on the upper surface of the fixing ring 4, so that the fixing ring 4 is fixed between the fixing pins 8, and make the end of the buffer ring 7 away from the support rod 6 contact the inner wall of the reactor 1, thus completing the installation of the fixing device.
[0036] Example 2
[0037] See attached document Figure 1 Appendix Figure 3 and attached Figure 4 The difference from Embodiment 1 lies in the structure and quantity of the support rod 6. The materials, specifications, and connection methods of the remaining components are the same as in Embodiment 1. The specific differences are as follows:
[0038] In this embodiment, each fixed ring 4 is provided with 4 sets of support rods 6 on its outer side. The number of corresponding buffer rings 7 is the same as the number of support rods 6, which is four sets. The included angle between adjacent support rods 6 is set to 60°.
[0039] The structure of the four support rods 6 can more effectively reduce the generation of vibration, provide strong support for the fixed ring 4, and greatly reduce the safety hazards caused by vibration.
[0040] Example 3
[0041] See attached document Figure 1 Appendix Figure 3 and attached Figure 5 The difference from Embodiment 1 is the number and mechanism of the fixing rings 4; all other components are the same as in Embodiment 1. The specific differences are:
[0042] In this embodiment, three sets of fixing rings 4 are arranged in the same horizontal plane, which is suitable for the case where three sets of separators 2 are arranged inside the reactor 1. In this embodiment, the three sets of fixing rings 4 are distributed in a triangular shape, and adjacent fixing rings 4 are fixedly connected by connecting rods 5. On the side of the fixing rings 4 away from the connecting rods 5, there are support rods 6 and buffer rings 7 with the same number and structure as in embodiment 2.
[0043] The structure of three sets of triangularly distributed fixing rings 4 and connecting rods 5 between adjacent fixing rings 4 can achieve synchronous vibration reduction between multiple pipes, and the triangular distribution structure can enhance the stability of the connection.
[0044] Example 4
[0045] See attached document Figure 1 Appendix Figure 3 and attached Figure 6 The difference from Embodiment 1 is the number and structure of the fixing rings 4 and the connecting rods 5. The rest of the components are the same as in Embodiment 1. The specific differences are:
[0046] When the separator 2 is equipped with an even number of ash discharge pipes 3, there are also an even number of corresponding fixing rings 4 in the same horizontal plane, and the connecting rods 5 that cooperate with them are fixed in the middle by a pin. Each connecting shaft can rotate relative to the pin. In this embodiment, there are 4 sets of ash discharge pipes 3 and 2 connecting shafts, and the 2 connecting rods 5 are supported in a cross-shaped structure.
[0047] The cross-shaped rotatable connecting rod 5 set between the four fixed rings 4 can realize synchronous vibration reduction of multiple pipes, enhance the stability of the connection, and greatly improve the vibration reduction effect.
[0048] Example 5
[0049] See attached document Figure 1 Appendix Figure 3 and attached Figure 7 The difference from Embodiment 1 is the structure of the buffer ring 7; all other components are the same as in Embodiment 1. The specific differences are:
[0050] In this embodiment, the buffer ring 7 has an arc-shaped opening structure with the opening facing the inner wall of the reactor 1. The opening angle is 10-20°, and in this embodiment, the opening angle is 18°.
