Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to an internal stepped cyclone collector. Background Technique

[0002] In chemical equipment, a catalyst cyclone collector is used for collecting catalysts in a chemical catalytic fluidized bed reactor. It can not only recover expensive solid fine particle catalysts for recycling in the fluidized bed to reduce economic losses, but more importantly, it can maintain the physical and chemical performance stability of the fluidized bed. In order to have reliable collection efficiency, internal cyclone collectors mostly adopt three-stage series connection (some are two-stage series connection).

[0003] The "stepped cyclone collector in a gaseous catalytic fluidized bed reactor" disclosed in the patent application with the application number "200720036008.9" has a stepped arrangement of the cyclone collectors in the fluidized bed reactor, that is, the outlet of the previous-stage cyclone collector extends to a height greater than or equal to the straight cylinder height of the cyclone collector and then directly corresponds to and is connected to the inlet of the next stage, forming a series connection and a stepped arrangement; the same-stage cyclone collectors in different groups are arranged at the same height or at similar heights. The stepped arrangement of the utility model enables there to be only the same-stage cyclones at the same height in the fluidized bed, thus greatly reducing the installation space, making the installation and design layout simpler. At the same time, the diameter of the fluidized bed does not need to be enlarged at the same height, facilitating equipment manufacturing and reducing investment.

[0004] However, the above method still has the following defects: The method of using a stepped distribution and series connection can reduce the diameter of the fluidized bed to a certain extent, but the captured particles need to be discharged separately through multiple-stage cyclone collectors, making it difficult to centrally discharge the captured particles, and the discharging efficiency is low. Content of the Utility Model

The air inlet end of the first cyclone catcher 401 is fixedly connected to an input pipe 406. The air outlet end of the third cyclone catcher 403 is fixedly connected to an output pipe 407. Through the input pipe 406 and the output pipe 407, the unidirectional flow of gas can be ensured. Through the first conduit 404 and the second conduit 405, the first cyclone catcher 401, the second cyclone catcher 402, and the third cyclone catcher 403 can be connected, and multi-stage recovery of particles in the air flow can be carried out. At the bottom of the first cyclone catcher 401, the bottom of the second cyclone catcher 402, and the bottom of the third cyclone catcher 403, conical hoppers 408 are provided. On the surface of the conical hopper 408, a mounting ring 409 is welded. The bottom end of the mounting ring 409 is fixedly connected to the top end of the ladder plate 3 through screws. On the surface of the ladder plate 3, a placement groove 5 that is snap-connected to the conical hopper 408 is opened. Through the placement groove 5, the conical hopper 408 can be placed to prevent the horizontal displacement of the conical hopper 408, and it can be fixed through the mounting ring 409. A sealing ring 6 is fixedly arranged inside the placement groove 5. Through the sealing ring 6, the space between the mounting ring 409 and the placement groove 5 can be sealed;

[0025] In this embodiment, preferably, the driving component 13 includes a cylinder 1301, a push-pull plate 1302, and a connecting rod 1303. The telescopic rod of the cylinder 1301 is fixedly connected to the push-pull plate 1302. One side of the push-pull plate 1302 is fixedly provided with a connecting rod 1303. The connecting rod 1303 is slidably connected to the bottom of the housing 1. The middle of the baffle 9 is fixedly connected to the connecting rod 1303. One end of the cylinder 1301 is provided with a support 1304. The top of the support 1304 is fixedly connected to the bottom end of the inclined guide plate 11. The cylinder 1301 can be supported by the support 1304. The baffle 9 can be supported by the cylinder 1301 through the push-pull plate 1302 and the connecting rod 1303, so as to maintain the stability of the baffle 9. By driving the baffle 9 with the cylinder 1301, the feeding port 8 can be opened;

[0026] In this embodiment, preferably, an installation opening is formed on the surface of the housing 1. One side of the installation opening is hinged with a sealing door 2. By opening the sealing door 2, the disassembly and assembly of the particle recovery component 4 can be carried out through the installation opening. A discharge valve 14 is fixedly connected to the bottom of one side of the housing 1. By opening the discharge valve 14, the collected particles can be discharged. The bottom end of the inclined guide plate 11 is fixedly connected to a base 15. A maintenance opening is formed in the middle of the base 15. One side of the maintenance opening is hinged with a maintenance door 16. The inclined guide plate 11 can be stably supported by the base 15. By opening the maintenance door 16, it is convenient to repair the vibration motor 12.

[0027] During use, the staff first input gas into the housing 1 through the input pipe 406 of the particle recovery component 4. The gas passes through the first cyclone catcher 401 and reaches the second cyclone catcher 402 and the third cyclone catcher 403 in sequence through the conduit 404 and the conduit 405. Then, the particles in the gas can be recovered at multiple levels by the first cyclone catcher 401, the second cyclone catcher 402, and the third cyclone catcher 403. The particles can fall through the conical hopper 408. During the process of recovering the particles, the baffle 9 can seal the feeding port 8 through the sealing strip 10.

[0028] After the particles are captured and need to be discharged centrally, the staff first open the discharge valve 14, and then push the connecting rod 1303 to move through the cylinder 1301 of the driving component 13. The connecting rod 1303 can push the baffle 9 to move, thus opening the feeding port 8. The recovered particles can be centrally discharged through the feeding port 8. The inclined guide plate 11 can guide the flow, and the particles can be discharged through the discharge valve 14. During this process, the staff vibrate the inclined guide plate 11 through the vibration motor 12. The inclined guide plate 11 can transmit the excitation force to the particles, preventing the particles from clogging and improving the discharge speed of the particles;

[0029] When it is necessary to disassemble the first cyclone catcher 401, the second cyclone catcher 402 and the third cyclone catcher 403, the staff opens the corresponding sealing door 2, then loosens the screws fixing the mounting ring 409, vertically lifts it, and takes out the conical hopper 408 from the placement groove 5, then it can be quickly disassembled, which is convenient for the maintenance of the first cyclone catcher 401, the second cyclone catcher 402 and the third cyclone catcher 403. Through reverse operation, it can be quickly installed.

[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
