Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, specifically to a device for gas-solid separation. Background Technology

[0002] In various process industries such as petrochemicals, coal chemicals, metallurgy, and clean coal power generation, the separation of solid particulate matter from gases at high temperatures (350–650℃) and under certain pressures (0.1–4.0 MPa) is crucial to meet requirements for product quality upgrades, efficient energy utilization, and pollution emission control. Especially in recent years, with the control of PM2.5 emissions, the requirements for the purification of flue gas emitted from process industries have become more stringent, leading to a trend towards larger-scale and higher-efficiency gas-solid filtration separation technologies and equipment. This is primarily achieved through a 4PE unit, which consists of a prepolymer, a loop reactor, and a gas-phase reactor connected in series. The catalyst undergoes pre-reaction in the prepolymer reactor before entering the loop reactor to produce low-molecular-weight polymers. The active polymers are then flash-evaporated and sent to the gas-phase reactor for further reaction, yielding the final polymer. After the polymer from the gas-phase reactor is discharged through the discharge system, it undergoes steaming and drying before entering this gas-solid separation unit. This unit separates the lumps, powder, and gas. The gas phase is discharged into the flare system via a pressure control valve, while the powder, after passing through the grid plates, is conveyed to the powder silo via a rotary valve and pneumatic conveying system. The lumps are blocked by the grid plates, and once a certain accumulation is reached, the material level changes determine whether to remove them. The steamed and dried powder then enters this separation bag filter for further separation of the gas and powder phases. The bag filter is equipped with pulse filters to ensure unobstructed flow. The upper part of the bag filter is fixed on the tube sheet. The powder feed line after steaming and drying is connected to the sleeve on the tube sheet. The gap between the two is fixed by a clamp with a seal to ensure that the powder does not leak at the gap. However, because the sleeve uses an O-ring sealing type, the O-ring is prone to aging and deformation under pressure, causing powder to leak into the cavity and then leak into the flare system through the pressure control valve, causing safety hazards. Now, the sleeve is fixed with a non-woven fabric clamp, which solves the powder leakage problem. Therefore, we propose a device for gas-solid separation. Utility Model Content

[0003] This invention provides a device for gas-solid separation, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A device for gas-solid separation includes a main body, within which a feeding pipeline is installed. The feeding pipeline includes a feeding sleeve and a perforated sleeve. The perforated sleeve extends into the feeding sleeve and is inserted into it. A through hole for passage is provided at the top of the main body. Non-woven fabric is wrapped around the outside of the perforated sleeve, located at the connection between the feeding sleeve and the perforated sleeve. One end of the non-woven fabric extends to and wraps around one end of the perforated sleeve, while the other end extends out of the feeding sleeve. A positioning mechanism for limiting the non-woven fabric is installed at the end of the perforated sleeve that extends into the feeding sleeve. An auxiliary device for straightening the non-woven fabric is provided on the outside of the perforated sleeve and the feeding sleeve. A clamping device is installed on the outside of the feeding sleeve and the perforated sleeve, capable of clamping the non-woven fabric extending out of the feeding sleeve.

[0005] Optionally, the positioning mechanism includes a rotating ring, a needle, and a ring plate. One end of the patterned plate sleeve extending into the feeding sleeve has an installation groove. One end of the nonwoven fabric is located in the installation groove, and a ring plate for compressing and limiting the nonwoven fabric is inserted into the installation groove. A needle that can be inserted into the nonwoven fabric and the ring plate is movably connected to the patterned plate sleeve, and a rotating ring that can be rotated to push the needle into the groove is movably fitted on the outside of the patterned plate sleeve.

[0006] Optionally, one end of the needle can extend into the interior of the mounting groove and pass through the non-woven fabric to be inserted into the ring plate, and the other end of the needle is round and can abut against the inner side of the rotating ring.

[0007] Optionally, the inner side of the rotating ring is corrugated, and a positioning groove corresponding to the circular end of the needle is formed at the crest of the inner side of the rotating ring.

[0008] Optionally, a first spring is sleeved on the needle to push the needle against the rotating ring. One end of the first spring is fixed to the tube sleeve of the flower plate, and the other end of the first spring is fixed to the needle.

[0009] Optionally, the auxiliary device includes a movable ring and an internally threaded ring. Multiple straight grooves are opened on the outer side of the tube sheet. The movable ring is movably connected in the straight grooves. The non-woven fabric wraps around the outer side of the movable ring. A locking groove is opened at the end of the movable ring away from the feeding sleeve. The other end of the non-woven fabric is located in the locking groove. An internally threaded ring that can limit the non-woven fabric is threadedly connected in the locking groove. A second spring is fixedly connected in the straight groove.

[0010] Optionally, the clamping device includes clamping rings and a connecting frame. Multiple opposing clamping rings are connected to the connecting frame by axle pins. One pair of clamping rings clamps the outside of the feeding sleeve, and another pair clamps the outside of the non-woven fabric on the tube sheet sleeve, and abuts the non-woven fabric against the moving ring. The clamping rings are connected by bolts.

[0011] This utility model has the following beneficial effects:

[0012] 1. This gas-solid separation device effectively prevents powder leakage by installing non-woven fabric at the connection between the feeding sleeve and the tube sheet sleeve. This avoids the problem of O-rings aging and deforming under pressure, which can cause powder to leak into the cavity and then into the flare system through the pressure control valve. The non-woven fabric also provides better leakage prevention through the clamping device.

[0013] 2. This gas-solid separation device, by replacing the clamping ring with a manhole, allows personnel to enter and, when sealing the casing, eliminates the need to lift the top cover, thus making the casing easier to inspect and maintain. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 7 A device for gas-solid separation includes a main body 1, within which a feed line 2 is installed. The feed line 2 includes a feed sleeve 14 and a perforated plate sleeve 15. The perforated plate sleeve 15 extends into and is inserted into the feed sleeve 14, which is prior art and will not be described in detail here. A through hole 3 for personnel passage is installed at the top of the main body 1, replacing the clamping ring 16 with a manhole, allowing personnel to enter. This eliminates the need to lift the top cover when sealing the sleeve, thus facilitating inspection and maintenance. The outside of the perforated plate sleeve 15 is wrapped with non-woven fabric 6, located at the connection between the feed sleeve 14 and the perforated plate sleeve 15, with one end of the non-woven fabric 6 extending to the perforated plate. One end of the sleeve 15 is wrapped around it, while the other end of the nonwoven fabric 6 extends into the feeding sleeve 14, so that the nonwoven fabric 6 can relatively completely wrap the feeding pipeline 2 to ensure the sealing effect between the main body 1 and the feeding pipeline 2. The end of the tube sleeve 15 that extends into the feeding sleeve 14 is equipped with a positioning mechanism to limit the nonwoven fabric 6, and the tube sleeve 15 is provided with an auxiliary device that can straighten the nonwoven fabric 6 outside the feeding sleeve 14. The feeding sleeve 14 and the tube sleeve 15 are equipped with a clamping device, which can clamp the nonwoven fabric 6 extending out of the feeding sleeve 14, so that the nonwoven fabric 6 can be installed in a taut state, thus making the installation of the nonwoven fabric 6 more convenient.

[0024] Please see Figures 1 to 6 The positioning mechanism includes a rotating ring 4, a needle 7, and a ring plate 10. One end of the patterned tube 15 extending into the feeding tube 14 has an installation groove 9. One end of the nonwoven fabric 6 is located in the installation groove 9, and the ring plate 10, which compresses and restricts the nonwoven fabric 6, is inserted into the installation groove 9. Under the restriction of the ring plate 10, the end of the nonwoven fabric 6 can be fixed. The needle 7, which can be inserted into the nonwoven fabric 6 and the ring plate 10, is movably connected to the patterned tube 15. Under the insertion of the needle 7, the nonwoven fabric 6 and the ring plate 10 can be fixed, thereby making the fixing effect of the nonwoven fabric 6 better. The rotating ring 4, which can be rotated to push the needle 7 to insert, is movably fitted on the outside of the patterned tube 15. The rotating ring 4 can rotate in a fixed position on the patterned tube 15.

[0025] Please see Figures 1 to 6One end of the needle 7 can be inserted into the interior of the mounting groove 9 and pass through the non-woven fabric 6 to be inserted into the ring plate 10. The other end of the needle 7 is round and can abut against the inner side of the rotating ring 4, so that the rotating ring 4 can smoothly push the needle 7 to move.

[0026] Please see Figures 1 to 6 The inner side of the rotating ring 4 is corrugated, and a positioning groove corresponding to the circular end of the needle 7 is provided at the crest of the inner side of the rotating ring 4. This allows the rotation of the rotating ring 4 to drive the needle 7 to move, and under the action of the positioning groove, the needle 7 can be stably inserted.

[0027] Please see Figures 1 to 6 A first spring 8 is sleeved on the needle 7, which can push the needle 7 to abut against the rotating ring 4. One end of the first spring 8 is fixed to the flower plate sleeve 15, and the other end of the first spring 8 is fixed to the needle 7. Under the action of the elastic force of the first spring 8, the needle 7 can always be in contact with the rotating ring 4, thereby enabling the rotating ring 4 to smoothly drive the needle 7 to move.

[0028] Please see Figures 1 to 7 The auxiliary device includes a movable ring 12 and an internal threaded ring 13. Multiple straight grooves are opened on the outer side of the tube sleeve 15. The movable ring 12 is movably connected in the straight grooves. The movable ring 12 can move along a fixed trajectory in the straight grooves. The non-woven fabric 6 wraps the outer side of the movable ring 12. A locking groove is opened at the end of the movable ring 12 away from the feeding sleeve 14. The other end of the non-woven fabric 6 is in the locking groove. An internal threaded ring 13 is threadedly connected in the locking groove to limit the non-woven fabric 6. The installation of the internal threaded ring 13 can fix the other end of the non-woven fabric 6. A second spring 11 is fixedly connected in its straight groove. One end of the second spring 11 is fixed to the movable ring 12. Under the action of the elastic force of the second spring 11, the non-woven fabric 6 with both ends fixed can be straightened smoothly.

[0029] Please see Figures 1 to 7 The clamping device includes clamping rings 16 and connecting frame 5. Multiple opposing clamping rings 16 are connected to the connecting frame 5 by shaft pins. One pair of clamping rings 16 clamps the outside of the feed sleeve 14, and another pair clamps the outside of the non-woven fabric 6 on the tube sheet sleeve 15, and abuts the non-woven fabric 6 against the moving ring 12. The clamping rings 16 are connected by bolts, so that the clamping rings 16 can flatten the non-woven fabric 6 and make the fixation between the main body 1 and the feed pipeline 2 more stable.

[0030] In summary, in use, the device for gas-solid separation involves inserting one end of the nonwoven fabric 6 into the mounting groove 9, followed by inserting the ring plate 10 to clamp the nonwoven fabric 6. Then, rotating the rotating ring 4 pushes the needle 7 to move, allowing the needle 7 to extend into the mounting groove 9 and engage with the nonwoven fabric 6 and the ring plate 10. Furthermore, under the elastic force of the first spring 8, the needle 7 extends into the positioning groove. Finally, the nonwoven fabric 6 is flipped over. Wrap the outer side of the tube sheet sleeve 15 and insert the other end of the nonwoven fabric 6 into the locking groove on the moving ring 12. Then, screw the inner threaded ring 13 to restrict the nonwoven fabric 6. At this time, under the push of the second spring 11, the moving ring 12 can straighten the nonwoven fabric 6. Then, insert the tube sheet sleeve 15 into the inside of the feeding sleeve 14 for connection. Then, install the clamping ring 16, which can clamp the nonwoven fabric 6, thereby making its installation more stable.
