Description

Technical Field

[0001] This utility model relates to the field of hydrogenation reactors, specifically a double-layer filtration device in a fixed-bed continuous hydrogenation reactor. Background Technology

[0002] In the operation of a fixed-bed continuous hydrogenation reactor, impurities in the feedstock have a significant impact on the activity and selectivity of the catalyst. To ensure the efficient and stable operation of the hydrogenation reaction, the feedstock entering the reactor must undergo strict filtration. Traditional filtration devices often employ a single-layer filtration structure, which has limited filtration efficiency and cannot meet the requirements of high-precision filtration. Furthermore, the disassembly and cleaning of traditional filtration devices are cumbersome and time-consuming, affecting production efficiency and the convenience of equipment maintenance. Therefore, we propose a double-layer filtration device for the fixed-bed continuous hydrogenation reactor. Utility Model Content

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a double-layer filtration device inside a fixed-bed continuous hydrogenation reactor, comprising a hydrogenation reactor base, a hydrogenation reactor shell fixedly installed on the top of the hydrogenation reactor base, a sealing cover for sealing the hydrogenation reactor base slidably installed on the top of the hydrogenation reactor shell, a main rod extending out of the hydrogenation reactor shell fixedly installed on the top of the hydrogenation reactor base corresponding to the inside of the hydrogenation reactor shell, a component sleeve slidably sleeved on the outer wall of the main rod, a filter plate A slidably sleeved on the outer wall of the component sleeve, a filter plate B slidably sleeved on the outer wall of the component sleeve corresponding to the lower part of the filter plate A, and a ring-shaped protective ring fixedly installed on the top of the filter plate B near its edge, and further comprising:

[0005] Quick-release assembly, which is installed on the assembly sleeve, is used for quick disassembly of filter plate A and filter plate B.

[0006] Preferably, the sealing cap is slidably sleeved on the outer wall of the main rod, and half-spherical limiting steel balls are fixed on both sides of the outer wall of the main rod near the bottom position, with the top of the limiting steel balls fitting against the bottom of the component sleeve.

[0008] Preferably, the top of the filter plate A has a plurality of first filter holes extending to the bottom, and the top of the filter plate B has a plurality of second filter holes extending to the bottom.

[0009] Preferably, the quick-release assembly includes a fixing rod, a locking plate, a compression spring, a limiting cover, and an insert rod. The outer walls of both sides of the assembly sleeve are fixedly connected to the filter plate A and the filter plate B. The ends of the two sets of fixing rods that are facing away from each other are fitted with limiting covers. The outer walls of the two sets of fixing rods are slidably fitted with locking plates. The outer walls of the fixing rods are fitted with compression springs between the locking plates and the assembly sleeve. The two sets of locking plates are fixedly connected to a pair of insert rods on the opposite sides of each other. The pair of insert rods are respectively located on the side of the locking plates near the top and bottom.

[0010] Preferably, the quick-release assembly further includes a slot A, a socket A, a slot B, and a socket B.

[0013] Compared with the prior art, this utility model provides a double-layer filtration device in a fixed-bed continuous hydrogenation reactor, which has the following beneficial effects:

[0014] 1. The fixed-bed continuous hydrogenation reactor features a double-layer filtration system with a quick-release assembly. By pulling the locking plate, the compression spring deforms and shortens, allowing the insertion rod to slide out of the insertion hole, thus easily and quickly disassembling filter plate A and filter plate B. This design greatly simplifies the disassembly and cleaning process, improving production efficiency and ease of equipment maintenance.

[0015] 2. The fixed-bed continuous hydrogenation reactor features a dual-layer filtration system. Through its dual-layer filtration structure—filter plate A and filter plate B—it can more effectively remove impurities from the feedstock, meeting the requirements for high-precision filtration. This design significantly improves filtration efficiency, ensuring the efficient and stable operation of the hydrogenation reaction. A ring-shaped protective ring is fixed to the top of filter plate B near its edge, effectively preventing filtered material from sliding off filter plate A onto filter plate B, thus ensuring a clean and efficient filtration process.

[0039] Quick-release assembly (including fixing rod 19, locking plate 20, compression spring 21, limiting cover 22, and insertion rod 23): Installed on the assembly sleeve 5, it is used for quick disassembly and reassembly of filter plate A6 and filter plate B7. The fixing rod 19 is fixedly connected to the outer walls of both sides of the assembly sleeve 5 between filter plate A6 and filter plate B7.

[0041] Working principle: When it is necessary to disassemble filter plate A6 and filter plate B7, first slide the sealing cover 3 upward on the top of the hydrogenation reactor shell 2, so that the sealing cover 3 is separated from the hydrogenation reactor shell 2 by the main rod 4. Then, pull the component sleeve 5 upward on the main rod 4, so that the component sleeve 5 gradually slides out of the hydrogenation reactor shell 2 from the outer wall of the main rod 4. After the component sleeve 5 is disassembled on the main rod 4, the two sets of locking plates 20 are brought closer together on the two sets of fixing rods 19. Pulled by the movement of the positioning plate 20, the two sets of compression springs 21 deform and shorten. The two sets of positioning plates 20 slide between the empty slot A11 and the empty slot B16 respectively. When the four sets of insertion rods 23 slide out of the insertion hole A13 and the insertion hole B18 respectively, the filter plate A6 is slid upward on the component sleeve 5 to remove the filter plate A6, and the filter plate B7 is slid downward on the component sleeve 5 to remove the filter plate B7. The protective ring 14 prevents the filtered material on the filter plate A6 from sliding out on the filter plate B7.
