Description

Technical Field

[0001] This utility model relates to the field of coal tar separation technology, specifically to a stabilizer tower for a coal tar hydrofractionation system. Background Technology

[0002] Stabilizers are common separation equipment in industries such as petrochemicals and coal chemicals. They are mainly used to separate light and heavy components in mixtures to ensure product stability and purity. Stabilizers used in coal tar hydrofractionation systems are generally plate towers with multiple trays. During operation, uneven liquid distribution, improper pressure or reflux ratio control, and other issues often lead to clogging of the sieve trays. This not only reduces separation efficiency but also affects product quality. Existing stabilizers, when severe clogging occurs, generally require opening the tower and having workers use high-pressure water guns or chemical cleaning agents to clean the blockages, a cumbersome process. Therefore, there is an urgent need for a new stabilizer for coal tar hydrofractionation systems. Utility Model Content

[0032] Liquid supply pipe 9 is fixedly installed on the rear side of tower body 1. One end of liquid supply pipe 9 is connected to an external water pump. Several branch pipes 10 are provided on liquid supply pipe 9. One end of branch pipe 10 passes through the side wall of tower body 1 and is rotatably connected to high pressure spray pipe 7 through a sealed bearing. A reinforcing frame 22 is fixedly sleeved on liquid supply pipe 9 and fixedly installed on tower body 1. The reinforcing frame 22 can improve the connection between liquid supply pipe 9 and tower body 1, thereby making the fixation of liquid supply pipe 9 more stable.

[0033] A fixed shell 11 is fixedly installed on the front side of the tower body 1. A rotating rod 12 is fixedly installed at the front end of the high-pressure nozzle 7. The front end of the rotating rod 12 rotates through the side wall of the tower body 1 and is rotatably connected to the inner wall of the fixed shell 11 through a bearing. A gear 13 is fixedly sleeved on the rotating rod 12 and the gear 13 is located inside the fixed shell 11. A synchronous reciprocating drive mechanism 14 that cooperates with several gears 13 is provided inside the fixed shell 11.

[0034] The synchronous reciprocating drive mechanism 14 includes:

[0035] Motor 14-1 is located inside the fixed housing 11. A rotating disk 14-2 is fixedly installed on the output shaft of motor 14-1. A connecting rod 14-3 is rotatably connected to the rear side wall of the rotating disk 14-2 through a rotating shaft.

[0036] The movable frame 14-4 is movably disposed within the fixed shell 11. One end of the connecting rod 14-3 is rotatably connected to the movable frame 14-4 via a rotating shaft. Several slide rails 15 are fixedly disposed on the left and right inner side walls of the fixed shell 11. A slider 16 is slidably disposed on the slide rails 15 and is fixedly connected to the movable frame 14-4. The slider 16 and the slide rails 15 can provide auxiliary guidance for the movement of the movable frame 14-4, thereby improving the stability of the movable frame 14-4 within the fixed shell 11.

[0037] Racks 14-5, several racks 14-5, are fixedly installed on the left and right side walls of the movable frame 14-4, and the racks 14-5 mesh with gears 13. A lifting frame 17 is movably installed inside the fixed housing 11. A first motor 14-1 is fixedly installed on the lifting frame 17. An internal threaded cylinder 18 is fixedly installed at the bottom of the lifting frame 17. A second motor 23 is fixedly installed on the fixed housing 11. A threaded rod 19 is fixedly installed on the output shaft of the second motor 23, and the upper end of the threaded rod 19 is inserted into the internal threaded cylinder 18 through threaded rotation. A sealing plate is fixedly installed inside the connecting frame 6. 20. The sealing plate 20 and the high-pressure nozzle 7 are in movable contact. By rotating the second motor 23 and using the cooperation of the internal threaded cylinder 18 and the threaded rod 19, the height position of the lifting frame 17 and the first motor 14-1 in the fixed shell 11 can be adjusted. In this way, the initial position height of the movable frame 14-4 in the fixed shell 11 can be adjusted. Under the meshing action of the gear 13 and the rack 14-5, the nozzle 8 of the high-pressure nozzle 7 can be rotated to the bottom of the sealing plate 20 to close the nozzle 8, thus preventing gas and liquid from entering the high-pressure nozzle 7 through the nozzle 8 when the stabilizer is in operation.

[0038] When using this invention, motor 23 can be started. Motor 23 drives the threaded rod 19 to rotate, causing the internal threaded cylinder 18 to move the lifting frame 17 downward. The lifting frame 17 drives motor 14-1 to move downward, and under the action of the rotating disk 14-2 and connecting rod 14-3, it drives the movable frame 14-4 to move downward. The movable frame 14-4 drives the rack 14-5 to move downward. By utilizing the meshing of gear 13 and rack 14-5, gear 13 drives rotating rod 12 to rotate. Rotating rod 12 drives high-pressure nozzle 7 to rotate, causing nozzle 8 to flip out from under sealing plate 20. Then, the external water pump delivers water to the high-pressure nozzle 7 through the supply pipe 9 and the diversion pipe 10, and sprays the water onto the tray 2 through the nozzle 8 to clean the blockage on the tray 2. At the same time, the first motor 14-1 can be started. The first motor 14-1 drives the rotating disk 14-2 to rotate, and with the cooperation of the connecting rod 14-3, the movable frame 14-4 moves up and down reciprocally. The movable frame 14-4 drives the rack 14-5 to move up and down reciprocally, so that the gear 13 drives the high-pressure nozzle 7 to rotate back and forth through the rotating rod 12, so that the water sprayed from the nozzle 8 can act on the entire upper surface of the tray 2.

[0039] Compared with the prior art, the beneficial effects of this utility model are:

[0040] 1. Through the cooperation of high-pressure nozzle 7, liquid supply pipe 9, diversion pipe 10, fixed shell 11, rotating rod 12, gear 13 and synchronous reciprocating drive mechanism 14, the upper part of multiple trays 2 can be cleaned simultaneously, thus greatly improving the cleaning efficiency of trays 2.

[0041] 2. Through the cooperation of the lifting frame 17, the internal threaded cylinder 18, the threaded rod 19, the No. 2 motor 23 and the sealing plate 20, the nozzle 8 can be sealed and protected, preventing the phenomenon of gas and liquid entering the high-pressure nozzle 7 through the nozzle 8 when the stabilizer is in operation.

[0042] 3. The connection between the liquid supply pipe 9 and the tower body 1 can be strengthened by the reinforcement frame 22, which makes the fixation of the liquid supply pipe 9 more stable;

[0043] 4. The baffle 21 provides protection above the high-pressure nozzle 7 to prevent liquid flowing out of the downcomer 3 from falling onto the high-pressure nozzle 7.

[0044] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
