Description

Technical Field

[0001] This utility model relates to the field of chemical product processing technology, and in particular to a combined treatment device for multi-stage distillation and impurity adsorption of chemical products. Background Technology

[0002] In the production of chemical products, the combined multi-stage distillation and impurity adsorption process is widely used in petrochemical, fine chemical, and pharmaceutical fields due to its high efficiency in separation and purification. Multi-stage distillation utilizes the difference in boiling points of components in a mixture to achieve separation through multiple gas-liquid exchanges; impurity adsorption further improves product purity by selectively adsorbing specific impurities using adsorbent materials. However, existing combined multi-stage distillation and impurity adsorption devices for chemical products cannot quickly remove and replace adsorbent layers when they lose their adsorption capacity, reducing maintenance convenience; furthermore, accidental opening of inspection doors can lead to operator injury or material leakage causing safety accidents, resulting in low safety; and the inability to flexibly adjust the number of distillation units according to actual needs reduces applicability and distillation efficiency.

The front end of the adsorption column 3 is hinged with an inspection door 9, and a locking component for improving safety is connected to the outside of the inspection door 9. A detachable adsorption component for improving maintenance convenience is connected inside the adsorption column 3.

[0031] The detachable adsorption assembly includes a mounting plate 5, which has multiple sets. The outer sides of the multiple sets of mounting plates 5 are all fixedly connected to the inner side of the adsorption tower 3. The interior of the multiple sets of mounting plates 5 is provided with an installation groove 6. An installation block 7 is slidably connected inside the installation groove 6. An adsorption layer 8 is fixedly connected to the inner side of the installation block 7.

[0032] The locking assembly includes a fixing block 10 and a slider 12. One end of the fixing block 10 is fixedly connected to the outside of the adsorption tower 3. A groove 11 is provided on the outside of the adsorption tower 3. One end of the slider 12 slides inside the groove 11, ensuring the movement path of the slider 12. Both the fixing block 10 and the slider 12 have through grooves 13 inside. A locking rod 14 is slidably connected inside the through groove 13. A spring 15 is fixedly connected between the fixing block 10 and the slider 12. The locking rod 14 slides inside the spring 15, which is used to drive the locking rod 14 to move. One end of the locking rod 14 passes through the fixing block 10 and is fixedly connected to the pull plate 16. The locking assembly also includes a locking block 17, one end of which is fixedly connected to one side of the inspection door 9. The locking block 17 has a locking groove 18 inside, and the other end of the locking rod 14 away from the pull plate 16 slides inside the locking groove 18 to fix the locking block 17. The multi-stage distillation column 2 includes multiple distillation units 19, and flanges 20 are fixedly connected at the connection points of the multiple distillation units 19. The flanges 20 have mounting holes 21 inside, and the mounting holes 21 slide inside. A screw 22 is connected, and a nut 23 is threaded onto the outside of the screw 22 for easy installation and disassembly of the distillation unit 19. A first pipe 24 is fixedly connected to one side of the raw material tank 1. One end of the first pipe 24 is connected to the feed inlet of the multi-stage distillation column 2. A first valve 25 is connected to the outside of the first pipe 24. A second pipe 26 is fixedly connected to the top of the multi-stage distillation column 2. One end of the second pipe 26 is fixedly connected to the top of the adsorption column 3. A condenser 27 is connected inside the second pipe 26 to condense high-temperature steam into liquid, which facilitates the adsorption treatment of impurities in the liquid by the subsequent adsorption column 3. A third pipe 28 is fixedly connected to the outlet of the adsorption column 3. One end of the third pipe 28 is fixedly connected to one side of the collection tank 4. A second valve 29 is connected to the outside of the third pipe 28. A discharge pipe 30 is fixedly connected to the other side of the collection tank 4 away from the third pipe 28. The first pipe 24, the second pipe 26 and the third pipe 28 are all insulated pipes to reduce heat loss and ensure the stability of chemical products during transportation.

[0033] Working Principle: When this combined processing unit is in operation, the chemical raw materials in the raw material tank 1 are transported to the multi-stage distillation column 2 via the first pipeline 24 under the control of the first valve 25. Utilizing a detachable connection structure consisting of multiple distillation units 19 connected by flanges 20, screws 22, and nuts 23, the number of distillation stages can be flexibly adjusted. After multi-stage distillation separation within the multi-stage distillation column 2, the high-temperature vapor generated at the top of the column enters the condenser 27 via the second pipeline 26, is condensed into liquid, and then flows into the adsorption column 3. In the adsorption column 3, the detachable adsorption components function; the mounting block 7, carrying the adsorption layer 8, slides along the mounting groove 6 of the mounting plate 5, thus... It allows for quick assembly and disassembly, and efficiently adsorbs and purifies impurities in liquid chemical products. The purified product enters the collection tank 4 for temporary storage through the third pipe 28 and under the control of the second valve 29, and is finally discharged through the discharge pipe 30. During the process, if it is necessary to inspect the adsorption layer 8 in the adsorption tower 3, it can be operated through the locking assembly on the outside of the inspection door 9: pull the pull plate 16 upward, and drive the locking rod 14 to overcome the elastic force of the spring 15 and pull it out of the locking groove 18 of the locking block 17, thus opening the inspection door 9. After maintenance is completed, close the inspection door 9, release the pull plate 16, and the spring 15 pushes the locking rod 14 to re-insert into the locking groove 18 to lock, ensuring the safe operation of the device.
