Description

Technical Field

[0001] This invention relates to the field of coal chemical equipment technology, specifically to a hydrogenation cracking reaction device for medium and low-rank coal organic matter. Background Technology

[0002] Low- and medium-rank coals occupy an important position in global coal reserves, and their efficient and clean conversion into high-value-added liquid fuels is a crucial issue in the energy sector. Hydrocracking technology is a key pathway to achieve this conversion. This technology induces the breakdown of the large molecular structure of coal and hydrogenation in a high-temperature, high-pressure hydrogen environment, producing oils and chemicals.

[0003] In existing technologies, the hydrocracking reaction of low- and medium-rank coal requires very high temperature control. Heat transfer within the reactor is a critical aspect. Traditional reactors often employ external jacket heating. This method can easily lead to excessively high coal temperatures near the reactor walls, while materials in the central region may receive insufficient heating. Ordinary stirring devices are insufficient to address the settling problem of solid materials. Uneven material mixing limits the reaction conversion rate, making it difficult to guarantee stable quality and yield of the final product.

[0004] Hydrogenation reactions consume a large amount of hydrogen. To reduce costs, unreacted hydrogen must be recycled. However, the composition of the gas after the high-temperature reaction is very complex. It contains not only water vapor but also aerosols of some light oil products. Existing recycling processes mostly use single-stage condensation. This method has limited efficiency in removing impurities. Returning impure hydrogen to the reaction system can affect the stability of subsequent reactions and may even lead to catalyst deactivation.

[0005] The introduction of organic solvents can effectively improve reaction conditions and promote the dissolution and mass transfer of coal organic matter. However, solvent recovery and regeneration are challenges in the process. Reaction products and solvents are miscible, making simple physical separation ineffective. Simultaneously, various byproducts are generated during the reaction, some of which dissolve in the solvent. If the recovered solvent is not of high purity, recycling it will lead to impurity accumulation. This not only interferes with the main reaction but also forces operators to frequently replenish fresh solvent, significantly increasing production costs. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a hydrogenation cracking reaction treatment device for medium and low-rank coal organic matter, which solves the problems of low overall cracking reaction efficiency and high operating costs caused by uneven heating of coal mixture, incomplete recovery of hydrogen and solvent, and low purity in existing technologies.

[0054] Specifically, the cracking reaction mixture in reaction vessel 205 is discharged into discharge pipe 16 through drain plate 2011, and then diverted to filter 4 through connecting pipe 5 27 for filtration. The light product containing cyclohexane solvent is transported to the interior of diversion pipe 2 32 through connecting pipe 2 30. Other filtered substances are discharged into diversion pipe 1 31 through connecting pipe 6 29. The light product in diversion pipe 2 32 is transported to the interior of distillation column 11 through conveying pipe 3 28 by gas transfer pump 3 36. The light product inside is heated by heating seat 35, causing the cyclohexane solvent to vaporize and be transported to the interior of connecting pipe 1 901. The light product without cyclohexane solvent is discharged through oil drain pipe 3 34, and the vaporized cyclohexane enters the interior of condenser 3 902 through connecting pipe 1 901. The cold water in the storage tank 15 is transported to the delivery pipe 37 by the pump 4 39, and then to the condenser 3 902. The water flows through the guide plate 2 904 on the outer wall of the condensate pipe 2 903, thereby condensing the vaporized cyclohexane in the condensate pipe 2 903. The heated water is discharged into the storage tank 15 through the drain pipe 3 38 for storage. The condensed cyclohexane flows into the drain pipe 1 905, and then into the filter tank 3 12. The uncondensed gas is transported back to the interior of the distillation column 11 through the gas guide pipe 907. The cyclohexane entering the filter tank 3 12 is adsorbed by the activated alumina 908 to remove internal impurities. The cyclohexane solvent is then discharged into the solvent tank 1401 for collection through the drain pipe 2 906.

[0055] Working principle: First, medium and low-rank coal is transported into the reaction tank 205 through the feed port on the sealing cover 204. The heating wire 208 is started to heat the coal, and the heat is transferred to the reaction tank 205 through the heat conduction plate 207 to heat the medium and low-rank coal inside the reaction tank 205. Then, the motor 202 is started to drive the rotating rod 203 to rotate, which drives the stirring rod 209 and the auger frame 2010 to rotate and stir the medium and low-rank coal. The auger frame 2010 turns the medium and low-rank coal at the bottom to the top for uniform heating. After the gas pump 1007 is started, the hydrogen in the hydrogen tank 1005 is extracted through the connecting pipe 1006 and transported to the gas pipe 1001 through the gas pump 1007. The hydrogen is discharged into the protective cover 1003 through one end of the gas pipe 1001 and enters the reaction tank 205 through the protective net 1002 to replace the gas in the reaction tank 205.

[0056] The cyclohexane solvent in solvent tank 1401 is extracted through connecting pipe 1402 by pump 1403 and then transported to the inside of delivery pipe 1404 by pump 1403. Inside reaction tank 205, the medium- and low-rank coal is thoroughly mixed with the cyclohexane solvent by stirring rod 209 and auger 2010, and a cracking reaction is carried out in a hydrogen atmosphere. The hydrogen atmosphere effectively improves the reactivity of coal organic matter and reduces the formation of unsaturated products. Hydrogen is continuously supplied through gas pipe 1001. Connecting pipe 701 is opened, allowing unreacted hydrogen to enter filter tank 702 and pass through filter screen 703 to filter particulate impurities. The hydrogen is then transported to condenser tank 704. Simultaneously, pump 40 is activated to pump water from storage tank 15. Cold water is drawn out and transported to water pipe 41, and then transported to the interior of condenser tank 704 and condenser tank 705 respectively. It is guided by water guide plate 708 to flow on the outer wall of condensate pipe 707 for cooling. Unreacted hydrogen gas passes through condensate pipe 707 and enters collection box 709 before entering condenser tank 705. The unreacted hydrogen gas is cooled while flowing in condensate pipe 707. At the same time, the water and gasified oil in the gas are condensed and dripped into collection box 709. The cooled and dehydrated hydrogen gas is discharged into filter tank 8 through exhaust pipe 7011, so that the hydrogen gas flows in grid plate 18 and activated carbon filter element 19. Impurities are adsorbed by activated carbon filter element 19. The impurity-free hydrogen gas is discharged into hydrogen tank 1005 for storage through connecting pipe 4 17.

[0057] After the cold water in condenser tank 1 704 and condenser tank 2 705 cools the condensate pipe 1 707, the water is heated and discharged into the hot water pipe 1408, so that the hot water is delivered to the preheating pipe 6. The hot water is guided by the guide plate 1407 and flows on the outer wall of the delivery pipe 1404 to preheat the cyclohexane solvent in the delivery pipe 1404. The hot water is then discharged into the water storage tank 15 through the drain pipe 1406 at the other end of the preheating pipe 6 for collection.

[0058] The cracking reaction mixture in reaction vessel 205 is discharged into discharge pipe 16 through drain plate 2011, and then diverted to filter 4 through connecting pipe 5 27 for filtration. The light product containing cyclohexane solvent is transported to the interior of diversion pipe 2 32 through connecting pipe 2 30. Other filtered substances are discharged into diversion pipe 1 31 through connecting pipe 6 29. The light product in diversion pipe 2 32 is transported to the interior of distillation column 11 through conveying pipe 3 28 by gas transfer pump 3 36. The light product inside is heated by heating seat 35, causing the cyclohexane solvent to vaporize and be transported to the interior of connecting pipe 1 901. The light product with cyclohexane solvent removed is discharged through oil drain pipe 3 34, and the vaporized cyclohexane enters the interior of condenser 3 902 through connecting pipe 1 901. By starting the transfer pump 439, cold water in the storage tank 15 is transported to the transfer pipe 437, and then to the condenser 3902. The water then flows through the guide plate 2904 on the outer wall of the condensate pipe 2903, thereby condensing the vaporized cyclohexane in the condensate pipe 2903. The heated water is discharged into the storage tank 15 through the drain pipe 338 for storage. The condensed cyclohexane flows into the drain pipe 1905, and then into the filter tank 312. The uncondensed gas is transported back to the interior of the distillation column 11 through the gas guide pipe 907. The cyclohexane entering the filter tank 312 is adsorbed by the activated alumina 908 to remove internal impurities. The cyclohexane solvent is then discharged into the solvent tank 1401 through the drain pipe 2906 for collection.

[0059] The water and oil mixture in the collection box 709 is discharged into the separation box 20 through the oil drain pipe 7010, so that the two baffles 23 block the upper layer of oil. Water flows into one side of the separation box 20 through the opening at the bottom of the partition 24 and the baffle 23. Then, the water is pumped out by starting the second transfer pump 21 and transported to the second transfer pipe 22 and the water storage tank 15. The upper layer of oil is discharged into the oil storage box 26 for collection through the second oil drain pipe 25.
