Description

Technical Field

[0001] The present invention relates to the technical field of upgrading devices, and particularly relates to a warm solution upgrading device for medium and low rank coal organic matter transformation. Background Art

[0002] Medium and low rank coal accounts for a relatively large proportion in China's coal reserves. It has characteristics such as high moisture content, high ash content, high volatile content, low fixed carbon content, and low calorific value. Direct combustion not only has low thermal efficiency but also causes environmental pollution. To improve the utilization value of medium and low rank coal, it is necessary to carry out upgrading processing on it.

[0003] Therefore, we will put medium and low rank coal into one or more of a hot melt reaction tank, an alcoholysis reaction tank, and a catalytic hydrocracking reaction tank for upgrading operations.

[0004] However, after the upgrading operation, part of the medium and low rank coal dissolves in the corresponding solution, while the other part does not dissolve in the solution. Therefore, we need to remove the remaining medium and low rank coal. The general method for upgrading medium and low rank coal is to pour medium and low rank coal into the solution for reaction, and then use a relatively complex method to take out and collect the undissolved medium and low rank coal or perform another upgrading in another upgrading solution at different temperatures.

[0005] The above method is rather troublesome. Therefore, we design a warm solution upgrading device for medium and low rank coal organic matter transformation, which can first make the medium and low rank coal placement filter frame receive medium and low rank coal at a good angle, then shake the medium and low rank coal evenly, put the medium and low rank coal at this time into the corresponding upgrading solution for efficient upgrading, and then collect the remaining medium and low rank coal after upgrading with high quality, thereby improving the operation efficiency. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects existing in the prior art. The present invention proposes a warm solution upgrading device for medium and low rank coal organic matter transformation, which can first make the medium and low rank coal placement filter frame receive medium and low rank coal at a good angle, then shake the medium and low rank coal evenly, put the medium and low rank coal at this time into the corresponding upgrading solution for efficient upgrading, and then collect the remaining medium and low rank coal after upgrading with high quality.

Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0045] Example 1:

[0046] A device for thermally dissolving and upgrading organic matter in medium and low rank coal mainly includes a first limit sliding plate 7, a mounting plate 1, a first side plate 2, a hot-melt reaction tank 8, an alcoholysis reaction tank 9, and a catalytic hydrocracking reaction tank 10.

[0047] Focus on referring to Figure 1 , Figure 2 and Figure 3 , at the parts near the top of the two first side plates 2, a mounting plate 1 is fixedly connected in common. A first limit chute 6 is provided on the mounting plate 1, and a first limit sliding plate 7 is connected to the first limit sliding plate 7 with left and right limit sliding.

[0048] Focus on referring toFigure 4 On the first limit sliding plate 7, two second side plates 19 are fixedly connected. Between the two second side plates 19, a reverse threaded rod 27 and a forward threaded rod 21 are rotationally connected in a limited manner. The thread pitches of the reverse threaded rod 27 and the forward threaded rod 21 are equal and the directions are opposite, so that when the reverse threaded rod 27 and the forward threaded rod 21 rotate in the reverse direction, they can synchronously drive the object to move up and down.

[0049] Key reference Figure 4 On the outer wall of the reverse threaded rod 27, a third limit sliding plate 28 is threadedly connected. The third limit sliding plate 28 is slidably connected up and down to the first limit sliding plate 7. At the bottom of the third limit sliding plate 28, a second sliding strip 29 is fixedly installed. The second sliding strip 29 is slidably connected up and down to the second side plate 19 at the bottom.

[0050] Key reference Figure 4 On the outer wall of the forward threaded rod 21, a second limit sliding plate 23 is threadedly connected. The second limit sliding plate 23 is slidably connected up and down to the first limit sliding plate 7. At the bottom of the second limit sliding plate 23, a first sliding strip 24 is fixedly connected. The first sliding strip 24 is slidably connected up and down to the second side plate 19 at the bottom. At the bottom of the first sliding strip 24, a slide rail plate 30 is fixedly connected. The slide rail plate 30 is slidably connected left and right to a sliding block 32 through a second limit sliding groove 31 thereon.

[0051] Key reference Figure 5 Between the bottom of the second sliding strip 29 and the sliding block 32, a hinge rod 38 is hinged.

[0052] Key reference Figure 4 At the bottom of the sliding block 32, at least two connecting strips 33 are fixedly connected. At the bottom of the two connecting strips 33, a rack 35 is fixedly connected.

[0053] Key reference Figure 4 At the bottom of the slide rail plate 30, a fixing plate 34 is fixedly connected. At a position near the bottom of the fixing plate 34, a second rotating column 36 is rotationally connected in a limited manner. One end of the second rotating column 36 is fixedly connected to the middle part of the outer wall of one side of the medium and low rank coal placement filter frame 16. The other end of the second rotating column 36 is fixedly connected to a fourth gear 37. The fourth gear 37 meshes with the rack 35, and the rack 35 is placed at the bottom of the fourth gear 37.

[0054] It should be noted that the medium and low rank coal placement filter frame 16 is in the shape of a frame, and the material of the frame is a frame that will not be affected by the reaction. The four sides and the bottom of the outer wall are all filter meshes, which are ultra-fine filter meshes and will not allow the medium and low rank coal to leak out from the filter holes. However, the solution can move back and forth through the filter mesh, so that the quality-improving solution can remain in the hot dissolution reaction tank 8, the alcoholysis reaction tank 9, and the catalytic hydrocracking reaction tank 10.

[0055] Key referenceFigure 4 and Figure 7 On the outer wall of the reverse threaded rod 27, a second gear 25 and a third gear 26 are fixedly connected, and on the outer wall of the forward threaded rod 21, a first gear 22 is fixedly connected.

[0056] For key reference Figure 7 On the first limit sliding plate 7, a second bearing plate 48 is fixedly connected. Between the second bearing plate 48 and the second side plate 19 at the top, a spline shaft 43 is rotationally connected with limited position. On the outer wall of the spline shaft 43, a spline shaft sleeve 44 is slidably connected with limited position up and down. On the outer wall of the spline shaft sleeve 44, a fifth gear 45 is fixedly connected.

[0057] The power output end of the third motor 20 is connected to the spline shaft 43. The third motor 20 is installed on the top of the second side plate 19.

[0058] On the first limit sliding plate 7, a fixed block 49 is fixedly connected. On the top of the fixed block 49, an electric telescopic rod 47 is fixedly connected. On the outer wall of the spline shaft sleeve 44, a first bearing plate 46 is rotationally connected with limited position. The first bearing plate 46 is slidably connected with limited position up and down on the first limit sliding plate 7. The telescopic end of the electric telescopic rod 47 is connected to the first bearing plate 46, so that the fifth gear 45 can be synchronously meshed with the third gear 26 and the first gear 22, or the fifth gear 45 can be separately meshed with the second gear 25. The third gear 26 and the first gear 22 are placed on both sides of the fifth gear 45, so that the reverse threaded rod 27 and the forward threaded rod 21 rotate synchronously in the reverse direction or the reverse threaded rod 27 rotates circumferentially alone, for stably moving the medium and low rank coal placement filter frame 16 up and down to a preset height or for tilting or dumping the medium and low rank coal placement filter frame 16 left and right.

[0059] The device is horizontally and sequentially distributed with a hot melt reaction tank 8, an alcoholysis reaction tank 9, and a catalytic hydrocracking reaction tank 10. The line formed by the hot melt reaction tank 8, the alcoholysis reaction tank 9, and the catalytic hydrocracking reaction tank 10 is parallel to the mounting plate 1. And the hot melt reaction tank 8, the alcoholysis reaction tank 9, and the catalytic hydrocracking reaction tank 10 are placed at the bottom of the mounting plate 1.

[0060] On the outer walls near the top of the hot melt reaction tank 8, the alcoholysis reaction tank 9, and the catalytic hydrocracking reaction tank 10, second pipes 13 and third pipes 39 are respectively installed and communicated. On the outer walls near the bottom of the hot melt reaction tank 8, the alcoholysis reaction tank 9, and the catalytic hydrocracking reaction tank 10, first pipes 12 are respectively installed. Electric valves 11 are installed on the second pipes 13, the third pipes 39, and the first pipes 12.

[0061] Heating elements and temperature detectors are arranged in the hot melt reaction tank 8, the alcoholysis reaction tank 9, and the catalytic hydrocracking reaction tank 10. They are electrically connected to the heater and the temperature detector through a controller, so that the required temperature is maintained in the hot melt reaction tank 8, the alcoholysis reaction tank 9, and the catalytic hydrocracking reaction tank 10.

[0062] A sealing cover plate 15 is fixedly connected to the second sliding bar 29, and the sealing cover plate 15 remains horizontal. The sealing cover plate 15 is placed between the hinge rod 38 and the bottom second side plate 19. The first sliding bar 24 is connected in a vertically limited sliding manner in the limiting notch of the second gear 25, and a sealing member is arranged in the limiting notch so that the limiting notch will not leak air.

[0063] The sealing member can be sealing rubber, that is, sealing rubber is fixedly installed on the inner wall of the limiting notch, so that when the air pressure in the hot melting reaction tank 8, the alcoholysis reaction tank 9, and the catalytic hydrogenation cracking reaction tank 10 is relatively large or small, the sealing rubber will be sucked, so that the sealing rubber blocks the limiting notch. This technology is the prior art. For example, when the limiting notch sucks air, a relatively large amount of rubber at the top can block the limiting notch. When the limiting notch exhales air, a relatively large amount of rubber at the bottom is blown to the inner limiting notch to seal it. The above is only one common implementation manner and is the prior art and will not be elaborated further.

[0064] That is, the downward sealing cover plate 15 can seal the tops of the hot melting reaction tank 8, the alcoholysis reaction tank 9, and the catalytic hydrogenation cracking reaction tank 10.

[0065] By introducing reaction ambient gas through the second pipeline 13, the third pipeline 39 discharges the residual gas, and makes the hot melting reaction tank 8, the alcoholysis reaction tank 9, and the catalytic hydrogenation cracking reaction tank 10 reach the reaction air pressure. The reaction solution is put in through the first pipeline 12 and heated to the required temperature by the heating element. Thus, the hot melting, alcoholysis, and catalytic hydrogenation cracking reactions can be realized.

[0066] The medium and low rank coal placement filter frame 16 can be kept at multiple levels in a horizontal descending manner and can perform left - right tilting or dumping operations at multiple levels. When the medium and low rank coal placement filter frame 16 is above the hot melting reaction tank 8, the alcoholysis reaction tank 9, and the catalytic hydrogenation cracking reaction tank 10, it tilts to receive the external medium and low rank coal, and performs left - right tilting actions to evenly place the medium and low rank coal in the medium and low rank coal placement filter frame 16. When the medium and low rank coal placement filter frame 16 enters the hot melting reaction tank 8, the alcoholysis reaction tank 9, and the catalytic hydrogenation cracking reaction tank 10 for quality improvement, it can perform left - right tilting actions to accelerate the solution mixing. After the quality improvement of the medium and low rank coal placement filter frame 16 is completed, the medium and low rank coal placement filter frame 16 is placed at a low level to dump the remaining medium and low rank coal, and the medium and low rank coal placement filter frame 16 can be placed at multiple levels to dump the remaining medium and low rank coal, so that when dumping the medium and low rank coal multiple times, it can be stably dumped out.

[0067] Embodiment 2: On the basis of Embodiment 1, a technical means is added that can make the medium and low rank coal placement filter frame 16 automatically move left - right to multiple positions.

[0068] Focus on reference Figure 1 and Figure 2, on both sides of the mounting plate 1, there are first rotating columns 5 rotatably connected with limited positions. On the outer walls of the two first rotating columns 5, chain gears 4 are fixedly installed. A cooperating chain 3 is sleeved on the two chain gears 4. A first limit sliding plate 7 is fixedly installed on the chain 3. The first limit sliding plate 7 is slidably connected with limited positions left and right in a first limit sliding groove 6 on the mounting plate 1. The power output end of the first motor 14 is connected to the first rotating column 5 for driving the first limit sliding plate 7 to move left and right.

[0069] Other structures are the same as those in the first embodiment.

[0070] Embodiment 3: On the basis of Embodiment 2, technical means are added to rapidly upgrade the medium and low rank coal placed in the hot dissolution reaction tank 8, alcoholysis reaction tank 9, and catalytic hydrocracking reaction tank 10.

[0071] For key reference Figure 2 and Figure 6 , a plurality of support plates 18 are fixedly installed at the bottoms of the hot dissolution reaction tank 8, alcoholysis reaction tank 9, and catalytic hydrocracking reaction tank 10. A second motor 17 is fixedly installed at the bottoms of the hot dissolution reaction tank 8, alcoholysis reaction tank 9, and catalytic hydrocracking reaction tank 10. The inner bottoms of the hot dissolution reaction tank 8, alcoholysis reaction tank 9, and catalytic hydrocracking reaction tank 10 are rotatably connected with limited positions to a third rotating column 42. On both sides of the top of the third rotating column 42, cross bars 40 are fixedly connected. Stirring rods 41 are fixedly installed on the tops of the cross bars 40. The power output end of the second motor 17 is connected to the third rotating column 42.

[0072] Other structures are the same as those in the second embodiment.

[0073] In this embodiment, in the initial state, the medium and low rank coal placement filter frame 16 is placed above the hot melt reaction tank 8, the alcoholysis reaction tank 9, and the catalytic hydrocracking reaction tank 10. At this time, the electric telescopic rod 47 is started to make the spline shaft sleeve 44 and the fifth gear 45 move upward. The fifth gear 45 meshes with the second gear 25. The third motor 20 is started to make the spline shaft 43, the spline shaft sleeve 44, the third rotating column 42, and the second gear 25 rotate. At this time, the reverse threaded rod 27 is driven to move up and down alone. Under the action of the hinge rod 38, the slider 32, the connecting strip 33, and the rack 35 move left and right. The rack 35 meshes with the fourth gear 37 to drive the medium and low rank coal placement filter frame 16 to tilt, so that the medium and low rank coal placement filter frame 16 is convenient for receiving the crushed medium and low rank coal conveyed from the outside. Or, in order to better receive the medium and low rank coal conveyed from the outside, at this time, the electric telescopic rod 47 is started to make the fifth gear 45 mesh with the third gear 26 and the first gear 22 at the same time. At this time, the reverse threaded rod 27 and the forward threaded rod 21 rotate in the reverse direction. The second slide bar 29 and the first slide bar 24 move up and down synchronously, so that the medium and low rank coal placement filter frame 16 can move smoothly up and down to the required position. After reaching the required position, the electric telescopic rod 47 is started again to make the spline shaft sleeve 44 and the fifth gear 45 move upward. The fifth gear 45 meshes with the second gear 25, so that the medium and low rank coal placement filter frame 16 tilts, so that the medium and low rank coal placement filter frame 16 is convenient for receiving the crushed medium and low rank coal conveyed from the outside. After receiving the medium and low rank coal, at this time, the fifth gear 45 meshes with the second gear 25, so that the medium and low rank coal placement filter frame 16 swings left and right to level the medium and low rank coal.

[0074] A preset amount of solutions such as 1-methylnaphthalene and tetrahydronaphthalene and corresponding co-solvents are added to the hot melt reaction tank 8, a preset amount of absolute ethanol and corresponding solvents for auxiliary reactions are added to the alcoholysis reaction tank 9, and a preset amount of tetrahydronaphthalene solution and corresponding catalysts are added to the catalytic hydrocracking reaction tank 10.

[0075] At this time, start the first motor 14 to move the medium and low rank coal placement filter frame 16 directly above the hot melting reaction tank 8. Start the electric telescopic rod 47 so that the fifth gear 45 meshes with the third gear 26 and the first gear 22 simultaneously. At this time, the medium and low rank coal placement filter frame 16 moves vertically downward. When the medium and low rank coal placement filter frame 16 reaches the solution in the hot melting reaction tank 8, start the electric telescopic rod 47 so that the fifth gear 45 meshes with the second gear 25 alone, causing the medium and low rank coal placement filter frame 16 to tilt left and right. And at this time, start the second motor 17, and cooperate with the stirring of the stirring rod 41 so that the medium and low rank coal in the medium and low rank coal placement filter frame 16 can come into good contact with the solution. Note that the top of the medium and low rank coal placement filter frame 16 is always placed above the solution to prevent the medium and low rank coal from being directly washed into the solution by the solution. Then continue to move the medium and low rank coal placement filter frame 16 downward. At this time, the sealing cover plate 15 seals the top of the hot melting reaction tank 8. The heating element in the hot melting reaction tank 8 heats to a temperature of 600 degrees. Inject reaction ambient gas into the electric valve 11. So that the hot melting reaction tank 8 can carry out a hot melting reaction at this time. At this time, also start the second motor 17 to make the stirring rod 41 stir to accelerate the hot melting reaction.

[0076] After the hot melting is completed, start the third motor 20 to lift the medium and low rank coal placement filter frame 16, and swing the medium and low rank coal placement filter frame 16 left and right to shake the solution inside it. Then use an external drying mechanism to dry the medium and low rank coal at this time, and then transfer it to the alcoholysis reaction tank 9 for alcoholysis, so that the alcoholysis reaction tank 9 maintains a temperature of 300 degrees on the slide rail plate for alcoholysis. After the alcoholysis is completed, it is dried and then transferred to the catalytic hydrocracking reaction tank 10, so that the catalytic hydrocracking reaction tank 10 maintains a temperature of 30 degrees on the 4 slide rail plates for catalytic hydrocracking reaction.

[0077] After drying the catalytic hydrocracking reaction, lower the medium and low rank coal placement filter frame 16 to the waste collection area at this time. At this time, make the second gear 25 rotate circumferentially alone, causing the medium and low rank coal placement filter frame 16 to perform a dumping operation. Note that when the medium and low rank coal placement filter frame 16 performs a dumping operation at this time, it is close to the ground in the waste collection area, so that the medium and low rank coal will not be scattered over a wide area due to dumping. During continuous automatic operation, during the next dumping operation, the medium and low rank coal placement filter frame 16 is at a higher position than the previous time, thus simulating the dumping operation of a person, so that the residual medium and low rank coal after dumping still stably falls on the medium and low rank coal dumped last time, thus enabling better dumping and collection of the residual medium and low rank coal operation.

[0078] The technical scope of the present invention is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
