[0023] To facilitate understanding of the present invention by those skilled in the art, specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood through the specific circumstances.

[0025] like Figure 1 As shown, the present invention provides a driving device, including a rotating shaft 1 and a rotating shaft motor 2 for driving the rotating shaft 1 to rotate. A gear ring 4 is welded to the outside of the rotating shaft 1. A transmission gear 5 is keyed to the motor shaft of the rotating shaft motor 2. The transmission gear 5 and the gear ring 4 are connected by a chain 6. The rotating shaft 1 is driven to rotate by the rotating shaft motor 2. The rotating shaft 1 is a single-sided tubular hollow structure. The rotating side is connected to a water supply drive structure through a first rotary joint 7. The water supply drive structure is used to transport water to the rotating shaft 1. Spray pipes 3 are provided on the side of the rotating shaft 1. There are several groups of four spray pipes 3. The spray pipes 3 are welded and fixed to the side of the rotating shaft 1. The spray pipes 3 are connected to the inside of the rotating shaft 1. A nozzle 8 is provided on the other side of the spray pipe 3. The water transported to the rotating shaft 1 is sprayed out from the nozzle 8 through the spray pipe 3 and sprayed onto the coke powder inside the activation furnace 35.

[0026] After the rotating shaft motor 2 starts, the transmission gear 5 on its motor shaft meshes with the gear ring 4 through the coupling transmission, and transmits the power to the gear ring 4 welded to the outside of the rotating shaft 1, thereby driving the rotating shaft 1 to rotate around its own axis; the water supply drive structure delivers water to the inside of the rotating shaft 1; the water entering the rotating shaft 1 is guided by the spray pipe 3 welded and fixed on the side, and finally sprayed out from the nozzle 8, and is vaporized at high temperature inside the activation furnace, and used for the activation of coke powder inside the activation furnace 35.

[0027] like Figure 2 As shown, the water supply drive structure is used to deliver water to the rotating shaft 1. A first embodiment of the water supply drive structure includes an electromagnetic drive assembly and a water supply assembly, with the electromagnetic drive assembly connected to the water supply assembly via a water supply pipe 34. Figure 3As shown, the electromagnetic drive assembly includes an inner tube 9 and an outer tube 10 located outside the inner tube 9. The inner tube 9 is a pipe structure with internal threads on both sides. One side of the inner tube 9 is connected to the first rotary joint 7, and the other side of the inner tube 9 is threaded to the water supply pipe (34). A unidirectional guide component is slidably fitted in the middle of the inner tube 9. Limiting rings 11 are provided on both sides of the unidirectional guide component. The limiting rings 11 are bonded and fixed to the inner wall of the inner tube 9. The limiting rings 11 are used to limit the unidirectional guide component. An electromagnetic coil 12 is provided in the gap between the inner tube 9 and the outer tube 10. When the electromagnetic coil 12 is connected to a positive and negative direct current that changes alternately at a certain time interval, due to the magnetic field of the electromagnetic coil 12, an alternating thrust is applied to the unidirectional guide component, causing the unidirectional guide component to swing back and forth along the inner tube 9. The amount of water sprayed from the nozzle 8 is adjusted by the back and forth swing of the unidirectional guide component. Figure 4 As shown, the unidirectional guiding component includes a swing ring 13, the diameter of which is slightly smaller than the inner diameter of the inner tube 9; swing sliding protrusions 14 are provided on both sides of the swing ring 13, and the inner cavity of the inner tube 9 is provided with swing sliding grooves 15 corresponding to the swing sliding protrusions 14. The swing ring 13 is fitted into the swing sliding grooves 15 through the swing sliding protrusions 14; six bar magnets 16 are annularly embedded on the outer side of the swing ring 13, and the magnetic poles of the magnets 16 are consistent in the left and right directions; two fixed ears 17 are provided on the side of the swing ring 13 near the rotating shaft 1, and a one-way opening plate 18 is rotatably engaged with the fixed ears 17 through a pin. The one-way opening plate 18 has a circular cross section and covers the annular cavity of the swing ring 13 when closed; the inner tube 9, outer tube 10, swing ring 13 and one-way opening plate 18 are all made of non-metallic materials, such as plastic.

[0028] When the electromagnetic coil 12 is connected to a DC current with alternating current direction, the alternating magnetic field it generates will apply a periodic pushing force to the magnet 16 embedded on the outside of the swing ring 13, causing the swing ring 13 to slide back and forth along the swing groove 15 of the inner tube 9 via the swing sliding protrusions 14 on both sides. During the movement of the swing ring 13 toward the rotating shaft 1, under the action of water pressure, the one-way opening plate 18 closes, quickly pushing the water inside the inner tube 9 into the rotating shaft 1. When the swing ring 13 moves in the opposite direction, the one-way opening plate 18 opens under the action of water pressure, allowing the water from the water supply component to pass through the swing ring 13. The swing ring 13 swings back and forth, thereby realizing the spraying of water from the nozzle 8. During this process, the limiting ring 11 limits the reciprocating stroke of the swing ring 13 to ensure its stable movement trajectory. The non-metallic materials (such as plastic) of the inner tube 9 and the outer tube 10 avoid electromagnetic interference and liquid corrosion, ensuring the reliability of long-term operation.

[0029] like Figure 5As shown, one embodiment of the water supply assembly includes a water storage tank 19 and a rotating water guide sleeve 20. A motor bracket 21 is provided on the side of the water storage tank 19, and a water supply motor 22 is fixed to the motor bracket 21. The rotating water guide sleeve 20 has a cylindrical cavity structure. One side of the rotating water guide sleeve 20 is connected to a water supply pipe 34 via a water guide pipe 31 and a second rotating joint 24. The water guide pipe 31 is connected to the interior of the rotating water guide sleeve 20. The water supply pipe 34 is fixed to the ground or a support platform 30 via a pipe bracket (Figure...). (Not shown in the image); the other side of the rotating water guide sleeve 20 is fixed to the rotating drive shaft 25; the motor shaft of the water supply motor 22 passes through the motor bracket 21 and is fixed to the rotating drive shaft 25 via a coupling 26; four water intake pipes 27 are provided on the side of the rotating water guide sleeve 20, the water intake pipes 27 are connected to the inside of the rotating water guide sleeve 20, and a water intake component 28 is provided on the other side of the water intake pipe 27, the water intake pipe 27 is connected to the inner cavity of the water intake component 28, the water intake component 28 can be a spiral structure or a semi-circular cavity structure; such as Figure 6 As shown, the inner cavity of the rotating water guide sleeve 20 is provided with a cross partition 29 to separate the four water intake pipes 27. The water supply motor 22 drives the rotating water guide sleeve 20 and the water intake pipes 27 to rotate. When the water intake component 28 on the lower side is full of water and continues to move, the water flows into the rotating water guide sleeve 20 through the water intake pipe 27 and is transported to the electromagnetic drive component through the water guide pipe 31.

[0030] The water supply motor 22 drives the rotary drive shaft 25 to rotate, which in turn drives the rotary water guide sleeve 20 to rotate synchronously. The cross partition 29 in the inner cavity of the rotary water guide sleeve 20 divides the four water intake pipes 27 into independent channels. When the water intake component 28 at the end of each water intake pipe 27 rotates into the water storage tank 19 with the rotary water guide sleeve 20, it is filled with water by the cavity structure. When the water intake component 28 continues to rotate and leaves the liquid surface, the water flows into the interior of the rotary water guide sleeve 20 through the water intake pipe 27 under the action of gravity and centrifugal force, and is then transported to the electromagnetic drive assembly through the water guide pipe 31 and the second rotary joint 24. The partition design of the cross partition 29 for the water intake pipes 27 allows each water intake channel to work independently, preventing water flow from interfering with each other or flowing back in the inner cavity of the rotary water guide sleeve 20, and ensuring the stability and uniformity of the water delivery process.

[0031] like Figure 7 As shown, the second embodiment of the water supply assembly includes a water storage tank 19 and a water guide pipe 31 connected to the bottom of the water storage tank 19. The bottom of the water storage tank 19 is provided with support legs, and the other side of the water guide pipe 31 is connected to the water supply pipe 34 flange. The water storage tank 19 is stably supported by the bottom support legs, and the water guide pipe 31 connected to its bottom is directly rigidly connected to the water supply pipe 34 through the flange to form a fixed fluid passage. The water source stored in the water storage tank 19 flows into the water supply pipe 34 through the water guide pipe 31 under the action of gravity, and then is transported to the rotating shaft 1 and the spray pipe 3 system through the subsequent electromagnetic drive assembly, and finally sprayed out from the nozzle 8.

[0032] like Figure 8 As shown, the second embodiment of the water supply drive structure includes a water storage tank 19 and an L-shaped water supply pipe 32. One side of the water supply pipe 32 is connected to the first rotary joint 7, and the other side of the water supply pipe 32 extends into the water storage tank 19. A water pump 33 is provided at the end of the water supply pipe 32. The water in the water storage tank 19 is transported to the rotating shaft 1 and the spray pipe 3 system through the water supply pipe 32 by the water pump 33, and finally sprayed out from the nozzle 8.

[0033] like Figure 9-13 As shown, the second aspect of the present invention provides a coke powder activation furnace, including the driving device of the above embodiment, and an activation furnace 35 disposed on a support platform 30; the two sides of the activation furnace 35 are fixed to the support platform 30 by furnace body brackets 36, the output side of the activation furnace 35 is connected to an activated carbon bed filter device, and the rotating shaft 1 is rotatably fitted inside the activation furnace 35; the activation furnace 35 includes a feeding seat 37, a discharge seat 38, and an activation furnace cylinder 39, the feeding seat 37 and the discharge seat 38 are connected to the activation furnace cylinder 39, and the upper side of the feeding seat 37 is provided with a feed inlet 40. The feed inlet 40 has a conical structure and is connected to the inside of the feed seat 37. The lower side of the discharge seat 38 is provided with a discharge channel 41, which is connected to the activated carbon bed filter. The rotating shaft 1 is rotatably engaged with the side wall of the feed seat 37 and the discharge seat 38 through the bearing 42. The rotating shaft 1 is provided with a furnace body spiral guide plate 43, which corresponds to the inner cavity of the feed seat 37, the discharge seat 38, and the activation furnace cylinder 39. The rotating shaft 1 drives the furnace body spiral guide plate 43 to rotate, transporting the coke powder in the feed seat 37 to the discharge channel 41 of the discharge seat 38.

[0034] The activated carbon bed filtration device includes an activated carbon filter box 44, the upper side of which is connected to the output side of the activation furnace 35; the lower side of the activated carbon filter box 44 is a conical structure, which is connected to the input side of the screw conveyor 45; a gas separation pipe 46 is provided on the side wall of the activated carbon filter box 44, and the gas separation pipe 46 is inclined upward to prevent activated carbon from entering the interior of the gas separation pipe 46 and causing blockage; the activated carbon produced by the activation furnace 35 is discharged through the screw conveyor 45, and the generated gas is discharged through the gas separation pipe 46.

[0035] Powdered coke is added to activation furnace 35 and reacts with water at 700-950℃ to form microporous and mesoporous activated carbon. The activated carbon and gaseous products (coal gas) enter the activated carbon bed filter device together. At this time, the gaseous products naturally pass through the semi-coke particle layer during the rising process. The pore structure of the semi-coke particles is used to physically intercept and filter the dust in the gas to achieve the purpose of dust removal. The activated carbon falls to the bottom of the conical structure and is discharged by the screw conveyor 45.

[0036] Unless otherwise specified, the above methods of fixing all use common technical means employed by industry professionals, such as welding, nesting, or threaded fixing.
