Description

Technical Field

[0001] The present invention relates to the technical field of carbonization towers, and particularly to a carbonization tower for continuously preparing activated carbon by phosphoric acid catalysis. Background Art

[0002] The carbonization tower for continuously preparing activated carbon by phosphoric acid catalysis is a device for producing activated carbon. It mainly uses phosphoric acid as a catalyst to carbonize and activate raw materials during the continuous production process, and finally obtains activated carbon products. The core of preparing activated carbon by phosphoric acid catalysis is to use phosphoric acid as a catalyst to promote the carbonization and activation processes of raw materials. Phosphoric acid can reduce the carbonization temperature, accelerate the decomposition of organic substances, and form a rich pore structure during the activation process, thereby improving the adsorption performance of activated carbon.

[0003] When the materials in the existing vertical carbonization tower for continuously preparing activated carbon are carbonized in the carbonization zone, the materials fall by their own gravity, and it is not possible to well control the material speed, resulting in poor carbonization effect. At the same time, the materials continuously enter the inside of the carbonization tower, and the materials are prone to accumulate and block inside. Therefore, the present application provides a carbonization tower for continuously preparing activated carbon by phosphoric acid catalysis to meet the requirements. Summary of the Invention

[0036] As shown in the figure, in order to clearly show the structure of the embodiments of the present invention, specific structures and devices are marked in the figure, but this is only for schematic purposes and is not intended to limit the present invention to this specific structure, device and environment. Those of ordinary skill in the art can adjust or modify these devices and environments according to specific needs. Detailed embodiments

[0037] The following will describe in detail a carbonization tower for continuously preparing activated carbon catalyzed by phosphoric acid provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0038] As Figures 1 to 13 shown, an embodiment of the present invention provides a carbonization tower for continuously preparing activated carbon catalyzed by phosphoric acid, including a base 1. The base 1 is used to fixedly connect the entire carbonization tower to the ground to prevent collapse. The top of the base 1 is fixedly connected with a housing unit 2. The housing unit 2 is connected by a plurality of tower body shells 22 fixedly connected in sequence. An outlet 221 is provided on the outer surface of the lowermost tower body shell 22. The top of the uppermost tower body shell 22 is fixedly connected with a tower top shell 21. An inlet 211 is provided at the top of the tower top shell 21. By splicing a plurality of tower body shells 22, users can adjust and design the height of the tower body of the carbonization tower according to actual working requirements. The inlet 211 and the outlet 221 are respectively connected to an external screw feeder. A connecting ring plate 23 is fixedly connected to the inner surface of the tower body shell 22 at the middle position. A carbonization and activation cylinder 3 is fixedly connected to the inner circle of the connecting ring plate 23. The carbonization and activation of materials are realized inside the carbonization and activation cylinder 3. The top end of the carbonization and activation cylinder 3 is communicated with the inlet 211, and the bottom end of the carbonization and activation cylinder 3 is communicated with the inlet of the screw feeder installed on the outlet 221, so that the processes of feeding, carbonization, activation and discharging of materials are all completed inside the carbonization and activation cylinder 3. A partition plate 31 is fixedly connected to the inner surface of the carbonization and activation cylinder 3 at a position corresponding to the connecting ring plate 23. A plurality of uniform partition holes 311 are provided on the partition plate 31. The partition plate 31 is used to divide the inside of the carbonization and activation cylinder 3 into two areas. The area above the partition plate 31 is the carbonization area, and the area below the partition plate 31 is the activation area. The carbonization area is used to thermally decompose materials to form an initial carbon skeleton and pore structure. The activation area enlarges and increases the volume of the pores of the materials through oxidation reaction to improve the adsorption performance. Among them, the activation area is a prior art;

[0039] It also includes a anti-clogging shunt device 5, which is located on the inner surface wall of one end of the carbonization activation cylinder 3, and the anti-clogging shunt device 5 is connected to the carbonization activation cylinder 3. The anti-clogging shunt device 5 is used for shunting and anti-clogging of the material to be carbonized. The anti-clogging shunt device 5 includes a semi-spherical shunt ball 51. The diameter of the shunt ball 51 is smaller than the cylinder diameter at the top of the carbonization activation cylinder 3. The gap between the shunt ball 51 and the carbonization activation cylinder 3 can pass the material. By installing shunt balls 51 with different diameters to adapt to materials of different sizes, four connecting rods 52 are evenly fixed on the outer surface wall of the bottom end of the shunt ball 51. The shunt ball 51 is fixedly connected to the inner surface wall of the carbonization activation cylinder 3 through the four connecting rods 52. Every two adjacent connecting rods 52 are distributed at 90°. A number of connecting columns 54 evenly distributed in a ring are evenly connected to the outer surface wall of the shunt ball 51. A material ejecting strip 53 is correspondingly connected to each connecting column 54. When the material passes through, the material ejecting strip 53 will be slightly deformed due to the extrusion of the material, increasing the space for the material to pass through. An installation column 8 is connected between the anti-clogging shunt device 5 and the partition plate 31. A spiral feeding strip 6 is fixedly connected to the outer surface wall of the installation column 8. The spiral feeding strip 6 is of a spiral structure. The two sides of the spiral feeding strip 6 are hermetically connected to the outer surface wall of the installation column 8 and the inner surface wall of the carbonization activation cylinder 3 respectively. Therefore, the material falling through the anti-clogging shunt device 5 can only pass through the spiral feeding strip 6. A material adjusting device 9 is connected to the installation column 8. The installation column 8 is used to provide installation positions for the spiral feeding strip 6 and the material adjusting device 9. The outer surface wall of the material adjusting device 9 is connected with an adjusting spiral strip 7. The material adjusting device 9 is used to adjust the adjusting spiral strip 7. By driving the up and down movement of the adjusting spiral strip 7 through the material adjusting device 9, the passing speed of the material on the spiral feeding strip 6 is adjusted. At the same time, when the material is blocked on the spiral feeding strip 6, the reciprocating movement of the adjusting spiral strip 7 can loosen the material to prevent the material from being blocked on the spiral feeding strip 6. Both the spiral feeding strip 6 and the adjusting spiral strip 7 are of spiral structures, and the spiral feeding strip 6 is located above the adjusting spiral strip 7;

[0040] It also includes a temperature adjusting device 4, which is located in the gap between the inner surface wall of the tower body shell 22 and the outer surface wall of the carbonization activation cylinder 3. The temperature adjusting device 4 is used to provide the carbonization temperature and evenly distribute the internal temperature around the carbonization activation cylinder 3.

[0041] Such as Figures 2 to 5As shown, the elastic material strip 53 is fixedly connected by an elastic material section 531 and a driving section 532. The driving section 532 is an arc-shaped structure with an inner concave shape, and the elastic material section 531 is an arc-shaped structure with an outward turning shape. One side of the connecting column 54 is hinged at the connection position of the elastic material section 531 and the driving section 532. The driving section 532 is made of a rigid material, and the elastic material section 531 is made of an elastic material. The elastic material section 531 can automatically adjust the opening size according to the particle size, humidity, and viscosity of the material, adapting to different types of raw materials. Its elastic deformation can prevent the material from forming a hard accumulation when passing through the edge, and its manufacturing cost is low, and it is easy to install and maintain. The anti-blocking and shunting device 5 further includes an extrusion unit for extruding the driving section 532. The extrusion unit can extrude the driving section 532 under the impact of the falling material, thereby driving the elastic material section 531 to vibrate. When the material is blocked, the elastic material section 531 can loosen the blocked material through vibration. The extrusion unit includes a sliding groove 59 opened at the top of the shunting ball 51. A reset groove 58 is opened on the inner surface wall of the sliding groove 59. A sliding rod 57 is slidably connected to the inner surface wall of the sliding groove 59. The sliding rod 57 is adapted to the sliding groove 59. The top of the sliding rod 57 is fixedly connected with an extrusion cover 55. The extrusion cover 55 is an umbrella-shaped structure. When the umbrella-shaped extrusion cover 55 drops the material, it can guide the material to the gap between the shunting ball 51 and the carbonization activation cylinder 3. A reset spring 56 is arranged inside the reset groove 58. The two ends of the reset spring 56 are respectively fixedly connected to the outer surface wall of the sliding rod 57 and the bottom of the reset groove 58.

[0042] The material to be carbonized enters the feeding port 211 from the external screw feeder. The material drops from the feeding port 211 to the extrusion cover 55 on the anti-blocking and shunting device 5, and then is guided by the extrusion cover 55 to the gap between the shunting ball 51 and the carbonization activation cylinder 3, and thus drops onto the screw feeding strip 6 through the gap. When there is more material, the material will squeeze the elastic material section 531 when passing through the gap between the shunting ball 51 and the carbonization activation cylinder 3, causing the elastic material section 531 to be squeezed and deformed, thereby increasing the gap between the shunting ball 51 and the carbonization activation cylinder 3 to facilitate the passage of the material. At the same time, the subsequent material dropping from the feeding port 211 will impact the extrusion cover 55. When the extrusion cover 55 is impacted, the connected sliding rod 57 slides on the sliding groove 59. At this time, the edge position of the extrusion cover 55 will squeeze the driving section 532, and the driving section 532 will be displaced downward under the extrusion, and the elastic material section 531 will be driven to vibrate during the displacement. The blocked material is loosened by the vibrating elastic material section 531. When there is no material impact on the extrusion cover 55, the reset spring 56 will drive the sliding rod 57 to return to the initial position.

[0043] As Figure 2 、 Figures 6 to 9As shown, the temperature control device 4 includes a gas heating pipe 43 fixedly connected to the top of the connecting ring plate 23 and a heat conducting sleeve 42 sleeved on the outer wall of the carbonization activation cylinder 3. The heat conducting sleeve 42 and the gas heating pipe 43 are connected and communicated through a diversion ring piece 41. The gas heating pipe 43 is used to provide heating temperature for material carbonization. The heat conducting sleeve 42 is used to wrap the carbonization area of the carbonization activation cylinder 3, so that a uniform heating area is formed between the heat conducting sleeve 42 and the carbonization activation cylinder 3. The diversion ring piece 41 is used to direct the high-temperature gas flow generated by the gas heating pipe 43 into the heat conducting sleeve 42. The high-temperature gas flow can be gathered by the heat conducting sleeve 42 to directly heat the carbonization activation cylinder 3. At the same time, the internal high-temperature gas flow is homogenized by the diversion spiral piece 423 to increase the carbonization effect of the material inside the carbonization activation cylinder 3. A plurality of gas heating pipes 43 are provided, and the plurality of gas heating pipes 43 are evenly distributed in a ring on the top of the connecting ring plate 23. A plurality of evenly distributed nozzles 431 are communicated with each gas heating pipe 43. The nozzles 431 are inclined towards the heat conducting sleeve 42, and the inclination direction of the nozzles 431 forms an angle of 30° with the axis of the gas heating pipe 43. Sealing openings 424 are provided at both ends of the heat conducting sleeve 42. The diameter of the sealing openings 424 is the same as the diameter of the carbonization activation cylinder 3. The inner wall of the heat conducting sleeve 42 is fixedly connected with a diversion spiral piece 423. A plurality of inlet holes 421 evenly distributed in a ring are opened at one end of the heat conducting sleeve 42 close to the diversion ring piece 41. The orientation of the inlet holes 421 is the same as the spiral direction of the diversion spiral piece 423. A plurality of evenly distributed outlet holes 422 are opened on the outer wall of the bottom of the heat conducting sleeve 42. The diversion ring piece 41 is formed by connecting two converging sections 412, two diversion sections 413 and an outlet section 414. The bottoms of the two symmetrically distributed converging sections 412 are respectively fixedly connected with the outer wall of the heat conducting sleeve 42 and the inner wall of the tower body shell 22. The same-direction ends of the two converging sections 412 are respectively connected with a diversion section 413. The ends of the two diversion sections 413 far from the converging sections 412 are fixedly connected through the outlet section 414. A guiding pipe 411 corresponding to the inlet holes 421 is fixedly connected to the outer wall of the outlet section 414. The guiding pipe 411 is adapted to the inlet holes 421. When the high-temperature gas flow enters the diversion section 413 through the converging section 412, the passing path becomes narrower, so as to accelerate the high-temperature gas flow. The carbonization activation cylinder 3 is isolated from the gas heating pipe 43 through the heat conducting sleeve 42, avoiding the phenomenon that the gas heating pipe 43 directly acts on the outer wall of the carbonization activation cylinder 3, resulting in uneven temperature inside the carbonization activation cylinder 3. At the same time, the temperature inside the heat conducting sleeve 42 is homogenized by the diversion spiral piece 423.

[0044] When the nozzle 431 is heated by combustion, it can drive the heated air flow to move towards the direction of the flow guiding ring 41. The high-temperature air flow enters between the two converging sections 412 under the impact of the air flow heated by the nozzle 431, then enters the guiding section 413 through the two converging sections 412, and then enters the heat equalizing sleeve 42 through the guiding pipe 411 and the inlet hole 421. Since the high-temperature air flow ejected from the guiding pipe 411 is in the same rotation direction as the flow guiding spiral 423, the high-temperature air flow will rotate and move along the rotation direction of the flow guiding spiral 423. Finally, the high-temperature air flow enters the area where the gas heating pipe 43 is located through the outlet hole 422, thus forming a cycle.

[0045] As Figure 2 , Figures 10 to 13 shown, the mounting post 8 is a hollow cylindrical structure inside. The inside of the mounting post 8 is used to provide a mounting position for the material adjusting device 9. The two ends of the mounting post 8 are respectively fixedly connected to the bottom of the shunt ball 51 and the top of the partition plate 31. Four first sliding grooves 81 evenly distributed in a ring shape are formed on the outer surface wall of the mounting post 8. The first sliding grooves 81 are used to provide a sliding track for the first slider 95. A second sliding groove 82 communicating with the inside of the mounting post 8 is formed at the middle position on the inner side of the first sliding groove 81. The second sliding groove 82 is used to provide a sliding track for the second slider 94; The material adjusting device 9 includes a connecting bearing 92 fixedly connected to the inner surface wall of the mounting post 8. A lead screw 91 is rotatably connected to the inner surface wall of the connecting bearing 92. The lead screw 91 is a prior art. The top of the lead screw 91 is rotatably connected to one end of the mounting post 8. A nut seat 93 is arranged on the outer surface wall of the lead screw 91. A second slider 94 is fixedly connected to the position corresponding to the second sliding groove 82 on the outer surface wall of the nut seat 93. A first slider 95 is fixedly connected to the side of the second slider 94 away from the nut seat 93. The position where the outer surface wall of the first slider 95 contacts the adjusting spiral strip 7 is fixedly connected; The length of the first slider 95 is less than the length of the first sliding groove 81, and the length of the second slider 94 is less than the length of the second sliding groove 82; Adjusting columns 71 are evenly and fixedly connected to the surface of the adjusting spiral strip 7 on the side close to the spiral feeding strip 6. Adjusting holes 61 are formed at the positions corresponding to the adjusting columns 71 on the surface of the spiral feeding strip 6.

[0046] When it is necessary to adjust the material on the surface of the spiral feeding strip 6, the lead screw 91 drives the second slider 94 and the first slider 95 fixed on the nut seat 93 to move reciprocally. When the first slider 95 is displaced, it drives the adjusting spiral strip 7 fixed on the first slider 95 to be displaced. When the adjusting spiral strip 7 is displaced, it drives the adjusting columns 71 on the surface of the adjusting spiral strip 7 to slide on the adjusting holes 61. By adjusting the length of the adjusting columns 71 extending on the adjusting holes 61, the speed of the material on the surface of the spiral feeding strip 6 can be adjusted through the adjusting columns 71.

[0047] The working principle of the technical solution provided by the present invention is as follows: Connect the feeding port 211 and the discharging port 221 to an external screw feeder respectively. Feed the material to be carbonized impregnated with phosphoric acid to the feeding port 211 through the screw feeder. After the material to be carbonized enters the feeding port 211 from the external screw feeder, the material drops from the feeding port 211 to the pressing cover 55 on the anti-blocking and shunting device 5, and then is guided by the pressing cover 55 to the gap between the shunting ball 51 and the carbonization and activation cylinder 3, and thus drops to the screw feeding strip 6 through the gap.

[0048] At the same time, when the spray pipe 431 is burning and heating, it can drive the heated air flow to move towards the direction of the guide ring piece 41. The high-temperature air flow enters between the two converging sections 412 under the impact of the heated air flow of the spray pipe 431, then enters the diversion section 413 through the two converging sections 412, and then enters the soaking sleeve 42 through the guide pipe 411 and the inlet hole 421. Since the high-temperature air flow ejected from the guide pipe 411 is in the same rotation direction as the diversion spiral piece 423, the high-temperature air flow will rotate and move along the rotation direction of the diversion spiral piece 423. Finally, the high-temperature air flow enters the area where the gas heating pipe 43 is located through the outlet hole 422, thus forming a cycle, and the material inside the carbonization and activation cylinder 3 is subjected to high-temperature carbonization through the soaking sleeve 42.

[0049] During the carbonization process, according to the actual material flow situation, the material on the surface of the screw feeding strip 6 can be adjusted. The second slider 94 and the first slider 95 fixed on the nut seat 93 are driven by the lead screw 91 to perform reciprocating motion. When the first slider 95 is displaced, the adjusting screw strip 7 fixed on the first slider 95 is driven to be displaced. When the adjusting screw strip 7 is displaced, the adjusting column 71 on the surface of the adjusting screw strip 7 is driven to slide on the adjusting hole 61. By adjusting the length of the adjusting column 71 extending on the adjusting hole 61, the speed of the material on the surface of the screw feeding strip 6 can be adjusted through the adjusting column 71.

[0050] The carbonized material on the surface of the screw feeding strip 6 will enter the activation area through the separation hole 311 on the separation plate 31 to perform activation work, and the material after the activation work falls from the bottom end of the carbonization and activation cylinder 3 into the screw feeder inlet installed on the discharging port 221.
