Description

Technical Field

[0001] The invention relates to the field of activated carbon regeneration, and in particular to a pyrolysis device for activated carbon regeneration. Background Art

[0002] According to the appearance of activated carbon, it includes powdered activated carbon and granular activated carbon. Among the activated carbon regeneration methods, thermal regeneration is the most mature activated carbon regeneration method; in the regeneration process of activated carbon, according to the changes of organic matter when heated to different temperatures, it is generally divided into three stages: drying, high-temperature carbonization and activation; in the drying stage, volatile components such as moisture on the activated carbon are removed; in the high-temperature carbonization stage, part of the organic matter adsorbed on the activated carbon is vaporized and desorbed, and part of the organic matter is decomposed and desorbed as small molecules, and the remaining components remain in the pores of the activated carbon to become fixed carbon; in the activation stage, gases such as CO2, CO or water vapor are introduced to clean the micropores of the internal structure of the activated carbon to restore its adsorption activity; the core of the regeneration process is the activation stage; the thermal regeneration method has a relatively high regeneration efficiency, a short time, and a wide range of applications.

[0003] Desulfurization and denitrification activated carbon is usually in strip shape. The main purpose of setting it in strip shape is to improve mechanical strength, facilitate regeneration and repeated use. Desulfurization and denitrification activated carbon in strip shape loses its adsorption capacity after a period of use. It will begin to decompose or release certain substances to form flocs. The surface area of ​​desulfurization and denitrification activated carbon in strip shape is larger than that of granular activated carbon, and it is easy to produce stickiness after contact.

[0004] After denitrification and desulfurization, the strip-shaped activated carbon for desulfurization and denitrification will form sticky lumps. During the pyrolysis process in the rotary furnace, the strip-shaped activated carbon will stick together to form large lumps, which increases the difficulty of thermal decomposition and is not conducive to the full thermal decomposition of the activated carbon in the rotary furnace. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a pyrolysis device for regenerating activated carbon.

[0013] It should be understood that in the process of the driving assembly driving the rotating tube to rotate, the first movable tube is synchronously acted on so that the first movable tube is intermittently pushed. In the process of the first movable tube being pushed, the first movable tube will synchronously pull the second movable tube to move along the upward direction of the inner part of the rotating tube, thereby driving the paddle and the plow to move synchronously, and the strip-shaped desulfurization and denitrification activated carbon moving downward along the inclined direction of the rotating tube is plowed, and the plow will plow the accumulated activated carbon to realize turning over the accumulated activated carbon, which is beneficial to increase the fluidity of the activated carbon on the one hand, and on the other hand, it is beneficial to scatter the sticky activated carbon, so that the surface of a single activated carbon can be fully exposed, which is beneficial to the full pyrolysis of the activated carbon;

[0015] During the discharge process, the activated carbon flowing from the inner part of the rotating tube will be collected at the connection point between the spiral discharge tube and the rotating tube. When the connection point between the spiral discharge tube and the rotating tube is at the bottom, the activated carbon will flow into the spiral discharge tube, and then as the spiral discharge tube rotates, the material will gradually flow to the tail end of the spiral discharge tube to achieve discharge;

[0016] During the smoke exhaust process, the smoke generated during the pyrolysis process will be squeezed into the second movable tube through the exhaust hole, and then discharged through the first movable tube. It can be connected to the first movable tube through an external pipeline to discharge the smoke into the smoke purification equipment and then discharged after purification.

[0017] As a further embodiment of the present invention, the drive assembly comprises:

[0018] A linkage gear ring, wherein the linkage gear ring is fixedly connected to the end of the rotating tube;

The second protrusion will synchronously drive the second movable tube to move through the linkage plate, thereby realizing the pushing of the second movable tube. There is a distance between the multiple second protrusions, so when moving between the multiple protrusions, an interval is formed. Therefore, in the process of passing through the multiple second protrusions, a gap push is formed, thereby realizing the gap to move the toggle blade and the toggle plow.

[0029] A cooling pool is provided with water, and is used to immerse the bottom end of the spiral discharge pipe in the water inside the cooling pool at all times.

[0030] It should be understood that in the process of activated carbon after thermal decomposition being discharged from the rotating tube, it is through the connection between the spiral discharge pipe and the rotating tube when it is in a lower position, that is, close to the cooling pool, so that the activated carbon in the rotating tube is limitedly entered into the spiral conveying pipe, and it will contact with the water in the cooling pool to achieve initial cooling. Then the spiral conveying pipe will drain and transport the activated carbon during rotation, and the spiral discharge pipe is always in contact with the water in the cooling pool. Therefore, the spiral conveying pipe itself is always in contact with cold water to be cooled, and when the activated carbon is transported to the bottom, it will contact with the position where the spiral discharge pipe contacts the water in the cooling pool, and it will be cooled directly at the source of cooling, which is beneficial to further improve the cooling capacity.

[0044] Compared with the prior art, the present invention has the following beneficial effects:

[0045] In the present invention, during the process of thermally decomposing activated carbon by a rotary furnace, when the rotary furnace is driven to rotate, the paddles and the paddle plough are synchronously and intermittently driven to move, and the strip-shaped desulfurized and denitrified activated carbon moving downward along the inclined direction of the rotary tube is paddled, and the paddle plough plows the accumulated activated carbon to realize turning over the accumulated activated carbon, which is beneficial to increasing the fluidity of the activated carbon on the one hand, and is beneficial to scattering the sticky activated carbon on the other hand, so that the surface of a single activated carbon can be fully exposed, which is beneficial to fully thermally decomposing the activated carbon;

[0046] The spiral conveying pipe itself is always in contact with cold water to be cooled, and when the activated carbon is conveyed to the bottom, it will come into contact with the position where the spiral discharge pipe contacts the water in the cooling pool, directly cooling down at the cooling source, which is beneficial to further improve the cooling capacity. Therefore, in the process of discharging, the activated carbon after thermal decomposition is always cooled, and in the process of cooling, there is spiral conveying of the activated carbon, so that the activated carbon can be turned over in the spiral discharge pipe and can be evenly contacted with the inner wall of the spiral discharge pipe, which is beneficial to speed up the cooling speed of the activated carbon.

[0047] During the process of water spraying from the water pipe, water will fall on the surface of the receiving part, causing an impact on the receiving part, and then pushing the edge of the entire linkage ring, causing the linkage ring to rotate, and then the linkage ring will synchronously drive the second movable tube to rotate and shake, and the second movable tube will synchronously drive the shifting blade and the shifting plow to flip and move, and the second movable tube is moved by the driving assembly, realizing multi-directional effects, so that the shifting blade and the shifting plow can generate multi-directional movements, which is conducive to multi-directional shifting of the activated carbon, improving the fluidity of the activated carbon, and increasing the possibility of scattering sticky activated carbon.

[0048] When the receiving part is a plate-like blade, the water sprayed from the water spray pipe will fall on the surface of the plate-like blade to achieve propulsion, and under the impact, the water column will splash, which is conducive to further contact between the water after cooling treatment and the air, so as to achieve cooling, thus preparing for the subsequent further cooling of the activated carbon.

When the amount of water received by the water receiving scoop increases, the possibility of the linkage ring to rotate will increase, and then the possibility of the linkage ring driving the second movable tube to rotate will increase, that is, the possibility of driving the turning blades and the turning plow to turn over will increase, which is conducive to driving the turning blades and the turning plow to turn the activated carbon in multiple directions.

[0079] During the rotation of the linkage gear ring 18, the first protrusion 22 will be driven to move, and the first protrusion 22 will interact with the second protrusion 23 to push the second protrusion 23. The second protrusion 23 synchronously drives the second movable tube 13 to move through the linkage plate 21, thereby realizing the pushing of the second movable tube 13.

On the one hand, the water in the cooling pool 26 can be shaken, which is beneficial to accelerate the flow of water and heat dissipation. On the other hand, the cover 30 can block the water sprayed from the water spray pipe 29 to prevent the water from spraying out and affecting the working environment.

[0093] It should be noted that during the movement of the water storage shell 27, when the water storage shell 27 passes through the water in the cooling pool 26, water will enter the water inlet 28, and the water will be collected in the water storage shell 27 until the water storage shell 27 moves out of the cooling pool 26. There is still water in the water storage shell 27, which can continuously cool the part of the spiral discharge pipe 7 in the water storage shell 27.

[0103] It should be understood that by setting the gravity plate 34, when the water storage shell 27 is flipped to the state of spraying water through the water spray pipe 29, the gravity plate 34 will squeeze the water in the water storage shell 27 under the action of gravity, thereby increasing the spray force of the water, which is conducive to pushing the receiving part, thereby increasing the possibility of driving the moving blade 16 and the moving plow 17 to flip.

[0104] As a further embodiment of the present invention,

[0105] Three sealing plates 35 are fixedly connected to the top of the gravity plate 34. The three sealing plates 35 are respectively in contact with the inner side walls of the water storage shell 27. The sealing plates 35 are used to shield the water inlet 28 when the gravity plate 34 moves to push water.

[0106] It should be understood that when the gravity plate 34 moves to squeeze the water, the sealing plate 35 will block the water inlet 28 to reduce the outflow of water in the water storage shell 27.

[0107] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
