Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pyrolysis devices, in particular to an activated carbon anoxic pyrolysis and steam regeneration device. BACKGROUND

[0002] In the field of activated carbon pyrolysis regeneration treatment technology, the pipe arrangement and screen pipe structure design in the regeneration tank directly affect the regeneration efficiency and equipment service life. At present, the industry generally connects the pipe for steam injection with the branch outside the tank, and realizes the layered arrangement of the pipe along the circumferential direction of the tank wall through flanges, buckles and other fixing parts to form an annular pipe system. However, in actual operation, obvious defects are exposed: during the thermal regeneration process, the airflow temperature in the tank fluctuates violently, the pipe is significantly affected by the working hot airflow and expands and contracts, and the rigid fixing method of flanges, buckles and the like cannot offset the above deformation stress, resulting in a gap gradually formed between the pipe and the fixed structure; the existence of the gap causes the pipe to shake irregularly under the impact of the airflow, causing the steam injection position to deviate, and further causing the activated carbon in the tank to be unevenly heated, the stripping effect to be significantly different, and in severe cases, even the local carbon layer to be overheated and carbonized or not completely regenerated, greatly reducing the quality of activated carbon regeneration.

[0003] At the same time, the screen pipe in the regeneration tank, as the core component supporting the activated carbon layer, is subjected to complex mechanical load tests for a long time. The activated carbon forms a carbon layer in a stacked state, and the screen pipe needs to continuously bear the gravity load of the particles above; during the non-blowing stage (such as the pre-treatment heating and the later cooling process), the carbon layer lacks the upward lifting force of the steam airflow, the activated carbon particles naturally settle due to gravity, the gap between the particles decreases, and the extrusion force on the screen pipe significantly increases; during the blowing stage, the airflow lifting force temporarily relieves this pressure, forming a periodic load change; the existing screen pipe design is not optimized for this dynamic mechanical environment, and lacks effective buffer and stress dispersion structures, resulting in plastic deformation of the screen pipe under long-term periodic load; in the early stage of deformation, it is characterized by a change in screen hole size and a decrease in steam permeability efficiency, and as the deformation intensifies, serious faults such as screen pipe rupture and carbon layer collapse occur, which not only interrupt the regeneration process, but also cause the activated carbon particles to enter the steam pipe, resulting in system blockage, increasing equipment maintenance costs and downtime.

[0004] The design defects of the above-mentioned pipe fixing and screen pipe structure have become a key bottleneck restricting the stability and economy of activated carbon thermal regeneration technology, and need to be solved through technological innovation.

[0005] Therefore, the present application provides an activated carbon anoxic pyrolysis and steam regeneration device to solve the above problems. SUMMARY

[0024] Compared with the prior art, the present invention provides an activated carbon anoxic pyrolysis and steam regeneration device, which has the following beneficial effects:

[0025] 1. The overall design of the first component of the present invention can bring the following benefits:

[0026] Improved piping system stability and reliability: By restricting and fixing the annular injection pipeline between ring seat A and ring seat C, and by matching the high-temperature resistant sleeve A with the support ring, different from the existing fixing method, it can effectively eliminate the gap problem caused by thermal expansion and contraction, avoid the gap caused by rigid fixation, solve the problem of pipeline shaking from the root, and ensure uniform heating and stripping. The stable pipeline position and precise steam injection can ensure that the activated carbon in the tank is heated evenly. During the stripping process, the steam and carbon layer are in full contact, avoiding local overheating or incomplete regeneration, and improving the regeneration quality and adsorption performance of the activated carbon.

[0027] Resisting the extrusion impact of particle sedimentation: During the non-stripping activation stage, such as pretreatment and cooling processes, the damping ring in the first component can provide additional support and protection for the pipeline, buffering and offsetting the extrusion force during the sedimentation of activated carbon particles, preventing the pipeline from deformation or displacement due to external forces, and ensuring the structural integrity of the pipeline system.

[0028] 2. The present invention uses the design of an air interlayer to address the extrusion and thermal shock problems faced by the annular injection pipeline and fixed components during the thermal regeneration of activated carbon, which can assist in further optimization of the first component, as follows:

[0029] Buffer external extrusion and protect the annular injection pipeline structure: The air interlayer can act as an elastic buffer barrier. When the activated carbon particles settle and cause extrusion in the non-stripping stage, it can effectively absorb and disperse the impact force, reducing the direct hard impact of the activated carbon particles on the annular injection pipeline. This not only reduces the probability of physical damage such as deformation and cracking of the pipeline due to continuous extrusion, but also delays the degradation of the mechanical properties of the pipeline material, such as avoiding the loss of strength and toughness caused by long-term stress on the pipeline, thereby extending the service life of the annular injection pipeline and ensuring its stable steam injection function.

[0030] Form a thermal insulation barrier to reduce the risk of thermal damage to fixed components: During the thermal regeneration process, high-temperature gas circulates in the desorption tank, and the air interlayer can block part of the heat transfer, reducing the direct thermal impact of high temperature on the fixed components of the annular injection pipeline; it helps to reduce the degradation of material properties of fixed components due to long-term exposure to high temperature environments, such as avoiding accelerated oxidation, reduced hardness, and increased brittleness of metal fixings due to high temperature, ensuring the connection strength and stability of the fixed components, and thus maintaining the overall structural stability of the annular pipeline system, reducing problems such as loosening and offset of pipelines due to failure of fixed components.

[0031] 3. The design of the granular ball in the present invention aims to solve the pipeline impact problem caused by the sedimentation of activated carbon particles in the non-blowing stage. The multi-dimensional optimization is achieved through the characteristics of the raised structure. The specific beneficial effects are as follows:

[0032] Increase inter-particle friction, slow down the settling of activated carbon particles, and reduce instantaneous impact on pipelines: When the convex structure of the granular ball contacts the activated carbon particles, it can form more "bite points" compared to a flat structure, significantly increasing the friction and mechanical resistance between the particles, hindering the rapid sliding of activated carbon particles under the action of gravity, thereby slowing the settling rate in the non-blowing stage; the more gradual settling rate can effectively avoid the concentrated instantaneous pressure caused by rapid settling, reducing the risk of deformation and cracking caused by sudden loads in the annular injection pipeline protected by the baffle plate, and protecting the integrity of the pipeline structure;

[0033] Maintain stable gaps between particles, optimize the stress state of the system, and reduce the shrinkage of gaps: The raised structure can maintain relative stability of the gaps between activated carbon particles in the non-blowing stage by enhancing the mutual support between particles, avoiding a sharp decrease in the gaps caused by dense accumulation of particles. At the same time, the stable gaps between particles can reduce the final settling distance of the activated carbon particles, making the overall height change of the particle layer smoother, and effectively reducing the load pressure of the baffle plate, thereby reducing the lateral extrusion force on the annular injection pipeline.

[0034] 4. The present invention can bring the following benefits through the cooperation between the grille tube body and the annular reinforcement ribs:

[0035] Disperse gravity loads and protect the integrity of the porous screen tube structure: The curved surface design of the annular reinforcement ribs can evenly disperse the local gravity load of the activated carbon particles to a larger contact area, avoiding load concentration in a certain area; at the same time, the load is transmitted to the entire grid tube body through the annular reinforcement ribs, so that the force is transferred from a single screen tube to the overall structure, greatly reducing the risk of bending and extrusion deformation of the porous screen tube due to long-term exposure to concentrated gravity.

[0036] 5. The present invention can achieve the following beneficial effects by designing the wing edge as an inclined surface:

[0037] Reduce pressure and reduce the risk of structural damage: The inclined design expands the contact area between the airfoil and the activated carbon particles, so that the particle gravity load and lateral extrusion force are more evenly distributed on the airfoil surface; this directly reduces the deformation, cracking and other damage to the airfoil itself due to long-term concentrated stress, thereby extending the service life of the airfoil; at the same time, it can alleviate the extrusion of the activated carbon particles on the surrounding components; that is, due to the reduction in pressure per unit area, the interaction force between the activated carbon particles and the airfoil is smoother when in contact, which can reduce the indirect extrusion of the particles on the components around the airfoil, avoid pipeline deformation or functional failure due to excessive local pressure, and indirectly protect the structural integrity of the core components of the system.

[0058] The first component 7 is also provided in the inner cavity of the desorption tank 1; the first component 7 includes a baffle plate A701 slidably connected to the inner wall of the desorption tank 1, a damping ring A702 is fixedly connected to the bottom surface of the baffle plate A701, a ring seat A703 is fixedly connected to the bottom end of the damping ring A702, and the ring seat A703 is fixedly connected to the inner cavity wall of the desorption tank 1; a support ring 705 is equidistantly sleeved on the annular injection pipeline 5, and a high-temperature resistant sleeve A704 is sleeved on the annular injection pipeline 5 through the support ring 705, and the annular injection pipeline 5 Together with the inner cavity of the high-temperature resistant sleeve A704, it forms an air interlayer 706; a ring seat C709 is fixedly connected to the inner wall of the desorption tank 1, a damping ring B708 ​​is fixedly connected in the groove of the ring seat C709, a baffle plate B707 is fixedly connected to the lower surface of the damping ring B708, and the baffle plate B707 is slidably connected to the inner cavity of the desorption tank 1; granular balls 710 are fixedly connected at equal distances on the baffle plate A701; a support grid plate 3 is provided under the first component 7, and the support grid plate 3 is fixedly connected to the bottom of the inner cavity of the desorption tank 1.

[0059] in:

[0060] The desorption tank 1 is provided with equipment connecting pipelines such as a cooling water pipe and an auxiliary delivery pipe.

[0061] The carbon inlet tube 2 is used for transporting activated carbon.

[0062] The annular injection pipeline 5 can be adaptively opened according to the usage; and the number can be increased or decreased.

[0063] The steam injection pipe 4, the annular injection pipeline 5, and the porous screen tube 6 together constitute a steam delivery unit. When in use, the annular injection pipeline 5 and the porous screen tube 6 between each unit can be connected through the steam injection branch, and installation grooves are reserved for relevant components in the device.

[0064] The first component 7 is used in the stripping activation stage and the non-stripping activation stage to ensure that the pipeline is installed and fixed, and to avoid extrusion and deformation of the pipeline caused by thermal expansion and contraction and the sedimentation of activated carbon particles in the non-gas-supported state.

[0065] The blocking plate A701, the damping ring A702, and the ring seat A703 form a group, and the blocking plate B707, the damping ring B708, and the ring seat C709 form a group. The two groups together provide support for protection.

[0066] The high temperature resistant casing A704 material is implemented as ceramic fiber composite material.

[0067] The buffer interlayer can form a buffer barrier, reduce the direct impact of external extrusion on the annular injection pipeline 5, and reduce the attenuation of the mechanical properties of the material caused by extrusion.

[0068] The baffle plate and damping ring reduce the periodic pressure shock to the pipeline by controlling the sedimentation and gap changes of the activated carbon layer.

[0069] The elastic deformation gaps of the damping ring A702 and the damping ring B708 ​​are staggered.

[0070] The raised structure of the granular ball 710 is different from the planar structure. It can increase the friction between it and the activated carbon particles, maintain the relative stability of the gap between the particles, slow down the sedimentation rate of the activated carbon particles in the non-blowing stage, and indirectly reduce the instantaneous impact force on the high-temperature resistant sleeve A704 on which the annular injection pipeline 5 is installed; and the raised structure can increase the friction between the particles, maintain the relative stability of the gap between the particles, and shorten the sedimentation distance.

[0071] Further examples: Please refer to Figure 2 、 Figures 5 to 10 As shown:

[0072] It also includes a carbon inlet pipe 2 fixedly connected to the top of the desorption tank 1 in a through-type manner, and a second component 8 is provided below the carbon inlet pipe 2; the second component 8 includes a grid tube body 801 sleeved on the porous screen tube 6, and a high-temperature resistant sleeve B802 is sleeved on the grid tube body 801, and an annular reinforcement rib 803 is equidistantly arranged around the high-temperature resistant sleeve B802, and a through hole 804 is opened through the annular reinforcement rib 803, and a transverse groove is opened in the annular reinforcement rib 803, and a spring A805 is fixedly connected to the inner wall of the transverse groove of the annular reinforcement rib 803; the other end of the spring A805 is fixedly connected to a wing 806, and the wing 806 slides transversely in the transverse groove of the annular reinforcement rib 803.

[0073] A guide plate 807 is fixedly connected to the baffle A701 at equal intervals, a sliding plate 808 is slidably connected to the inner cavity of the guide plate 807, a spring B809 is fixedly connected to the upper and lower end faces of the sliding plate 808, and one end of the spring B809 away from the sliding plate 808 is fixedly connected to the inner cavity wall of the guide plate 807; a circular hole is opened on the sliding plate 808, and the sliding plate 808 is mounted on the porous screen tube 6 through the circular hole.

[0074] in:

[0075] The second component 8 is used to alleviate the impact of extrusion deformation on the pipeline caused by the activated carbon particles settling in the absence of gas support.

[0076] The grid tube body 801 can be arranged in a cross or tic-tac-toe cross pattern.

[0077] The cross-section of the annular reinforcement rib 803 is T-shaped.

[0078] A protective net is provided on the through hole 804 to prevent activated carbon particles from entering the porous sieve tube 6 through the through hole 804 during the non-stripping process.

[0079] The annular reinforcing rib 803 fixed on the high-temperature-resistant sleeve B802 is aligned with the grid nodes of the grid pipe body 801 to form a three-dimensional support frame.

[0080] The annular reinforcing rib 803 and the grid pipe body 801 form a “point-line-surface” combined rigid support system, which improves the anti-deformation ability of the screen pipe.

[0081] The through hole 804 coincides with the steam outlet hole on the porous screen pipe 6.

[0082] The flange of the fin 806 is inclined, which can increase the contact area with the activated carbon particles and reduce the unit area pressure.

[0083] The guide fin 807, the sliding fin 808, and the spring B 809 are used to assist the stable movement of the blocking plate.

[0084] It should be noted that the annular injection pipeline 5 and the porous screen pipe 6 both adopt a double-sleeve structure to reduce thermal stress and structural damage caused by extrusion, thereby prolonging the service life of the pipe body.

[0085] The working principle of all the above embodiments is as follows:

[0086] The working process of the first assembly 7 is as follows:

[0087] During use of the device, first, the annular injection pipeline 5 is protected by the high-temperature-resistant sleeve A 704 with the assistance of the support ring 705. Even if the high-temperature-resistant sleeve A 704 is deformed under pressure, the air layer 706 can provide a moving pressure buffer redundancy to support the protection of the annular injection pipeline 5.

[0088] Further, the high-temperature-resistant sleeve A 704 limited by the blocking plate A 701, the ring seat C 709, and the guide fin 807 will be protected on a fixed basis with the assistance of the damping ring A 702, the ring seat A 703, and the damping ring B 708, the ring seat C 709, to further maintain the fixing effect.

[0089] Specifically, the working process of the damping ring A 702 and the ring seat A 703 is described as follows: when the activated carbon particles press the blocking plate A 701, the damping ring A 702 on the ring seat A 703 will be protected by deformation to avoid the extrusion of the activated carbon sediment on the high-temperature-resistant sleeve A 704 that limits the annular injection pipeline 5, thereby ensuring the relative position of the annular injection pipeline 5 in the desorption tank 1.

[0090] Furthermore, the raised structure of the granular balls 710, unlike the flat structure, can increase the friction between them and the activated carbon particles, maintain the relative stability of the gaps between the particles, and thus slow down the settling speed of the activated carbon particles in the non-blowing stage, thereby indirectly reducing the instantaneous impact force on the high-temperature resistant sleeve A704 of the annular injection pipeline 5; once again, the relative position of the annular injection pipeline 5 in the desorption tank 1 is guaranteed;

[0091] Please refer to the above working process Figures 1 to 5 、 Figure 8 、 Figure 11 .

[0092] The following is the working process of the second component 8:

[0093] During use, in the prior art, the activated carbon particles in the desorption tank 1 will squeeze the porous screen tube 6 during sedimentation. In this design, as the activated carbon particles settle, the activated carbon particles will first contact and exert sedimentation force on the annular reinforcement 803 on the high-temperature resistant sleeve B802. At this time, the force will be distributed locally under the design of the arc surface of the annular reinforcement 803, that is, the contact area is expanded, the pressure is reduced, and the load is avoided from being concentrated on a certain part. At the same time, since it is known that the annular reinforcement 803 fixed on each layer of the high-temperature resistant sleeve B802 is aligned with the grid nodes of the grid tube body 801, they work together to form a three-dimensional support frame. At this time, the load will be further transmitted to the entire grid tube body 801 through the annular reinforcement 803, so that the force is transformed from being borne by a single screen tube to being borne by the entire structure. This is different from the prior art in which the activated carbon particles directly contact the porous screen tube 6, which greatly reduces the risk of the porous screen tube 6 being bent or squeezed and deformed due to long-term exposure to concentrated gravity.

[0094] Furthermore, when the activated carbon particles in the desorption tank 1 squeeze the annular reinforcement rib 803, some of the activated carbon particles act on the inclined surface of the fin 806 sliding inside the annular reinforcement rib 803. The inclined surface design expands the contact area between the fin 806 and the activated carbon particles, so that the particle gravity load and lateral extrusion force are more evenly distributed on the fin 806. This directly reduces deformation, cracking, and other damage to the fin 806 itself caused by long-term concentrated stress, thereby extending the service life of the fin 806.

[0095] It should be noted that in order to ensure that the presence of the porous screen tube 6 does not affect the movement process of the blocking plate A701 in the first component 7, a guide plate 807, a sliding plate 808 and a spring B809 are added for assistance. During the whole process, the sliding plate 808 does not move; and further, the guide plate 807 and the sliding plate 808 in the second component 8 will provide guidance for the blocking plate A701 during its movement, thereby ensuring the stability of the movement of the blocking plate A701.
