Description

Technical Field

[0001] The invention relates to the technical field of activated carbon regeneration, and in particular to an activated carbon desorption regeneration device and a regeneration method. Background Art

[0002] Activated carbon is a specially treated carbon. The organic raw material is heated under air-tight conditions to reduce non-carbon components, and then reacts with gas, the surface is eroded, and a microporous structure is produced. This process is called activation. Since the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point erosion, so the surface of the activated carbon has countless tiny pores. After a period of use, the activated carbon will tend to be saturated due to the adsorption of a large number of impurities, resulting in a decrease in its adsorption capacity and failure to achieve the expected treatment effect. At this time, if it is directly discarded, it will not only cause a waste of resources, but also increase the processing cost and produce secondary pollution. Therefore, the activated carbon is regenerated to restore its adsorption capacity, while reducing the processing cost and reducing environmental pollution, so as to achieve the recycling of resources and sustainable development of the environment.

[0003] The shortcomings of the prior art are that during the adsorption regeneration of the existing granular activated carbon in a rotary furnace, the activated carbon particles collide with the furnace body and adjacent individuals in a high-temperature environment, causing the granular activated carbon to break into powder, which in turn leads to a decrease in the output of the granular activated carbon during regeneration, which has certain shortcomings.

Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

Use; when unloading, the activated carbon powder is fed to the fixed cylinder 14 at the same time through the first feeding pipe 13 and the feeding mechanism; when the fixed cylinder 14 reaches a certain amount, the trigger mechanism cooperates with the driving mechanism to drive the control component to work, and the powder in the rotary kiln body 1 is introduced into the feeding mechanism for storage, and the passage between the feeding mechanism and the fixed cylinder 14 is blocked by the blocking component to stop the feeding; when the material in the fixed cylinder 14 is discharged, the driving mechanism resets and triggers the limit component to move to unlock the driving mechanism, so that the control component is reset, and the first feeding pipe 13 and the feeding mechanism are driven to be opened to feed the fixed cylinder 14 again.

[0047] Furthermore, the feeding mechanism includes a second feeding pipe 31 connected to the distribution box 12, and the bottom end of the second feeding pipe 31 is connected to the storage box 32. The storage box 32 is connected to the first feeding pipe 13 through the third feeding pipe 33. The first feeding pipe 13 and the second feeding pipe 31 are respectively arranged on both sides of the guide seat 23. The powdered activated carbon falling from the filter box 11 can be introduced into the two sides of the guide seat 23 by rotating the guide block 22, and enter the first feeding pipe 13 or the second feeding pipe 31 accordingly. The feeding mechanism is set to avoid the generation of a large amount of powder during the adsorption and regeneration of the activated carbon, which makes the mixing component unable to complete the mixing at one time. At this time, multiple repeated operations are required. During the operation of the mixing component, the activated carbon powder discharged from the rotary furnace body 1 directly enters the storage box 32 through the second feeding pipe 31 for temporary storage.

[0048] Furthermore, the blocking assembly includes a blocking box 41 connected to the third feed pipe 33, and a blocking block 42 is slidably connected in the blocking box 41; one end of the blocking block 42 is fixedly connected to a cross bar 43, one end of the cross bar 43 extends to the outside of the blocking box 41 and is fixedly connected to a baffle 44, and an abutment spring 45 is arranged between the baffle 44 and the blocking box 41, and the elastic force of the abutment spring 45 drives the baffle 44 away from the blocking box 41, and the blocking block 42 is adapted to the inner cavity of the blocking box 41, and when the blocking block 42 moves to the third feed pipe 33 under the action of external force, the third feed pipe 33 can be blocked, so that the activated carbon powder cannot continue to be discharged and the mixing barrel 71 is not fed, but when in a free state, the blocking block 42 does not block the third feed pipe 33, and if there is excess activated carbon powder in the storage box 32, the third feed pipe 33 is fed normally.

The horizontal plate 51 drives the toothed bar 52 to mesh with the gear 53 during the movement. The toothed bar 52 and the gear 53 are arranged on the same plane. When the toothed bar 52 contacts the gear 53 and continues to move, the gear 53 will be driven to drive the rotating rod 21 to rotate, so that the guide block 22 in the material distribution box 12 changes the material guiding direction; An L-shaped push block 54 is fixedly connected to the plate 51, and the L-shaped push block 54 contacts the baffle 44 during its movement. An abutment plate 56 is fixedly connected to one side of the cross plate 51 through a support spring 55. The L-shaped push block 54 moves with the movement of the cross plate 51. When the cross plate 51 moves and the rack 52 arranged thereon contacts the gear 53, the L-shaped push block 54 will also contact the cross plate 51. The abutment plate 56 is fixed on the distribution box 12, and the support spring 55 connected between the two is squeezed by the movement of the cross plate 51, so that the support spring 55 is deformed and accumulates force.

It is in the shape of an inclined surface. When the cross plate 51 moves to squeeze the supporting spring 55, the inclined surface of the bevel gear rod 62 contacts the inclined surface side of the bevel tooth 64. At this time, the bevel gear rod 62 moves up along the inclined surface of the bevel tooth 64. When the bevel gear rod 62 moves in the opposite direction, the plane of the bevel gear rod 62 contacts the plane side of the bevel tooth 64. At this time, the bevel gear rod 62 is stuck in the bevel tooth 64, causing the cross plate 51 to be unable to move. The setting of the limit assembly is mainly to drive the supporting spring 55 to accumulate force to fix the cross plate 51, and only when the limit assembly is released, the supporting spring 55 releases the accumulated force to drive the guide block 22 to rotate again and feed the first feeding pipe 13.

[0051] In the embodiment provided by the present invention, the mixing assembly includes a mixing cylinder 71 that vertically slides in the fixed cylinder 14, and the fixed cylinder 14 is rotatably connected to an active rotating cylinder 72; a mixing rod 73 is vertically slidably connected to the active rotating cylinder 72, and a stirring rod 74 is fixedly connected to the mixing rod 73.

A liquid inlet pipe 79 is also provided on the liquid supply cylinder 75, and the liquid inlet pipe 79 is connected to an external liquid storage device. The liquid stored in the external liquid storage device is mainly to promote the powdered activated carbon powder to become a mud-like state, so as to facilitate the granulator 15 to extrude it into granules. A one-way valve is provided on the liquid supply pipe 78 and the liquid inlet pipe 79. The flow direction of the liquid supply pipe 78 is from the inside of the liquid supply cylinder 75 to the inside of the mixing cylinder 71, and the flow direction of the liquid inlet pipe 79 is from the inside of the external liquid storage device to the liquid supply cylinder 75.

[0052] In the solution further provided by the present invention, the trigger mechanism includes a synchronization rod 81 fixedly connected to the mixing barrel 71, and a trigger plate 82 is fixedly connected to the synchronization rod 81; an elastic telescopic rod 83 is fixedly connected between the trigger plate 82 and the fixed barrel 14, and the elastic force of the elastic telescopic rod 83 drives the trigger plate 82 away from the fixed barrel 14, and a wedge rod 84 is fixedly connected to the trigger plate 82, and an inclined groove 85 is provided on the cross plate 51. The wedge rod 84 contacts the inclined groove 85 during the movement, and the trigger plate 82 is fixedly connected to the piston rod 77. A hole for the vertical movement of the synchronization rod 81 is provided on the mixing barrel 71. When there is activated carbon powder in the mixing barrel 71 in the fixed barrel 14, the synchronization rod 81 will inevitably be pulled downward synchronously, and the synchronization rod 81 moves downward through the trigger plate 82 to the elastic telescopic rod. The retractable rod 83 is stretched, and the elastic retractable rod 83 can also be arranged between the fixed cylinder 14 and the mixing cylinder 71. The trigger plate 82 moves downward to drive the wedge rod 84 to enter the inclined groove 85 in the horizontal plate 51, so as to drive the horizontal plate 51 to move laterally to squeeze and accumulate force on the support spring 55. When the trigger plate 82 moves up and resets, the piston plate 76 pulled by the piston rod 77 moves up synchronously to suck the liquid in the external liquid storage device into the liquid supply cylinder 75, so that the trigger plate 82 moves downward to drive the piston plate 76 to squeeze the liquid in the liquid supply cylinder 75, and the liquid is introduced into the mixing cylinder 71 through the liquid supply pipe 78 for liquid supply and mixing. The amount of liquid squeezed out is related to the weight of the activated carbon powder in the mixing cylinder 71, thereby achieving the effect of automatic liquid supply and automatic proportioning.

[0054] An activated carbon desorption and regeneration method, which is used in the activated carbon desorption and regeneration equipment as described above, comprises the following steps:

[0055] S1: transporting saturated activated carbon to the rotary kiln body 1, and heat-treating the activated carbon filter material by heating, so that the organic matter adsorbed by the activated carbon is carbonized and decomposed at high temperature, and finally becomes gas and escapes, so that the activated carbon is regenerated;

[0056] S2: The regenerated activated carbon is discharged through the discharge port of the rotary furnace body 1 and enters the filter box 11 for separation. The granular activated carbon is directly discharged, and the powdered activated carbon enters the distribution box 12. Under the action of the material control component, it enters the mixing component in the fixed cylinder 14 along the first feeding pipe 13 for mixing. The mixed raw materials enter the granulator 15 to prepare new activated carbon particles.

[0057] S3: When a certain amount of powder raw materials are collected in the mixing component, the mixing component drives the trigger mechanism to move the contact limit component to fix the driving mechanism, so that the driving mechanism self-resets and triggers the material control component to rotate, so that the powder that continues to be fed enters the feeding mechanism for feeding the next mixing of the mixing component.

[0058] Working principle: During operation, the saturated activated carbon particles are transported to the rotary kiln body 1 for adsorption regeneration, and during the process of activated carbon adsorption regeneration, the rotary kiln body 1 is driven to rotate by an external driving source so that the activated carbon inside it can achieve a fully uniform treatment effect, and the treated activated carbon will enter the filter box 11 through the discharge port of the rotary kiln body 1, and the activated carbon after adsorption regeneration can be filtered through the filter box 11, and the granular activated carbon will be discharged from the filter box 11 along the filter screen on the filter box 11, and the associated activated carbon powder will enter the distribution box 12, at this time, the guide block 22 in the distribution box 12 blocks the top of the second feeding pipe 31, and the separated activated carbon powder is discharged along the guide Guided by the guide block 22 and the guide seat 23, it falls into the first feeding pipe 13, and finally enters the mixing box in the fixed box along the first feeding pipe 13. At the same time, the activated carbon powder stored in the storage box 32 will also enter the mixing barrel 71 through the third feeding pipe 33. While feeding, the external driving source is started to drive the active rotating drum 72 to rotate. The rotation of the active rotating drum 72 drives the mixing rod 73 to rotate synchronously, and cooperates with the stirring rod 74 to mix the activated carbon powder in the mixing barrel 71. When the mass in the mixing barrel 71 continues to increase, it will press the mixing barrel 71 to move downward. The mixing barrel 71 moves downward and drives the trigger plate 82 to move downward synchronously through the synchronization rod 81. The trigger plate 82 presses the elastic telescopic rod 83 downward. The trigger plate 82 shrinks, and when the trigger plate 82 moves downward, it also drives the wedge rod 84 and the piston rod 77 to move downward synchronously. The wedge rod 84 moves downward and gradually enters the inclined groove 85 on the cross plate 51, thereby driving the cross plate 51 to move, compressing the support spring 55 to store force, and the downward movement of the trigger plate 82 will also release the supporting force on the connecting plate 66. At this time, the restoring force of the connecting spring 65 connected between the top plate 63 and the support plate 61 drives the helical gear rod 62 to be stuck on the helical teeth 64 on the cross plate 51 and limit it until the toothed bar 52 on the cross plate 51 contacts the gear 53 on the rotating rod 21, and drives the gear 53 to drive the rotating rod 21 to rotate. The rotation of the rotating rod 21 drives the guide block 22 to rotate synchronously, and the rotation of the guide block 22 The passage of a feeding pipe 13 is blocked, so that the falling activated carbon powder enters the storage box 32 through the second feeding passage. At the same time, the L-shaped push block 54 moving with the cross plate 51 contacts the baffle 44 on the cross bar 43 and pushes the baffle 44 to move. The baffle 44 moves through the cross bar 43 to drive the blocking block 42 to block the third feeding pipe 33, so that the third feeding pipe 33 no longer feeds the mixing barrel 71. The downward movement of the piston rod 77 will push the piston plate 76 to squeeze the liquid stored in the liquid supply barrel 75. After being squeezed, the liquid enters the mixing barrel 71 through the liquid supply pipe 78 and merges with the activated carbon powder in the mixing barrel 71. The supply amount of the liquid supply barrel 75 is related to the weight of the powder in the mixing barrel 71.

[0059] At this time, after the activated carbon powder is mixed by adding an equal amount of additives to the mixing barrel 71, the switch valve on the mixing barrel 71 is opened to allow the mixed activated carbon raw materials to enter the granulator 15 for granulation. The granulated activated carbon particles fall onto the circular filter plate 92, and the driving rod 95 drives the toggle plate 96 to rotate, driving the activated carbon particles to move on the circular filter plate 92. During the movement, the activated carbon particles are baked by the temperature of the gas pipe 94, so that the formed activated carbon particles are dried, and then moved to the through groove 93 of the circular filter plate 92 under the action of the toggle plate 96, and fall through the through groove 93 to the collection frame for collection;

[0060] When the mixing barrel 71 discharges materials, its weight decreases. At this time, the restoring force of the elastic telescopic rod 83 drives the mixing barrel 71 to gradually move upward. The upward movement of the mixing barrel 71 drives the trigger plate 82 to move upward through the synchronous rod 81. The upward movement of the trigger plate 82 drives the wedge rod 84 to disengage from the inclined groove 85 on the cross plate 51. At this time, the cross plate 51 is restricted by the helical gear rod 62 and will not move until the trigger plate 82 moves up and contacts the connecting plate 66, and synchronously drives the connecting plate 66 to move upward. The upward movement of the connecting plate 66 drives the top plate 63 to pull the helical gear rod 62 to move upward synchronously. The helical gear rod 62 moves up and separates from the helical teeth 64 on the cross plate 51. At this time, the restoring force of the compressed supporting spring 55 drives the cross plate 51 to reset. During the reset stroke of the cross plate 51, the toothed bar 52 arranged thereon moves in the opposite direction and meshes with the gear 53 on the rotating rod 21, driving the rotating rod 21 to drive the guide block 22 to rotate and reset. At this time, the guide block 22 will block the top of the second feeding pipe 31, and the first feeding pipe 31 The passage between the tube 13 and the distribution box 12 is opened again, and the separated activated carbon can enter the mixing barrel 71 through the first supply pipe 13 again, and the upward movement of the trigger plate 82 will also drive the piston plate 76 to move upward synchronously through the piston rod 77, so that negative pressure is generated in the liquid supply barrel 75, and the liquid in the external liquid storage device is sucked into the liquid supply barrel 75 through the liquid inlet pipe 79 to be used for the next mixing. During the reset movement of the cross plate 51, the L-shaped push block 54 arranged thereon will move with the reset movement of the cross plate 51, and the L-shaped push block 54 is reset to release the abutment against the baffle 44, and the baffle 44 is driven to reset under the action of the abutment spring 45, and the blocking block 42 is synchronously reset by the cross bar 43. The blocking block 42 is reset to make the blocked third supply pipe 33 open synchronously. At this time, the activated carbon powder stored in the storage box 32 enters the mixing barrel 71 through the opened third supply pipe 33 at the same time, and the mixing and granulation operation can be carried out again.
