Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fly ash treatment equipment, in particular to a treatment equipment and method for fly ash of household waste incineration. BACKGROUND

[0002] The fly ash and part of the soluble heavy metal components are contained in the household waste incineration flue gas. The wet spraying is usually used in engineering to wash the flue gas, and the solid waste water formed after spraying is added with a solvent (such as a heavy metal chelating agent, a coagulant / flocculant) to realize solid-liquid separation and standard discharge.

[0003] However, in the prior art, the following efficiency bottlenecks exist: long sedimentation time: the solvent is usually added in the sedimentation tank or the independent settling area, when the concentration and flow of the liquid change, the contact and mixing of the reagent and the suspended particles are insufficient, the floc is generated slowly, the particle size is small, and a long standing time is needed to reach an acceptable clarity and separation degree, which leads to the lengthening of the overall processing rhythm; inefficient holding and transportation: the spray effluent side usually relies on several independent holding containers to sequentially align and receive the waste water. After a single container is filled, it needs to be transported to the sedimentation area for standing and settling. This batch processing mode of "sequential placement-full removal-settling again" easily causes discontinuous liquid reception and waiting time accumulation, thereby further reducing the processing efficiency and increasing the on-site logistics burden and land requirement.

[0004] Therefore, it is urgent to set up a treatment equipment for fly ash of household waste incineration.

[0005] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0006] In order to improve the processing efficiency of fly ash of household waste incineration, the present application provides a treatment equipment and method for fly ash of household waste incineration.

[0007] In a first aspect, the present application provides a treatment equipment for fly ash of household waste incineration, which comprises:

[0008] A treatment frame body having a first end and a second end arranged oppositely;

[0009] A spraying unit arranged at the first end for spraying fly ash-containing flue gas to generate waste water, the spraying unit having a liquid outlet side;

[0010] An accepting unit arranged at the liquid outlet side, the accepting unit comprising an accepting support, a driving assembly, and a plurality of accepting barrels arranged along the circumference of the accepting support, the plurality of accepting barrels being rotatably mounted on the accepting support by the driving assembly;

[0011] The driving assembly is capable of working in a first state and a second state.

[0012] In the first state, the driving assembly drives the plurality of receiving tubes to move along the receiving support, so that different receiving tubes are sequentially located at the receiving position of the liquid outlet side.

[0013] In the second state, the driving assembly drives the plurality of receiving tubes to rotate around their own axes.

[0014] The adding unit is configured to add a solvent into the receiving tube to promote the solid-liquid separation of the wastewater.

[0015] By using the above technical solution, the flue gas containing fly ash is sprayed at the first end of the treatment frame through the spraying unit, and the generated wastewater is discharged from the liquid outlet side of the spraying unit and received by the receiving unit arranged at the liquid outlet side. The receiving unit includes a receiving support, a driving assembly, and a plurality of receiving tubes arranged circumferentially along the receiving support. The driving assembly first works in a first state to drive the plurality of receiving tubes to move along the receiving support, so that different receiving tubes are sequentially located at the receiving position of the liquid outlet side to complete the receiving of the incoming liquid. Then, the driving assembly is switched to a second state to make the plurality of receiving tubes rotate around their own axes, and at the same time, the adding unit in communication with the receiving tube adds a solvent into the tube to promote the solid-liquid separation of the wastewater.

[0016] By arranging the receiving unit at the liquid outlet side of the spraying unit and using the circumferential arrangement of the plurality of receiving tubes in cooperation with the driving assembly, the receiving, dosing, and separation are alternately performed on different receiving tubes, avoiding the stop caused by the one-by-one alignment and transportation of containers, and realizing continuous treatment. With the communication between the adding unit and the receiving tube and the rotation mixing in the tube, the contact between the medicament and the incoming liquid is strengthened, the solid-liquid separation is accelerated, and the waiting time is shortened.

[0017] Optionally, the driving assembly includes:

[0018] A driving gear ring is rotationally connected to the receiving support.

[0019] A plurality of driven wheels are arranged at intervals along the circumference of the driving gear ring, wherein each driven wheel is in mesh with the driving gear ring, and the receiving tube is connected to the driven wheel.

[0020] A driving wheel is rotationally connected to the gap between the plurality of driven wheels and is in mesh with each driven wheel.

[0021] A first power member is configured to rotate the driving wheel.

[0022] A second power member is configured to rotate the plurality of driven wheels.

[0023] By adopting the technical scheme, in the first state, the second power member is enabled to drive the multiple sets of driven wheels to rotate, and the driven wheels are engaged with the gear of the driving gear ring to roll relative to each other, thereby driving the receiving cylinders to move along the receiving support in the circumferential direction, so that the different receiving cylinders reach the receiving positions on the liquid outlet side of the spraying unit in turn; in the second state, the first power member is enabled to drive the driving wheel to rotate, the driving wheel is engaged with each driven wheel and outputs a rotation torque to the driven wheel, so that the multiple receiving cylinders connected to the driven wheels rotate around their own axes to complete the mixing and separation treatment in the receiving cylinders, and then the first state is switched back to perform the next station, thereby realizing the cyclic and continuous operation of the receiving-rotation treatment.

[0024] The above structure can realize the equal pitch and continuous circumferential rotation of the receiving cylinders by the second power member; meanwhile, the driving wheel arranged in the gap and engaged with each driven wheel can be driven by the first power member to realize the synchronous or independent rotation of all the receiving cylinders, thereby combining the functions of "overall rotation" and "rotation treatment", reducing the number of components and the maintenance difficulty; meanwhile, the driving wheel is arranged in the gap between the driven wheels to save the radial space, so that the receiving unit structure is more compact and the channel is more unobstructed, and the parallel station of multiple receiving cylinders and the small land layout can be realized.

[0025] Optionally, the first power member comprises:

[0026] a first rotating shaft, which is rotationally connected to the receiving support, and the axial direction of the first rotating shaft is the same as the axial direction of the receiving cylinder;

[0027] a first motor, which is configured to drive the first rotating shaft to rotate.

[0028] By adopting the above technical scheme, the first power member is composed of the first rotating shaft and the first motor, the first rotating shaft is rotationally mounted on the receiving support, and the axial direction of the first rotating shaft is the same as the axial direction of the receiving cylinder; when the driving assembly is switched to the rotation condition, the first motor drives the first rotating shaft to rotate, the first rotating shaft outputs power to the driving wheel in transmission connection therewith, the driving wheel is engaged with the circumferentially distributed driven wheels one by one and drives them to rotate, thereby enabling the receiving cylinders connected to the driven wheels to rotate around their own axes, respectively, to complete the mixing and solid-liquid separation treatment in the cylinders after adding the medicine.

[0029] By making the axial direction of the first rotating shaft consistent with the axial direction of the receiving cylinder, the power transmission link is in the same direction as the cylinder rotation axis, the intermediate transmission and additional bias are reduced, the transmission efficiency is high, the vibration is small, and the positioning is stable; the first motor drives the driving wheel through the first rotating shaft to realize the centralized driving and synchronization of the rotation of the multiple receiving cylinders, so that the structure is more compact, the components are fewer, and the maintenance is more convenient, which is beneficial to shorten the separation interval, improve the overall processing stability and reliability.

[0030] Optionally, the second power component comprises:

[0031] A second rotating shaft, one end of which is rotatably connected to the receiving support, and the axial direction of the second rotating shaft is the same as that of the receiving cylinder;

[0032] A power support connected to the other end of the second rotating shaft, wherein the power support has a plurality of connecting portions corresponding to the driven wheels;

[0033] A second motor for driving the second rotating shaft to rotate.

[0034] By adopting the above technical scheme, the second power component is composed of a second rotating shaft, a power support and a second motor. One end of the second rotating shaft is rotatably installed on the receiving support, and the axial direction of the second rotating shaft is the same as that of the receiving cylinder. The other end of the second rotating shaft is fixedly connected to the power support. The power support is provided with a plurality of connecting portions corresponding to the driven wheels, and is connected to the driven wheels through the connecting portions. In operation, the second motor drives the second rotating shaft to rotate, thereby driving the power support to rotate circumferentially as a whole. The power support transmits the rotating force to the corresponding driven wheels through the connecting portions. Since the driven wheels are in meshing engagement with the driving gear ring, the rotation of the power support enables the receiving cylinders to move circumferentially along the receiving support, so that different receiving cylinders reach the receiving position on the liquid outlet side of the spraying unit in sequence, thereby enabling the receiving cylinders to move to the liquid outlet side for uninterrupted receiving task, and creating a rhythm and a working position condition for the subsequent rotation of the receiving cylinders (driven by the first power component to drive the driving wheel).

[0035] The second rotating shaft is coaxially arranged with the receiving cylinder, so that the rotating transmission chain is straight, rigid and has small eccentric load. The power support centered on the second rotating shaft synchronously drives a plurality of receiving cylinders / driven wheels through a plurality of connecting portions, and in cooperation with the direct meshing engagement between the driven wheels and the driving gear ring, a circumferential displacement effect with high positioning accuracy and good repeatability can be obtained, thereby reducing backlash and slipping. The integrated scheme of motor-rotating shaft-support has few components, occupies small space, and is convenient for wiring and maintenance, which is conducive to arranging more receiving cylinders in a compact structure, realizing continuous rotation and replacement, thereby reducing the demand for manual positioning and carrying of containers, and improving the processing rhythm, operation stability and reliability of the whole machine.

[0041] Optionally, the blocking member comprises:

[0044] By adopting the technical scheme, the blocking member comprises the blocking plate for opening and closing the channel and the driving source. During operation, the receiving cylinder is in a sedimentation stage, the driving source drives the blocking plate to move axially to the sealing position to separate the first cylinder segment and the second cylinder segment; when the receiving cylinder is driven to a predetermined working position to enter a transfer stage (to clean the solid on the blocking plate), the driving source drives the blocking plate in the first direction to drive the blocking plate to move to the position for cleaning the solid, so as to facilitate subsequent cleaning of the solid on the blocking plate.

[0045] Optionally, the driving source comprises:

[0051] By adopting the technical scheme, the device is initially in a connected state, a driving motor drives a driving screw rod located in the second cylinder section and axially perpendicular to the first cylinder section to rotate, because the distance between the top surface of the first sliding block and the bottom wall of the second cylinder section is greater than the distance between the top surface of the second sliding block, the blocking plate arranged on the side of the first sliding block and the second sliding block away from the bottom wall is lifted by the first sliding block when the first sliding block approaches the second sliding block, and is lifted to a sealing position with the continuous rotation of the screw rod, so that the first cylinder section and the second cylinder section are sealed; when solid is deposited on the blocking plate and the solid on the blocking plate needs to be removed, the driving motor reversely rotates, the first sliding block and the second sliding block move together, and the blocking plate is driven to a subsequent cleaning position under the action of the first sliding block and the second sliding block.

[0058] The extraction support is arranged on one side of the receiving support and the extraction pipe is coaxially lifted, so that the liquid in the cylinder can be extracted in situ without changing the circumferential arrangement of the receiving cylinder; the lifting assembly controls the insertion and extraction actions, and cooperates with the communication suction of the extraction pump to quickly remove the liquid in the cylinder, release the volume, shorten the waiting time and improve the continuous processing rhythm; the extraction unit is an independent module and can be flexibly switched between multiple receiving cylinders, occupies small space, is easy to modify and maintain, reduces manual transportation and secondary pollution risk, and improves the processing efficiency, continuity and operation safety of the system as a whole.

[0088] During operation, the flue gas containing fly ash enters the spray unit 2 of the first end 11, forms a thin layer of solid waste-containing wastewater on the liquid outlet side 21 after spraying and demisting, and flows by gravity into the receiving position below;the drive assembly 32 is in the first state, drives the plurality of receiving tubes 33 arranged along the circumference of the receiving support 31 to revolve in a rhythm, the receiving tubes 33 are sequentially positioned at the receiving position, and then the adding unit 7 injects a preset amount of solvent into the receiving tubes 33 to mix with the received wastewater;the drive assembly 32 is switched to the second state, the receiving position and the plurality of receiving tubes 33 after the receiving position rotate around their own axes, accelerate flocculation and solid-liquid separation;when the separation time of a certain receiving tube 33 reaches a set threshold, the drive assembly 32 is switched to the first state again, the receiving tube 33 is unlocked and revolves to other positions to perform subsequent processes.In the subsequent processes, the substances in the receiving tubes 33 after solid-liquid separation are processed, and the processed receiving tubes 33 are again positioned at the receiving position to participate in the next cycle, so as to realize the quasi-continuous processing process of the plurality of receiving tubes 33 in rotation.

[0089] It should be noted that, in the embodiments of the present application, the function of the spray unit 2 is to spray the flue gas containing fly ash to generate wastewater, which is well known to those skilled in the art, and the structure is not described in detail.

[0090] As an example, the receiving cylinder 33 comprises a first cylinder segment 331 and a second cylinder segment 332 arranged in sequence along the vertical direction; the first cylinder segment 331 and the second cylinder segment 332 are provided with a blocking piece 34; the receiving cylinder 33 has a sedimentation state; in the sedimentation state, the blocking piece 34 is closed to block the first cylinder segment 331 and the second cylinder segment 332 from each other and not communicate with each other, so as to separate the solid and liquid in the receiving cylinder 33.

[0091] In this example, after the receiving cylinder 33 moves to the receiving position, the blocking piece 34 remains closed to block the first cylinder segment 331 and the second cylinder segment 332 from each other; the solid-containing wastewater enters the first cylinder segment 331 from top to bottom, and at this time the receiving cylinder 33 is stationary or rotates at low speed under the action of the driving assembly 32 to realize the solid-liquid separation of the wastewater; further, due to the closing of the blocking piece 34, the sediment is limited in the first cylinder segment 331 and does not communicate with the second cylinder segment 332, until the subsequent working condition is switched to the first cylinder segment 331 and the second cylinder segment 332 to communicate and unload the solid.

[0092] Further, the blocking piece 34 comprises a blocking plate 341 and a driving source 342; the driving source 342 is connected with the blocking plate 341 and is used to drive the blocking plate 341 to move along the axial direction of the first cylinder segment 331 to block or open the first cylinder segment 331 and the second cylinder segment 332; at the same time, the driving source 342 is also used to drive the blocking plate 341 to move along a first direction, wherein the axial direction of the first cylinder segment 331 is perpendicular to the first direction.

[0093] Specifically, in the sedimentation stage, the driving source 342 drives the blocking plate 341 to move upward along the cylinder axis to the closed position, the first cylinder segment 331 and the second cylinder segment 332 are blocked, and the solid is deposited and accumulated on the blocking plate 341; when the receiving cylinder 33 moves to the predetermined transfer position (the solid-liquid separation of the solid wastewater in the receiving cylinder 33 is completed), the driving source 342 drives the blocking plate 341 to move downward to release the sealing pre-pressing (the solid is deposited on the blocking plate 341), and then the driving source 342 drives the blocking plate 341 to move along the first direction perpendicular to the cylinder axis, so that the solid accumulated on the blocking plate 341 moves to the second cylinder segment 332 to facilitate cleaning.

[0094] In some embodiments, the driving source 342 comprises a driving screw 3421, a first sliding block 3422, a second sliding block 3423 and a driving motor 3424; the driving screw 3421 is rotationally connected in the second cylinder segment 332, and the axial direction of the driving screw 3421 is perpendicular to the axial direction of the first cylinder segment 331; the first sliding block 3422 and the second sliding block 3423 are arranged on the driving screw 3421 (in this application, the driving screw 3421 is a one-way threaded rod); the blocking plate 341 is arranged on the side of the first sliding block 3422 and the second sliding block 3423 away from the bottom wall of the second cylinder segment 332; the driving motor 3424 is used to drive the driving screw 3421 to rotate; wherein the distance between the top surface of the first sliding block 3422 and the bottom wall of the second cylinder segment 332 is greater than the distance between the top surface of the second sliding block 3423 and the bottom wall of the second cylinder segment 332, so that when the first sliding block 3422 is close to the second sliding block 3423, the blocking plate 341 is lifted to seal the first cylinder segment 331 and the second cylinder segment 332. The driving motor 3424 drives the driving screw 3421 in the second cylinder segment 332 to rotate, which is perpendicular to the axial direction of the first cylinder segment 331; at this time, the first sliding block 3422 and the second sliding block 3423 move towards the communication between the first cylinder segment 331 and the second cylinder segment 332; because the driving screw 3421 is not provided with a threaded section at the corresponding position of the communication between the first cylinder segment 331 and the second cylinder segment 332 (this feature is not marked in the drawings of this application), at this time, the second sliding block 3423 will stop moving, and the first sliding block 3422 will move below the blocking plate 341; the first sliding block 3422 moves towards the second sliding block 3423; because the distance between the top surface of the first sliding block 3422 and the bottom wall of the second cylinder segment 332 is greater than the distance between the top surface of the second sliding block 3423 and the bottom wall of the second cylinder segment 332, and the side of the blocking plate 341 close to the bottom wall of the second cylinder segment 332 has a protruding portion (this feature is not specifically marked in this application), when the first sliding block 3422 contacts the protruding portion, the blocking plate 341 is lifted (one end of the blocking plate 341 is rotationally connected with the second sliding block 3423, so that the blocking plate 341 tends to move upward), thereby realizing the sealing of the first cylinder segment 331 and the second cylinder segment 332.

[0095] Similarly, when it is necessary to remove the solids on the blocking plate 341, the driving motor 3424 drives the driving screw 3421 to rotate reversely. Since the second sliding block 3423 is located in the portion without thread, the second sliding block 3423 will not move with the driving screw 3421 in the initial stage, while the first sliding block 3422 will move with the rotation of the driving screw 3421. At this time, the first sliding block 3422 is away from the second sliding block 3423, and the first sliding block 3422 is gradually separated from the protruding portion. At this time, the blocking plate 341 moves downward, and the first cylinder segment 331 and the second cylinder segment 332 are in communication. Since the connecting piece (not specifically marked in the drawings of the present application) is arranged between the first sliding block 3422 and the second sliding block 3423, the first sliding block 3422 will also drive the second sliding block 3423 to move while moving. The movement of the first sliding block 3422 and the second sliding block 3423 achieves the purpose of moving the blocking plate 341 to the outlet 3321 of the second cylinder segment 332, so as to facilitate the subsequent removal of the solids on the blocking plate 341.

[0096] As an example, the driving source 342 further comprises a guide 3425; the guide 3425 comprises a first guide column 34251 and a second guide column 34252; the first guide column 34251 is arranged on the second sliding block 3423; the second guide column 34252 is arranged on the side of the blocking plate 341 close to the second sliding block 3423; wherein the second guide column 34252 has a guide hole 34253 matched with the first guide column 34251, so as to facilitate the upward or downward guidance of the blocking plate 341.

[0097] In some embodiments of the present disclosure, the processing device further comprises an adsorption unit 5; the second cylinder segment 332 has an outlet 3321; the blocking plate 341 is movable to the outlet 3321 by the driving source 342, and the adsorption unit 5 is arranged at the outlet 3321 and used for adsorbing and collecting the solid waste on the blocking plate 341. When the sedimentation stage is over and it is necessary to clean the solids on the blocking plate 341, the driving source 342 first lowers the blocking plate 341, and the first cylinder segment 331 communicates with the second cylinder segment 332; the driving motor 3424 drives the driving screw 3421 to rotate, so that the first sliding block 3422 and the second sliding block 3423 move in the first direction perpendicular to the axis of the receiving cylinder 33. The movement of the first sliding block 3422 and the second sliding block 3423 drives the blocking plate 341 to laterally translate to the outlet 3321 of the second cylinder segment 332 and align with the reference of the outlet 3321. The adsorption unit 5 at the outlet 3321 quickly adsorbs the solid waste attached to the blocking plate 341 and transports it to the collection container through the pipeline.

[0098] It should be noted that the adsorption unit 5 is used to adsorb and process the solids on the blocking plate 341 by generating negative pressure; this structure is well known to those skilled in the art, and thus will not be described here.

[0099] Meanwhile, it should be noted that in the embodiments of the present disclosure, the adsorption unit 5 can be lifted to better remove the solids on the blocking plate 341.

Meanwhile, the lifting structure can be provided so that the blocking plate 341 can remove the solids thereon without extending out of the outlet 3321 of the second cylinder segment 332.
