Description

Technical Field

[0001] This invention relates to the field of pyrolysis equipment technology, specifically to a photothermal energy storage multi-wave field time-series coupled low-temperature pyrolysis gasification device and method. Background Technology

[0002] Low-temperature pyrolysis gasification of solid waste is one of the core technologies for the harmless, reduced-volume, and resource-based disposal of solid waste at present. Compared with high-temperature incineration, it has significant advantages such as lower reaction temperature, less dioxin generation, less flue gas pollution, and recoverable pyrolysis gas resources. It is widely used in resource-based treatment scenarios for various types of waste, including industrial solid waste, municipal solid waste, and biomass solid waste. With the advancement of the "dual-carbon" policy and the continuous upgrading of solid waste disposal standards, the industry has put forward higher requirements for the continuous operation stability, residue cleanliness, automation level, and energy utilization efficiency of low-temperature pyrolysis units. Existing low-temperature pyrolysis gasification units have significant technical defects in practical applications: the components of various solid wastes to be treated are complex, generally mixed with a large amount of non-pyrolyzable particulate matter such as metals, sand, glass, and inorganic ash. These substances cannot undergo pyrolysis gasification reactions in the low-temperature pyrolysis environment and will continue to remain in the pyrolysis reaction chamber. At present, traditional pyrolysis equipment only relies on simple fixed support screens or fixed grates to carry solid waste raw materials, and does not have dynamic separation of non-pyrolyzable particles and pyrolyzable solid waste, automatic slag discharge structure, and process measures during the pyrolysis process. In the process of cryogenic pyrolysis of solid waste, pyrolyzable organic matter is continuously consumed through pyrolysis and gasification, while non-pyrolyzable solid impurities are easily stuck and accumulate in the gaps between the grate supports and on the surface of the load-bearing structure, unable to fall off and be discharged on their own. On the one hand, the accumulated non-pyrolyzable particles will cover the heated surface of the solid waste raw material, hindering the conduction of light and heat energy, resulting in uneven temperature field distribution inside the furnace, significantly reducing the efficiency of solid waste pyrolysis and gasification, and causing problems such as insufficient pyrolysis of raw materials and low resource utilization. On the other hand, the hard non-pyrolyzable impurities that have been stuck for a long time are prone to clogging the gaps between the grate, causing slag and scale buildup in the equipment, leading to malfunctions such as local overheating of the furnace body, equipment jamming, and operational malfunctions, seriously affecting the continuous and stable operation of the pyrolysis unit and significantly shortening the service life of the equipment. To address these technical problems, we propose a photothermal energy storage multi-wave field time-sequential coupling cryogenic pyrolysis and gasification device and its method. Summary of the Invention

[0003] This invention provides the following technical solution: a photothermal energy storage multi-wave field time-series coupled low-temperature pyrolysis gasification device, comprising: The reactor body and the slag discharge mechanism fixedly installed at the bottom of the reactor body. The slag discharge mechanism is used to support the solid waste materials required for the photothermal energy storage multi-wave field time-sequential coupling low temperature pyrolysis gasification. The slag discharge mechanism is rotatable relative to the reactor body, so as to discharge non-pyrolyzable particles to the bottom of the slag discharge mechanism. A photothermal plate is fixedly installed on the side of the reactor body. The drive mechanism is located on one side of the slag discharge mechanism. It is used to drive the mechanism to swing and discharge non-pyrolytic particles. The drive mechanism can move upward relative to the slag discharge mechanism, thereby driving the slag discharge mechanism to rotate as a whole, thereby dumping the non-pyrolytic particles accumulated above the slag discharge mechanism.

[0004] As a preferred embodiment of the present invention, the slag discharge mechanism includes an ash collection chamber fixedly disposed at the bottom of the reactor body, and a plurality of supporting rollers rotatably installed inside the ash collection chamber. The bottom of the ash collection chamber is provided with an openable sealing door, and in the initial state, the sealing door seals the bottom of the ash collection chamber. The supporting rollers are evenly distributed along the width direction of the ash collection chamber, and a plurality of equally distributed supporting teeth are fixedly disposed on the outer ring surface of the supporting rollers. The supporting teeth on the outer ring surface of two adjacent supporting rollers are staggered, and the plurality of supporting teeth form a support structure for the solid waste material.

[0005] As a preferred embodiment of the present invention, a transmission sprocket is fixedly provided on the outer ring surface of several supporting rollers near their first ends, and a synchronous chain capable of uniformly driving all transmission sprockets is assembled at the first ends of several supporting rollers. The synchronous chain meshes with each transmission sprocket to form a transmission structure in which multiple sets of transmission sprockets are synchronously linked.

[0006] In a preferred embodiment of the present invention, at least one of the supporting rollers is fixedly provided with an eccentric counterweight at its first end. In the initial state, the center of gravity of the eccentric counterweight is downward, thereby keeping the supporting tooth block horizontal.

[0007] As a preferred embodiment of the present invention, the driving mechanism includes a deflection block fixedly installed at the second end of the supporting roller, and a lifting mounting frame disposed on the side of the reactor body near the deflection block. The lifting mounting frame is movable along the height direction of the reactor body. In the initial state, the deflection block faces downward. A driven sprocket is rotatably disposed at the first end of the lifting mounting frame, and a driving sprocket is rotatably disposed at the second end of the lifting mounting frame. A power chain is sleeved around the driven sprocket and the driving sprocket. The power chain is located on one side of the deflection block, and a plurality of sheet metal bending blocks are fixedly disposed on the power chain. The positions of the sheet metal bending blocks are adapted to the positions of the deflection block. A reduction motor is fixedly disposed on the side of the lifting mounting frame away from the driving sprocket, and the driving sprocket is fixedly mounted on the output shaft of the reduction motor.

[0008] As a preferred embodiment of the present invention, a clearance groove is provided on one side of the deflection block near the power chain. The depth of the clearance groove is greater than the length of the bent portion of the sheet metal bending block, and the width of the clearance groove at the top and bottom is greater than the sheet metal thickness of the sheet metal bending block.

[0009] As a preferred embodiment of the present invention, a discharge sprocket is fixedly provided on the outer ring surface of several supporting rollers near their second ends. The specifications of the discharge sprocket are compatible with the specifications of the power chain. During initial installation, the sheet metal bending block is located at the bottom of the discharge sprocket, and the sheet metal bending block does not mesh with the discharge sprocket.

[0010] As a preferred embodiment of the present invention, at least one lifting drive cylinder is fixedly installed on the side wall of the reactor body near the lifting mounting frame. The piston rod of the lifting drive cylinder is arranged upward, and the top end of the piston rod is fixedly connected to the bottom of the lifting mounting frame via a floating joint, thereby pushing the lifting mounting frame to move upward.

[0011] As a preferred embodiment of the present invention, a support plate is fixedly provided on one side of the lifting mounting frame near the power chain. The top surface of the support plate contacts the bottom surface of the upper part of the power chain segment, and the support plate provides support for the upper part of the power chain segment.

[0012] A method for using a photothermal energy storage multi-wave field time-series coupled cryogenic pyrolysis gasification device includes the following steps: S1. The solid waste material is pyrolyzed at low temperature on the upper part of the support structure composed of several support blocks. During the low temperature pyrolysis of the solid waste material, some fine particles that cannot be pyrolyzed will fall naturally from the gap between adjacent support blocks to the bottom of the ash collection chamber for collection. S2. During the pyrolysis and gasification process, the output shaft of the geared motor drives the drive sprocket to rotate, which in turn drives the driven sprocket to rotate synchronously through the power chain. During the rotation, the sheet metal bending blocks on the power chain pass through the position of the deflection blocks in turn, thereby pushing the side of the deflection blocks and driving the corresponding connected support rollers to deflect at a small angle. This causes the support rollers to drive the support teeth blocks fixed on their outer ring surface to deflect synchronously, causing the non-pyrolyzable particles stuck in the gap between adjacent support teeth blocks to lose support and fall off. S3. After use, the piston rod of the lifting drive cylinder pushes the lifting mounting frame upward, causing the driven sprocket, drive sprocket, power chain, and sheet metal bending blocks to move upward together. This causes the bent part of each sheet metal bending block to engage with the clearance groove on the side of the corresponding deflection block. At the same time, the sheet metal bending blocks will move upward to the position where they mesh with the unloading sprocket. At this time, the reduction motor is started to drive the power chain to continue rotating. This will cause all the deflection blocks and the corresponding connected support rollers to rotate synchronously through the sheet metal bending blocks. At this time, the support rollers will cause all the support teeth to flip as a whole, tilting the non-degradable particles that were originally supported on the top of the support teeth downward. The non-degradable particles fall into the ash collection chamber below through the gap between adjacent support teeth. Finally, the sealing door at the bottom of the ash collection chamber can be opened to discharge all the non-degradable particles.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up a support roller that can be synchronously deflected at a small angle and staggered support teeth, can drive the support roller to continuously swing at a small angle during the pyrolysis and gasification operation. This dynamically shakes off the non-pyrolyzable particles stuck in the gaps between the support teeth, maintains a stable and efficient pyrolysis and gasification reaction efficiency, reduces the frequency of equipment shutdown for cleaning, and ensures continuous production operations.

[0014] 2. This invention, through a liftable and movable drive mechanism in conjunction with the unloading sprocket at the end of the supporting rollers, can drive all supporting rollers to rotate synchronously after the operation is completed, and dump out the remaining non-pyrolytic particles and residual materials on the supporting blocks in one go. Compared with the traditional fixed grate structure, the slag discharge is more thorough, and there is no need for manual entry into the furnace to clean the remaining non-pyrolytic particles, which reduces the difficulty and workload of equipment maintenance.

[0015] 3. The present invention adopts a horizontal support structure with multiple support rollers arranged in an alternating manner to support and fix the material, which avoids the problem of uneven distribution of material at the edge and sparse material in the center caused by the gravity rolling of material in the traditional conical furnace body. It can ensure that the material distribution in the furnace is uniform, making the combustion and pyrolysis reaction more uniform and stable, and improving the overall treatment effect of pyrolysis and gasification.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 7 The technical solution provided by the present invention specifically includes the following embodiments: A solar thermal energy storage multi-wave field time-coupling low-temperature pyrolysis gasification device includes a reactor body 100, a slag discharge mechanism 200, and a drive mechanism 300. The slag discharge mechanism 200 is used to support the solid waste material required for solar thermal energy storage multi-wave field time-coupling low-temperature pyrolysis gasification. The slag discharge mechanism 200 is rotatable relative to the reactor body 100, thereby discharging non-pyrolyzable particles to the bottom of the slag discharge mechanism 200. The drive mechanism 300 is disposed on one side of the slag discharge mechanism 200 and is used to drive the mechanism 200 to swing and discharge non-pyrolyzable particles. The drive mechanism 300 is also movable upward relative to the slag discharge mechanism 200, thereby driving the slag discharge mechanism 200 to rotate as a whole, thereby dumping the non-pyrolyzable particles accumulated above the slag discharge mechanism 200. A solar thermal plate 400 is fixedly disposed on the side of the reactor body 100. The solar thermal plate 400 is used to convert solar energy into heat energy and conduct it to the interior of the reactor body 100, providing a part of the heat source for the low-temperature pyrolysis of solid waste.

[0020] For further details, please refer to [link / reference]. Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown: The slag discharge mechanism 200 includes an ash collection chamber 201 fixedly disposed at the bottom of the reactor body 100, and a plurality of supporting rollers 202 rotatably installed inside the ash collection chamber 201. The bottom of the ash collection chamber 201 is provided with an openable sealing door, which initially seals the bottom of the ash collection chamber 201. The supporting rollers 202 are evenly distributed along the width direction of the ash collection chamber 201. A plurality of evenly distributed supporting teeth 203 are fixedly disposed on the outer ring surface of the supporting rollers 202, with the supporting teeth 203 on the outer ring surfaces of adjacent supporting rollers 202 being staggered. 3. A support structure for solid waste materials is formed. Each of the several support rollers 202 has a transmission sprocket 204 fixedly installed on the outer ring surface near its first end. The first ends of the several support rollers 202 are equipped with a synchronous chain 205 that can uniformly drive all the transmission sprockets 204. The synchronous chain 205 meshes with each transmission sprocket 204 to form a transmission structure in which multiple sets of transmission sprockets 204 are synchronously linked. At least one of the support rollers 202 has an eccentric counterweight 206 fixedly installed at its first end. In the initial state, the center of gravity of the eccentric counterweight 206 is downward, so that the support tooth block 203 remains horizontal.

[0021] Specifically, the solid waste material undergoes low-temperature pyrolysis at the upper end of a support structure composed of several support teeth 203. During the low-temperature pyrolysis process, some fine, non-pyrolyzable particles will naturally fall from the gaps between adjacent support teeth 203 to the bottom of the ash collection chamber 201 for collection. Under the downward force of the eccentric counterweight 206, the support rollers 202 and support teeth 203 connected to the eccentric counterweight 206 always maintain a horizontal support state and will not deflect autonomously under the action of gravity, thus ensuring the support stability of the solid waste material during the pyrolysis process. At the same time, the synchronous chain 205 meshes with several transmission sprockets 204 simultaneously, thereby ensuring that all support rollers 202 and support teeth 203 will not deflect autonomously under the action of gravity, thus ensuring the support stability of the solid waste material during the pyrolysis process.

[0022] For further details, please refer to [link / reference]. Figure 3 , Figure 4 , Figure 7 As shown: The drive mechanism 300 includes a deflection block 301 fixedly mounted on the second end of the support roller 202, and a lifting mounting frame 302 disposed on the side of the reactor body 100 near the deflection block 301. The lifting mounting frame 302 is movable along the height direction of the reactor body 100. In the initial state, the deflection block 301 faces downward. A driven sprocket 303 is rotatably disposed on the first end of the lifting mounting frame 302, and a driving sprocket 304 is rotatably disposed on the second end of the lifting mounting frame 302. A power chain 305 is fitted around the sprocket 303 and the drive sprocket 304. The power chain 305 is located on one side of the deflection block 301. Several sheet metal bending blocks 306 are fixedly installed on the power chain 305. The positions of the sheet metal bending blocks 306 are adapted to the positions of the deflection blocks 301. A reduction motor 307 is fixedly installed on the side of the lifting mounting frame 302 away from the drive sprocket 304. The drive sprocket 304 is fixedly mounted on the output shaft of the reduction motor 307.

[0023] Specifically, the solid waste material undergoes low-temperature pyrolysis at the top of a support structure composed of several support blocks 203. During the low-temperature pyrolysis process, some non-pyrolyzable particles will naturally fall from the gaps between adjacent support blocks 203 to the bottom of the ash collection chamber 201 for collection. However, some non-pyrolyzable particles remain on the top of the support blocks 203 and do not fall naturally. Therefore, during the pyrolysis process, the reduction motor 307 needs to be activated. The output shaft of the reduction motor 307 drives the drive sprocket 304 to rotate slowly and uniformly. The drive sprocket 304 drives the power chain 3 sleeved on the outside. 05 rotates cyclically, and the sheet metal bending block 306 is driven by the power chain 305 to move cyclically along the rotation trajectory of the power chain 305. During the movement of the sheet metal bending block 306, its own bent part will contact the side of the deflection block 301, thereby generating a lateral push on the side of the deflection block 301, driving the corresponding connected support roller 202 to deflect at a small angle, so that the support roller 202 drives the support tooth block 203 fixed on its outer ring surface to deflect synchronously, causing the non-degradable particles stuck in the gap between adjacent support tooth blocks 203 to lose support and fall off, completing the process. The automatic ash removal operation eliminates the need for manual ash cleaning, reducing labor maintenance costs. Furthermore, since the first ends of several support rollers 202 are simultaneously meshed with multiple transmission sprockets 204 via a synchronous chain 205, when any one support roller 202 deflects, the remaining support rollers 202 will deflect synchronously, ensuring that all support blocks 203 can move synchronously, achieving stable dropping of all non-pyrolytic particles. During the deflection of the support rollers 202, the eccentric counterweight 206 also deflects at a certain angle, causing the center of gravity of the eccentric counterweight 206 to shift away from its normal position. The bottom of the axis of the support roller 202 is supported. As the sheet metal bending block 306 continues to move, the sheet metal bending block 306 eventually finishes pushing the side of the deflection block 301. At this time, the eccentric counterweight block 206 resets under its own gravity, driving the entire support roller 202 to deflect in the opposite direction and reset, waiting for the next side push of the sheet metal bending block 306. This cycle can realize the continuous reciprocating small-angle swing of the support roller 202 and the support tooth block 203, so that the stuck non-degradable particles are loosened and fall off, and the dust removal operation will not affect the continuous operation of the entire device.

[0024] For further details, please refer to [link / reference]. Figure 3 , Figure 7 As shown: The deflector block 301 has a clearance groove 308 on one side near the drive chain 305. The depth of the clearance groove 308 is greater than the length of the bent portion of the sheet metal bending block 306, and the vertical width of the clearance groove 308 is greater than the sheet metal thickness of the sheet metal bending block 306. A discharge sprocket 309 is fixedly mounted on the outer ring surface of several support rollers 202 near their second ends. The specifications of the discharge sprocket 309 are compatible with the specifications of the drive chain 305. Initially, the sheet metal bending block 306 is located at the bottom of the discharge sprocket 309, and the sheet metal bending block 306 and the discharge sprocket 309 are not engaged. At least one lifting drive cylinder 3010 is fixedly installed on the side wall of the reactor body 100 near the lifting mounting frame 302. The piston rod of the lifting drive cylinder 3010 is arranged upward, and the top end of the piston rod of the lifting drive cylinder 3010 is fixedly connected to the bottom of the lifting mounting frame 302 via a floating joint, thereby pushing the lifting mounting frame 302 to move upward. A chain support plate 3011 is fixedly installed on one side of the lifting mounting frame 302 near the power chain 305. The top surface of the chain support plate 3011 contacts the bottom surface of the upper part of the chain segment of the power chain 305, and the chain support plate 3011 provides support for the upper part of the chain area of ​​the power chain 305.

[0025] Specifically, after the device is used, when it is necessary to clean the remaining solid waste material and non-degradable particles on the top of the supporting tooth block 203, firstly, the sealed door at the bottom of the ash collection chamber 201 is opened to discharge the non-degradable particles collected at the bottom of the ash collection chamber 201. Then, the sealed door is locked back at the bottom of the ash collection chamber 201. Next, the piston rod of the lifting drive cylinder 3010 pushes the lifting mounting frame 302 upward, causing the driven sprocket 303, the driving sprocket 304, the power chain 305, and the sheet metal bending blocks 306 to move upward together. This causes the bent part of each sheet metal bending block 306 to engage with the corresponding clearance groove 308 on the side of the deflection block 301. At the same time, the sheet metal bending blocks 306 will move upward to the position where they mesh with the unloading sprocket 309. When the geared motor 307 is started, the power chain 305 continues to rotate. This, through the sheet metal bending lever 306, simultaneously drives all the deflection levers 301 and the corresponding connected support rollers 202 to rotate synchronously. At this time, the support rollers 202 drive each support tooth block 203 to rotate as a whole, causing the non-pyrolytic particles and remaining solid waste materials originally supported on the top of the support tooth blocks 203 to be tilted downwards. They fall into the ash collection chamber 201 below through the gaps between adjacent support tooth blocks 203. Finally, by opening the sealed door at the bottom of the ash collection chamber 201, all non-pyrolytic particles and remaining solid waste materials can be discharged uniformly. No operator is required to enter the device for cleaning, which greatly improves the safety of slag and ash removal operations. The entire process is automated, and the ash removal efficiency is higher.

[0026] A method for using a photothermal energy storage multi-wave field time-series coupled cryogenic pyrolysis gasification device includes the following steps: S1. The solid waste material is pyrolyzed at low temperature on the upper end of the support structure composed of several support blocks 203. During the low temperature pyrolysis of the solid waste material, some fine particles that cannot be pyrolyzed will fall naturally from the gap between adjacent support blocks 203 to the bottom of the ash collection chamber 201 for collection. S2. During the pyrolysis and gasification operation, the output shaft of the reduction motor 307 drives the drive sprocket 304 to rotate, which in turn drives the driven sprocket 303 to rotate synchronously through the power chain 305. During the rotation, the sheet metal bending block 306 on the power chain 305 passes through the position of the deflection block 301 in sequence, thereby pushing the side of the deflection block 301 and driving the corresponding connected support roller 202 to deflect at a small angle. This causes the support roller 202 to drive the support tooth block 203 fixed on its outer ring surface to deflect synchronously, causing the non-pyrolyzable particles stuck in the gap between adjacent support tooth blocks 203 to lose support and fall off. S3. After use, the piston rod of the lifting drive cylinder 3010 pushes the lifting mounting bracket 302 upward, causing the driven sprocket 303, the driving sprocket 304, the power chain 305, and the sheet metal bending blocks 306 to move upward together. This causes the bent portion of each sheet metal bending block 306 to engage with the corresponding clearance groove 308 on the side of the deflection block 301. At the same time, the sheet metal bending blocks 306 will move upward to engage with the unloading sprocket 309. At this time, the reduction motor 307 is started to drive the power chain 305 to continue. Rotation causes the sheet metal bending lever 306 to simultaneously drive all the deflection levers 301 and the corresponding connected support rollers 202 to rotate synchronously. At this time, the support rollers 202 drive each support tooth block 203 to rotate as a whole, causing the non-degradable particles that were originally supported on the top of the support tooth block 203 to tilt downwards. The non-degradable particles fall into the ash collection chamber 201 below through the gap between adjacent support tooth blocks 203. Finally, opening the sealing door at the bottom of the ash collection chamber 201 allows all the non-degradable particles to be discharged uniformly.

[0027] The working principle of a photothermal energy storage multi-wavefield time-sequential coupling low-temperature pyrolysis and gasification device in this scheme is as follows: Solid waste material undergoes low-temperature pyrolysis at the top of a support structure composed of several support blocks 203. During the low-temperature pyrolysis process, some fine, non-pyrolytic particles naturally fall from the gaps between adjacent support blocks 203 to the bottom of the ash collection chamber 201 for collection. However, some non-pyrolytic particle residue remains stuck at the top of the support blocks 203 and in the gaps, unable to fall naturally. Therefore, during the low-temperature pyrolysis process, the reduction motor 307 needs to be activated. The output shaft of the reduction motor 307 drives the drive sprocket 304 to rotate slowly and uniformly. The drive sprocket 304 drives the power chain sleeved on the outside. The strip 305 rotates cyclically, and through the power chain 305, it drives the sheet metal bending block 306 to move cyclically along the rotation trajectory of the power chain 305. During the movement of the sheet metal bending block 306, its bent part will contact the side of the deflection block 301, thereby pushing the side of the deflection block 301 and driving the corresponding connected support roller 202 to deflect at a small angle. This causes the support roller 202 to drive the support tooth block 203 fixed on its outer ring surface to deflect synchronously, so that the solid waste non-pyrolytic particle residue stuck in the gap between adjacent support tooth blocks 203 loses support and falls off, completing the residue in the pyrolysis process. The automatic discharge of slag eliminates the need for manual cleaning, reducing maintenance costs. Furthermore, since the first ends of several support rollers 202 are simultaneously meshed with multiple drive sprockets 204 via a synchronous chain 205, when any one support roller 202 deflects, the others deflect synchronously, ensuring that all support blocks 203 move in unison. This achieves comprehensive and stable discharge of non-pyrolytic particulate residue from solid waste pyrolysis. During the deflection of the support rollers 202, the eccentric counterweight 206 also deflects at a certain angle, causing its center of gravity to shift away from its normal position. The bottom of the axis of the support roller 202 is supported. As the sheet metal bending block 306 continues to move, the sheet metal bending block 306 eventually finishes pushing the side of the deflection block 301. At this time, the eccentric counterweight block 206 resets under its own gravity, driving the entire support roller 202 to deflect and reset in the opposite direction, waiting for the next side push of the sheet metal bending block 306. This cycle can realize the continuous reciprocating small angle swing of the support roller 202 and the support tooth block 203, continuously loosening and dropping the stuck solid waste non-pyrolytic particle residue. The residue discharge operation will not affect the continuous low temperature pyrolysis operation of the entire device. After the device is used, when it is necessary to clean the residual solid waste and pyrolysis residue on the top of the support block 203, first open the sealing door at the bottom of the ash collection chamber 201 to discharge the non-pyrolyzable particulate residue collected at the bottom of the ash collection chamber 201, and then lock the sealing door at the bottom of the ash collection chamber 201 again. Next, the piston rod of the lifting drive cylinder 3010 pushes the lifting mounting bracket 302 upward, which drives the driven sprocket 303, the driving sprocket 304, the power chain 305, and the sheet metal bending block 306 to move upward together, so that the bent part of each sheet metal bending block 306 is engaged in the corresponding clearance groove 308 opened on the side of the deflection block 301. At the same time, the sheet metal bending block 306 will move upward to the position of engaging with the unloading sprocket 309. At this time, the reduction motor is activated. The drive chain 305 of the machine 307 continues to rotate, which in turn drives all the deflection blocks 301 and the corresponding support rollers 202 to rotate synchronously through the sheet metal bending block 306. At this time, the support rollers 202 drive each support tooth block 203 to rotate as a whole, and the residual solid waste material and pyrolysis residue originally supported on the top of the support tooth block 203 are tilted downwards. The residue falls into the ash collection chamber 201 below through the gap between adjacent support tooth blocks 203. Finally, the sealing door at the bottom of the ash collection chamber 201 is opened to discharge all the pyrolysis residue and residual non-pyrolyzable particles in a unified manner. No operator is required to enter the device for cleaning, which greatly improves the safety of slag discharge and cleaning operations. The whole process is completed automatically, and the slag discharge efficiency after the low temperature pyrolysis of solid waste is higher.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.

The method of using the photothermal energy storage multi-wave field time-series coupled low-temperature pyrolysis gasification device according to claim 9, characterized in that: The following usage steps are included: S1. The solid waste material is decomposed at low temperature at the upper end of the support structure composed of several support blocks (203). During the low temperature decomposition of the solid waste material, some fine particles that cannot be decomposed will fall naturally from the gap between adjacent support blocks (203) to the bottom of the ash collection chamber (201) for collection. S2. During the pyrolysis and gasification operation, the output shaft of the geared motor (307) drives the active sprocket (304) to rotate, which in turn drives the driven sprocket (303) to rotate synchronously through the power chain (305). During the rotation, the sheet metal bending block (306) on the power chain (305) passes through the position of the deflection block (301) in sequence, thereby pushing the side of the deflection block (301) and driving the corresponding connected support roller (202) to deflect at a small angle. This causes the support roller (202) to drive the support tooth block (203) fixed on its outer ring surface to deflect synchronously, causing the non-pyrolyzable particles stuck in the gap between adjacent support tooth blocks (203) to lose support and fall off. S3. After use, the piston rod of the lifting drive cylinder (3010) pushes the lifting mounting bracket (302) upward, causing the driven sprocket (303), the driving sprocket (304), the power chain (305), and the sheet metal bending blocks (306) to move upward together, so that the bent part of each sheet metal bending block (306) is engaged in the corresponding clearance groove (308) on the side of the deflection block (301). At the same time, the sheet metal bending blocks (306) will move upward to the position of engaging with the unloading sprocket (309). At this time, the reduction motor (307) is started to drive the power chain (301) (302). 5) Continue to rotate, and the sheet metal bending block (306) will simultaneously drive all the deflection blocks (301) and the corresponding connected support rollers (202) to rotate synchronously. At this time, the support rollers (202) will drive each support tooth block (203) to rotate as a whole, and the non-degradable particles that were originally supported on the top of the support tooth block (203) will be tilted downwards. The non-degradable particles will fall into the ash collection chamber (201) below through the gap between adjacent support tooth blocks (203). Finally, the sealing door at the bottom of the ash collection chamber (201) can be opened to discharge all the non-degradable particles.
