Description

Technical Field

[0001] The present invention belongs to the technical field of biomass pyrolysis, and particularly relates to a control system and method for a biomass pyrolysis gasification boiler. Background Art

[0002] Biomass pyrolysis refers to the process in which biomass is heated and decomposed into coke, condensable liquids, and gas products under anaerobic or low-oxygen conditions. During the biomass pyrolysis process, a pyrolysis device is required. Generally, the pyrolysis device includes a pyrolysis mechanism and a product conveying mechanism. The pyrolysis gas generated through pyrolysis is output through a gas conduit for collection.

[0003] In the prior art, before biomass pyrolysis, the biomass usually needs to be broken into granular form, and then the biomass granules are poured into a pyrolysis furnace. Through heating, pyrolysis, and gasification in a closed environment, the pyrolysis gas generated during the pyrolysis process is output for collection, while the coke generated by pyrolysis remains in the pyrolysis furnace. After the pyrolysis is completed, the pyrolysis gasification of the next batch of biomass can be continued.

[0004] After the above pyrolysis control method completes the biomass pyrolysis, the pyrolysis furnace cover needs to be opened to clean out the coke, and then the next batch of biomass granules needs to be poured into the pyrolysis furnace to continue the pyrolysis gasification. However, this process easily causes convection between the pyrolysis furnace and the external air, resulting in a large amount of heat loss inside the pyrolysis furnace, which is not conducive to the efficient pyrolysis of the next batch of biomass. At the same time, the biomass in the existing pyrolysis furnace is in a stacked state, which is not conducive to the full pyrolysis gasification of the biomass. Therefore, we provide a control system and method for a biomass pyrolysis gasification boiler to solve the above problems. Summary of the Invention

[0009] The present invention is further configured such that the fabric assembly further includes a box mounting seat slidably fitted inside the feeding cylinder cover. A material transfer channel is fixedly installed on the top of the box mounting seat, and the storage box is fixedly installed on the top of the material transfer channel and the two are communicated.

An arc-shaped blocking plate for blocking the limiting channel is fixedly arranged at the bottom of the box mounting seat. A limiting opening is formed at the top of the box mounting seat. The inclined surface fabric portion includes an inverted V-shaped fabric plate, which is arranged below the box mounting seat and fixedly connected to the box mounting seat through a support rod. Oblique guide plates are installed at positions close to the bottom on both opposite sides of the inverted V-shaped fabric plate. A plurality of blanking slots are formed on the surface of the inverted V-shaped fabric plate.

[0010] The present invention is further configured such that the intermittent material transfer assembly includes a hollow material transfer body rotatably arranged inside the material transfer channel. A feed inlet is formed on the circumferential side of the hollow material transfer body. One end of the hollow material transfer body is fixedly provided with a material transfer control shaft passing through the corresponding limiting channel. A traveling gear meshing with the vertical toothed plate is fixedly installed at the end of the material transfer control shaft. A moving seat is slidably arranged inside the limiting channel corresponding to the vertical toothed plate. The outer surface of the moving seat is a curved surface structure and fits with the outer wall of the feeding cylinder cover. The inner surface of the moving seat is a curved surface structure and fits with the inner wall of the feeding cylinder cover. The moving seat is sleeved on the material transfer control shaft and the two are rotatably connected.

[0011] The present invention is further configured such that the sealed lifting plate is slidably fitted on the inner wall of the pyrolysis gasification furnace. An arc-shaped sealed opening adapted to the arc-shaped blocking plate is formed on the circumferential side of the sealed lifting plate. A second through opening is formed on the surface of the sealed lifting plate.

The moving frame is sleeved on the lifting control rod and the two are in threaded cooperation. A biomass loading plate is arranged below the sealed lifting plate. The biomass loading plate is connected to the sealed lifting plate through a vertical fixing rod. The top sealing plate is used to block the second through opening.

[0012] The present invention is further configured such that a bearing base communicated with the pyrolysis gasification furnace is fixedly arranged at the bottom of the pyrolysis gasification furnace. A conical material gathering ring is fixedly installed on the top of the first partition plate. A first discharge port located inside the conical material gathering ring is formed on the surface of the first partition plate.

A horizontal through port which is adapted to the horizontal rack is formed in the peripheral side surface of the pyrolysis gasification furnace.

[0014] The present invention has the following beneficial effects: 1. By arranging two top sealing plates on the sealed lifting disc in the present invention, the upward moving top sealing plate rotates downward to the vertical state after contacting the end of the inverted V-shaped cloth plate. After a batch of biomass pyrolysis gasification treatment is completed, the next batch of biomass particles on the biomass loading plate can be evenly laid and pyrolyzed and gasified under the condition of keeping the pyrolysis gasification chamber isolated from the external air according to the same control method. In this way, the non-piled and sealed feeding pyrolysis gasification process of biomass particles can be realized, and a large amount of heat loss caused by air convection between the external air and the pyrolysis gasification chamber during the biomass particle feeding process can be effectively avoided.

[0015] 2. When a batch of biomass pyrolysis gasification treatment is completed in the present invention, the horizontal moving plate is controlled to move close to the pyrolysis gasification furnace, and the pushing plate scrapes along the surface of the biomass loading plate to push away the pyrolyzed coke. The coke slides along the conical material gathering ring and gathers on the first partition plate. During this process, the horizontal rack drives the discharge gear to rotate. During the rotation of the bottom sealing disc, the coke is rotated and pushed into the first discharge port through the material guiding plate. When the second discharge port is communicated with the first discharge port, the coke falls for collection. When the pushing plate just disengages from the biomass loading plate, during the reset process of the pushing plate and the horizontal rack, the bottom sealing disc is driven to rotate, and further part of the coke falls along the second discharge port for collection. By controlling the rotation speed of the bottom sealing disc, the communication time between the second discharge port and the first discharge port will not be too long, so as to reduce the influence of air on the internal temperature of the pyrolysis gasification chamber.

[0016] 3. When the sealed lifting disc abuts against the bottom of the box body mounting seat in the present invention, as the lifting control rod continues to rotate, the entire sealed loading assembly is driven to move upward continuously. The sealed lifting disc pushes the entire cloth assembly to move upward synchronously. During this process, the walking gear rolls along the vertical toothed plate. When the feed port on the hollow rotating body turns downward, the biomass particles in the hollow rotating body fall along the feed port onto the inverted V-shaped cloth plate, and the biomass particles falling onto the inverted V-shaped cloth plate fall onto the biomass loading plate along the respective material falling slots, so that the biomass particles are evenly laid on the surface of the biomass loading plate.

Specific embodiments

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0035] For specific embodiment 1, please refer to Figures 1 - 14, the present invention is a control system for a biomass pyrolysis gasification boiler, including a furnace body structure 1, and the furnace body structure 1 includes a pyrolysis gasification furnace 101; a feeding cylinder cover 2 is installed on the top of the pyrolysis gasification furnace 101, and a cloth feeding control mechanism 3 is arranged between the feeding cylinder cover 2 and the pyrolysis gasification furnace 101; wherein, the furnace body structure 1 further includes a pyrolysis gasification chamber 102 and a vertical tooth plate 104, the pyrolysis gasification chamber 102 is arranged inside the pyrolysis gasification furnace 101, and a pyrolysis gas outlet pipe 103 communicating with the pyrolysis gasification chamber 102 is installed on the periphery of the pyrolysis gasification furnace 101, and the pyrolysis gas generated during the pyrolysis process can be led out through the pyrolysis gas outlet pipe 103 for collection and treatment; the vertical tooth plate 104 is fixedly installed on one side of the pyrolysis gasification furnace 101.

[0036] The cloth feeding control mechanism 3 includes a cloth feeding component 4, an intermittent feeding component 5 and a sealed material loading component 6 (wherein the cloth feeding component 4 and the sealed material loading component 6 are made of light materials to realize the smooth up and down movement of the cloth feeding component 4 and the sealed material loading component 6); the cloth feeding component 4 is slidably arranged inside the feeding cylinder cover 2, and the cloth feeding component 4 includes a storage tank 401 and an inclined cloth feeding part arranged below it; the intermittent feeding component 5 is rotatably installed inside the storage tank 401 and meshes with the vertical tooth plate 104, and the intermittent feeding component 5 is used to transfer biomass particles from the storage tank 401 to the inclined cloth feeding part, and the biomass particles falling on the inclined cloth feeding part roll down under the action of their own gravity; the sealed material loading component 6 is slidably arranged inside the pyrolysis gasification furnace 101, and the sealed material loading component 6 includes a sealed lifting disc 601 for pushing the cloth feeding component 4 to move, and two top sealing plates 602 are installed on the sealed lifting disc 601 through torsion springs, and when the top sealing plates 602 contact the inclined cloth feeding part, they are deflected downward by the force (the two top sealing plates 602 are in a horizontal state in the initial state, as Figure 3 shown, at this time the pyrolysis gasification chamber 102 is in a sealed state under the action of the two top sealing plates 602).

[0037] In this embodiment of the present invention, a first partition plate 105 and a second partition plate 106 are fixedly arranged inside the pyrolysis gasification furnace 101 from bottom to top. The pyrolysis gasification chamber 102 is arranged between the first partition plate 105 and the second partition plate 106. A first through port 107 is formed on the surface of the second partition plate 106. An annular heat insulation seat 108 is fixedly installed on the peripheral side surface of the pyrolysis gasification furnace 101. A first strengthening frame 109 and a second strengthening frame 110 are respectively installed on the peripheral side surface of the annular heat insulation seat 108. A lifting control rod 112 is rotatably installed inside the first strengthening frame 109. The output end of a first motor 111 installed inside the first strengthening frame 109 is connected to the lifting control rod 112. By controlling the rotation of the lifting control rod 112, the up-and-down reciprocating movement of the sealed loading assembly 6 can be realized. A vertical toothed plate 104 is fixedly installed inside the second strengthening frame 110; The feeding cylinder cover 2 is supported on the top of the pyrolysis gasification furnace 101 and the two are connected by fasteners. The inner diameter of the feeding cylinder cover 2 is the same as the inner diameter of the pyrolysis gasification furnace 101 (to ensure that the sealed lifting plate 601 can slide upward along the inner wall of the pyrolysis gasification furnace 101 into the feeding cylinder cover 2 or slide downward from the inner wall of the feeding cylinder cover 2 into the pyrolysis gasification furnace 101). Two vertically arranged limiting channels 201 are symmetrically formed on the peripheral side surface of the feeding cylinder cover 2.

[0038] In this embodiment of the present invention, the cloth feeding assembly 4 further includes a box body mounting seat 402 slidably fitted inside the feeding cylinder cover 2. A transfer channel 403 is fixedly installed on the top of the box body mounting seat 402. The storage box 401 is fixedly installed on the top of the transfer channel 403 and the two are connected and communicated; A limiting member 404 slidably fitted with the corresponding limiting channel 201 is fixedly arranged on the peripheral side surface of the box body mounting seat 402 (that is, the limiting member 404 and the limiting channel 201 are arranged in one-to-one correspondence). An arc-shaped sealing plate 405 for blocking the limiting channel 201 is fixedly arranged at the bottom of the box body mounting seat 402 (the outer wall of the arc-shaped sealing plate 405 is attached to the inner wall of the feeding cylinder cover 2 to ensure that during the upward movement of the box body mounting seat 402, the arc-shaped sealing plate 405 can block each limiting channel 201 to prevent external air from entering the space below the box body mounting seat 402 along the limiting channel 201, that is, to prevent external air from entering the pyrolysis gasification chamber 102 inside the pyrolysis gasification furnace 101 through the limiting channel 201). A limiting port 406 is formed on the top of the box body mounting seat 402;

[0039] The inclined surface material distribution part includes an inverted V-shaped material distribution plate 407. The inverted V-shaped material distribution plate 407 is arranged below the box body mounting seat 402, and the two are fixedly connected through a support rod 408. Oblique guide plates 409 are installed at positions close to the bottom on both opposite sides of the inverted V-shaped material distribution plate 407. A plurality of blanking notches 410 are formed on the surface of the inverted V-shaped material distribution plate 407. The blanking notches 410 are evenly formed on the surface of the inverted V-shaped material distribution plate 407 (that is, the blanking notches 410 are formed on both opposite inclined surfaces of the inverted V-shaped material distribution plate 407). Each blanking notch 410 is in a shape structure with a narrow upper part and a wide lower part, that is, the diameter of the blanking notch 410 gradually changes from top to bottom. In this way, it can be ensured to the greatest extent that the biomass particles rolling along the inclined surface of the inverted V-shaped material distribution plate 407 are evenly dispersed and fall. The biomass particles falling onto the inverted V-shaped material distribution plate 407 roll downward and fall along each blanking notch 410 to the required positions. Through the arrangement of the oblique guide plates 409, it can be ensured that the biomass particles completely fall through each blanking notch 410 and will not roll out of the inverted V-shaped material distribution plate 407 from other positions.

[0040] In this embodiment of the present invention, the intermittent material transfer assembly 5 includes a hollow material transfer body 501 rotatably arranged inside the material transfer channel 403. A feed inlet 502 is formed on the circumferential side surface of the hollow material transfer body 501 (in the initial state, the feed inlet 502 on the hollow material transfer body 501 is vertically upward. At this time, the biomass particles in the storage box 401 enter the hollow material transfer body 501 through the feed inlet 502, and the space below the storage box 401 and the box body mounting seat 402 is blocked by the hollow material transfer body 501). One end of the hollow material transfer body 501 is fixedly provided with a material transfer control shaft 503 penetrating through the corresponding limit channel 201. A traveling gear 504 meshing with the vertical tooth plate 104 is fixedly installed at the end of the material transfer control shaft 503. A moving seat 505 is slidably arranged inside the limit channel 201 corresponding to the vertical tooth plate 104. The outer surface of the moving seat 505 is a curved surface structure and fits with the outer wall of the material conveying cylinder cover 2. The inner surface of the moving seat 505 is a curved surface structure and fits with the inner wall of the material conveying cylinder cover 2. The moving seat 505 is sleeved on the material transfer control shaft 503 and the two are rotatably connected. By slidably arranging the moving seat 505 inside the limit channel 201 and making the material transfer control shaft 503 rotate and cooperate with the moving seat 505, it can be ensured that the intermittent material transfer assembly 5 moves up and down smoothly without deviation.

[0041] In this embodiment of the present invention, the sealed lifting plate 601 is slidably fitted on the inner wall of the pyrolysis gasification furnace 101. An arc-shaped sealed opening 603 adapted to the arc-shaped sealing plate 405 (i.e., the arc-shaped sealing plates 405 and the arc-shaped sealed openings 603 are in one-to-one correspondence) is provided on the circumferential side surface of the sealed lifting plate 601. A second through opening 604 is provided on the surface of the sealed lifting plate 601. A moving frame 605 slidably fitted with the corresponding limiting channel 201 is fixedly provided at the top of the sealed lifting plate 601. The moving frame 605 slidably penetrates through the limiting opening 406. The moving frame 605 is sleeved on the lifting control rod 112 and the two are in threaded cooperation. A biomass loading plate 606 is provided below the sealed lifting plate 601. The biomass loading plate 606 and the sealed lifting plate 601 are connected by a vertical fixing rod 607. The top sealing plate 602 is used to block the second through opening 604.

[0042] As Figure 3 shown, in the initial state, the limiting member 404 on the box mounting seat 402 abuts against the bottom of the corresponding limiting channel 201. The sealed lifting plate 601 is attached to the top of the second partition plate 106. At this time, both top sealing plates 602 are in a horizontal state. The biomass loading plate 606 is located in the pyrolysis gasification chamber 102 (heating components are installed in the pyrolysis gasification chamber 102). At this time, the pyrolysis gasification chamber 102 is in a sealed state. The feeding port 502 on the hollow rotating material body 501 is vertically upward. The biomass particles in the storage box 401 enter the hollow rotating material body 501 through the feeding port 502.

[0043] The controller controls the first motor 111 to start, and controls the lifting control rod 112 to rotate through the first motor 111. Under the threaded cooperation between the lifting control rod 112 and the moving frame 605, the moving frame 605 is driven to move upward along the corresponding limiting channel 201, driving the sealed lifting plate 601 to move upward synchronously. During this process, each arc-shaped sealing plate 405 gradually slides into the corresponding arc-shaped sealed opening 603. The sealed lifting plate 601 gradually approaches the box mounting seat 402. The two top sealing plates 602 remain in a horizontal state and move upward synchronously with the sealed lifting plate 601 until the two top sealing plates 602 just contact the ends of the inverted V-shaped cloth plate 407 (i.e., the left top sealing plate 602 contacts the left end of the inverted V-shaped cloth plate 407, and the right top sealing plate 602 contacts the right end of the inverted V-shaped cloth plate 407). During the above process, the entire cloth assembly 4 remains stationary.

[0044] When the two top sealing plates 602 just come into contact with the end of the inverted V-shaped cloth plate 407, as the lifting control rod 112 continues to rotate, it drives the entire sealed material-carrying assembly 6 to move upward. During this process, both of the top sealing plates 602 on both sides are pressed by the end of the inverted V-shaped cloth plate 407, causing both of the top sealing plates 602 on both sides to rotate downward until the sealed lifting plate 601 just fits against the bottom of the box mounting seat 402. At this time, both of the top sealing plates 602 on both sides rotate to an upright state and are located on the opposite sides of the inverted V-shaped cloth plate 407 (as Figure 9 shown), the biomass material-carrying plate 606 is close to the bottom of the inverted V-shaped cloth plate 407, and the end of the inverted V-shaped cloth plate 407 and the inclined guide plate 409 are both in contact with the top sealing plate 602 (in this way, it can be avoided that biomass particles roll out of the inverted V-shaped cloth plate 407 along the end of the inverted V-shaped cloth plate 407). At this time, the biomass material-carrying plate 606 is located above the pyrolysis gasification chamber 102.

[0045] After the sealed lifting plate 601 abuts against the bottom of the box mounting seat 402, as the lifting control rod 112 continues to rotate, it drives the entire sealed material-carrying assembly 6 to move upward. At this time, the sealed lifting plate 601 pushes the entire cloth assembly 4 to move upward synchronously. During this process, the traveling gear 504 rolls along the vertical toothed plate 104. When the feed port 502 on the hollow rotating material body 501 rotates downward, the biomass particles in the hollow rotating material body 501 fall along the feed port 502 to the inverted V-shaped cloth plate 407 under the action of their own gravity. The biomass particles falling onto the inverted V-shaped cloth plate 407 gradually roll down along the inclined surfaces on both sides. During the downward rolling process of the biomass particles, the biomass particles are scattered and fall through the inverted V-shaped cloth plate 407 through the flaring hopper 410 with a narrow upper part and a wide lower part. The biomass particles falling through the inverted V-shaped cloth plate 407 are scattered onto the biomass material-carrying plate 606, so that the biomass particles are evenly laid on the surface of the biomass material-carrying plate 606. Compared with the prior art method of pouring biomass particles into the boiler at one time, the above cloth method in this application can realize the even cloth of biomass particles. Since the end of the inverted V-shaped cloth plate 407 and the inclined guide plate 409 are both in contact with the top sealing plate 602, the biomass particles rolling along the inverted V-shaped cloth plate 407 cannot roll out from its end. At the same time, under the action of the inclined guide plate 409, the biomass particles rolling onto the inclined guide plate 409 are forced to fall along the flaring hopper 410 to the biomass material-carrying plate 606.

[0046] After the sealed lifting plate 601 pushes the entire cloth feeding assembly 4 to move upward synchronously to the designated position, as the lifting control rod 112 rotates in the reverse direction, the entire sealed material loading assembly 6 is driven to move downward. The cloth feeding assembly 4 moves downward synchronously with the sealed lifting plate 601. During this process, the walking gear 504 further rolls along the vertical toothed plate 104, causing the hollow material transfer body 501 to rotate again, so that a certain amount of biomass particles are laid on the biomass material loading plate 606. After the cloth feeding assembly 4 moves downward to the initial position (that is, the limiting member 404 on the box body mounting seat 402 abuts against the bottom of the corresponding limiting channel 201), the sealed material loading assembly 6 is continuously controlled to move downward so that the sealed lifting plate 601 disengages from the box body mounting seat 402 until the sealed lifting plate 601 fits against the top of the second partition plate 106 again. At this time, the two top sealing plates 602 are reset to the horizontal state under the action of the torsion spring to seal the pyrolysis gasification chamber 102. The biomass material loading plate 606 paved with biomass particles returns to the pyrolysis gasification chamber 102, and then the pyrolysis gasification treatment of biomass is started by controlling the temperature rise of the pyrolysis gasification chamber 102.

[0047] After completing the pyrolysis gasification treatment of this batch of biomass, according to the same control method as above, the uniform laying and pyrolysis gasification of biomass particles in the upper and lower batches of the biomass material loading plate 606 can be realized while keeping the pyrolysis gasification chamber 102 isolated from the external air. In this way, the non-piled and sealed feeding pyrolysis gasification process of biomass particles can be realized, effectively avoiding a large amount of heat loss caused by air convection between the external air and the pyrolysis gasification chamber 102 during the feeding process of biomass particles.

[0048] Specific embodiment two: On the basis of specific embodiment one, a bearing base 113 connected to it is fixedly arranged at the bottom of the pyrolysis gasification furnace 101. A conical material gathering ring 114 is fixedly installed on the top of the first partition plate 105. A first discharge port 115 located inside the conical material gathering ring 114 is formed on the surface of the first partition plate 105. A bottom sealing plate 116 is rotatably arranged at the bottom of the first partition plate 105. A second discharge port 117 adapted to the first discharge port 115 is formed on the surface of the bottom sealing plate 116. A material stirring plate 118 (which is in contact with the inner wall of the conical material gathering ring 114) is connected to the top of the bottom sealing plate 116 through a rotating shaft. A discharge gear 119 is connected to the bottom of the bottom sealing plate 116 through a rotating shaft.

[0049] In this embodiment of the present invention, a support base 120 is fixedly installed on the peripheral side of the pyrolysis gasification furnace 101. Inside the support base 120, a horizontal moving plate 121 is arranged. On the surface of the horizontal moving plate 121, a moving rod 122 and a horizontal rack 123 that are slidably matched with the pyrolysis gasification furnace 101 are fixedly arranged. A limiting guide plate 128 that is slidably connected with the horizontal rack 123 is fixed on the inner wall of the pyrolysis gasification furnace 101 to improve the stability of the meshing transmission process between the horizontal rack 123 and the discharge gear 119. The end of the moving rod 122 is fixedly provided with a pushing plate 124. A second motor 125 is installed outside the support base 120. The output end of the second motor 125 is connected with a horizontal screw rod 126 that is in threaded cooperation with the horizontal moving plate 121. A horizontal through port 127 that is adapted to the horizontal rack 123 is opened on the peripheral side of the pyrolysis gasification furnace 101; when a batch of biomass pyrolysis gasification treatment is completed, the controller controls the second motor 125 to start and drive the horizontal screw rod 126 to rotate. Under the threaded cooperation between the horizontal screw rod 126 and the horizontal moving plate 121, the horizontal moving plate 121 moves closer to the pyrolysis gasification furnace 101. The moving rod 122 that moves synchronously with the horizontal moving plate 121 drives the pushing plate 124 to scrape along the surface of the biomass loading plate 606, and the coke after pyrolysis on the biomass loading plate 606 can be pushed away from the biomass loading plate 606. The coke that detaches from the biomass loading plate 606 slides along the conical material gathering ring 114 and accumulates on the first partition plate 105 (specifically, the coke accumulates at the position of the first discharge port 115). During this process, the horizontal rack 123 that moves synchronously with the horizontal moving plate 121 drives the discharge gear 119 to rotate. During the rotation of the bottom sealing plate 116, the coke is rotated and pushed into the first discharge port 115 through the material deflecting plate 118. The coke that enters the inside of the first discharge port 115 is supported by the bottom sealing plate 116. When the second discharge port 117 is communicated with the first discharge port 115, the coke inside the first discharge port 115 can fall along the second discharge port 117 to achieve collection. When the pushing plate 124 just detaches from the biomass loading plate 606, the second motor 125 controls the horizontal screw rod 126 to rotate in the reverse direction, so that the pushing plate 124 and the horizontal rack 123 both move in the reverse direction and return to the initial positions (at this time, the pushing plate 124 is located on one side of the biomass loading plate 606). During the reset process, the horizontal rack 123 continues to drive the rotation of the bottom sealing plate 116, and further realizes the collection of part of the coke falling along the second discharge port 117. The communication time between the second discharge port 117 and the first discharge port 115 can be controlled by controlling the rotation speed of the bottom sealing plate 116 to be not too long to reduce the influence of air on the temperature inside the pyrolysis gasification chamber 102. Subsequently, the airtight loading assembly 6 can be controlled to continue to move upward.

[0050] Specific Embodiment Three, the present invention further includes a working method for a biomass pyrolysis gasification boiler control system, including the following steps:

[0051] S01. The controller controls the first motor 111 to start, and controls the lifting control rod 112 to rotate through the first motor 111. Under the screw thread fit between the lifting control rod 112 and the moving frame 605, the moving frame 605 is driven to move upward along the corresponding limiting channel 201, driving the airtight lifting plate 601 to move upward synchronously. During this process, each arc-shaped sealing plate 405 gradually slides into the corresponding arc-shaped airtight opening 603, and the airtight lifting plate 601 gradually approaches the box body mounting seat 402. The two top sealing plates 602 remain in a horizontal state and move upward synchronously with the airtight lifting plate 601 until the two top sealing plates 602 just contact the end of the inverted V-shaped cloth plate 407. The entire cloth assembly 4 remains stationary during the above process;

[0052] S02. After the two top sealing plates 602 just contact the end of the inverted V-shaped cloth plate 407, as the lifting control rod 112 continues to rotate, the entire airtight material loading assembly 6 is driven to move upward. During this process, both side top sealing plates 602 are pressed by the end of the inverted V-shaped cloth plate 407, so that both side top sealing plates 602 rotate downward until the airtight lifting plate 601 just fits against the bottom of the box body mounting seat 402. At this time, both side top sealing plates 602 rotate to an upright state and are located on the opposite sides of the inverted V-shaped cloth plate 407. The biomass material loading plate 606 is close to the bottom of the inverted V-shaped cloth plate 407. The end of the inverted V-shaped cloth plate 407 and the inclined guide plate 409 are both in contact with the top sealing plates 602. At this time, the biomass material loading plate 606 is located above the pyrolysis gasification chamber 102;

[0053] S03. After the airtight lifting plate 601 abuts against the bottom of the box body mounting seat 402, as the lifting control rod 112 continues to rotate, the entire airtight material loading assembly 6 is driven to move upward. At this time, the airtight lifting plate 601 pushes the entire cloth assembly 4 to move upward synchronously. During this process, the walking gear 504 rolls along the vertical toothed plate 104. When the feed inlet 502 on the hollow rotating material body 501 rotates downward, the biomass particles in the hollow rotating material body 501 fall along the feed inlet 502 onto the inverted V-shaped cloth plate 407. The biomass particles falling onto the inverted V-shaped cloth plate 407 fall onto the biomass material loading plate 606 along the respective material falling slots 410, so that the biomass particles are evenly laid on the surface of the biomass material loading plate 606;

[0054] S04. After the sealed lifting plate 601 pushes the entire cloth feeding assembly 4 to move upward synchronously to the designated position, as the lifting control rod 112 rotates in the reverse direction, the entire sealed material loading assembly 6 is driven to move downward, and the cloth feeding assembly 4 moves downward synchronously with the sealed lifting plate 601. During this process, the traveling gear 504 further rolls along the vertical toothed plate 104, causing the hollow material transfer body 501 to rotate again, so that a certain amount of biomass particles are laid on the biomass material loading plate 606. After the cloth feeding assembly 4 moves downward to the initial position, the sealed material loading assembly 6 is continuously controlled to move downward so that the sealed lifting plate 601 disengages from the box body mounting seat 402 until the sealed lifting plate 601 fits again on the top of the second partition plate 106. At this time, the two top sealing plates 602 are reset to the horizontal state under the action of the torsion spring to seal the pyrolysis gasification chamber 102. The biomass material loading plate 606 paved with biomass particles returns to the pyrolysis gasification chamber 102. Subsequently, the pyrolysis gasification chamber 102 is controlled to heat up to start the biomass pyrolysis gasification treatment;

[0055] S05. After completing the pyrolysis gasification treatment of this batch of biomass, according to the same control method above, the uniform laying and pyrolysis gasification of biomass particles in the upper and lower batches can be realized while keeping the pyrolysis gasification chamber 102 isolated from the external air. In this way, the non-piled and sealed feeding pyrolysis gasification process of biomass particles can be realized;

[0056] S06. When the pyrolysis gasification treatment of a batch of biomass is completed, the controller controls the second motor 125 to start, driving the horizontal screw 126 to rotate. Under the screw thread fit between the horizontal screw 126 and the horizontal moving plate 121, the horizontal moving plate 121 moves closer to the pyrolysis gasification furnace 101. The moving rod 122 moving synchronously with the horizontal moving plate 121 drives the pushing plate 124 to scrape along the surface of the biomass material loading plate 606, and the coke after pyrolysis on the biomass material loading plate 606 can be pushed away from the biomass material loading plate 606. The coke separated from the biomass material loading plate 606 slides down along the conical material gathering ring 114 and accumulates on the first partition plate 105. During this process, the horizontal rack 123 moving synchronously with the horizontal moving plate 121 drives the discharge gear 119 to rotate. During the rotation of the bottom sealing plate 116, the coke is rotated into the first discharge port 115 through the material pushing plate 118, and the coke entering the first discharge port 115 is supported by the bottom sealing plate 116;

[0057] S07. When the second discharge port 117 is in communication with the first discharge port 115, the coke inside the first discharge port 115 can fall along the second discharge port 117 to achieve collection. When the pusher plate 124 just disengages from the biomass loading plate 606, the second motor 125 is controlled to reverse the rotation of the horizontal screw 126, so that the pusher plate 124 and the horizontal rack 123 both move backward to their initial positions. During the reset process, the horizontal rack 123 continues to drive the rotation of the bottom sealing plate 116, further enabling some coke to fall along the second discharge port 117 to achieve collection.

9. The working method of a biomass pyrolysis gasification boiler control system as claimed in claim 8, characterized in that, It includes the following steps: S01. The controller controls the first motor (111) to start, and controls the lifting control rod (112) to rotate through the first motor (111). Under the threaded cooperation of the lifting control rod (112) and the moving frame (605), the moving frame (605) is driven to move upward along the corresponding limiting channel (201) to drive the sealed lifting disc (601) to move upward synchronously. During this process, each arc-shaped sealing plate (405) gradually slides into the corresponding arc-shaped sealing opening (603). The sealed lifting disc (601) gradually approaches the box body mounting seat (402). The two top sealing plates (602) keep in a horizontal state and move upward synchronously with the sealed lifting disc (601) until the two top sealing plates (602) just contact the end of the inverted V-shaped cloth distributing plate (407). During the above process, the whole cloth distributing assembly (4) remains stationary. S02. After the two top sealing plates (602) just come into contact with the end of the inverted V-shaped cloth plate (407), as the lifting control rod (112) continues to rotate, it drives the entire sealed loading component (6) to continue moving upward. During this process, both of the top sealing plates (602) on both sides are pressed by the end of the inverted V-shaped cloth plate (407), thereby causing both of the top sealing plates (602) to rotate downward until the sealed lifting disc (601) just fits against the bottom of the box mounting seat (402). At this time, both of the top sealing plates (602) rotate to the upright state and are located on the opposite sides of the inverted V-shaped cloth plate (407). The biomass loading plate (606) is close to the bottom of the inverted V-shaped cloth plate (407). The end of the inverted V-shaped cloth plate (407) and the inclined guide plate (409) are both in contact with the top sealing plate (602). At this time, the biomass loading plate (606) is located above the pyrolysis gasification chamber (102). S03. After the sealed lifting disc (601) abuts against the bottom of the box mounting seat (402), as the lifting control rod (112) continues to rotate, it drives the entire sealed loading component (6) to continue moving upward. At this time, the sealed lifting disc (601) pushes the entire cloth component (4) to move upward synchronously. During this process, the traveling gear (504) rolls along the vertical toothed plate (104). When the feed port (502) on the hollow rotating material body (501) rotates downward, the biomass particles in the hollow rotating material body (501) fall along the feed port (502) onto the inverted V-shaped cloth plate (407). The biomass particles that fall onto the inverted V-shaped cloth plate (407) then fall along the respective material discharge slots (410) onto the biomass loading plate (606), so that the biomass particles are evenly laid on the surface of the biomass loading plate (606). S04. After the sealed lifting disc (601) pushes the entire cloth component (4) to move upward synchronously to the designated position, as the lifting control rod (112) rotates in the reverse direction, it drives the entire sealed loading component (6) to move downward. The cloth component (4) moves downward synchronously with the sealed lifting disc (601). During this process, the traveling gear (504) further rolls along the vertical toothed plate (104), causing the hollow rotating material body (501) to rotate again so that a certain amount of biomass particles are laid on the biomass loading plate (606). After the cloth component (4) moves downward to the initial position, continue to control the sealed loading component (6) to move downward so that the sealed lifting disc (601) disengages from the box mounting seat (402) until the sealed lifting disc (601) fits against the top of the second partition plate (106) again. At this time, the two top sealing plates (602) are reset to the horizontal state under the action of the torsion spring to seal the pyrolysis gasification chamber (102). The biomass loading plate (606) paved with biomass particles returns to the pyrolysis gasification chamber (102). Subsequently, start the biomass pyrolysis gasification treatment by controlling the temperature rise of the pyrolysis gasification chamber (102). S05. After completing the pyrolysis gasification treatment of this batch of biomass, the uniform laying and pyrolysis gasification of biomass particles in the upper and lower batches of the biomass loading plate (606) can be achieved under the same control mode as above while keeping the pyrolysis gasification chamber (102) isolated from the external air. In this way, the non-piled and airtight feeding pyrolysis gasification process of biomass particles can be realized; S06. When the pyrolysis gasification treatment of a batch of biomass is completed, the controller controls the second motor (125) to start and drive the horizontal screw (126) to rotate. Under the thread fit between the horizontal screw (126) and the horizontal moving plate (121), the horizontal moving plate (121) moves closer to the pyrolysis gasification furnace (101). The moving rod (122) that moves synchronously with the horizontal moving plate (121) drives the pushing plate (124) to scrape along the surface of the biomass loading plate (606), and the coke after pyrolysis on the biomass loading plate (606) can be pushed away from the biomass loading plate (606). The coke separated from the biomass loading plate (606) slides down along the conical material gathering ring (114) and accumulates on the first partition plate (105). During this process, the horizontal rack (123) that moves synchronously with the horizontal moving plate (121) drives the discharge gear (119) to rotate. During the rotation of the bottom sealing plate (116), the coke is rotated and pushed into the first discharge port (115) through the material pushing plate (118). The coke entering the inside of the first discharge port (115) is supported by the bottom sealing plate (116); S07. When the second discharge port (117) is communicated with the first discharge port (115), the coke inside the first discharge port (115) can fall along the second discharge port (117) for collection. When the pushing plate (124) just separates from the biomass loading plate (606), the second motor (125) controls the horizontal screw (126) to rotate in the reverse direction, so that the pushing plate (124) and the horizontal rack (123) both move back to their initial positions in the reverse direction. During the reset process, the horizontal rack (123) continues to drive the rotation of the bottom sealing plate (116), and further realizes the collection of part of the coke falling along the second discharge port (117).
