Description

Technical Field

[0001] This invention relates to the field of fluidized bed separation technology for sludge carbonization products, specifically to an apparatus and method for fluidized bed separation of municipal sludge carbonization products. Background Technology

[0002] After carbonization, municipal sludge produces a mixture containing carbon particles, inorganic impurities, and incompletely decomposed organic matter. A vibrating fluidized bed is needed to recover carbon resources and remove impurities. During operation, the vibrating fluidized bed uses mechanical vibration generated by a vibrator to loosen the material. Combined with hot air fluidization, the airflow passes through the material layer from bottom to top, causing the material particles to exhibit a fluidized state similar to a fluid. By utilizing the difference in settling velocity between light carbon particles and heavy inorganic impurities in the fluidized airflow, the separation of light and heavy particles can be achieved.

[0003] Because the carbonization products of municipal sludge are complex in composition, containing carbon particles, inorganic impurities, etc., some particles may agglomerate due to high-temperature carbonization. Existing fluidized bed air distribution plates cannot achieve uniform fluidization by only allowing airflow in one direction, which can easily lead to the accumulation of particles at the edges and the formation of localized stagnant areas, resulting in low sorting efficiency. The high-temperature carbonization products are highly viscous, and when light particles enter the separation channel with the airflow, they are easy to adhere to the inner wall of the channel and form accumulation, which can easily lead to blockage of the air inlet pipe in the long term. The sludge carbonization products are discharged at a high temperature, and the heavy particles are still in a high-temperature state when discharged, which can easily damage the subsequent conveying and storage equipment. Summary of the Invention

[0004] To address the problems in the prior art, this invention provides an apparatus and method for fluidized bed separation of carbonization products of municipal sludge.

[0005] The technical solution adopted by this invention to solve its technical problem is: a device for fluidized bed separation of municipal sludge carbonization products, including a vibration isolation spring, with a wind chamber fixedly connected to the top of the vibration isolation spring; vibrators fixedly installed on both sides of the wind chamber; two maintenance mechanisms and several hot air pipes installed on the wind chamber; an air distribution plate fixed inside the wind chamber; the wind chamber fixedly connected to a fluidization chamber through a sealing mechanism; a cooling mechanism installed near the end of the air distribution plate in the wind chamber and the fluidization chamber; a feeding hopper connected to the end of the fluidization chamber away from the cooling mechanism; and a separation mechanism fixed to the top of the fluidization chamber.

[0006] Specifically, the separation mechanism includes an air inlet pipe and guide plates. Two guide plates are connected internally to the fluidization chamber. An air inlet pipe is fixedly installed on each guide plate and is fixedly connected to the fluidization chamber. A sleeve is engaged at the end of the air inlet pipe, and a connecting pipe is engaged inside the other sleeve. The two sleeves are fixedly connected by bolts. A motor is fixedly installed on the sleeve near the connecting pipe. The output end of the motor is fixedly connected to a rotating shaft via a coupling. A gear is fixedly connected to the rotating shaft, and a gear ring meshes with the gear. A rotating cylinder is fixedly connected to the gear ring. The cylinder is rotatably connected to the connecting pipe, the air inlet pipe, and the sleeve. A scraper is fixedly connected to the cylinder, and the scraper is rotatably connected to the connecting pipe, the air inlet pipe, and the guide plate. A separation channel is fixedly installed at the top of the two connecting pipes, and an exhaust pipe is connected to the separation channel. The separation mechanism also includes washers. Two washers are symmetrically installed in the sleeve about the gear ring. The connecting pipe and the air inlet pipe are in contact with the washers. The inner diameter of the washers is larger than the diameter at both ends of the cylinder. The guide plate is set with a conical structure, and the part of the scraper near the guide plate is set with an inclined structure. The gear ring and the rotating shaft are rotatably connected to the sleeve.

[0007] Specifically, the air distribution plate has several sets of vertical through holes at its center and several sets of inclined through holes at both ends, with the two sets of inclined through holes having different inclination directions.

[0008] Specifically, the maintenance mechanism includes fixed rods and fixed rings. Two fixed rods are fixedly connected to the side of the air chamber away from the hot air duct. A fixed ring is rotatably installed on the fixed rod. An inspection door is fixedly connected to the fixed ring. A sealing ring is fixedly connected to the part of the air chamber near the inspection door. The inspection door and the sealing ring are engaged. A locking rod is fixedly connected to the part of the air chamber away from the fixed rods. The inspection door and the locking rod are engaged. A positioning block is threaded onto the locking rod. The inner diameter of the inspection door is equal to the diameter of the sealing ring. The positioning block abuts against the top of the fixed ring.

[0009] Specifically, the cooling mechanism includes a cooling pipe and a blower pipe. A cooling pipe is fixedly installed on the part of the fluidization chamber away from the feeding hopper. An installation block is fixedly connected to the cooling pipe. The installation block is fixedly connected to the fluidization chamber. A cold air pipe is connected to the cooling pipe. Two sets of blower pipes are symmetrically fixedly connected to the cooling pipe. Several guide rods are fixedly installed at equal intervals on the fluidization chamber. A guide plate is fixedly connected to the part of the fluidization chamber near the cooling pipe and the guide rods. A feeding hopper is fixedly installed on the part of the air chamber near the guide plate. A discharge pipe is fixedly connected to the bottom of the feeding hopper. The two sets of blower pipes are inclined. The feeding hopper and the guide plate are both inclined structures.

[0010] Specifically, the sealing mechanism includes a base plate and insertion holes. The top of the air chamber and the bottom of the fluidization chamber are both fixedly connected to the base plate. The base plate is provided with several sets of insertion holes. Several sets of connecting shafts are fixedly connected to the bottom of the base plate near the air chamber. A bracket is rotatably mounted on the connecting shaft. A lead screw is threadedly connected to the bracket. A rotating block and a stop block are fixedly mounted at both ends of the lead screw. An insertion rod is fixedly connected to the stop block. The insertion rod is engaged with the two base plates. The stop block abuts against the top of the base plate near the fluidization chamber.

[0011] Specifically, a method for fluidized bed separation of municipal sludge carbonization products includes the following steps: S1: First, the carbonized sludge products to be sorted are fed into the fluidization chamber through the feeding hopper. The vibrator is started, and then hot air is introduced into the air chamber through the hot air pipe. The hot air can enter the fluidization chamber through the vertical and inclined through holes in the air distribution plate to fluidize the material. S2: Furthermore, during the fluidization process, light particles enter the separation mechanism with the airflow. When the components installed in the separation mechanism rotate, they can scrape off the particles remaining in the separation mechanism. S3: Then the heavy particles move towards the cooling mechanism via the air distribution plate. When the cooling mechanism is started, cold air is introduced into the part of the air chamber to cool the material. S4: Finally, when the air chamber needs to be inspected, rotate to open the inspection mechanism to view the internal components of the air chamber.

[0012] The beneficial effects of this invention are: (1) The apparatus and method for fluidized bed separation of municipal sludge carbonization products of the present invention involves feeding the sludge carbonization products to be separated into the fluidization chamber through a feeding hopper, starting the vibrator, and then introducing hot air into the air chamber through a hot air pipe. The hot air can enter the fluidization chamber through the vertical and inclined through holes in the air distribution plate to fluidize the material. That is, the municipal sludge carbonization products (containing carbon particles, inorganic impurities, and other mixed particles) to be separated are fed into the fluidization chamber at a uniform speed through the feeding hopper, and the material initially accumulates on the side of the fluidization chamber near the feeding hopper; then the vibrators fixed on both sides of the air chamber are started. The vibration generated by the vibrator is transmitted to the fluidization chamber through the air chamber, which initially loosens the material in the fluidization chamber and reduces particle agglomeration. Then, hot air at a preset temperature is introduced into the air chamber through the hot air duct. After being buffered in the air chamber, the hot air enters the fluidization chamber through the vertical and inclined through holes of the air distribution plate. The vertical through holes in the central area form a uniform upward airflow, so that the material is fluidized as a whole. The inclined through holes at both ends of the air distribution plate generate lateral airflow, which pushes the material at the edge towards the center of the fluidization chamber, thereby avoiding local accumulation of material and enhancing material mixing and dispersion.

[0013] (2) The device and method for fluidized bed separation of municipal sludge carbonization products described in this invention, during the fluidization process, light particles enter the separation mechanism with the airflow. When the components set in the separation mechanism rotate, the particles remaining in the separation mechanism can be scraped off. That is, during the fluidization process, light particles with lower density move with the rising airflow, are guided by the guide plate at the top of the fluidization chamber, and are concentrated into the air inlet pipe; the airflow carrying light particles enters the connecting pipe installed in the sleeve through the air inlet pipe, and can finally be discharged from the exhaust pipe through the separation channel. The light carbon particles can be recovered by the collection device afterward. When particles are attached to the inner wall of the air inlet pipe and the connecting pipe after long-term use, the motor switch installed at the top of the sleeve can be turned on. The motor drives the rotating shaft to rotate inside the sleeve, thereby causing the gear fixed on the side wall of the rotating shaft to drive the gear ring meshing with it to rotate. The gear ring is fixed together with the rotating drum. The gear ring meshes and drives the rotating drum to rotate. The scraper on the rotating drum rotates synchronously along the inner wall of the guide plate, the connecting pipe, and the air inlet pipe, thereby removing the adhering particles and preventing the channel from being blocked.

[0014] (3) The apparatus and method for fluidized bed separation of municipal sludge carbonization products described in this invention: heavy particles move toward the cooling mechanism via the air distribution plate. When the cooling mechanism is started, cold air is introduced into the part of the air chamber to cool the material. That is, heavy impurities with higher density (such as sand particles and metal oxides) move toward the end of the fluidized bed away from the feeding hopper under the action of excitation force and their own gravity. After being combed by the guide rod in the fluidized bed, they are guided into the feeding hopper by the inclined inner wall of the air guide plate. At this time, cold air is introduced into the cooling pipe through the cold air pipe. The cold air is blown toward the heavy particles at the end of the fluidized bed through two sets of inclined air blowing pipes. The cooling is completed during the falling of the particles. The cooled heavy particles fall into the feeding hopper and are finally discharged through the discharge pipe to achieve separation from the light particles.

[0015] (4) The device and method for fluidized bed separation of municipal sludge carbonization products described in this invention, when the air chamber needs to be inspected, can be opened by rotating the inspection mechanism to view the internal components of the air chamber; the sealing mechanism can be removed by rotating to separate the air chamber from the fluidization chamber, thereby allowing the air distribution plate to be cleaned. That is, when the air chamber needs to be inspected, the positioning block is opened by rotating to remove it from the clamping rod, and then the inspection door is pulled away from the air chamber. The inspection door is rotated so that the fixing ring fixed on its side wall rotates along the fixing rod, thereby allowing the air distribution plate to be cleaned. The sealing ring fixed on the upper part of the chamber is in the open state, allowing inspection of the components inside the air chamber. When separating the air chamber from the fluidization chamber, use a tool to rotate the rotating block. The rotating block drives the lead screw fixed at the bottom to rotate along the inner wall of the bracket. The lead screw drives the abutment block to move upward, causing the insertion rod fixed at the bottom of the abutment block to slide out from inside the two base plates fixed on the air chamber and the fluidization chamber. Then rotate the bracket to make it rotate to a position close to the air chamber. At this time, the two base plates lose the limitation of the insertion rod, allowing the air chamber to be separated from the fluidization chamber, thus facilitating the cleaning of the air distribution plate.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8 and Figure 9 As shown, the device for fluidized bed separation of municipal sludge carbonization products according to the present invention includes a vibration isolation spring 1, with a wind chamber 5 fixedly connected to the top of the vibration isolation spring 1; vibrators 2 are fixedly installed on both sides of the wind chamber 5; two maintenance mechanisms 3 and several hot air pipes 10 are installed on the wind chamber 5; an air distribution plate 11 is fixedly installed inside the wind chamber 5; the wind chamber 5 is fixedly connected to a fluidization chamber 6 through a sealing mechanism 7; a cooling mechanism 4 is installed on the wind chamber 5 and the fluidization chamber 6 near the end of the air distribution plate 11; a feeding hopper 8 is connected to the end of the fluidization chamber 6 away from the cooling mechanism 4; and a separation mechanism 9 is fixedly installed at the top of the fluidization chamber 6.

[0021] Specifically, such as Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8As shown, the separation mechanism 9 includes an air inlet pipe 904 and a guide plate 907. Two guide plates 907 are connected internally to the fluidization chamber 6. An air inlet pipe 904 is fixedly installed on each guide plate 907. A sleeve 905 is engaged at one end of the air inlet pipe 904. A connecting pipe 903 is engaged inside the other sleeve 905. The two sleeves 905 are fixedly connected by bolts. A motor 906 is fixedly installed on the sleeve 905 near the connecting pipe 903. The output end of the motor 906 is fixed by a coupling. A rotating shaft 913 is connected, and a gear 912 is fixedly connected to the rotating shaft 913. A gear ring 911 meshes with the gear 912, and a rotating cylinder 909 is fixedly connected to the gear ring 911. The rotating cylinder 909 is rotatably connected to the connecting pipe 903, the air intake pipe 904, and the sleeve 905. A scraper 908 is fixedly connected to the rotating cylinder 909. The gear 912 drives the rotating cylinder 909 fixed on the gear ring 911 to rotate, and the scraper 908 on the rotating cylinder 909 rotates synchronously along the inner wall of the guide plate 907, the connecting pipe 903, and the air intake pipe 904. It can remove adhering particles and prevent channel blockage; the scraper 908 is rotatably connected to the connecting pipe 903, the air inlet pipe 904, and the guide plate 907. A separation channel 902 is fixedly installed at the top of the two connecting pipes 903, and an exhaust pipe 901 is connected to the separation channel 902. The airflow carrying light particles enters the connecting pipe 903 installed inside the sleeve 905 through the air inlet pipe 904, and finally exits through the exhaust pipe 901 via the separation channel 902. The light carbon particles can be subsequently recovered by a collection device; the sleeve 905 has teeth... Two washers 910 are symmetrically installed on the ring 911. The connecting pipe 903 and the air inlet pipe 904 are in contact with the washers 910. The inner diameter of the washers 910 is larger than the diameter of both ends of the rotating drum 909. The guide plate 907 is set with a conical structure. During fluidization, the light particles with lower density move with the rising airflow and are guided by the guide plate 907 at the top of the fluidization chamber 6 and concentrated into the air inlet pipe 904. The scraper 908 is set with an inclined structure near the guide plate 907. The toothed ring 911 and the rotating shaft 913 are rotatably connected to the sleeve 905.

[0022] Specifically, such as Figure 3 , Figure 4 and Figure 9As shown, the air distribution plate 11 has several sets of vertical through holes 12 in its central part, and several sets of inclined through holes 13 at both ends of the air distribution plate 11. The two sets of inclined through holes 13 have different inclination directions. Hot air at a preset temperature is introduced into the air chamber 5 through the hot air pipe 10. After being buffered in the air chamber 5, the hot air enters the fluidization chamber 6 through the vertical through holes 12 and inclined through holes 13 of the air distribution plate 11. The vertical through holes 12 in the central area form a uniform upward airflow, so that the material as a whole is in a fluidized state. The inclined through holes 13 at both ends of the air distribution plate 11 generate lateral airflow, which pushes the edge material to converge towards the center of the fluidization chamber 6, thereby avoiding local accumulation of material and enhancing material mixing and dispersion.

[0023] Specifically, such as Figure 1 As shown, the maintenance mechanism 3 includes a fixed rod 301 and a fixed ring 302. Two fixed rods 301 are fixedly connected to the side of the air chamber 5 away from the hot air duct 10. A fixed ring 302 is rotatably mounted on the fixed rod 301. An inspection door 303 is fixedly connected to the fixed ring 302. A sealing ring 306 is fixedly connected to the part of the air chamber 5 near the inspection door 303. The inspection door 303 and the sealing ring 306 are engaged. A locking rod 304 is fixedly connected to the part of the air chamber 5 away from the fixed rod 301. The inspection door 303 and the locking rod 304 are connected together. The components are connected by a snap-fit ​​mechanism. A positioning block 305 is threaded onto the locking rod 304. Rotating the positioning block 305 removes it from the locking rod 304. Then, the inspection door 303 is pulled away from the air chamber 5. Rotating the inspection door 303 causes the fixing ring 302 fixed on its side wall to rotate along the fixing rod 301, thereby opening the sealing ring 306 fixed on the air chamber 5, allowing inspection of the components inside the air chamber 5. The inner diameter of the inspection door 303 is equal to the diameter of the sealing ring 306, and the positioning block 305 abuts against the top of the fixing ring 302.

[0024] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the cooling mechanism 4 includes a cooling pipe 401 and a blower pipe 408. The cooling pipe 401 is fixedly installed on the part of the fluidization chamber 6 away from the feeding hopper 8. An installation block 405 is fixedly connected to the cooling pipe 401, and the installation block 405 is fixedly connected to the fluidization chamber 6. A cold air pipe 402 is connected to the cooling pipe 401. Two sets of blower pipes 408 are symmetrically fixedly connected to the cooling pipe 401. Several guide rods 407 are fixedly installed at equal intervals on the fluidization chamber 6. Under the action of vibration force and their own gravity, heavy impurities with higher density (such as sand particles and metal oxides) move towards the end of the fluidization chamber 6 away from the feeding hopper 8. After being combed by the guide rods 407 in the fluidization chamber 6, they are then guided by the inclined inner wall of the air guide plate 406. The material is fed into the hopper 403. A guide plate 406 is fixedly connected to the part of the fluidization chamber 6 near the cooling pipe 401 and the guide rod 407. The hopper 403 is fixedly installed in the part of the air chamber 5 near the guide plate 406. A discharge pipe 404 is fixedly connected to the bottom of the hopper 403. Cold air is introduced into the cooling pipe 401 through the cold air pipe 402. The cold air is blown towards the heavy particles at the end of the fluidization chamber 6 through two sets of inclined air blowers 408, and the particles are cooled during the falling process. The cooled heavy particles fall into the hopper 403 and are finally discharged through the discharge pipe 404, thus achieving separation from the light particles. The two sets of air blowers 408 are inclined, and the hopper 403 and the guide plate 406 are both inclined structures.

[0025] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the sealing mechanism 7 includes a base plate 701 and insertion holes 708. The top of the air chamber 5 and the bottom of the fluidizing chamber 6 are both fixedly connected to the base plate 701. The base plate 701 has several sets of insertion holes 708. Several sets of connecting shafts 704 are fixedly connected to the bottom of the base plate 701 near the air chamber 5. A bracket 703 is rotatably mounted on the connecting shaft 704. A lead screw 707 is threaded onto the bracket 703. A rotating block 702 and a stop block 706 are fixedly mounted at both ends of the lead screw 707, respectively. An insertion rod 705 is fixedly connected to the stop block 706. The insertion rod 705 is connected to the two base plates 701. The interlocking connection is achieved by rotating the rotating block 702. The rotating block 702 drives the screw 707, which is fixed at the bottom, to rotate along the inner wall of the bracket 703. The screw 707 drives the abutment block 706 to move upward, so that the insertion rod 705, which is fixed at the bottom of the abutment block 706, slides out from the two base plates 701 fixed on the air chamber 5 and the fluidization chamber 6. Then, by rotating the bracket 703, the bracket 703 can be rotated to a position close to the air chamber 5. At this time, the two base plates 701 lose the limitation of the insertion rod 705, and the air chamber 5 and the fluidization chamber 6 can be separated, which facilitates the cleaning of the air distribution plate 11. The abutment block 706 abuts against the top of the base plate 701 near the fluidization chamber 6.

[0026] Specifically, a method for fluidized bed separation of municipal sludge carbonization products includes the following steps: S1: First, the carbonized sludge products to be sorted are fed into the fluidization chamber 6 through the feeding hopper 8. The vibrator 2 is started, and then hot air is introduced into the air chamber 5 through the hot air pipe 10. The hot air can enter the fluidization chamber 6 through the vertical through hole 12 and the inclined through hole 13 set in the air distribution plate 11 to fluidize the material. S2: Furthermore, during the fluidization process, light particles enter the separation mechanism 9 with the airflow. When the components installed in the separation mechanism 9 rotate, the particles remaining in the separation mechanism 9 can be scraped off. S3: Then the heavy particles move towards the cooling mechanism 4 via the air distribution plate 11. When the cooling mechanism 4 is started, cold air is introduced into the part of the air chamber 5 to cool the material. S4: When the air chamber 5 needs to be inspected, rotate and open the inspection mechanism 3 to view the internal components of the air chamber 5.

[0027] In use, the municipal sludge carbonization products (containing a mixture of carbon particles, inorganic impurities, etc.) to be sorted are first fed into the fluidization chamber 6 at a uniform speed through the feeding hopper 8. The material initially accumulates on the side of the fluidization chamber 6 closest to the feeding hopper 8. Then, the vibrators 2 fixed on both sides of the air chamber 5 are activated. The vibration generated by the vibrators 2 is transmitted to the fluidization chamber 6 through the air chamber 5, which initially loosens the material in the fluidization chamber 6 and reduces particle agglomeration. Next, hot air at a preset temperature is introduced into the air chamber 5 through the hot air pipe 10. After being buffered in the air chamber 5, the hot air enters the fluidization chamber 6 through the vertical through holes 12 and inclined through holes 13 of the air distribution plate 11. The vertical through holes 12 in the central area form a uniform upward airflow, making the material fluidized as a whole. The inclined through holes 13 at both ends of the air distribution plate 11 generate lateral airflow, pushing the edge material to converge towards the center of the fluidization chamber 6, thereby avoiding local accumulation of material and enhancing material mixing and dispersion. During fluidization, the lighter particles with lower density move with the rising airflow and are guided by the guide plate 907 at the top of the fluidization chamber 6, concentrating into the inlet pipe 904. The airflow carrying the lighter particles enters the connecting pipe 903 installed inside the sleeve 905 through the inlet pipe 904, and finally can be discharged from the exhaust pipe 901 through the separation channel 902. The lighter carbon particles can be recovered by a collection device. When particles adhere to the inner walls of the inlet pipe 904 and the connecting pipe 903 after long-term use, the sleeve 905 can be opened. 5. The motor 906 installed at the top switches the motor 906 to drive the rotating shaft 913 to rotate inside the sleeve 905, which in turn causes the gear 912 fixed on the side wall of the rotating shaft 913 to drive the gear ring 911 that meshes with it to rotate. The gear ring 911 is fixed together with the rotating drum 909. The meshing of the gear ring 911 drives the rotating drum 909 to rotate. The scraper 908 on the rotating drum 909 rotates synchronously along the inner wall of the guide plate 907, the connecting pipe 903, and the air inlet pipe 904, which can remove the adhering particles and prevent the channel from being blocked. Heavy impurities with higher density (such as sand particles and metal oxides) move towards the end of the fluidization chamber 6 away from the feed hopper 8 under the action of excitation force and their own gravity. After being combed by the guide rod 407 in the fluidization chamber 6, they are guided into the feed hopper 403 by the inclined inner wall of the air guide plate 406. At this time, cold air is introduced into the cooling pipe 401 through the cold air pipe 402. The cold air is blown towards the heavy particles at the end of the fluidization chamber 6 through two sets of inclined air blowing pipes 408, and the particles are cooled during the falling process. The cooled heavy particles fall into the feed hopper 403 and are finally discharged through the discharge pipe 404, realizing the separation from the light particles. When maintenance is required inside the air chamber 5, rotate and open the positioning block 305 to remove it from the clamping rod 304. Then, pull the inspection door 303 away from the air chamber 5 and rotate the inspection door 303 so that the fixing ring 302 fixed to its side wall rotates along the fixing rod 301, thereby opening the sealing ring 306 fixed on the air chamber 5, allowing inspection of the components inside the air chamber 5. When separating the air chamber 5 from the fluidization chamber 6, use a tool to rotate the rotating block 702. 2. The screw 707 fixed at the bottom is rotated along the inner wall of the bracket 703. The screw 707 drives the block 706 to move upward, so that the insertion rod 705 fixed at the bottom of the block 706 slides out from the two base plates 701 fixed on the air chamber 5 and the fluidization chamber 6. Then, the bracket 703 is rotated to a position close to the air chamber 5. At this time, the two base plates 701 lose the limitation of the insertion rod 705, and the air chamber 5 and the fluidization chamber 6 can be separated, which makes it easier to clean the air distribution plate 11.
