Description

Technical Field

[0001] The present invention relates to the technical field of waste heat recovery, and particularly to an energy-saving kiln flue gas waste heat recovery and utilization device and a recovery method thereof. Background Technique

[0002] In industrial production, kilns are important heat energy equipment and are widely used in industries such as cement, metallurgy, and chemical industry. However, during the operation of kilns, a large amount of high-temperature flue gas is generated. These flue gases not only contain a large amount of heat energy but also carry dust and harmful substances. If these flue gases are directly discharged into the atmosphere, it will not only cause waste of energy but also cause serious environmental pollution. Therefore, how to efficiently recover and utilize the waste heat in kiln flue gas while reducing the emission of dust and harmful substances has become an urgent problem to be solved in current industrial production.

[0003] Traditional kiln flue gas waste heat recovery technologies mainly include equipment such as waste heat boilers and heat exchangers. These equipment can achieve the recovery of flue gas waste heat to a certain extent, but there are still the following problems: Low heat recovery efficiency: When traditional equipment recovers the waste heat of flue gas, there is a large amount of heat loss, resulting in low heat recovery efficiency and inability to fully utilize the heat energy in the flue gas.

[0004] Incomplete dust treatment: Dust in the flue gas is often difficult to be completely separated during the recovery process, resulting in problems such as equipment blockage and crusting, affecting the normal operation of the equipment and even reducing the quality of products such as cement.

[0005] High equipment maintenance cost: Due to the accumulation of dust and harmful substances, the equipment needs to be frequently maintained and cleaned, increasing production costs and time.

[0006] Serious environmental pollution: When traditional technologies treat flue gas, it is difficult to effectively remove the harmful substances in it, resulting in the continuous existence of environmental pollution problems. Summary of the Invention

[0016] Further, a method for recovering waste heat from high-temperature flue gas of a cement kiln includes the following steps: S1: First, insert the probe at the bottom of the intake pipe into the cement kiln for data collection, and then connect the outlet pipe to the equipment for waste heat power generation; S2: Start the second blower. When the second blower is working, it will appropriately introduce natural wind through the intake pipe to supplement the oxygen content; S3: Then start the first blower. The first blower can transport the flue gas into the high-temperature dust collector. After the dust collection of the high-temperature dust collector, it will be transported through the outlet pipe to the waste heat power generation equipment for waste heat recovery.

[0017] The present invention has the following beneficial effects: 1. In the present invention, first, the probe at the bottom of the intake pipe is inserted into the cement kiln for data collection. Then, the outlet pipe is connected to the equipment for waste heat power generation, and the second blower is started. When the second blower is operating, it will appropriately introduce natural air through the intake pipe to supplement the oxygen content. Then, the second blower will transport the flue gas through the intake pipe to the cyclone. After that, the gas containing smoke will rotate through the spiral groove inside the cyclone. By using the centrifugal force generated by the rotating dust-containing gas, large particles of dust can be separated from the gas stream. Then, the first blower is started. The suction force generated by the first blower will drive the fan blades to rotate, which in turn can drive the gas inside the cyclone to rotate. After that, the separated gas and a small amount of dust will enter the recovery box through the outlet pipe. Through the filtration of the filter plate inside the recovery box, powder-gas separation is carried out. Then, the dust filtered out by the filter plate will fall into the ash bin for collection. The collected dust can be used as ingredients or for other purposes, which can effectively reduce the amount of chlorine in the ash residue and the amount of chlorine in the RDF introduced into the cement kiln, preventing the recovery box or other systems from scaling and blocking. After that, the high-temperature gas is filtered through the high-temperature dust collector and finally used for waste heat power generation. The heat loss of this device is smaller than that of other processes, and the heat recovery efficiency is high. It not only reduces the impact of a large amount of chloride ions in the flue gas on the cement kiln system but also ensures the quality of the cement output, with a high heat recovery efficiency.

[0018] 2. In the present invention, after the first blower is started, the first blower can extract and transport the flue gas into the recovery box. When the gas is transported into the recovery box, it will be pressurized by the first blower, thus accelerating the flow rate of the flue gas. At this time, the gas with too fast a flow rate will blow towards the rotating paddle at one end of the middle shaft and cause it to rotate. When the rotating paddle rotates and drives the middle shaft to rotate, the rotating middle shaft will drive the first rotating disk to rotate. When the first rotating disk rotates, it will contact the spring plate through the special-shaped groove on the first rotating disk. When the protruding part of the special-shaped groove contacts the spring plate, it will cause the spring plate to move towards the middle shaft. When the spring plate moves, it will pull the fixed rod downward through the straight groove block. When the fixed rod moves downward, it will pull the first connecting plate to move synchronously on both sides of the inclined plate. When the first connecting plate moves along with the movement of the fixed rod, it will cause the middle parts of multiple inclined plates to rotate slightly in the hollow groove. When the inclined plates rotate in the hollow groove, they will guide the gas transported into the recovery box by the first blower, so that the gas can be evenly distributed inside the recovery box, avoiding the uneven gas flow when passing through the filter plate for filtration, which may cause premature blockage or damage to some areas of the filter plate, thus affecting the subsequent waste heat recovery efficiency.

[0019] 3. In the present invention, when the intermediate shaft rotates, it drives the rotating roller to rotate through the second connecting plate. When the rotating roller rotates, the two L-shaped rods are driven by the elliptical groove on the second rotating disc to move relatively on the first sliding plate on the rectangular frame. When the first sliding plate moves, one end of the rhombic plate slides on the side wall of the cross plate. When the extended end of the rhombic plate slides on the side wall of the cross plate, the rhombic plate rotates due to friction. When the rhombic plate rotates, it squeezes the second sliding plate, causing the second sliding plate to slide on the first guide rod. When the second sliding plate slides upward, the rolling disc contacts the L-shaped plate and rotates during the upward movement of the second sliding plate. When the rolling disc rotates, it drives the pull rod to rotate through the short plate. And when the pull rod rotates, it slides forward on the hollow plate. When the pull rod rotates along with the short plate, the cleaning plate slides back and forth on the slider, and at the same time, the slider slides up and down on the slide rail. At this time, the sliding cleaning plate contacts the filter plate. Then, as the second sliding plate moves, the short plate enables the pull rod to move on the hollow plate and rotate reciprocally at the same time. When the pull rod rotates, it enables the cleaning plate to drive the slider to slide on the slide rail. The sliding cleaning plate can clean the dust and particles blocking the surface of the filter plate. At the same time, when the pull rod slides forward on the hollow plate along with the rotation of the short plate, the pull rod pushes the first push plate to make the second push plate reciprocate in the hollow frame through the first push plate. When the second push plate moves forward, it squeezes the gas inside the hollow frame. After the gas is squeezed, a fast-flowing air current is generated. At this time, the fast air current sprays onto the surface of the filter plate through the round hole on the right side of the hollow frame. First, it can further remove the residues on the surface of the filter plate, making the filter plate cleaner. Second, the generated air current can form a certain pressure difference inside the filter plate to help discharge the peeled dirt from the filter plate, thereby improving the cleaning efficiency of the cleaning plate for the filter plate.

[0020] 4. In the present invention, when the roller contacts the side wall of the L-shaped plate and rotates as the second sliding plate moves, when the roller rotates, the rotating roller drives the belt to rotate. When the belt rotates, it drives the special-shaped disk to rotate. At this time, the rotating special-shaped disk slides the cylinder in the x-groove on the surface of the rotating shaft. When the cylinder slides in the X-groove, the cylinder forms a squeezing force in the X-groove as the special-shaped disk rotates, causing the rotating shaft to rotate. Then, when the special-shaped disk rotates, it also causes the middle part of the obtuse-angle plate to rotate up and down around the square block through the rotating groove on the special-shaped disk. When the obtuse-angle plate rotates, it drives the sliding shaft to slide up and down while rotating with the rotating shaft inside the rotating shaft. When the rotating shaft drives the sliding shaft to rotate, the sliding shaft drives the vibrating rod to rotate when it rotates. Initially, the two vibrating rods are on the same horizontal line. When the limiting plate rotates, it drives the vibrating rod to rotate towards the filter plate. At this time, the two rotated vibrating rods are in a parallel state. And when the vibrating rod rotates, the vibrating rod knocks on the surface of the filter plate. When the vibrating rod knocks on the filter plate, the vibrating rod moves on the surface of the second guide rod and squeezes the return spring on the disk. When the vibrating rod separates from the filter plate, the elastic force of the return spring on the disk causes the vibrating rod to return to its initial position. When the vibrating rod knocks on the surface of the filter plate, the vibrating rod drives the second disk to slide on the second guide rod and squeezes the first auxiliary spring. And when squeezing the first auxiliary spring, the elastic force of the first auxiliary spring and the pulling force of the second auxiliary spring cause the second disk to vibrate slightly. The vibration can further loosen and remove the stubborn dirt and particles attached to the surface of the filter plate, thereby enhancing the cleaning effect of the cleaning plate, reducing the maintenance frequency, and lowering the maintenance cost and time.

The two L-shaped rods 504 drive the first sliding plate 505 to move relatively on the rectangular frame 506 through the elliptical groove. When the first sliding plate 505 moves, one end of the diamond-shaped plate 605 will slide on the side wall of the cross-shaped plate 303. When the extended end of the diamond-shaped plate 605 slides on the side wall of the cross-shaped plate 303, the diamond-shaped plate 605 will rotate due to the frictional force.

Circular holes are provided in the top and right outer wall of the hollow frame 711. One-way disks 713 are rotatably connected to the inside of the circular holes. When the diamond-shaped plate 605 rotates, it will squeeze the second sliding plate 604, causing the second sliding plate 604 to slide on the first guide rod 601. When the second sliding plate 604 slides upward, the roller 702 will contact the L-shaped plate 603 and rotate during the upward movement of the second sliding plate 604. When the roller 702 rotates, it will drive the pull rod 704 to rotate through the short plate 703. And when the pull rod 704 rotates, it will slide forward on the hollow plate 705. When the pull rod 704 rotates along with the short plate 703, the cleaning plate 708 will slide back and forth on the slider 710, and at the same time, the slider 710 will slide up and down on the slide rail 709. At this time, the sliding cleaning plate 708 will contact the filter plate 304.

[0033] Further, a vibration mechanism 8 is provided on the outer surface of the work box 701. The vibration mechanism 8 includes a belt 801 sleeved and connected on the outer surface between a roller disc 702 inside the work box 701 and a short plate 703. The conveyor belt 801 penetrates through the outer wall of the work box 701 and extends. An irregular-shaped disc 802 is sleeved on the side of the belt 801 away from the roller disc 702. A rectangular plate is sleeved on the outer surface of the irregular-shaped disc 802, and the bottom of the rectangular plate is fixedly connected to the side wall of the work box 701. A rotation groove is formed on the side of the irregular-shaped disc 802 away from the belt 801. Two cylinders 803 are fixedly connected to the outer surface of the irregular-shaped disc 802, and the two cylinders 803 are symmetrically distributed with the irregular-shaped disc 802 as the center. An obtuse plate 804 is slidably connected inside the rotation groove. The middle part of the obtuse plate 804 is rotatably connected to a square block, and the bottom of the square block is fixedly connected to the top outer wall of the work box 701. One end of the obtuse plate 804 away from the irregular-shaped disc 802 is rotatably connected to a sliding shaft 805. A rotating shaft 806 is slidably connected to the outer surface of the sliding shaft 805. An X groove is formed on the outer surface of the rotating shaft 806, and the cylinder 803 is inserted into the X groove. An F plate is sleeved on the outer surface of the rotating shaft 806, and the bottom of the F plate is fixedly connected to the top outer wall of the work box 701. A limiting plate 807 is fixedly connected to the end of the sliding shaft 805 away from the obtuse plate 804. Two guide rods II 808 are fixedly connected to the side of the limiting plate 807 close to the irregular-shaped disc 802. Two discs 809 are slidably connected to the outer surfaces of the two guide rods II 808. An auxiliary spring I is fixedly connected between the two discs 809. Two limiting rods are fixedly connected to the side of the first disc 809 away from the limiting plate 807. The two limiting rods penetrate through the outer wall of the second disc 809 and extend. An auxiliary spring II is fixedly connected to the outer surface of the extended end of the limiting rod. A vibration rod 810 is fixedly connected to the side of the second disc 809 away from the limiting plate 807. When the roller disc 702 contacts the side wall of the L plate 603 and rotates along with the movement of the second sliding plate 604, when the roller disc 702 rotates, the rotating roller disc 702 will drive the belt 801 to rotate. When the belt 801 rotates, it will drive the irregular-shaped disc 802 to rotate. At this time, the rotating irregular-shaped disc 802 will slide the cylinder 803 in the x groove on the surface of the rotating shaft 806. When the cylinder 803 slides in the X groove, the cylinder 803 will form a squeezing force in the X groove along with the rotation of the irregular-shaped disc 802, causing the rotating shaft 806 to rotate. Then, when the irregular-shaped disc 802 rotates, it will also cause the middle part of the obtuse plate 804 to rotate up and down with the square block as the center through the rotation groove on the irregular-shaped disc 802. When the obtuse plate 804 rotates, it will drive the sliding shaft 805 to slide up and down while rotating in the rotating shaft 806 along with the rotation of the rotating shaft 806. When the rotating shaft 806 drives the sliding shaft 805 to rotate, the sliding shaft 805 will drive the vibration rod 810 to rotate when it rotates. In the initial state, the two vibration rods 810 are on the same horizontal line. When the limiting plate 807 rotates, it will drive the vibration rod 810 to rotate towards the filter plate 304.At this time, the two vibrating rods 810 after rotation are in a parallel state. When the vibrating rods 810 rotate, the vibrating rods 810 will strike the surface of the filter plate 304. When the vibrating rods 810 strike the filter plate 304, the vibrating rods 810 will move on the surface of the guide rod two 808 and squeeze the return spring on the disc 809. When the vibrating rods 810 are separated from the filter plate 304, the elastic force of the return spring on the disc 809 will make the vibrating rods 810 return to the initial position.

[0034] During use, first, the probe at the bottom of the air inlet pipe 205 is inserted into the cement kiln for data collection. Then, the air outlet pipe 305 is connected to the equipment for waste heat power generation, and the second blower 206 is started. When the second blower 206 is working, it will appropriately introduce natural wind through the air inlet pipe 207 to supplement the oxygen content. Then, the second blower 206 will transport the flue gas through the air inlet pipe 205 to the cyclone 201. Then, the flue gas-containing gas will rotate through the spiral groove inside the cyclone 201. By using the centrifugal force generated by the rotating dust-containing gas, large-particle dust can be separated from the air flow. Then, the first blower 204 is started. The suction force generated by the first blower 204 will drive the fan blades 202 to rotate, and then drive the gas inside the cyclone 201 to rotate. Then, the separated gas and a small amount of dust will enter the recovery box 301 through the air outlet pipe 203. After being filtered by the filter plate 304 inside the recovery box 301, the powder and gas are separated. Then, the dust filtered out by the filter plate 304 will fall into the ash bin 302 for collection. The collected dust can be used as ingredients or for other purposes, which can effectively reduce the amount of chlorine in the ash slag and the amount of chlorine in the RDF brought into the cement kiln, preventing the recovery box 301 or other systems from being blocked by crusting. Then, after the high-temperature gas is filtered by the high-temperature dust collector, finally, it is used for waste heat power generation. The heat loss of this device is smaller than that of other processes, and the heat recovery efficiency is high. It not only reduces the impact of a large amount of chloride ions in the flue gas on the cement kiln system but also ensures the quality of cement output, with a high heat recovery efficiency.

[0035] After the first fan 204 is started, the first fan 204 can extract the flue gas and convey it into the recovery box 301. When the gas is conveyed into the recovery box 301, it will be pressurized by the first fan 204, thereby accelerating the flow rate of the flue gas. At this time, the gas with too fast flow rate will blow towards the rotating paddle at one end of the intermediate shaft 407 and cause it to rotate. When the rotating paddle rotates and drives the intermediate shaft 407 to rotate, the rotating intermediate shaft 407 will drive the first rotating disk 408 to rotate. When the first rotating disk 408 rotates, it will contact the spring plate 406 through the special-shaped groove on the first rotating disk 408. When the protruding part of the special-shaped groove contacts the spring plate 406, it will cause the spring plate 406 to move towards the intermediate shaft 407. When the spring plate 406 moves, it will pull the fixed rod 405 downward through the straight groove block 409. When the fixed rod 405 moves downward, it will pull the first connecting plate 404 to move synchronously on both sides of the inclined plate 403. When the first connecting plate 404 moves along with the movement of the fixed rod 405, it will cause the middle parts of multiple inclined plates 403 to rotate slightly in the hollow groove 402. When the inclined plates 403 rotate in the hollow groove 402, they will guide the gas conveyed into the recovery box 301 by the first fan 204, so that the gas can be evenly distributed inside the recovery box 301, avoiding that when the gas flows through the filter plate 304 for filtration, the uneven gas may cause some areas of the filter plate 304 to be blocked or damaged prematurely, thus affecting the recovery efficiency of the subsequent waste heat recovery.

[0036] When the intermediate shaft 407 rotates, it will drive the rotating roller 502 to rotate through the second connecting plate 501. When the rotating roller 502 rotates, it will pass through the elliptical groove on the second rotating disk 503, causing the two L-shaped rods 504 sliding in the elliptical groove to drive the movement of the first sliding plate 505. When the first sliding plate 505 moves, it will move on the rectangular frame 506. When the first sliding plate 505 moves, it will slide on the side wall of the cross plate 303 through one end of the diamond plate 605 penetrating the vertical plate 602. When the extended end of the diamond plate 605 slides on the side wall of the cross plate 303, the diamond plate 605 will rotate. When the diamond plate 605 rotates, it will squeeze the second sliding plate 604, causing the second sliding plate 604 to slide on the first guide rod 601. When the second sliding plate 604 slides upward, the rolling disk 702 will contact the L-shaped plate 603 and rotate during the upward movement of the second sliding plate 604. When the rolling disk 702 rotates, it will drive the pull rod 704 to rotate through the short plate 703. And when the pull rod 704 rotates, it will slide forward on the hollow plate 705. When the pull rod 704 rotates along with the short plate 703, the cleaning plate 708 will slide back and forth on the slider 710, and at the same time, the slider 710 will slide up and down on the slide rail 709. At this time, the sliding cleaning plate 708 will contact the filter plate 304. Then, as the second sliding plate 604 moves, the short plate 703 can cause the pull rod 704 to move on the hollow plate 705 while also performing reciprocating rotation. When the pull rod 704 rotates, the cleaning plate 708 can drive the slider 710 to slide on the slide rail 709. The sliding cleaning plate 708 can clean the dust and particles blocking the surface of the filter plate 304. At the same time, when the pull rod 704 slides forward on the hollow plate 705 as it rotates along with the short plate 703, the pull rod 704 will push the second push plate 712 to reciprocate in the hollow frame 711 through the first push plate 706. When the second push plate 712 moves forward, it will squeeze the gas inside the hollow frame 711. After the gas is squeezed, a fast-flowing air current will be generated. At this time, the fast air current will spray onto the surface of the filter plate 304 through the round hole on the right side of the hollow frame 711. First, it can further remove the residues on the surface of the filter plate 304, making the filter plate 304 cleaner. Second, the generated air current can form a certain pressure difference inside the filter plate 304 to help discharge the peeled dirt from the filter plate 304, thereby enhancing the cleaning efficiency of the cleaning plate 708 for the filter plate 304.

[0037] When in contact with the side wall of the L-shaped plate 603 on the rolling disc 702 and rotating as the sliding plate two 604 moves, when the rolling disc 702 rotates, the rotating rolling disc 702 drives the belt 801 to rotate. When the belt 801 rotates, it drives the special-shaped disc 802 to rotate. At this time, the rotating special-shaped disc 802 slides in the x-groove on the surface of the rotating shaft 806 through the cylinder 803. When the cylinder 803 slides in the X-groove, the cylinder 803 forms a squeezing force in the X-groove as the special-shaped disc 802 rotates, causing the rotating shaft 806 to rotate. After that, when the special-shaped disc 802 rotates, it also causes the obtuse-angle plate 804 to rotate up and down around the square block through the rotating groove on the special-shaped disc 802. When the obtuse-angle plate 804 rotates, it drives the sliding shaft 805 to slide up and down while rotating with the rotating shaft 806 inside the rotating shaft 806. When the rotating shaft 806 drives the sliding shaft 805 to rotate, the sliding shaft 805 drives the vibration rod 810 to rotate when it rotates. In the initial state, the two vibration rods 810 are on the same horizontal line. When the limiting plate 807 rotates, it drives the vibration rod 810 to rotate towards the filter plate 304. At this time, the two rotated vibration rods 810 are in a parallel state. And when the vibration rod 810 rotates, the vibration rod 810 knocks on the surface of the filter plate 304. When the vibration rod 810 knocks on the filter plate 304, the vibration rod 810 moves on the surface of the guide rod two 808 and compresses the return spring on the disc 809. When the vibration rod 810 separates from the filter plate 304, the elastic force of the return spring on the disc 809 makes the vibration rod 810 return to the initial position. When the vibration rod 810 knocks on the surface of the filter plate 304, the vibration rod 810 drives the second disc 809 to slide on the guide rod two 808 and compresses the auxiliary spring one. And when compressing the auxiliary spring one, the elastic force of the auxiliary spring one and the pulling force of the auxiliary spring two cause the second disc 809 to vibrate slightly. The vibration can further loosen and remove stubborn dirt and particles attached to the surface of the filter plate 304, thereby enhancing the cleaning effect of the cleaning plate 708, reducing the maintenance frequency, and lowering the maintenance cost and time.
