Description

Technical Field

[0001] This invention relates to the field of RTO regenerators, and more specifically, to a device for preventing particulate matter blockage in RTO regenerators. Background Technology

[0002] An RTO (Regenerative Thermal Oxidizer) chamber, also known as a waste gas incinerator, is a device that uses the heat generated by the combustion of auxiliary fuel to raise the temperature of combustible and harmful gases to the reaction temperature, thereby causing oxidation and decomposition. The heat from the combustion waste gas is then stored and recovered. Generally, during the waste gas transportation process, a particulate filter structure is installed to prevent particulate matter from entering the equipment and to filter out the particles in the waste gas.

[0003] Existing particulate filter structures are prone to clogging after a period of use, which affects the efficiency of exhaust gas introduction. This requires staff to clean the filter structure regularly, but exhaust gas cannot be transported during the cleaning process, thus affecting the working efficiency of the RTO heat storage chamber.

[0004] Existing filter devices, such as patented technology CN206778706U, involve a dust removal device for printing machinery. When the printing machinery body 1 is working, the dust removal device is activated. The fan generates centrifugal force to draw dust-laden gas inside the printing machinery body 1 into an electrostatic precipitator through the dust-laden gas inlet. The electrostatic precipitator is powered on, and the dust in the airflow becomes charged and separates from the airflow under the action of the corona electrode. The dust is adsorbed onto the collecting electrode. After the operation is completed, the power is cut off, and the dust falls into the ash hopper and is discharged. During cleaning, the top cover can be opened to clean the inside of the electrostatic precipitator. Although this design can achieve electrostatic adsorption and cleaning of the dust falling into the ash hopper, it requires opening from the outside and using an external cleaning device, such as a brush, to clean the dust, making it inconvenient to operate. Other designs where the dust falls directly into the ash hopper are prone to dust leakage. Summary of the Invention

The device features a filtration mechanism that can be rotated and adjusted, and several piezoelectric ceramic plates are installed on the filtration mechanism. The vibration generated by the piezoelectric ceramic plates dislodges particles from the filtration mechanism, thereby cleaning the filtration mechanism. The dislodged particles are then recovered by the suction force generated by a fan, avoiding the need for manual cleaning and preventing clogging from affecting the efficiency of the introduced exhaust gas.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a particulate matter clogging prevention device for an RTO regenerator, comprising a gas guide pipe and an air inlet pipe fixedly installed at one end of the gas guide pipe, wherein a filter mechanism for filtering particles in exhaust gas is provided inside the gas guide pipe, the filter mechanism comprising a mounting frame and a filter frame fixedly installed inside the mounting frame, wherein a plurality of piezoelectric ceramic plates are fixedly installed around the perimeter of the filter frame, and one end of the mounting frame is movably connected to the gas guide pipe;

[0008] The air intake pipe has an air guide mechanism for inputting exhaust gas at one end.

[0009] The bottom end of the air duct is equipped with a recovery mechanism for particle recovery.

[0010] In response to the start of the filter cleaning operation, the air guiding mechanism performs electromagnetic transmission to close the exhaust gas transmission channel and drives the filter frame to rotate 90° to the horizontal via a motor. In response to the rotation of the filter frame, the valve plate is triggered to rotate to open the bottom filter recovery channel.

[0011] Furthermore, the recycling mechanism includes a bottom pipe fixedly installed at the bottom end of the air guide pipe and a fan fixedly installed at the bottom end of the bottom pipe, with the top end of the bottom pipe connected to the air guide pipe.

[0012] Furthermore, a motor is fixedly installed on one side of the outer surface of the air guide tube, and one end of the output shaft of the motor is fixedly connected to the mounting bracket. The mounting bracket is rotatably connected to the air guide tube through the motor.

[0013] Furthermore, the limiting mechanism includes a mounting tube fixedly installed on one side of the outer surface of the air guide tube above the motor. A limiting rod is provided inside the mounting tube, and one end of the limiting rod passes through the outer surface of the air guide tube and is inserted into a limiting groove opened on the outer surface of one end of the mounting bracket.

[0014] Furthermore, a stop block is integrally connected to the outer surface of the limiting rod, a first return spring is sleeved on one side of the outer surface of the limiting rod located on the stop block, and a first electromagnet is sleeved on one end of the outer surface of the limiting rod located on the stop block. The first electromagnet is fixedly installed inside one end of the mounting tube.

[0015] Furthermore, a valve seat is fixedly installed inside the bottom tube, a valve plate is provided inside the valve seat, a sealing ring is sleeved on the outer surface of the valve plate, and a transmission mechanism is provided between the valve plate and the mounting bracket.

[0016] Furthermore, the transmission mechanism includes a second transmission wheel fixedly connected to the other end of the mounting bracket, a rotating shaft fixedly mounted on one end of the valve plate, a first transmission wheel fixedly connected to one end of the rotating shaft, and the first transmission wheel and the second transmission wheel being connected by a sleeved transmission belt.

[0018] Furthermore, the air guiding mechanism includes an air supply pipe fixed inside the connecting seat and an inner pipe disposed inside the air supply pipe, wherein the inner pipe is inserted into the partition of the air supply pipe. The inner pipe is slidably connected to the air supply pipe.

[0019] Furthermore, a retaining ring is fixedly installed at one end of the inner tube outside the gas transmission pipe, a second return spring is sleeved on the outer surface of the gas transmission pipe and the inner tube, and a second electromagnet is fixedly installed at the end of the gas transmission pipe partition away from the retaining ring.

[0020] The technical effects and advantages of this invention are as follows:

[0021] The present invention features a filter mechanism that can be flipped and adjusted, and several piezoelectric ceramic plates are installed on the filter mechanism. The vibration generated by the piezoelectric ceramic plates can dislodge particles from the filter mechanism, thereby cleaning the filter mechanism. The dislodged particles are then recycled by the suction generated by the fan, avoiding the need for manual cleaning and preventing blockages that could affect the efficiency of the exhaust gas intake.

[0022] This invention incorporates a gas guiding mechanism with a sealing mechanism at one end. When waste gas is input, the sealing mechanism opens to transport waste gas. When the filter needs cleaning, the sealing mechanism closes the gas guiding mechanism, preventing waste gas from being introduced during cleaning and preventing particulate matter from entering the RTO heat storage chamber, thus increasing the effectiveness of the gas guiding mechanism.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] according to Figure 1-5 The device shown is an anti-particulate matter clogging device for an RTO regenerator, including a gas guide pipe 1 and an air inlet pipe 2 fixedly installed at one end of the gas guide pipe 1. The gas guide pipe 1 is provided with a filter mechanism for filtering particles in the exhaust gas. The filter mechanism includes a mounting frame 13 and a filter frame 14 fixedly installed inside the mounting frame 13. Several piezoelectric ceramic plates 15 are fixedly installed around the frame of the filter frame 14. One end of the mounting frame 13 is movably connected to the gas guide pipe 1.

[0034] A limiting mechanism for limiting and fixing the mounting bracket 13 is provided on one outer surface of the air duct 1.

[0035] The air intake pipe 2 has an air guide mechanism for inputting exhaust gas at one end.

[0036] The bottom end of the air duct 1 is provided with a recovery mechanism for recovering particles.

[0037] In response to the start of the filter cleaning operation, the air guiding mechanism performs electromagnetic transmission to close the exhaust gas transmission channel and drives the filter frame 14 to rotate 90° to the horizontal via a motor. In response to the rotation of the filter frame 14, the valve plate 37 is triggered to rotate to open the bottom filter recovery channel.

[0038] Furthermore, the recycling mechanism includes a bottom pipe 3 fixedly installed at the bottom end of the air guide pipe 1 and a fan 31 fixed at the bottom end of the bottom pipe 3. The top end of the bottom pipe 3 is connected to the air guide pipe 1. When the piezoelectric ceramic plates 15 around the filter frame 14 are activated, the particles on the filter screen are vibrated and detached by the vibration generated by the piezoelectric ceramic plates 15. At the same time, the fan 3 at the bottom end of the bottom pipe 3 will be activated to suck the detached particles downward for recycling.

[0039] Furthermore, a motor 12 is fixedly installed on one side of the outer surface of the air guide tube 1. One end of the output shaft of the motor 12 is fixedly connected to the mounting frame 13. The mounting frame 13 is rotatably connected to the air guide tube 1 through the motor 12. When the motor 12 is started, the mounting frame 13 is flipped to one side by the motor 12, and the filter screen on the fallen mounting frame 13 corresponds to the bottom end of the bottom tube 3.

[0040] Furthermore, the limiting mechanism includes a mounting tube 11 fixedly installed on one side of the outer surface of the air duct 1 above the motor 12. A limiting rod 16 is provided inside the mounting tube 11. One end of the limiting rod 16 passes through the outer surface of the air duct 1 and is inserted into a limiting groove opened on one side of the outer surface of the mounting frame 13. When the first electromagnet 19 inside the mounting tube 11 is activated, the stop block 17 is attracted by the magnetic force of the first electromagnet 19, which will drive the limiting rod 16 to move outward, so that one end of the limiting rod 16 disengages from the limiting groove on one side of the mounting frame 13.

[0041] Furthermore, a stop block 17 is integrally connected to the outer surface of the limiting rod 16. A first return spring 18 is sleeved on one side of the outer surface of the limiting rod 16 located on the stop block 17. A first electromagnet 19 is sleeved on one end of the outer surface of the limiting rod 16 located on the stop block 17. The first electromagnet 19 is fixedly installed inside one end of the mounting tube 11. When the limiting rod 16 moves outward, it will squeeze the first return spring 18 through the stop block 17.

[0042] Furthermore, a valve seat 36 is fixedly installed inside the bottom tube 3, and a valve plate 37 is provided inside the valve seat 36. A sealing ring is sleeved on the outer surface of the valve plate 37. A transmission mechanism is provided between the valve plate 37 and the mounting frame 13. The transmission mechanism includes a second transmission wheel 35 fixedly connected to the other end of the mounting frame 13. A rotating shaft 33 is fixedly installed at one end of the valve plate 37, and a first transmission wheel 32 is fixedly connected to one end of the rotating shaft 33. The first transmission wheel 32 and the second transmission wheel 35 are connected by a transmission belt 34. When the mounting frame 13 is flipped down, it will drive the second transmission wheel 35 at one end to rotate. The second transmission wheel 35 drives the first transmission wheel 32 to rotate through the transmission belt 34, and then drives the valve plate 37 inside the valve seat 36 to rotate through the rotating shaft 33 at one end, thereby opening the bottom tube 3.

[0043] The specific implementation method is as follows: During use, exhaust gas is introduced through one end of the intake pipe 2, and then the particles in the exhaust gas are filtered through the filter screen inside the guide pipe 1 before being introduced into the RTO heat storage chamber. When it is necessary to clean the filter screen inside the mounting frame 13, the first electromagnet 19 inside the mounting pipe 11 is activated first. The stop block 17 is attracted by the magnetic force of the first electromagnet 19, which will drive the limit rod 16 to move outward, so that one end of the limit rod 16 disengages from the limit groove on one side of the mounting frame 13, releasing the limit on the mounting frame 13. Then, the motor 12 is activated, which drives the mounting frame 13 to flip to one side. The filter screen on the fallen mounting frame 13 corresponds to the bottom end of the bottom pipe 3. During the process of the mounting frame 13 flipping and falling, it will drive one end of the filter screen to flip to one side. The second drive wheel 35 rotates, driving the first drive wheel 32 to rotate via the drive belt 34. This rotation, in turn, drives the valve plate 37 inside the valve seat 36 to rotate via the shaft 33 at one end, opening the bottom pipe 3. Next, the piezoelectric ceramic plates 15 around the filter frame 14 are activated, vibrating to dislodge particles from the filter screen. Simultaneously, the fan 3 at the bottom of the bottom pipe 3 starts, drawing the dislodged particles downwards for recycling. After cleaning the filter screen, the motor 12 drives the mounting bracket 13 to reset. During this reset process, the valve plate 37 is reset via a transmission mechanism on one side, closing the bottom pipe 3 and preventing exhaust gas from entering during use. The limit rod 16 moves outwards during this process. The first return spring 18 will be squeezed by the stop block 17. After the squeezing is completed, the mounting bracket 13 will be reset and the first electromagnet 19 will be closed. The first return spring 19 will push the limit rod 16 inward and insert one end of the limit rod 16 into the limit groove to limit the mounting bracket 13.

[0044] according to Figure 6-8The device shown is for preventing particulate matter blockage in an RTO regenerator. Further, a connecting seat 21 is fixedly installed at one end of the air inlet pipe 2, and a connecting pipe is fixedly installed on the outer surface of the connecting seat 21. The connecting pipe is connected to one end of the air guiding mechanism. An inner frame 22 is fixedly installed at one end of the air inlet pipe 2. Before use, it needs to be connected to the exhaust gas conveying mechanism through one end of the connecting seat 21. Exhaust gas enters from the gas conveying pipe 23 and is introduced into the air inlet pipe 2 through one end of the inner pipe 25.

[0045] Furthermore, the air guiding mechanism includes an air supply pipe 23 fixed inside the connecting seat 21 and an inner tube 25 disposed at one end of the air supply pipe 23. The inner tube 25 is inserted into the partition at one end of the air supply pipe 23. The inner tube 25 is slidably connected to the air supply pipe 23, and the exhaust gas is introduced into the intake pipe 2 through one end of the inner tube 25. During the process of introducing exhaust gas, the second electromagnet 27 is in the activated state. The inner tube 25 is attracted by the magnetic force of the second electromagnet 27 and moves to one side along the air supply pipe 23, causing one end of the inner tube 25 to detach from the surface of the inner frame 22, thereby opening one end of the inner tube 25 to facilitate the introduction of exhaust gas.

[0046] Furthermore, a retaining ring 26 is fixedly installed at one end of the inner tube 25, and a second return spring 24 is sleeved on the outer surface of the air supply pipe 23 and the inner tube 25. A second electromagnet 27 is fixedly installed at one end of the air supply pipe 23. When the inner tube 25 moves to one side, the retaining ring 26 at one end will squeeze the second return spring 24. During the cleaning of the filter screen, the second electromagnet 27 needs to be turned off. When the inner tube loses the magnetic attraction of the second electromagnet 27, the second return spring 24 will push the retaining ring 26 to reset the inner tube 25.

[0047] The specific implementation method is as follows: Before use, it needs to be connected to the exhaust gas conveying mechanism through the connecting seat 21. Exhaust gas enters from the gas conveying pipe 23 and is introduced into the intake pipe 2 through one end of the inner tube 25. During the process of introducing exhaust gas, the second electromagnet 27 is in the activated state. The inner tube 25 is attracted by the magnetic force of the second electromagnet 27 and will move to one side along the gas conveying pipe 23, so that one end of the inner tube 25 is separated from the surface of the inner frame 22, thereby opening one end of the inner tube 25 to facilitate the introduction of exhaust gas. During the process of the inner tube 25 moving to one side, the retaining ring 26 at one end will squeeze the second return spring 24. During the cleaning of the filter screen, the second electromagnet 27 needs to be closed. When the inner tube loses the magnetic attraction of the second electromagnet 27, the second return spring 24 will push the retaining ring 26 to reset the inner tube 25. After reset, one end of the inner tube 25 will be attached to the surface of the inner frame 22, thereby closing one end of the inner tube 25 and preventing the gas conveying pipe 23 from continuing to convey exhaust gas.

[0048] When performing specific tasks, refer to the instruction manual appendix. Figure 1-5During use, exhaust gas is introduced through one end of the intake pipe 2, and then the particles in the exhaust gas are filtered through the filter screen inside the air guide pipe 1 before being introduced into the RTO heat storage chamber. When it is necessary to clean the filter screen inside the mounting frame 13, the motor 12 is started, and the motor 12 drives the mounting frame 13 to flip to one side. The filter screen on the fallen mounting frame 13 corresponds to the bottom end of the bottom pipe 3. During the process of the mounting frame flipping down, the second transmission wheel 35 at one end will rotate. The second transmission wheel 35 drives the first transmission wheel 32 to rotate through the transmission belt 34, and then drives the valve plate 37 in the valve seat 36 to rotate through the rotating shaft 33 at one end, thereby opening the bottom pipe 3. Then, the piezoelectric ceramic plates 15 around the filter frame 14 are activated. The vibration generated by the piezoelectric ceramic plates 15 vibrates and dislods the particles on the filter screen. At the same time, the fan 3 at the bottom end of the bottom pipe 3 will be started to suck the dislodged particles downward for recycling.

[0049] Refer to the instruction manual appendix Figure 6-8 Before use, it needs to be connected to the exhaust gas conveying mechanism through the connecting seat 21. Exhaust gas enters from the gas delivery pipe 23 and is introduced into the intake pipe 2 through one end of the inner tube 25. During the process of introducing exhaust gas, the second electromagnet 27 is in the activated state. The inner tube 25 is attracted by the magnetic force of the second electromagnet 27 and will move to one side along the gas delivery pipe 23, so that one end of the inner tube 25 is separated from the surface of the inner frame 22, thereby opening one end of the inner tube 25 to facilitate the introduction of exhaust gas. During the process of the inner tube 25 moving to one side, the retaining ring 26 at one end will squeeze the second return spring 24. During the cleaning of the filter screen, the second electromagnet 27 needs to be closed. When the inner tube loses the magnetic attraction of the second electromagnet 27, the second return spring 24 will push the retaining ring 26 to reset the inner tube 25. After reset, one end of the inner tube 25 will be attached to the surface of the inner frame 22, thereby closing one end of the inner tube 25 and preventing the gas delivery pipe 23 from continuing to transport exhaust gas.

[0050] In the above process, in response to the start of the filter cleaning operation, the air guiding mechanism performs electromagnetic transmission to close the exhaust gas transmission channel and drives the filter frame (14) to rotate 90° to the horizontal via a motor. In response to the rotation of the filter frame (14), the mechanical mechanism triggers the rotation of the valve plate (37) to open the bottom filter recovery channel.
