Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and in particular to a waste gas treatment device with high temperature resistance. Background Technology

[0002] Waste gas treatment, also known as waste gas purification or waste gas treatment, is a core component of air pollution prevention and control. It refers to the use of various technologies, including physical, chemical, and biological methods, to separate, transform, degrade, or recycle pollutants from waste gases containing harmful pollutants generated in industrial production, municipal operations and maintenance, and transportation. This process ensures the waste gas meets national or local air pollutant emission standards while eliminating safety risks such as flammability, explosiveness, and strong corrosion. It also allows for the recovery and reuse of useful components such as waste heat and valuable solvents from the waste gas. The main targets of treatment are particulate pollutants (such as particles, smoke, droplets, and fine particulate matter) and gaseous pollutants (such as volatile organic compounds). The particulate matter is mainly classified into two categories: particulate matter, sulfur dioxide, nitrogen oxides, acid and alkali waste gas, and malodorous substances. Correspondingly, particulate pollutant control technology systems such as filtration dust removal, mechanical dust removal, wet dust removal, and electrostatic dust removal have been formed, as well as gaseous pollutant purification technology routes such as absorption, adsorption, combustion, and biological methods. A complete waste gas treatment system usually follows the process flow of gas collection, front-end pretreatment, core main purification, and deep treatment to achieve standard emission. Filter plates with mesh holes are mostly arranged in the front-end pretreatment stage to intercept large particles and protect the precision processing components at the back end. Bag filters and other equipment are often used as the core main purification unit to achieve efficient filtration of particulate matter.

[0003] A search revealed Chinese patent document CN210584121U, which discloses an air filter with an easily replaceable perforated plate. The filter includes: a housing with an internal cavity and a cover plate fixed to its surface; a U-shaped fixing plate fixed inside the housing; six perforated plate fixing structures connected to the surface of the fixing plate; and a perforated plate fixed to the front surface of the fixing plate. An adjusting plate is movably connected to the back of the cover plate. Both the cover plate and the adjusting plate have several air inlets. A downwardly recessed groove is provided at the top of the cover plate, and an adjusting rod is fixedly connected within the groove. A fixing block is symmetrically fixed above the back of the cover plate, with a through hole in the center of each fixing block, and the adjusting rod is movably connected within the through hole. This patent uses multiple fixing structures to secure the perforated plate. The perforated plate can be easily disassembled and reassembled by pulling out and rotating the connecting plate; the operation is simple and convenient. The adjusting plate can be moved horizontally by rotating the adjusting knob, thereby adjusting the air intake speed, making adjustment quick and easy.

[0004] Based on research and existing technology findings, it is found that waste gas treatment processes typically require the interception and purification of solid particulate matter in the gas phase. Mesh plate filters are widely used in the pre-filter stage due to their simple structure and convenient installation. However, during operation, the surface and channels of these plate filters gradually accumulate the trapped particles, causing the equipment operating resistance to continuously increase and the filtration throughput and interception efficiency to gradually decrease. Regular shutdowns are required to disassemble, clean, or replace the filter plates, making it difficult to adapt to the requirements of long-term continuous operation. Summary of the Invention

[0010] Preferably, the release assembly further includes two cam cylinders, two rollers, and two axle brackets. The two axle brackets are respectively fixed to the first connecting plate and the second connecting plate. The axles of the two rollers are respectively fixed to the two axle brackets. The central axes of the two cam cylinders are horizontally arranged and located on both sides of the gas chamber. The release assembly also includes a rotating mechanism that enables the two cam cylinders to rotate synchronously. The outer circumferential surface of the cam cylinder is provided with a cam groove. The upper and lower ends of the cam groove are both circumferential groove segments extending along the circumferential direction of the cam cylinder. An axial straight groove segment and a helical drive segment are provided between the two circumferential groove segments. The axial straight groove segment is parallel to the axis of the cam cylinder. The helical drive segment extends helically along both the axial and circumferential directions of the cam cylinder. The joints of each groove segment are smoothly connected by an arc transition segment. The width of the cam groove is greater than the diameter of the roller. The width of the axial straight groove segment is greater than the width of the circumferential groove segment and the width of the helical drive segment. The roller is located in the cam groove.

[0011] Preferably, the rotating mechanism includes a servo geared motor, a hollow cylinder, a transmission rod, and two outer supports. The two outer supports are respectively fixed on the outer sides of the gas container. The servo geared motor is fixed to one of the outer supports. The two ends of the hollow cylinder are respectively fixed on the two sides of the gas container, and the hollow cylinder passes through the gas container. The two ends of the transmission rod are respectively rotatably mounted on the two outer supports. The output shaft of the servo geared motor is coaxially fixed with the transmission rod.

When the first or second stop bar is inserted into the mounting frame, the clamping plate on the first stop bar moves with the first stop bar, and the clamping plate on the second stop bar moves with the second stop bar until the rubber layer of the clamping plate contacts the outside of the mounting frame.

[0016] This invention provides an improved waste gas treatment device with high temperature resistance, which has the following improvements and advantages compared with the prior art: Firstly, this invention adopts a structure in which staggered baffles are spliced ​​together to form an openable filter plate. Combined with the alternating operation design of dual air paths, one in use and one in standby, and relying on the instantaneous release mechanism triggered by the cam, it realizes the dust removal effect of screen hole misalignment shearing. It can not only form a shearing effect through the relative misalignment of the baffles to directly peel off the particles embedded in the screen holes, but also overcome the limitation of conventional surface cleaning in dealing with dust accumulation inside the holes. Furthermore, it can complete the dust removal and regeneration of a single filter plate without interrupting the overall waste gas treatment process. Combined with the all-metal filter plate structure, it is suitable for high-temperature waste gas treatment scenarios.

[0017] Secondly, the impact force generated by the instantaneous release can cause the filter structure to vibrate, which can improve the particle shaking efficiency. In the dust removal state, there are no baffles inside the installation frame, which will not hinder the downward settling of particles and reduce the residue of particles inside the installation frame. The overall filter plate structure adopts a metal baffle splicing structure, combined with the isolation design of the transmission components and high-temperature gas path, which has good high temperature resistance, wear resistance and corrosion resistance, and can be adapted to the high temperature exhaust gas treatment requirements. At the same time, the filter plate adopts a modular baffle design, and a single baffle can be replaced individually if damaged, without replacing the entire filter plate. Moreover, the dust removal process does not require additional auxiliary systems such as compressed air and washing liquid, resulting in low operation and maintenance costs and adaptability to harsh exhaust gas treatment conditions with high particles and high temperatures.

[0021] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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.

[0022] This invention provides an improved waste gas treatment device with high temperature resistance. The technical solution of this invention is as follows: like Figures 1 to 12As shown, this embodiment of the invention provides a waste gas treatment device with high temperature resistance, including a diversion valve 1. Both ends of the diversion valve 1, capable of diverting flow, are fixed with gas containers 5 connected to it. A mounting frame 4 is fixed to the bottom of the gas containers 5. Multiple first baffles 2 are slidably inserted into one side of the mounting frame 4, and multiple second baffles 3 are slidably inserted into the other side of the mounting frame 4. The first baffles 2 and the second baffles 3 are staggered, with each first baffle 2 and its adjacent second baffle 3 in contact. Semicircular holes 23 are provided on both sides of each first baffle 2 and second baffle 3. Two aligned semicircular holes 23 form a sieve. Each first baffle 2... Each of the first baffles 2 and each of the second baffles 3 forms a filter plate. One end of each of the first baffles 2 is fixed with a first connecting plate 31. One end of each of the second baffles 3 is fixed with a second connecting plate 32. The first connecting plate 31 and the second connecting plate 32 are located on the outer sides of the mounting frame 4, respectively. The outside of the diversion valve 1 is provided with a release component that can instantly pull open the first connecting plate 31 and the second connecting plate 32, which can enter either end of the diversion valve 1Y head. The bottom of each of the two mounting frames 4 is fixed with an air outlet box 15. One side of the air outlet box 15 is fixed with an air intake pipe 30 connected to it. The bottom of the air outlet box 15 is fixed with a gate valve 29. As can be seen from the above connection relationship: the waste gas to be treated is introduced into either of the two gas paths at the ends of the diversion valve 1. After the waste gas enters the gas container 5, it is passed into the mounting frame 4 below. The first baffle 2 and the second baffle 3, which are staggered and closely attached to each other, together form a filter plate. The semi-circular holes 23 opened by the two baffles are combined to form a sieve hole, which filters the solid particles in the waste gas. The purified gas flows into the outlet box 15 below and is led out through the suction pipe 30. The gate valve 29 at the bottom of the outlet box 15 can control the opening and closing of the ash discharge channel. When one of the gas paths is performing the filtration operation, the other path can instantly pull open the first connecting plate 31 and the second connecting plate 32 through the release component, which drives each baffle to be pulled out of the mounting frame 4 at the same time, so that the originally aligned semi-circular holes 23 are misaligned, and the particles remaining in the sieve hole are stripped off. The two paths can work alternately to achieve continuous treatment of waste gas.

[0023] Specifically, the diversion valve 1, two air tanks 5, two mounting frames 4 and two air outlet boxes 15 are spliced ​​together to form a filter box. An elastic support structure is added to the outside of the filter box. When the first connecting plate 31 and the second connecting plate 32 are pulled apart and shake occurs, the vibration is transmitted through the elastic support structure, causing the filter box to resonate. As can be seen from the above connection relationship, when the first connecting plate 31 and the second connecting plate 32 are pulled apart instantaneously and vibrate, the vibration can be transmitted through the elastic support structure, causing the filter box to resonate and assisting the particles attached to the filter box to fall off.

[0024] Specifically, the elastic support structure includes a welded bracket 6 and multiple double-section telescopic cylinders 7. The central axis of the double-section telescopic cylinder 7 is horizontally arranged. Both ends of the double-section telescopic cylinder 7 are fixed to the filter box and the welded bracket 6, respectively. Both ends of the double-section telescopic cylinder 7 are flat. A return spring 8 is sleeved on the outside of the double-section telescopic cylinder 7. Both ends of the return spring 8 are in contact with the flat ends of the double-section telescopic cylinder 7. As can be seen from the above connection relationship, the return spring 8 sleeved on the outside of the double-section telescopic cylinder 7 can provide elastic restoring force during vibration, while buffering the impact of instantaneous tension on the overall structure and reducing structural damage.

[0025] Specifically, the release assembly includes two double-section telescopic rods 9. One end of each double-section telescopic rod 9 is rotatably mounted on the outer walls of the two sides of the air outlet box 15, and the other end of each double-section telescopic rod 9 is rotatably mounted on the first connecting plate 31 and the second connecting plate 32, respectively. Both ends of each double-section telescopic rod 9 are provided with flat-head plates 10 integrally formed with them. An ejector spring 11 is sleeved on the outer side of each double-section telescopic rod 9, and both ends of the ejector spring 11 are in contact with the two flat-head plates 10, respectively. As can be seen from the above connection relationship, the ejector spring 11 sleeved on the outside of the double-section telescopic rod 9 is in a pre-compressed state and stores elastic potential energy. When the limit constraint is released, the ejector spring 11 can release the elastic force instantly to push the double-section telescopic rod 9 to extend quickly, and drive the connecting plate and the stop bar to pull outward.

[0026] Specifically, the release assembly further includes two cam cylinders 12, two rollers 13, and two axle brackets 14. The two axle brackets 14 are respectively fixed on the first connecting plate 31 and the second connecting plate 32. The axles of the two rollers 13 are respectively fixed on the two axle brackets 14. The central axes of the two cam cylinders 12 are horizontally arranged and located on both sides of the gas chamber 5. The release assembly also includes a rotating mechanism that causes the two cam cylinders 12 to rotate synchronously. The outer circumferential surface of the cam cylinder 12 is provided with cam grooves, and the upper and lower ends of the cam grooves are both convex. The circumferential groove segment 26 extends in the circumferential direction of the wheel cylinder 12. An axial straight groove segment 24 and a helical drive segment 25 are provided between the two circumferential groove segments 26. The axial straight groove segment 24 is parallel to the axis of the cam cylinder 12. The helical drive segment 25 extends in a helical shape along both the axial and circumferential directions of the cam cylinder 12. The joints of each groove segment are smoothly connected by a circular arc transition segment. The width of the cam groove is greater than the diameter of the roller 13. The width of the axial straight groove segment 24 is greater than the width of the circumferential groove segment 26 and the width of the helical drive segment 25. The roller 13 is located in the cam groove. As can be seen from the above connection relationship: when the roller 13 is in the circumferential groove section 26, the rotation of the cam cylinder 12 will only drive the roller 13 to move relatively in the circumferential direction, and will not drive the connecting plate and the baffle to produce axial displacement, and the filter plate will maintain its current working state; when the cam cylinder 12 rotates and the roller 13 enters the axial straight groove section 24, the groove loses its axial limiting constraint on the roller 13, the pre-compressed ejector spring 11 releases its elastic force instantly, driving the roller 13 to slide quickly along the axial straight groove section 24, and then pulling the connecting plate and the baffle to be pulled out instantly; when the cam cylinder 12 continues to rotate, after the roller 13 enters the helical transmission section 25, the side wall of the helical groove will push the roller 13 to move slowly inward along the axial direction, gradually overcoming the elastic force of the ejector spring 11, pushing the connecting plate and the baffle back to the initial position, and finally the roller 13 enters the circumferential groove section 26 on the other side and remains stationary, waiting for the next extraction action.

[0027] Specifically, the rotating mechanism includes a servo geared motor 16, a hollow cylinder 17, a transmission rod 18, and two outer supports 19. The two outer supports 19 are respectively fixed on the outer sides of the gas box 5. The servo geared motor 16 is fixed to one of the outer supports 19. The two ends of the hollow cylinder 17 are respectively fixed on the two sides of the gas box 5, and the hollow cylinder 17 penetrates the gas box 5. The two ends of the transmission rod 18 are respectively rotatably mounted on the two outer supports 19. The output shaft of the servo geared motor 16 is coaxially fixed with the transmission rod 18. The two cam cylinders 12 are coaxially fixed with the transmission rod 18. The outer side of the transmission rod 18 is rotatably mounted inside the hollow cylinder 17. As can be seen from the above connection relationship, the output shaft of the servo geared motor 16 can drive the transmission rod 18 to rotate synchronously, thereby driving the two cam cylinders 12 to rotate synchronously, ensuring the consistency of the actions on both sides; the transmission rod 18 is rotatably installed inside the hollow cylinder 17, which can isolate the transmission components from the high-temperature exhaust gas in the gas box 5, and prevent the high-temperature flue gas from affecting the operational stability of the transmission components.

[0028] Specifically, grooves 22 are provided on both sides of the first baffle 2, and multiple positioning wings 20 are provided on both sides of the first baffle 2. The positioning wings 20 are offset from the semi-circular holes 23, and the positioning wings 20 are adapted to the grooves 22. The positioning wings 20 are slidably inserted into the grooves 22. Multiple slots 21 adapted to the positioning wings 20 are provided on the outer side of the mounting frame 4. As can be seen from the above connection relationship, the positioning wing 20 can maintain lateral limit during the pulling process of the baffle, prevent the baffle from deflecting, improve the connection between the first baffle 2 and the second baffle 3, and improve the overall impact resistance.

[0029] Specifically, inclined baffles are fixed on both sides of the inner frame of the mounting frame 4, and the inclined baffles are located above the first baffle 2 and the second baffle 3; As can be seen from the above connection relationship, the exhaust gas entering the installation frame 4 can be evenly guided to the entire filter plate surface. At the same time, during the dust removal process, particles are blocked and pushed into the installation frame 4, so that the detached particles can settle downwards.

[0030] Specifically, one end of each of the first baffles 2 and one end of each of the second baffles 3 are respectively fixed with a clamping plate 27; As can be seen from the above connection relationship, the clamping plate 27 connects multiple baffles in the same group into a whole, ensuring that all baffles in the same group can be pulled out synchronously, reducing the possibility of a single baffle getting stuck.

[0031] Specifically, a rubber layer 28 is laid and fixed on the side of the clamping plate 27 facing the mounting frame 4. When the first stop bar 2 or the second stop bar 3 is inserted into the mounting frame 4, the clamping plate 27 on the first stop bar 2 moves with the first stop bar 2, and the clamping plate 27 on the second stop bar 3 moves with the second stop bar 3 until the rubber layer 28 of the clamping plate 27 contacts the outside of the mounting frame 4. As can be seen from the above connection relationship, the rubber layer 28 can fill the assembly gap between the clamping plate 27 and the mounting frame 4, reduce the leakage of unfiltered exhaust gas, and at the same time buffer the rigid impact when the baffle is reset, reducing the operating noise.

[0032] It should be noted that the two suction pipes 30 are connected to the existing negative pressure system, which sends the suction gas to the purification tower or desulfurization tower for further purification. Since this is existing technology, it will not be described in detail here. The roller 13 is selected to have good impact resistance.

[0033] Working principle: The first step is the filtration stage. After the high-temperature waste gas to be treated enters the diversion valve 1, the diversion valve 1 opens one of the gas paths, and the waste gas enters the corresponding gas tank 5. After being guided by the inclined baffle, it flows to the filter plate in the mounting frame 4. At this time, the first baffle 2 and the second baffle 3 on this side are in a close fit, and the semi-circular holes 23 on both sides are aligned to form a sieve. When the waste gas passes through the filter plate, solid particles with a particle size larger than the sieve holes are trapped on the surface of the filter plate and inside the sieve holes, thus completing particle filtration. The purified gas enters the lower outlet box 15 and is transported to the subsequent treatment stage or discharged through the suction pipe 30. The gate valve 29 at the bottom of this side remains closed.

[0034] The second step is the online dust removal stage. When the operating resistance of the working side filter plate rises to the set threshold, the diversion valve 1 switches the air path, introducing the exhaust gas into another filter unit for continuous filtration. The original working side then enters the dust removal process. The servo reduction motor 16 starts, driving the transmission rod 18 and the two side cam cylinders 12 to rotate synchronously, causing the roller 13 to enter the axial straight groove section 24 from the circumferential groove section 26. The cam groove instantly releases the axial limit on the roller 13. At this time, the pre-compressed ejection spring 11 instantly releases its elastic force, pushing the double-section telescopic rod 9 to extend rapidly, pulling the first connecting plate 31 and the second connecting plate 32 to separate to both sides. All the first baffles 2 and the second baffles 3 are pulled out of the mounting frame 4 simultaneously; the originally aligned semi-circular holes 23 are quickly misaligned with the relative movement of the baffles, forming a shearing effect on the particles stuck in the screen holes, causing them to peel off from the screen holes. At the same time, the dust accumulated on the surface of the baffles falls off under the inertial action of the instantaneous pulling force; the impact force of the instantaneous pulling is synchronously transmitted to the entire filter box, and under the action of the return spring 8 of the elastic support structure, the filter box vibrates, further shaking off the particles attached to the filter box; the detached particles naturally settle to the bottom of the air outlet box 15, and the collected particles can be discharged by opening the gate valve 29 after the dust removal is completed.

[0035] The third step is the reset and standby stage. After the dust removal is completed, the cam cylinder 12 continues to rotate, and the roller 13 enters the spiral drive section 25 from the axial straight groove section 24. The spiral groove wall slowly pushes the roller 13 to move inward along the axial direction, overcoming the elastic force of the ejector spring 11 and driving the connecting plate and the baffle to gradually push inward until the first baffle 2 and the second baffle 3 re-fit, and the semi-circular hole 23 is aligned again to form a screen hole. Then the roller 13 enters the other side circumferential groove section 26 and remains stationary. This filter unit returns to the standby state, waiting for the next gas path switch. The two units cycle and alternately perform filtration and dust removal operations without stopping the machine, which can maintain the continuous operation of the exhaust gas treatment.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
