Description

Technical Field

[0001] The present invention relates to tail gas treatment technology, and specifically to a tail gas treatment device for an RTO regenerative thermal oxidizer. Background Art

[0002] As is known, an RTO regenerative thermal oxidizer is an efficient organic waste gas (VOCs) treatment device, mainly used to treat volatile organic compounds (VOCs) and other harmful gases generated in industrial processes. The RTO system uses ceramic regenerators as the medium for heat storage and exchange. Through the heat storage and heat release processes, the thermal oxidation decomposition of organic waste gas is achieved. The waste gas first enters the regenerative chamber for preheating, and then enters the combustion chamber for thermal oxidation, so that the VOCs in the organic waste gas are oxidized and decomposed into carbon dioxide and water. The oxidized high-temperature gas exchanges heat through another regenerative chamber, and after the temperature drops, it is discharged into the atmosphere. At the same time, the regenerator in the regenerative chamber absorbs heat to prepare for heating the newly input low-temperature waste gas in the next cycle.

[0003] The deficiencies of the prior art are as follows. After using the RTO regenerative thermal oxidizer to treat the tail gas, the tail gas to be treated is discharged into the combustion chamber through a blower via an inlet pipe. A cleaning chamber, a heating chamber, and a cooling chamber are also arranged in the combustion chamber to treat the waste gas, and the treated waste gas is discharged through a pipe into the exhaust pipe and discharged outwards. However, the amount of tail gas discharged from the tail gas treatment by the incinerator will change due to problems such as the progress and time of industrial production. The exhaust pipes are all set at a fixed height, and dust adsorption and atomizing nozzles are installed in the exhaust pipe to cool the tail gas while collecting the dust particles in the tail gas. Industrial production also has changes between peak and trough periods. Therefore, this will also lead to changes in the amount of tail gas discharged. Using the exhaust pipe with a fixed height to discharge the tail gas all the time, the atomizing nozzles arranged in the exhaust pipe will continuously spray out water for cooling and dust removal. During the trough period of industrial production, the amount of discharged tail gas is small, and not much water for cooling and dust removal is needed. However, all the atomizing nozzles in the exhaust pipe are continuously opened, which will cause waste of resources. And by manually controlling the water spraying amount of the atomizing nozzles, the workload of the staff will be increased, and the drainage amount of the atomizing nozzles cannot be automatically adjusted, affecting the effect of tail gas treatment. Summary of the Invention

[0004] The purpose of the present invention is to provide a tail gas treatment device for an RTO regenerative thermal oxidizer to solve the above deficiencies in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: including: a combustion chamber, one end of the combustion chamber is connected to an inlet pipe through a blower, the other end of the combustion chamber is connected to an exhaust pipe, and further includes:

[0006] A plurality of baffles, wherein the plurality of baffles are rotatably installed in the smoke exhaust pipe at intervals, and the outer diameter of the baffles is smaller than the inner diameter of the smoke exhaust pipe;

[0007] Smoke pipe switching mechanism: It is transmission-connected with the baffle, and according to the amount of exhaust gas generated by the peak of industrial production, the impact force of the exhaust gas on the baffle when it is discharged upward along the smoke exhaust pipe is utilized. When the baffle is impacted and flipped upward from the lateral position, the baffle drives the smoke pipe switching mechanism to seal the smoke guide pipe arranged at the air inlet end of the smoke outlet pipe at the corresponding position, while the exhaust gas continues to be discharged upward along the smoke exhaust pipe. When the baffle is subjected to a smaller impact force of the exhaust gas and maintains a lateral position, the smoke guide mechanism arranged at the bottom of the baffle discharges the treated exhaust gas from the smoke outlet pipe at the corresponding position.

[0008] As a further description of the above technical solution: the smoke outlet pipes are evenly spaced and installed on one side of the smoke exhaust pipe and are connected to the smoke exhaust pipe, and the number of the baffles matches the number of the smoke outlet pipes.

[0009] As a further description of the above technical solution: the baffle is rotatably connected to the inner wall of the smoke exhaust pipe at one end away from the smoke exhaust pipe through a torsion spring shaft, the baffle is arranged above the air inlet end of the smoke exhaust pipe, and a rubber sleeve with deformation ability is connected to the top of the baffle, and the rubber sleeve is fitted against the inner wall of the smoke exhaust pipe.

[0010] As a further description of the above technical solution: the smoke pipe switching mechanism comprises: a smoke guide pipe fixedly installed at the air inlet end of the smoke outlet pipe inserted in the smoke exhaust pipe, one end of the smoke guide pipe is connected to the smoke outlet pipe, and the other end faces the smoke exhaust pipe and is installed with a fixed plate, a movable groove is provided on the inner side wall of the middle part of the smoke guide pipe, a movable plate is movably installed in the movable groove, and a matching smoke exhaust hole is provided between the movable plate and the fixed plate, when the fixed plate and the movable plate are in the same horizontal position, the movable plate and the smoke exhaust holes opened in the fixed plate are connected to each other, when the movable plate and the fixed plate are misaligned with each other, the smoke exhaust holes are misaligned and blocked with each other, a resistance rod is fixedly installed on the top of the movable plate, the resistance rod slides through the through hole opened at the top of the movable groove, the outer side of the resistance rod is connected to the inner side wall of the movable groove by a reset spring, the top of the resistance rod passes through the through hole and is inserted into the outer side of the smoke guide pipe and resists the inner side wall of the connecting clamp, and the top of the clamp is rotatably connected to the bottom of the baffle near one end of the smoke outlet pipe through an automatically rotatable rotating frame and a rotating rod.

[0011] As a further description of the above technical solution: A smoke guiding mechanism is provided at the bottom of multiple said baffles. The smoke guiding mechanism is configured such that when the amount of exhaust gas discharged is small or the impact force on the baffle is small, it cannot impact and open the baffle, guiding the exhaust gas to one side and discharging it outward through the smoke outlet pipe in the open state at the corresponding position. When the amount of exhaust gas discharged is large and the impact force on the baffle is large, it impacts and opens the baffle, and can utilize the impact speed of the exhaust gas itself to increase the impact force on the baffle, thereby reopening and flipping the baffle upward to continue discharging the exhaust gas upward along the smoke exhaust pipe for cooling and dust removal.

[0012] As a further description of the above technical solution: The smoke guiding mechanism includes rotation holes evenly spaced and opened at the bottom of the baffle, and a fish scale deflector is rotatably connected in the rotation holes through a rotating shaft.

[0013] As a further description of the above technical solution: The baffle is a cylinder with a right trapezoidal cross-section, with the hypotenuse facing down as the impact surface for receiving the exhaust gas, and the high point of the hypotenuse is set above the smoke guiding pipe, and the low point of the hypotenuse is set on the other side inside the smoke exhaust pipe, guiding the exhaust gas through the diversion of the hypotenuse into the smoke guiding pipe.

[0014] As a further description of the above technical solution: The fit between the rubber sleeve provided at the top outside of the baffle and the inner wall of the smoke exhaust pipe is small, and the deformation force of the rubber sleeve is strong. When the baffle flips inside the smoke exhaust pipe, it adapts to the flipping of the baffle through the self-deformation of the rubber sleeve.

[0015] As a further description of the above technical solution: When the baffle is in the horizontal closed position, under the action of gravity, the tip part of the fish scale deflector drops downward, and when impacted by exhaust gas with different speeds and volumes, it will flip to different degrees to achieve the functions of guiding the flow or increasing the impact force on the baffle.

[0016] In the above technical solution, for an RTO regenerative incinerator tail gas treatment device provided by the present invention, the snap ring is provided in a hollow semi-circular arc shape adapted to the outer diameter shape and size of the smoke guiding pipe, and is connected to the bottom of the baffle through a rotatable rotating rod and a rotating frame. With the flipping of the baffle during opening and closing, the open end of the snap ring fits and flips along the inner wall of the smoke exhaust pipe and is detachably sleeved on the outer top of the smoke guiding pipe. When the baffle is opened, the exhaust gas can smoothly pass through the hollow snap ring without hindering the discharge of the exhaust gas.

[0017] An RTO regenerative incinerator tail gas treatment device provided by the present invention has the following beneficial effects:

[0018] 1. Automatically adjust the exhaust gas emission path: According to the change in the volume of industrial production exhaust gas, utilize the impact force of the exhaust gas itself to achieve automatic adjustment of the emission path. During the low-production period, the exhaust gas volume is small and the impact force is weak. The exhaust gas is discharged from the smoke outlet pipe through the smoke guiding mechanism at the bottom of the baffle. During the peak-production period, the exhaust gas volume is large and the impact force is strong. The baffle flips to block the corresponding smoke guiding pipe, and the exhaust gas is discharged upward until it encounters a baffle that cannot be forced open and then is discharged from the corresponding smoke outlet pipe, while improving the effect of air pollution control.

[0019] 2. Optimize the diversion and impact effects: The baffle is in the shape of a right-angled trapezoid, and the inclined side diversion design is combined with the fish-scale diversion plate. When the exhaust gas volume is small, it diverts the exhaust gas; when the exhaust gas volume is large, it blocks the flow to amplify the impact force, ensuring that the equipment can efficiently handle different exhaust gas volume situations.

[0020] 3. Save resources: Cooperate with the atomizing nozzles below different smoke outlet pipes, and the atomizing nozzles are electrically connected to the baffle. When the exhaust gas volume is small, the atomizing nozzles are closed or slightly opened; when the exhaust gas volume is large, the corresponding atomizing nozzles are opened, avoiding the waste of water resources caused by the continuous opening of the atomizing nozzles during the low-production period of industrial production.

[0021] 4. Reduce the workload of personnel: There is no need for manual control of the water spraying volume of the atomizing nozzles. The equipment can automatically adjust according to the exhaust gas volume, reducing the workload of the staff. Description of the Drawings

When the baffle 7 is impacted and flipped upward from the lateral position, the baffle 7 drives the smoke pipe switching mechanism to seal the smoke guide pipe 6 arranged at the air inlet end of the smoke outlet pipe 5 at the corresponding position, and the exhaust gas continues to be discharged upward along the smoke exhaust pipe 4. When the baffle 7 is subjected to a smaller impact force of the exhaust gas and maintains a lateral position, the smoke guide mechanism arranged at the bottom of the baffle 7 discharges the treated exhaust gas from the smoke outlet pipe 5 at the corresponding position.

When the movable plate 11 and the fixed plate 14 are misaligned with each other, the smoke exhaust holes are misaligned and blocked. A resistance rod 9 is fixedly installed on the top of the movable plate 11. The resistance rod 9 slides through the through hole 13 opened at the top of the movable groove 12. The outer side of the resistance rod 9 is connected to the inner wall of the movable groove 12 through the reset spring 10. The top of the resistance rod 9 passes through the through hole 13 and is inserted into the outer side of the smoke guide pipe 6 and resists the inner wall of the connecting clamp 8. The top of the clamp 8 is rotatably connected to the bottom of the baffle 7 near the end of the smoke outlet pipe 5 through an automatically rotatable rotating frame 19 and a rotating rod 20.

[0039] In another embodiment provided by the present invention, the rubber sleeve 21 arranged on the top of the outer side of the baffle 7 has a small fit with the inner wall of the smoke exhaust pipe 4, and the rubber sleeve 21 has a strong deformation force. When the baffle 7 is flipped in the smoke exhaust pipe 4, the rubber sleeve 21 adapts to the flipping of the baffle 7 through its own deformation.

[0040] In another embodiment provided by the present invention, the clamping ring 8 is arranged in a hollow semicircular arc shape that is compatible with the outer diameter shape and size of the smoke guide pipe 6, and is connected to the bottom of the baffle 7 through an automatically rotatable rotating rod 20 and a rotating frame 19. As the baffle 7 is flipped during opening and closing, the open end of the clamping ring 8 fits the inner wall of the smoke exhaust pipe 4 and flips and is detachably sleeved on the outer top of the smoke guide pipe 6. When the baffle 7 is opened, the exhaust gas can pass smoothly through the hollow clamping ring 8 without hindering the discharge of the exhaust gas.

[0041] In another embodiment provided by the present invention, a smoke guiding mechanism is arranged at the bottom of the plurality of baffles 7. The smoke guiding mechanism is arranged so that when the amount of exhaust gas discharged is small or the impact force on the baffle 7 is small, the baffle 7 cannot be impacted open, and the exhaust gas is guided to one side and discharged outwardly through the smoke outlet pipe 5 in the open state at the corresponding position. When the amount of exhaust gas discharged is large and the impact force on the baffle 7 is large, the baffle 7 is impacted open, and the impact speed of the exhaust gas itself can be used to increase the impact force on the baffle 7, so that the baffle 7 is reopened and flipped upward to open, and the exhaust gas continues to be discharged upward along the smoke exhaust pipe 4 for cooling and dust removal.

[0042] In another embodiment provided by the present invention, preferably, the smoke guiding mechanism includes rotating holes 16 evenly spaced at the bottom of the baffle 7 , and the fish-scale guide plate 15 is rotatably connected in the rotating hole 16 via a rotating shaft 17 .

[0044] Overall structure:

[0045] An RTO regenerative thermal oxidizer exhaust gas treatment device: includes a combustion chamber 3, one end of the combustion chamber 3 is connected to an intake pipe 1 through a blower 2, and the other end is connected to an exhaust pipe 4.

[0046] Multiple baffles 7: are rotatably installed in the exhaust pipe 4 at intervals, and the outer diameter of the baffle 7 is smaller than the inner diameter of the exhaust pipe 4. One end of the baffle 7 away from the smoke outlet pipe 5 is rotatably connected to the inner side wall of the exhaust pipe 4 through a torsion spring shaft 18, and the baffle 7 is arranged above the intake end of the smoke outlet pipe 5. The baffle 7 is a cylinder with a right trapezoidal cross-section, and the hypotenuse faces downward as the impact surface for receiving exhaust gas. The high point of the hypotenuse is set above the smoke guiding pipe 6, and the low point is set on the other side inside the exhaust pipe 4, for guiding the exhaust gas through the hypotenuse to the smoke guiding pipe 6. A rubber sleeve 21 with deformation ability is connected to the outside of the top of the baffle 7, and the rubber sleeve 21 fits with the inner side wall of the exhaust pipe 4. The fit degree between the rubber sleeve 21 and the inner side wall of the exhaust pipe 4 is small and the deformation force is strong. When the baffle 7 flips in the exhaust pipe 4, the rubber sleeve 21 can adapt to the flip of the baffle 7 through its own deformation.

[0047] Smoke pipe switching mechanism: is in transmission connection with the baffle 7. According to the different exhaust gas volumes caused by the peak of industrial production, it works by using the impact force of the exhaust gas flowing upward in the exhaust pipe 4 on the baffle 7. When the baffle 7 is impacted from the horizontal position and flips upward, the baffle 7 drives the smoke pipe switching mechanism to block the smoke guiding pipe 6 at the intake end of the corresponding smoke outlet pipe 5, so that the exhaust gas continues to flow upward along the exhaust pipe 4; when the impact force on the baffle 7 is small and it remains in the horizontal position, the smoke guiding mechanism arranged at the bottom of the baffle 7 discharges the treated exhaust gas from the corresponding smoke outlet pipe 5 to the outside.

[0048] Arrangement of the smoke outlet pipe 5:

[0049] The smoke outlet pipes 5 are evenly spaced and installed on one side of the exhaust pipe 4 and communicate with the inside of the exhaust pipe 4, and the number of the baffles 7 is adapted to the number of the smoke outlet pipes 5.

[0050] Specific structure of the smoke pipe switching mechanism:

[0051] The smoke pipe switching mechanism includes a smoke guide pipe 6 fixedly installed at the air inlet end of the smoke outlet pipe 5 inserted in the smoke exhaust pipe 4, one end of the smoke guide pipe 6 is connected to the smoke outlet pipe 5, and the other end faces the smoke exhaust pipe 4 and is installed with a fixed plate 14. A movable groove 12 is provided on the inner side wall of the middle part of the smoke guide pipe 6, and a movable plate 11 is movably installed in the movable groove 12, and a matching smoke exhaust hole is provided between the movable plate 11 and the fixed plate 14. When the fixed plate 14 and the movable plate 11 are at the same horizontal position, the smoke exhaust holes opened in the movable plate 11 and the fixed plate 14 are connected to each other; when the movable plate 11 and the fixed plate 14 are misaligned with each other, the smoke exhaust holes are misaligned and blocked with each other. A resisting rod 9 is fixedly installed on the top of the movable plate 11. The resisting rod 9 slides through the through hole 13 opened at the top of the movable groove 12. The outer side of the resisting rod 9 is connected to the inner side wall of the movable groove 12 through the reset spring 10. The top of the resisting rod 9 passes through the through hole 13 and is inserted into the outer side of the smoke guide pipe 6 and resists the inner side wall of the connecting clamp ring 8. The top of the clamp ring 8 is rotatably connected to the bottom of the baffle 7 near the end of the smoke outlet pipe 5 through the automatically rotatable rotating frame 19 and the rotating rod 20. The clamp ring 8 is set in a hollow semicircular arc shape that matches the outer diameter shape and size of the smoke guide pipe 6. With the flipping of the baffle 7 when opening and closing, the open end of the clamp ring 8 is flipped against the inner side wall of the smoke exhaust pipe 4 and can be detachably sleeved on the outer top of the smoke guide pipe 6. When the baffle 7 is opened, the exhaust gas can pass smoothly through the hollow clamp ring 8 without hindering the exhaust gas discharge.

[0052] Smoke guide mechanism settings:

[0053] A smoke guide mechanism is arranged at the bottom of the plurality of baffles 7. The smoke guide mechanism is arranged such that when the amount of exhaust gas discharged is small or the impact force on the baffle 7 is small, the baffle 7 cannot be impacted to open, and the exhaust gas is guided to one side and discharged outward through the smoke outlet pipe 5 in the corresponding open state; when the amount of exhaust gas discharged is large and the impact force on the baffle 7 is large, the baffle 7 is impacted to open, and the impact force on the baffle 7 can be increased by using the impact speed of the exhaust gas itself, so that the baffle 7 is flipped upward and opened, so that the exhaust gas continues to be discharged upward along the smoke exhaust pipe 4 for cooling and dust removal. The smoke guide mechanism includes rotating holes 16 evenly spaced at the bottom of the baffle 7, and the fish scale guide plate 15 is rotatably connected in the rotating hole 16 through a rotating shaft 17. When the fish scale guide plate 15 is closed in the horizontal position, under the action of gravity, the tip of the fish scale guide plate 15 falls downward, and when impacted by exhaust gas of different speeds and volumes, it will flip to different degrees, realizing the function of guiding or increasing the impact force on the baffle 7.

[0054] Working principle:

[0055] Low period of industrial production: During the low period of industrial production, less tail gas is emitted from industrial production. When the tail gas is discharged through the exhaust pipe 4, the upward impact force is small. When the tail gas contacts the baffle 7, it will be guided into the smoke outlet pipe 5 communicated with the exhaust pipe 4 along the fish scale guide plate 15 arranged on the inclined surface at the bottom of the baffle 7. At this time, since the baffle 7 is in a horizontal state, the extrusion of the contact rod 9 by the snap ring 8 makes the smoke exhaust holes opened between the movable plates 11 installed in the smoke guide pipe 6 communicate with the smoke exhaust holes opened in the fixed plate 14. The treated tail gas is guided into the smoke guide pipe 6 through the baffle 7 for discharge.

[0056] High period of industrial production: During the high period of industrial production, more tail gas is discharged. When the tail gas is discharged upward through the exhaust pipe 4, it will impact the fish scale guide plate 15 at the bottom of the baffle 7 above the exhaust pipe 4 from the bottom. Due to more tail gas, the upward impact force is large, and it cannot be discharged from the lower smoke guide pipe 6. Moreover, the tail gas that has not been fully cooled will also impact upward due to its own heat, and the baffle 7 will be turned upward and opened under the action of the torsion spring shaft 18 connecting the inner side wall of the exhaust pipe 4 on one side. When the baffle 7 is turned upward and opened, the snap ring 8 rotatably installed on the other side below through the rotating frame 19 and the rotating rod 20 is separated from the upper part of the lower smoke guide pipe 6. At this time, the contact rod 9 is subjected to the elastic return force of the return spring 10, so that the movable plate 11 slides upward in the movable groove 12, misaligning the smoke exhaust holes between the movable plate 11 and the fixed plate 14. The treated tail gas cannot be discharged from the smoke outlet pipe 5 and can only continue to be discharged upward through the exhaust pipe 4 until it reaches the baffle 7 that cannot be impacted open, and then is discharged outward along the smoke outlet pipe 5 opened at the corresponding position of the baffle 7. It should be noted that the baffle 7 is connected to the inner side wall of the exhaust pipe 4 through the torsion spring shaft 18, and the torsion spring shaft 18 itself has a turning force and will automatically turn downward and reset after losing the impact force of the tail gas. At the same time, there is also a torsion spring turning effect between the rotating frame 19 provided at the bottom of the other end of the baffle 7 and the rotating rod 20 provided at the top of the snap ring 8, so as to ensure that during the process of the baffle 7 driving the clamping plate to turn upward, the snap ring 8 can rotate after contacting the inner side wall of the exhaust pipe 4 without affecting the turning of the baffle 7, and when the baffle 7 turns downward and resets, the snap ring 8 can also automatically reset and correspondingly sleeve on the upper part of the smoke guide pipe 6 for contact.

[0057] According to the peak changes in industrial production, by using the amount of tail gas emissions, the smoke exhaust pipe 5 for discharging the tail gas is adjusted by the upward impact force of the tail gas itself. Corresponding atomizing nozzles are arranged below different smoke exhaust pipes 5, and the atomizing nozzles are electrically connected to the baffle 7 arranged below. After the baffle 7 below is opened, the tail gas will be discharged upward to the atomizing nozzle. At this time, the atomizing nozzle is correspondingly opened to spray and cool and remove dust from the tail gas, which has better practicability. When the amount of tail gas is small, the tail gas has a certain impact force on the fish scale deflector 15, causing the fish scale deflector 15 to turn towards the side close to the baffle 7, providing a guiding effect on the tail gas, and guiding the tail gas into the smoke guide pipe 6 and the smoke exhaust pipe 5 arranged on one side below the corresponding baffle 7 and discharging it outwards; when the amount of tail gas is large, the upward impact force of the tail gas is large and rapid, and the tail gas will quickly fill the position on the side of the fish scale deflector 15 close to the baffle 7, impacting the baffle 7 upward. At this time, the fish scale deflector 15 will only turn upward slightly or not at all, but instead provide a certain flow resistance effect on the tail gas, amplifying the impact force of the tail gas on the baffle 7, thereby impacting and opening the baffle 7 upward.

[0058] After using the RTO regenerative thermal oxidizer to treat the tail gas, the tail gas to be treated is discharged into the combustion chamber 3 through the air inlet pipe 1 by the blower 2. A cleaning chamber, a heating chamber and a cooling chamber are also arranged in the combustion chamber 3 to treat the waste gas, and the treated waste gas is discharged outwards through the pipeline into the smoke exhaust pipe 4. However, the amount of tail gas discharged by the incinerator after treating the tail gas will change with the progress and time of industrial production and other issues. The smoke exhaust pipe 4 is set at a fixed height, and while installing dust adsorption and atomizing nozzles in the smoke exhaust pipe 4 to cool and cool the tail gas, the dust particles in the tail gas can be collected. There are also changes in the peak and trough periods of industrial production. Therefore, this will also lead to changes in the amount of tail gas emissions. Using the smoke exhaust pipe 4 with a fixed height to discharge the tail gas all the time, the atomizing nozzles arranged in the smoke exhaust pipe 4 will continuously spray cooling and dust removal water outwards. During the low period of industrial production, the discharged tail gas is less, and there is no need for too much cooling and dust removal water. However, all the atomizing nozzles in the smoke exhaust pipe 4 are continuously opened, which will cause waste of resources. And by manually controlling the water spraying amount of the atomizing nozzles, the workload of the staff will be increased, and the drainage amount of the atomizing nozzles cannot be automatically adjusted;

[0059] According to the changes between the peak and trough periods of industrial production, during the trough period of industrial production, the exhaust gas emitted by industrial production is less, and when the exhaust gas is discharged through the smoke exhaust pipe 4, the upward impact force is smaller. When the exhaust gas contacts the baffle 7, it will be guided to the smoke outlet pipe 5 connected to one side of the smoke exhaust pipe 4 along with the fish scale guide plate 15 set on the inclined surface of the bottom of the baffle 7. At this time, since the baffle 7 is horizontal, the smoke exhaust holes opened between the movable plates 11 installed in the smoke guide pipe 6 are connected to the smoke exhaust holes opened in the fixed plate 14 through the compression of the retaining ring 8 on the resistance rod 9. At this time, the treated exhaust gas is guided to the smoke guide pipe 6 through the baffle 7 for discharge;

[0060] During the peak period of industrial production, the exhaust gas is more, and when the exhaust gas is more, it will impact the fish scale guide plate 15 at the bottom of the baffle 7 from the bottom to the top of the exhaust pipe 4. Since the exhaust gas is more, the upward impact force is also greater, and it cannot be discharged from the smoke guide pipe 6 below. In addition, the exhaust gas that has not been completely cooled will also impact upward due to its own heat, and the baffle 7 will be flipped upward under the action of the torsion spring shaft 18 connected to the inner side wall of the exhaust pipe 4 on one side. When the baffle 7 is flipped upward and opened, the other side The clamp ring 8 installed by rotating the rotating frame 19 and the rotating rod 20 at the lower side is separated from the upper part of the lower smoke guide pipe 6. At this time, the resistance rod 9 is subjected to the rebound effect of the reset spring 10 to slide the movable plate 11 upward in the movable groove 12, and the movable plate 11 is misaligned with the smoke exhaust hole opened in the fixed plate 14. The treated exhaust gas cannot be discharged from the smoke exhaust pipe 5 and can only continue to be discharged to the upper part of the smoke exhaust pipe 4 until it reaches the baffle plate 7 that cannot be impacted and opened, and then it can be discharged outward along the smoke exhaust pipe 5 opened at the corresponding position of the baffle plate 7.

[0061] It should be noted that the baffle 7 is connected to the inner wall of the smoke exhaust pipe 4 through a torsion spring shaft 18. The torsion spring shaft 18 has a rotation force. After losing the impact force of the exhaust gas, it will automatically flip down and reset. At the same time, there is a torsion spring rotation effect between the rotating frame 19 set at the bottom of the other end of the baffle 7 and the rotating rod 20 set at the top of the clamping ring 8, so as to ensure that the clamping ring 8 can rotate after contacting the inner wall of the smoke exhaust pipe 4 during the process of the baffle 7 driving the clamping plate to flip upward, and will not affect the flipping of the baffle 7. At the same time, when the baffle 7 flips down and resets, the clamping ring 8 can also automatically reset itself and can be correspondingly sleeved on the top of the smoke guide pipe 6 to resist;

[0062] According to the change of the peak value of industrial production, the amount of exhaust gas emission is adjusted by utilizing the upward impact force of the exhaust gas itself, and corresponding atomizing nozzles are arranged under different smoke outlet pipes 5, and the atomizing nozzles are electrically connected to the baffle 7 arranged below. After the baffle 7 below is opened, the exhaust gas will be discharged to the atomizing nozzle above. At this time, the atomizing nozzle is opened accordingly to spray the exhaust gas for cooling and dust removal, which is more practical.

[0063] The baffle 7 is set as a disc with a right trapezoidal cross-section, and the inclined surface faces downward. Scaled flow guiding plates 15 are arranged on the inclined surface in the same direction as the inclined surface flow guiding direction, and the scaled flow guiding plates 15 are installed in the rotating holes 16 through rotating shafts 17. When the baffle 7 is in the normally closed state, due to the action of gravity, the scaled flow guiding plates 15 are in a state of popping outwards;

[0064] When the amount of tail gas is small, there will also be a certain impact force of the tail gas on the scaled flow guiding plates 15, and the scaled flow guiding plates 15 are flipped towards the side close to the baffle 7 to provide a flow guiding effect for the tail gas, and the tail gas is guided into the smoke guiding pipe 6 and the smoke outlet pipe 5 arranged on one side below the corresponding baffle 7 and discharged outwards;

[0065] When the amount of tail gas is large, the upward impact force of the tail gas is large and relatively fast. Therefore, the tail gas will quickly fill the position close to the baffle 7 on one side of the scaled flow guiding plates 15 and impact the baffle 7 upwards. The scaled flow guiding plates 15 will only flip upwards with a small amplitude or even not flip at all. Instead, it will provide a certain flow blocking effect on the tail gas, thereby amplifying the impact force of the tail gas on the baffle 7 and thus impacting the baffle 7 upwards to open it.

[0066] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
