Description

Technical Field

[0001] The invention relates to tail gas treatment technology, in particular to a RTO heat storage type incinerator tail gas treatment device. Background Art

[0002] As is known, the RTO thermal storage incinerator is a highly efficient organic waste gas (VOCs) treatment equipment, mainly used to treat volatile organic compounds (VOCs) and other harmful gases generated in industrial processes. The RTO system uses ceramic thermal storage as a medium for heat storage and exchange, and realizes thermal oxidation decomposition of organic waste gas through heat storage and heat release processes. The waste gas first enters the thermal storage chamber for preheating, and then enters the combustion chamber for thermal oxidation, so that the VOC in the organic waste gas is oxidized and decomposed into carbon dioxide and water. The oxidized high-temperature gas passes through another thermal storage chamber for heat exchange, and is discharged into the atmosphere after the temperature is reduced. At the same time, the thermal storage body of the thermal storage chamber absorbs heat to prepare for the next cycle to heat the newly input low-temperature waste gas.

[0003] The disadvantage of the prior art is that after the exhaust gas is treated by the RTO regenerative incinerator, the exhaust gas to be treated is discharged into the combustion chamber through the air intake pipe through the blower. The combustion chamber is also provided with a cleaning chamber, a heating chamber and a cooling chamber to treat the exhaust gas, and the treated exhaust gas is discharged into the exhaust pipe through a pipeline and discharged outward. However, the amount of exhaust gas discharged by the incinerator for exhaust gas treatment will change with the progress and time of industrial production, and the exhaust pipe is set at a fixed height, and dust adsorption and atomizing nozzles are installed in the exhaust pipe to cool the exhaust gas while being able to Dust particles are collected, and industrial production will also have peak and trough periods, which will lead to changes in the amount of exhaust emissions. The exhaust pipe at a fixed height has been used to discharge the exhaust gas. The atomizing nozzles installed in the exhaust pipe will continuously spray out cooling and dust removal water. During the trough period of industrial production, the exhaust gas discharged is less, and too much cooling and dust removal water is not required. However, all the atomizing nozzles in the exhaust pipe are continuously opened, which will cause a waste of resources. Manually controlling the water spraying amount of the atomizing nozzles will increase the workload of the staff, and the water discharge amount of the atomizing nozzles cannot be automatically adjusted, affecting the effect of exhaust gas treatment. Summary of the invention

[0009] As a further description of the above technical solution: a smoke guiding mechanism is arranged at the bottom of the plurality of baffles, and the smoke guiding mechanism is arranged so that when the amount of exhaust gas discharged is small or the impact force on the baffle is small, the baffle cannot be impacted open, and the exhaust gas is guided to one side and discharged outwardly 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, the baffle is impacted open, and the impact speed of the exhaust gas itself can be used to increase the impact force on the baffle, so that the baffle is reopened and flipped upward to open, and the exhaust gas continues to be discharged upward along the smoke exhaust pipe for cooling and dust removal.

[0010] As a further description of the above technical solution: the smoke guiding mechanism includes rotating holes evenly spaced at the bottom of the baffle, and the fish-scale guide plate is rotatably connected in the rotating holes via a rotating shaft.

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.

[0027] 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.

[0028] 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.

[0029] 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 .

[0030] In another embodiment provided by the present invention, when the baffle 7 is in a horizontal position and closed, the tip of the fish scale guide plate 15 falls downward under the action of gravity, and when impacted by exhaust gases of different speeds and volumes, it flips to different degrees to achieve the function of guiding or increasing the impact force on the baffle 7.

[0031] Overall structure: An RTO thermal storage incinerator tail gas treatment device comprises a combustion chamber 3, one end of the combustion chamber 3 is connected to an air intake pipe 1 through a blower 2, and the other end is connected to a smoke exhaust pipe 4.

[0032] Multiple baffles 7: Installed in the exhaust pipe 4 in an interval manner, the outer diameter of the baffle 7 is smaller than the inner diameter of the exhaust pipe 4. The end of the baffle 7 away from the exhaust pipe 5 is rotatably connected to the inner wall of the exhaust pipe 4 through the torsion spring shaft 18, and the baffle 7 is arranged above the air inlet end of the exhaust pipe 5. The baffle 7 is a cylinder with a right-angle trapezoidal cross section, with the hypotenuse facing downward as the impact surface for receiving the exhaust gas, the high point of the hypotenuse is arranged above the smoke guide pipe 6, and the low point is arranged on the other side of the exhaust pipe 4, which is used to guide the exhaust gas into the smoke guide pipe 6 through the hypotenuse. A rubber sleeve 21 with deformation ability is connected to the top of the baffle 7, and the rubber sleeve 21 fits with the inner wall of the exhaust pipe 4. The rubber sleeve 21 has a small fit with the inner wall of the exhaust pipe 4 and a strong deformation force. When the baffle 7 is turned over in the exhaust pipe 4, the rubber sleeve 21 can adapt to the turning of the baffle 7 through its own deformation.

[0033] Smoke pipe switching mechanism: It is connected to the baffle 7 by transmission. According to the different exhaust gas volumes caused by the peak of industrial production, the impact force of the exhaust gas on the baffle 7 when it is discharged upward along the smoke exhaust pipe 4 is used to work. When the baffle 7 is impacted and flipped upward from the lateral position, the baffle 7 drives the smoke pipe switching mechanism to block the smoke guide pipe 6 set at the air inlet end of the smoke outlet pipe 5 at the corresponding position, so that the exhaust gas continues to be discharged upward along the smoke exhaust pipe 4; when the baffle 7 is subjected to a small impact force of the exhaust gas and maintains a lateral position, the smoke guide mechanism set at the bottom of the baffle 7 discharges the treated exhaust gas from the smoke outlet pipe 5 at the corresponding position.

[0034] Smoke outlet pipe 5 settings: The smoke outlet pipes 5 are evenly spaced and installed on one side of the smoke exhaust pipe 4 and are connected to the smoke exhaust pipe 4 , and the number of the baffles 7 matches that of the smoke outlet pipes 5 .

[0035] Specific structure of smoke tube switching mechanism: 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.

[0036] Smoke guide mechanism settings: 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.

[0037] Working principle: Low period of industrial production: During the low period of industrial production, the exhaust gas emitted by industrial production is less, and the upward impact force of the exhaust gas when it is discharged through the exhaust pipe 4 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 exhaust pipe 4 along the fish scale guide plate 15 set on the inclined surface at the bottom of the baffle 7. At this time, since the baffle 7 is horizontal, the clamping ring 8 squeezes the resistance rod 9, so that the exhaust holes opened between the movable plates 11 installed in the smoke guide pipe 6 are connected with the exhaust holes opened in the fixed plate 14, and the treated exhaust gas is guided to the smoke guide pipe 6 through the baffle 7 for discharge.

[0038] Peak period of industrial production: During the peak period of industrial production, more exhaust gas is discharged. When the exhaust 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 from the bottom to the top of the exhaust pipe 4. Due to the large amount of exhaust gas, the upward impact force is large, and it cannot be discharged from the smoke guide pipe 6 below, and the exhaust gas that has not been completely cooled will also impact upward due to its own heat, flipping the baffle 7 upward under the action of the torsion spring shaft 18 connected to the inner wall of the exhaust pipe 4 on one side. When the baffle 7 is flipped upward and opened, the clamping ring 8 on the other side, which is rotatably installed through the rotating frame 19 and the rotating rod 20, is separated from the top of the smoke guide pipe 6 below. At this time, the resistance rod 9 is rebounded by the reset spring 10, so that the movable plate 11 slides 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 top of the smoke exhaust pipe 4 until it cannot be impacted to the baffle plate 7, and then it is discharged outward along the smoke exhaust pipe 5 opened at the corresponding position of the baffle plate 7. It should be noted that the baffle plate 7 is connected to the inner wall of the smoke exhaust pipe 4 through the torsion spring shaft 18, and the torsion spring shaft 18 itself has a rotation force, and it will automatically flip down and reset after losing the impact force of the exhaust gas. At the same time, there is also a torsion spring rotation effect between the rotating frame 19 arranged at the bottom of the other end of the baffle 7 and the rotating rod 20 arranged 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, without affecting the flipping of the baffle 7, and when the baffle 7 flips downward and resets, the clamping ring 8 can also automatically reset and resist the corresponding sleeve above the smoke guide pipe 6.

[0039] According to the peak change of industrial production, the amount of exhaust gas emission is used to adjust the exhaust gas exhaust pipe 5 through the upward impact force of the exhaust gas itself. Corresponding atomizing nozzles are set below different smoke exhaust pipes 5, and the atomizing nozzles are electrically connected to the baffle 7 set 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 correspondingly opened to spray the exhaust gas for cooling and dust removal, which is more practical. When the amount of exhaust gas is small, the exhaust gas has a certain impact force on the fish scale guide plate 15, causing the fish scale guide plate 15 to flip toward the side of the baffle plate 7, providing a guiding effect for the exhaust gas, and guiding the exhaust gas to the smoke guide pipe 6 and the smoke outlet pipe 5 arranged on the side below the corresponding baffle plate 7 for discharge outward; when the amount of exhaust gas is large, the force of the exhaust gas impacting upward is large and fast, and the exhaust gas will quickly fill the position of the fish scale guide plate 15 close to the baffle plate 7, impacting the baffle 7 upward. At this time, the fish scale guide plate 15 will only flip upward to a small extent or even not flip, but provide a certain flow resistance effect for the exhaust gas, amplify the impact force of the exhaust gas on the baffle plate 7, thereby impacting the baffle 7 upward to open it. After the exhaust gas is treated by the RTO regenerative incinerator, the exhaust gas to be treated is discharged into the combustion chamber 3 through the air intake pipe 1 through the blower 2. The combustion chamber 3 is also provided with a cleaning chamber, a heating chamber and a cooling chamber to treat the exhaust gas, and the treated exhaust gas is discharged into the exhaust pipe 4 through a pipeline and discharged to the outside. However, the amount of exhaust gas discharged by the incinerator for exhaust gas treatment will change with the progress and time of industrial production, and the exhaust pipe 4 is set at a fixed height, and dust adsorption and atomization nozzles are installed in the exhaust pipe 4 to cool the exhaust gas while being able to cool the exhaust gas. The dust particles in the air are collected, and industrial production will also have peak and trough periods, which will lead to changes in the amount of exhaust gas emissions. The exhaust pipe 4 with a fixed height has been used to discharge the exhaust gas. The atomizing nozzles arranged in the exhaust pipe 4 will continuously spray cooling and dust removal water outward. During the trough period of industrial production, the exhaust gas discharged is less, and no excessive cooling and dust removal water is required. However, all the atomizing nozzles in the exhaust pipe 4 are continuously opened, which will cause a waste of resources. The manual control of the water spraying amount of the atomizing nozzles will increase the workload of the staff, and the water discharge amount of the atomizing nozzles cannot be automatically adjusted. 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; 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. 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; 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. The baffle 7 is set to be a disc with a right-angle trapezoidal cross section, and the inclined surface is facing downward, and a fish scale deflector 15 is set on the inclined surface in the same direction as the inclined surface, and the fish scale deflector 15 is installed in the rotating hole 16 through the rotating shaft 17. When the baffle 7 is in the normal closed state, the fish scale deflector 15 is in an outward pop-up state due to the effect of gravity; When the exhaust gas volume is small, the exhaust gas will also have a certain impact force on the fish scale guide plate 15, and the fish scale guide plate 15 is flipped toward the side of the baffle plate 7 to provide a guiding effect for the exhaust gas, and the exhaust gas is guided to the smoke guide pipe 6 and the smoke outlet pipe 5 arranged on the side below the corresponding baffle plate 7 and discharged outward; When the amount of exhaust gas is large, the force of the exhaust gas impacting upward is large and rapid, so the exhaust gas will quickly fill the position of the fish scale guide plate 15 close to the baffle 7 to impact the baffle 7 upward, and the fish scale guide plate 15 will only flip upward to a small extent or even not flip at all, but will provide a certain flow resistance effect to the exhaust gas, thereby amplifying the impact force of the exhaust gas on the baffle 7, and thus impacting the baffle 7 upward to open it.
