Description

Technical Field

[0001] The present invention relates to the technical field of RTO, and more specifically, to a rotary RTO. Background Art

[0002] RTO is a regenerative thermal oxidizer. By heating the regenerator, the waste gas is brought close to the thermal oxidation temperature, and then the waste gas enters the combustion chamber for thermal oxidation. The temperature of the oxidized gas rises, and the organic matter is basically converted into carbon dioxide and water. The purified gas passes through another regenerator, the temperature drops, and after reaching the emission standard, it can be discharged. Existing rotary RTOs can basically meet the daily use requirements, but there are still some deficiencies that need to be improved.

[0003] During the actual application process, RTO will produce carbon dioxide and water after thermal oxidation treatment of the waste gas. Since the internal temperature of the RTO is extremely high, the water will evaporate into water vapor. In order to improve the heat recovery efficiency of the regenerator, general rotary RTOs are designed with extremely strong sealing performance. The long-term retention of water vapor causes extremely high internal pressure in the RTO, which may lead to the reverse flow of waste gas and high risk. For this reason, we propose a rotary RTO to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a rotary RTO to solve the problem of reverse flow of waste gas caused by extremely high internal pressure in the RTO due to the long-term retention of water vapor as mentioned in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A rotary RTO, comprising an RTO body, a sparking device, an intake pipe, and an exhaust pipe. The sparking device is arranged at the upper left end of the RTO body, the intake pipe is arranged at the lower left end of the RTO body, and the exhaust pipe is arranged at the lower right end of the RTO body. The RTO body is connected to four groups of baffles through a telescopic device, and a sealing plate is inserted into the top of the RTO body, and the sealing plate is connected to the RTO body through a lifting device.

[0006] Preferably, the telescopic device includes a first telescopic rod, a first spring, and a second telescopic rod. Eight groups of first telescopic rods are welded on the outer surface of the RTO body, and first springs are arranged inside the first telescopic rods. One end of each first spring is welded to the first telescopic rod, and the other end of each first spring is welded to the second telescopic rod. The second telescopic rods all penetrate the outer surface of the first telescopic rods, and baffles are welded on the outer sides of the second telescopic rods.

[0007] Preferably, the lifting device includes a connecting plate, a collar, a collar groove, a limiting rod and a second spring. The top of the sealing plate is welded with the connecting plate, and the connecting plate is welded with collars around it. The collars are all embedded in the collar groove, and two groups of limiting rods are welded on the inner wall of the collar groove. The limiting rods all penetrate the surface of the collar, and the second springs are sleeved on the surface of the limiting rods. One end of each second spring is welded to the collar, and the other end of each second spring is welded to the top of the inner wall of the collar groove. One end of the collar groove is welded with the RTO body.

[0008] Preferably, the second telescopic rods are all cylindrical, circular holes are formed on the outer surface of the first telescopic rods, and the diameter of the cylindrical surface of the second telescopic rods is the same as the inner diameter of the circular holes formed on the outer surface of the first telescopic rods.

[0009] Preferably, the baffles are annularly distributed on the surface of the RTO body with the RTO body as the center.

[0010] Preferably, the collars are all rectangular, the collar grooves are all rectangular grooves, and the size of the rectangle of the collars is the same as the size of the inner wall of the rectangular grooves of the collar grooves.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The rotary RTO is provided with a sealing plate, a connecting plate, a collar, a collar groove, a limiting rod and a second spring. By starting the RTO body, the high-pressure water vapor inside the RTO body pushes the sealing plate to move upward. The sealing plate drives the connecting plate to move, and the connecting plate drives the collar inside the collar groove, so as to achieve the purpose of forming an exhaust hole in the RTO body, solve the problem that the water vapor stays for a long time, resulting in extremely high air pressure inside the RTO and causing the waste gas to flow back, and at the same time, it can also release the impact force generated by the deflagration of the waste gas inside the RTO body, reduce the damage to the RTO body, and improve the practicability of the device.

[0014] The rotary RTO is provided with a first telescopic rod, a first spring, a second telescopic rod and a baffle. By squeezing the baffle, the baffle drives the second telescopic rod to squeeze the first spring. The first spring generates elastic deformation due to the extrusion of the second telescopic rod, so that the first spring buffers the force of squeezing the baffle, so as to achieve the purpose of avoiding direct external impact on the RTO body, preventing the tank body of the RTO body from cracking due to external impact. At the same time, since the temperature of the RTO body is extremely high, the baffle can also play a role in preventing people from accidentally touching it, improving the safety of the device.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1-5 , an embodiment provided by the present invention:

[0023] A rotary RTO, comprising an RTO body 1, a sparking device 2, an intake pipe 3 and an exhaust pipe 4. The sparking device 2 is arranged at the upper left end of the RTO body 1, the intake pipe 3 is arranged at the lower left end of the RTO body 1, and the exhaust pipe 4 is arranged at the lower right end of the RTO body 1. The RTO body 1 is connected to four groups of baffles 8 through a telescopic device. The telescopic device includes a first telescopic rod 5, a first spring 6 and a second telescopic rod 7. Eight groups of first telescopic rods 5 are welded on the outer surface of the RTO body 1, and the first springs 6 are arranged inside the first telescopic rods 5. One end of each first spring 6 is welded on the first telescopic rod 5, and the other end of each first spring 6 is welded on the second telescopic rod 7. The second telescopic rods 7 all penetrate through the outer surface of the first telescopic rods 5. The second telescopic rods 7 are all cylindrical. Circular holes are formed on the outer surface of the first telescopic rods 5. The diameter of the cylindrical surface of the second telescopic rod 7 is the same as the inner diameter of the circular holes formed on the outer surface of the first telescopic rod 5. Since the diameter of the cylindrical surface of the second telescopic rod 7 is the same as the inner diameter of the circular holes formed on the outer surface of the first telescopic rod 5, the second telescopic rod 7 can move inside the first telescopic rod 5, so as to achieve the purpose of adjusting the position. Baffles 8 are welded on the outer sides of the second telescopic rods 7. The baffles 8 are annularly distributed on the surface of the RTO body 1 with the RTO body 1 as the center, so that the baffles 8 can completely cover the surface of the RTO body 1, thus achieving the purpose of protecting the RTO body 1 and the user.

[0024] A sealing plate 9 is inserted at the top of the RTO body 1, and the sealing plate 9 is connected to the RTO body 1 through a lifting device. The lifting device includes a connecting plate 10, a collar 11, a collar groove 12, a limiting rod 13 and a second spring 14. The connecting plate 10 is welded to the top of the sealing plate 9, and the connecting plate 10 is welded with collars 11 around it. The collars 11 are all embedded inside the collar grooves 12. The collars 11 are all set as rectangles, and the collar grooves 12 are all set as rectangular grooves. The size of the rectangle set by the collar 11 is the same as the inner wall size of the rectangular groove set by the collar groove 12. Since the size of the rectangle set by the collar 11 is the same as the inner wall size of the rectangular groove set by the collar groove 12, the collar 11 can move inside the collar groove 12, so as to achieve the purpose of changing the position. And two groups of limiting rods 13 are welded to the inner walls of the collar grooves 12. The limiting rods 13 all penetrate the surface of the collar 11. The limiting rods 13 are all set as another cylindrical shape. Another round hole is opened on the surface of the collar 11. The diameter of the surface of the other cylindrical shape set by the limiting rod 13 is the same as the inner diameter of the other round hole opened on the surface of the collar 11. Since the diameter of the surface of the other cylindrical shape set by the limiting rod 13 is the same as the inner diameter of the other round hole opened on the surface of the collar 11, the collar 11 can move on the surface of the limiting rod 13 under the restriction of the limiting rod 13, so as to achieve the purpose of avoiding shaking during the movement. The limiting rods 13 are all sleeved with second springs 14, and one end of each second spring 14 is welded to the collar 11, and the other end of each second spring 14 is welded to the top of the inner wall of the collar groove 12, and one end of the collar groove 12 is welded to the RTO body 1.

[0025] Working principle: When there is an external force impacting the RTO body 1, the baffle 8 bears the outside. The baffle 8 moves inward due to the external force, causing the baffle 8 to drive the second telescopic rod 7 to move. The second telescopic rod 7 squeezes the first spring 6. The first spring 6 generates elastic deformation due to the squeezing of the second telescopic rod 7, causing the first spring 6 to drive the second telescopic rod 7 to move inward of the first telescopic rod 5. The first spring 6 buffers the external force borne by the baffle 8, so as to avoid the deformation or rupture of the outer wall of the RTO body 1 caused by the external force impact.

[0026] When the RTO body 1 needs to be used, the waste gas enters the inside of the RTO body 1 through the intake pipe 3, and then the waste gas is ignited by the ignition device 2, so that the waste gas undergoes thermal oxidation inside the RTO body 1 and generates water and carbon dioxide. Under the action of high temperature, the water evaporates into water vapor. Since the inner wall temperature of the RTO body 1 is high, the water vapor cannot condense on the inner wall surface of the RTO body 1. The water vapor accumulates inside the RTO body 1 to generate a high-intensity air pressure, which pushes the sealing plate 9. The sealing plate 9 drives the connecting plate 10 to move, and the connecting plate 10 drives the collar 11 to move under the restriction of the limiting rod 13, so that the collar 11 squeezes the second spring 14. The second spring 14 undergoes elastic deformation due to the squeezing of the collar 11, so that the sealing plate 9 moves out of the circular hole opened at the top of the RTO body 1. The water vapor is discharged through the exhaust hole generated by the sealing plate 9 and the RTO body 1, so that the air pressure is not sufficient to lift the sealing plate 9, and the sealing plate 9 stops squeezing the second spring 14. The elastic deformation of the second spring 14 is restored, so that the second spring 14 pushes the collar 11 to move inside the collar groove 12. The collar 11 drives the connecting plate 10 to move, so that the connecting plate 10 drives the sealing plate 9 to insert into the circular hole opened at the top of the RTO body 1, and the sealing plate 9 is reset.
