Description

Technical Field

[0001] This application relates to the technical field of rotary RTO combustion devices, and in particular to a rotary RTO combustion device suitable for various exhaust gases. Background Technology

[0002] Rotary RT is a highly efficient organic waste gas treatment device. Its basic principle is to use a ceramic heat storage body to store heat. When organic waste gas enters the device, it first passes through a preheated heat storage body, and the waste gas is heated to near the oxidation temperature. Then, an oxidation reaction takes place in the combustion chamber. Organic matter reacts with oxygen at high temperature and is converted into harmless substances such as carbon dioxide and water. The high-temperature gas after oxidation then passes through another heat storage body, transferring heat to the heat storage body before being discharged. In this way, heat recovery and utilization are achieved, and the heat recovery efficiency can reach more than 95%.

[0003] A search revealed Chinese patent application CN202321677354.0, which discloses a rotary RTO regenerative thermal oxidizer device. The device includes a regenerative chamber with a ventilation port connected to its bottom surface via a cleaning port. A combustion chamber is connected to the side wall of the regenerative chamber via a flange ring. An observation window is provided on the side wall of the combustion chamber. A connecting pipe is connected to the side wall of the regenerative chamber via a quick-connect structure. This invention utilizes the quick-connect structure design. By holding a new connecting pipe and inserting one end into a fixed connecting pipe, pressing down on the buckle structure with both hands, the device grips the limiting clamp and pushes it towards the center, causing the sliding block to slide on the connecting block. This clamps the connecting pipe, allowing for quick replacement of the new connecting pipe, reducing worker workload and maintenance costs.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: While the above technical solutions can facilitate the replacement of gaskets or connecting pipes, in actual use, because they process different waste gases, the waste gases may have a corrosive effect on the gaskets, making them prone to breakage and leakage over time. Some waste gas leaks, such as those containing small amounts of volatile organic compounds (VOCs), may not have an obvious odor when the concentration is low. Moreover, the flow direction of the waste gas and the airflow conditions of the surrounding environment can also affect the detectability of the leak. Furthermore, the waste gas is quickly diluted or carried away by the surrounding normal ventilation airflow, making it even more difficult to detect the leak, thus affecting the air and the health of operators.

[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0023] This application discloses a rotary RTO combustion device suitable for various waste gases. For example... Figure 1-4 The diagram shows a rotary combustion furnace body 1. An air inlet pipe 2 is provided on one side of the rotary combustion furnace body 1. An external flange 3 is fixedly connected to one end of the air inlet pipe 2. Two sealing blocks 4 are fitted on the external flange 3. Locking mechanisms 5 are fixedly connected to both sides of the two sealing blocks 4.

[0024] A movable tube 6 is provided on the upper side of one of the two sealing blocks 4. A top pressure spring 7 is fixedly connected to the lower side of the inner wall of the movable tube 6. A piston 8 that cooperates with the movable tube 6 is fixedly connected to the upper end of the top pressure spring 7. A push-type alarm 9 is fixedly connected to the upper side of one of the two sealing blocks 4. A trigger rod 10 that cooperates with the push-type alarm 9 is fixedly connected to the upper side of the piston 8. An air extraction port 11 is provided on the upper side of one of the two sealing blocks 4 and on one side of the movable tube 6. A one-way valve 12 is fixedly connected to the inner wall of the air extraction port 11. A temperature detection component 13 is provided on the upper side of the rotary combustion furnace body 1.

[0025] Please see Figure 4 The locking mechanism 5 includes a tightening block 501 fixedly connected to both sides of the two sealing blocks 4, a movable groove 502 fixedly connected to the upper side of one of the two tightening blocks 501, a U-shaped clip 503 slidably fitted on the inner wall of the movable groove 502 and cooperating with the other of the two tightening blocks 501, and a limiting spring 504 fixedly connected between the U-shaped clip 503 and the movable groove 502. The limiting spring 504 presses the U-shaped clip 503, causing the U-shaped clip 503 to tighten the two tightening blocks 501. After tightening, it squeezes the sealing gasket 14, thereby sealing the two sealing blocks 4.

[0026] Please see Figure 2 The temperature detection component 13 includes an installation port 131 on the upper side of the rotary combustion furnace body 1, a temperature detector 132 fixedly connected to the inner wall of the installation port 131, an extension block 133 fixedly connected to the upper side of the rotary combustion furnace body 1, and a limiter 134 fixedly connected to the upper side of the extension block 133 and cooperating with the temperature detector 132. The temperature detector 132 can detect the internal temperature of the rotary combustion furnace body 1. The temperature detector 132 is a resistance thermometer that can be used for high temperature detection. After detection, the data is transmitted to the limiter 134 for display, so that personnel can distinguish the internal temperature and control the combustion temperature for different exhaust gases.

[0027] Please see Figure 1 and Figure 4Two sealing blocks 4 are fixedly connected to a sealing gasket 14 on their adjacent sides. Both sealing gaskets 14 are in contact with the external flange 3 and the air inlet pipe 2. When the sealing block 4 is sealed, it squeezes the sealing gasket 14 to achieve partial sealing between the air inlet pipe 2 and the external flange 3. Since the sealing position will not come into contact with the exhaust gas, its service life is relatively long.

[0028] Please see Figure 2 The outer flange 3 has a snap-fit ​​groove 15 on one side, and a compression gasket 16 is provided on the inner wall of the snap-fit ​​groove 15. By snapping the compression gasket 16 into the snap-fit ​​groove 15, the sealing degree of the outer flange 3 after it is connected to the corresponding external flange can be improved.

[0029] Please see Figure 3 The upper side of the one-way valve 12 is threaded with a sealing cap 17. Multiple protective grooves 18 are provided on the outer side of the sealing cap 17. The sealing cap 17 covers the upper side of the one-way valve 12 to seal the one-way valve 12. The protective grooves 18 can increase the friction of the fingers when twisting the sealing cap 17.

[0030] Please see Figure 4 Two U-shaped clips 503 are fixedly connected to the upper side of a force plate 19. An anti-slip pad 20 is provided on the adjacent side of the two force plates 19. When operating the U-shaped clips 503, the force plate 19 facilitates the application of force by the operator, and the anti-slip pad 20 can reduce the reaction force of the force plate 19 when applying force, thus improving the comfort of operation.

[0031] The implementation principle of a rotary RTO combustion device applicable to various waste gases according to an embodiment of this application is as follows: During use, the external flange 3 is connected to corresponding external accessories, and a compression gasket 16 is used to seal between them. After connection, two sealing blocks 4 are snapped onto the outside of the external flange 3 and the air inlet pipe 2, and a sealing gasket 14 is used to seal between them, forming an independent sealed space outside the external flange 3 between the two sealing blocks 4. Then, a vacuum is drawn from the exhaust port 11 to the inside of the sealing blocks 4, so that the sealed space within the sealed blocks 4... The negative air pressure is generated, which causes the piston 8 to slide downward inside the movable tube 6. When a leak occurs in the connection part of the external flange 3 or between the two sealing blocks 4, the negative pressure environment inside the sealing block 4 will be destroyed. Once destroyed, the top pressure spring 7 will squeeze the piston 8 to move upward, and the top pressure trigger rod 10 will be squeezed with the press-type alarm 9, thereby realizing the alarm of the press-type alarm 9. This allows the on-site staff to receive the alarm information immediately, so that they can take measures quickly to avoid environmental pollution, reduce the risk of accidents, and improve the safety of personnel at work.

[0032] The temperature inside the rotary combustion furnace body 1 is detected by the temperature detector 132 in the installation port 131, and then the temperature is displayed on the limiter 134 to control the temperature inside the rotary combustion furnace body 1. This allows for matching the appropriate temperature to different chemical components of the waste gas, making the device suitable for combustion of different waste gases.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
