Description

Technical Field

[0001] This utility model relates to the field of combustion furnace technology, specifically to an RTO catalytic combustion furnace that is easy to clean. Background Technology

[0002] RTO catalytic combustion furnace is a high-efficiency organic waste gas treatment equipment that combines regenerative thermal oxidation (RTO) and catalytic combustion technologies. It achieves efficient removal of organic pollutants through three stages: preheating, combustion, and heat storage.

[0003] A search revealed CN214275774U, which discloses an easy-to-clean RTO catalytic combustion furnace, including a furnace body. Exhaust pipes are installed on the furnace body, and a fixing structure is provided between the exhaust pipes. The fixing structure includes a first connecting plate, a groove, a second connecting plate, a locking block, a first connecting sleeve, a first mounting plate, a second connecting sleeve, a second mounting plate, a clamping groove, fastening bolts, and nuts. The furnace body has a movable door and a movable frame. The movable frame includes a fixed plate, a sliding groove, a sliding plate, movable legs, and fastening screws, and a fan is mounted on the movable frame. This utility model utilizes the fixing structure to securely install the exhaust pipes, making installation and disassembly convenient. It offers high stability after installation and facilitates cleaning. The movable frame also allows for the fixing of the fan, facilitating adjustment of the fan's position and making installation flexible and convenient.

[0004] In practical applications, exhaust pipes are generally equipped with filters. However, in existing technologies, exhaust pipes can only be disassembled and cleaned when the catalytic combustion furnace is shut down, which reduces work efficiency. Moreover, if the exhaust pipe is replaced without shutting down the furnace, unfiltered flue gas will leak out, thus polluting the environment. Therefore, this needs to be improved.

[0013] Beneficial effects

[0014] This invention provides an RTO catalytic combustion furnace that is easy to clean, and has the following beneficial effects:

[0015] 1. This easy-to-clean RTO catalytic combustion furnace, by setting up a U-shaped tube, mounting base, flue, exhaust gas blocking mechanism and starting component, allows for the replacement and cleaning of the flue without stopping the machine by switching between two flue pipes, thereby improving work efficiency.

[0016] 2. This easy-to-clean RTO catalytic combustion furnace, through the setting of a waste gas sealing mechanism and a starting component, uses a spring to apply elastic force to the movable cylinder, which slides upward along the inner wall of the fixed cylinder, thereby causing the first exhaust port and the second exhaust port to be misaligned. This ensures that the flue gas inside the U-shaped pipe will not leak out when the exhaust stack is removed.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: an easy-to-clean RTO catalytic combustion furnace, including a combustion furnace body 1. A waste gas inlet pipe 2 and a support frame 3 are arranged on the left side of the combustion furnace body 1. A pumping mechanism 4 for supplying air into the combustion furnace body 1 is arranged on the surface of the support frame 3. An exhaust pipe 5 is arranged on the upper surface of the combustion furnace body 1. A U-shaped pipe 6 is fixedly connected to the upper end of the exhaust pipe 5. Mounting seats 7 are fixedly connected to the outer surfaces of both ends of the U-shaped pipe 6. Annular locking grooves 8 are formed on the surfaces of both mounting seats 7. The inner wall of the annular snap-fit ​​groove 8 can be detachably installed with a smoke exhaust pipe 9. The inner walls of both ends of the U-shaped pipe 6 are provided with exhaust gas sealing mechanisms 10 to prevent smoke leakage. The inner walls of the two smoke exhaust pipes 9 are provided with a starting component 11 to open the exhaust gas sealing mechanism 10. By setting up the U-shaped pipe 6, mounting base 7, smoke exhaust pipe 9, exhaust gas sealing mechanism 10 and starting component 11, the two smoke exhaust pipes 9 can be switched to be used, and the smoke exhaust pipes 9 can be replaced and cleaned without stopping the machine, which helps to improve work efficiency.

[0024] The air pumping mechanism 4 includes an air intake pump 12 and an air delivery pipe 13. The air delivery pipe 13 is located at the output end of the air intake pump 12. The air intake pump 12 is fixedly installed on the surface of the support frame 3, and the air delivery pipe 13 is connected to the combustion chamber inside the combustion furnace body 1. By setting up the air pumping mechanism 4 and utilizing the operation of the air intake pump 12, outside air can be introduced into the combustion chamber inside the combustion furnace body 1 through the air delivery pipe 13, which can help to fully combust the exhaust gas.

[0025] The inner wall of the exhaust stack 9 is provided with a filter layer 14. By setting the filter layer 14, the gas entering the exhaust stack 9 can be filtered before being discharged to the outside.

[0026] The exhaust pipe 9 has locking blocks 15 on both the front and rear sides of its outer surface. The surface of the locking blocks 15 has a locking groove. The mounting base 7 has locking rings 16 rotatably connected to both the front and rear sides of its outer surface. The locking rings 16 can fit into the locking grooves. By setting the locking rings 16 and using the locking rings 16 to fit into the locking grooves on the surface of the locking blocks 15, the exhaust pipe 9 can be quickly installed and disassembled. The installation process of the exhaust pipe 9 does not require the use of bolts, which makes it more convenient.

[0027] The exhaust gas sealing mechanism 10 includes a strip support plate 17, a spring 18, a movable cylinder 19, and a fixed cylinder 20. The strip support plate 17 is fixedly connected to the inner wall of the U-shaped tube 6, the spring 18 is fixedly connected to the surface of the strip support plate 17, the movable cylinder 19 is fixedly connected to the upper end of the spring 18, and the fixed cylinder 20 is fixedly connected to the inner wall of the end of the U-shaped tube 6. The movable cylinder 19 is slidably connected to the inner wall of the fixed cylinder 20. The outer surface of the movable cylinder 19 has multiple first exhaust holes 21, and the inner wall of the fixed cylinder 20 has multiple second exhaust holes 22. The multiple first exhaust holes 21 and the multiple second exhaust holes 22 can overlap each other. The starting component 11 includes a T-shaped rod 23 and a strip-shaped contact plate 24. The strip-shaped contact plate 24 is fixedly connected to the inner wall of the movable cylinder 19, and the T-shaped rod 23 is fixedly connected to the inner wall of the exhaust pipe 9. Rod 23 corresponds to strip-shaped contact plate 24. Multiple first exhaust holes 21 and multiple second exhaust holes 22 are arranged in a ring array. By setting exhaust gas blocking mechanism 10 and starting component 11, spring 18 applies elastic force to movable cylinder 19. Movable cylinder 19 will slide upward along the inner wall of fixed cylinder 20, thereby causing the first exhaust holes 21 and second exhaust holes 22 to be misaligned. This ensures that the flue gas in U-shaped pipe 6 will not leak out when the exhaust pipe 9 is removed. When installing exhaust pipe 9, T-shaped rod 23 is used to press down strip-shaped contact plate 24, which can compress spring 18. Movable cylinder 19 will move downward, thereby achieving the overlap of first exhaust holes 21 and second exhaust holes 22. This facilitates the entry of flue gas into exhaust pipe 9 from the upper opening of U-shaped pipe 6, effectively preventing the leakage of flue gas and pollution of the external environment.

[0028] Working principle: When the easy-to-clean RTO catalytic combustion furnace is in use, the exhaust gas is introduced into the combustion furnace body 1 through the exhaust gas inlet pipe 2. Then, the air pumping mechanism 4 is turned on to pump air into the combustion chamber in the combustion furnace body 1. After the exhaust gas is fully combusted, it will be discharged from the exhaust pipe 5 into the U-shaped pipe 6. Under working conditions, only one exhaust pipe 9 is installed at the upper end of the U-shaped pipe 6. If it is necessary to clean the exhaust pipe 9, another clean exhaust pipe 9 can be inserted into the annular snap-fit ​​groove 8. Then, the snap-fit ​​grooves on the surface of the snap-fit ​​ring 16 and the snap-fit ​​block 15 are used to fix the exhaust pipe 9. After the exhaust pipe 9 is fixedly installed, the T-shaped rod 23 will press down the strip-shaped contact plate 24, and the movable cylinder 19 will move downward accordingly, thereby realizing the overlap of the first exhaust hole 21 and the second exhaust hole 22. This provides convenience for the flue gas to enter the exhaust pipe 9 from the opening at the upper end of the U-shaped pipe 6, effectively avoiding the leakage of flue gas and pollution of the external environment.

[0029] Then rotate the retaining ring 16 on the outside of the exhaust pipe 9 that needs to be cleaned. When the retaining ring 16 is away from the slot of the retaining block 15, the exhaust pipe 9 can be pulled out from the annular retaining groove 8. After the exhaust pipe 9 is disassembled, the spring 18 applies elastic force to the movable cylinder 19, and the movable cylinder 19 will slide upward along the inner wall of the fixed cylinder 20, so that the first exhaust hole 21 and the second exhaust hole 22 are misaligned with each other. Thus, the smoke in the U-shaped pipe 6 will not leak out when the exhaust pipe 9 is removed, ensuring that the external environment will not be polluted by the smoke. The exhaust pipe 9 can be easily cleaned after disassembly.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
