Description

Technical Field

[0001] The utility model relates to the technical field of organic waste gas treatment, in particular to an organic waste gas catalytic combustor. Background Technique

[0002] Organic waste gas catalytic combustion is a technology for treating organic waste gas. It oxidizes and decomposes organic substances in the waste gas into harmless carbon dioxide and water through a catalyst. The catalyst in the process accelerates the reaction and reduces the temperature required for combustion, thus saving energy. This method is commonly used in industrial production and can effectively reduce environmental pollution caused by waste gas.

[0003] An organic waste gas catalytic combustor with the publication number of CN221222730U, by rotating the smoke inlet pipe by hand, there are limiting grooves respectively opened on the side wall of the fixed connection seat and the fixed connection block, and under the condition that the limiting grooves are respectively connected with the fixed connection block in a sliding connection manner, the smoke inlet pipe is removed. Then, press the connecting rod with a finger, so that the connecting rod presses the driving spring through the baffle, thereby enabling the connecting block to slide in the chute, and further enabling the connecting rod to slide in the connecting hole, so that the connecting hole is disengaged from the limit. Then, hold the limiting connecting plate with a hand and drag it outwards, so that the filter cover is dragged out of the smoke inlet pipe, and then a new filter cover and activated carbon are replaced, thereby improving the filtering effect and the efficiency of waste gas treatment.

[0004] When the above-mentioned patent needs to replace the filter cover or clean the blocked impurities, it is necessary to remove the entire smoke inlet pipe from the fixed connection seat before operation. After the smoke inlet pipe is removed, the organic waste gas cannot enter the combustor, affecting the normal operation of the organic waste gas catalytic combustor. For this reason, we propose an organic waste gas catalytic combustor. Content of the Utility Model

[0005] The purpose of the utility model is to provide an organic waste gas catalytic combustor to solve the problem that when the filter cover is removed to clean impurities or replaced, the organic waste gas cannot enter the combustor, thus affecting the normal operation of the organic waste gas catalytic combustor as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Embodiment 1:

[0022] Please refer to Figures 1-3 , the present invention provides a technical solution: an organic waste gas catalytic combustor, including a combustion furnace main body 1, an air outlet pipe 2 is provided on the combustion furnace main body 1, and an air inlet pipe 3 is connected to the bottom end of the side wall of the combustion furnace main body 1. Two groups of rear baffles 6 are installed on the inner wall of the air inlet pipe 3. A fixed circular frame 4 is provided at the outer ends of the two groups of rear baffles 6, and a filter screen 5 is connected in the fixed circular frame 4. A fixed box 14 is installed on the side of the fixed circular frame 4 close to the combustion furnace main body 1. A battery pack 17 and a servo motor 15 are provided in the fixed box 14. A controller 18 is connected to the outer side wall of the fixed box 14, and a rotating shaft is connected to the output end of the servo motor 15. The rotating shaft penetrates through the fixed circular frame 4, and a cleaning scraper 16 is provided on the outer wall of the bottom of the rotating shaft; the combustion furnace main body 1 is an existing device, and organic waste gas catalysis combustion is an existing technology. The specific structure and working principle will not be elaborated here. The electrical end of the servo motor 15 is electrically connected to the battery pack 17 and the electrical end of the controller 18. A through hole adapted to the rotating shaft is opened in the fixed circular frame 4 and the filter screen 5. The operation of the servo motor 15 can drive the cleaning scraper 16 to rotate on the outer side wall of the filter screen 5. The rotation of the cleaning scraper 16 can clean the clogged impurities on the filter screen 5 in real time, which can clean the impurities in real time while not affecting the entry of organic waste gas, and ensure the working efficiency of the organic waste gas catalytic combustor;

[0023] Both side walls of the intake pipe 3 are provided with through openings 7. On both outer walls of the intake pipe 3 and on one side of the through openings 7, U-shaped frames 8 are connected. A limiting component for limiting the fixed circular frame 4 is arranged inside the U-shaped frame 8; the U-shaped frame 8 is fixedly connected to the outer wall of the intake pipe 3. Through the action of the limiting component and in cooperation with the action of the rear stop strip 6 (fixedly installed on the inner wall of the intake pipe 3), the quick disassembly and assembly of the filter screen 5 in the fixed circular frame 4 and the inner wall of the intake pipe 3 are realized, which is convenient for the installation in the early stage and the maintenance in the later stage, and improves the work efficiency.

[0024] Among them, preferably, the limiting component includes an operating rod 9. The operating rod 9 is slidably connected inside the U-shaped frame 8, and one end of the operating rod 9 close to the through opening 7 is connected with a positioning block 19 adapted to the through opening 7. A return spring 10 is sleeved on the outer wall of the operating rod 9, and the return spring 10 is located between the inner wall of the U-shaped frame 8 and the positioning block 19;

[0025] The operating rod 9 is fixedly connected to the positioning block 19. The cross section of the positioning block 19 is T-shaped. When the fixed circular frame 4 and the filter screen 5 are installed in the intake pipe 3, the two operating rods 9 are pulled outwards, so that the positioning block 19 is located inside the U-shaped frame 8 through the through opening 7, and the return spring 10 is in a compressed state. At this time, the fixed circular frame 4 can slide into the intake pipe 3. The two rear stop strips 6 limit the rear end of the fixed circular frame 4. Then, the operating rod 9 is released, and the compressed return spring 10 automatically returns to its original position. The positioning block 19 moves and passes through the through opening 7 to be located on the side wall of the fixed circular frame 4, that is, the position of the fixed circular frame 4 is limited, and the installation of the filter screen 5 in the fixed circular frame 4 is completed. When disassembling, the operating rod 9 is pulled outwards, so that the positioning block 19 passes through the through opening 7 and moves away from the side wall of the fixed circular frame 4. After the fixed circular frame 4 is no longer restricted, it can be taken out from the inner wall of the intake pipe 3.

[0026] Preferably, a positioning hole 11 is arranged through the operating rod 9. A side plate 12 is connected to the outer wall of the U-shaped frame 8, and a positioning slide rod 13 adapted to the positioning hole 11 is slidably connected inside the side plate 12; when the operating rod 9 is pulled outwards and the positioning block 19 is located inside the U-shaped frame 8, at this time, the return spring 10 is compressed, and the positioning hole 11 is aligned with the positioning slide rod 13. In order to prevent the positioning block 19 from moving due to the elasticity of the return spring 10, the positioning slide rod 13 inside the side plate 12 moves to be connected with the positioning hole 11, that is, the position of the operating rod 9 is fixed, and the position of the positioning block 19 is prevented from sliding due to the elasticity of the return spring 10.

[0027] Preferably, the cleaning scraper 16 is attached to the outer wall of the filter screen 5.

[0028] Preferably, a pull ring is installed at one end of the operating rod 9 away from the positioning block 19, and an anti-slip rubber sleeve is sleeved on the hand-held end of the pull ring; the pull ring facilitates the pulling of the operating rod 9, and the anti-slip rubber sleeve plays an anti-slip role to avoid slipping off when holding the pull ring.

[0029] Embodiment 2:

[0030] Referring to Figure 2 , the difference between this embodiment and the first embodiment is that anti-slip pads are provided on the surfaces of the positioning block 19 and the rear stop bar 6 close to the fixed circular frame 4; the anti-slip pads play an anti-slip role and improve the stability when the fixed circular frame 4 is installed in the intake pipe 3.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
