Technical Field
[0001] This invention relates to the field of combustion exhaust gas treatment technology, and in particular to a circulating device for treating gas exhaust gas combustion. Background Technology
[0002] Existing gas combustion treatment recycling devices possess excellent compatibility, adapting to the combustion needs of both gas and biomass fuels. They enable convenient fuel type switching or simultaneous treatment, ensuring stable and efficient combustion. By optimizing the combustion chamber structure and gas supply system, these devices fully meet the requirements of different fuel characteristics, ensuring complete combustion of both gas and biomass fuels, reducing energy waste and pollutant emissions. Under actual operating conditions, their intelligent fuel identification and switching functions further expand the application scope of the devices, enabling flexible application in various industrial production scenarios and providing strong support for waste gas treatment and energy recovery in multiple industries.
[0003] Methane, the main component of gas exhaust, is a highly efficient and clean energy source. However, its flammable and explosive properties impose strict requirements on combustion treatment. The composition and calorific value of gas exhaust from different sources vary significantly. During combustion, the air-fuel ratio must be precisely controlled to ensure complete combustion and reduce pollutant emissions. Biomass fuel exhaust has a more complex composition, containing not only carbon, hydrogen, and oxygen but also impurities such as nitrogen and sulfur. Its combustion products are relatively complex, and the risk of pollutant emissions is higher. Existing burners typically require different burner nozzles to be replaced according to the characteristics of these two types of exhaust gases in order to adapt to their combustion characteristics.
[0004] However, a significant problem exists in burners currently on the market: nozzle replacement requires manual operation. The manual nozzle replacement process is cumbersome, time-consuming, and labor-intensive, which greatly affects the efficiency of exhaust gas treatment. In actual operation, facing the diverse needs of gas and biomass fuel exhaust gas, frequent manual intervention increases the risk of operational errors, which may lead to unstable combustion or even safety hazards.

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.
[0021] In actual use, it was found that the burners 2 currently on the market generally have a significant problem: the replacement of nozzle 3 requires manual operation. The manual replacement of nozzle 3 is cumbersome, time-consuming and labor-intensive, which greatly affects the efficiency of exhaust gas treatment. In actual operation, facing the diverse needs of gas and biomass fuel exhaust gas, frequent manual intervention increases the risk of operational errors, which may lead to unstable combustion or even safety hazards. In order to solve the above problems, the following structure was invented.
[0022] like Figures 1-10 The illustrated circulating device for treating gas waste gas combustion includes a combustion chamber 1, a burner 2, and a nozzle 3. The burner 2 is fixedly connected to the bottom of the compartment inside the combustion chamber 1. The output end of the burner 2 is fixedly connected to a connecting pipe 4, which penetrates the internal partition of the combustion chamber 1. The nozzle 3 is installed on the connecting pipe 4. Gas waste gas or biomass waste gas is discharged into the combustion chamber 1 through the pipe and then ignited and burned in the combustion chamber 1 by the burner 2. During this process, the heat energy generated by combustion can be used in other production processes, such as heating or power generation. Finally, the gas that meets the standards is discharged through the pipe. An inspection port is provided on the rear side of the combustion chamber 1, and an automatically opening lifting door 5 is provided on the inspection port. The lifting door 5 can be used to seal the inspection port to prevent gas leakage during the treatment process.
[0023] A replacement platform 6 is fixedly connected to the rear side of the combustion chamber 1. A slot is provided at the top of the connecting pipe 4. A plug ring 7 for inserting into the slot is fixedly connected to the bottom of the nozzle 3. Four fixed frames 8 are fixedly connected at equal intervals on the outer wall of the connecting pipe 4. A T-shaped frame 9 is slidably connected to the inner side of each of the four fixed frames 8. A limit groove 10 is provided on the outer wall of the plug ring 7 relative to the position next to the T-shaped frame 9. A limiting mechanism for limiting the position of the T-shaped frame 9 is provided on the fixed frame 8. A replacement mechanism for replacing the nozzle 3 is provided on the replacement platform 6. The limiting mechanism includes limiting frames 11, four of which are slidably connected to the inner side of the T-shaped frame 9. The side wall of the fixed frame 8 has a sliding groove for the sliding of the limiting frames 11. The inner side of the fixed frame 8 has several right-angled grooves 12 with inclined surfaces at equal intervals. The side of the limiting frame 11 near the inclined surface of the right-angled groove 12 is set as a smooth arc surface. The inner side of the fixed frame 8 and the side wall of the T-shaped frame 9 are fixedly connected to a return spring 13. The inner side of the T-shaped frame 9 is fixedly connected to the inner side of the limiting frame 11. The side plate 14 is fixedly connected to the inner side of the limiting frame 11. The side plate 14 and the inner side of the limiting frame 11 are fixedly connected to a limiting spring 15. The top of the T-shaped frame 9 is fixedly connected to an upper right-angled block 16 with an inclined surface. The side wall of the limiting frame 11 has a squeezing groove 17 with an inclined side wall. The outer wall of the nozzle 3 has a pair of positioning grooves 32 symmetrically opened. The replacement mechanism includes a U-shaped frame 19. A pair of horizontal electric telescopic cylinders 20 are fixedly connected to the side wall of the replacement table 6. The U-shaped frame 19 is fixedly connected between the output ends of the horizontal electric telescopic cylinders 20. A horizontal frame 21 is slidably connected to the inner side of the U-shaped frame 19. A pair of semi-circular rings 22 are slidably connected to the inner side of the horizontal frame 21. A horizontal groove and a vertical groove are opened at the top of the semi-circular rings 22 relative to the position above the fixed frame 8. A horizontal plate 23 is slidably connected to the inner side of the horizontal groove. A vertical plate 24 is slidably connected to the inner side of the vertical groove. An upper connecting frame 25 is fixedly connected between the top ends of the vertical plates 24. A lower connecting frame 26 is fixedly connected between the top ends of the horizontal plates 23. An upper electric telescopic cylinder 27 and a lower electric telescopic cylinder 28 are fixedly connected to the bottom of the semi-circular rings 22 respectively. The output end of the upper electric telescopic cylinder 27 passes through the top of the semi-circular ring 22 and is fixedly connected to the bottom of the upper connecting frame 25. The output end of the lower electric telescopic cylinder 28 passes through the top of the semi-circular ring 22 and is fixedly connected to the bottom of the lower connecting frame 26. A bidirectional lead screw 29 is rotatably connected to the inner side of the horizontal frame 21. A drive motor 30 is fixedly connected to the side wall of the horizontal frame 21. The output end of the drive motor 30 passes through the inner side of the horizontal frame 21 and is fixedly connected to the side wall of the bidirectional lead screw 29. The bidirectional lead screw 29 is threaded through and connected to the inner side wall of the semi-circular ring 22. An upward electric telescopic cylinder 44 is fixedly connected to the top of the U-shaped frame 19. The output end of the upward electric telescopic cylinder 44 passes through the inner side of the U-shaped frame 19 and is fixedly connected to the top of the horizontal frame 21. The bottom sides of the horizontal plate 23 and the vertical plate 24 are both set as smooth arc surfaces to facilitate smoother extrusion of the T-shaped frame 9 and the extrusion groove 17. A positioning block 31 is fixedly connected to the inner side of the semi-circular ring 22. When nozzle 3 needs to be replaced for treating gas exhaust from different sources or biomass fuel exhaust, the detection module first checks whether there is any untreated residual gas in the combustion chamber 1. If the treatment has been completed, the lifting door 5 can be opened. Then, the horizontal electric telescopic cylinder 20 is started to drive the U-shaped frame 19 and the horizontal frame 21 into the combustion chamber 1. When the semi-circular ring 22 moves to both sides of the nozzle 3, the drive motor 30 is started to drive the bidirectional screw 29 to rotate, thereby driving the threaded semi-circular ring 22 to move towards the center, and then inserting the positioning block 31 into the positioning groove 32 on the nozzle 3. Then, the upper electric telescopic cylinder 27 is started to drive the upper connecting frame 25 to move down, and at the same time, drive multiple vertical plates 24 to move down, so that the vertical plates 24 are inserted into the extrusion groove 17 on the limiting frame 11. As the vertical plates 24 continue to move down, the arc surface at the bottom of the vertical plates 24 will push the inclined surface of the extrusion groove 17, causing the limiting frame 11 to slide. Then, the other end of the limiting frame 11 slides out of the right-angle groove 12, while the limiting spring 15 is gradually compressed, thereby releasing the position restriction on the T-shaped frame 9. Subsequently, under the elastic force of the return spring 13, the T-shaped frame 9 is pulled back to its original position, causing the T-shaped frame 9 to slide out of the limiting groove 10, releasing the position restriction on the insertion ring 7. During the resetting process of the T-shaped frame 9, the squeezing groove 17 on the limiting frame 11 will slide below the vertical plate 24. Then, the upward electric telescopic cylinder 44 can be controlled to start and drive the horizontal frame 21 to move upward, while simultaneously driving the nozzle 3 and the insertion ring 7 to move upward, thereby pulling the nozzle 3 out of the connecting pipe 4. The controllable horizontal electric telescopic cylinder 20 is reset, removing the U-shaped frame 19 from the combustion chamber 1. Then, the upward electric telescopic cylinder 44 is controlled to place the nozzle 3 onto the replacement table 6, and the drive motor 30 is controlled to reverse to release the clamping of the nozzle 3. The operator then removes the nozzle 3 and places the nozzle 3 to be replaced between the semicircular rings 22. The above operation is then repeated in reverse to install the nozzle 3 back. It should be noted that when the insertion ring 7 is inserted into the slot, the lower electric telescopic cylinder 28 needs to be started to drive the lower connecting frame 26 and the horizontal plate 23 to move down (at this time, the upper electric telescopic cylinder 27 is in the reset state). This causes the curved surface at the bottom of the horizontal plate 23 to press against the inclined surface of the upper right-angle block 16, moving the upper right-angle block 16 towards the center and driving the T-shaped frame 9 to move. This gradually stretches the return spring 13. During this process, the movement of the T-shaped frame 9 causes the limiting frame 11 to move. When the limiting frame 11 moves to the side of the right-angle groove 12, the inclined surface of the right-angle groove 12 presses against the curved surface of the side wall of the limiting frame 11, thus forcing the limiting frame 11 to slide into the T-shaped frame 9. Simultaneously, this stretches the limiting spring 15. Subsequently, when the limiting... When the retaining frame 11 moves to the next right-angle slot 12, the pressure on the retaining frame 11 is released. Then, under the elastic force of the retaining spring 15, the retaining frame 11 is pushed into the right-angle slot 12. This process is repeated until the side end of the T-shaped frame 9 is inserted into the retaining slot 10. At this time, the retaining frame 11 will be inserted into one of the right-angle slots 12. Then, the plane of the right-angle slot 12 fits with the plane of the retaining frame 11, which can now reset the retaining frame 11, thereby restricting the T-shaped frame 9 from resetting and ensuring the fixing effect on the insert ring 7. Finally, it can be retracted.
[0024] In summary, the above structural design enables automatic assembly and disassembly of nozzle 3, improving the convenience of the device.
[0025] To improve the sealing effect of the nozzle 3 installation, a sealing ring 18 is fixedly connected to the bottom end of the insert ring 7, the bottom end of the limiting groove 10 is inclined, and the side wall of the T-frame 9 is inclined. During the process of the lower electric telescopic cylinder 28 driving the T-frame 9 to insert into the limiting groove 10, the inclined surface of the side end of the T-frame 9 will press the inclined surface of the bottom end of the limiting groove 10. As the T-frame 9 gradually slides in, it presses the insert ring 7 to move downward, thereby causing the bottom end of the slot to press the sealing ring 18 at the bottom of the insert ring 7, ensuring the sealing performance when the insert ring 7 is connected to the slot, and ensuring the sealing performance when the burner 2 is connected to the nozzle 3.
[0026] Based on the above embodiments, it was found during use that when different models of nozzles 3 are replaced, the position of the igniter 35 also needs to be changed, so manual adjustment is required every time it is installed, which is quite cumbersome. To solve the above problem, the above structure has been further improved.
[0027] A telescopic frame 33 is fixedly connected to the inside of the combustion chamber 1. A telescopic rod 34 is slidably connected to the inside of the telescopic frame 33. An igniter 35 is fixedly connected to the side wall of the telescopic rod 34. A telescopic groove is opened inside the telescopic rod 34. A U-shaped rod 36 is slidably connected to the inside of the telescopic groove, and the bottom end of the U-shaped rod 36 passes through the bottom end of the telescopic rod 34. Several limiting grooves 37 are equidistantly opened inside the telescopic frame 33. A pressing rod 38 is fixedly connected to the side wall of the telescopic rod 34. Three upper springs 45 are fixedly connected between the top end of the pressing rod 38 and the top end of the telescopic groove. A lower spring 46 is fixedly connected between the inside of the telescopic frame 33 and the side wall of the telescopic rod 34. One of the semicircular rings 22 is fixedly connected to an upper plate 39 on its side wall. An adjustable electric telescopic cylinder 40 is fixedly connected to the bottom end of the upper plate 39. The output end of the adjustable electric telescopic cylinder 40 passes through the top end of the upper plate 39 and is fixedly connected to a lower right-angle block 41 with an inclined surface. A groove is opened on the side wall of the lower right-angle block 41. An unlocking plate 42 is slidably connected to the inside of the groove. A compression spring 43 is fixedly connected between the bottom end of the unlocking plate 42 and the bottom end of the groove. When the horizontal electric telescopic cylinder 20 moves the U-shaped frame 19 into the combustion chamber 1, and then when the upward electric telescopic cylinder 44 moves upward to pull the nozzle 3 out of the connecting pipe 4, it will drive the upper plate 39 and the lower right-angle block 41 to move below the telescopic frame 33. Then, the control adjustment electric telescopic cylinder 40 starts to drive the lower right-angle block 41 to move upward, which will first drive the unlocking plate 42 to move upward. Then, under the elastic force of the compression spring 43, the unlocking plate 42 pushes the U-shaped rod 36 to move upward (it is necessary that the elastic force of the compression spring 43 is greater than the elastic force of multiple upper springs 45), thereby causing the other end of the U-shaped rod 36 to slide out of the limiting groove 37, releasing the sliding restriction on the telescopic rod 34. Then, the inclined surface of the lower right-angle block 41 moves to below the compression rod 38 (at this time, if the telescopic rod 34 is in the state of being inserted into the telescopic frame 33, at the moment of unlocking, it will be pushed back to its original position under the elastic force of the lower spring 46, so that the compression rod 38 moves to the inclined surface of the lower right-angle block 41). Since the telescopic rod 34 can only slide laterally, under the pressure of the inclined surface of the lower right-angle block 41, it will push the compression rod 38 and the telescopic rod 34 into the telescopic frame 33, and gradually compress the lower spring 46. At this time, the U-shaped rod 36 will slide on the unlocking plate 42, and the unlocking plate 42 cannot continue to move upward with the lower right-angle block 41, so it will gradually compress the compression spring 43. Then, when the igniter 35 moves to the designated position, it can control the adjustment electric telescopic cylinder 40 to stop running, and then control the lateral electric telescopic cylinder 20 to start. The system resets, thereby resetting the U-shaped frame 19 and the upper plate 39, which in turn removes the unlocking plate 42 and the lower right-angle block 41 from the side of the telescopic rod 34. This releases the pressure on the U-shaped rod 36, and the upper spring 45 pushes the U-shaped rod 36 into the corresponding limiting groove 37. (If necessary, when the lower right-angle block 41 is removed, the unlocking plate 42 will be removed from below the U-shaped rod 36 first, so as to ensure that the U-shaped rod 36 can be inserted into the corresponding limiting groove 37 and avoid them being removed at the same time. The lower spring 46 then lowers the telescopic rod 34 and pushes it away.)
[0028] In summary, the above-described structure allows for automatic adjustment of the igniter 35 position based on the type of nozzle 3 being replaced, eliminating the need for manual adjustment by workers and further enhancing the device's convenience.
