Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of combustion furnaces, and more specifically, to a catalytic combustion furnace. Background Art
[0002] In the existing technology, the catalytic bed plate is usually fixedly installed inside the furnace body. This design simplifies the furnace structure, but after long-term operation, the catalytic bed plate may need to be replaced or thoroughly cleaned due to dust accumulation, decreased catalyst activity or physical damage. Since the catalytic bed plate is fixed in the furnace body, these maintenance tasks become very difficult and time-consuming, which in turn leads to a significant increase in the cost of use. In addition, for occasions where the catalyst needs to be replaced frequently to adapt to different exhaust gas treatment requirements, the design of the fixed catalytic bed plate limits the flexibility and efficiency of the furnace body.
[0003] Secondly, traditional catalytic combustion furnaces lack an effective mechanism for quickly replacing catalytic bed plates. In actual operation, this means that the operation of the furnace must be suspended every time the catalyst is replaced or large-scale cleaning is performed, which not only affects production efficiency but may also result in additional operating costs. The lack of a rapid replacement process limits the adaptability of catalytic combustion furnaces in responding to rapidly changing industrial needs.
[0004] In the normal operation of a catalytic combustion furnace, the treated gases are usually discharged into the atmosphere through an exhaust duct. This exhaust process is critical to ensure that the exhaust gases are properly treated and eliminate potential environmental pollution. However, the design of existing catalytic combustion furnaces often cannot effectively provide a sealing mechanism when it is not necessary to exhaust the gases. This may become a problem in certain operating situations. For example, during furnace shutdown or maintenance, or when the demand for exhaust gas treatment is reduced, it may not be necessary to continuously exhaust the gases. In these cases, if the exhaust system cannot be effectively sealed, it may cause untreated exhaust gases to escape or outside air to enter the furnace, affecting the performance and safety of the furnace.

[0014] Compared with the prior art, the utility model provides a catalytic combustion furnace, which has the following beneficial effects:
[0015] 1. The filter assembly realizes efficient exhaust gas treatment and purification functions through the structural design of exhaust gas inlet, exhaust pipe and filter box. After the exhaust gas enters the furnace body, it is filtered by the activated carbon plate to effectively remove harmful substances and ensure the cleanliness and environmental friendliness of the exhaust gas.

[0017] 3. The introduction of the regulating component provides an effective gas flow rate and pressure regulating mechanism. Through the ingenious design of the exhaust pipe, the abutment block and the abutment rod, precise control of the exhaust gas flow rate is achieved.

The user can change the compression degree of the abutment spring by adjusting the rotating sleeve, thereby accurately controlling the gas emission speed and pressure to meet the needs under different operating conditions. The addition of this regulating function further improves the performance and environmental adaptability of the furnace body, ensuring the efficiency and environmental friendliness of the treatment process.

[0028] Through holes 12 are provided on the base 9 and the catalyst bed 10 , and the through holes 12 are adapted to the pull rod 11 , on which a fixing block 13 is fixedly mounted.
[0029] A pulling spring 14 is connected between the clamping seat 9 and the fixing block 13 , and a pulling plate 15 is provided on one side of the pulling rod 11 .
[0030] A pulling handle 16 is installed on one side of the pulling plate 15 .
[0031] In this embodiment, during the use of this device, the exhaust gas is manually introduced into the furnace body 1 from the exhaust gas inlet 2. After the exhaust gas enters the furnace body 1, the catalytic bed 10 on the inner side of the holder 9 is used to complete the exhaust gas treatment process. After the exhaust gas is treated, it is finally discharged along the exhaust pipe 6, so that it enters the activated carbon plate 24 in the filter box 7, so that the gas is filtered and finally discharged to the outside of the furnace body 1. After the catalytic bed 10 has been used for a period of time, it is necessary to replace the catalytic bed 10 in time. At this time, the pull handle 16 is manually moved, thereby driving the pull plate 15 on one side of the pull handle 16 to move. This causes the pulling rod 11 to slide and move. At this time, with the cooperation of the fixing block 13, the pulling spring 14 between the fixing block 13 and the holder 9 is squeezed, so that the pulling rod 11 moves out of the through hole 12 of the catalyst bed 10 plate. At this time, the catalyst bed 10 plate is manually removed, and then a new catalyst bed 10 plate is inserted into the holder 9. After the through hole 12 of the holder 9 is aligned with the pulling rod 11, the pulling handle 16 is released, so that under the action of the pulling spring 14, the pulling plate 15 and the pulling rod 11 are driven to slide along the through hole 12, thereby inserting the pulling rod 11 into the holder 9, completing the fixing process of the catalyst bed 10 plate.
[0032] See also Figure 4-5 As a catalytic combustion furnace implementation method of the adjustment component: an adjustment component is arranged on one side of the outlet pipe 6, and the adjustment component includes an exhaust pipe 17, a stop block 18 and a stop rod 19. The exhaust pipe 17 is connected to one side of the outlet pipe 6, the stop block 18 is installed on the exhaust pipe 17, and the stop rod 19 is connected to the stop block 18.
[0033] A resisting spring 20 is sleeved on the outer side of the resisting rod 19 , one end of the resisting spring 20 is connected to the resisting block 18 , and a resisting sleeve 21 is slidably connected to the outer side of the resisting rod 19 .
[0034] The abutting sleeve 21 is connected with a sliding block 22 , and the sliding block 22 is slidably connected to the inner side of the exhaust pipe 17 .
[0035] A rotating sleeve 23 is rotatably connected to one end of the exhaust pipe 17 , and the rotating sleeve 23 abuts against the sliding block 22 . An activated carbon plate 24 is disposed inside the filter box 7 .
[0036] More specifically, when the filtered gas is discharged along the outlet pipe 6, it flows into the filter box 7 along the outlet pipe 6, and is filtered by the activated carbon plate 24 in the filter box 7, so that it flows into the exhaust pipe 17. During the flow of the gas, the gas pushes the abutment block 18 in the exhaust pipe 17. During the pushing process, the abutment rod 19 slides along the abutment sleeve 21, and the abutment spring 20 on the abutment rod 19 is compressed, so that the abutment block 18 leaves one side of the exhaust pipe 17, so that the gas is discharged along the other side of the exhaust pipe 17. When the stiffness coefficient of the abutment spring 20 needs to be adjusted, the abutment block 18 is compressed. When adjusting, the rotating sleeve 23 on the exhaust pipe 17 is manually rotated so that the inner side of the rotating sleeve 23 rotates and moves along the exhaust pipe 17, thereby driving the sliding block 22 to slide and move inside the exhaust pipe 17, driving the abutting sleeve 21 to move, and the abutting rod 19 is retracted into the abutting sleeve 21, thereby compressing the abutting spring 20. When it is necessary to restore the abutting spring 20 to its initial position, the rotating sleeve 23 is manually rotated in the reverse direction so that the rotating sleeve 23 moves in the reverse direction along the exhaust pipe 17, thereby releasing the compression process of the abutting spring 20 and restoring it to its initial tensioned state.
[0037] In summary, when the overall equipment is in use or running: during the use of this device, the exhaust gas is manually introduced into the furnace body 1 from the exhaust gas inlet 2. After the exhaust gas enters the furnace body 1, the catalytic bed 10 on the inner side of the holder 9 is used to complete the exhaust gas treatment process. After the exhaust gas is treated, it is finally discharged along the exhaust pipe 6, so that it enters the activated carbon plate 24 in the filter box 7, so that the gas is filtered and finally discharged to the outside of the furnace body 1. After the catalytic bed 10 has been used for a period of time, it is necessary to replace the catalytic bed 10 in time. At this time, the pull handle 16 is manually moved, so that the pull plate 15 on one side of the pull handle 16 is driven to move. The pulling rod 11 is driven to slide and move. At this time, with the cooperation of the fixing block 13, the pulling spring 14 between the fixing block 13 and the holder 9 is squeezed, so that the pulling rod 11 is moved out of the through hole 12 of the catalyst bed 10. At this time, the catalyst bed 10 is manually removed, and then a new catalyst bed 10 is inserted into the holder 9. After the through hole 12 of the holder 9 is aligned with the pulling rod 11, the pulling handle 16 is released to drive the pulling plate 15 and the pulling rod 11 to slide along the through hole 12 under the action of the pulling spring 14, thereby inserting the pulling rod 11 into the holder 9, so as to complete the fixing process of the catalyst bed 10.
[0038] When the filtered gas is discharged along the outlet pipe 6, it flows into the filter box 7 along the outlet pipe 6, and is filtered by the activated carbon plate 24 in the filter box 7, so that it flows into the exhaust pipe 17. During the flow of the gas, the gas pushes the abutment block 18 in the exhaust pipe 17. During the pushing process, the abutment rod 19 slides along the abutment sleeve 21, and the abutment spring 20 on the abutment rod 19 is compressed, so that the abutment block 18 leaves one side of the exhaust pipe 17, so that the gas is discharged along the other side of the exhaust pipe 17. When the stiffness coefficient of the abutment spring 20 needs to be adjusted, During the operation, the rotating sleeve 23 on the exhaust pipe 17 is manually rotated so that the inner side of the rotating sleeve 23 rotates and moves along the exhaust pipe 17, thereby driving the sliding block 22 to slide and move inside the exhaust pipe 17, driving the abutting sleeve 21 to move, and causing the abutting rod 19 to be retracted into the abutting sleeve 21, thereby compressing the abutting spring 20. When the abutting spring 20 needs to be restored to its initial position, the rotating sleeve 23 is manually rotated in the reverse direction so that the rotating sleeve 23 moves in the reverse direction along the exhaust pipe 17, thereby releasing the compression of the abutting spring 20 and restoring it to its initial tensioned state.
[0039] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
