[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] Example 1:

[0032] An environmentally friendly catalytic combustion system, such as Figures 1-6 As shown, it includes a catalytic combustion furnace, a heat exchange section 1, and a heating section 4. Two partitions 5 are installed on the inner side of the heating section 4, and a catalytic section 6 is formed between the two partitions 5. A catalytic mechanism 7 is provided on the inner side of the catalytic section 6.

[0033] The catalytic mechanism 7 includes several mounting frames 701. One end of the mounting frame 701 near the back of the catalytic combustion furnace is rotatably connected to the back plate of the catalytic combustion furnace via a rotating rod 706. Several catalyst blocks 703 are slidably mounted on the inner side of the mounting frame 701. A slot 702 for contacting the waste gas with the catalyst blocks 703 is opened on the outer side of the mounting frame 701. Two baffles 5 installed on the inner side of the heating section 4 form the catalytic section 6, making the catalytic reaction area more defined and concentrated, which is conducive to improving the efficiency of the catalytic reaction. At the same time, the catalytic mechanism 7 inside the catalytic section 6 includes several mounting frames 701. These mounting frames 701 are rotatably connected to the back plate of the catalytic combustion furnace via a rotating rod 706, which allows the mounting frames 701 to be flexibly adjusted as needed, facilitating the replacement and maintenance of the catalyst blocks 703. In addition, the several catalyst blocks 703 slidably mounted on the inner side of the mounting frame 701 allow the waste gas to fully contact the catalyst blocks 703, further improving the effect of the catalytic reaction, thereby effectively reducing the emission of harmful substances in the waste gas.

[0034] See Figure 2 , Figure 3 , Figure 4 A gap is formed between adjacent mounting frames 701 to allow for rotation of the mounting frames 701. Several mounting frames 701 are arranged in a rectangular array. The gap between adjacent mounting frames 701 provides room for rotation of the mounting frames 701, allowing them to rotate flexibly and facilitating the flipping and maintenance of the catalyst blocks 703. At the same time, the rectangular array arrangement of several mounting frames 701 not only makes the overall structure of the catalytic mechanism 7 more compact and stable, but also facilitates the uniform distribution of exhaust gas in the catalytic section 6, ensuring that each catalyst block 703 can fully contact the exhaust gas, thereby improving the uniformity and efficiency of the catalytic reaction.

[0035] See Figure 2 , Figure 3 , Figure 4The inner side of the mounting frame 701 is formed with a mounting cavity, and the catalyst block 703 is matched with the mounting cavity to slide, and the mounting cavity provides a stable mounting position for the catalyst block 703, so that the catalyst block 703 can be firmly mounted in the mounting frame 701 and is not easy to fall off or shift. At the same time, the catalyst block 703 is matched with the mounting cavity to slide, so that the catalyst block 703 can flexibly slide in the mounting frame 701, facilitating the replacement and adjustment of the catalyst block 703. Not only the installation and maintenance efficiency of the catalyst block 703 is improved, but also the full contact of the catalyst block 703 with the exhaust gas is ensured, and the effect of the catalytic reaction is improved.

[0036] Embodiment two:

[0037] Referring to Figure 2 , Figure 3 , Figure 4 , Figure 6 , a baffle 704 is mounted on a row of mounting frames 701 to block the gap between adjacent mounting frames 701 and limit the flow path of the exhaust gas. The baffle 704 can effectively block the gap between adjacent mounting frames 701 and limit the flow path of the exhaust gas, so that the exhaust gas can more concentratedly pass through the slot 702 and contact the catalyst block 703, improving the efficiency of the catalytic reaction. At the same time, the baffle 704 can also guide the flow direction of the exhaust gas, so that the exhaust gas can be more evenly distributed on each catalyst block 703, improving the uniformity and stability of the catalytic reaction.

[0038] Referring to Figure 2 , Figure 3 , Figure 4 , Figure 6 , the baffle 704 is limited and supported by the limiting frame 705 arranged on the inner wall of the catalytic combustion furnace and the inner side of the partition plate 5. The baffle 704 is detachably connected, so that the baffle 704 can be firmly mounted in the catalytic part 6 and is not easy to fall off or shift, ensuring the stability of the blocking and guiding effect of the baffle 704. At the same time, the baffle 704 is detachably connected, so that the baffle 704 can be conveniently disassembled and replaced when needed, facilitating the overhaul and maintenance operation of the catalytic part 6. Not only the maintainability and flexibility of the device are improved, but also the service life of the baffle 704 is prolonged and the operation cost of the system is reduced.

[0039] Referring to Figure 1 , Figure 2 , Figure 4 , Figure 5The heat exchange part 1 is provided with an air inlet 2 and an air outlet 3 on both sides, and the front side of the catalytic part 6 is rotatably provided with an access door 8, so that the exhaust gas can smoothly enter and leave the system, improving the ventilation efficiency and exhaust gas treatment capacity of the device, and also helping to reduce the accumulation and stagnation of exhaust gas in the heat exchange part 1, reducing the corrosion and wear of the heat exchange part 1 by exhaust gas, and prolonging the service life of the heat exchange part 1. In addition, the access door 8 rotatably arranged on the front side of the catalytic part 6 provides convenient conditions for the maintenance and maintenance of the system. When the catalyst block 703 needs to be repaired or replaced, the access door 8 can be opened for operation without disassembling the entire system device, greatly improving the efficiency of repair and maintenance.

[0040] Referring to Figure 4 The inner side of the heating part 4 is provided with a plurality of electric heaters, which can uniformly heat the exhaust gas entering the catalytic part 6 to a temperature suitable for catalytic reaction, improving the efficiency of catalytic reaction. At the same time, the use of electric heaters can also reduce the dependence on traditional heating methods, reduce the energy consumption and operating cost of the system, and in addition, the heating speed of the electric heater is fast, which can quickly heat the exhaust gas to the required temperature, shorten the residence time of the exhaust gas in the system, and improve the processing capacity of the system.

[0041] The implementation principle of the embodiment is that the exhaust gas enters the heating part 4 through the air inlet 2 of the heat exchange part 1, the electric heaters arranged on the inner side of the heating part 4 heat the exhaust gas to a temperature suitable for catalytic reaction, and the heated exhaust gas enters the catalytic part 6 formed by the two partitions 5. In the catalytic part 6, the exhaust gas contacts the catalyst block 703 slidingly installed on the inner side of the mounting frame 701 through the slot 702 on the outer side of the mounting frame 701, and a catalytic reaction occurs, oxidizing carbon monoxide in the exhaust gas into harmless carbon dioxide. According to the attenuation of the catalyst block 703, when there is a certain difference between the upper and lower parts of the same catalyst block 703, first, the baffle 704 is removed by sliding, then the mounting frame 701 is rotated by rotating the rod 706 until the several catalyst blocks 703 installed on the inner side of the mounting frame 701 are turned upside down, and then the baffle 704 is reinstalled on the same row of mounting frames 701 through the limiting frame 705. According to the above operation, by turning over the catalyst block 703, the degree of difference in the upper and lower parts of the same catalyst block 703 can be reduced to improve the use effect of the catalyst block 703 and reduce the cost of catalytic combustion.
