[0002] A regenerative thermal oxidizer is an energy-saving and environmentally friendly device that is highly efficient and stable in treating organic waste gas. Its basic principle is to oxidize the waste gas at high temperatures to produce carbon dioxide and water, thereby purifying the waste gas and recovering the heat released during decomposition, achieving the dual goals of environmental protection and energy conservation.
[0003] During use, the exhaust gas moves quickly and travels a short distance in the oxidation furnace, which can easily lead to poor purification of the exhaust gas. In addition, it is inconvenient to filter impurities in the exhaust gas during combustion, thus reducing the effectiveness of exhaust gas treatment. Utility Model Content

[0012] Compared with the prior art, this utility model provides a rotary regenerative thermal oxidation furnace, which has the following beneficial effects:
[0013] 1. In this rotary regenerative thermal oxidizer, the exhaust gas in the lower combustion chamber moves in a serpentine pattern as it passes through the upper and lower air inlets, thereby increasing the travel distance of the exhaust gas within the lower combustion chamber. The exhaust gas is then combusted by the lower flame jet. After combustion, the exhaust gas passes through the filter screen on the left side and enters the upper combustion chamber. The serpentine flow of the exhaust gas within the upper combustion chamber further increases its travel distance. The upper flame jet also continuously combusts the exhaust gas, ensuring thorough combustion and improving the treatment efficiency.
[0014] 2. In this rotary regenerative thermal oxidizer, as the exhaust gas flows in a serpentine pattern inside the upper and lower combustion chambers, the exhaust gas is continuously filtered through the filters at the upper and lower air inlets to improve the purity of the exhaust gas after combustion, ensuring that the exhaust gas can be fully combusted as it moves from bottom to top.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Please see Figure 1-5 This utility model provides a rotary regenerative thermal oxidation furnace, including a furnace body 1, an air inlet pipe 2 fixed on the lower left side of the furnace body 1, a U-shaped conduit 3 fixed on the upper left side of the furnace body 1, burners 4 fixed on both sides of the furnace body 1, a heat storage pipe 5 fixed on the upper right side of the furnace body 1, an air inlet chamber 6 opened at the bottom of the furnace body 1, a heat storage chamber 7 opened at the top of the furnace body 1, a left horizontal plate 8 fixed on the inner wall of the left side of the furnace body 1, a right horizontal plate 9 fixed on the inner wall of the right side of the furnace body 1, an upper partition 10 fixed on the bottom surface of the left horizontal plate 8 and the right horizontal plate 9, and a lower partition 11 fixed on the upper surface of the left horizontal plate 8 and the right horizontal plate 9.
[0023] The gap between the upper partition 10 and the left and right horizontal plates 8 and 9 forms the upper combustion chamber 12; the gap between the lower partition 11 and the left and right horizontal plates 8 and 9 forms the lower combustion chamber 13; the gap between the upper partition 10 and the lower left or right horizontal plate 8 forms the upper air guide port 14; the gap between the lower partition 11 and the upper left or right horizontal plate 8 forms the lower air guide port 15; a material conveying pipe 16 is fixed inside the left and right horizontal plates 8 and 9; an upper flame gun 17 is fixed to the top surface inside the upper combustion chamber 12; a lower flame gun 18 is fixed to the bottom surface inside the lower combustion chamber 13; and the left and right horizontal plates 8 and 9 are connected to the furnace... The gap between the inner walls of body 1 forms a side air guide port 19. The upper air guide port 14 and the lower air guide port 15 are provided with vertical slots 20. A vertical frame 21 is movably engaged inside the vertical slots 20. A horizontal slot 22 is provided inside the side air guide port 19. A horizontal frame 23 is movably engaged inside the horizontal slots 22. A filter screen 24 is fixed inside the vertical frame 21 and the horizontal frame 23. The exhaust gas is transported to the intake chamber 6 through the intake pipe 2. As the exhaust gas increases, it begins to move to the right side air guide port 19 and enters the upper combustion chamber 12 and the lower combustion chamber 13 so that the exhaust gas can be burned and treated in the future.
[0024] Furthermore, the vertical frame 21 is movably engaged with the upper partition 10 and the lower partition 11 via the vertical slot 20, and the horizontal frame 23 is movably engaged with the left horizontal plate 8 and the right horizontal plate 9 via the horizontal slot 22, which facilitates the quick replacement of the internal filter screen 24 through the vertical frame 21 and the horizontal frame 23.
[0025] Furthermore, the upper air guide port 14 is located below the upper baffle 10, and the lower air guide port 15 is located above the lower baffle 11. The upper air guide port 14 and the lower air guide port 15 are staggered, so that the exhaust gas can move in a snake-like shape when it flows inside the upper combustion chamber 12 and the lower combustion chamber 13.
[0026] Furthermore, the upper combustion chamber 12 and the lower combustion chamber 13 are staggered vertically, and the upper air guide port 14 and the lower air guide port 15 are staggered horizontally, so that the exhaust gas can move in a snake shape through the upper air guide port 14 and the lower air guide port 15, and the exhaust gas can be combusted through the upper combustion chamber 12 and the lower combustion chamber 13.
[0027] Furthermore, the left horizontal plate 8 and the right horizontal plate 9 are arranged alternately, and the burner 4 is connected to the upper flame gun 17 and the lower flame gun 18 through the feed pipe 16, so that the gas required for combustion can be delivered to the upper flame gun 17 and the lower flame gun 18 through the feed pipe 16.
[0028] Furthermore, the heat storage chamber 7 is connected to the furnace body 1 through the U-shaped conduit 3, which facilitates the filtered waste gas to enter the heat storage chamber 7 through the U-shaped conduit 3 for storage, and the heat generated by the waste gas can be discharged and reused through the heat storage pipe 5.
[0029] During use, exhaust gas is delivered to the intake chamber 6 through the intake pipe 2, as per the instruction manual. Figure 3 As shown, as the exhaust gas increases, it begins to move towards the right-side air guide port 19, and then enters the lower combustion chamber 13. The exhaust gas in the lower combustion chamber 13 moves in a serpentine pattern as it passes through the upper air guide port 14 and the lower air guide port 15, thus increasing the travel distance of the exhaust gas within the lower combustion chamber 13. While the exhaust gas flows to the left in a serpentine pattern within the lower combustion chamber 13, the burner 4 delivers the necessary combustion gas to the lower flame gun 18 via the feed pipe 16, thereby burning the exhaust gas inside the lower combustion chamber 13. The exhaust gas after combustion in the lower combustion chamber 13 is filtered by the filter screen 24 on the left and then enters the upper combustion chamber 12. As can be seen from the above, the serpentine flow of the exhaust gas to the right within the upper combustion chamber 12 increases the travel distance of the exhaust gas within the lower combustion chamber 13. The flow path inside the upper combustion chamber 12 allows for continuous combustion of the exhaust gas via the upper burner 17. This continuous combustion ensures thorough combustion and improves the treatment effect of the exhaust gas. Furthermore, as the exhaust gas flows in a serpentine pattern within the upper and lower combustion chambers 12 and 13, it is continuously filtered by the filters 24 at the upper and lower air inlets 14 and 15, improving the purity of the combustion process. This ensures complete combustion as the exhaust gas moves upwards. The filtered exhaust gas then enters the heat storage chamber 7 via the U-shaped conduit 3 for storage, and the heat generated by the exhaust gas is discharged and reused via the heat storage pipe 5.
