[0001] This utility model relates to the field of denitrification device technology, and in particular to a gas denitrification device. Background Technology

[0002] In industrial production and energy utilization, the emission of methane gas is a problem that cannot be ignored. If the nitrogen oxides contained in methane are emitted directly without treatment, they will not only cause serious air pollution, leading to environmental problems such as acid rain and photochemical smog, but also harm human health, such as irritating the respiratory tract and causing lung diseases. Therefore, denitrification treatment of methane is particularly important. In existing denitrification devices, impurities in the gas accumulate on the filter screen during gas filtration, causing blockage of the filter pores. This prevents the complete removal of impurities, affecting the normal operation and service life of the device, requiring frequent replacement of filter components, increasing operating costs and maintenance workload. Therefore, this utility model proposes a methane denitrification device. Utility Model Content

[0027] Example

[0028] like Figures 1 to 3 As shown, the present invention proposes a gas denitrification device, comprising: a denitrification tank 1 for denitrification, one end of which is connected to an air inlet pipe 2 to facilitate the introduction of gas into the interior of the denitrification tank 1, and the other end of which is connected to a connecting pipe 3 to facilitate the discharge of the denitrified gas; an addition pipe 4 extending through the upper end of the denitrification tank 1, one end of which is connected to a guide block 5, and the bottom surface of the guide block 5 is provided with multiple spray nozzles 6, which can uniformly spray the catalytic liquid, thereby achieving uniform contact with the gas for denitrification and improving the denitrification efficiency. The efficiency is improved; a gas guide box 7 is provided at one end of the connecting pipe 3, and the gas guide box 7 is connected to the connecting pipe 3 through it, so as to facilitate the gas flow into the interior of the gas guide box 7. An exhaust pipe 8 is connected to one end of the gas guide box 7, so as to facilitate the discharge of the filtered gas. A filter plate 9 for filtering gas is rotatably provided inside the gas guide box 7 through the shaft seat, which can filter impurities in the gas and prevent them from being discharged into the air and polluting the environment. A cleaning component 10 for cleaning the filter plate 9 is provided inside the gas guide box 7, which can ensure the filtration effect of the filter plate 9.

[0029] like Figure 2 and Figure 4 As shown, the cleaning assembly 10 includes a first rotating rod 101 rotatably mounted inside the air guide box 7 via a bearing seat, ensuring stable rotation of the first rotating rod 101. A fan blade 102 is fixedly sleeved on the outer wall of the first rotating rod 101, facilitating rotation of the first rotating rod 101 via the fan blade 102. The fan blade 102 is located at one end of the connecting pipe 3, facilitating blowing by airflow, thereby reducing energy consumption. First transmission wheels 103 are fixedly sleeved on both ends of the first rotating rod 101, facilitating simultaneous rotation of the first transmission wheels 103. Second rotating rods 104 are rotatably mounted on both sides of the inner wall of the air guide box 7 via bearing seats, facilitating stable rotation of the second rotating rods 104. A second transmission wheel 105 is fixedly sleeved on the outer wall of the second rotating rod 104. A transmission belt 106 is provided between the second transmission wheel 105 and the first transmission wheel 103. A cam 107 is fixedly sleeved on the outer wall of the second rotating rod 104, facilitating the second rotating rod 104 to drive the cam 107 to strike the filter plate 9.

[0030] Furthermore, the cleaning assembly 10 also includes a first mounting base 108 fixedly disposed on both sides of the inner wall of the air guide box 7. A telescopic rod 109 is rotatably mounted on the first mounting base 108. One end of the telescopic rod 109 is rotatably connected to a second mounting base 110. One end of the second mounting base 110 is fixedly connected to one side of the filter plate 9. A spring 111 is sleeved on the outer wall of the telescopic rod 109 to facilitate rapid rebound after the filter plate 9 is impacted.

[0031] Secondly, the bottom of the denitrification box 1 is designed with an arc shape, and a drain pipe 11 is installed through the bottom of the denitrification box 1 to facilitate the drainage of the bottom liquid.

[0032] Furthermore, an adsorption plate 12 is sealed and inserted on the upper surface of the air guide box 7, and a handle is fixedly installed on the upper end of the adsorption plate 12 for easy replacement. The adsorption plate 12 is an activated carbon plate, which can adsorb harmful substances in the gas before emission.

[0033] In addition, a slag discharge pipe 13 is installed through the bottom surface of the air guide box 7 to facilitate the discharge of impurities from the cleaning filter plate 9.

[0034] Finally, an impact block 14 is fixedly provided on one side of the filter plate 9, which enables the cam 107 to impact the impact block 14, thereby avoiding impact on the filter plate 9 and improving the service life of the filter plate 9.

[0035] The working principle of this embodiment is as follows: First, the gas containing methane enters the denitrification chamber 1 through the inlet pipe 2. The upper end of the denitrification chamber 1 is connected to the addition pipe 4. The addition pipe 4, through the guide block 5, allows multiple spray heads 6 to add the catalyst liquid required for denitrification into the denitrification chamber 1 for denitrification treatment. Since the bottom surface of the denitrification chamber 1 has an arc-shaped structure, the liquid after reaction is discharged through the drain pipe 11 at the bottom.

[0036] The denitrified gas enters the gas guide box 7 through the connecting pipe 3. The gas flow drives the fan blade 102 inside the gas guide box 7 to rotate. The fan blade 102 is fixed on the first rotating rod 101. The first transmission wheel 103 at both ends of the first rotating rod 101 drives the second transmission wheel 105 on the second rotating rod 104 to rotate through the transmission belt 106, thereby causing the cam 107 on the second rotating rod 104 to rotate accordingly.

[0037] As the cam 107 rotates, it impacts the filter plate 9. An impact block 14 is fixed on one side of the filter plate 9 to receive the impact. When the gas flows, the filter plate 9 filters the gas. The impact of the cam 107 can promptly shake off the impurities accumulated on the filter plate 9, preventing impurities from clogging the filter plate pores and ensuring continuous and sufficient filtration of the gas.

[0038] Telescopic rods 109 are rotatably mounted on the first mounting seats 108 on both sides of the inner wall of the air guide box 7. One end of the telescopic rod 109 is rotatably connected to the second mounting seat 110, which is connected to the filter plate 9. A spring 111 is sleeved on the outer wall of the telescopic rod 109. When the filter plate 9 is struck by the cam 107, the telescopic rod 109 and the spring 111 cooperate to make the filter plate 9 quickly spring back to its original position. This eliminates the need for frequent replacement of the filter components, reduces operating costs, minimizes maintenance workload, and extends the overall service life of the device.

[0039] An adsorption plate 12 is sealed and inserted into the upper surface of the gas guide box 7 to further adsorb impurities in the gas. A slag discharge pipe 13 is installed through the bottom surface of the gas guide box 7 to discharge solid impurities generated during the filtration and adsorption process. Finally, the fully treated gas is discharged from the device through the exhaust pipe 8.

[0040] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
