[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figure 1 - Figure 5This invention provides a technical solution: a low-temperature SCR denitrification device for glass melting furnace flue gas, comprising a flue gas duct 100. Inside the flue gas duct 100, from left to right, are arranged a heater 101, a nitrogen injection grid 102, and a catalyst plate 103. A flow interception mechanism 200 is provided between the nitrogen injection grid 102 and the catalyst plate 103. The flow interception mechanism 200 can adjust the flow rate of the glass flue gas passing through the reaction, facilitating the full reaction of the flue gas with the catalyst plate 103 and improving the denitrification effect. Simultaneously, before the flue gas reacts with the catalyst plate 103, it allows the flue gas to be fully retained in the flue gas duct 100 for mixing and heating, further improving the reaction efficiency. The flow interception mechanism 200 includes a vertically fixed mounting column 201 inside the flue gas duct 100, located in the middle of the flue gas duct 100. Flow interception plates 202 are rotatably mounted on the front and rear surfaces of the mounting column 201. The outer end is arc-shaped, and the arc-shaped end can be made of soft silicone to facilitate the rotation of the flow interception plate 202 to contact the inner wall of the flue gas duct 100. An adsorption mesh plate 203 is provided on the left side of the flow interception plate 202. Quicklime material can be placed inside the adsorption mesh plate 203 to adsorb water vapor in the flue gas. The adsorption exothermic heat can further heat the flue gas, preventing the water vapor in the flue gas from being adsorbed by the catalyst plate 103 and affecting its catalytic activity. Multiple disturbance fans 204 are evenly arranged on the left side of the adsorption mesh plate 203. When the flue gas enters the flue gas duct 100, it impacts the disturbance fans 204. Multiple disturbance fans 204 rotate simultaneously to rotate the glass melting furnace flue gas and mix it fully with nitrogen, and make the gas temperature relatively uniform. A driving component 205 is provided between the mounting column 201 and the flow interception plate 202. The driving component 205 can be used to realize the simultaneous rotation of the two flow interception plates 202 to change the angle, thereby changing the distance between the outer end of the flow interception plate 202 and the inner wall of the flue gas duct 100.

[0035] The driving component 205 includes a rotating shaft 2051 that passes through the mounting column 201 and the flow interception plate 202. The rotating shaft 2051 is fixedly connected to the flow interception plate 202. Therefore, as the rotating shaft 2051 rotates, it can drive the flow interception plate 202 to rotate. The upper ends of the two rotating shafts 2051 pass through the flue gas duct 100 and are exposed on the outside. The upper ends of the two rotating shafts 2051 are respectively fitted with a driving wheel 2053 and a driven wheel 2052 that mesh with each other.

[0036] A distribution component 206 is provided on the right side of the mounting column 201. The distribution component 206 includes two mounting shafts 2061 that are rotatably mounted inside the flue gas duct 100. The two mounting shafts 2061 are provided with staggered spiral blades 2062. The two spiral blades 2062 rotate in opposite directions. The rotation of the two mounting shafts 2061 can make the two spiral blades 2062 rotate in opposite directions, so that the discharged flue gas can be distributed in a swirling motion within the multiple catalyst plates 103.

[0037] In this embodiment, preferably, a drive motor 2054 is installed on the upper surface of the flue gas duct 100 at the upper end of the rotating shaft 2051. The drive motor 2054 can drive the two rotating shafts 2051 to rotate synchronously. Material gates are opened on the upper and lower surfaces of the adsorption mesh plate 203, and the material gates pass through the flue gas duct 100 to facilitate the replacement of materials inside the adsorption mesh plate 203.

[0038] In this embodiment, preferably, the front end of the mounting shaft 2061 passes through the flue gas duct 100 and is exposed on the outside. The front ends of the two mounting shafts 2061 are fitted with pulleys 2064, and the two pulleys 2064 are fitted with transmission belts 2065. By combining the pulleys 2064 and the transmission belts 2065, the two mounting shafts 2061 can rotate synchronously. One of the mounting shafts 2061 is equipped with a drive motor 2063 at its front end to facilitate the rotation of the mounting shaft 2061.

[0039] In summary, when the flue gas from the glass melting furnace enters the flue gas duct 100, the two flow blocking mechanisms 200 block the flow of the flue gas duct 100, preventing the flue gas from directly flowing into the catalyst plate 103. At this time, the flue gas gradually passes through the heater 101 for heating and passes through the nitrogen injection grid 102. The injected nitrogen mixes with the flue gas, and the mixed gas impacts the disrupting fan 204. The disrupting fan 204 rotates under the impact, further mixing the mixed gas and causing it to stagnate in the flue gas duct 100, prolonging the time the flue gas spends in the furnace. The heating time in heater 101 is controlled by a disruptive fan 204, which further mixes the mixed gas and ensures thorough mixing of different gases. Simultaneously, the mixed gas acts on the adsorption mesh plate 203, where moisture in the mixed gas is adsorbed by the dry packing material and releases heat to further heat the gas. When flue gas circulation is needed, the drive motor 2054 is activated, rotating the rotating shaft 2051 and its drive wheel 2053, which in turn rotates the driven wheel 205. 2. The rotation drives the two rotating shafts 2051 and the flow interception plate 202 to rotate synchronously to the right. The distance between the outer end of the flow interception plate 202 and the inner wall of the flue gas duct 100 gradually increases, adjusting the flue gas flow rate. When the flue gas inflow is appropriate, the drive motor 2054 stops working, the flow interception plate 202 stops rotating, and the flue gas flows through the flow interception plate 202 toward the catalyst plate 103. At the same time, the drive motor 2063 works, and the two mounting shafts 2061 are connected by pulleys 2064 and transmission belt 2054. The 65-inch rotor rotates synchronously, with its two spiral blades 2062 rotating synchronously, causing the flue gas to flow back and forth and act on multiple catalyst plates 103. This facilitates the flue gas to fully react with the catalyst plates 103 for denitrification. The reacted flue gas then continues to be discharged outward along the flue gas duct 100. Throughout the process, the water vapor in the flue gas is prevented from being adsorbed by the catalyst plates 103, thus affecting its catalytic activity. At the same time, the flow rate of the flue gas entering the catalyst plates 103 is adjusted, and different gases are fully rotated and mixed to improve the denitrification effect of the flue gas.

[0040] Example 2

[0041] Reference Figure 6 - Figure 8 This is the second embodiment of the present invention.

[0042] In this embodiment, preferably, a vibration regeneration component 400 is provided between the catalyst plate 103 and the distribution component 206. The vibration regeneration component 400 continuously vibrates the catalyst plate 103 over a long period, causing the dust layer on the surface of the catalyst plate 103 to peel off and fall off. This prevents the dust layer from hindering the contact between the flue gas and the catalyst plate 103 for denitrification, thus regenerating the activity of the catalyst plate 103 and improving the denitrification treatment effect and convenience of the flue gas. The vibration regeneration component 400 includes an installation plate 405 located on the left side of the catalyst plate 103. A movable plate 404 is horizontally arranged on the inner side of the installation plate 405 between the two catalyst plates 103. The surface of the movable plate 404 has an arc-shaped groove 407. The surface of the catalyst plate 103 has a fixed arc block 408 that cooperates with the arc-shaped groove 407. As the movable plate 404 moves left and right, the multiple arc-shaped grooves 407 and the multiple fixed arc blocks 408 cooperate to continuously push the catalyst plate 103 to vibrate, facilitating the falling off of the dust layer on the surface of the catalyst plate 103.

[0043] In this embodiment, preferably, a sleeve gear 401 is sleeved at the rear end of the mounting shaft 2061 on the right side. A rotating gear 402 is meshed with the right side of the sleeve gear 401 and is rotatably connected to the inner wall of the flue gas duct 100. A support shaft is provided between the rotating gear 402 and the inner wall of the flue gas duct 100, and the support shaft does not affect the rotation of the rotating plate 4031. A connector 403 is provided between the rotating gear 402 and the mounting plate 405. The connector 403 can move with the rotating gear 402, thereby driving the moving plate 404 to move left and right.

[0044] In this embodiment, preferably, a rotating plate 4031 is rotatably provided on the front surface of the rotating gear 402, and a connecting plate 4032 is rotatably provided on the outer end of the rotating plate 4031. The two are rotatably connected to facilitate the rotation of the rotating plate 4031. A fixing lug 4033 is provided on the left side of the mounting plate 405, which is rotatably connected to the connecting plate 4032. A guide rail 406 is provided on the inner wall of the flue gas duct 100, which penetrates the mounting plate 405. The guide rail 406 can support and guide the mounting plate 405, and facilitate the left and right movement of the mounting plate 405.

[0045] In this embodiment, preferably, the left end of the movable plate 404 is provided with a sleeve plate 409 that is sleeved on the mounting long plate 405. A limiting bolt 410 is screwed onto the surface of the sleeve plate 409. The inner end of the limiting bolt 410 contacts the mounting long plate 405. The position of the sleeve plate 409 can be limited and fixed by the frictional resistance of the contact, which makes it easy to change the position of the sleeve plate 409 and to change the position of the movable plate 404 according to the distance between adjacent catalyst plates 103.

[0046] In summary, based on the distance between adjacent catalyst plates 103, the movable plate 404 can be positioned between the catalyst plates 103, and the arc groove 407 on the movable plate 404 cooperates with the fixed arc block 408. The drive motor 2063 drives the mounting shaft 2061 to rotate, and the two mounting shafts 2061 are connected by a pulley 2064 and a transmission belt 2065, so that the two mounting shafts 2061 rotate synchronously, driving the sleeve gear 401 and the rotating gear 402 meshing with it to rotate, driving the rotating plate 4031 to rotate. When the rotating plate 4031 rotates to the left end, it drives the connecting plate 4032 to rotate and move to the left, driving the mounting plate 405 to move to the left along the guide rail 406, driving the movable plate 404 to rotate. 04. Moving to the left, the arc-shaped groove 407 gradually disengages from the fixed arc block 408 that it is paired with. The fixed arc block 408, constrained by the arc shape, pushes the catalyst plate 103 to deform slightly inward. The fixed arc block 408 and the next arc-shaped groove 407 will return to their original positions. When the rotating plate 4031 rotates to the right, it drives the moving plate 404 to move to the right. Throughout the process, the moving plate 404 moves left and right repeatedly, allowing the arc-shaped groove 407 and the fixed arc block 408 to continuously cooperate, causing the catalyst plate 103 to vibrate slightly. This facilitates the vibration of dust off the surface of the catalyst plate 103 and allows it to fall into the feed hopper 104, ensuring that the flue gas can fully contact the catalyst plate 103 without affecting the denitrification effect of the flue gas.

[0047] Example 3

[0048] Reference Figure 9 This is the third embodiment of the present invention.

[0049] In this embodiment, preferably, a pneumatic component 300 is provided on the upper surface of the flue gas duct 100 above the catalyst plate 103. Using the pneumatic component 300, air can be blown downwards from above the catalyst plate 103 onto its surface, facilitating the rapid downward flow of dust from the catalyst plate 103 into the hopper 104. This improves the regeneration activity of the catalyst plate 103, reduces dust obstruction of the flue gas, and facilitates sufficient contact between the flue gas and the catalyst plate 103 surface for denitrification reaction. The pneumatic component 300 includes components located on adjacent catalyst plates 103. The gas blowing pipe 302 between the ends has multiple high-pressure nozzles 305 arranged along its length on its lower surface, so that the high-pressure gas ejected can impact the surface of the catalyst plate 103. The gas pump 301 that supplies gas to the gas blowing pipe 302 is arranged on the upper surface of the flue gas duct 100. An air supply pipe 303 is arranged on the left side of the air pump 301. A distribution pipe 304 that penetrates the flue gas duct 100 and is exposed on the outside is connected to the upper surface of the gas blowing pipe 302. The gas blowing pipe 302 is located inside the flue gas duct 100. The lower end of the air supply pipe 303 is connected to the distribution pipe 304.

[0050] In this embodiment, preferably, a hopper 104 located below the catalyst plate 103 is provided on the lower surface of the flue gas duct 100.

[0051] In summary, during use, the air pump 301 operates, drawing in outside air and sending it into the distribution pipe 304. The air pump 301's inlet pipe is equipped with a filter plate to prevent dust from entering the distribution pipe 304. The drawn-in air is then sent into the air supply pipe 303 and evenly distributed into the distribution pipe 304, before entering multiple blowing pipes 302. The air is then sprayed through high-pressure nozzles 305 and acts on the surface of the catalyst plate 103. The high-pressure gas blows the dust vibrating and peeling off the surface of the catalyst plate 103 downwards. Furthermore, the high-pressure gas reduces the adhesion between the dust and the catalyst plate 103, improving the dust removal efficiency, enhancing the regeneration activity of the catalyst plate 103, and increasing the denitrification effect of the catalyst plate 103 on the flue gas.

[0052] Example 4

[0053] This embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3.

[0054] In use, the flow interception mechanism 200 intercepts the flue gas duct 100, allowing the glass melting furnace flue gas to pass sequentially through the heater 101 and the nitrogen spray grid 102 for heating and mixing. The flow interception mechanism 200 also adsorbs and dries the water vapor in the flue gas, improving the mixing effect between the flue gas and nitrogen. By changing the flue gas intake, the appropriate amount of flue gas reacts fully with the catalyst plate 103 for denitrification. The vibration regeneration component 400 vibrates the catalyst plate 103 to remove the dust layer and regenerate the activity of the catalyst plate 103. In conjunction with the pneumatic component 300, the dust removal and feeding effect is improved.
