Description

Technical Field

[0001] This utility model belongs to the field of denitrification technology, specifically relating to a modular catalytic denitrification reaction device. Background Technology

[0002] Denitrification reaction refers to the process of removing nitrogen oxides from combustion flue gas, highlighting its importance in preventing environmental pollution. A search revealed that application number "CN202420485662.1" discloses a "modular catalytic denitrification reaction device," which describes a system consisting of an auxiliary rod, a moving block, an extension bar, straight scrapers, and a return spring. The rotation of the drive shaft drives the first convex plate to rotate. During this rotation, the first convex plate applies pressure to the second convex plate, transmitting the force to the moving block. The moving block then moves backward at one end of the auxiliary rod. The return spring, under pressure, compresses and deforms, causing multiple straight scrapers to move. The tops of the straight scrapers scrape against the bottom surface of the filter plate. During the scraping process, the loose hair accumulated at the bottom of the filter plate can be scraped away. This is achieved by using an auxiliary rod, a moving block, an extension bar, straight scrapers, and a return spring. The rotation of the drive shaft drives the first convex plate to rotate. During this rotation, the first convex plate applies pressure to the second convex plate, thus transmitting the force to the moving block. The moving block then moves backward at one end of the auxiliary rod. When the return spring is stressed, it compresses and deforms, which in turn moves multiple straight scrapers. The tops of the straight scrapers scrape against the bottom surface of the filter plate, scraping away the loose hair accumulated at the bottom of the filter plate. However, the above comparison document still has the following problems in actual use:

[0003] In actual use, it is impossible to mix ammonia and flue gas evenly, resulting in poor denitrification effect. Furthermore, the main components cannot be quickly disassembled during use, leading to maintenance difficulties.

[0004] Therefore, providing a device that can achieve uniform gas mixing and quickly disassemble the main components is of great practicality. Utility Model Content

[0007] The inner walls of the protective box are provided with several sliding guide rails on both sides;

[0008] The reaction assembly includes a connecting plate disposed inside two of the sliding guide rails. A mixing tank is disposed inside the connecting plate. A protective cover is disposed on the top of the mixing tank. A torque motor is disposed on the top of the protective cover. A rotating rod is disposed through the output shaft end of the torque motor and the outer wall of the rotating rod is disposed with several fan blades. Electric valves are sealed and connected to both sides of the top of the protective cover. A distribution ring is sealed and connected to the top of the two electric valves.

A connecting frame is sealed and connected to the top of the connecting frame. A catalyst plate is slidably connected inside the connecting frame. Both sides of the connecting frame are slidably connected to the interior of the other two sliding guide rails.

[0009] The modular quick-disassembly assembly includes two connecting blocks disposed on one side of the protective box. Each of the two connecting blocks has a hinge seat on one side. Each of the two hinge seats has a connecting rod hinged inside. Each of the two connecting rods has a fixing rod hinged in the middle. Each of the fixing rods has two damping springs on one side. Each of the two damping springs is fixedly connected to the protective box on one side. Each of the two connecting rods has a locking head on one end. The bottom of the connecting frame and the top of the connecting plate are provided with limit frames. Each of the two limit frames has a slot inside. The end of the other locking head is inserted into the slot.

[0010] In one embodiment of this utility model, both sides of the mixing tank are sealed and connected to connectors, one side of each connector is threaded with a connecting pipe, one side of each connecting pipe is sealed and connected to an external joint, and the outer walls of the two external joints are inserted and fixedly connected to the protective box.

[0011] In one embodiment of this utility model, the top of the protective box is sealed and connected to an air supply frame, and the top of the air supply frame is sealed and connected to an external pipe.

[0012] In one embodiment of this utility model, a protective door is hinged to one end of the protective box, a handle is provided at one end of the protective door, and a door lock is provided in the middle of one end of the protective door.

[0013] In one embodiment of this utility model, the protective box is made of titanium alloy.

[0014] In one embodiment of this utility model, the interior of the mixing tank is coated with an anti-corrosion coating, and a switch panel is provided on one side of the protective box.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1) The mixing tank allows users to easily connect the external connectors to the ammonia and flue gas pipelines, allowing ammonia and flue gas to enter the mixing tank. Users then activate the torque motor via a torque motor switch, causing the rotating rod to rotate, which in turn rotates the fan blades. This fan blade rotation promotes thorough mixing of the ammonia and flue gas. After mixing, users activate the electric valve switch, which sends the gas from the mixing tank through the distribution ring to the conveying head. The conveying head then sends the gas into a flexible hose, which in turn sends it to the catalytic plate in the connecting frame for catalysis before discharging it through the external connector. This achieves rapid mixing of ammonia and flue gas, improving work efficiency.

[0018] 2) The fixed rod facilitates easy disassembly, replacement, or maintenance of components. Users can separate the delivery head from the hose and the connector from the connecting pipe. After separation, pressing the fixed rod moves it to one side. This movement causes the damping rod spring to contract and store energy, which in turn moves the hinged connecting rod to one side. The connecting rod then slides the plug out of the slot via the hinge seat, thus limiting the position of the limit frame. After releasing the limit, users can pull the connecting plate and connecting frame out of the sliding guide rail for internal maintenance, achieving rapid disassembly and improving work efficiency.

[0026] Example

[0027] Please see Figure 1-4 A modular catalytic denitrification reactor includes a protective box 100, a reaction component 200, and a modular quick-disassembly component 300.

[0028] Please refer to the details. Figure 1 The inner walls of the protective box 100 are provided with several sliding guide rails 110.

[0029] Please see Figure 3 The reaction assembly 200 includes a connecting plate 210 disposed inside two sliding guide rails 110. A mixing tank 220 is disposed inside the connecting plate 210. A protective cover 230 is disposed on the top of the mixing tank 220. A torque motor 240 is disposed on the top of the protective cover 230. A rotating rod is disposed through the output shaft end of the torque motor 240 through the protective cover 230. Several fan blades 250 are disposed on the outer wall of the rotating rod. Electric valves 260 are sealed and connected to both sides of the top of the protective cover 230. A distribution ring 270 is sealed and connected to the top of the two electric valves 260. Several conveying heads 280 are sealed and connected to the top of the distribution ring 270. A hose 290 is threadedly connected to the top of the several conveying heads 280. A connecting frame 2910 is sealed and connected to the top of the several hoses 290. A catalyst plate 2920 is slidably connected inside the connecting frame 2910. Both sides of the connecting frame 2910 are slidably connected to the interior of the other two sliding guide rails 110.

[0030] In one specific embodiment, the provided mixing tank 220 allows users to easily connect the external connector 600 to the ammonia pipeline and the flue gas pipeline, respectively, allowing ammonia and flue gas to enter the mixing tank 220. The user then activates the torque motor 240 via a torque motor switch, causing the torque motor 240 to rotate the rotating rod, which in turn rotates the fan blade 250. The rotation of the fan blade 250 promotes thorough mixing of the ammonia and flue gas. After mixing, the user activates the electric valve 260 via an electric valve switch, causing the electric valve 260 to send the gas from the mixing tank 220 through the distribution ring 270 into the conveying head 280. The conveying head 280 then sends the gas into the flexible hose 290, which in turn sends the gas into the catalytic plate 2920 within the connecting frame 2910 for catalysis before discharging it through the external connector. This achieves rapid mixing of ammonia and flue gas, improving work efficiency.

[0031] Please see Figure 2-4 The modular quick-disassembly assembly 300 includes two connecting blocks 310 disposed on one side of the protective box 100. Each of the two connecting blocks 310 has a hinge seat 320 on one side. Each of the two hinge seats 320 has a connecting rod 330 hinged inside. Each of the two connecting rods 330 has a fixing rod 340 hinged in the middle. Each of the two fixing rods 340 has two damping rod springs 350 on one side. Each of the two damping rod springs 350 is fixedly connected to the protective box 100 on one side. Each of the two connecting rods 330 has a locking head 360 on one side of its end. Each of the connecting frame 2910 and the connecting plate 210 has a limit frame 370. Each of the two limit frames 370 has a slot inside. The end of the other locking head 360 is inserted into the slot.

[0032] In one specific embodiment, the fixed rod 340 facilitates the user's disassembly, replacement, or maintenance of components. The user separates the conveying head 280 from the hose 290 and the connector 400 from the connecting pipe 500. After separation, the user presses the fixed rod 340, causing it to move to one side. This movement causes the damping rod spring 350 to contract and store force. The movement of the fixed rod 340 then moves the hinged connecting rod 330 to one side. The connecting rod 330 then slides the plug out of the slot through the hinge seat 320, thereby limiting the position of the limiting frame 370. After releasing the limit, the user pulls the connecting plate 210 and the connecting frame 2910 out of the sliding guide rail 110 to perform internal maintenance, thus achieving rapid disassembly and improving work efficiency.

[0033] Please see Figure 2Both sides of the mixing tank 220 are sealed and connected to connectors 400. One side of each connector 400 is threaded with a connecting pipe 500. One side of each connecting pipe 500 is sealed and connected to an external connector 600. The outer walls of the two external connectors 600 are inserted and fixedly connected to the protective box 100.

[0034] In one specific embodiment, the connecting pipe 500 allows for easy separation of the connecting pipe 500 and the connector 400 during use, so that the mixing tank 220 can be stably pulled out along with the connecting plate 210 for easy maintenance.

[0035] Please see Figure 1 The top of the protective box 100 is sealed and connected to an air supply frame 700, and the top of the air supply frame 700 is sealed and connected to an external pipe.

[0036] In one specific embodiment, the protective box 100 is provided to protect the parts inside the protective box 100, thus preventing damage to the parts inside the protective box 100 due to shaking or bumping during use.

[0037] Please see Figure 1 The protective box 100 is hinged to a protective door 800 at one end, and a handle is provided at one end of the protective door 800. A door lock is provided in the middle of one end of the protective door 800.

[0038] In one specific embodiment, the provided door lock allows users to easily open the door with a key and open the protective door 800 with a handle, so as to inspect and maintain the parts inside the protective box 100, thereby improving work efficiency.

[0039] Please see Figure 1 The protective box 100 is made of titanium alloy.

[0040] In one specific embodiment, the titanium alloy provided allows the protective box 100 to be used more stably due to its robust and durable properties, thus preventing damage during use.

[0041] Please see Figure 3 The interior of the mixing tank 220 is coated with anti-corrosion paint, and a switch panel is provided on one side of the protective box 100.

[0042] In one specific embodiment, the presence of an anti-corrosion coating makes the mixing tank 220 less susceptible to corrosion during use, thereby increasing its service life.

[0043] Please see Figure 1-4The switch panel is equipped with a torque motor switch and an electric valve switch. The torque motor 240 is electrically connected to the torque motor switch, the electric valve 260 is electrically connected to the electric valve switch, and the switch panel is electrically connected to an external power supply.

[0044] In one specific embodiment, the provided switch panel facilitates the power supply control of electrical equipment, ensuring that the equipment is powered on when needed, thus avoiding the situation where power cannot be supplied when power is required.

[0045] In operation, the mixing tank 220 is provided for easy connection of the external connector 600 to the ammonia and flue gas pipelines, allowing ammonia and flue gas to enter the mixing tank 220. The user then activates the torque motor 240 via a torque motor switch, causing the rotating rod to rotate, which in turn rotates the fan blade 250. The fan blade 250 promotes thorough mixing of the ammonia and flue gas. After mixing, the user opens the electric valve 260 via an electric valve switch, which then sends the gas from the mixing tank 220 through the distribution ring 270 into the conveyor head 280. The conveyor head 280 then sends the gas into the hose 290, which in turn sends it into the catalytic plate 2920 within the connecting frame 2910 for catalytic oxidation before discharging it through the external connector. This rapid mixing of ammonia and flue gas improves operational efficiency. To improve efficiency, the fixed rod 340 allows users to easily disassemble, replace, or maintain components. Users separate the conveyor head 280 from the hose 290 and the connector 400 from the connecting pipe 500. After separation, the user presses the fixed rod 340, causing it to move to one side. This movement causes the damping spring 350 to contract and store force. The fixed rod 340 then moves the hinged connecting rod 330 to one side, allowing the plug to slide out of the slot via the hinge seat 320. Finally, it limits the position of the limiting frame 370. After releasing the limit, the user can pull the connecting plate 210 and the connecting frame 2910 out of the sliding guide rail 110 for internal maintenance, thus achieving rapid disassembly and improving work efficiency.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
