Description

Technical Field

[0001] The invention relates to the technical field of flue gas denitrification, and in particular to an automatic zoned injection device and method for efficiently and accurately metering ammonia water. Background Art

[0002] As the country pays more and more attention to environmental protection, the waste gas treatment standards of industrial emission sources such as coal-fired power plants and chemical plants are constantly improving. As a commonly used desulfurization and denitrification agent, the precise control of the injection amount of ammonia water is of great significance for improving the efficiency of waste gas treatment, reducing ammonia escape, and reducing operating costs. However, traditional ammonia water injection systems often adopt fixed injection strategies and cannot be flexibly adjusted according to the real-time concentration and distribution of pollutants in the flue gas, resulting in low ammonia water utilization efficiency and serious ammonia escape. In order to overcome these limitations, an automated partitioned injection device for ammonia water came into being. The device integrates advanced sensor technology, automated control systems and precise metering devices to achieve real-time and precise control of the ammonia water injection amount.

[0003] For example, the patent application with the prior art announcement number CN213668690U provides an efficient and accurate ammonia metering injection device, including an ammonia storage tank, which is connected to a spray gun arranged in a kiln through a pipeline, a metering pump is arranged on the pipeline, and a smoke component detector is also arranged in the kiln. The metering pump and the smoke component detector are both controlled by a PLC control cabinet. A heat insulation board is arranged on the outside of the kiln, and a thermoelectric plate is arranged on the heat insulation board; the thermoelectric plate includes a hot end and a cold end arranged relatively, the hot end of the thermoelectric plate penetrates the heat insulation board and the kiln and extends into the kiln, and the cold end of the thermoelectric plate is exposed outside the heat insulation board; an electric heating wire is arranged in the spray gun, and the electric heating wire is electrically connected to the thermoelectric plate. This application can automatically adjust the injection amount of ammonia water, realizes the fully automatic control of the injection amount of ammonia water, helps to measure and control the injection amount of ammonia water efficiently and accurately, and does not require personnel on duty. In addition, by setting the thermoelectric plate and the heat dissipation wire, it helps to gasify the ammonia water when it is injected.

[0004] The above-mentioned prior art has demonstrated excellent performance in the field of denitrification by virtue of its ability to automatically adjust the amount of ammonia injection, and has effectively ensured a high level of denitrification effect. However, in the actual application process, a key problem that needs to be solved has gradually emerged: ammonia often inevitably carries a certain amount of impurities in the feeding stage, and these impurities pose a severe challenge to the subsequent atomization treatment. Specifically, the presence of impurities may not only directly block the tiny channels of the atomizing nozzle, causing the instability or even complete interruption of the injection pressure, seriously affecting the continuity and stability of the injection; more importantly, they will also cause a series of adverse consequences during the atomization process. Impurities will disrupt the uniform distribution of ammonia droplets, making the atomized droplets of different sizes and shapes, greatly reducing the fineness and uniformity of the atomization. This uneven atomization effect directly weakens the effective contact area and contact time between ammonia droplets and pollutants in the exhaust gas, thereby reducing the chemical reaction efficiency between the two, and has a negative impact on the denitrification effect that cannot be ignored. To this end, the present application proposes an automated partition injection device and method for efficient and accurate metering of ammonia. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The blade assembly is driven by a driving motor to rotate, the incoming gas is compressed, and the compressed gas is sent to the atomizing pipe through the compressed air pipe to atomize the ammonia water. This design improves the atomization efficiency of the ammonia water and helps to spray the ammonia water more evenly.

Diverter pipe and flow meter: The partition of the ammonia water is controlled by the valve. The flow meter can accurately measure the ammonia flow of each partition to achieve accurate metering. The cylindrical bracket and its filter: The filter can effectively block impurities and particles in the ammonia water and improve the purity of the ammonia water. The cleaning strip and the collection assembly are tightly fitted with the filter. The impurities are sucked into the return sump through the channel formed by the suction hole and the hollow spring rod, which effectively prevents the filter from being blocked and improves the filtration efficiency. Roller, lifting sheet and turbine: The rotation of the roller drives the turbine to rotate continuously through the roller, generating negative pressure, which promotes the suction and discharge of impurities and a small amount of ammonia water. At the same time, the lifting plate lifts the ammonia water under the cylindrical bracket and returns it to the inside of the cylindrical bracket through the filter below, realizing the recycling of ammonia water. The multifunctional design of the driving motor and the connecting rod: the connecting rod not only drives the blade assembly to compress the gas, but also drives the flow delivery blade to accelerate the flow of ammonia water, and through the combined design of the roller, the resistance rod and the movable plate, a small misalignment of the cylindrical bracket is achieved to ensure that the cleaning strip can fully clean the filter.

[0017] 2. The rotation of the inner guide tube drives the sleeve ring to rotate together, and then the guide bead is displaced through the swing guide groove, so that the pull ring drives the rotating tube to rotate and swing. This design enables the nozzle to continuously change the injection angle, thereby expanding the injection range of ammonia and accelerating its contact efficiency with pollutants in the exhaust gas. The nozzles are not only numerous, but also divergently arranged, which can achieve comprehensive angle injection under the action of the synergistic component, further improve the injection range, and ensure that ammonia can fully contact the exhaust gas.

This design not only realizes the function of the synergistic component, but also ensures the efficient flow of ammonia between the inner guide tube and the injection tube. The flow rate of ammonia is accelerated by the tight hole, so that more ammonia can enter the injection area, which improves the utilization rate of ammonia. The inner guide tube and the tight hole: the tight hole in the inner guide tube not only accelerates the flow rate of ammonia, but also allows the ammonia to be fully dispersed and homogenized before entering the injection area. This design helps optimize the injection effect, allowing ammonia to be more evenly distributed in the exhaust gas, improving the desulfurization and denitrification efficiency, and the synergistic effect of the filter chamber and the diverter pipe: the filter chamber ensures the purity of the ammonia, and the diverter pipe achieves accurate metering of the ammonia. The injection pipe and its enhancement components further inject pure and accurately metered ammonia into the exhaust gas in the best way, achieving comprehensive optimization and control from the source to the injection terminal.

Under the continuous disturbance of the moving blades, the gas entering the filter chamber 200 through the air inlet valve 206 is continuously increased and finally transported to the inside of the atomizing pipe 103 through the compressed air pipe 204 to atomize the ammonia water, wherein the pressure gauge 205 can detect the pressure value of the compressed gas.

[0023] Furthermore, in order to optimize the purity of the ammonia water, a barrel-shaped cylindrical support 300 is further included, which is arranged inside the filter chamber 200 for filtering the ammonia water, and a cleaning bar 303 is arranged inside the filter chamber 200 for cleaning impurities, and a collecting component for scraping impurities from the cleaning bar 303 is arranged inside the filter chamber 200 for collection. By setting the collecting component, the impurities filtered can be effectively collected, thereby improving the filtering efficiency of the barrel-shaped cylindrical support 300; The bottom of the connecting rod 202 penetrates the interior of the cylindrical bracket 300 and is fixedly connected with a plurality of flow delivery blades 312 for accelerating the flow of ammonia water. The flow delivery blades 312 can accelerate the flow rate of ammonia water, thereby improving the discharge efficiency of ammonia water. The outer surface and the bottom of the cylindrical bracket 300 are both constructed with a filter screen 301, which can filter ammonia water and block impurities and particles carried inside it. The outer surface of the cylindrical bracket 300 is evenly fixedly connected with a plurality of blocking bars 302. The collecting component includes a reflux trough 305 opened in the filter chamber 200, and the interior of the filter chamber 200 is fixedly connected with a hollow spring rod 304 fixedly connected with a spring end and a cleaning bar 303, and the hollow The interior of the spring rod 304 is interconnected with the return sewage trough 305, and a plurality of suction holes 311 connected to the interior of the cleaning strip 303 are provided on one side of the cleaning strip 303. The suction holes 311 form a channel through the cleaning strip 303 and the hollow spring rod 304 and the return sewage trough 305, wherein the blocking strip 302 can fit with the interior of the filter chamber 200 to prevent ammonia water from passing through the filter screen 301, and the cleaning strip 303 can fit with the filter screen 301 to clean the debris on its outer surface, and the suction holes 311 arranged inside the cleaning strip 303 can form a negative pressure inside it, so that the scraped impurities are sucked into the interior of the return sewage trough 305 through the suction holes 311 and transported to the bottom of the cylindrical bracket 300 for storage.

[0024] Furthermore, a roller 309 is fixedly connected to the bottom of the connecting rod 202, a transmission rod 306 is rotatably connected to the inside of the return trough 305, and a turbine 307 is fixedly connected to the outer surface of the transmission rod 306, and the turbine 307 is used to extract air from the return trough 305, one end of the transmission rod 306 is fixedly connected to a roller 308 adapted to the roller 309, a plurality of lifting pieces 310 with inclined surfaces are evenly fixedly connected to the top of the roller 309, and the lifting pieces 310 are used to push the ammonia water to rise, the outer surface of the connecting rod 202 is fixedly connected to the contact rod 314, and the bottom of the cylindrical bracket 300 is rotatably connected to a roller 308 adapted to the roller 309, and the lifting pieces 310 are used to push the ammonia water to rise, The movable sheet 313 is abutted against by the abutment rod 314, and the connecting sleeve of the movable sheet 313 is provided with a torsion spring for its own reset. The roller 309 will continue to rotate under the drive of the connecting rod 202, thereby driving the roller 308 to rotate, so that the turbine 307 continues to rotate, and then continuously extracts the gas in the return flow tank 305, so that negative pressure is generated inside the cleaning strip 303, and then impurities can be adsorbed into the return flow tank 305. At the same time, the rotation of the roller 309 will cause the lifting sheet 310 to rotate and push the ammonia water entering the bottom of the cylindrical bracket 300 to flow back to the inside of the cylindrical bracket 300 through the filter screen 301 at its bottom for transportation.

[0025] It is worth mentioning that the continuous rotation of the connecting rod 202 will cause the contact rod 314 to indirectly contact the movable sheet 313, which causes the cylindrical bracket 300 to have a small rotation offset. The movable sheet 313 is provided with a torsion spring at the connection point and its own rotation connection design, which can make the contact rod 314 transmit the movement of the movable sheet 313 when it first contacts the movable sheet 313 and then disengage from the contact rod 314, thereby completing its own small rotation, thereby driving the contact surface between the cylindrical bracket 300 and the cleaning strip 303 to change, so that the cleaning strip 303 The outer surface of the filter screen 301 can be cleaned comprehensively. At the same time, the cleaning strip 303 can be slightly displaced by the hollow spring rod 304 to pass over the blocking strip 302. When the dirt suction hole 311 sucks in impurities, it also absorbs a certain amount of ammonia water.

[0026] Specifically, when the ammonia water continuously passes through the filter chamber 200, the driving motor 201 is started to drive the connecting rod 202 to rotate. At this time, the moving blades of the blade assembly 203 connected to the connecting rod 202 will rotate while the stationary blades thereof will be stationary, so that the gas entering the air inlet valve 206 is gradually compressed and transported to the inside of the atomizing pipe 103 through the compressed air pipe 204 to be atomized. At the same time, the rotation of the connecting rod 202 will also drive the rotation of the plurality of flow delivery blades 312, thereby accelerating the efficiency of the ammonia water passing through the filter screen 301, thereby driving the roller 312 to rotate. 09 rotates to drive the roller 308 to rotate and drive the turbine 307 to rotate continuously, so that negative pressure is generated in the return trough 305, so that air is sucked from the inside of the cleaning strip 303 through the hollow spring rod 304, so that the multiple suction holes 311 suck away the debris attached to the outer surface of the filter screen 301 and transport it to the bottom of the filter chamber 200 through the return trough 305. At the same time, the rotation of the connecting rod 202 drives the resistance rod 314 to intermittently push the movable sheet 313 to move, thereby driving the cylindrical bracket 300 to be slightly displaced.

[0027] In summary, the driving motor 201 drives the blade assembly 203 to rotate, compresses the incoming gas, and sends the compressed gas into the atomizing tube 103 through the compressed gas pipe 204 to atomize the ammonia water. This design improves the atomization efficiency of the ammonia water and helps to spray the ammonia water more evenly. At the same time, the pressure gauge 205 can monitor the pressure value of the compressed gas in real time to ensure the stability of the atomization. The shunt pipe 102 and the flow meter 105: the partition of the ammonia water is controlled by the valve 104, and the flow meter 105 can accurately measure the ammonia flow of each partition to achieve precise metering, the cylindrical bracket 300 and its filter 301: the filter 301 can effectively block the impurities and particles in the ammonia water and improve the purity of the ammonia water, the cleaning strip 303 and the collection assembly cleaning strip 303 are tightly fitted with the filter 301, and the impurities are sucked into the return sewage tank 305 through the channel formed by the suction hole 311 and the hollow spring rod 304, which effectively prevents the filter 301 from being blocked and improves the filtering efficiency, the roller 309, the lifting sheet 310 and the turbine 307: the rotation of the roller 309 drives the turbine 307 to rotate continuously through the roller 308, thereby generating negative pressure and promoting the suction and discharge of impurities and a small amount of ammonia water. At the same time, the lifting piece 310 lifts the ammonia water below the cylindrical bracket 300 and flows back to the inside of the cylindrical bracket 300 through the filter screen 301 below, thereby realizing the recycling of the ammonia water and the multifunctional design of the driving motor 201 and the connecting rod 202: the connecting rod 202 not only drives the blade assembly 203 to compress the gas, but also drives the flow delivery blade 312 to accelerate the flow of ammonia water, and through the combined design of the roller 309, the resistance rod 314 and the movable piece 313, a small displacement of the cylindrical bracket 300 is realized to ensure that the cleaning strip 303 can fully clean the filter screen 301.

[0028] Example 2: Please refer to Figure 1-Figure 8 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: an automated zoning injection device for efficiently and accurately measuring ammonia water, further comprising a spray pipe 400, one end of which is fixedly connected to an atomizing pipe 103 connected to the shunt pipe 102, and the interior of the spray pipe 400 is provided with a plurality of nozzles 402 in a divergent shape along its center, and the plurality of nozzles 402 are used to spray ammonia water, and the interior of the spray pipe 400 is provided with an enhancement component for swinging the plurality of nozzles 402 to expand the spray range, and by setting the enhancement component, the plurality of nozzles 402 can be swung to expand the spray range of ammonia water, and accelerate its contact efficiency with pollutants in the exhaust gas, and at the same time, the plurality of nozzles 402 are in a divergent state to realize comprehensive angle injection, and in conjunction with its swinging action, its spray range can be further improved to fully contact with the exhaust gas.

[0029] Furthermore, the enhancement component includes a plurality of collars 407 arranged inside the injection pipe 400, and the outer surfaces of the plurality of collars 407 are provided with swing guide grooves 408. The outer surface of the injection pipe 400 is evenly and rotationally connected with a plurality of rotating tubes 410 connected with the nozzle 402, and the interiors of the plurality of swing guide grooves 408 are slidably connected with guide beads 412, and the tops of the guide beads 412 are rotatably connected with pull rings 411 sleeved on the outer surface of the rotating tube 410, and one end of the rotating tube 410 is fixedly connected with an air intake port 409 for inhaling ammonia water. By providing the swing guide groove 408, the pull ring 411 can be continuously driven to swing left and right under the rotation force of the collar 407, thereby driving the rotating tube 410 to rotate and change the injection angle of the nozzle 402. At the same time, the air intake port 409 is provided inside the injection pipe 400 to absorb the ammonia water passing through the inside of the injection pipe 400 and cause it to be ejected through the nozzle 402.

[0030] Among them, the interior of the injection tube 400 is rotatably connected with an inner guide tube 403 for fixing multiple rings 407, the interior of the inner guide tube 403 is fixedly connected with multiple tight holes 404, and the multiple tight holes 404 are used to accelerate the flow rate of ammonia water. The interior of the injection tube 400 is fixedly connected with a micro motor 405, and the output end of the micro motor 405 is fixedly connected with a connecting frame 406 fixedly connected to the inner guide tube 403. By setting the tight holes 404 in the inner guide tube 403, the flow rate of ammonia water can be accelerated, and then it will flow back through the inner guide tube 403 to between the injection tube 400 and the inner guide tube 403 and be discharged through multiple air intake ports 409.

[0031] Specifically, the atomized ammonia water will first pass through the inner guide tube 403 when entering the injection tube 400. At the same time, the multiple tight holes 404 can accelerate the flow rate of the ammonia water, so that it enters between the inner guide tube 403 and the injection tube 400. At the same time, the micro motor 405 is turned on to drive the connecting frame 406 to rotate and drive the inner guide tube 403 to rotate inside the injection tube 400. At this time, the rotation of the inner guide tube 403 will drive the multiple rings 407 to rotate together. At this time, the swinging guide groove 408 will continuously push the guide bead 412 to be dislocated, and then the pull ring 411 drives the rotating tube 410 to rotate and swing, so that the ammonia water enters the air intake port 409 and is sprayed out through the nozzle 402, thereby increasing its spray range.

[0032] In summary, the inner guide tube 403 rotates to drive the collar 407 to rotate together, and then the guide bead 412 is displaced through the swing guide groove 408, so that the pull ring 411 drives the rotating tube 410 to rotate and swing. This design enables the nozzle 402 to continuously change the spray angle, thereby expanding the spray range of ammonia water and accelerating its contact efficiency with pollutants in the exhaust gas. The nozzles 402 are not only numerous, but also divergently arranged, which can achieve comprehensive angle spraying under the action of the synergistic component, further improve the spray range, and ensure that ammonia water can fully contact the exhaust gas. The micro motor 405 drives the connecting frame 406 to rotate, thereby driving the inner guide tube 403 to rotate. This design not only realizes the function of the synergistic component, but also ensures the efficient flow of ammonia water between the inner guide tube 403 and the spray tube 400. The flow rate of ammonia water is accelerated by the tight hole 404, so that more ammonia water can enter the injection area, and the utilization rate of ammonia water is improved. The inner guide tube 403 and the tight hole 404: the tight hole 404 in the inner guide tube 403 not only accelerates the flow rate of ammonia water, but also makes the ammonia water fully dispersed and uniform before entering the injection area. This design helps to optimize the injection effect, so that ammonia water can be more evenly distributed in the exhaust gas, improve the desulfurization and denitrification efficiency, and cooperate with the filter chamber 200 and the diverter pipe 102: the filter chamber 200 ensures the purity of ammonia water, and the diverter pipe 102 realizes the precise measurement of ammonia water. The injection pipe 400 and its synergistic components further inject pure and accurately measured ammonia water into the exhaust gas in the best way, realizing comprehensive optimization and control from the source to the injection terminal.

[0033] Example 3: Please refer to Figures 1 to 15 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: an automated partition injection method for efficient and accurate metering of ammonia water, comprising the following steps: S1. When in use, firstly, the ammonia water is poured into the interior of the ammonia water main pipe 101, then flows through the plurality of branch pipes 102 and passes through the filter chamber 200. When the ammonia water passes through the interior of the filter chamber 200, it passes through the filter screen 301 for filtration, then flows into the interior of the atomizing pipe 103 and is sprayed out through the spray pipe 400. S2. When the ammonia water continuously passes through the filter chamber 200, the driving motor 201 is started to drive the connecting rod 202 to rotate. At this time, the moving blades of the blade assembly 203 connected to the connecting rod 202 will rotate while the stationary blades will be stationary, so that the gas entering the air inlet valve 206 is gradually compressed and transported to the inside of the atomizing pipe 103 through the compressed air pipe 204 to be atomized. At the same time, the rotation of the connecting rod 202 will also drive the rotation of the plurality of flow delivery blades 312 to accelerate the efficiency of the ammonia water passing through the filter screen 301, thereby driving the roller 312 to rotate. 09 rotates to drive the roller 308 to rotate and drive the turbine 307 to rotate continuously, so that negative pressure is generated in the return trough 305, so that air is sucked from the inside of the cleaning strip 303 through the hollow spring rod 304, so that the multiple suction holes 311 suck away the debris attached to the outer surface of the filter screen 301 and transport it to the bottom of the filter chamber 200 through the return trough 305. At the same time, the rotation of the connecting rod 202 drives the resistance rod 314 to intermittently push the movable sheet 313 to move, thereby driving the cylindrical bracket 300 to be slightly displaced; S3. The atomized ammonia water will first pass through the inner guide tube 403 when entering the injection tube 400. At the same time, the multiple tight holes 404 can speed up the flow rate of the ammonia water, so that it enters between the inner guide tube 403 and the injection tube 400. At the same time, the micro motor 405 is turned on to drive the connecting frame 406 to rotate and drive the inner guide tube 403 to rotate inside the injection tube 400. At this time, the rotation of the inner guide tube 403 will drive the multiple rings 407 to rotate together. At this time, the swinging guide groove 408 will continuously push the guide bead 412 to be misaligned, and then the pull ring 411 drives the rotating tube 410 to rotate and swing, so that the ammonia water enters the air intake port 409 and is sprayed out through the nozzle 402, thereby increasing its spraying range.
