Abstract
Description
Technical Field
[0001] This application relates to the field of flue gas purification equipment technology, and in particular to an adaptive and intelligent anti-clogging and demisting system. Background Technology
[0002] In wet desulfurization systems, demister clogging is the core issue leading to increased system resistance and reduced demister efficiency. Currently, the mainstream anti-clogging method in the industry is to passively increase the flushing frequency: when an increase in demister pressure differential is detected, the flushing interval is shortened (e.g., from 120 minutes / time to 60 minutes / time) and the duration of a single flush is extended (e.g., from 60 seconds to 120 seconds) to flush away the scale buildup between the plates with high-pressure water flow.
[0003] The aforementioned technologies have several significant drawbacks: 1. Severe water waste: High-frequency flushing increases the water replenishment volume of the desulfurization system by 20%-40%, resulting in some power plants consuming hundreds of tons more water per day, which does not comply with the "water conservation and emission reduction" policy; 2. Difficulty in controlling the water balance of the desulfurization tower: High-frequency high-pressure flushing can cause the amount of water evaporated from the desulfurization system to be less than the amount of water replenished during flushing, disrupting the water balance of the entire desulfurization system; 3. Risk of secondary pollution: Excessive flushing water carrying slurry back to the desulfurization tower will dilute the absorbent concentration, increase the consumption of desulfurizing agent, and increase the wastewater treatment load; 4. Delayed adjustment: Relying solely on the passive logic of "flushing only after the pressure difference exceeds the standard" makes it impossible to predict the clogging trend in advance, easily leading to the dilemma of "untimely flushing causing increased clogging" or "blind flushing causing resource waste". Summary of the Invention
[0004] To address the shortcomings of existing anti-clogging demisters in terms of poor adaptability to operating conditions, this application provides an adaptive and intelligent anti-clogging demister system.
[0005] The adaptive intelligent anti-clogging and defogging system provided in this application adopts the following technical solution: An adaptive intelligent anti-clogging defogging system includes: A ridge-type frame, wherein multiple strip-shaped adjustment grooves are provided on the ridge-type frame; Multiple baffle bodies are distributed along the opening direction of the strip-shaped adjusting groove. A flow channel is formed between two adjacent baffle bodies and at least one isolation element is provided. The ends of the baffle bodies and the ends of the isolation elements both extend into the strip-shaped adjusting groove. An adjustable separation assembly is connected to the ridge frame. The adjustable separation assembly slides within the strip-shaped adjustment groove and is capable of abutting against the ends of the baffle body and the isolation element that extend into the strip-shaped adjustment groove, so that the baffle body and the isolation element move along the opening direction of the strip-shaped adjustment groove.
[0006] By adopting the above technical solution, the adjustable separation component applies force to the isolation element, causing the isolation element to slide along the opening direction of the strip-shaped adjustment groove until the isolation element abuts against the baffle plate body. Then, it applies force to the baffle plate body, causing the baffle plate body to overcome the sliding resistance and slide along the opening direction of the strip-shaped adjustment groove. This allows for the adjustment of the distance between two adjacent baffle plates, thus adapting to flue gas velocity fluctuations of 4m / s to 7m / s and dust content of 5mg / m³ to 30mg / m³. This improves the poor adaptability of the anti-clogging demister and keeps the demisting efficiency stably above 99.5%.
[0007] In one specific implementation, the adjustable separation component includes: Multiple electromagnetically driven sliders slide within the strip-shaped adjustment groove, and the electromagnetically driven sliders are capable of abutting against the ends of the baffle body and the isolation element that extend into the strip-shaped adjustment groove.
[0008] By adopting the above technical solution, the sliding of the baffle body and the isolation element can be achieved by using an electromagnetically driven slider in conjunction with a ridge frame made of metal material such as 304 stainless steel, thereby realizing the adjustment of the distance between two adjacent baffle bodies.
[0009] In one specific implementation, the baffle body includes a first curvature arc segment arranged in a sinusoidal curve, and a curvature fine-tuning component is connected to the first curvature arc segment. The curvature fine-tuning component includes: A deformable arc sheet, wherein the deformable arc sheet is connected to the first curvature arc segment, and the deformable arc sheet is an elastic stainless steel sheet with a thickness between 0.5 mm and 1 mm; Two miniature push rods are connected to the first curvature arc segment and to the deformable arc plate, so as to change the wavelength of the first curvature arc segment through the deformable arc plate.
[0010] By adopting the above technical solution, the miniature push rod applies force to the deformable arc plate, causing the deformable arc plate to deform. At the same time as the deformable arc plate deforms, it drives the first curvature arc segment to deform, thereby changing the wavelength of the first curvature arc segment, and thus adapting to the fluctuating working conditions of flue gas velocity of 4m / s~7m / s and dust content of 5mg / m³~30mg / m³.
[0011] In one specific implementation, the wavelength of the first curvature arc segment is between 60 mm and 110 mm.
[0012] By adopting the above technical solution, the intensity of centrifugal collision of droplets can be changed.
[0013] In one specific implementation, the crest of the first curvature arc segment is smoothly connected to a second curvature arc segment, and the angle between the first curvature arc segment and the second curvature arc segment is 30 degrees to 60 degrees.
[0014] In one specific implementation, a targeted precision flushing component is also included, the targeted precision flushing component comprising: Multiple angled nozzles are connected to the ridge frame, and the angle between the axis of the angled nozzle and the tangent of the trough of the first curvature arc segment is between 30 degrees and 45 degrees. Multiple flat nozzles are connected to the ridge frame. Multiple angled nozzles are connected in series to form a first line, and multiple flat nozzles are connected in series to form a second line. The baffle body is located between the first line and the second line.
[0015] By adopting the above technical solution, the designed targeted precision flushing component can achieve cleaning of the baffle plate body through the combination of angled nozzles and flat nozzles.
[0016] In one specific implementation, both the baffle body and the isolation element have hook-shaped portions extending smoothly outward at their ends, and an oblong hole is formed between the isolation element and the hook-shaped portion, with the flat nozzle facing the oblong hole.
[0017] By adopting the above technical solution, the cleaning fluid sprayed from the flat nozzle can clean the hook-shaped part along the flow channel.
[0018] In one specific implementation scheme, an online monitoring intelligent control component is also included, the online monitoring intelligent control component comprising: Multiple droplet concentration sensors are connected to the ridge frame, and the droplet concentration sensors are located at the inlet and outlet of the flow channel; Multiple flow channel pressure sensors are connected to the ridge frame and are arranged along the extension direction of the flow channel. Multiple flue gas parameter sensors are connected to the ridge frame, and the flue gas parameter sensors are located near the inlet of the flow channel; The intelligent control module is electrically connected to the adjustable separation component, the micro push rod, the droplet concentration sensor, the flow channel pressure sensor, the flue gas parameter sensor, and the targeted precision flushing component.
[0019] By adopting the above technical solution, the flue gas parameter sensor collects D=25mg / m³ and V=6.5m / s, and uploads them to the intelligent control module. The intelligent control module judges it as a "high dust and high flow rate condition" and drives the electromagnetic drive slider to slide along the strip adjustment groove, adjusting the distance between the baffle bodies from the initial 80mm to 100mm. At the same time, it controls the micro push rod to retract, adjusting the wavelength of the first curvature arc segment from 80mm to 70mm. After adjustment, the flow channel pressure sensor monitors ΔP decreasing from 180Pa to 140Pa, and the outlet droplet concentration sensor monitors C_out decreasing from 18mg / m³ to 10mg / m³, and the system operates stably. After running for a period of time, the flow channel pressure sensor monitors ΔP rising to 220Pa, and the outlet C_out rising to 16mg / m³. If the flue gas parameter sensor collects D=15mg / m³ and V=5.5m / s, and uploads this data to the intelligent control module, the intelligent control module determines it to be a "medium dust content, medium flow rate condition." It then drives the electromagnetic drive slider to slide along the strip-shaped adjustment groove, adjusting the distance between the baffle plates to 60mm. Simultaneously, it controls the micro push rod to retract, adjusting the wavelength of the first curvature arc segment to 95mm. If the flue gas parameter sensor collects D=5mg / m³ and V=4m / s, and uploads this data to the intelligent control module, the intelligent control module determines it to be a "low dust content, low flow rate condition." It then drives the electromagnetic drive slider to slide along the strip-shaped adjustment groove, adjusting the distance between the baffle plates to 45mm. Simultaneously, it controls the micro push rod to retract, adjusting the wavelength of the first curvature arc segment to 110mm. If the intelligent control module determines that "fouling is the primary cause," it prioritizes targeted flushing: first, it activates the angled nozzle (flushing flow rate 12L / min, continuous for 3 minutes, nozzle pressure 0.3MPa) to flush the trough of the first curvature arc segment; then, it activates the low-pressure flat nozzle (flushing flow rate 8L / min, continuous for 2 minutes, nozzle pressure 0.15MPa) to flush the hook-shaped grooves; after flushing, ΔP drops to 130Pa, C drops to 9mg / m³, and the system returns to normal operation. If ΔP remains at 210Pa after targeted flushing, the intelligent control module determines that "the flow channel is severely blocked," triggers the control cabinet's audible and visual alarm, and sends a "manual inspection of the baffle clearance is required" message to the maintenance terminal via the 4G module; maintenance personnel inspect on-site and find that the oblong hole on the isolation element is stuck. After cleaning, the system returns to normal, avoiding downtime.
[0020] In one specific implementation scheme, electromagnetic flow valves are flange-connected to both the series pipelines of the multiple angled nozzles and the series pipelines of the multiple flat nozzles, and the electromagnetic flow valves are electrically connected to the intelligent control module.
[0021] By adopting the above technical solution, it can be used in conjunction with an intelligent control module to adjust the flushing flow rate (5L / min~15L / min) according to changes in flow channel resistance, thus avoiding ineffective flushing.
[0022] In one specific implementation, the spray pressure of the angled nozzle is between 0.2 MPa and 0.4 MPa, the spray pressure of the flat nozzle is between 0.1 MPa and 0.2 MPa, and the water mist thickness is no more than 5 mm.
[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. The designed adaptive intelligent anti-clogging demister system uses an adjustable separation component to apply force to the isolation element, causing the isolation element to slide along the opening direction of the strip-shaped adjustment groove until it comes into contact with the baffle plate body. Then, the isolation element applies force to the baffle plate body, causing it to overcome sliding resistance and slide along the opening direction of the strip-shaped adjustment groove. This allows for adjustment of the distance between two adjacent baffle plates, thus adapting to flue gas velocity fluctuations of 4m / s to 7m / s and dust content of 5mg / m³ to 30mg / m³. This improves the poor adaptability of the anti-clogging demister and ensures that the demister efficiency remains stable at over 99.5%.
[0024] 2. The designed adaptive intelligent anti-clogging and demisting system, with its precise targeted flushing components, cleans key areas of accumulated dirt such as the troughs of the first curvature arc segment and the grooves of the hook-shaped part, improving flushing efficiency by 40%, extending the flow channel clogging cycle, and reducing the number of downtime flushing times. 3. The designed adaptive intelligent anti-clogging defogging system achieves "on-demand adjustment and precise flushing" through online monitoring and linkage control, eliminating the need for manual inspection and reducing operation and maintenance costs by 30%. At the same time, it provides early warning through fault diagnosis to avoid sudden decline in defogging efficiency. 4. The designed adaptive intelligent anti-clogging and demisting system can directly modify the demister (by adding curvature fine-tuning components, targeted precision flushing components, and online monitoring and intelligent control components) without replacing the ridge frame and baffle body. The modification cost is low and it is suitable for upgrading the desulfurization tower of old units. Attached Figure Description

Detailed implementation manners
[0032] The following further elaborates on this application in conjunction with Figure 1-6 the attached drawings.
[0033] The embodiment of this application discloses an intelligent anti - clogging demisting system with adaptive adjustment.
[0034] Referring to Figure 1 and Figure 2 An intelligent anti - clogging demisting system with adaptive adjustment includes a ridge - type frame 1, a baffle plate body 2, and an isolation element 3. The ridge - type frame 1 is arranged in a "human" shape. Multiple strip - shaped adjustment chutes 11 are provided on the ridge - type frame 1. The number of baffle plate bodies 2 is multiple, and the multiple baffle plate bodies 2 are divided into two groups and arranged on the left and right sides of the ridge - type frame 1. The multiple baffle plate bodies 2 in the same group are distributed along the opening direction of the strip - shaped adjustment chutes 11, and the baffle plate body 2 is slidably connected to the ridge - type frame 1 through a damping structure. A flow channel is formed between adjacent two baffle plate bodies 2. The number of isolation elements 3 is at least one, and the number of isolation elements 3 between adjacent two baffle plate bodies 2 is at least one. The isolation element 3 is used to divide the flow channel.
[0035] Referring to Figure 1 and Figure 2To adapt to different operating conditions, an adjustable separation component 4 is also included. The adjustable separation component 4 is connected to the ridge frame 1 and slides within the strip-shaped adjustment groove 11. The adjustable separation component 4 can abut against the ends of the baffle body 2 and the isolation element 3 that extend into the strip-shaped adjustment groove 11, so that the baffle body 2 and the isolation element 3 can move along the opening direction of the strip-shaped adjustment groove 11, thereby adjusting the distance between two adjacent baffle bodies 2. The adjustable separation component 4 applies force to the isolation element 3 to make the isolation element... 3. Slide along the opening direction of the strip-shaped adjustment groove 11 until the isolation element 3 abuts against the baffle plate body 2 and applies force to the baffle plate body 2, so that the baffle plate body 2 overcomes the sliding resistance and slides along the opening direction of the strip-shaped adjustment groove 11, thereby realizing the adjustment of the distance between two adjacent baffle plate bodies 2, thus adapting to the flue gas velocity of 4m / s~7m / s and dust content of 5mg / m³~30mg / m³, improving the problem of poor adaptability of the anti-clogging demister, and making the demisting efficiency stably maintained above 99.5%.
[0036] Reference Figure 2 Specifically, the adjustable separation component 4 includes multiple electromagnetically driven sliders 41. The electromagnetically driven sliders 41 slide within the strip-shaped adjustment groove 11. The ends of the baffle body 2 and the isolation element 3 both extend into the strip-shaped adjustment groove 11. Therefore, when the electromagnetically driven sliders 41 slide within the strip-shaped adjustment groove 11, they can abut against the baffle body 2 or the isolation element 3, thereby causing the baffle body 2 or the isolation element 3 to slide along the opening direction of the strip-shaped adjustment groove 11, so that the distance between two adjacent baffle bodies 2 is within the range of 45mm to 120mm. The electromagnetically driven sliders 41 can cooperate with the ridge frame 1 made of metal material such as 304 stainless steel to realize the sliding of the baffle body 2 and the isolation element 3, thereby realizing the adjustment of the distance between two adjacent baffle bodies 2. The distance between two adjacent baffle bodies 2 is proportional to the flow rate of the gas and the dust content in the flow channel.
[0037] Reference Figure 2 and Figure 3 Furthermore, the baffle body 2 includes an inlet section, a first curvature arc section 21, and an outlet section arranged sequentially. The inlet section is arranged along the flow direction of the gas-liquid mixture in the flow channel. The first curvature arc section 21 is a sine wave curve. The peak of the first curvature arc section 21 is smoothly connected to the second curvature arc section 22. The included angle between the first curvature arc section 21 and the second curvature arc section 22 is 30 degrees to 60 degrees. The outlet section has the same radius of curvature as the arc surface of the isolation element 3. The first curvature arc section 21 is made of stainless steel.
[0038] Reference Figure 2 and Figure 3Specifically, it also includes a curvature fine-tuning component 5, which includes a deformable arc plate 51 and two micro push rods 52. The deformable arc plate 51 is fixedly connected to the first curvature arc segment 21 by screws, adhesive, or other means. The micro push rods 52 are connected to the first curvature arc segment 21 and the deformable arc plate 51. The micro push rods 52 at both ends simultaneously apply force to the deformable arc plate 51, causing the deformable arc plate 51 to deform and thus change the wavelength of the first curvature arc segment 21. The deformable arc plate 51 has a thickness between 0.5 mm and 1 mm. The flexible stainless steel sheet is made of mm; and the wavelength of the first curvature arc segment 21 is between 60 mm and 110 mm; wherein, the wavelength of the first curvature arc segment 21 is inversely proportional to the gas flow velocity and the dust content of the gas in the flow channel; the micro push rod 52 applies force to the deformable arc plate 51, causing the deformable arc plate 51 to deform, and at the same time the deformable arc plate 51 deforms, it drives the first curvature arc segment 21 to deform, thereby changing the wavelength of the first curvature arc segment 21, and thus adapting to the flue gas flow velocity of 4m / s~7m / s and the dust content of 5mg / m³~30mg / m³.
[0039] Reference Figure 4 Furthermore, it also includes a targeted precision flushing component 6, which includes multiple angled nozzles 61 and multiple flat nozzles 62. The multiple angled nozzles 61 are distributed along the opening direction of the strip-shaped adjustment groove 11, and the angled nozzles 61 are connected to the ridge frame 1. The angle between the axis of the angled nozzles 61 and the tangent of the trough of the first curvature arc segment 21 is between 30 degrees and 45 degrees. The multiple flat nozzles 62 are distributed along the opening direction of the strip-shaped adjustment groove 11, and the multiple angled nozzles 61 are connected in series through infusion pipes to form a first line. The multiple flat nozzles 62 are connected in series through infusion pipes to form a second line. The baffle body 2 is located between the first line and the second line.
[0040] Reference Figure 2 and Figure 4 Specifically, both the baffle body 2 and the isolation element 3 have hook-shaped portions 7 extending smoothly outwards at their ends, and an oblong hole is formed between the isolation element 3 and the hook-shaped portion 7. The flat nozzle 62 is positioned towards the oblong hole, meaning that the cleaning fluid sprayed by the flat nozzle 62 can complete the rinsing work of the oblong hole. More specifically, the spray pressure of the angled nozzle 61 is between 0.2 MPa and 0.4 MPa, the angled nozzle 61 uses a fan-shaped water mist, and its atomization angle is preferably 60°. The spray pressure of the flat nozzle 62 is between 0.1 MPa and 0.2 MPa, and the thickness of the water mist sprayed by the flat nozzle 62 is no more than 5 mm.
[0041] Reference Figure 4Based on the aforementioned scheme, an electromagnetic flow valve 63 is flanged and connected to the series infusion pipeline of multiple inclined nozzles 61, and an electromagnetic flow valve 63 is also flanged and connected to the series infusion pipeline of multiple flat nozzles 62; it can cooperate with the intelligent control module 84 to adjust the flushing flow rate (5L / min~15L / min) according to the change of flow channel resistance to avoid ineffective flushing.
[0042] Reference Figure 5 Furthermore, it also includes an online monitoring intelligent control component 8, which includes a droplet concentration sensor 81, a flow channel pressure sensor 82, a flue gas parameter sensor 83, and an intelligent control module 84. There are multiple droplet concentration sensors 81, which are connected to the ridge frame 1 and are located at the inlet and outlet of the flow channel. There are multiple flow channel pressure sensors 82, which are connected to the ridge frame 1 and are arranged along the extension direction of the flow channel. There are multiple flue gas parameter sensors 83, which are connected to the ridge frame 1 and are located near the inlet of the flue in the flow channel. The intelligent control module 84 is electrically connected to the electromagnetic drive slider 41, the miniature push rod 52, the droplet concentration sensor 81, the flow channel pressure sensor 82, the flue gas parameter sensor 83, and the electromagnetic flow valve 63.
[0043] Reference Figure 5 and Figure 6 Furthermore, this application also discloses the control logic of the intelligent control module 84 as follows: Inlet and outlet droplet concentration sensors 81: installed at the flue gas inlet of the demisting system, i.e., near the inlet section, and at the outlet, i.e., near the top of the roof frame 1, respectively, with a detection accuracy ≤5μm, to collect droplet concentration in real time, denoted as Cin and Cout; Flow channel pressure sensors 82: three sets are evenly arranged along the baffle flow channel, one set each at the inlet section, the first curvature arc section 21, and the outlet section, to monitor the real-time pressure difference in the flow channel, denoted as ΔP; Flue gas parameter sensors 83 are installed in the inlet flue, collecting flue gas temperature (T), flow velocity (V), and dust content (D); when V > 6m / s or D > 6m / s, the sensor detects the flue gas temperature (T), flow velocity (V), and dust content (D). When the concentration is >20mg / m³, the electromagnetic drive slider 41 is driven to increase the spacing between the baffle bodies 2 to 80mm~120mm. At the same time, the wavelength of the first curvature arc segment 21 is reduced to 60mm~80mm by the micro push rod 52 to enhance the centrifugal collision of droplets. When ΔP>200Pa or Cout>15mg / m³, it is judged to be due to scale buildup or insufficient flow channel adaptation. If ΔP increases, targeted flushing is initiated first, that is, the trough of the first curvature arc segment 21 is flushed first, and then the waist-shaped holes at the hook-shaped part 7 are flushed. If Cout increases, the flow channel parameters are adjusted first. After flushing, if ΔP is still >150Pa, an audible and visual alarm is triggered and a maintenance prompt is pushed to the terminal.
[0044] The implementation principle of an adaptive adjustment intelligent anti-clogging and demisting system according to an embodiment of this application is as follows: The flue gas parameter sensor 83 collects D=25mg / m³ and V=6.5m / s, and uploads it to the intelligent control module 84; the intelligent control module 84 determines that it is a "high dust and high flow rate condition", drives the electromagnetic drive slider 41 to slide along the strip adjustment groove 11, and adjusts the spacing of the baffle body 2 from the initial 80mm to 100mm; at the same time, it controls the micro push rod 52 to retract, and adjusts the wavelength of the first curvature arc segment 21 from 80mm to 70mm; after adjustment, the flow channel pressure sensor 82 monitors ΔP to decrease from 180Pa to 140Pa, and the outlet droplet concentration sensor 81 monitors C to decrease from 18mg / m³ to 10mg / m³, and the system operates stably; after running for a period of time, the flow channel pressure sensor 82 monitors ΔP to rise to 220Pa, and the outlet C rises to 16mg / m³.
[0045] If the flue gas parameter sensor 83 collects D=15mg / m³ and V=5.5m / s, and uploads it to the intelligent control module 84, the intelligent control module 84 determines that it is a "medium dust and medium flow rate condition", drives the electromagnetic drive slider 41 to slide along the strip adjustment groove 11, adjusts the spacing of the baffle body 2 to 60mm, and at the same time controls the micro push rod 52 to retract, adjusting the wavelength of the first curvature arc segment 21 to 95mm.
[0046] If the flue gas parameter sensor 83 collects D=5mg / m³ and V=4m / s, and uploads it to the intelligent control module 84, the intelligent control module 84 determines that it is a "low dust and low flow rate condition", drives the electromagnetic drive slider 41 to slide along the strip adjustment groove 11, adjusts the spacing of the baffle body 2 to 45mm, and at the same time controls the micro push rod 52 to retract, adjusting the wavelength of the first curvature arc segment 21 to 110mm.
[0047] If the intelligent control module 84 determines that "fouling is the main cause", it will prioritize targeted flushing: first, open the angled nozzle 61 (flushing flow rate 12L / min, continuous for 3min, nozzle pressure 0.3MPa) to flush the first curvature arc segment 21 trough; then open the low-pressure flat nozzle 62 (flushing flow rate 8L / min, continuous for 2min, nozzle pressure 0.15MPa) to flush the hook-shaped part 7 groove; after flushing, ΔP drops to 130Pa, C drops to 9mg / m³, and the system returns to normal operating conditions.
[0048] If ΔP remains at 210Pa after targeted flushing, the intelligent control module 84 determines that "the flow channel is severely blocked", triggers the audible and visual alarm of the control cabinet, and sends a prompt "manual inspection of the baffle plate gap is required" to the maintenance terminal via the 4G module. The maintenance personnel found that the waist-shaped hole on the isolation element 3 was stuck. After cleaning, the system returned to normal, avoiding downtime accidents.
[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
