Description

Technical Field

[0001] This utility model relates to a corrosion-resistant wet electrostatic precipitator electrode plate assembly, belonging to the technical field of dust collector electrode plates. Background Technology

[0002] Wet electrostatic precipitators are widely used in coal-fired power plants, steel metallurgy, chemical and other industrial fields for the deep removal of fine particulate matter (PM2.5), acid mist and heavy metal pollutants from flue gas. Their core component—the electrode plate assembly—is exposed to a high-humidity, acidic, and corrosive environment, requiring both high dust collection efficiency and corrosion resistance. Traditional electrode plates are often made of stainless steel or fiberglass, but these materials are prone to efficiency degradation due to acid corrosion, particle erosion, and surface scaling during long-term operation. Furthermore, the fixed structure makes efficient cleaning difficult, necessitating frequent shutdowns for maintenance.

[0003] Existing wet electrostatic precipitator electrode plate assemblies are prone to pitting corrosion and stress corrosion in acidic wet flue gas due to the use of traditional stainless steel or fiberglass electrode plates. The coating peeling rate is high, which leads to a shortened lifespan and frequent replacement. They also have poor corrosion resistance.

[0004] Conventional spray systems can only rinse fixed electrode plates in one direction. The fixed tilt angle structure cannot adapt to complex scaling patterns, resulting in cleaning blind spots. This requires increasing the spray frequency or manual intervention, which increases energy consumption and maintenance costs.

[0005] Therefore, the purpose of this study is to design an adaptive cleaning and corrosion-resistant wet electrode assembly that combines high efficiency and corrosion resistance with dynamic adjustment function. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a corrosion-resistant wet electrostatic precipitator electrode plate assembly to solve the problems of the existing technology.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0008] A corrosion-resistant wet electrostatic precipitator electrode plate assembly includes: a frame, a set of support rods fixedly installed in the lower region inside the frame, a set of adjusting rods slidably installed in the upper region inside the frame, a power assembly for driving the adjusting rods to slide, and a plurality of electrode plates vertically and equidistantly arranged inside the frame.

[0009] The lower ends of the plurality of electrode plates are rotatably mounted on the two support rods, and the upper ends of the plurality of electrode plates are movably mounted on the two adjusting rods;

[0010] Several sets of spray heads are arranged inside the frame, and the spray heads are located directly above the connection between the electrode plate and the support rod.

[0011] The power assembly controls the adjusting rod to drive multiple electrode plates. With the connection between the electrode plates and the support rod as the axis, the electrode plates move upwards to the left / right, forming a left / right tilted posture, which is used in conjunction with the spray head above for cleaning.

[0012] The electrode plate is made of titanium alloy or stainless steel substrate, and the surface of the electrode plate is coated with a boron diamond conductive ceramic layer.

[0013] As a further improvement, the narrow side of the frame facing the electrode plate is closed, and the wide side of the frame facing the electrode plate is open. The open side of the frame is an air inlet, and the open side is an air outlet. The frame is a welded frame of 316L stainless steel or titanium alloy, and the surface is coated with an epoxy glass flake anti-corrosion layer.

[0014] As a further improvement, the inner side of the support rod is provided with several slots, and a first rotating shaft is provided on the lower side of the electrode plate protruding outward. The first rotating shaft is inserted into the slot to achieve a rotatable connection.

[0015] As a further improvement, the support rod is made of solid titanium alloy cylinder, and several slots with a depth of 5-8mm are equally spaced along the axial direction of the support rod. The width of the slots is slightly larger than the diameter of the first rotating shaft, and the spacing between the slots is consistent with the spacing of the electrode plates.

[0016] As a further improvement, a first rotating shaft with a diameter of Φ10~15mm is welded to the lower side of the electrode plate, and the first rotating shaft is perpendicular to the plane of the electrode plate.

[0017] A corrosion-resistant bearing is installed in the slot, and the first rotating shaft is inserted into the slot and fixed inside the corrosion-resistant bearing.

[0018] As a further improvement, a guide groove is vertically provided on the side of the adjusting rod, and a second rotating shaft is provided protruding outward on the upper side of the electrode plate. The second rotating shaft is inserted into the guide groove, so that when the power component controls the adjusting rod to drive the electrode plate to deflect and move, the electrode plate can maintain the connection with the adjusting rod.

[0019] As a further improvement, the adjusting rod is made of hollow aluminum alloy square tube, with a guide shaft passing through the inside of the aluminum alloy square tube, and both ends are slidably mounted on the slide rails above the frame.

[0020] As a further improvement, the power assembly includes an electric push rod mounted on the top of the frame, the end of which is hinged to the end of an adjusting rod via a universal coupling.

[0021] As a further improvement, the deflection angle of the electrode plate is ±15°.

[0022] As a further improvement, it also includes placing several sets of corona wires located on the central axis of the gap between the two electrode plates, and enhancing particle charging through the ion flow generated by the corona discharge of the corona wires.

[0023] Beneficial effects:

[0024] This invention addresses the problems of poor corrosion resistance, scaling and clogging, low cleaning efficiency, and lack of dynamic adjustment in existing technologies through three core components: a dynamically tilted electrode plate structure, a boron diamond conductive ceramic coating, and a linked spray head. Specifically:

[0025] Traditional stainless steel or fiberglass electrode plates are prone to pitting corrosion and stress corrosion in acidic humid flue gas, resulting in a high coating peeling rate.

[0026] By using titanium alloy or duplex stainless steel as the electrode plate substrate, the electrode plate is provided with basic corrosion resistance. A boron diamond conductive ceramic layer with a thickness of 200~300μm is sprayed on the substrate surface and a dense structure is formed by supersonic flame spraying process. Its acid and alkali resistance life is more than 8 years, which far exceeds the 3~5 years of traditional coatings.

[0027] This achieves a surface resistivity of ≤10Ω·cm for the electrode plates, meeting the requirements for electric field conductivity, and resistance to sulfuric acid concentration ≤80%, as well as resistance to Cl. - F - It has more than 3 times the corrosion resistance, Vickers hardness ≥2500HV, and significantly enhanced resistance to particle erosion and wear.

[0028] Because the gaps between fixed electrode plates are prone to scaling due to residual salt or dust accumulation caused by droplet evaporation, airflow deviation can occur.

[0029] By cooperating with the slot of the support rod and the guide slot of the adjustment rod, the electrode plate can be dynamically tilted by ±15°. The power component (electric push rod) drives the adjustment rod to slide, causing the electrode plate to tilt around the support rod as the axis, changing the shape of the airflow channel and disrupting the stable conditions for scale formation.

[0030] This allows the inclined structure to disrupt the liquid film boundary layer separation, reduce salt deposition in localized dry areas, dynamically disturb the airflow path, prevent dust from accumulating in fixed gaps, reduce scaling by 70%, and reduce cleaning frequency to 1 / 3 of the original.

[0031] Fixed spray systems cannot thoroughly clean complex scale formations, leaving blind spots.

[0032] The spray head is positioned directly above the connection between the electrode plate and the support rod, covering the easily scaled area at the base of the electrode plate. The power unit and the spray head are linked periodically, with the tilt angle synchronized with the spraying action. Every 10 seconds of spraying, the electrode plate tilts by 5°, causing the droplets to flow faster along the tilted surface, flushing out dead corners. The tilt angle is also switched cyclically within ±15° to achieve multi-angle cleaning. Attached Figure Description

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0044] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0045] Reference Figure 1-8 As shown, a corrosion-resistant wet electrostatic precipitator electrode plate assembly includes: a frame 1, a set of support rods 2 fixedly installed in the lower region inside the frame 1, a set of adjusting rods 3 slidably installed in the upper region inside the frame 1, a power assembly for driving the adjusting rods 3 to slide, and a plurality of electrode plates 4 vertically and equidistantly arranged inside the frame 1.

[0046] The lower ends of the plurality of electrode plates 4 are rotatably mounted on the two support rods 2, and the upper ends of the plurality of electrode plates 4 are movably mounted on the two adjusting rods 3;

[0047] Several sets of spray heads 5 are arranged inside the frame 1, and the spray heads 5 are located directly above the connection between the electrode plate 4 and the support rod 2;

[0048] The power assembly controls the adjusting rod 3 to drive multiple electrode plates 4. With the connection between the electrode plates 4 and the support rod 2 as the axis, the electrode plates 4 move upwards to the left / right, forming a left / right tilted posture, which is used in conjunction with the spray head 5 above for cleaning.

[0049] The electrode plate 4 is made of titanium alloy or stainless steel substrate, and the surface of the electrode plate 4 is coated with boron diamond conductive ceramic layer 41.

[0050] Through the three core components of the dynamically tilted electrode plate 4, the boron diamond conductive ceramic coating, and the linked spray head 5, this technology effectively addresses issues such as poor corrosion resistance, scaling and clogging, low cleaning efficiency, and lack of dynamic adjustment in existing technologies. Specifically:

[0051] Traditional stainless steel or fiberglass electrode plates 4 are prone to pitting corrosion and stress corrosion in acidic wet flue gas, resulting in a high coating peeling rate.

[0052] By using titanium alloy or duplex stainless steel as the substrate of electrode plate 4, the basic corrosion resistance of electrode plate 4 is provided. A boron diamond conductive ceramic layer 41 with a thickness of 200~300μm is sprayed on the surface of the substrate and a dense structure is formed by supersonic flame spraying process. Its acid and alkali resistance life is more than 8 years, which is far longer than the 3~5 years of traditional coatings.

[0053] This achieves a surface resistivity of ≤10Ω·cm for electrode plate 4, meeting the requirements for electric field conductivity, and resistance to sulfuric acid concentration ≤80%, as well as resistance to Cl. - F - It has more than 3 times the corrosion resistance, Vickers hardness ≥2500HV, and significantly enhanced resistance to particle erosion and wear.

[0054] Because the gap between the fixed electrode plates 4 is prone to scale formation due to residual salt or dust accumulation caused by droplet evaporation, it leads to airflow deviation.

[0055] By cooperating with the slot 21 of the support rod 2 and the guide slot 31 of the adjusting rod 3, the electrode plate 4 can be dynamically tilted by ±15°. The power component (electric push rod 34) drives the adjusting rod 3 to slide, causing the electrode plate 4 to tilt around the support rod 2 as the axis, changing the shape of the airflow channel and disrupting the stable conditions for scale formation.

[0056] This allows the inclined structure to disrupt the liquid film boundary layer separation, reduce salt deposition in localized dry areas, dynamically disturb the airflow path, prevent dust from accumulating in fixed gaps, reduce scaling by 70%, and reduce cleaning frequency to 1 / 3 of the original.

[0057] Fixed spray systems cannot thoroughly clean complex scale formations, leaving blind spots.

[0058] The spray head 5 is positioned directly above the connection between the electrode plate 4 and the support rod 2, directly covering the area at the base of the electrode plate 4 where scaling is likely to occur. The power unit and the spray head 5 are linked periodically, with the tilt angle synchronized with the spraying action. Every 10 seconds of spraying, the electrode plate 4 tilts by 5°, causing the droplets to flow faster along the tilted surface, flushing out dead corners. The tilt angle is also switched cyclically within ±15° to achieve multi-angle cleaning.

[0059] This increases the cleaning coverage from 60% in traditional solutions to 100%, reduces water consumption per spray by 30%, significantly saves water, and removes stubborn scale without manual intervention.

[0060] Since the fixed electrode plate 4 cannot adjust its tilt angle according to the humidity of the flue gas and the concentration of dust, it is easy to cause electric field disturbance.

[0061] The power unit is remotely adjusted via a PLC controller, supporting multiple operating modes. This embodiment is in manual mode, with the tilt angle controlled by on-site buttons; in other embodiments, an automatic mode can also be used, such as dynamically adjusting the tilt angle based on the flue gas humidity sensor signal.

[0062] To achieve the air intake and exhaust functions, the frame 1 is further described. The narrow side of the frame 1 facing the electrode plate 4 is closed, and the wide side of the frame 1 facing the electrode plate 4 is open. The open side of the frame 1 is the air intake 11, and the open side is the air outlet 12. The frame 1 is a welded frame of 316L stainless steel or titanium alloy, and the surface is coated with an epoxy glass flake anti-corrosion layer 13.

[0063] To meet dynamic adjustment requirements, the inner side of the support rod 2 is provided with several slots 21, and a first rotating shaft 22 protrudes outward from the lower side of the electrode plate. The first rotating shaft 22 is inserted into the slots 21 to achieve a rotatable connection. The support rod 2 is a solid titanium alloy cylinder, and several slots 21 with a depth of 5-8mm are equally spaced along the axial direction of the support rod 2. The width of the slots 21 is slightly larger than the diameter of the first rotating shaft 22, and the spacing between the slots 21 is consistent with the spacing of the electrode plates 4.

[0064] As a further improvement, a first rotating shaft 22 with a diameter of Φ10~15mm is welded to the lower side of the electrode plate 4, and the first rotating shaft 22 is perpendicular to the plane of the electrode plate 4.

[0065] A corrosion-resistant bearing 23 is installed in the slot 21. After the first rotating shaft 22 is inserted into the slot 21, it is inserted and fixed in the corrosion-resistant bearing 23.

[0066] Equidistant slots 21 are opened on the inner side of the support rod 2, with a depth of 5~8mm and a width slightly larger than the diameter of the first rotating shaft 22, so that the first rotating shaft 22 can rotate axially around the axis within the slots 21, forming a rotational kinematic pair.

[0067] The spacing of the slots 21 is strictly matched with the spacing of the electrode plates 4, which is 30~48mm, to ensure that each electrode plate 4 can be adjusted independently without interference.

[0068] The limiting effect of the slot 21 controls the tilt angle of the electrode plate 4 within a safe range (±15°), avoiding excessive tilting that could lead to airflow turbulence and mechanical interference.

[0069] In addition, sulfuric acid mist (pH 1-3) and Cl- are present in the wet electrostatic precipitator for a long time. -Ions and particles can cause pitting corrosion, stress corrosion, and fatigue fracture in traditional carbon steel or ordinary stainless steel support rods.

[0070] Therefore, titanium alloy support rod 2 was selected, using TA2 industrial pure titanium, which is resistant to sulfuric acid concentrations up to 50% (≤80℃) and Cl. - Its corrosion resistance far exceeds that of 316L stainless steel, with a pitting potential increased by more than 0.3V. Its density is 4.5 g / cm³, only 60% of that of 316L stainless steel, reducing structural weight and lowering drive power requirements.

[0071] The corrosion-resistant bearing 23 is made of ceramic (Si3N4) or Hastelloy (C-276), and its acid and alkali resistance (pH 1~14) and wear resistance (friction coefficient <0.1) are significantly better than those of the traditional chromium steel bearing 23. The surface of the bearing 23 is coated with PTFE or diamond-like carbon (DLC) coating to further reduce frictional resistance and prevent jamming.

[0072] To ensure structural stability, the electrode plate 4 must withstand the impact force of airflow (≥3m / s), the scouring force of droplets, and its own weight (5~10kg per piece) when dynamically tilted. The connection between the support rod 2 and the rotating shaft is the key load-bearing point.

[0073] The first rotating shaft 22 is a titanium alloy rotating shaft with a size of Φ10-15mm (tensile strength ≥550MPa) that matches the groove 21 with a depth of 5-8mm, ensuring that the rotating shaft has sufficient shear and bending strength after insertion.

[0074] To achieve a stable connection during dynamic tilting, a guide groove 31 is vertically provided on the side of the adjusting rod 3, and a second rotating shaft 35 is provided protruding outward on the upper side of the electrode plate. The second rotating shaft 35 is inserted into the guide groove 31, so that when the power component controls the adjusting rod 3 to drive the electrode plate 4 to deflect and move, the electrode plate 4 can maintain the connection with the adjusting rod 3.

[0075] Traditional fixed electrode plates 4 cannot adjust the tilt angle, while some dynamic adjustment structures use hinges or flexible connections, which have problems such as loose connections and uneven tilt angles, resulting in airflow turbulence or electric field distortion.

[0076] An "I"-shaped guide groove 31 is milled on the side of the adjusting rod 3. The groove width is 2-3 mm larger than the diameter of the second rotating shaft 35, and the groove depth is 10-15 mm. This ensures that the rotating shaft can withstand radial force and limit axial displacement when sliding in the groove.

[0077] A second rotating shaft 35 is welded to the upper end of the electrode plate 4. The second rotating shaft 35 has a size of Φ12~18mm and is made of titanium alloy. Its head is machined into a ball head structure and is embedded in the guide groove 31 for fixation, allowing the second rotating shaft 35 to slide in the groove and maintain a stable connection.

[0078] The adjusting rod 3 is made of hollow aluminum alloy square tube, with a guide shaft 32 passing through the inside of the aluminum alloy square tube, and both ends are slidably installed on the slide rails 33 above the frame 1.

[0079] The power assembly includes an electric push rod 34 mounted on the top of the frame 1, the end of which is hinged to the end of the adjusting rod 3 via a universal coupling. The electrode plate 4 is tilted at an angle of ±15°.

[0080] The power component that drives the adjusting rod 3 to slide left and right drives the adjusting rod 3 to slide along the top guide rail of the frame 1 via the electric push rod 34, thereby driving the second rotating shaft 35 to move in the guide groove 31.

[0081] During movement, the electrode plate 4 rotates with the support rod 2 as the fulcrum, and the second rotating shaft 35 slides along the guide groove 31 to form a lever effect, thereby achieving dynamic tilt angle adjustment of ±15°.

[0082] The adjusting rod 3 is made of hollow aluminum alloy square tube 50×50×3mm, with an anodized film thickness of ≥20μm, which combines lightweight and corrosion resistance;

[0083] The second rotating shaft 35 is made of titanium alloy (TA2), with a tensile strength ≥550MPa and resistance to sulfuric acid concentration up to 50%.

[0084] The guide groove 31 is protected by spraying a polytetrafluoroethylene (PTFE) coating (thickness 50~100μm) inside the groove to reduce the coefficient of friction (<0.1) and prevent direct metal-to-metal contact wear.

[0085] It also includes placing several sets of corona lines 6 on the central axis of the gap between the two electrode plates 4, and the ion flow generated by the corona through the corona lines 6 enhances the particle charging.

[0086] The corona wire 6 is fixedly installed at the top inside the frame 1, and the corona wire 6 is fixedly installed at the bottom inside the frame 1.

[0087] It should also be emphasized that the electric actuator 34 is an IP67 protected electric actuator (thrust ≥ 5kN, stroke 300~500mm), with a built-in planetary reducer (reduction ratio 50:1) to ensure stable output torque;

[0088] The control method supports 0~10V analog input or Modbus protocol communication, and the tilt angle can be accurate to 0.1°, meeting the control requirements of PLC-linked sprinkler systems.

[0089] The push rod housing is made of 316L stainless steel, and the internal bearing 23 and lead screw are made of ceramic material (Si3N4), with a corrosion resistance life of ≥8 years.

[0090] The universal coupling adopts a cross shaft type universal coupling (material: titanium alloy + PTFE bushing), which allows the shaft misalignment angle to be ≤5°, effectively absorbing the installation error between the adjusting rod 3 and the push rod;

[0091] The two ends of the coupling are hinged to the adjusting rod 3 and the end of the push rod through keyways, so that there is no backlash when transmitting torque (backlash error <0.05°), ensuring the synchronicity of tilting action and repeatability of positioning accuracy.

[0092] To ensure the uniformity of the electric field, the corona line 6 must be located on the central axis of the gap between the electrode plates 4 to ensure uniform distribution of the ion flow and avoid local electric field being too strong or weak due to offset.

[0093] The corona wire 6 expands due to heat during operation (length change rate ≤ 0.1%). The upper end of the corona wire 6 is fixed to the top crossbeam of the frame 1 by an insulating porcelain sleeve.

However, under the premise that those skilled in the art understand the principle of the above utility model, the specific details of its power mechanism, power supply system and control system can be clearly understood. The control method in the application document is automatic control through a controller.
