Description

Technical Field

[0001] The utility model relates to the technical field of electric precipitators, in particular to a wet electric precipitator. Background Art

[0002] At present, the state controls the smoke emission standards for coal-burning, metallurgical and other industries at 20-30 / Nm2. In the next few years, the state will further improve the smoke emission standards, which will undoubtedly put forward higher requirements on the dust removal efficiency and reliability of dust removal equipment.

[0003] Electrostatic precipitator is a common dust removal equipment, which is divided into wet electrostatic precipitator and dry electrostatic precipitator. The dust removal mechanism of wet electrostatic precipitator and dry electrostatic precipitator is the same. They both adsorb dust through electrostatic effect. The difference is that the cleaning method after collecting dust is different. The wet electrostatic precipitator uses cleaning fluid to flush the electrode to remove the collected dust, while the latter uses hammering and vibration to make the dust separate from the electrode. The wet electrostatic precipitator collects particulate matter without being limited by resistivity, and has a high efficiency in removing inhalable dust. It can also adsorb gas and remove sulfuric acid trioxide mist and heavy metals in flue gas. Therefore, the most effective equipment currently recognized for treating flue gas after desulfurization is the wet electrostatic precipitator.

[0004] The main components of a common wet electrostatic precipitator are a suspension beam, a spray device, and an anode assembly and a cathode assembly mounted on the suspension beam. In a traditional wet electrostatic precipitator, the spray device is designed separately, which not only takes up space, but also increases the weight of the equipment and the manufacturing cost of the equipment. Utility Model Content

[0005] The utility model provides a wet electrostatic precipitator, which solves the above-mentioned technical problems.

[0006] The utility model solves the above-mentioned technical problems as follows:

[0007] A wet electrostatic precipitator comprises a joint, a shell, an electrode assembly and a sleeve, wherein the electrode assembly is installed inside the shell, a through hole is opened on the shell, a baffle is installed inside the shell at the through hole through a torsion spring, a sleeve is installed on the shell at the outside of the through hole, a joint is installed in the sleeve, a pressure plate is provided on the joint, the joint is elastically installed in the sleeve through the pressure plate and a spring, and a nozzle is installed at the end of the sleeve.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the electrode assembly includes a cathode assembly and an anode assembly, and the angle between the cathode assembly and the anode assembly is ninety degrees.

[0010] The beneficial effects of adopting the above further scheme are:

[0011] Uniform electric field distribution: The ninety-degree angle between the cathode and anode assemblies helps to form a uniform and stable electric field. This uniform distribution of the electric field is very important because it determines the efficiency with which dust particles are attracted and captured. The uniform electric field ensures that dust is effectively captured throughout the electrode area, thereby improving dust removal efficiency.

[0012] Enhanced electric field strength: The ninety-degree angle design increases the strength of the electric field. When the angle between the electrode components is right angles, the strength of the electric field is higher. This means that the electric field can act more strongly on dust particles in the air, making them easier to attract and capture.

[0013] Reduce corona discharge: The 90-degree angle between the electrodes also helps reduce the occurrence of corona discharge. Corona discharge can cause energy waste and equipment damage, so by optimizing the electrode angle, this phenomenon can be reduced and the stability and durability of the dust collector can be improved.

[0014] Avoid gaps or overlaps: The 90-degree angle design between the cathode assembly and the anode assembly can effectively avoid gaps or overlaps. Gaps may cause discontinuity in the electric field, thus affecting the dust removal effect. On the other hand, overlaps may cause areas where the electric field is too strong or too weak, which will also affect the performance of the dust collector. By maintaining a 90-degree angle, these problems can be avoided and the continuity and uniformity of the electric field can be ensured.

[0015] Simplified structural design: The 90-degree angle design also makes the installation and maintenance of the electrode assembly easier. Engineers and technicians can more easily design and adjust the layout of the electrodes without worrying about complex angles and positional relationships.

[0016] Furthermore, one end of the connector where the nozzle is installed is conical, so that the connector can easily push open the baffle and extend into the housing.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] Push through the baffle easily: The conical design of the connector end has a smaller tip, making it easier to pass through the baffle. When the connector is pushed, the conical tip is able to pass through the baffle hole more smoothly and push the connector into the housing. This simplifies the operation process and reduces potential resistance.

[0019] Reduced fender wear: The tapered connector end reduces friction and wear when contacting the fender. Compared to a flat connector end, the tapered end reduces the contact surface area, reducing the friction between the fender and the connector during the push process. This helps extend the service life of the fender and connector.

[0020] Ensure stable advancement: The tapered end design ensures that the connector remains stable during the pushing process. The geometry of the tapered end allows the connector to push forward and easily pass through the baffle hole. This helps operators push the connector into the housing more easily, ensuring the normal operation of the equipment.

[0021] Precise Positioning: The tapered design not only allows for easy passage through the baffle, but also helps to accurately position the connector. Once the tapered end passes through the baffle, the connector can be accurately positioned in the desired position, ensuring that the sprinkler or other components are correctly installed in the desired position, thereby improving the efficiency and performance of the equipment.

[0022] Simplified maintenance and cleaning: The conical design of the connector end can simplify the maintenance and cleaning process of the equipment. When the nozzle or other parts need to be replaced or cleaned, the design of the conical end point makes the operation easier and faster. The operator can easily push the connector to remove it from the baffle and perform the required maintenance work.

[0023] Furthermore, the through holes are distributed in a rectangular array on the housing.

[0024] The beneficial effects of adopting the above further scheme are:

[0025] Increased processing surface area: The rectangular array distribution design of the through holes can give the dust collector a larger processing surface area. This means that more air will contact the electrode assembly when flowing through the through holes, thereby improving the collection efficiency of the dust collector.

[0026] Uniform air flow: The through holes in a rectangular array help achieve more uniform air flow. This avoids poor air flow or dead corners in some areas, ensuring that all areas receive good dust removal effects.

[0027] Improve dust removal efficiency: The design of rectangular array distribution of through holes can make the dust collector have more through holes under the same size, thereby increasing the chance of dust particles being captured, thereby improving dust removal efficiency.

[0028] Reduce air resistance: The rectangular array of through-holes can effectively reduce the resistance of air in the through-holes. This helps reduce energy consumption and improves the operating efficiency of the dust collector.

[0029] Optimized fluid dynamics: The rectangular array of through-holes takes fluid dynamics into consideration, making the air flow through the through-holes smoother and more efficient. This helps improve the overall performance and stability of the dust collector.

[0030] Furthermore, the connectors are symmetrically distributed above the electrode assembly.

[0031] The beneficial effects of adopting the above further scheme are:

[0032] Uniform water spray coverage: The design of the joints being symmetrically distributed over the electrode assembly ensures that the water spray system covers the entire electrode area. This means that the water spray is evenly distributed over all electrodes, effectively wetting and cleaning the electrode surface. This helps prevent dust particles from accumulating on the electrodes and improves dust removal efficiency.

[0033] Increased treatment range: Symmetrical distribution of joints allows the water spray to cover a wider range, covering the entire surface of the electrode assembly. This helps ensure that all electrodes can be cleaned promptly and adequately, thereby maintaining efficient operation of the dust collector.

[0034] Reduce dead angles and loopholes: The symmetrical distribution design of the joints can reduce dead angles and loopholes in the electrode area. This means that the water spray system can better cover all electrode surfaces, prevent dust from accumulating in uncleaned areas, and improve the overall cleaning effect of the dust collector.

[0035] Improved cleaning uniformity: With symmetrical distribution of joints, the water spray system ensures uniform cleaning across the entire electrode assembly. This helps avoid over-cleaning or under-cleaning of some areas, thereby improving the stability and efficiency of the dust collector.

[0036] Reduced maintenance costs: The symmetrical design of the joints can reduce the frequency of maintenance and cleaning. Since the water spray system can more completely cover the electrode surface, the number of maintenance and cleaning cycles required may be reduced, reducing maintenance costs and downtime.

[0037] The beneficial effects of the utility model are:

[0038] Optimization of electrode assembly layout: The design of the electrode assembly uses a cathode assembly and an anode assembly with a 90-degree angle between them. This layout ensures a uniform distribution of the electric field, thereby enhancing the efficiency of dust particle capture. The angle design between the cathode and anode may help to generate a stronger electric field and improve the dust removal effect.

[0039] Through-hole layout design: The housing is provided with through-holes arranged in a rectangular array. This design increases the surface area for the electric field to act on, allowing the wet ESP to capture dust particles more effectively. The through-hole layout may also help increase air flow, improving the collector's adsorption efficiency.

[0040] Baffle and sleeve design: A baffle is installed at the through hole inside the shell through a torsion spring, and a sleeve is installed on the outside of the shell. This design can effectively prevent external contaminants from entering the internal system of the dust collector and keep the electrode assembly clean. The baffle and sleeve design may also help reduce the impact of impurities on dust collector performance and extend the service life of the equipment.

[0041] Joint and pressure plate design: The joints are symmetrically located above the electrode assembly and are provided with pressure plates. The joints are elastically mounted inside the sleeve through the pressure plate and springs. This design ensures a secure fixation of the joints to prevent them from loosening or shifting during operation. Stable installation of the joints may help maintain stable performance of the equipment and reduce maintenance requirements.

[0042] Nozzle design: A nozzle is installed at the end of the sleeve, and one end of the joint is tapered. This design allows the water spray to enter the dust collector more accurately and ensures uniform distribution of the water flow. The tapered joint design may help optimize the speed and direction of the water flow, thereby improving the cleaning effect of the dust collector.

[0054] Embodiment 1

[0055] A wet electrostatic precipitator comprises a joint 3, a shell 4, an electrode assembly 5 and a sleeve 7, wherein an electrode assembly 5 is installed inside the shell 4, wherein the electrode assembly 5 comprises a cathode assembly and an anode assembly, and the angle between the cathode assembly and the anode assembly is ninety degrees, and the ninety-degree angle between the cathode assembly and the anode assembly helps to form a uniform and stable electric field. The uniform distribution of the electric field is very important because it determines the efficiency of dust particles being attracted and captured. The uniform electric field can ensure that the dust is effectively captured in the entire electrode area, thereby improving the dust removal efficiency. The ninety-degree angle design increases the intensity of the electric field. When the angle between the electrode assemblies 5 is a right angle, the intensity of the electric field is higher. This means that the electric field can act more strongly on the dust particles in the air, making them easier to be attracted and captured. The ninety-degree angle between the electrodes also helps to reduce the occurrence of corona discharge. Corona discharge may cause energy waste and equipment damage, so by optimizing the electrode angle, the occurrence of this phenomenon can be reduced, and the stability and durability of the precipitator can be improved. The ninety-degree angle design between the cathode assembly and the anode assembly can effectively avoid gaps or overlaps. Gaps may cause discontinuity in the electric field, thereby affecting the dust removal effect. On the other hand, overlaps may cause areas where the electric field is too strong or too weak, which will also affect the performance of the dust collector. By maintaining a ninety-degree angle, these problems can be avoided and the continuity and uniformity of the electric field can be ensured. The design of the ninety-degree angle also makes the installation and maintenance of the electrode assembly 5 simpler. Engineers and technicians can more easily design and adjust the layout of the electrodes without worrying about complex angles and positional relationships. A through hole 9 is provided on the housing 4, and the through holes 9 are distributed in a rectangular array on the housing 4. The design of the rectangular array distribution of the through holes 9 can make the dust collector have a larger processing surface area. This means that more air will contact the electrode assembly 5 when flowing through the through hole 9, thereby improving the capture efficiency of the dust collector. The through holes 9 distributed in a rectangular array help to achieve more uniform air flow. This can avoid poor air flow or dead corners in some areas and ensure that all areas can receive good dust removal effects. The rectangular array distribution design of the through holes 9 allows the dust collector to have more through holes 9 at the same size, thereby increasing the chances of dust particles being captured, thereby improving the dust removal efficiency. The rectangular array distribution design of the through holes 9 can effectively reduce the resistance of the air in the through holes 9. This helps to reduce energy consumption and improve the operating efficiency of the dust collector. The rectangular array distribution design of the through holes 9 takes into account fluid dynamics factors, making the flow of air in the through holes 9 smoother and more efficient. This helps to improve the overall performance and stability of the dust collector. The interior of the shell 4 is located at the through hole 9 and a baffle 6 is installed through a torsion spring. The shell 4 is located on the outside of the through hole 9 and a sleeve 7 is installed. A joint 3 is installed in the sleeve 7. The joint 3 is symmetrically distributed above the electrode assembly 5. The design of the joint 3 being symmetrically distributed above the electrode assembly 5 can ensure that the water spray system covers the entire electrode area.This means that the water spray is evenly distributed on all electrodes, effectively wetting and cleaning the electrode surface. This helps prevent dust particles from accumulating on the electrodes and improves the dust removal efficiency. The symmetrical distribution of joints 3 allows the water spray to cover a wider range, covering the entire surface of the electrode assembly 5. This helps to ensure that all electrodes can be cleaned promptly and adequately, thereby maintaining the efficient operation of the dust collector. The symmetrical distribution design of joints 3 can reduce dead corners and loopholes in the electrode area. This means that the water spray system can better cover all electrode surfaces, prevent dust from accumulating in uncleaned areas, and improve the overall cleaning effect of the dust collector. Through the symmetrical distribution of joints 3, the water spray system can ensure a uniform cleaning effect on the entire electrode assembly 5. This helps to avoid over-cleaning or under-cleaning of some areas, thereby improving the stability and efficiency of the dust collector. The symmetrical distribution design of joints 3 can reduce the frequency of maintenance and cleaning. Since the water spray system can cover the electrode surface more comprehensively, the number of maintenance times and cleaning cycles required may be reduced, reducing maintenance costs and downtime. A pressure plate 2 is provided on the joint 3. The joint 3 is elastically installed in the sleeve 7 through the pressure plate 2 and the spring 1, and a nozzle 8 is installed at the end of the sleeve 7. The end of the joint 3 where the nozzle 8 is installed is conical, which makes it easier for the joint 3 to push the baffle 6 and extend into the housing 4. The conical end of the joint 3 has a smaller end point, making it easier to pass through the baffle 6. When the joint 3 is pushed, the conical end point can pass through the baffle 6 hole more smoothly and push the joint 3 into the housing 4. This simplifies the operation process and reduces potential resistance. The conical end of the joint 3 can reduce friction and wear when contacting the baffle 6. Compared with the flat end of the joint 3, the conical end point reduces the contact surface area and reduces the friction between the baffle 6 and the joint 3 during the pushing process. This helps to extend the service life of the baffle 6 and the joint 3. The conical end point design can ensure that the joint 3 remains stable during the pushing process. The geometry of the tapered end point allows the connector 3 to be pushed forward and to pass easily through the baffle 6 hole. This helps the operator to push the connector 3 into the housing 4 more easily to ensure the normal operation of the equipment. The tapered design not only allows easy passage through the baffle 6, but also helps to accurately position the connector 3. Once the tapered end point passes through the baffle 6, the connector 3 can be accurately positioned in the desired position to ensure that the nozzle 8 or other components are correctly installed in the desired position, thereby improving the efficiency and performance of the equipment. The tapered end of the connector 3 can simplify the maintenance and cleaning process of the equipment. When the nozzle 8 or other components need to be replaced or cleaned, the design of the tapered end point makes the operation more convenient and quick. The operator can easily push the connector 3, remove it from the baffle 6, and perform the required maintenance work.

[0056] A wet electrostatic precipitator based on Example 1 is used:

[0057] Optimization of the layout of the electrode assembly 5: The design of the electrode assembly 5 uses a cathode assembly and an anode assembly, and the angle between them is 90 degrees. This layout ensures a uniform distribution of the electric field, thereby enhancing the efficiency of dust particle capture. The angle design between the cathode and the anode may help to generate a stronger electric field and improve the dust removal effect.

[0058] Through hole 9 layout design: Through holes 9 are provided on the housing 4, and these through holes 9 are distributed in a rectangular array. This design increases the surface area for the electric field to act on, so that the wet electrostatic precipitator can capture dust particles more effectively. The layout of the through holes 9 may also help increase air flow and improve the adsorption efficiency of the precipitator.

[0059] Design of baffle 6 and sleeve 7: baffle 6 is installed at the through hole 9 inside the housing 4 through a torsion spring, and sleeve 7 is installed on the outside of the housing 4. This design can effectively prevent external pollutants from entering the internal system of the dust collector and keep the electrode assembly 5 clean. The design of baffle 6 and sleeve 7 may also help reduce the impact of impurities on the performance of the dust collector and extend the service life of the equipment.

[0060] Design of connector 3 and pressure plate 2: connector 3 is symmetrically distributed above electrode assembly 5 and is provided with pressure plate 2. Connector 3 is elastically mounted inside sleeve 7 through pressure plate 2 and spring 1. This design ensures the stable fixation of connector 3 to prevent it from loosening or shifting during operation. The stable installation of connector 3 may help maintain the performance of the equipment and reduce maintenance requirements.

[0061] Nozzle 8 design: The end of the sleeve 7 is equipped with a nozzle 8, and one end of the joint 3 is tapered. This design allows the water to enter the dust collector more accurately and ensures uniform distribution of the water flow.
