Description

An anode module and its wet electrostatic precipitator Technical Field

[0001] This invention relates to the field of electrostatic precipitator technology, specifically to an anode module and its wet electrostatic precipitator. Background Technology

[0002] Electrostatic precipitators (ESPs) are widely used dust removal equipment, mainly divided into wet and dry types. Their basic principle is based on electrostatics: dust particles are charged, and then an electric field is used to attract these charged particles to the electrodes, thus achieving dust removal. The two types of ESPs differ significantly in their subsequent cleaning methods: wet ESPs use a cleaning solution to rinse the electrodes, removing accumulated dust. This method effectively prevents secondary dust re-entrainment, and the cleaning solution can be recycled or properly treated before discharge, resulting in less environmental pollution. Dry ESPs, on the other hand, use mechanical vibration, such as hammering, to detach dust from the electrodes, which is then collected and treated by a collection system. This method does not require water, but may cause some secondary dust re-entrainment. In wet ESPs, the anode module plays a crucial role. It is not only the main area for dust particle adsorption but also guides charged dust particles towards the anode plate through electrostatic action, causing them to adhere tightly to its surface and form a dust layer. This effectively separates the flue gas from the dust, ensuring high dust removal efficiency and effectiveness.

[0003] In existing technologies, although spray devices are widely used for cleaning the anode modules of wet electrostatic precipitators, this traditional cleaning method has limitations. Specifically, since spray devices are mostly arranged above the anode and cathode components, the water from the spray layer is often partially blocked when flowing through the cathode frame. This results in the spray liquid not evenly covering all areas of the anode module, especially the top and edges, creating cleaning dead zones and preventing comprehensive cleaning. This not only affects dust removal efficiency but may also lead to excessive dust and dirt accumulation on the anode module surface, further impacting the overall performance and operational stability of the electrostatic precipitator. Furthermore, when scale builds up on the inner wall of the anode tubes after prolonged operation, simple water rinsing is often insufficient to effectively remove this hard scale, especially when the scale layer is thick or hard. This significantly reduces the rinsing effect, potentially lowering the conductivity of the anode module, increasing energy consumption and operating costs, and even shortening the anode module's lifespan. Summary of the Invention

[0004] The purpose of this invention is to provide an anode module and its wet electrostatic precipitator, which solves the problem that the existing water spraying method is difficult to thoroughly and effectively clean the anode module, thus affecting the cleaning effect.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An anode module includes multiple alternating groups of first anode tubes and second anode tubes. The first anode tube group is formed by welding multiple first anode tubes sequentially, and the second anode tube group is formed by welding multiple second anode tubes sequentially. The second anode tubes are welded to adjacent first anode tubes.

[0007] As a further aspect of the present invention: the first anode tube and the second anode tube have the same structure, and their cross-sections are both honeycomb structures. An upper stabilizing plate and a lower stabilizing plate are welded together on the outer tube walls near both ends of several first anode tubes and several second anode tubes.

[0008] A wet electrostatic precipitator includes the anode module described above.

[0009] As a further embodiment of the present invention, it also includes a housing, cathode wires, a cathode frame, and a cleaning mechanism. The upper stabilizing plate, the lower stabilizing plate, and the cathode frame are all installed inside the housing, and the cathode frame is located above the anode module. Several cathode wires extend vertically into several first anode tubes and several second anode tubes, and the cathode wires are suspended on the cathode frame. The cleaning mechanism is configured correspondingly to the anode module.

[0010] The cleaning mechanism includes a U-shaped frame, a telescopic scraper, a water supply assembly, and a water drive mechanism. Several telescopic scrapers are respectively inserted into several first anode tubes and several second anode tubes. Several U-shaped frames are equidistantly installed at the bottom of the lower stabilizing plate. The telescopic scrapers are connected to the U-shaped frames through the water drive mechanism. The water drive mechanism is used to drive the telescopic scrapers to rotate circumferentially. The water supply assembly is used to deliver water to the water drive mechanism.

[0011] As a further aspect of the present invention: the housing includes a shell cover and a flow collector with an air inlet, the flow collector being fixedly installed on the top of the shell cover, the air inlet being located on the top of the flow collector and communicating with the flow collector.

[0012] As a further embodiment of the present invention: the water-driven mechanism includes a cylinder, an annular disk, a rotating component, blades, a rotating shaft, and a water guide pipe. The cylinder is installed on the upper surface of the horizontal part of the U-shaped frame. The annular disk is coaxially connected to the top of the cylinder. The rotating component is rotatably connected to the annular disk. The cylinder and the annular disk are connected through the water guide pipe. The rotating shaft is rotatably installed at the center inside the cylinder, and the top of the rotating shaft extends into the annular disk and is coaxially connected to the rotating component. A plurality of blades are arranged inside the cylinder and distributed circumferentially along the rotating shaft.

[0013] As a further embodiment of the present invention: the telescopic scraper includes a scraper, a housing, a partition, a slide tube, and a spring. The bottom end of the housing is connected to the top end of the rotating component. The partition is fixedly installed inside the housing and divides the inner cavity of the housing into a sliding cavity and a water storage cavity in sequence. The scraper has a hollow internal structure and is slidably inserted into the sliding cavity. Multiple slide tubes are connected to the inner cavity of the scraper and slide through the partition. The spring is sleeved on the slide tube and installed inside the sliding cavity.

[0014] As a further aspect of the present invention: the water supply assembly includes a water supply pipe and branch pipes, multiple water supply pipes are arranged below the anode module, and one end of the water supply pipe penetrates the shell and extends outward, and several branch pipes are connected and arranged on the water supply pipe, and the end of the branch pipe away from the water supply pipe is connected to the corresponding cylinder.

[0015] As a further aspect of the present invention: the telescopic scraper further includes water spray holes and nozzles, a plurality of water spray holes are symmetrically arranged on both sides of the scraper and distributed along its length direction, and a plurality of nozzles are installed on the side of the housing away from the scraper, and the nozzles are in communication with the water storage cavity.

[0016] As a further embodiment of the present invention: the rotating component includes an annular plate, a water outlet, and a rotating ring with an annular water groove. The rotating ring is rotatably connected to an annular disk. The annular water groove is located at the bottom of the rotating ring and is connected to the annular disk. The water outlet is located at the top of the rotating ring. The annular water groove is connected to a water storage cavity through the water outlet. The annular plate is installed on the inner ring of the rotating ring and is coaxially connected to the rotating shaft.

[0017] The beneficial effects of this invention are:

[0018] 1. In this invention, an anode module is constructed by multiple alternating groups of first and second anode tubes. The first and second anode tubes have identical structures and honeycomb cross-sections. This design not only increases the surface area of ​​the anode module, improving dust removal efficiency, but also enhances its mechanical strength and stability through the honeycomb structure. Furthermore, each anode tube has an upper and lower stabilizing plate welded to its outer wall near both ends. This structure further strengthens the overall stability of the anode module, making it less prone to deformation or damage during use and thus extending its service life.

[0019] 2. In this invention, clean water is conveniently introduced into each water-driven mechanism through the water supply component. The power of the water flow facilitates the water-driven mechanism to drive the telescopic scraper to rotate circumferentially. The telescopic scraper can easily adapt to its extension and retraction, so that it can scrape against the inner walls of the first anode tube and the second anode tube when rotating circumferentially, which is convenient for cleaning hard scale. In addition, the water-driven mechanism can also introduce water into the telescopic scraper and spray it out, so that it can achieve spraying during the circumferential rotation, thereby facilitating comprehensive spray cleaning and effectively improving the cleaning effect.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] As shown in Figure 1, the present invention provides an anode module comprising multiple alternating sets of first anode tube groups 1 and second anode tube groups 2. The first anode tube group 1 is formed by sequentially welding multiple first anode tubes 101, and the second anode tube group 2 is formed by sequentially welding multiple second anode tubes 201, wherein the second anode tubes 201 are welded to adjacent first anode tubes 101.

[0035] It should be noted that this application does not limit the number of the first anode tube group 1, the second anode tube group 2, the first anode tube 101, and the second anode tube 201. The following only provides a specific number for reference: the first anode tube group 1 and the second anode tube group 2 are each set to 4 groups. Each first anode tube group 1 is composed of 8 first anode tubes 101 welded together, and each second anode tube group 2 is composed of 7 second anode tubes 201 welded together.

[0036] As shown in Figure 1, the first anode tube 101 and the second anode tube 201 have the same structure, and their cross-sections are both honeycomb structures. Several first anode tubes 101 and several second anode tubes 201 are welded together with an upper stabilizing plate 3 and a lower stabilizing plate 4 near the outer tube walls at both ends.

[0037] It should be noted that the honeycomb structure not only increases the surface area of ​​the first anode tube 101 and the second anode tube 201, improving dust removal efficiency, but also helps to improve mechanical strength and stability. The upper stabilizing plate 3 and the lower stabilizing plate 4 further improve the overall structural stability of the anode module, making it less prone to deformation or damage, which is beneficial to improving the service life of the anode module.

[0038] As shown in Figures 2-6, the present invention provides a wet electrostatic precipitator, including the aforementioned anode module, a housing 5, cathode wires 6, a cathode frame 7, and a cleaning mechanism 8. The upper stabilizing plate 3, the lower stabilizing plate 4, and the cathode frame 7 are all installed within the housing 5, with the cathode frame 7 positioned above the anode module. An atomizing flushing system (not shown in the figures) is also provided above the cathode frame 7. The atomizing flushing system is a mature technology for wet electrostatic precipitators and will not be elaborated upon here. Several cathode wires 6 extend vertically into several first anode tubes 101 and several second anode tubes 201, respectively. 6 is suspended on the cathode frame 7, and the cleaning mechanism 8 is set correspondingly to the anode module; the cleaning mechanism 8 includes a U-shaped frame 81, a telescopic scraper 82, a water supply component 83 and a water drive mechanism 84. Several telescopic scrapers 82 are respectively inserted into several first anode tubes 101 and several second anode tubes 201. Several U-shaped frames 81 are equidistantly installed at the bottom of the lower stabilizing plate 4. The telescopic scraper 82 is connected to the U-shaped frame 81 through the water drive mechanism 84. The water drive mechanism 84 is used to drive the telescopic scraper 82 to rotate circumferentially. The water supply component 83 is used to transport water to the water drive mechanism 84.

[0039] It should be noted that when it is necessary to clean the inner walls of the first anode tube 101 and the second anode tube 201, the water supply component 83 can be used to deliver clean water to the water drive mechanism 84. The water drive mechanism 84 can use the power generated by the water flow to drive the telescopic scraper 82 to rotate circumferentially. The telescopic scraper 82 can adaptively retract during the circumferential rotation, so that one side can always be in contact with the inner wall of the first anode tube 101 and / or the second anode tube 201, thereby effectively scraping off the hard scale attached to the inner wall. At the same time, the water drive mechanism 84 can also introduce water into the telescopic scraper 82, so that the telescopic scraper 82 can be thoroughly sprayed and rinsed during the scraping of hard scale, which is conducive to further improving the cleaning effect.

[0040] As shown in Figures 2 and 3, the housing 5 includes a housing 51 and a shroud 53 with an air inlet 52. The shroud 53 is fixedly installed on the top of the housing 51, and the air inlet 52 is located on the top of the shroud 53 and is connected to the shroud 53.

[0041] It should be noted that the dust-laden gas enters through the inlet 52 and is drawn into the housing 51 by the collector hood 53. It first comes into contact with the atomizing flushing system (not shown in the figure) to wet and partially remove the dust particles in the gas. Then, the wetted dust-laden gas enters the anode module area inside the housing 51. The cathode wire 6 (as shown in Figure 6) discharges under the action of DC high voltage, ionizing the surrounding gas and charging the surface of the dust or mist droplets. Under the action of the electric field force, the charged particles move towards the first anode tube 101 and the second anode tube 201 (as shown in Figure 4) and are deposited on their inner walls. Then, the water generated by the spray is used to flush them. The waste liquid generated by the flushing is discharged through the bottom opening of the housing 51 to the external desulfurization tower or wastewater treatment system for further treatment.

[0042] As shown in Figures 2, 5 and 7, the water supply assembly 83 includes a water supply pipe 831 and branch pipes 832. Multiple water supply pipes 831 are arranged below the anode module, and one end of the water supply pipe 831 passes through the shell 5 and extends outward. Several branch pipes 832 are connected to the water supply pipe 831, and the end of the branch pipe 832 away from the water supply pipe 831 is connected to the corresponding cylinder 841.

[0043] It should be noted that in this embodiment, there are four water supply pipes 831. The water supply pipes 831 are used to transport clean water. The end of the water supply pipe 831 that extends into the housing 5 is a closed structure. The clean water entering the water supply pipe 831 is introduced into the corresponding cylinder 841 (as shown in Figure 8) through each branch pipe 832.

[0044] As shown in Figures 7-9, the water-driven mechanism 84 includes a cylinder 841, an annular disk 842, a rotating component 843, blades 844, a rotating shaft 845, and a water guide pipe 846. The cylinder 841 is installed on the upper surface of the horizontal part of the U-shaped frame 81. The annular disk 842 is coaxially connected to the top of the cylinder 841. The rotating component 843 is rotatably connected to the annular disk 842. The cylinder 841 and the annular disk 842 are connected through the water guide pipe 846. The rotating shaft 845 is rotatably installed at the center inside the cylinder 841, and the top of the rotating shaft 845 extends into the annular disk 842 and is coaxially connected to the rotating component 843. Multiple blades 844 are arranged inside the cylinder 841 and distributed circumferentially along the rotating shaft 845.

[0045] It should be noted that the rotating component 843 is rotatably connected to the annular disk 842 via a sealed bearing. The clean water injected into the cylinder 841 impacts the blades 844, thereby causing the rotating shaft 845 to drive the rotating component 843 to rotate synchronously. When the rotating component 843 rotates, it drives the telescopic scraper 82 connected to it to rotate circumferentially. The water in the cylinder 841 can flow into the annular disk 842 through the water guide pipe 846. The annular disk 842 guides the water into the rotating component 843, and finally injects it into the telescopic scraper 82 for spraying, thereby improving the cleaning effect.

[0046] As shown in Figures 7 and 11, the telescopic scraper 82 includes a scraper 821, a housing 822, a partition 823, a slide tube 824, and a spring 825. The bottom end of the housing 822 is connected to the top end of the rotating component 843. The partition 823 is fixedly installed inside the housing 822 and divides the inner cavity of the housing 822 into a sliding cavity 8221 and a water storage cavity 8222 in sequence. The scraper 821 has a hollow structure inside and is slidably inserted into the sliding cavity 8221. Multiple slide tubes 824 are connected to the inner cavity of the scraper 821 and slide through the partition 823. The spring 825 is sleeved on the slide tube 824 and installed inside the sliding cavity 8221.

[0047] It should be noted that the end of the scraper 821 away from the housing 822 is tapered. When the scraper 821 touches the inner wall corner of the first anode tube 101 and / or the second anode tube 201, it is set to the initial state (as shown in Figure 6). During subsequent rotation, the scraper 821 will first be pressed and slide along the housing 822, compressing the spring 825. Then, the spring 825 drives the scraper 821 to self-reset. This cycle repeats. During the circumferential rotation of the telescopic scraper 82, the scraper 821 always adheres to the inner wall of the first anode tube 101 and / or the second anode tube 201, thus facilitating the removal of hard scale. A sealing ring is provided at the connection between the slide tube 824 and the partition 823 to prevent water in the water storage chamber 8222 from entering the slide chamber 8221. The water storage chamber 8222 is connected to the inner cavity of the rotating component 843, allowing water in the inner cavity of the rotating component 843 to be introduced into the water storage chamber 8222 and then enter the scraper 821 through the slide tube 824.

[0048] As shown in Figures 7 and 10-11, the telescopic scraper 82 also includes water spray holes 826 and nozzles 827. Several water spray holes 826 are symmetrically arranged on both sides of the scraper 821 and distributed along its length. Several nozzles 827 are installed on the side of the housing 822 away from the scraper 821, and the nozzles 827 are connected to the water storage chamber 8222.

[0049] It should be noted that during the adaptive extension and retraction of the scraper 821 along the housing 822, the water spray hole 826 will never enter the housing 822. The water spray hole 826 facilitates the comprehensive rinsing of the inner wall of the first anode tube 101 and / or the second anode tube 201, further improving the cleaning effect. Some of the water in the water storage cavity 8222 enters the nozzle 827 and is sprayed out, thereby facilitating the comprehensive rinsing and cleaning of the cathode wire 6 (as shown in Figure 6).

[0050] As shown in Figures 9 and 11, the rotating component 843 includes an annular plate 8431, a water outlet 8432, and a rotating ring 8434 with an annular water groove 8433. The rotating ring 8434 is rotatably connected to the annular disk 842. The annular water groove 8433 is located at the bottom of the rotating ring 8434 and is connected to the annular disk 842. The water outlet 8432 is located at the top of the rotating ring 8434. The annular water groove 8433 is connected to the water storage chamber 8222 through the water outlet 8432. The annular plate 8431 is installed on the inner ring of the rotating ring 8434 and is coaxially connected to the rotating shaft 845.

[0051] It should be noted that after the water in the cylinder 841 flows into the annular disk 842 through the water guide pipe 846, when the annular disk 842 is full of water, as the water is continuously replenished, the water in the annular disk 842 will enter the annular water tank 8433, and then be introduced into the water storage chamber 8222 through the water outlet 8432. When the rotating shaft 845 rotates, it drives the annular plate 8431 to rotate synchronously. When the annular plate 8431 rotates, it drives the rotating ring 8434 to rotate. This not only allows the rotating ring 8434 to rotate normally along the annular disk 842, but also ensures that the water in the annular disk 842 can enter the water storage chamber 8222 through the rotating part 843.

[0052] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
