Description

Technical Field

[0001] The utility model belongs to the field of environmental protection, relates to the technical field of electrostatic precipitators, and specifically is an anode plate structure of an electrostatic precipitator. Background Technique

[0002] Dust collectors are essential supporting equipment for thermal power plants, building materials industries, smelting industries, and various industrial furnaces. Its function is to remove particulate dust in the flue gas discharged from boilers, thereby greatly reducing the amount of dust discharged into the atmosphere. This is an important environmental protection equipment for improving environmental pollution and air quality. Electrostatic precipitators are widely used in industrial fields such as electric power, building materials, non-ferrous metallurgy, and chemical industry due to their characteristics of large flue gas treatment volume, high dust removal efficiency, low equipment resistance, low energy consumption, ability to handle high-temperature dust, low operating costs, and convenient management.

[0003] The anode plate is one of the most critical components of an electrostatic precipitator. Its main function is to adsorb most of the ash in the electric field, so as to facilitate subsequent collection and achieve the effect of dust removal.

[0004] Currently, electrostatic precipitators usually adopt a C-type anode plate structure. As Figure 1 shown, it mainly includes an anode plate body 1 formed integrally, a bending part 101, and a connecting part 102. The bending parts 101 are arranged on both sides of the anode plate body 1 and are connected to the anode plate body 1 through the connecting part 102. It can be seen from the figure that the connecting part 102 is usually set as an inclined bending edge to complete the connection. The area covered by the inclined bending edge under the same size is relatively limited, and it is difficult to meet the requirement of intercepting more dust.

[0005] Moreover, in the prior art, the installation of the anode plate structure usually requires connecting bolts and vibrating rods at the upper and lower positions respectively. During installation, bolts are usually directly passed through the suspension holes 103 of the anode plate body 1 for fixation. However, due to the thickness of the anode plate body 1, when an external force (such as when wind sucks in dust) acts on the surface of the anode plate body 1, the suspension holes 103 connected to the connecting bolts and vibrating rods will be worn more and more seriously, and then the position where the suspension holes 103 are located may become a notch, seriously affecting the service life.

[0006] Therefore, an anode plate structure of an electrostatic precipitator is needed to solve the above problems. Content of the Utility Model

[0007] The utility model aims to solve at least one of the technical problems existing in the prior art; to this end, the utility model proposes an anode plate structure of an electrostatic precipitator, so as to further increase the dust accumulation area of the anode plate structure under the condition of the same size, thereby improving the interception and adsorption effect of dust, and improving the wear of the anode plate hanging hole, so as to extend the service life of the device. The utility model arranges a tubular rivet part to strengthen the strength of the hanging hole at the connection between the anode plate body and the bolt, and arranges a connecting plate connected to the rapping rod, and makes the thickness of the connecting plate greater than the thickness of the anode plate body, so that when the rapping rod is running, the connecting plate is used as the main force-bearing component, and the strength of the connecting plate itself can effectively meet the operation requirements of the rapping rod, thereby extending the service life of the device.

[0008] To achieve the above-mentioned object, the first aspect of the utility model provides an anode plate structure of an electrostatic precipitator, comprising an anode plate body, a tubular rivet member and a connecting plate;

[0013] The connecting plate is fixedly mounted on the lower part of the anode plate body, and the thickness of the connecting plate is greater than the thickness of the anode plate body, and is used for connecting with the rapping rod.

[0014] Furthermore, the anode plate body, the recessed portion and the bent portion are integrally formed.

[0015] Furthermore, the recessed portion is configured as a "凵"-shaped structure, and both side walls of the recessed portion gradually approach each other along the center line direction from the outside to the inside.

[0016] Furthermore, the two side walls of the recessed portion are arranged as arc-shaped bent edges that bulge along the center line direction of the recessed portion.

[0017] Furthermore, at least two tubular rivet members are provided on the upper part of the anode plate body.

[0018] Furthermore, the thickness of the anode plate body is 0.6 mm-2 mm, and the thickness of the connecting plate is 5 mm-8 mm.

[0019] Further, the anode plate body and the connecting plate are fixedly connected by the tubular rivet or by welding.

[0020] Further, the maximum horizontal distance D between the bending part and the concave part is 55 mm - 65 mm.

[0021] Further, the bending part includes a first bending edge, a second bending edge and a third bending edge which are connected in sequence and surround to form a rectangular open cavity;

[0022] The first bending edge is connected to the concave part.

[0023] Further, the length of the third bending edge is less than the length of the first bending edge.

[0024] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0025] By providing a tubular rivet and making the tubular rivet penetrate through the upper part of the anode plate body to form a suspension hole, the strength of the suspension hole at the connection between the anode plate body and the bolt can be effectively enhanced. Further, by providing a connecting plate connected to the vibration rod and fixedly connecting the connecting plate to the anode plate body and making its thickness greater than that of the anode plate body, when the vibration rod operates and the connecting plate serves as the main stress component, the strength of the connecting plate itself can effectively meet the requirements of the operation of the vibration rod, so as to achieve the purpose of extending the service life of the device.

[0034] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] Please refer to Figure 2 and Figure 3 As shown, the first aspect embodiment of the present utility model provides an anode plate structure of an electrostatic precipitator, including an anode plate body 1, a tubular rivet part 2, and a connecting plate 3.

[0036] Among them, on both sides of the anode plate body 1, there are symmetrically formed bending parts 11 that bulge outward. The bending part 11 forms a windproof groove to effectively prevent the secondary flying of the dust shaken off during the operation of the rapping rod.

[0037] At the connection between the anode plate body 1 and the bending part 11, there is a concave part 12 that deviates from the bulging direction of the bending part 11. By means of the concave part 12, the existing connection method using an inclined bending edge is replaced. By means of the concave method, the contact area between this part and the dust can be increased under the same size, thereby improving the interception and adsorption effect on the dust.

[0038] In this embodiment, the tubular rivet part 2 is penetrated through the upper part of the anode plate body 1 to form a hanging hole 13. By using the hollow through hole of the tubular rivet part 2 as the hanging hole 13, when it is necessary to fix the upper part of the anode plate body 1 with bolts, the bolts will contact the inner wall of the tubular rivet part 2 instead of directly acting on the anode plate body 1. And because the tubular rivet part 2 has the characteristics of wear resistance and high hardness, when the anode plate body 1 swings under the influence of external forces and causes friction between the bolts and the hanging hole 13, the anode plate body 1 will not be directly worn. Therefore, the service life of this device can be effectively extended.

[0039] The upper part of the anode plate body 1 is also provided with reinforcing ribs 14, which are located in the same vertical plane as the tubular rivet member 2. The reinforcing ribs 14 are provided to enhance the strength of the hanging hole 13 located at the upper part of the anode plate body 1, thereby extending the service life of the device.

[0040] In addition, the connecting plate 3 is fixedly installed at the lower part of the anode plate body 1, and the thickness of the connecting plate 3 is greater than the thickness of the anode plate body 1, and is used to connect with the rapping rod. By using the connecting plate 3 as a connecting part to connect with the rapping rod, the stress formed when the rapping rod is in operation is mainly concentrated on the connecting plate 3. Since the thickness of the connecting plate 3 is greater than the thickness of the anode plate body 1, its own strength is also stronger than that of the anode plate body 1. Therefore, the force of the rapping rod acting on the anode plate body 1 is reduced by using the connecting plate 3 to further extend the service life of the device.

[0041] This patent sets a tubular rivet 2, and makes the tubular rivet 2 penetrate the upper part of the anode plate body 1 to form a hanging hole 13, so as to connect with the bolt by means of the through hole of the tubular rivet 2. Since the tubular rivet 2 has the characteristics of wear resistance and high strength, it can effectively strengthen the strength of the hanging hole 13 at the connection between the anode plate body 1 and the bolt. Among them, a connecting plate 3 connected to the rapping rod is also set, and the connecting plate 3 is fixedly connected to the anode plate body 1, and its thickness is greater than the thickness of the anode plate body 1. Then, when the rapping rod is running, the connecting plate 3 is used as the main force-bearing component, and the strength of the connecting plate 3 itself can effectively meet the needs of the rapping rod operation, so as to effectively avoid the situation in the prior art where the hanging hole 13 is severely worn and the gap appears, thereby achieving the purpose of extending the service life of the device.

[0042] In addition, by providing a bending portion 11 and a recessed portion 12, and the bulging direction of the bending portion 11 is opposite to the recessed direction of the recessed portion 12, the recessed portion 12 can effectively increase the dust adsorption area compared to the inclined bending edge in the prior art under the same size, so as to achieve the purpose of improving the dust interception and adsorption effect.

[0043] It should be particularly noted that the anode plate body 1 , the recessed portion 12 and the bent portion 11 are formed in an integrated manner, such as by cold pressing and bending.

[0044] In this embodiment, the shape of the recessed portion 12 is further limited so as to further increase the dust adsorption area and enhance the dust adsorption and interception effect.

[0045] Specifically, the recessed portion 12 is arranged in a "U" shape, and both side walls of the recessed portion 12 gradually approach along the direction of its center line from outside to inside, that is, obtuse angles are formed between the side walls and the bottom wall of the recessed portion 12. Therefore, compared with the recessed portion 12 having a rectangular chamber, the chamber with obtuse angles between the side walls and the bottom wall can further increase the adsorption area for dust, thereby improving the adsorption and interception effect of dust.

[0046] In addition, both side walls of the recessed portion 12 are provided with arc-shaped bending edges 121 that bulge along the center line direction of the recessed portion 12. Since the straight line is the shortest distance between two points, at the same distance, the contact area between the arc-shaped bending edge 121 and dust is larger than that of a flat bending edge, so the adsorption and interception effect of dust can be further improved.

[0047] In other embodiments, at least two of the tubular rivet members 2 located above the anode plate body 1 are provided to improve the stability during suspension.

[0048] In this embodiment, the thickness of the anode plate body 1 is 0.6 mm - 2 mm, and the thickness of the connecting plate 3 is 5 mm - 8 mm.

[0049] It should be noted that in the prior art, the thickness of the anode plate body 1 is usually 0.5 mm. Therefore, the thickness of the anode plate body 1 is increased here to improve its own strength and extend its service life.

[0050] In addition, by making the thickness of the connecting plate 3 much larger than that of the anode plate body 1, the connecting plate 3 as the main stress-bearing component can effectively meet the strength requirements during the operation of the vibrating rod, ensuring that no fracture or damage occurs.

[0051] In this embodiment, the anode plate body 1 and the connecting plate 3 are fixedly connected by the tubular rivet member 2 or by welding.

[0052] In other embodiments, the sizes of the bulge of the bending portion 11 and the depression of the recessed portion 12 are further defined. Specifically, the maximum horizontal distance D between the bending portion 11 and the recessed portion 12 is 55 mm - 65 mm, so as to avoid excessive distance between the bending portion 11 and the recessed portion 12 from affecting the overall strength of the anode plate structure and improve the stability during the application of the overall structure.

[0053] In this embodiment, the bending portion 11 includes a first bending edge 111, a second bending edge 112, and a third bending edge 113 that are sequentially connected and surround to form a rectangular open chamber.

[0054] Among them, the first bending edge 111 is connected to the recessed portion 12.

[0055] It should be noted that the length of the third bent edge 113 is less than that of the first bent edge 111, that is, the third bent edge 113 will not extend above the recess 12, so as not to interfere with the dust interception and adsorption effect of the recess 12, ensuring that the recess 12 can fully contact and adsorb dust, and improving the dust interception and adsorption effect.

[0056] In addition, when the recess 12 cooperates with the bent portion 11, it can also play a role in preventing secondary dust generation.

[0057] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
