To improve the dust removal efficiency and reduce the dust emission concentration has always been one of the research topics in the field of electrostatic precipitation. Currently, the commonly used technologies at home and abroad are moving electrode and wet electrostatic precipitators. However, the actual use situation shows that the moving electrode has poor reliability, high failure rate, and high operation and maintenance costs, and the wet electrostatic precipitator has a complex process and high investment costs, which are gradually not accepted by the market. At present, the commonly used dust collection anode plates (such as C-type, Z-type, etc.) configured in the field of electrostatic precipitators usually have small windproof grooves with a depth of ≤25 mm in the grooves. There is only one side designed with small windproof grooves, while the other side has no small windproof grooves.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions of the present application in conjunction with the drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present application.
[0030] To facilitate the understanding of this embodiment, the following briefly introduces the application scenario and design concept of the embodiments of the present application.
[0031] The commonly configured dust collection anode plates in the field of electrostatic precipitators usually have small windproof grooves with a groove depth less than or equal to 25 mm, and the action area is small during the regular rapping and dust cleaning process. The prior art solutions connect a large-sized windproof groove outside the small windproof groove through a connecting piece, but manual assembly is required, resulting in a large amount of manual labor.
[0032] Based on this, the embodiments of the present application provide a double windproof groove anode plate and an electrostatic precipitator.
[0033] Embodiment 1
[0034] The present application provides a double windproof groove anode plate, which combines with Figure 1 As shown in
[0035] The double windproof groove group includes two first windproof grooves 2, and the two first windproof grooves 2 are respectively fixedly connected to both ends of the anode plate body 1 and integrally formed; the two first windproof grooves 2 open towards both sides of the anode plate body 1 and are arranged oppositely; wherein, the joint surface of the first windproof groove 2 and the anode plate body 1 is the first surface, and the first windproof groove 2 is symmetrically structured with the midline of the first surface as the axis of symmetry.
[0036] In the present application, two relatively arranged first windproof grooves 2 are integrally connected to both ends of the anode plate body 1. The integrally formed structure has good stability. During actual application and assembly, manual installation is no longer required, which can reduce the manual labor amount while ensuring the dust removal effect. In addition, the first windproof groove is symmetrically structured with respect to the midline of the first surface, which is used to capture the secondary dust on both sides of the anode plate, expanding the secondary dust capture area and being beneficial to improving the dust removal efficiency.
[0037] Combined with the first aspect, combined with Figure 2 As shown in
[0038] The size range of traditional anode plates is 380 - 750 mm. Common ones include the 385Z-type anode plate with a size of 385 mm and the 480C-type anode plate with a size of 480 mm. The groove depth of the upper windproof groove on the traditional anode plate is less than or equal to 25 mm, and the distance between two adjacent traditional anode plates is usually about 20 mm.
[0039] During the dust collection process of the electrostatic precipitator, after the flue gas enters the high-voltage field strength, the charged dust is separated from the flue gas under the action of the electric field force and moves towards the anode plate direction. Finally, the dust is adsorbed on the surface of the anode plate. Usually, the dust collected on the surface of the anode plate needs to accumulate to a certain thickness before rapping is carried out to rap the flaky or agglomerated dust into the dust collector.
[0040] The functions of the upper windproof groove on the traditional anode plate are:
[0041] 1. In the traditional anode plate, the groove depth of the windproof grooves in the static flow regions A and B is small, the distance from the outer surface of the trapped dust to the flue gas flow is very small, and the flue gas flow velocity changes continuously when the flue gas enters the electric field. When the dust layer accumulates to a certain thickness in a local area, the surface layer will be directly washed or rolled up by the flue gas, causing some of the dust trapped on the anode plate surface to return to the flue gas flow again, greatly reducing the dust removal effect. By setting windproof grooves at one end and / or both ends of the traditional anode plate, the direct washing of the flue gas flow can be prevented, enabling the dust to enter the static flow regions A and B (combined with Figure 3 as shown in Figure 3 , the arrow direction in
[0042] is the flue gas flow direction).
[0043] 2. During the process of rapping and timing ash cleaning, a sufficiently large rapping force is required, and the distribution of the rapping force magnitudes at the upper, lower, front, and rear parts of the anode plate row is very uneven. During the separation of flaky dust, a part of it is broken, and the fine dust at its edge will return to the flue gas flow again. This fine dust is called secondary dust emission. At this time, this small windproof groove will recapture the dust of a small part of the secondary dust emission caused by the anode rapping.
[0044] 3. The gap between adjacent traditional anode plates is usually about 20 mm, that is, the groove depth of the static flow region C is small, and the space for collecting charged dust is small, but it is beneficial to improving the dust removal efficiency.
[0045] In this application, the length range of the connecting plate 23 is set to 80 - 150 mm. Then, on the basis of the traditional anode plate, a first windproof groove with a larger size is integrally connected, which can also prevent the direct washing of the trapped dust by the flue gas flow and increase the structural rigidity. In addition, on the basis of the small windproof groove, the capture area of the secondary dust emission can be expanded, thereby improving the dust removal efficiency.
[0046] In addition, since the first windproof groove 2 is a symmetric structure, compared with the structure of the unilateral small windproof groove in the traditional anode plate, the first windproof groove 2 can capture the dust emission on both sides of the anode plate.
[0047] In this embodiment, the length of the connecting plate 23 is 100 mm.
[0048] Combined with the first aspect, the first capture plate 21 and the second capture plate 22 are symmetrically arranged with respect to the center of the connecting plate 23, and the ends of the first capture plate 21 and the second capture plate 22 both have capture parts that are buckled inward toward the anode plate body 1. The escaped secondary dust emission is blocked by the capture parts.
[0049] In combination with the first aspect, the included angle range between the first capture plate 21, the second capture plate 22 and the connection plate 23 is 60° - 150°.
[0050] It can be understood that there can be a certain angle between the first capture plate 21 and the connection plate 23, which can be determined according to the actual dust removal requirements and will not be limited here.
[0051] In combination with the first aspect, the groove depth dimension of the first windproof groove 2 is 50 mm. That is, the dimensions of the first capture plate 21 and the second capture plate 22 are 50 mm. Compared with the traditional windproof groove on the anode plate with a groove depth less than or equal to 25 mm, due to the increase in the groove depth of the first windproof groove 2 provided in this application, that is, the depths (H1, H2, H3) of the static flow regions A, B, and C increase, the scouring of the captured dust by the flue gas flow is greatly reduced, and most of the dust from the secondary dust raising caused by anode rapping is recaptured, which can significantly improve the efficiency of capturing secondary dust raising.
[0052] In combination with the first aspect, both ends of the anode plate body 1 have second windproof grooves 11, and the length range of the second windproof grooves 11 is 40 - 50 mm.
[0053] In combination with the first aspect, the opening directions of the two second windproof grooves 11 are on the same side or opposite sides of the anode plate body 1.
[0054] It can be seen that the anode plate body 1 in this application is the same as the traditional anode plate, but by integrally connecting large-sized first windproof grooves 2 with a higher groove depth at both ends, the depth of the static flow region is increased, thereby reducing the scouring of dust by the flue gas flow. At the same time, secondary dust raising is captured during the rapping and timed dust cleaning process, improving the dust removal efficiency.
[0055] In the second aspect, the embodiments of this application provide an electrostatic precipitator, and the electrostatic precipitator includes a plurality of double windproof groove anode plates as described above.
[0056] In combination with the second aspect, a plurality of double windproof groove anode plates are arranged at intervals.
[0057] Combined Figure 4 As shown, a plurality of double windproof groove anode plates are arranged at intervals in the electrostatic precipitator. The integrally formed double windproof groove anode plates do not require manual assembly, with less manual labor. Moreover, the effect of preventing air flow scouring and the effect of capturing secondary dust raising of the large-sized first windproof grooves 2 are improved, resulting in an improvement in the dust removal efficiency. Among them, the arrow direction is the air flow direction.
