[0033] Please refer to Figures 1 to 3 , and now the air flow distribution device of the electrostatic precipitator provided by the present utility model will be described. The air flow distribution device of the electrostatic precipitator is used to be installed inside the inlet of the electrostatic precipitator, and includes a plurality of spoiler components arranged at intervals along the air flow direction. The spoiler component includes a suspension member 10, a spoiler plate 20 and a flow guide member 30. The suspension member 10 is fixed on the inner wall of the inlet of the electrostatic precipitator; the spoiler plate 20 is connected to the suspension member 10, and the spoiler plate 20 has a plurality of spoiler holes 21; the flow guide member 30 is fixedly connected to the spoiler plate 20, and the flow guide member 30 is used to guide the air flow passing through the spoiler holes 21.

[0034] The air flow distribution device of the electrostatic precipitator provided in this embodiment, compared with the prior art, the suspension member 10 is used for the installation of the spoiler 20 inside the inlet of the electrostatic precipitator. When the flue gas enters the inlet of the electrostatic precipitator, due to the arrangement of a plurality of spoilers 20, and each spoiler 20 is provided with spoiler holes 21 and a flow guiding member 30, the flue gas can be quickly dispersed, so that it is evenly distributed inside the inlet of the electrostatic precipitator, ensuring the uniform distribution of dust in the air flow, and thus efficient dust removal treatment can be carried out after entering the interior of the electrostatic precipitator. The structure of the electrostatic precipitator of the present utility model can optimize the air flow distribution effect, and further improve the dust removal efficiency of the electrostatic precipitator.

[0035] In some embodiments, a specific implementation manner of the above-mentioned flow guiding member 30 can adopt the structure as shown in Figure 1 . Refer to Figure 1 , the flow guiding member 30 is installed on one side of the spoiler 20 facing the air flow inlet side, or the flow guiding member 30 is installed on one side of the spoiler 20 facing away from the air flow inlet side.

[0036] Installing the flow guiding member 30 on either side of the spoiler 20 can achieve the effect of evenly distributing the air flow, but installing the flow guiding member 30 on the side of the spoiler 20 facing away from the air flow has a better effect and does not hinder the passage of the air flow.

[0037] In some embodiments, a specific implementation manner of the above-mentioned flow guiding member 30 can adopt the structure as shown in Figure 1 . Refer to Figure 1 , the flow guiding member 30 is a conical cylinder, and the inner diameter of the conical cylinder gradually increases along the direction of the air flow. The air flow flows inside the inlet, first enters from the small end of the conical cylinder. By arranging a plurality of conical cylinders, the air flow passing through the spoiler holes 21 can be divided into multiple strands, and the multiple strands of air flow are evenly distributed in different conical cylinders, so as to achieve the uniform distribution of the air flow.

[0038] Correspondingly, refer to Figure 1 and Figure 3 , the spoiler 20 is provided with a limiting member 22, and a limiting groove 23 is provided on the side of the limiting member 22 facing the conical cylinder. The two ends of the conical cylinder are respectively abutted against the inner walls of different limiting grooves 23. Between two adjacent spoilers 20, the limiting member 22 on one spoiler 20 is arranged on the side facing away from the air flow inlet, and the limiting member 22 on one spoiler 20 is arranged on the side facing the air flow inlet. Fixing the conical cylinder through the limiting member 22 not only facilitates the loading and unloading process of the conical cylinder, but also can prevent the conical cylinder from being skewed under the drive of the air flow during use.

[0039] In some embodiments, a variant implementation manner of the above-mentioned flow guiding member 30 can adopt the structure as shown in Figure 2 . Refer to Figure 2, the flow guide member 30 includes a first support plate 31 and a second support plate 32 arranged at an angle. The first sides of the first support plate 31 and the second support plate 32 are butted against each other. An air vent hole 36 corresponding to the spoiler hole 21 is provided on the second support plate 32. Arc-shaped plates 33 are provided on the second sides of the first support plate 31 and the second support plate 32. The second side is the opposite side of the first side. The plate surface of the arc-shaped plate 33 is perpendicular to the plate surface of the first support plate 31 or the second support plate 32. A plurality of jacks 34 are provided on each arc-shaped plate 33. An insertion member 35 is connected between the two arc-shaped plates 33;

[0040] Among them, the second support plate 32 is used to be attached to the spoiler 20 for installation. By rotating the first support plate 31 or the second support plate 32, different jacks 34 on the two arc-shaped plates 33 can be made to correspond, realizing the switching of the angle between the first support plate 31 and the second support plate 32.

[0041] After the air flow passes through the spoiler hole 21, it enters the space between the first support plate 31 and the second support plate 32 through the air vent hole 36 on the second support plate 32. Since the first support plate 31 and the second support plate 32 are arranged at an angle, the air flow will flow out of the space between the first support plate 31 and the second support plate 32 along the side wall of the first support plate 31, and then flow to the next spoiler 20.

[0042] In this embodiment, by arranging the insertion member 35 and the arc-shaped plates 33 between the first support plate 31 and the second support plate 32, it is convenient to adjust the angle between the first support plate 31 and the second support plate 32, so as to adapt to different dust removal situations.

[0043] In some embodiments, an improved implementation manner of the above-mentioned flow guide member 30 can adopt the structure as Figure 2 shown. Refer to Figure 2 , the flow guide member 30 further includes a hook 37. The hook 37 is in a V shape. One inner side wall of the hook 37 is attached to the first support plate 31, and the other inner side wall is parallel and spaced from the plate surface of the second support plate 32. The other side wall of the hook 37 is used for hanging on the spoiler hole 21. By arranging the hook 37, the hook 37 can be hung on the spoiler hole 21, which not only facilitates the installation of the flow guide member 30, but also does not affect the air flow passing through the spoiler hole 21. This structure is simple to operate, convenient to use, and reduces the labor intensity.

[0044] Specifically, one side wall of the hook 37 is detachably connected to the first support plate 31 through a threaded connection member. Since the angle between the first support plate 31 and the second support plate 32 is adjustable, when the angle between the first support plate 31 and the second support plate 32 changes, the corresponding hook 37 can be replaced to adapt to the angle change between the first support plate 31 and the second support plate 32.

[0045] In some implementations, a specific implementation manner of the above-mentioned flow guide member 30 can adopt the structure as Figure 1 shown. Refer to Figure 1The guide members 30 on two adjacent spoilers 20 are arranged on opposite sides of the spoilers 20 .

[0046] After passing through a spoiler 20 , the airflow is dispersed by the guide member 30 , and then enters the guide member 30 on the next spoiler 20 , and passes through the spoiler 20 from inside the guide member 30 . This arrangement can improve the dispersion effect of the airflow.

[0047] In some embodiments, a specific implementation of the above-mentioned suspension member 10 can be as follows Figure 2 See the structure shown. Figure 2 The suspension member 10 includes a fixed block 11, a rotating shaft 12 and a hook 13. The fixed block 11 is fixedly connected to the inner wall of the entrance of the electrostatic precipitator; the rotating shaft 12 is rotatably connected to the fixed block 11, and the axial direction of the rotating shaft 12 is parallel to the plate surface of the spoiler 20; the hook 13 is fixedly connected to the rotating shaft 12, and the hook 13 is used to be fixedly connected to the spoiler hole 21. The hook 13 is connected to the spoiler hole 21 to facilitate the installation of the spoiler 20, saving time and effort; when the airflow passes through, due to the resistance of the airflow and the rotational connection of the hook 13 with the fixed block 11, the spoiler 20 can be pushed to produce a slight shake, and the shaking combined with the spoiler hole 21 set on the spoiler 20 can further improve the disrupting effect of the airflow.

[0048] In some embodiments, an improved implementation of the above spoiler 20 may adopt the following structure. Not shown in the figure, the apertures of the spoiler holes 21 on adjacent spoilers 20 are different. By setting different apertures, the airflow has different resistances when passing through different spoilers 20, thereby producing a further spoiler effect on the airflow.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
