Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrostatic precipitators, in particular to a grid-type combined anode row for an electrostatic precipitator. Background Technique
[0002] A wet electrostatic precipitator is a new dust removal device used to treat trace dust and fine particles. It is mainly used to remove harmful substances such as dust, acid mist, water droplets, and aerosols in humid gases. It is an ideal device for controlling air dust pollution. The main structure inside the wet electrostatic precipitator is an anode tube and a cathode wire. Among them, the anode tube is formed by combining multiple anode plates to form a grid-type anode row, which has a better dust removal effect.
[0003] However, during the transportation of the existing grid-type combined anode row for wet electrostatic precipitators, that is, the anode tube, one end is usually fixed with a flat plate, while the other end is not provided with a support structure similar to the flat plate, making it easier for the anode row to be bumped or worn at the corners during transportation, which is not conducive to the movement or transportation of the anode row; in addition, after the cathode wire tube with barbs passes through the anode tube, since the cathode wire is suspended at the top in the anode tube and is not stably reinforced at the bottom, when gas passes through the anode tube, it is difficult for the cathode wire to maintain a vertical state and is easy to swing left and right in the anode tube, resulting in an abnormal electric field not being generated in the anode tube and affecting the conduction efficiency of the anode tube. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a grid-type combined anode row for an electrostatic precipitator to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A grid-type combined anode row for an electrostatic precipitator, including an anode row.

Four corners of the top end of the activity plate are fixedly connected with sleeves. The outer wall of the sleeve is movably threaded through with fastening bolts. The outer wall of the top end of the anode row is fixedly connected with a fixed plate. Four corners of the bottom end of the fixed plate are threadedly connected with vertical rods. A second pipe orifice is opened at the bottom end of the anode row. Both inner walls of the second pipe orifice are fixedly connected with second clamping rods.

[0011] Preferably, a bottom plate is fixedly connected to the bottom end of the vertical rod.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0023] As Figures 1 to 4 shown, the grid-type combined anode row for the electric dust collector in this embodiment includes an anode row 2. A first pipe orifice 5 is opened at the top end of the anode row 2. First clamping rods 4 are fixedly connected to the inner walls on both sides of the first pipe orifice 5. Top half-rings 3 are fixedly connected to one ends of the two first clamping rods 4. A movable plate 9 is provided in the middle of the anode row 2. Sleeve barrels 8 are fixedly connected to the four corners at the top end of the movable plate 9. Tightening bolts 7 are movably threaded through the outer walls of the sleeve barrels 8. A fixing plate 1 is fixedly connected to the outer wall at the top end of the anode row 2. Vertical rods 6 are threadedly connected to the four corners at the bottom end of the fixing plate 1. A second pipe orifice 13 is opened at the bottom end of the anode row 2. Second clamping rods 11 are fixedly connected to the inner walls on both sides of the second pipe orifice 13. Bottom half-rings 12 are fixedly connected to one ends of the second clamping rods 11.
[0024] Specifically, the anode row 2 is a polygonal anode tubular structure formed by enclosing multiple anode plates through welding. Its shape resembles a grille, and the cross-sectional shape is "honeycomb-shaped". Since it is mainly used for dust removal of wet gas with a large water content, it is set as a tubular structure. Both the first clamping rod 4 and the second clamping rod 11 are made of insulating materials, so that when the cathode tube contacts the first clamping rod 4 or the second clamping rod 11 through the top half-ring 3 and the bottom half-ring 12, charge transfer is not likely to occur, thereby reducing the probability of contact between the cathode and the anode. The inner diameters of the top half-ring 3 and the bottom half-ring 12 are the same and are adapted to the outer diameter of the cathode tube, so that the cathode tube is reinforced within the anode row 2, thereby reducing the probability of the cathode tube swinging left and right within the anode tube. The middle part of the movable plate 9 is hollowed out, so that the movable plate 9 can slide around the anode row 2. At the same time, the size of the movable plate 9 is the same as that of the fixed plate 1, so that when the movable plate 9 moves to one end of the anode row 2 away from the fixed plate 1 and is laid horizontally, both ends of the anode row 2 can be supported simultaneously, thereby reducing the probability of the corners of the anode row 2 being knocked or worn. The inner diameter of the sleeve 8 is larger than the outer diameter of the vertical rod 6, so that the sleeve 8 can slide smoothly along the vertical rod 6. The vertical rod 6 can play a role in connecting the fixed plate 1 and the movable plate 9, and at the same time enable the movable plate 9 to maintain a connection relationship with the anode row 2. At the same time, the vertical rod 6 can be disassembled from the fixed plate 1 to reduce interference with the subsequent installation of the anode row 2 in the wet electrostatic precipitator. The lengths of the second clamping rod 11 and the first clamping rod 4 are the same, so that both the top half-ring 3 and the bottom half-ring 12 can be located in the middle of the inner side of the anode tube.
[0025] Further, a rubber pad 14 is fixedly connected to the end of the fastening bolt 7. The rubber pad 14 is movably connected to the sleeve 8. The rubber pad 14 can make the end of the fastening bolt 7 fit tightly with the vertical rod 6 to increase the biting friction between the fastening bolt 7 and the vertical rod 6, thereby facilitating the temporary locking of the sleeve 8 on the vertical rod 6 by the fastening bolt 7.
[0026] Further, the sleeve 8 is movably sleeved on the vertical rod 6. The rubber pad 14 is movably connected to the vertical rod 6 through the sleeve 8 and the fastening bolt 7. After the sleeve 8 is locked on the vertical rod 6 by the fastening bolt 7, it can drive the movable plate 9 to be locked on the vertical rod 6 at the same time, so that the movable plate 9 can remain fixed after moving to the other end of the anode row 2, thereby facilitating the support of the other end of the anode row 2 by the movable plate 9.
[0027] Further, the movable plate 9 is movably connected to the vertical rod 6 through the sleeve 8. The movable plate 9 is movably sleeved on the anode row 2 through the vertical rod 6. The movable plate 9 can slide along the periphery of the anode row 2, so that the position of the movable plate 9 on the anode row 2 can be changed flexibly, thereby realizing the sliding of the movable plate 9 to the other end of the anode row 2.
[0028] Furthermore, the interior of the first pipe orifice 5 at the top of the anode row 2 communicates with the interior of the second pipe orifice 13 at the bottom, enabling a pipe-like structure to be formed inside the anode row 2, allowing the flue gas to flow through the anode pipes in the anode row 2, facilitating sufficient contact between the flue gas and the anode pipes and the cathode wire pipes, thereby improving the dust removal efficiency of the electrostatic precipitator.
[0029] Furthermore, the top half-ring 3 is fixedly connected to the first pipe orifice 5 through the first clamping rod 4. The top half-ring 3 and the bottom half-ring 12 are located on the same vertical line, such that after the cathode wire pipe contacts the top half-ring 3 and the bottom half-ring 12, both the top end and the bottom end of the cathode wire pipe can be on the same vertical line, thereby reducing the probability of the cathode wire pipe swinging left and right inside the anode pipe.
[0030] Furthermore, a bottom plate 10 is fixedly connected to the bottom end of the vertical rod 6. When the movable plate 9 slides to the bottom end of the vertical rod 6, the bottom plate 10 can be in contact with the ground surface of the movable plate 9, making it difficult for the movable plate 9 to slide away from the vertical rod 6, playing a role in limiting the movable plate 9. At the same time, when the anode row 2 is placed vertically, the bottom end of the anode row 2 can be lifted off the ground, thereby avoiding collision or abrasion between the bottom end of the anode row 2 and the ground.
[0031] The usage method of this embodiment is as follows: When moving or transporting the electrostatic precipitator with the grid-type combined anode row 2, the anode row 2 needs to be first vertically erected on the ground. At this time, the bottom plate 10 at the bottom end of the vertical rod 6 will contact the ground, causing the bottom end of the anode row 2 to be lifted to a height above the ground. Then, the fastening bolt 7 can be loosened to release the locking between the sleeve 8 and the vertical rod 6. Then, the movable plate 9 can be pushed to slide along the vertical rod 6 and the periphery of the anode row 2, causing the movable plate 9 to slide towards the bottom plate 10 until the bottom surface of the movable plate 9 fits the top surface of the bottom plate 10. At this time, the movable plate 9 will move to the bottom end of the anode row 2. Then, the fastening bolt 7 is tightened again to keep the movable plate 9 fixed at the bottom end of the anode row 2. Then, the anode row 2 can be horizontally laid down. At this time, both ends of the anode row 2 can be supported. Then, when installing and docking the anode row 2 with the electrostatic precipitator, the vertical rod 6 and the movable plate 9 can be first removed from the fixing plate 1 and the anode row 2. Then, the anode row 2 is fixed to the electrostatic precipitator. Then, when inserting the cathode wire pipe into the tubular structure inside the anode row 2, the bottom end of the cathode wire pipe needs to be first passed through the two symmetrically arranged top half-rings 3 at the first pipe orifice 5. Then, the cathode wire pipe is passed through the two symmetrically arranged bottom half-rings 12 at the second pipe orifice 13, strengthening the cathode wire pipe at the center inside the anode row 2, making it difficult for the cathode wire pipe to be disturbed by the incoming air flow.
[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
