Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic precipitators, in particular to a flue gas uniform distribution device for an electrostatic precipitator. Background Art

[0002] The working principle of the electrostatic precipitator is to use a high-voltage electric field to ionize the flue gas. The charged dust in the airflow is separated from the airflow under the action of the electric field. The negative electrode is made of metal wires with different cross-sectional shapes and is called the discharge electrode.

[0003] After searching, the Chinese patent with publication number CN207913956U discloses a flue gas uniform distribution device for an electrostatic precipitator. In this solution, one end of the air inlet pipe is connected to the air inlet diffuser, and a filter plate and a ash cleaning assembly consisting of a flap and an ash outlet pipe are arranged in the air inlet diffuser. The ash outlet pipe is connected to the air inlet diffuser, and the flap is hinged in the notch. When the dust in the flue gas is retained in the air inlet diffuser and accumulates on the side of the flap close to the filter plate under the action of gravity, the dust accumulated to a certain weight will flip the flap and then enter the ash hopper through the ash outlet pipe for treatment, thereby avoiding the accumulation of dust and improving the uniform distribution effect of the flue gas.

[0004] However, in a flue gas distribution device similar to the above-mentioned electrostatic precipitator, the filter plate is generally set in the middle of the device and is fixedly connected, which makes it inconvenient to replace the filter plate. As time goes by, more impurities will be adsorbed on the filter plate, affecting the flue gas passing efficiency. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] In view of the above background technology, the prior art has the disadvantages and defects of the inconvenience of replacing the filter plate, which affects the efficiency of the flue gas passing.

[0006] The utility model discloses a flue gas uniform distribution device for an electrostatic precipitator, comprising an air inlet pipe, a diverter pipe being provided at one end of the air inlet pipe, a uniform distribution plate being installed at the outlet of the diverter pipe, a filter plate being provided on the inner side of the air inlet pipe, the filter plate being slidably arranged with the air inlet pipe through a fixed frame, a triangular block and a slider being provided on the filter plate, a stopper being provided on the inner wall of the air inlet pipe, and an elastic component being provided between the stopper and the air inlet pipe.

[0007] Furthermore, the fixing frame includes side panels and a bottom panel, the side panels are connected to the bottom panel via fixing bolts, and the fixing bolts pass through the bottom panel and are threadedly connected to the side panels.

[0008] Furthermore, the triangular block and the slider are provided on both sides of the side panel, the triangular block is fixedly connected to the side panel, the two sliders are fixedly connected via a connecting rod, and the connecting rod is slidably connected to the side panel.

[0009] Furthermore, the elastic component includes a fixed plate, which is fixedly mounted on the air intake pipe. A sliding rod is slidably mounted on the fixed plate. One end of the sliding rod is fixedly connected to the block, and the other end of the sliding rod is connected to the fixed plate via a tension spring.

[0010] Furthermore, a cleaning brush is provided on one side of the filter plate, a limiting member is provided between the cleaning brush and the air inlet pipe, a driving rod is installed on one side of the cleaning brush, and one end of the driving rod passes through the air inlet pipe.

[0012] Furthermore, a guide groove is provided on one side of the side plate, a guide plate is provided on the inner wall of the air intake pipe at a position corresponding to the guide groove, and the guide groove and the guide plate are slidably arranged.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The utility model is provided with a fixed frame, an elastic component, a stopper, a slider, a triangular block and other components. During operation, the stopper component cooperates with the triangular block component to limit the position of the fixed frame, indirectly limiting the position of the filter plate. The filter plate is driven to slide by the fixed frame, so that the slider drives the stopper to move and compress the elastic component. When the stopper moves to the other side of the slider, the fixed frame is driven to move in the opposite direction. At this time, the stopper cannot smoothly bypass the triangular block, thereby achieving the effect of convenient disassembly, facilitating the replacement of the filter plate, and avoiding clogging of the filter plate to affect the passing efficiency of the smoke.

[0015] 2. The utility model is provided with a guide rod, a driving rod, a cleaning brush, a bottom plate, a fixing bolt and other components. During the working process, the driving rod component cooperates with the guide rod component to control the movement of the driving rod component, and the driving rod drives the cleaning brush to slide on the guide rod. At the same time, the cleaning brush rubs the surface of the filter plate, thereby achieving the effect of cleaning the filter plate. By removing the fixing bolt from between the bottom plate and the side plate, the bottom plate can be disassembled, which is convenient for removing impurities inside the intake pipe.

DETAILED DESCRIPTION

[0023] The following diagrams illustrate various embodiments of the present invention. For clarity, many physical details will be included in the following description. However, it should be understood that these physical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these physical details are not essential. Furthermore, to simplify the illustrations, some commonly used structures and components are depicted in a simplified schematic manner.

[0024] See also Figure 1 、 Figure 2 、 Figure 3 The utility model provides a flue gas uniform distribution device for an electrostatic precipitator, comprising an air inlet pipe 1, a diverter pipe 2 being provided at one end of the air inlet pipe 1, a uniform distribution plate 3 being installed at the outlet of the diverter pipe 2, a filter plate 4 being provided on the inner side of the air inlet pipe 1, the filter plate 4 being slidably arranged with the air inlet pipe 1 through a fixed frame 5, a triangular block 6 and a slider 7 being provided on the filter plate 4, a stopper 8 being provided on the inner wall of the air inlet pipe 1, and an elastic component 10 being provided between the stopper 8 and the air inlet pipe 1.

[0025] In this embodiment, when the filter plate 4 needs to be disassembled and replaced, the staff drives the fixed frame 5 to move the filter plate 4, and the fixed frame 5 drives the slider 7 to follow the movement. The slider 7 drives the stopper 8 to move to one side and compresses the elastic component 10. When the stopper 8 moves to the other side of the slider 7, the direction drives the fixed frame 5 to move, and the fixed frame 5 drives the filter plate 4 to follow the movement. At this time, the stopper 8 moves along the direction of the slider 7 and smoothly bypasses the triangular block 6, thereby releasing the restriction on the fixed frame 5, thereby achieving the effect of convenient disassembly of the filter plate 4. During installation, the fixed frame 5 and the filter plate 4 are directly pushed into the air intake pipe 1, and the stopper 8 is restricted by the triangular block 6. The smoke entering the air intake pipe 1 is filtered by the filter plate 4 and then sent out through each diversion pipe 2.

[0026] like Figure 5 As shown, the fixing frame 5 includes a side panel 501 and a bottom panel 502. The side panel 501 and the bottom panel 502 are connected via a fixing bolt 503. The fixing bolt 503 passes through the bottom panel 502 and is threadedly connected to the side panel 501. By removing the fixing bolt 503, the restriction between the bottom panel 502 and the side panel 501 is released, and the bottom panel 502 can be removed from the side panel 501. A sealing gasket is provided between the bottom panel 502 and the intake pipe 1.

[0027] like Figure 4 As shown, triangular blocks 6 and sliders 7 are provided on both sides of the side panel 501. The triangular blocks 6 are fixedly connected to the side panel 501. The two sliders 7 are fixedly connected by a connecting rod 9. The connecting rod 9 is slidably connected to the side panel 501, so that the force on both sides of the side panel 501 is evenly distributed, thereby improving the stability of the device during operation.

[0028] like Figure 3 As shown, the elastic component 10 includes a fixed plate 1001, which is fixedly installed on the intake pipe 1, and a slide rod 1002 is slidably installed on the fixed plate 1001. One end of the slide rod 1002 is fixedly connected to the block 8, and the other end of the slide rod 1002 is connected to the fixed plate 1001 through a tension spring 1003. When the block 8 is pushed by the triangular block 6 or the slider 7, the block 8 moves to one side and pushes the slide rod 1002 to move with it. The slide rod 1002 drives the tension spring 1003 to stretch and store force. When the resistance on the block 8 disappears, the tension spring 1003 drives the slide rod 1002 to move and drives the block 8 to automatically reset.

[0029] like Figure 2As shown, a cleaning brush 11 is provided on one side of the filter plate 4, and a limiting member is provided between the cleaning brush 11 and the air inlet pipe 1. A driving rod 12 is installed on one side of the cleaning brush 11, and one end of the driving rod 12 passes through the air inlet pipe 1. A sealing ring is provided between the driving rod 12 and the air inlet pipe 1. The staff controls the movement of the driving rod 12, and the driving rod 12 drives the cleaning brush 11 to move. The cleaning brush 11 rubs on the filter plate 4, thereby removing impurities on the filter plate 4, and the impurities can be directly taken out when the bottom plate 502 is removed.

[0030] The limiting member includes a limiting rod 13, which is fixedly mounted on the air inlet pipe 1. The limiting rod 13 and the cleaning brush 11 are slidingly arranged to limit the moving direction of the cleaning brush 11 to prevent the cleaning brush 11 from sliding and deflecting.

[0031] Combine Figure 2 、 Figure 4 As shown, a guide groove 14 is provided on one side of the side plate 501, and a guide plate is provided on the inner wall of the air intake pipe 1 at the position corresponding to the guide groove 14. The guide groove 14 and the guide plate are slidingly arranged to limit the moving direction of the side plate 501 by the guide plate, so that the side plate 501 and the filter plate 4 are both installed in the specified position.

[0032] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
