Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal equipment technology, and more specifically, to a dust blowing device for an electrostatic precipitator. Background Technology
[0002] The working principle of an electrostatic precipitator is to use a high-voltage electric field to ionize the flue gas. The dust in the airflow becomes charged and separates 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, while the positive electrode is made of metal plates with different geometric shapes and is called the dust collection electrode. Compared with other dust removal equipment, electrostatic precipitators consume less energy, have higher dust removal efficiency, and are suitable for removing dust particles of 0.01-50μm from flue gas. They can also be used in situations with high flue gas temperature and high pressure.

Detailed Implementation
[0012] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0013] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0014] This utility model provides, for example Figure 1-4 The soot blowing device for an electrostatic precipitator shown includes an air storage box 1, a heater 2 installed inside the air storage box 1, a lifting piston 3 installed inside the air storage box 1, the lifting piston 3 dividing the air storage box 1 into two air storage spaces 4, the heater 2 installed in the upper air storage space 4, a lifting frame 5 installed on the air storage box 1, the lifting frame 5 can drive the lifting piston 3 to move up and down, a moving piston 6 installed in the air storage space 4, a moving frame 7 installed on the air storage box 1, the moving frame 7 can drive the moving piston 6 to move, a mixing box 8 installed on one side of the air storage box 1, the gases in the two air storage spaces 4 can be mixed in the mixing box 8, an air outlet pipe 9 installed on the mixing box 8, the outlet end of the air outlet pipe 9 is connected to the nozzle on the electrostatic precipitator through a multi-port pipe.
[0015] The process of blowing dust from an electrostatic precipitator using this device is as follows: Nitrogen gas in one gas storage space 4 is heated by heater 2, and nitrogen gas is introduced into two gas storage spaces 4. The moving frame 7 drives the moving piston 6 to move, so that the nitrogen gas in the two gas storage spaces 4 can be discharged into the mixing box 8, and then discharged into the electrostatic precipitator through the exhaust pipe 9, thus blowing dust from the electrostatic precipitator. By installing a temperature sensor in the mixing box 8, the temperature of the nitrogen gas can be detected. When the temperature is too high or too low, the lifting frame 5 drives the lifting piston 3 to move up and down, thereby adjusting the cross-sectional size of the two gas storage spaces 4. When the moving frame 7 drives the moving piston 6 to move, the nitrogen gas in the gas storage spaces 4 can be discharged in a proportional manner, thus facilitating the adjustment of the nitrogen gas temperature.
[0016] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The lifting frame 5 includes a lifting platform 10 located above the air storage tank 1. Multiple lifting rods 11 are installed on the lower surface of the lifting platform 10. Multiple inlets and outlets 12 are opened at the upper end of the air storage tank 1. The lower end of the lifting rod 11 passes through the inlet and outlet 12 and connects to the upper surface of the lifting piston 3. A first sealing ring 13 is installed at the inlet and outlet 12. Multiple first electric telescopic rods 14 are installed at the upper end of the air storage tank 1. The telescopic ends of the first electric telescopic rods 14 are connected to the lifting platform 10.
[0017] The process of the lifting frame 5 driving the lifting piston 3 to move up and down is as follows: the first electric telescopic rod 14 is started to move up and down, which can drive the lifting rod 11 to move up and down. The lifting rod 11 can drive the lifting piston 3 to move up and down. The first sealing ring 13 can prevent nitrogen from leaking out from the inlet and outlet 12.
[0018] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 4 The movable piston 6 includes a telescopic piston 15 located above and below the lifting piston 3. A holding piston 16 is provided on one side of the telescopic piston 15. A square groove 17 is opened on the side of the holding piston 16 near the telescopic piston 15. One end of the telescopic piston 15 extends into the square groove 17. Multiple guide holes 18 are opened on both the holding piston 16 and the telescopic piston 15. Guide rods 19 are provided in the guide holes 18. The two ends of the guide rods 19 on the holding piston 16 are installed in the gas storage box 1. The guide rods 19 on the telescopic piston 15 are installed on the lifting piston 3. A second sealing ring 20 is installed in the guide hole 18. The movable frame 7 consists of multiple second electric telescopic rods installed in the gas storage box 1. The telescopic ends of the second electric telescopic rods can be connected to the holding piston 16.
[0019] The process of moving piston 6 is as follows: When lifting piston 3 moves up and down, the telescopic piston 15 can be moved up and down through the engagement of guide rod 19 and guide hole 18, which makes it easier to adjust the size of gas storage space 4. The second sealing ring 20 can prevent nitrogen from leaking out from guide hole 18. The square groove 17 can facilitate the up and down movement of telescopic piston 15. The second electric telescopic rod can be activated to extend or retract. The second electric telescopic rod can drive the holding piston 16 and telescopic piston 15 to move, which makes it easier to discharge nitrogen.
[0020] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The gas storage space 4 has an outlet 21 on one side, and a first one-way valve 22 is installed at the outlet 21. The outlet of the first one-way valve 22 can be connected to the inlet of the mixing box 8 through a pipe. The gas storage space 4 has an inlet 23 on one side, and a second one-way valve 24 is installed at the inlet 23. The inlet of the second one-way valve 24 is connected to the nitrogen pipe. The heater 2 has a partition 25 on one side, which can separate the heater 2 and the outlet 21. The heater 2 and the inlet 23 are located on the same side of the partition 25. The partition 25 has a notch to avoid the guide rod 19.
[0021] The process of gas intake and exhaust in the gas storage space 4 is as follows: When the moving piston 6 moves outward, nitrogen can enter the gas storage space 4 through the nitrogen pipeline, the second one-way valve 24, and the air inlet 23. The nitrogen entering the heater 2 can be heated. The heated nitrogen can bypass the partition 25 from below, thereby extending the heating time. When the moving piston 6 moves inward, nitrogen can enter the mixing box 8 through the air outlet 21 and the first one-way valve 22.
[0022] Refer to the instruction manual appendix Figure 1 A flexible pad 26 is installed at the lower end of the partition 25. One end of the flexible pad 26 is connected to the lower end of the holding piston 16. A vent 27 is opened on the side of the flexible pad 26 near the holding piston 16. Multiple transverse reinforcing ribs 28 are installed on the flexible pad 26. After nitrogen enters the gas storage space 4, the nitrogen can be heated by the heater 2. The heated nitrogen can move to the bottom of the flexible pad 26 through the partition 25, the flexible pad 26, and the vent 27, and then be discharged through the outlet 21. In this way, the nitrogen can be heated. When the holding piston 16 moves, the flexible pad 26 can be bent, which can prolong the heating time of the nitrogen. The transverse reinforcing ribs 28 can make the flexible pad 26 fit tightly against the two sides of the gas storage box 1, reducing the leakage of nitrogen from the two sides of the flexible pad 26 to the bottom.
