Description

Technical Field

[0001] This utility model relates to the field of dust collection technology, and in particular to a dust collection device for power plants. Background Technology

[0002] A slag cooler, also known as a slag chiller, consists mainly of an outer cylinder with a transmission device welded to it and an inner cylinder with fixed spiral guide blades welded to it. The inner cylinder comes in various models, including multi-tube and sleeve types. Slag lifting plates are welded between the fixed spiral guide blades inside the inner cylinder. When the slag cooler is driven to rotate slowly by the transmission device, the high-temperature slag is guided forward by the spiral blades in the inner cylinder of the sleeve. At the same time, during rotation, the slag lifting plates lift the slag upwards. After reaching a certain height, the slag is thrown downwards. Cooling water flows in the opposite direction in the jacket between the inner and outer cylinders to remove heat. Cooling air in the inner cylinder lifts the slag lifting plates and throws the hot air heated by the slag away, thus gradually cooling the hot slag.

[0003] Traditional power plant boiler slag coolers generate large amounts of dust during slag discharge, severely polluting the environment. Existing patent application CN202121133070.6 proposes a power plant dust collection device, including a first suction pipe. One end of the first suction pipe is located above the slag discharge port of the slag cooler, and a first suction volume regulating valve is installed on it. The other end of the first suction pipe is connected to one end of a bag filter, and the other end of the bag filter is connected to an induced draft fan. A slag conveyor belt is installed below the slag discharge port. Although this device makes full use of existing equipment and significantly reduces dust pollution, achieving environmental benefits, the large particle filter screen accumulates a large amount of dust after prolonged use, clogging the mesh and hindering dust collection. Ultimately, this reduces the dust collection efficiency and effectiveness, thus requiring improvement. Summary of the Invention

[0004] The main objective of this invention is to provide a dust collection device for power plants, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a power plant dust collection device includes a bag filter 1 and a protective filter 3. A dust collection pipe 2 is fixedly installed on the bag filter 1, and a connecting assembly 4 is fixedly sleeved on the dust collection pipe 2. The connecting assembly 4 consists of a mounting cover 7, a U-shaped bracket 8, a support base ring 9, and support springs 10. There are two U-shaped brackets 8, which are symmetrically fixedly installed on the outer wall of the mounting cover 7. The support base ring 9 is fixedly installed on the inner wall of the mounting cover 7. There are several support springs 10, which are all fixedly installed on the upper end of the support base ring 9. The protective filter 3 is movably installed inside the mounting cover 7, and the protective filter 3 is located on the upper end of several support springs 10. Two impact components 5 are symmetrically installed on the connecting assembly 4 and above the protective filter 3. The impact components 5 consist of a servo motor 14 and an impact block 15. The impact block 15 is fixedly installed on the output shaft of the servo motor 14. The bag filter 1 is connected to a fan 6 through a pipe.

[0021] In use, the connecting component 4 is fixed above the slag discharge port of the slag cooler. When the slag cooler discharges slag, the blower 6 can be started, so that the dust generated by the slag discharge will be sucked into the connecting component 4. Then the dust will pass through the mesh of the protective filter screen 3, and then the dust will enter the bag filter 1 through the dust suction pipe 2. Finally, the dust will be collected by the bag filter 1, and the air filtered by the bag filter 1 will be discharged by the blower 6. When the dust passes through the mesh of the protective filter screen 3, some of it will adhere to the protective filter screen 3. Therefore, in order to avoid the dust from being trapped, the dust must be removed from the filter screen 3. If the mesh of the protective filter 3 is clogged with dust, the protective filter 3 can be cleaned periodically using the connecting component 4 and the striking component 5. The method is as follows: first, the servo motor 14 drives the striking block 15 to rotate. The rotating striking block 15 will strike and push the protective filter 3. At the same time, under the force of the supporting spring 10, the protective filter 3 will also be pushed upward and reset. During this process, the protective filter 3 will vibrate, and under the action of this vibration, the dust on the protective filter 3 will be shaken off. At this time, the cleaning of the protective filter 3 is completed.

[0022] Therefore, by setting up the connecting component 4 and the striking component 5, and installing the protective filter 3 inside the connecting component 4, the protective filter 3 can be cleaned regularly using the connecting component 4 and the striking component 5. This prevents a large amount of dust from adhering to the protective filter 3, ensuring that dust can always pass through the mesh of the protective filter 3 and be collected by the bag filter 1. Ultimately, this ensures that the bag filter 1 can maintain good dust collection efficiency and effect.

[0023] Specifically, the protective filter 3 consists of an annular frame 16 and a filter body 17. The filter body 17 is fixedly installed on the inner wall of the annular frame 16, which is fixedly installed on the upper end of the support spring 10. The upper side wall of the mounting cover 7 on the connecting assembly 4 has mounting holes 13. Two first through holes 11 are symmetrically opened on the side wall of the mounting cover 7. The mounting cover 7 is fixedly fitted onto the suction pipe 2 through the mounting holes 13. The support base ring 9 is located on the lower inner wall of the mounting cover 7. Several support springs 10 are arranged in a ring on the upper end of the support base ring 9. A second through hole 12 is opened on the U-shaped bracket 8, and the second through hole 12 is coaxial with the first through hole 11. The servo motor 14 on the striking assembly 5 is fixedly installed at one end of the U-shaped bracket 8. The output shaft of the servo motor 14 is rotatably installed in the first through hole 11 and the second through hole 12. Inside the through hole 12, the striking block 15 is located inside the mounting cover 7. The striking block 15 is also located at the upper end of the annular frame 16. The striking block 15 is triangular in shape. When the servo motor 14 drives the striking block 15 to rotate, the protruding corner of the striking block 15 will strike and push the protective filter 3. The protective filter 3 will be pushed downward at this time. At this time, the support spring 10 below the protective filter 3 will be compressed. As the striking block 15 rotates, when the protective filter 3 loses the compression of the protruding corner of the striking block 15, under the elastic force of the support spring 10, the protective filter 3 will move upward in the mounting cover 7. Then, as the striking block 15 rotates, the protruding corner of the striking block 15 will strike and push the protective filter 3 again. This cycle repeats, and the protective filter 3 will vibrate at a distance, thereby shaking off the dust attached to it.

[0024] Preferably, the number of support springs 10 is 6 or 8, and the support springs 10 are evenly distributed on the upper end of the support base ring 9.
