Description

Technical Field

[0001] This utility model relates to the technical field of smoke elimination and emission reduction equipment, and in particular to a smoke elimination and emission reduction equipment for environmental protection. Background Technology

[0002] Environmental protection smoke reduction and emission control equipment refers to a series of devices used to reduce the emission of smoke and harmful gases generated during industrial production and energy utilization. The purpose is to reduce the concentration of pollutants to meet environmental protection standards, reduce pollution to the atmospheric environment and harm to human health. Baghouse dust collectors are commonly used to purify flue gas. When dust-laden gas enters the dust collector, it passes through the filter bags under pressure difference, and dust particles are trapped on the surface of the filter bags. Therefore, the filter bags need to be cleaned. In existing technologies, air is blown into the inside of the filter bag through an air pipe to blow away the dust adhering to the outside of the filter bag. However, because filter bags are generally quite deep, the impact of the airflow on the dust on the outside of the filter bag is relatively small when it reaches the lower half of the filter bag, resulting in poor cleaning effect. Therefore, we propose an environmental protection smoke reduction and emission control device. Summary of the Invention

[0003] The purpose of this invention is to address the problem in the background art that, due to the generally large depth of filter bags, the airflow has less impact on the dust on the outside of the filter bag when it reaches the lower half of the filter bag, resulting in poor cleaning effect. This invention proposes an environmental protection smoke elimination and emission reduction device.

[0004] The technical solution of this utility model: A smoke elimination and emission reduction device for environmental protection, comprising a housing, and further comprising:

[0005] The smoke inlet pipe is installed on one side of the housing and the smoke outlet pipe is installed on the top of the housing;

[0006] Multiple sets of filter bags are fixedly installed inside the housing, and multiple sets of air tubes for cleaning the filter bags are slidably installed inside the housing, with the air tubes rotatably installed inside the filter bags.

[0008] Optionally, fixing blocks are fixedly installed on both sides of the housing, and a lead screw is rotatably installed between the fixing blocks and the top of the housing. A motor that drives the lead screw to rotate is fixedly installed on the top of the housing.

[0009] Optionally, each lead screw is threaded with a movable block, the main air pipe is fixedly installed between two sets of movable blocks, and multiple sets of branch pipes connected to the air pipe are fixedly installed at the bottom of the main air pipe. The air pipe and the branch pipes are rotatably connected, and the bottom of the air pipe is fixedly connected to an inclined pipe.

[0010] Optionally, a cover is fixedly installed on one side of the bottom of the main air pipe, a motor is fixedly installed inside the cover, and a drive gear is fixedly installed on the output shaft of the motor.

[0011] Optionally, a driven gear that meshes with the driving gear is fixedly installed at the top of the trachea, and the driven gears mesh with each other. The partition plate has multiple sets of through holes through which the trachea can pass.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention uses a rotating air pipe and an inclined pipe installed inside the filter bag to rotate and blow air into the filter bag, thereby cleaning the filter bag. At the same time, by raising and lowering the air pipe inside the filter bag, air can be blown to different depths inside the filter bag, achieving uniform air blowing and cleaning and ensuring the cleaning effect.

[0024] Example

[0025] like Figures 1 to 3As shown, the present invention proposes an environmental protection smoke elimination and emission reduction device, including a housing 1, a smoke inlet pipe 3 installed on one side of the housing 1 and a smoke exhaust pipe 2 installed on the top of the housing 1. The smoke exhaust pipe 2 is connected to an external exhaust fan. The smoke enters the housing 1 through the smoke inlet pipe 3. The filter bag 6 inside the housing 1 filters the smoke. The filtered smoke is discharged through the smoke exhaust pipe 2.

[0026] The housing 1 has a partition 8 fixedly installed inside, and the filter bag 6 is fixedly installed on the partition 8. The housing 1 has a main air pipe 9 connected to the air pipe 7 slidably installed inside, and the housing 1 has an air inlet pipe 4 connected to the main air pipe 9. The air inlet pipe 4 is connected to an external air source. Air enters the main air pipe 9 through the air inlet pipe 4, and then enters the air pipe 7 through the branch pipe 10, so that the air pipe 7 blows air onto the filter bag 6, causing the dust attached to the filter bag 6 to fall off the filter bag 6, thereby cleaning the filter bag 6.

[0027] In addition, multiple sets of filter bags 6 are fixedly installed inside the housing 1, and multiple sets of air pipes 7 for cleaning the filter bags 6 are slidably installed inside the housing 1. The air pipes 7 are rotatably installed inside the filter bags 6.

[0028] In this embodiment, fixing blocks 16 are fixedly installed on both sides of the housing 1. A lead screw 15 is rotatably installed between the fixing blocks 16 and the top of the housing 1. A motor 5 that drives the lead screw 15 to rotate is fixedly installed on the top of the housing 1. Each lead screw 15 is threadedly connected to a moving block 14. The main air pipe 9 is fixedly installed between two sets of moving blocks 14. Multiple sets of branch pipes 10 connected to the air pipe 7 are fixedly installed at the bottom of the main air pipe 9. The air pipe 7 is rotatably connected to the branch pipes 10. An inclined pipe 71 is fixedly connected at the bottom of the air pipe 7. The inclined pipe 71 is used to expand the blowing range of the air pipe 7. When the motor 5 is started, the lead screw 15 rotates, which drives the moving blocks 14 to move inside the housing 1. This causes the main air pipe 9 to rise and fall inside the housing 1, thereby causing the air pipe 7 and the inclined pipe 71 to rise and fall inside the filter bag 6. This allows the air pipe 7 and the inclined pipe 71 to blow air evenly onto the filter bag 6, thus improving the cleaning effect.

[0029] The main air pipe 9 has a cover 12 fixedly installed on one side of its bottom. A motor 13 is fixedly installed inside the cover 12. A drive gear 17 is fixedly installed on the output shaft of the motor 13. A driven gear 11 that meshes with the drive gear 17 is fixedly installed on the top of the air pipe 7. All driven gears 11 mesh with each other. Multiple sets of through holes are opened on the partition plate 8 for the air pipes 7 to pass through. When the motor 13 is started, the drive gear 17 rotates, which in turn drives the driven gears 11 that mesh with the drive gear 17 to rotate. Since the driven gears 11 mesh with each other, multiple sets of air pipes 7 and inclined pipes 71 rotate and blow air in the filter bag 6 at the same time, increasing the cleaning range.

[0030] The working principle of this embodiment is as follows: During operation, flue gas enters the housing 1 through the inlet pipe 3. The filter bag 6 inside the housing 1 filters the flue gas, and the filtered flue gas is discharged through the exhaust pipe 2. When it is necessary to clean the filter bag 6, air enters the main air pipe 9 through the inlet pipe 4, and then enters the air pipe 7 through the branch pipe 10 connected to the main air pipe 9. Air is blown onto the filter bag 6 through the air pipe 7 located inside the filter bag 6, causing the dust attached to the filter bag 6 to fall off the filter bag 6, thereby cleaning the filter bag 6. The motor 13 is started, causing the drive gear 17, which is fixedly connected to the output shaft of the motor 13, to rotate, thereby driving the... The driven gear 11 meshing with the driving gear 17 also rotates. Because the driven gears 11 mesh with each other, multiple sets of air pipes 7 and inclined pipes 71 rotate and blow air inside the filter bag 6, increasing the cleaning range. In addition, starting the motor 5 causes the lead screw 15 to rotate, driving the moving block 14 threaded to the lead screw 15 to move inside the housing 1. This causes the main air pipe 9 fixedly installed between the moving blocks 14 to rise and fall inside the housing 1, thereby causing the air pipes 7 and inclined pipes 71 to rise and fall inside the filter bag 6. This allows the air pipes 7 and inclined pipes 71 to blow air evenly onto the filter bag 6, improving the cleaning effect.

[0031] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
