Description

Technical Field

[0001] The present application relates to the technical field related to electrostatic precipitators, and in particular to an environmentally friendly electrostatic precipitator filter cartridge cleaning device. Background Art

[0002] The electrostatic precipitator filter is a filter element used in an electrostatic precipitator. Its main function is to collect charged dust particles through its surface, thereby purifying the gas. During the electrostatic precipitator process, the dust particles are charged under the action of the electric field and adsorbed to the surface of the filter cartridge to form a dust layer. As the dust layer thickens, the dust removal efficiency of the filter cartridge will gradually decrease, so it needs to be cleaned regularly to maintain its dust removal performance.

[0003] However, as production continues, the dust layer attached to the surface of the filter cartridge will gradually thicken, resulting in an increase in the resistance of the airflow through the filter cartridge, which in turn affects the overall performance and dust removal efficiency of the dust collector. In order to maintain the efficient operation of the electrostatic precipitator, it is essential to regularly remove the dust layer on the filter cartridge. In actual operation, a vibration cleaning system is generally used to clean the filter cartridge. This system uses a mechanical device to apply high-frequency or low-frequency vibration to the filter cartridge to loosen and fall off the dust layer. However, in actual application, the impact force generated during the vibration process is often accompanied by the lifting of fly ash. These fine fly ash particles may not completely leave the dust removal system, but are re-suspended in the air with the disturbance of the airflow, and may even be carried to the vicinity of the exhaust port, thereby weakening the filtration effect to a certain extent and increasing the risk of secondary pollution. Utility Model Content

[0004] The present application proposes an environmentally friendly electrostatic precipitator filter cartridge cleaning device, which has the advantage of independent chamber cleaning and is used to solve the problem of fly ash generated by the filter cartridge being discharged with the airflow as mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: an environmentally friendly electrostatic dust filter cartridge cleaning device, comprising: a dust removal box, which uses an air inlet pipe to input dust airflow into the interior of the dust removal box, and the purified airflow is output from the exhaust pipe; a corona coil, which is arranged on the inner side of the air inlet pipe and is electrically controlled by a control console; a cleaning box, which is fixed to the bottom of the dust removal box, and a turntable is movably installed on the top of the cleaning box; a drive motor, which is installed to the inner side of the cleaning box, and its rotating shaft and the turntable are coaxially fixed; a dust collecting plate, which is movably arranged on the surface of the turntable, and a coil top seat is fixed on the top of the dust collecting plate; a power distribution seat, which is fixed on the top of the turntable, and the power distribution seat and the dust collecting plate are slidably connected; an arc contact seat, which is fixed on the inner side of the dust removal box; and a traction magnetic ring, which is fixed to the inner top of the dust removal box.

[0006] Furthermore, there are nine dust collecting plates, and the nine dust collecting plates are arranged at equal angles on the surface of the turntable.

[0007] Further, the electric arc seat is arc-shaped.

[0008] Further, a dust discharge valve is fixed at the bottom of the dust cleaning box.

[0009] Further, it further includes: an adjusting wheel, installed inside the turntable and located on the side of the dust collecting plate, and the adjusting wheel is in rolling connection with the outer side of the dust collecting plate; an intermediate wheel, installed inside the adjusting wheel, and a dust scraping plate is fixedly connected to the end of the intermediate wheel, and the rotating shaft of the dust scraping plate and the adjusting wheel are movably installed; a limiting rod, movably installed on the outer side of the intermediate wheel, and a limiting spring is arranged between the limiting rod and the intermediate wheel; an adjusting groove, opened inside the adjusting wheel.

[0010] Further, the cross-sectional shape of the dust scraping plate is an isosceles triangle.

[0011] The utility model has the following beneficial effects:

[0012] An environment-friendly electric dust removal filter cartridge cleaning device provided by the present application integrates an efficient dust cleaning cavity below the dust removal box. When a certain amount of dust accumulates on the dust collecting plate and reaches the cleaning condition, the dust collecting plate smoothly slides down to the lower dust cleaning cavity under the action of its own gravity.

[0013] A turntable is arranged in the dust cleaning cavity, and the turntable rotates under the drive of a driving device. As the turntable continues to rotate, the dust collecting plate on it also makes a circumferential movement. During this movement process, the dust particles firmly attached to the dust collecting plate are effectively thrown off under the action of centrifugal force and directly fall into a specific collection area in the dust cleaning cavity. This design ensures that the dust is concentrated and orderly processed, greatly reducing the generation and diffusion of fly ash.

[0014] Particularly importantly, a seal isolation is adopted between the dust cleaning cavity and the dust removal box to form an effective isolation barrier. This barrier not only prevents the fly ash particles that may be generated during the dust cleaning process from escaping into the dust removal box, but also ensures that the impact of the entire cleaning process on the environment is minimized. Therefore, even under strong dust cleaning actions, the gas cleanliness in the dust removal box can be maintained, avoiding the phenomenon of dust being discharged outward with the air flow, thereby realizing the high efficiency and environmental protection of the filter cartridge cleaning process.

Specific implementation manners

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0027] Embodiment 1

[0028] Please refer to Figure 1 and Figure 2As shown, the dust removal box 1 uses an air intake pipe 100 to input dust airflow into the interior of the dust removal box 1. Generally, the air intake pipe 100 is connected to a fan, and the fan is used as a driving force for the smoke airflow, so that the dust airflow is continuously transported to the interior of the dust removal box 1. A corona coil 7 is fixedly connected to the inner side of the air intake pipe 100, and a control console 2 for electrically controlling the corona coil 7 is fixedly connected to the top of the dust removal box 1. When the dust airflow passes through the corona coil 7, the dust particles collide with free electrons and negative ions and combine together, so that the dust particles are charged. This is achieved by the collision between the ions generated after the gas is ionized and the dust particles. When the charged dust particles pass through the dust collecting plate 8 set inside the dust removal box 1, the dust particles are deposited on the surface of the dust collecting plate 8 and form a thin dust layer. Finally, the purified airflow is discharged from the exhaust pipe 101 fixed on the side of the dust removal box 1.

[0029] When the dust collecting plate 8 is used for a long time, the thickness of dust accumulated on its surface will increase. In order to prevent the dust from flying around when cleaning it, Figure 2 and Figure 3 It can be seen that the bottom of the dust removal box 1 has a cleaning box 3 fixedly connected by a flange, and the top of the cleaning box 3 is movably installed with a turntable 5 located between the dust removal box 1 and the cleaning box 3, and the turntable 5 can separate the inner cavity of the dust removal box 1 from the inner cavity of the cleaning box 3. The inner side of the cleaning box 3 has a drive motor 4 fixed below the turntable 5 by a bracket, and the rotating shaft of the drive motor 4 is coaxially fixed with the turntable 5. The control console 2 is used to electrically control the drive motor 4 to realize the rotation of the turntable 5. Figure 4 It can be seen that the surface of the turntable 5 is movably arranged with a plurality of dust collecting plates 8 arranged at equal angles in the circumferential direction, and the dust collecting plates 8 can move up and down along the surface of the turntable 5. When the dust collecting plates 8 are placed in the inner cavity of the dust removal box 1, they are in a dust collecting state; when the dust collecting plates 8 are in the inner cavity of the dust cleaning box 3, they are in a cleaning state. Figure 8 It can be seen that the top of the dust collecting plate 8 is fixedly connected with a coil top seat 800, which can not only generate magnetism when powered on, but also after the dust collecting plate 8 completely enters the dust removal box 1 / dust cleaning box 3, the coil top seat 800 can be attached to the end face of the turntable 5 to ensure that the dust removal box 1 and the dust cleaning box 3 are isolated from each other.

[0030] For the connection of the coil top 800, Figures 3 - 5It can be clearly seen that a power distribution base 6 fixedly connected to the top of the turntable 5 and slidably connected to the dust collection plate 8. At the same time, an electric arc contact base 11 is fixedly connected to the inner side of the dust removal box 1 and located below the air inlet pipe 100. The electric arc contact base 11 is arc-shaped. When the turntable 5 drives the dust collection plate 8 to move between the electric arc contact base 11 and the power distribution base 6, the coil top base 800 is energized and generates magnetism due to the connection between the electric arc contact base 11 and the power distribution base 6. At the same time, the dust collection plate 8 is energized to perform dust collection work. Since the electric arc contact base 11 is located near the lower part of the air inlet pipe 100, the dust collection plate 8 starts to work after moving near the air inlet pipe 100. Similarly, when the dust collection plate 8 moves near the exhaust pipe 101, since the dust collection plate 8 is not connected to the electric arc contact base 11, the dust collection plate 8 does not work. Combining Figure 2 and Figure 3 It can be seen that a traction magnetic ring 12 is fixedly installed on the inner top of the dust removal box 1 and located above the dust collection plate 8. When the coil top base 800 is energized, it generates magnetism that attracts the traction magnetic ring 12, forcing the coil top base 800 to drag the dust collection plate 8 upward.

[0031] In practical applications, a fan is used to transport the smoke and dust airflow into the dust removal box 1 through the air inlet pipe 100. When the dust airflow passing through the corona coil 7 passes through the dust collection plate 8, the dust collection plate 8 adsorbs the dust on its surface.

[0032] The control console 2 controls the drive motor 4 to drive the turntable 5 to rotate continuously. When the turntable 5 drives the dust collection plate 8 to approach the electric arc contact base 11, since the electric arc contact base 11 and the power distribution base 6 connect the coil top base 800, the coil top base 800 generates magnetism that attracts the traction magnetic ring 12, and the dust collection plate 8 enters the interior of the dust removal box 1. At the same time, the dust collection plate 8 is energized to adsorb the dust. As the dust collection plate 8 passes through the air inlet pipe 100, it adsorbs the dust particles input from the air inlet pipe 100 into the dust removal box 1, and the purified airflow is output from the exhaust pipe 101.

[0033] As the turntable 5 rotates continuously, when the dust collection plate 8 moves away from the electric arc contact base 11, the coil top base 800 will also stop working. Combining Figure 3 It can be seen that the dust collection plate 8 drops into the interior of the ash cleaning box 3 under the action of its own gravity. At this time, since the dust collection plate 8 stops being powered, the adsorption force on the dust will also decrease. During the rotation of the turntable 5 driving the dust collection plate 8, the centrifugal force is used to throw the dust off the surface of the dust collection plate 8, and the dust finally accumulates at the bottom of the ash cleaning box 3. When it is necessary to clean the dust inside the ash cleaning box 3, only need to open the ash discharge valve 300 fixed at the bottom of the ash cleaning box 3.

[0034] Embodiment 2

[0035] On the basis of Embodiment 1, for further improvement, please refer to Figures 5 - 7As can be seen, an adjusting wheel 9 is movably installed inside the turntable 5 and is located at the side of the dust collecting plate 8. The adjusting wheel 9 is in rolling connection with the outer side of the dust collecting plate 8. One dust collecting plate 8 is connected to two adjusting wheels 9, and the two adjusting wheels 9 are symmetrically arranged on both sides of the dust collecting plate 8. When the dust collecting plate 8 moves up and down along the turntable 5, the dust collecting plate 8 drives the adjusting wheel 9 to rotate synchronously. An intermediate wheel 13 is movably installed inside the adjusting wheel 9, and a dust scraping plate 10 is fixedly connected to the end of the intermediate wheel 13. The rotating shaft of the dust scraping plate 10 is movably installed with the adjusting wheel 9. Since the dust scraping plate 10 and the intermediate wheel 13 are coaxially fixed, the dust scraping plate 10 and the intermediate wheel 13 rotate synchronously.

[0036] As can be seen from Figure 6 As can be seen, a plurality of limiting rods 14 are movably installed on the outer side of the intermediate wheel 13, and a limiting top spring 140 is arranged between the limiting rod 14 and the intermediate wheel 13. The top of the limiting rod 14 is tightly pressed against the inner side of the adjusting wheel 9 under the elastic force of the limiting top spring 140. The top of the limiting rod 14 is generally a sphere. Correspondingly, a plurality of adjusting grooves 900 are formed on the inner side of the adjusting wheel 9. When the sphere at the top of the limiting rod 14 abuts against the adjusting groove 900, the intermediate wheel 13 and the adjusting wheel 9 can rotate synchronously under a limited rotation force.

[0037] Combined with Figure 5 As can be seen, the cross-sectional shape of the dust scraping plate 10 is approximately an isosceles triangle. When the dust scraping plate 10 abuts against the surface of the dust collecting plate 8, the residual dust on the surface of the dust collecting plate 8 can be scraped off by using the tip of the dust scraping plate 10.

[0038] In the actual application process, as described in Embodiment 1, when the dust collecting plate 8 is near the air inlet pipe 100, since the electric arc contact seat 11 and the power distribution seat 6 connect the coil top seat 800, the dust collecting plate 8 performs the dust adsorption work. When the driving motor 4 drives the dust collecting plate 8 away from the electric arc contact seat 11 by using the turntable 5, the dust collecting plate 8 moves into the ash cleaning box 3 under its own gravity. During the downward movement, the dust collecting plate 8 causes the adjusting wheel 9 to rotate. The adjusting wheel 9 drives the intermediate wheel 13 to rotate synchronously through the limiting rod 14. Finally, the intermediate wheel 13 drives the dust scraping plate 10 to deflect, and the dust scraping plate 10 moves relatively away from the dust collecting plate 8, so that when the dust collecting plate 8 enters the ash cleaning box 3, the surface of the dust collecting plate 8 will not be scraped, and the generation of flying dust during the scraping process entering the interior of the dust removal box 1 is avoided.

[0039] When the dust collecting plate 8 is in the ash cleaning box 3 and rotates with the turntable 5, the dust on the surface of the dust collecting plate 8 is thrown into the ash cleaning box 3 under the influence of centrifugal force.

[0040] When the dust collecting plate 8 approaches the electric arc contact seat 11 again, under the magnetic attraction between the coil top seat 800 and the traction magnetic ring 12, the dust collecting plate 8 is forced to move into the dust removal box 1. During the movement, the dust collecting plate 8 also drives the adjusting wheel 9 to rotate. The adjusting wheel 9 is driven by the limiting rod 14 and the intermediate wheel 13, forcing the ash scraping plate 10 to deflect and stick to the surface of the dust collecting plate 8. When the dust collecting plate 8 moves upward, the ash scraping plate 10 scrapes the dust remaining on the surface of the dust collecting plate 8. As the dust collecting plate 8 continues to move upward, the adjusting wheel 9 attached to the surface of the dust collecting plate 8 stops rotating, and at the same time, the intermediate wheel 13 is restricted from rotating. When the adjusting wheel 9 rotates, the adjusting groove 900 is used to push the limiting rod 14 to compress the limiting spring 140, so that the intermediate wheel 13 no longer rotates with the adjusting wheel 9. Finally, the dust collecting plate 8 completely enters the dust removal box 1 and resumes the dust adsorption work again. This cycle is repeated to complete the dust adsorption and cleaning work.
