Abstract
Description
Technical Field
[0001] This utility model relates to the field of power distribution technology, and in particular to a power distribution panel for power output in an electrostatic precipitator. Background Technology
[0002] The core function of the power output distribution panel in an electrostatic precipitator is to precisely control the key components inside the precipitator (corona electrode and collecting electrode). When dust-laden flue gas is introduced into the dust collection chamber through the inlet horn, it first passes through the corona electrode area. Here, the corona electrode generates a high-intensity electric field, charging the dust particles in the flue gas, meaning the surface of the dust particles acquires an electric charge. Subsequently, under the influence of the electric field, these charged dust particles experience a force pointing towards the collecting electrode, causing them to move towards it and eventually deposit on the surface of the collecting electrode. This process achieves effective separation of dust and gas, ensuring the dust removal effect.
[0003] However, in practical applications, electrostatic precipitators do face some significant challenges. In particular, when a large amount of dust accumulates on the collecting plates, direct physical impact or rapping can prevent the dust from effectively detaching due to the continuous effect of the electric field. This not only reduces dust removal efficiency but may also lead to increased energy consumption and maintenance costs. Therefore, there is an urgent need for a dedicated power distribution device that can effectively and timely cut off the electrical power to the collecting plates during dust removal operations. Utility Model Content
[0004] This invention proposes a power distribution panel for power output in an electrostatic precipitator, which has the advantage of timely power on / off control, thereby solving the problem mentioned in the background art that dust is not easily detached from the dust collection plate during the dust removal process.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a distribution panel for power output in an electrostatic precipitator, comprising: a dust collection box, with an air inlet horn fixedly connected to one end and an exhaust horn installed at the other end; a corona electrode power supply fixedly installed on the top, with a corona electrode ring fixedly attached to the corona electrode power supply; a dust collection electrode power supply fixedly mounted on the surface of the dust collection box, with a guide slide fixedly installed inside the dust collection electrode power supply, and a distributor fixedly connected inside the dust collection electrode power supply; an electric contact plate mounted on the guide slide, the electric contact plate being electrically connected to the distributor via a wire; and a dust collection plate. Located in the dust collector box, and movably installed at the top with the dust collection electrode power supply, the top of the dust collection electrode plate has symmetrically arranged reset rods, and a reset push spring is set between the two reset rods; the power locking column is fixed to the end of the guide slide, and the power locking column is electrically connected to the power distributor through a wire; the dust vibrating motor is fixed on the dust collector box, and a transmission rod is fixedly installed on the output shaft of the dust vibrating motor. A mounting clamp seat is fixedly installed on the surface of the transmission rod, and a dust cleaning hammer is hinged to the outside of the mounting clamp seat; the reset tension spring is fixedly connected at the bottom to the top of the dust collection electrode plate, and at the top to the top of the inner side of the dust collector box.
[0006] Furthermore, there are three corona electrode power supplies, which are equidistantly distributed on the dust collection box.
[0007] Furthermore, the number of dust collection electrode power supply units is six, and the dust collection electrode plate is a corrugated plate.
[0008] Furthermore, the surface shape of the guide slide is a right-angled trapezoid, and there are two guide slides, which are symmetrically arranged on the inner side of the dust collection electrode power supply.
[0009] Furthermore, the power distributor activates the dust collection plate after being connected via two electrical contact plates.
[0010] Furthermore, the power distributor starts the ash-vibrating motor after being connected via two power-locking pins.
[0011] Furthermore, a spring is fixed to the outside of the dust removal hammer, and a double hammer ball is fixedly installed at the end of the spring.
[0012] This utility model has the following beneficial effects:
[0013] This utility model provides a power distribution panel for power output in an electrostatic precipitator. Its innovation lies in the ingenious design of an inclined plane as the guide surface of the guide slide. This design utilizes a physical principle: as the collecting electrostatic plate continuously adsorbs dust, its overall weight gradually increases. This increase in weight is triggered by a mechanical linkage mechanism, specifically, forcing the reset rod to slide down the inclined plane until it is precisely embedded in the power-connecting locking pin. This action triggers the electrical connection, allowing the dust-removing motor to be powered on and started.
[0014] Once the dust removal motor starts, it drives the dust removal hammers to perform regular tapping motions, directly impacting the dust collection plates and effectively shaking off the dust adsorbed on them. This dust removal process is crucial because it directly affects dust removal efficiency and the continuous high-efficiency operation of the equipment.
[0015] Most importantly, as the reset rod engages with the power-connecting lock pin and the dust-vibrating motor operates, the reset rod naturally moves away from the power-connecting slide plate, ensuring that the dust-collecting plate is de-energized during this dust-cleaning cycle. This design avoids interference from the electric field force during dust cleaning, making it easier for dust to separate from the plate, thereby significantly improving dust removal efficiency.
[0016] In summary, this distribution panel, through its intelligent mechanical and electrical linkage design, achieves timely control of power supply on and off, ensuring the effective execution of dust removal work and optimizing the overall performance of the electrostatic precipitator, ultimately achieving the goal of efficiently and accurately removing dust from the dust collection plates.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model is equipped with a dust collection electrode power supply 5 that can control the power supply, so that the dust collection electrode 8 can automatically disconnect the power during the dust cleaning process, and can resume dust adsorption after the dust cleaning is completed.
[0026] from Figure 1 As can be seen, the dust collector 1 has four support legs at the bottom, which allow it to be placed stably in the desired position. Furthermore, one end of the dust collector 1 has an air inlet horn 2, which is bolted to it. The air inlet horn 2 is typically connected to the outlet of the fan. This ensures that the dust-laden airflow can be delivered from the air inlet horn 2 into the interior of the dust collector 1. After the dust-laden air is purified inside the dust collector 1, it is finally discharged from the exhaust horn 3 fixed to the end of the dust collector 1.
[0027] Regarding specific dust purification processes, such as Figure 2 As shown, a corona electrode power supply 4 is fixedly installed on the top of the dust collector 1. Figure 2 It can be clearly determined that there are three corona electrode power supplies 4, which are equidistantly distributed on the dust collector 1. In actual arrangement, the corona electrode power supplies 4 can be directly connected to the input power supply, thereby controlling the supply of electrical energy to the corona electrode ring 7, which is tightly connected to them. The corona electrode ring 7 is generally located inside the dust collector 1. By using the corona electrode power supplies 4 to start the corona electrode ring 7, the dust-laden airflow can charge the dust as it passes through the corona electrode ring 7.
[0028] Furthermore, from Figure 2 It can also be seen that dust collection electrode power supplies 5 are fixedly installed on the surface of the dust collection box 1 near the end of the corona electrode power supply 4. Since there are three corona electrode power supplies 4, there are six corresponding dust collection electrode power supplies 5. Each dust collection electrode power supply 5 has a dust collection plate 8 installed at its bottom. The dust collection plate 8 is generally a corrugated metal plate. When the dust collection electrode power supply 5 energizes the dust collection plate 8 and starts working, it can adsorb the charged dust under the action of electric field force, thereby realizing the separation of dust particles and air in the dust-laden airflow, and finally completing the air purification work.
[0029] However, during prolonged use, the surface of the dust collection plate 8 accumulates dust, leading to a decrease in its dust adsorption strength. To achieve dust removal from the surface of the dust collection plate 8, from... Figure 4 It is evident that a guide slide 15 is fixedly installed inside the dust collector electrode power supply 5, and the surface shape of the guide slide 15 is a right-angled trapezoid. Furthermore, from... Figure 4 It can be seen that there are two guide slides 15, which are symmetrically arranged inside the dust collector power supply 5. Based on this, there is a distributor 14 inside the dust collector power supply 5, which is fastened with bolts. The distributor 14 can regulate the power output. Specifically, a power receiving plate 16 is fixedly installed on the inclined surface of the guide slide 15, and the power receiving plate 16 is electrically connected to the distributor 14 via a wire. The top of the dust collection plate 8 passes through the dust collector box 1 and is located inside the dust collection electrode power supply 5. Symmetrically arranged reset rods 18 are movably mounted on the top of the dust collection plate 8. A reset push spring 180 is provided between the two reset rods 18. In the initial state, the reset rods 18 are pushed outward by the elastic force of the reset push spring 180. Furthermore, the reset push spring 180 and the reset rods 18 respectively contact the contact plates 16, forcing the two contact plates 16 to connect. When current flows through the wires, a circuit is formed. During this process, the distributor 14 can connect to the dust collection plate 8 connected in series, causing the dust collection plate 8 to start working. The specific circuit is as follows: the input power is connected to the distributor 14. After the distributor 14 is connected through the two contact plates 16, it will start the dust collection plate 8. This circuit is a series circuit; it can be achieved simply by connecting the above-mentioned structures in series.
[0030] Furthermore, in order to ensure the cleaning intensity of the dust collection plate 8, from Figure 4 It can be seen that an electric locking pin 17 is fixedly installed at the end of the guide slide 15. The end of the electric locking pin 17 has an arc groove. When the reset rod 18 moves to the electric locking pin 17, the electric locking pin 17 is connected to the distributor 14 via a wire, thus using the reset rod 18 to energize the electric locking pin 17. After the electric locking pin 17 is energized, the ash-vibrating motor 6 connected in series with the electric locking pin 17 also works synchronously. Figure 2 As shown, when the dust removal motor 6 rotates, it causes the transmission rod 10, which extends into the inner cavity of the dust collector 1, to rotate synchronously. For the circuit layout, it is only necessary to connect the dust removal motor 6, the two power-connecting locking pins 17, the distributor 14, the reset push rod 18, and the reset push spring 180 in series.
[0031] Regarding the specific dust removal process, combined with Figure 2 and Figure 3It can be seen that a mounting clamp seat 11 is fixedly installed on the surface of the transmission rod 10, and the mounting clamp seat 11 is located on one side of the dust collection plate 8. A cleaning hammer 12 is hinged to the outside of the mounting clamp seat 11. When the transmission rod 10 drives the cleaning hammer 12 to rotate, the cleaning hammer 12 can strike the surface of the dust collection plate 8. The vibration from the striking can shake off the dust adsorbed on the dust collection plate 8, thereby completing the dust removal work on the surface of the dust collection plate 8.
[0032] In practical applications, such as Figure 2 As shown, a reset spring 9 is fixedly connected to the top of the dust collection plate 8, and the top of the reset spring 9 is fixedly connected to the top inner side of the dust collection box 1. Under the elastic pull of the reset spring 9, the relatively clean dust collection plate 8 is forced into an upward state. During this process, refer to Figure 4 As shown, after the dust collection plate 8 moves upward, it pushes the reset rod 18 to the outside of the contact plate 16. Under the elastic force of the reset push spring 180, the reset rod 18 moves upward along the contact plate 16, further enhancing the upward movement of the dust collection plate 8. At the same time, when the reset rod 18 is connected to the contact plate 16, the dust collection plate 8 connected in series with it will start to work.
[0033] When the external dust-laden airflow is delivered to the air intake horn 2 by the fan, the corona electrode power supply 4 controls the corona electrode ring 7 to start working, which causes the dust entering the inner cavity of the dust collector 1 to be charged. Under the action of the electric field force, the charged dust will move towards the dust collection plate 8 and eventually be adsorbed on the surface by the dust collection plate 8.
[0034] As working time increases, the amount of dust adsorbed on the surface of the dust collection plate 8 increases, resulting in an increase in the weight of the dust collection plate 8. During this process, the dust collection plate 8 moves downwards due to the increased weight, causing the reset rod 18 to move closer to the energizing lock post 17. During this process, the reset spring 9 is stretched. As the dust collection plate 8 continues to descend, the reset rod 18 eventually reaches the energizing lock post 17. Because the reset rod 18 connects the energizing lock post 17, the dust-vibrating motor 6, connected in series with the energizing lock post 17, starts working. The dust-vibrating motor 6 drives the transmission rod 10 to rotate, which in turn drives the cleaning hammer 12 on the mounting bracket 11 to strike the dust collection plate 8, thereby shaking off the dust adsorbed on the dust collection plate 8. Simultaneously, combined with... Figure 4 As shown, when the reset rod 18 connects the power lock pin 17, the reset rod 18 also moves away from the power contact plate 16, causing the power contact plate 16 to disconnect and the dust collection plate 8 to stop working. Combined with the continuous tapping of the dust collection plate 8 by the cleaning hammer 12, the dust collection plate 8 can be cleaned even when the power is off, greatly enhancing the efficiency of dust cleaning.
[0035] Subsequently, as the dust collecting plate 8 abuts against the arc groove at the end of the energizing lock post 17, there is a certain resistance between the reset rod 18 and the energizing lock post 17. With the continuous impact of the cleaning hammer 12 on the dust collecting plate 8, the dust on the plate gradually falls off, causing the weight of the dust collecting plate 8 to gradually decrease. Finally, under the elastic pull of the reset spring 9, the resistance between the reset rod 18 and the energizing lock post 17 is overcome, and the dust collecting plate 8 pushes the reset rod 18 upward until it contacts the energizing plate 16 again. When the energizing plate 16 is reconnected, the dust collecting plate 8 resumes its dust collecting operation. This cycle ensures that the dust collecting plate 8 can be switched on and off in a timely manner under the control of the distributor 14.
[0036] Based on this, in order to further enhance the cleaning intensity of dust on the surface of the dust collection plate 8, combined with Figure 3 It can be seen that a spring 130 is fixed to the outside of the dust removal hammer 12, and a secondary hammer ball 13 is fixedly installed at the end of the spring 130. When the mounting clamp seat 11 drives the dust removal hammer 12 to strike the dust collection electrostatic plate 8, the moving dust removal hammer 12 tends to stop moving due to the obstruction of the dust collection electrostatic plate 8 at the moment of striking the dust collection electrostatic plate 8. During the process of the dust removal hammer 12 striking the dust collection electrostatic plate 8, it will drive the secondary hammer ball 13 to move synchronously. When the dust removal hammer 12 stops moving momentarily, the secondary hammer ball 13 will cause the spring 130 to bend flexibly under the action of inertial force, and finally cause the secondary hammer ball 13 to strike the dust removal hammer 12, thereby realizing the secondary strike of the dust removal hammer 12 on the surface of the dust collection electrostatic plate 8, thereby enhancing the dust removal effect on the dust collection electrostatic plate 8.
