Description
Technical Field
[0001] The present application relates to the technical field related to dust removal machinery, and in particular to a high-efficiency and energy-saving control device for electric dust removal in power plants. Background Art
[0002] The electrostatic precipitator is a dust removal device that charges dust particles during the ionization process of dust-containing gas through a high-voltage electric field, and deposits dust particles on the dust collector under the action of the electric field force, thereby separating dust particles from dust-containing gas. Specifically, when dust particles in the flue gas pass through a high-voltage electrostatic field, they collide with positive and negative ions and electrons between electrodes and become charged (or become charged during ion diffusion movement). Dust particles carrying electrons and ions move toward the opposite electrode under the action of the electric field force and accumulate on the opposite electrode. The dust on the electrode falls into the ash collection hopper through vibration and other means, so that the flue gas passing through the electrostatic precipitator is purified.
[0003] However, in traditional electrostatic precipitator systems, the cleaning operation of the dust collecting plates often relies on preset time intervals or fixed monitoring thresholds. This non-intelligent cleaning mechanism has significant drawbacks, especially in terms of energy-saving control. Specifically, when the dust accumulated on the dust collecting plates has not reached a critical weight that is sufficient to affect its dust removal efficiency or requires immediate removal, frequent knocking and cleaning will not only cause unnecessary energy consumption, but may also accelerate equipment wear and shorten its service life. On the contrary, if the cleaning is not timely, the dust removal efficiency may be reduced due to excessive dust accumulation, and even equipment failure may be caused. Therefore, how to accurately judge the accumulation state of dust on the dust collecting plates and realize on-demand and efficient cleaning control has become an important issue that needs to be urgently solved in current electrostatic precipitator technology. Utility Model Content
[0004] The present application proposes a high-efficiency and energy-saving control device for electrostatic precipitators in power plants, which has the advantage of timely knocking and cleaning, and is used to solve the problem of frequent knocking leading to increased energy consumption and shortened service life of the device mentioned in the above background technology.
[0005] To achieve the above object, the present application adopts the following technical solutions: A high-efficiency and energy-saving control device for electric dust removal in a power plant, comprising: a dust removal box with a dust removal chamber formed inside, a gas supply pipe fixed at one end for inputting flue gas through a fan, and an exhaust pipe fixed at the other end for discharging the purified flue gas to the outside; a corona electrode seat fixed on the inner top of the dust removal box; a dust collecting electrode seat arranged inside the dust removal box on both sides of the corona electrode seat; a fixed seat fixed inside the dust removal box, and an adjusting intermediate seat is movably installed inside the fixed seat, and the adjusting intermediate seat and the dust collecting electrode seat are connected by a transmission block, and an adjusting spring is connected between the inner sides of the adjusting intermediate seat and the fixed seat; a driving motor fixed at the end of the dust removal box, and a transmission rod extending into the dust removal box is fixedly installed on the output shaft of the driving motor, a connecting sleeve frame is installed on the outside of the transmission rod, and a vibration ash hammer is hinged on the outer surface of the connecting sleeve frame.
[0006] Further, there are two transmission rods, and belt pulleys are fixedly installed at the ends of the two transmission rods, and the belt pulleys are connected by a transmission belt.
[0007] Further, a travel switch is fixedly installed inside the fixed seat, and the travel switch, the driving motor and the power supply are connected in series.
[0008] Further, a limit head is movably installed at the end of the adjusting intermediate seat, and a limit spring is connected between the limit head and the adjusting intermediate seat, and a stop tooth seat is fixedly installed inside the fixed seat.
[0009] Further, the cross-sectional shape of the stop tooth seat is a right triangle.
[0010] Further, an outer support frame is fixed at the bottom of the fixed seat, and a detection slider is movably installed at the top of the outer support frame. The connecting sleeve frame is movably sleeved on the outside of the transmission rod, and a rotating top rod is movably installed inside the connecting sleeve frame. A separating top spring is connected between the rotating top rod and the connecting sleeve frame. A driving gear located inside the connecting sleeve frame is fixedly installed on the outside of the transmission rod, and an adjusting top head located above the detection slider is fixedly installed at the bottom of the adjusting intermediate seat.
[0011] Further, the shape of the rotating top rod is "T" shaped.
[0012] The utility model has the following beneficial effects:
[0013] A high-efficiency and energy-saving control device for electric dust removal in a power plant provided by the present application connects an adjusting spring to the top of the dust collecting electrode seat. This spring not only serves as a weight detection element but also plays a key role in triggering the ash cleaning process. As the dust collecting electrode seat effectively adsorbs soot particles, its cumulative weight gradually increases. When this weight reaches the preset ash cleaning threshold, the dust collecting electrode seat automatically pulls down the adjusting intermediate seat through a linkage mechanism, thereby applying pressure to the adjusting spring and compressing it to a specific degree.
[0014] This compression action immediately triggers the built-in travel switch, and the closure of the travel switch quickly activates the drive motor. The drive motor drives the ash-removing hammer to perform a rotational motion through the connecting sleeve frame with efficient transmission. During the rotation of the ash-removing hammer, it periodically strikes the dust collecting electrode seat, effectively shaking off and removing the soot particles adhering to the dust collecting electrode seat.
[0015] Since the ash cleaning action is automatically triggered only when the weight of the dust collecting electrode seat reaches the threshold, the drive motor does not need to run continuously, thus significantly reducing the energy consumption and improving the overall energy efficiency. On the other hand, through a timely and appropriate knocking strategy, it effectively avoids the possible wear or damage of the dust collecting electrode seat due to long-term continuous knocking, significantly extends the service life of the equipment, and reduces the maintenance cost.

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.
[0027] Embodiment 1
[0028] Please refer to Figure 1 and Figure 2 It can be seen that the dust removal box 1 is fixed at the applied position by a bottom steel bracket. An air supply pipe 101 is fixedly installed at one end of the dust removal box 1. The air supply pipe 101 is connected to a fan, so that the flue gas generated by the power plant is input into the dust removal chamber 100 opened inside the dust removal box 1. From Figure 2 it can be seen that a plurality of corona electrode seats 4 are fixedly installed on the inner top of the dust removal box 1. In this application, four are taken as an example, and the actual number applied is not limited to this. It can be reasonably arranged according to actual needs and the actual application environment. The plurality of corona electrode seats 4 are equidistantly arranged on the inner top of the dust removal box 1. A dust collecting electrode seat 5 is movably installed on both sides of the corona electrode seat 4 inside the dust removal box 1. When the flue gas passes through the corona electrode seat 4, the dust particles are charged and are easily adsorbed by the dust collecting electrode seat 5. After the flue gas in the dust removal chamber 100 is purified, it is output from the exhaust pipe 102 fixed at the other end of the dust removal box 1 to the next process (the next process is generally a wet desulfurization system for desulfurization treatment, which can be adjusted according to actual needs).
[0029] In order to clean the dust particles adsorbed on the dust collecting electrode seat 5, referring to Figure 2 it can be seen that a plurality of dust collecting electrode seats 5 are arranged inside the dust removal box 1. The number of the dust collecting electrode seats 5 is also arranged as required. In this application, five are taken as an example. The dust collecting electrode seats 5 are arranged on both sides of the corona electrode seat 4. When the dust particles are charged by the corona electrode seat 4, they can be quickly adsorbed by the dust collecting electrode seat 5, so as to accelerate the effect of dust cleaning. Referring to Figure 3 and Figure 4It can be seen that there is a fixed seat 6 on the inner side of the dust removal box 1, which is fixedly connected by bolts, and an adjustable middle seat 11 is movably installed inside the fixed seat 6. The adjustable middle seat 11 can only reciprocate up and down along the inside of the fixed seat 6. The adjustable middle seat 11 and the dust collecting pole seat 5 are connected by a transmission block 7. Specifically, the upper and lower ends of the transmission block 7 are fastened to the top of the dust collecting pole seat 5 and the bottom of the adjusting middle seat 11 by bolts. At the same time, an adjusting spring 110 is connected between the adjusting middle seat 11 and the inner side of the fixed seat 6. Under normal conditions, the adjusting middle seat 11 is forced to move upward by the elastic force of the adjusting spring 110, and the dust collecting pole seat 5 is pulled upward by the transmission block 7. As time goes by, the amount of dust adsorbed on the surface of the dust collecting pole seat 5 increases, forcing the weight of the dust collecting pole seat 5 to increase. The strength of the dust collecting pole seat 5 dragging the transmission block 7 and pulling the adjusting middle seat 11 downward increases, causing the adjusting middle seat 11 to have a tendency to compress the adjusting spring 110 downward. Figure 2 and Figure 3 It can be seen that, since there are multiple dust collecting pole seats 5, the top of each dust collecting pole seat 5 is connected to a corresponding transmission block 7 and an adjusting intermediate seat 11.
[0030] The end of the dust removal box 1 is provided with a driving motor 2 fixedly mounted by a motor bracket, and a transmission rod 301 extending into the interior of the dust removal box 1 is fixedly mounted on the output shaft of the driving motor 2. Figure 4 It can be seen that a connecting sleeve 9 is installed on the outside of the transmission rod 301, and a vibrating hammer 10 is hinged on the outside of the surface of the connecting sleeve 9. When the driving motor 2 drives the transmission rod 301 to rotate, the connecting sleeve 9 drives the vibrating hammer 10 to rotate, so that the dust collecting pole seat 5 close to the vibrating hammer 10 is knocked, and the smoke adsorbed on the dust collecting pole seat 5 can be removed by knocking. Since the dust collecting pole seats 5 are distributed on both sides of the corona pole seat 4, in order to realize the knocking and cleaning of all the dust collecting pole seats 5, combined with Figure 2 It can be seen that there are two transmission rods 301, and the ends of the two transmission rods 301 are fixedly mounted with pulleys 3, and the pulleys 3 are connected by a transmission belt 300. In actual application, since the driving motor 2 drives one transmission rod 301 to rotate, the transmission of the pulley 3 and the transmission belt 300 forces the two transmission rods 301 to rotate synchronously, so that the connecting sleeve 9 and the vibrating hammer 10 fixed on the transmission rod 301 can knock and vibrate all the dust collecting pole seats 5.
[0031] In order to start the drive motor 2 in time, Figure 4 and Figure 5It can be seen that a travel switch 13 is fixedly installed inside the fixed seat 6. The travel switch 13, the drive motor 2, and the power supply are connected in series. The travel switch 13 is used to control the start and stop of the drive motor 2, and the travel switch 13 is installed below the adjustment intermediate seat 11. When the dust collecting electrode seat 5 pulls the adjustment intermediate seat 11 downward, the adjustment intermediate seat 11 will eventually contact the travel switch 13 below, causing the drive motor 2 to start, and finally realizing the knocking function described above.
[0032] During actual application, under normal conditions, the surface of the dust collecting electrode seat 5 is relatively clean. The adjustment intermediate seat 11 is pushed upward by the adjustment spring 110. The adjustment intermediate seat 11 uses the transmission block 7 to pull the dust collecting electrode seat 5 upward. At this time, the travel switch 13 is not squeezed by the adjustment intermediate seat 11, and the drive motor 2 stops working.
[0033] The flue gas output from the power plant is input into the air supply pipe 101 by the fan. When the flue gas passes through the dust removal chamber 100, the corona electrode seat 4 is used to charge the dust particles. The charged dust particles are adsorbed by the dust collecting electrode seat 5, and the purified dust is output outward from the exhaust pipe 102.
[0034] As time goes by, the dust particles adsorbed on the surface of the dust collecting electrode seat 5 increase continuously, resulting in an increase in the weight of the dust collecting electrode seat 5. The dust collecting electrode seat 5 pulls the adjustment intermediate seat 11 downward with a greater intensity through the transmission block 7, forcing the adjustment intermediate seat 11 to compress the adjustment spring 110 downward. When the adjustment intermediate seat 11 contacts the travel switch 13, the travel switch 13 starts and causes the drive motor 2 to start working. The drive motor 2 drives the transmission rod 301 to rotate, and the transmission rod 301 drives the ash vibrating hammer 10 on the connecting sleeve frame 9 to knock on the dust collecting electrode seat 5, causing the dust adsorbed on the dust collecting electrode seat 5 to fall to the bottom of the dust removal chamber 100. After the dust particles on the dust collecting electrode seat 5 are removed, the weight of the dust collecting electrode seat 5 decreases. Under the elastic force of the adjustment spring 110, the adjustment intermediate seat 11 moves upward. When the adjustment intermediate seat 11 moves away from the travel switch 13, the adjustment intermediate seat 11 releases the extrusion on the travel switch 13, the travel switch 13 disconnects, and the drive motor 2 stops working. This ensures that after the cleaning of the dust collecting electrode seat 5 is completed, the drive motor 2 will not start continuously, thereby reducing energy consumption.
[0035] Embodiment 2
[0036] On the basis of Embodiment 1, a further improvement is made. Please refer to Figure 5 and Figure 6 It can be seen that a limit head 12 is movably installed at the end of the adjustment intermediate seat 11, and a limit spring 120 is connected between the limit head 12 and the adjustment intermediate seat 11. Due to the elastic force of the limit spring 120, the top end of the limit head 12 always abuts against the inside of the fixed seat 6, and a fillet is provided at the top end; correspondingly, a stop tooth seat 600 is fixedly installed inside the fixed seat 6. Combining Figure 6It can be seen that the cross-sectional shape of the stop tooth seat 600 is a right triangle, and the right-angled side of the stop tooth seat 600 is smaller than the arc angle at the end of the limit head 12.
[0037] Combined with the content in the first embodiment, it can be known that when the weight of the dust collecting electrode seat 5 increases due to the increase of soot on its surface, it will force the adjusting intermediate seat 11 to press down the travel switch 13. However, after the connecting sleeve frame 9 drives the ash vibrating hammer 10 to strike the dust collecting electrode seat 5 once, the soot shaken off from the dust collecting electrode seat 5 will cause its own weight to be insufficient to suppress the elastic force of the adjusting spring 110, forcing the ash vibrating hammer 10 to stop striking before the dust collecting electrode seat 5 is completely cleaned. To solve such problems, the limit head 12 and the stop tooth seat 600 in the second embodiment provide a one-way resistance limiting function. Specifically, when the adjusting intermediate seat 11 drives the limit head 12 to move downward, combined with Figure 6 It can be seen that the limit head 12 passes through the inclined surface of the stop tooth seat 600 and squeezes the limit spring 120, forcing the limiting force for the adjusting intermediate seat 11 to move downward to be relatively small; when the ash vibrating hammer 10 on the connecting sleeve frame 9 strikes the dust collecting electrode seat 5, it will cause the weight of the dust collecting electrode seat 5 to increase, and the pressing intensity of the adjusting intermediate seat 11 downward increases. When the adjusting spring 110 pushes the adjusting intermediate seat 11 to move upward, the limit head 12 will abut against the right-angled side of the stop tooth seat 600. At this time, the intensity for the limit head 12 to cross over the stop tooth seat 600 relatively increases. As the connecting sleeve frame 9 drives the ash vibrating hammer 10 to continuously strike, the soot on the dust collecting electrode seat 5 is continuously cleared, and the intensity of the adjusting intermediate seat 11 pressing the adjusting spring 110 also continuously decreases. When the dust collecting electrode seat 5 meets the cleaning requirements, the elastic force of the adjusting spring 110 will force the adjusting intermediate seat 11 to drive the limit head 12 to cross over the stop tooth seat 600, causing the adjusting intermediate seat 11 to move upward and disengage from the travel switch 13. When the travel switch 13 stops working, the drive motor 2 also stops working.
[0038] Embodiment Three
[0039] On the basis of the second embodiment, a further improvement is made. Please refer to Figures 4 - 7It can be seen that there is an outer support frame 8 fixed by a connecting frame at the bottom of the fixed seat 6, and a detection slider 800 is movably installed at the top of the outer support frame 8. When the detection slider 800 moves downward to the limit, a complete circle is formed by the inner sides of the detection slider 800 and the outer support frame 8. The connecting sleeve 9 is movably sleeved outside the transmission rod 301, and a rotating ejector rod 15 is movably installed inside the connecting sleeve 9. The shape of the rotating ejector rod 15 is "T"-shaped, and a separating spring 150 is connected between the rotating ejector rod 15 and the connecting sleeve 9. According to the elastic force of the separating spring 150, the rotating ejector rod 15 always has a tendency to move away from the connecting sleeve 9; correspondingly, a driving gear 14 located inside the connecting sleeve 9 is fixedly installed on the outside of the transmission rod 301. When the driving gear 14 abuts against the outside of the driving gear 14, the transmission rod 301 can drive the connecting sleeve 9 to rotate according to the rotating ejector rod 15. The adjusting middle seat 11 is fixedly installed at the bottom with an adjusting ejector head 111 located above the detection slider 800. When the limiting head 12 moves downward and passes over the stop tooth seat 600, the adjusting ejector head 111 abuts against the detection slider 800 and moves downward to the limit, forcing a complete circle to be formed by the inner sides of the detection slider 800 and the outer support frame 8.
[0040] Specifically, when the dust collecting electrode seat 5 is relatively clean, the adjusting middle seat 11 is pushed upward by the elastic force of the adjusting spring 110. The adjusting middle seat 11 moves away from the travel switch 13, and, at the same time, the adjusting middle seat 11 drives the adjusting ejector head 111 to move away from the detection slider 800. Meanwhile, under normal conditions, the dust collecting cavity 100 moves downward by its own gravity, and the rotating ejector rod 15 on the connecting sleeve 9 is located below the detection slider 800. Due to the elastic force of the separating spring 150, the rotating ejector rod 15 abuts against the detection slider 800 and moves it upward, and the bottom of the rotating ejector rod 15 is not connected to the driving gear 14.
[0041] When the dust collecting electrode seat 5 causes the adjusting middle seat 11 to press the travel switch 13 due to an increase in the amount of soot, although the driving motor 2 will start, only the dust collecting electrode seat 5 with accumulated soot will push the adjusting middle seat 11 to press the adjusting ejector head 111, forcing the detection slider 800 to press the rotating ejector rod 15 downward until the rotating ejector rod 15 is connected to the driving gear 14. The connecting sleeve 9 is driven to rotate by the transmission rod 301 via the driving gear 14 and the rotating ejector rod 15, so that the connecting sleeve 9 knocks on the dust collecting electrode seat 5 through the ash vibrating hammer 10. As is known by common sense, the greater the load on the driving motor 2, the greater the energy consumption of the driving motor 2. Using this method can ensure that when the driving motor 2 drives the transmission rod 301 to rotate, only when the corresponding dust collecting electrode seat 5 has more dust, the connecting sleeve 9 will be driven to drive the ash vibrating hammer 10 to knock, while the other clean dust collecting electrode seats 5 do not need the connecting sleeve 9 to rotate. On the one hand, the load can be reduced and the energy consumption can be decreased; on the other hand, the ash vibrating hammer 10 is prevented from knocking on the clean dust collecting electrode seats 5, thereby reducing wear and damage and greatly improving the service life of the equipment.
