A smart dust collection mechanism for an electrostatic precipitator and its application method

Abstract

This invention relates to the field of air pollution control technology and discloses an intelligent dust collection mechanism for an electrostatic precipitator and its usage method. To solve the problem of secondary dust generation caused by dust entering the dust collection box during ash discharge, multiple rotating gates are movably installed between the dust collection box and the dust collection hopper. During dust collection, the rotating gates are in a vertical state, and the spacing between the rotating gates ensures that dust falling from the dust collection components falls into the dust collection hopper for collection. During ash discharge, the rotating gates are in a horizontal state. By placing the rotating gates horizontally in sequence, the dust collection box and the dust collection hopper are sealed and separated, ensuring that dust inside the dust collection hopper will not enter the dust collection box during ash discharge and cause secondary pollution. Ultimately, the effect of sealed and separated ash discharge is achieved.

Description

Technical Field

[0001] This invention relates to the technical field of air pollution control, and in particular to an intelligent dust collection mechanism for an electrostatic precipitator and its usage method. Background Technology

[0002] The dust collection mechanism of an electrostatic precipitator mainly includes a rapping device and a dust hopper system. The rapping device mainly uses hammering or brushing to periodically remove the dust accumulated on the electrodes. After cleaning, the dust falls into the dust hopper, which is designed with an inclined discharge port to facilitate the collection and transportation of dust through a conveying system (such as a screw conveyor).

[0003] However, in practical applications, the collected dust is usually temporarily stored in the dust hopper. If the environment of the dust hopper is humid, causing the dust to clump together or attract each other due to van der Waals forces, abnormal situations can easily occur when the dust is discharged from the inclined ash discharge port. Specifically, the dust accumulates in an arch shape in the dust hopper, which blocks the ash discharge opening, preventing the dust hopper from discharging dust normally and thus affecting the operating efficiency of the entire electrostatic precipitator. To solve the problem of poor ash discharge, the dust is usually shaken. However, direct shaking will cause the originally accumulated dust to be stirred up, and this stirred-up dust will enter the dust collector with the airflow, causing secondary dust pollution. Secondary dust not only reduces the dust removal efficiency of the dust collector, but also increases the difficulty and cost of subsequent purification treatment, adversely affecting the stable operation of the entire dust removal system. Summary of the Invention

[0004] This invention proposes an intelligent dust collection mechanism for an electrostatic precipitator and its usage method, which has the advantage of sealed and separated dust discharge, thereby solving the problem of dust entering the dust collection box and causing secondary dust generation during dust discharge as mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent dust collection mechanism for an electrostatic precipitator, comprising: a dust collection box, internally equipped with a corona discharge assembly and a dust collection assembly controlled by a power supply and control components, for purifying dust-laden airflow; a dust cleaning assembly installed in the dust collection box capable of vibrating and cleaning the dust collection assembly, with dust collected by a dust collection hopper fixed at the bottom of the dust collection box; an auger installed on the inner bottom of the dust collection hopper, driven by a drive assembly, for outputting dust outwards; a switching combination rod coaxially and securely mounted on the output shaft end of the drive assembly; and a tilting gate, movably installed. When arranged vertically on the top inner side of the ash collection hopper, the dust collector box and the ash collection hopper are connected. The drive guide rod is movably installed in the ash collection hopper, and a gate closing rod is installed on the top of the rod on one side of the flip gate. Connecting arms are fixedly installed at both ends of the drive guide rod. Bolts that abut against the side of the switching combination rod are threaded to the side of the connecting arm. When the drive assembly drives the switching combination rod to rotate, the connecting arm drives the gate closing rod to move through the drive guide rod. The gate closing rod pushes the flip gate to a horizontal position and seals the dust collector box and the ash collection hopper, so that when the dust collector box collects ash, the ash collection hopper can discharge ash outwards simultaneously.

[0006] Furthermore, a torque limiting component is fixedly installed on the outside of the ash collection hopper. The output end of the torque limiting component is coaxially fastened to the auger, and the input end of the torque limiting component is fixedly connected to the drive component.

[0007] Furthermore, the middle part of the switching combination rod is a threaded part, and elliptical truncated cylindrical blocks are respectively set at both ends of the threaded part.

[0008] Furthermore, a valve core is movably installed on one side of the ash collection hopper. The valve core is movably installed with the connecting arm. A valve push spring is connected between the valve core and the ash collection hopper. The valve core is used to block the ash discharge port of the ash collection hopper.

[0009] Furthermore, a scraper blade is securely mounted at the bottom of the drive guide rod, and the scraper blade is slidably connected to the inner side of the ash collection hopper.

[0010] Furthermore, a position detection disc located on the outer side of the dust collection hopper is fixedly installed at the end of the rotating shaft of the tilting gate, and a detection switch is fixedly installed on the side of the dust collection box. The detection switch is electrically connected to the power supply and control components.

[0011] Furthermore, a guide return spring is connected between the valve core and the connecting arm.

[0012] Furthermore, a detection web is installed on the flip gate.

[0013] Furthermore, a locking groove is provided at the end of the valve core, and a locking notch is provided at the end of the auger shaft. The locking notch is inserted into the locking groove to restrict the rotation of the auger.

[0014] A method for using an intelligent dust collection mechanism in an electrostatic precipitator includes the following steps:

[0015] S1. Under normal conditions, the gate top rod and the flip gate are detached. The flip gate is in a vertical position under its own gravity. After the dust removal component knocks on the dust collection component, the shaken dust falls into the dust collection hopper.

[0016] S2. When dust removal is required, the drive component is rotated by controlling the power supply and control components.

[0017] S3. When the drive component rotates, the switching combination rod drives the connecting arm to move to the left.

[0018] S4. The connecting arm drives the gate top rod to move to the left through the drive guide rod, so that the gate top rod touches the bottom of the flip gate plate, switching the flip gate plate from the vertical state to the horizontal placement state, sealing and separating the dust collection box and the ash collection hopper, so that the dust collection box can continue to collect dust and the ash collection hopper can simultaneously perform ash discharge.

[0019] The present invention has the following beneficial effects:

[0020] This invention provides an intelligent dust collection mechanism for an electrostatic precipitator and its usage method. The dust collection mechanism mainly includes a dust collection box, a dust collection hopper, and multiple tilting gates movably installed between the two. During the dust collection stage, the tilting gates are in a vertical state. At this time, the adjacent tilting gates can ensure that the dust falling from the dust collection assembly passes smoothly and falls into the dust collection hopper for centralized collection.

[0021] When ash removal is required, the drive gate rotates around its axis, switching it to a horizontal position. In the horizontal position, the gates form a continuous and complete sealed barrier, completely separating the dust collector and the ash hopper. This sealed separation design has multiple important advantages: Firstly, it effectively prevents dust inside the ash hopper from being stirred up during ash removal due to airflow disturbances or mechanical vibrations, avoiding dust entering the dust collector and thus preventing secondary pollution. This ensures a clean working environment inside the dust collector, improving dust removal efficiency and extending equipment lifespan. Secondly, the sealed separation provides a relatively independent and stable space for subsequent ash removal operations, making the ash removal process more controllable and efficient.

[0022] Furthermore, after the flipping gate completes the sealing and separating action, the drive guide rod pushes the scraper blade along the inner side of the ash collection hopper in a reciprocating motion according to a preset pattern. This reciprocating scraping action has a dual function: firstly, the scraper blade can effectively scrape off stubborn dust clumps adhering to the inner wall of the ash collection hopper, separating them from the inner wall and gradually gathering them near the ash discharge port as the scraper blade moves, facilitating subsequent centralized discharge; secondly, the continuous reciprocating motion of the scraper blade on the inner side of the ash collection hopper can break up any arched structure that dust may form inside the ash collection hopper. In traditional ash collection mechanisms, dust easily forms arched accumulations near the ash discharge port due to its own gravity, interparticle interaction forces, and the shape of the ash collection hopper, leading to problems such as poor ash discharge or even blockage. The reciprocating motion of the scraper blade in this invention can disrupt the stability of this arched structure, keeping the dust in a loose state, thereby ensuring that the dust inside the ash collection hopper can be smoothly discharged through the ash discharge port, ultimately achieving a highly efficient ash discharge effect.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1, please refer to Figure 1 and Figure 3 It can be seen that the dust-laden airflow, after being conveyed by the fan, enters through the air inlet horn fixedly installed on the side of the dust collector 1, and after being purified inside the dust collector 1, it is output from the exhaust horn fixedly installed on the other side of the dust collector 1. Figure 10 The state shown.

[0038] Multiple corona discharge units 101 and dust collection units 102 are installed inside the dust collector 1. Both the corona discharge units 101 and the dust collection units 102 are powered and regulated by a power supply and control unit 2 fixedly installed on the top of the dust collector 1. When the dust-laden airflow passes through the corona discharge units 101, it charges the dust particles. The charged dust particles move towards the dust collection units 102 under the influence of the electric field and are eventually adsorbed onto the dust collection units 102. As the dust collection units 102 continuously capture and adsorb dust, the thickness of the dust layer on their collection surface increases. To facilitate cleaning of the dust layer, [the dust collection unit is used to...]. Figure 3 As can be seen, a dust removal component 103 is movably installed inside the dust collector 1, located on one side of the dust collection component 102. The dust removal component 103 is generally driven by a motor, which rotates the dust removal component 103, thereby periodically tapping the dust collection component 102. The dust shaken off the dust collection component 102 eventually falls into the dust collection hopper 3 fixedly connected to the bottom of the dust collector 1 for collection.

[0039] in accordance with Figures 3-5It is evident that the bottom inner side of the ash collection hopper 3 has a certain inclination angle, and an auger 13 is movably installed on the bottom inner side of the ash collection hopper 3. Based on the inclination of the inner side of the ash collection hopper 3, the collected dust particles can be concentrated and conveyed to the auger 13. For driving the auger 13, a torque limiting component 5 is fixedly installed on the outer side of the ash collection hopper 3. The output end of the torque limiting component 5 is coaxially and tightly fixed to the auger 13, and the input end of the torque limiting component 5 is fixedly connected to the drive component 4. The drive component 4 is preferably a geared motor. The drive component 4 drives the torque transmission through the torque limiting component 5, ultimately realizing the rotation of the auger 13 and completing the ash discharge action. More details can be found from... Figure 4 As can be seen, the torque limiting component 5 mainly includes two transmission discs and a transmission rod for transmitting torque between the two discs. One transmission disc shaft is fixedly connected to the auger 13, and the other is fixedly connected to the output end of the drive component 4. A spring pushes the transmission rod, thereby achieving torque transmission between the two transmission discs. When the resistance of the auger 13 is too high, the torque limiting component 5 can prevent the drive component 4 from being damaged due to excessive load.

[0040] In practical applications, to prevent dust from being stirred up in the dust collection hopper 3 during the screed 13's ash discharge process from re-entering the dust collector 1 and causing secondary pollution, and to address the issue of airflow from inside the dust collector 1 being blown out through the ash discharge port of the dust collection hopper 3, from... Figure 3 and Figure 4 It can be seen that a rotating gate 16 is movably installed on the top inner side of the dust collection hopper 3, located between the dust collector 1 and the dust collection hopper 3. There are multiple rotating gates 16, and they are arranged horizontally and equidistantly on the top inner side of the dust collection hopper 3. Under normal conditions, since one end of the rotating gate 16 is movably connected to the inner side of the dust collection hopper 3, it is in a vertical position under the influence of gravity. During this process, the interior of the dust collector 1 and the interior of the dust collection hopper 3 are interconnected. When the dust removal assembly 103 vibrates and cleans the dust collection assembly 102, the dust falling off the dust collection assembly 102 can fall into the inner cavity of the dust collection hopper 3.

[0041] Moreover, combined Figure 4 and Figure 6It can be seen that a drive guide rod 10 is movably installed in the middle of the inner side of the ash collection hopper 3, and both ends of the drive guide rod 10 extend from the side of the ash collection hopper 3. A gate-closing rod 14, bolted to the top of the drive guide rod 10 and located on one side of the tilting gate 16, is also present. When the drive guide rod 10 moves horizontally along the inner side of the ash collection hopper 3, it drives the gate-closing rod 14 to move, and the gate-closing rod 14 pushes the tilting gate 16 from a vertical to a horizontal position. After all the tilting gates 16 have changed from a vertical to a horizontal position, a sealed separation can be achieved between the dust collector 1 and the ash collection hopper 3. At this time, ash collection can still be carried out normally in the inner cavity of the dust collector 1, while ash discharge can be carried out simultaneously in the ash collection hopper 3, ensuring that the equipment can perform ash discharge operations without stopping the machine. In detail, the drive of the drive guide rod 10 is as follows... Figures 4-6 It can be seen that a switching combination rod 7 is coaxially and securely mounted on the output shaft end of the drive assembly 4, and the middle part of the switching combination rod 7 is threaded. Correspondingly, a connecting arm 8 is fitted on the outer side of the switching combination rod 7, and the top of the connecting arm 8 is fixedly connected to the drive guide rod 10. A bolt 9 is threadedly connected to the side of the connecting arm 8 and abuts against the threaded part. When the switching combination rod 7 rotates, the connecting arm 8 can drive the drive guide rod 10 to move, thereby controlling the opening and closing of the flip gate 16 according to the gate closing rod 14.

[0042] In practical applications, under normal conditions, the gate top rod 14 and the tilting gate 16 are disengaged. The tilting gate 16 is in a vertical position under its own weight. After the dust removal component 103 strikes the dust collection component 102, the dislodged dust can fall smoothly into the dust collection hopper 3. When dust removal is required, the drive component 4 is rotated according to the power supply and control component 2. At this time, the switching combination rod 7 drives the connecting arm 8 to move to the left, in the direction shown in the figure. Figure 4 As shown, when the connecting arm 8 drives the gate top rod 14 to move to the left via the drive guide rod 10, the gate top rod 14 reaches the bottom of the flip gate 16 and switches the flip gate 16 from a vertical state to a horizontal position, thereby sealing and separating the dust collector 1 and the ash collection hopper 3. The dust collector 1 continues to collect dust, while the ash collection hopper 3 simultaneously discharges ash.

[0043] Based on this, from Figures 4-6 As can be seen, elliptical truncated cylindrical blocks are provided in the middle of the switching combination rod 7 and at both ends of the threaded part. The elliptical truncated blocks are connected to the threaded end of the middle of the switching combination rod 7. In this way, when the connecting arm 8 moves to the left end of the threaded part, the bolt 9 in the connecting arm 8 will move back and forth along the elliptical trajectory of the elliptical truncated cylindrical block, ensuring that the drive component 4 rotates continuously and that the auger 13 conveys the dust outward.

[0044] Moreover, from Figure 3 , Figure 4 and Figure 6As can be seen, a valve core 6 is movably installed on one side of the ash collection hopper 3, and a valve push spring 601 is connected between the valve core 6 and the ash collection hopper 3. Under normal conditions, the valve core 6 blocks the ash discharge port of the ash collection hopper 3 under the elastic force of the valve push spring 601. A connecting arm 8 is movably installed at the end of the valve core 6. The connecting arm 8 can move along the side of the valve core 6. It should be noted that the connecting arm 8 on the valve core 6 and the connecting arm 8 on the switching combination rod 7 have the same structure and can be used interchangeably during installation. The top of the connecting arm 8 is fixedly connected to the drive guide rod 10 to ensure synchronous movement between the drive guide rod 10 and the connecting arm 8. In this way, in actual application, if the ash collection state is underway, the drive assembly 4 drives the switching combination rod 7 to rotate, causing the connecting arm 8 to move to the right along the switching combination rod 7, and causing the gate top rod 14 to move away from the flip gate plate 16. The flip gate plate 16 is in a vertical arrangement under its own weight. At the same time, when the drive guide rod 10 moves the connecting arm 8 on the left to the right, it will no longer pull the valve core 6. The valve closing spring 601 pushes the valve core 6 and blocks the ash discharge port of the ash collection hopper 3. Finally, the ash discharge port connecting the ash collection hopper 3 to the outside is blocked, and the flip gate 16 is in a vertical state. After the external airflow enters the dust collector 1, the dust collection component 102 adsorbs and collects the dust, and the dust collection component 103 shakes and cleans the dust collection component 102, so that the collected dust falls into the ash collection hopper 3 for collection. Figure 10 The state shown.

[0045] During ash discharge, the drive assembly 4 rotates, causing the connecting arm 8 to move to the left along the switching combination rod 7. The connecting arm 8, via the drive guide rod 10, causes the gate top rod 14 to push the tilting gate 16 to deflect, turning the tilting gate 16 to a horizontal position and achieving a sealed separation between the dust collector 1 and the ash collection hopper 3. After the tilting gate 16 is completely sealed, the connecting arm 8, continuing its leftward movement, moves towards the elliptical truncated cylindrical block on the left side of the switching combination rod 7. The connecting arm 8 on the left side of the drive guide rod 10 then begins to drive the valve core 6 to move to the left, disengaging the valve core 6 from the ash discharge port. Subsequently, as the drive assembly 4 continues to rotate, the auger 13 transports the dust inside the ash collection hopper 3 outwards. Figure 9 The state shown.

[0046] Example 2 is a supplement to Example 1; please refer to [link / reference]. Figures 4-6 It can be seen that a scraper blade 15 is bolted to the bottom of the drive guide rod 10, and the scraper blade 15 is slidably connected to the inclined inner side of the ash collection hopper 3. From Figure 4It is evident that there are multiple scraper blades 15, and these multiple scraper blades 15 are arranged at equal intervals. During the ash discharge process, when the drive assembly 4 drives the auger 13 and the switching combination rod 7 to rotate continuously, the connecting arm 8 on the right side reciprocates along the elliptical truncated cylindrical block on the left side of the switching combination rod 7. Specifically, when the bolt 9 drives the connecting arm 8 to the leftmost side of the elliptical truncated cylindrical block, the drive guide rod 10 drives the scraper blade 15 to move to the left, and the left connecting arm 8 further pulls the valve core 6, and the valve core 6 further compresses and stores force on the valve closing spring 601. After the bolt 9 passes the left end of the elliptical truncated cylindrical block, under the elastic force of the valve closing spring 601, the valve core 6 pulls the left connecting arm 8 to move to the right, and the drive guide rod 10 drives the scraper blade 15 to move to the right, until the bolt 9 moves to the junction of the left elliptical truncated cylindrical block and the threaded part. As the switching combination rod 7 rotates continuously, this cycle is repeated, realizing that the drive guide rod 10 drives the scraper blade 15 to reciprocate along the ash collection hopper 3. It should be noted that when bolt 9 reciprocates along the left elliptical truncated cylindrical block, the gate-closing rod 14 is always located below the flip gate 16, and the flip gate 16 is always in a horizontal arrangement.

[0047] When the scraper blade 15 moves back and forth along the inside of the dust collection hopper 3, it not only scrapes away the stubborn dust remaining on the inner wall of the dust collection hopper 3, but also breaks the arched structure of the dust inside the dust collection hopper 3 through the left and right reciprocating motion, making it easier for the dust to be discharged from the screw conveyor 13, and ultimately achieving the purpose of facilitating dust discharge.

[0048] Example 3 is a further improvement on Example 1. In order to enable autonomous ash discharge when the ash collection hopper 3 is full, it combines... Figure 1 , Figure 2 and Figure 8 It can be seen that a position detection disc 11 is fixedly installed at the end of the rotating shaft of the tilting gate 16, located on the outer side of the ash collection hopper 3. The shape of the position detection disc 11 is as follows: Figure 2 As shown in detail, the side of the cylinder is cut, with the cut surface parallel to the axis but not passing through the center. Correspondingly, a detection switch 12 is fixedly installed on the side of the dust collection box 1. The detection switch 12 is electrically connected to the power supply and control assembly 2. When the flip gate 16 is in the vertical position, the detection switch 12 is located at the notch of the position detection disk 11, and the position detection disk 11 will not turn on the detection switch 12. Conversely, when the flip gate 16 deflects, it drives the position detection disk 11 to rotate, and the position detection disk 11 squeezes the detection switch 12 and turns it on. It should be added that, in the implementation of this application, the number of position detection disks 11 and detection switches 12 can be adjusted as needed.

[0049] In practical application, when the drive assembly 4 drives the switching combination rod 7 to rotate and causes the bolt 9 to move the connecting arm 8 to the right, the bolt 9 eventually reciprocates along the elliptical truncated cylindrical block on the right. However, at this time, the valve core 6 blocks the ash discharge port of the auger 13, and while the connecting arm 8 drives the drive guide rod 10 to reciprocate left and right, the gate closing rod 14 periodically pushes the flipping gate 16, causing it to deflect. During this process, the reset problem of the bolt 9 after it passes the top of the elliptical truncated cylindrical block is addressed according to... Figure 6 It can be seen that a guide return spring 602 is connected between the valve core 6 and the connecting arm 8 sleeved on its outer side. When the bolt 9 moves along the right elliptical truncated cylindrical block of the switching combination rod 7, the drive rod 10 moves to the right and squeezes the guide return spring 602. After the bolt 9 passes the right end of the elliptical truncated cylindrical block, the connecting arm 8 moves to the left under the push of the guide return spring 602 until the bolt 9 moves to the junction of the threaded part in the middle of the switching combination rod 7 and the right elliptical truncated cylindrical block. At the same time, the gate closing rod 14 moves to the left and abuts against the flip gate plate 16 and deflects upward.

[0050] from Figure 8 As can be seen, multiple detection webs 160 are threaded onto the tilting gate 16. When the gate-closing rod 14 pushes the tilting gate 16 to deflect, the tilting gate 16 drives the detection webs 160 to deflect synchronously. If the amount of dust collected inside the dust collection hopper 3 is low at this time, when the bolt 9 moves to the right along the right-side elliptical truncated cylindrical block, the gate-closing rod 14 will also release its pushing action on the tilting gate 16, and the tilting gate 16 will return to its vertical state under its own weight.

[0051] If too much dust is collected in the dust collection hopper 3, when the gate shut-off rod 14 pushes the tilting gate 16 upward, the detection web 160 tilts upward simultaneously. After the detection web 160 leaves the dust accumulated inside the dust collection hopper 3, the collapse of the dust causes the detection web 160 to leave the area for filling. Subsequently, when the drive guide rod 10 moves to the right again, although the tilting gate 16 tends to move downward due to gravity, the detection web 160 is blocked by the dust layer, thus preventing the tilting gate 16 from returning to a vertical state. Therefore, the tilting gate 16 will always be in a tilted state. In conjunction with the above, when the tilting gate 16 tilts, the position detection disk 11 tilts simultaneously and presses down on the detection switch 12. When the detection switch 12 is pressed for a long time, the signal will also be transmitted to the power supply and control component 2. The power supply and control component 2 drives the drive component 4 to rotate in the opposite direction and causes the bolt 9 to move to the left along the switching combination rod 7, thereby completing the dust discharge mentioned above.

[0052] Based on this, it is clear from the above that when the drive assembly 4 rotates forward, the connecting arm 8 moves to the right along the switching combination rod 7; when the drive assembly 4 rotates in the reverse direction, the connecting arm 8 moves to the left along the switching combination rod 7. During this process, the auger 13 always rotates with the drive assembly 4. This is to ensure that the auger 13 does not rotate during the ash collection process in the ash collection hopper 3. Combined with... Figure 4 , Figure 5 and Figure 7 It can be seen that the valve core 6 has a locking groove 600 at its end, and correspondingly, the auger 13 shaft has a locking notch 130 at its end. When the locking notch 130 is inserted into the locking groove 600, it restricts the rotation of the auger 13, thereby increasing the rotational load on the auger 13. Thus, when the valve core 6 seals and closes the ash discharge port of the ash hopper 3, the engagement between the locking groove 600 and the locking notch 130 increases the rotational resistance of the auger 13. The drive assembly 4 drives the switching combination rod 7 to rotate continuously, but the torque limiting assembly 5 cuts off the power between the auger 13 and the drive assembly 4, ensuring that the auger 13 does not rotate during dust collection.
