Abstract
Description
Technical Field
[0001] This invention relates to the field of flue gas separation technology for fly ash-based materials, specifically to a flue gas separation device for the production of fly ash-based materials. Background Technology
[0002] Fly ash-based materials are new building materials made primarily from fly ash produced by coal-fired power plants. Their production process requires efficient separation and collection of fly ash from flue gas to obtain pure fly ash raw materials. Electrostatic precipitators, with their advantages of large air volume handling capacity, high separation efficiency, and low operating resistance, have become key flue gas separation equipment in fly ash-based material production lines.
[0003] In an electrostatic precipitator, dust-laden flue gas passes through a high-voltage electric field zone. Fly ash particles become charged and are captured on the surface of the anode plate. After being vibrated and cleaned, the ash falls into the ash collection hopper and is finally discharged by the ash unloading system and transported to the ash silo. Existing electrostatic precipitators typically use gravity unloading for their ash collection hoppers, relying on the hopper's inclination angle and lining material to prevent ash accumulation. Some equipment is equipped with loosening devices such as air cannons and silo vibrators to assist in ash removal.
[0004] However, with the increasing demands for finer raw materials in fly ash-based materials, the particle size of fly ash collected in flue gas is becoming increasingly smaller, resulting in a significantly larger specific surface area. This type of ultrafine fly ash has poor flowability and is prone to agglomeration, easily forming bridging or rat-hole phenomena within the ash collection hopper. Existing loosening devices can only provide intermittent external intervention, making it difficult to continuously break up the already formed agglomerated layer, leading to frequent blockages at the ash collection hopper outlet. A continuous rise in ash level may flood the electric field area, causing short circuits between the anode and cathode, forcing equipment shutdown, and severely impacting the continuity of fly ash-based material production and the stability of raw material supply.
[0005] Therefore, it is necessary to provide a flue gas separation device for the production of fly ash-based materials to solve the above problems. Summary of the Invention

[0018] 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.
[0019] Please see Figure 1-13 The present invention provides a technical solution: a flue gas separation device for the production of fly ash-based materials, comprising a base 1, a shell 2, several sets of electrode mechanisms 3 and a dust collection mechanism 4. The dust collection mechanism 4 is disposed on the top of the base 1, the shell 2 is disposed on the top of the dust collection mechanism 4, and the several sets of electrode mechanisms 3 are arranged in a matrix inside the shell 2. The shell 2 is used to form a sealed flue gas channel and support internal components. The electrode mechanisms 3 are used to generate an electric field and realize the charging and collection of dust. The dust collection mechanism 4 is used to collect and discharge dust.
[0020] Specifically, such as Figure 1 and Figure 3 As shown, an air inlet 21 and an air outlet 22 are respectively provided on both sides of the housing 2. The air inlet 21 is used to guide the flue gas to enter evenly, and the air outlet 22 is used to guide the flue gas to exit. A temperature sensor for detecting the flue gas temperature and a humidity sensor for detecting the flue gas humidity are fixedly connected to the inner wall of the air inlet 21. A particulate matter sensor for detecting the particulate content in the flue gas after dust removal is fixedly connected to the inner wall of the air outlet 22.
[0021] Specifically, such as Figure 2As shown, the electrode mechanism 3 includes several cathode wires 31 and several anode plates 32. The cathode support and anode support are fixedly connected inside the housing 2. The cathode wires 31 are disposed on the cathode support, and the anode plates 32 are disposed on the anode support. The cathode wires 31 and anode plates 32 are arranged alternately. The cathode wires 31 and anode plates 32 are connected to a high-voltage power supply system for providing power support.
[0022] It should be noted that the cathode support and anode support are respectively equipped with a rapping mechanism for rapping the cathode wire 31 and anode plate 32 to make the dust attached to them fall off. The rapping mechanism is an existing basic structure, which is not shown in the figure and will not be described in detail here.
[0023] Specifically, such as Figure 4 and Figure 5 As shown, the dust collection mechanism 4 includes a dust collection frame 41, a dust collection hopper 42, a guide port 44, four sets of dust guiding components 5 and a dredging component 6. The dust collection frame 41 is fixed to the top of the base 1, the housing 2 is fixed to the top of the dust collection frame 41, the dust collection hopper 42 is fixed inside the dust collection frame 41, and the guide port 44 is fixed to the top of the dust collection hopper 42. The guide port 44 is located inside the dust collection frame 41 and below the housing 2. The top cross-sectional size of the guide port 44 matches the bottom opening size of the housing 2. The guide port 44 is an opening with a large top cross-sectional size and a small bottom cross-sectional size. The guide port 44 is used to guide the dust cleaned off the cathode wire 31 and the anode plate 32 into the dust collection hopper 42. The bottom of the dust collection hopper 42 is tapered, and the ash outlet 43 is fixedly connected to the center of the bottom of the dust collection hopper 42. The ash guiding component 5 is set inside the bottom of the dust collection hopper 42. Four sets of ash guiding components 5 are equidistantly arranged inside the dust collection hopper 42 along the circumference of the ash outlet 43. The ash guiding component 5 is used to assist in ash cleaning and avoid dust accumulation. The unblocking component 6 is used to guide the dust at the ash outlet 43 and prevent the ash outlet 43 from being blocked.
[0024] Furthermore, such as Figures 5-10 As shown, the dust guiding assembly 5 includes a dust guiding plate 51, a dust guiding side plate 52, a spring 53, two sets of lifting parts, several detection parts, and two sets of sliding parts. The dust guiding plate 51 is trapezoidal in shape, with its narrower end close to the dust outlet 43. There is a gap between the dust guiding plate 51 and the inner wall of the bottom of the dust collection hopper 42. The end of the dust guiding plate 51 close to the dust outlet 43 is hinged to the dust collection hopper 42, and the end of the dust guiding plate 51 away from the dust outlet 43 is hinged to the dust guiding side plate 52. The spring 53 is disposed between the dust guiding plate 51 and the dust guiding side plate 52, and the two ends of the spring 53 are fixedly connected to the dust guiding plate 51 and the dust guiding side plate 52, respectively.
[0025] Furthermore, such as Figure 7 , Figure 8 and Figure 12As shown, both sets of lifting parts are set at the bottom of the guide plate 51. The lifting part includes a slide block 54, a slider 55, an extension rod 57 and a telescopic rod 58. The slide block 54 is fixed at the bottom of the guide plate 51. The slider 55 is set inside the slide block 54 and is slidably connected to the slide block 54. The slider 55 has a movable hole 56. The bottom of the slider 55 is hinged to the extension rod 57. The hinge point between the slider 55 and the extension rod 57 is located inside the movable hole 56. Several limiting cylinders 45 are fixedly connected to the bottom of the dust collection hopper 42. The limiting cylinders 45 correspond to the positions of the extension rods 57. The extension rods 57 are located inside the limiting cylinders 45 and are slidably connected to the limiting cylinders 45.
[0026] It should be noted that when the telescopic rod 58 is fully retracted, the dust guide plate 51 remains parallel to the dust collection hopper 42; the bottom of the telescopic rod 58 is fixed to the external support surface.
[0027] Furthermore, such as Figure 5 and Figure 9 As shown, several detection units are fixed at equal intervals on the dust collection hopper 42. Each detection unit includes a pressure block 59, a fixed cylinder 510, a second spring 511, and a pressure sensor 515. The bottom of the fixed cylinder 510 is fixedly connected to the dust collection hopper 42. The pressure block 59, the second spring 511, and the pressure sensor 515 are all located inside the fixed cylinder 510. The pressure block 59 is slidably connected to the fixed cylinder 510, and the pressure sensor 515 is fixedly connected to the fixed cylinder 510. The two ends of the second spring 511 are fixedly connected to the pressure block 59 and the pressure sensor 515, respectively.
[0028] Furthermore, such as Figure 10 and Figure 11 As shown, two sets of sliding sections are installed on the dust collection hopper 42. The sliding section includes a second sliding block 512 and a second sliding block 513. Two sets of limiting ports are opened on the side wall of the dust collection hopper 42. The second sliding block 512 is installed in the limiting ports and is fixedly connected to the dust collection hopper 42. The second sliding block 513 is installed in the second sliding block 512. The top of the dust guiding side plate 52 is hinged to the second sliding block 513 on the side near the second sliding block 512. A scraper is also provided on the side of the dust guiding side plate 52 near the second sliding block 512. The scraper contacts the inner wall of the dust collection hopper 42 and is used to scrape off the dust on the side wall of the dust collection hopper 42. A top block 514 is fixedly connected to the top of the dust guide side plate 52 near the guide port 44. When the slider 2 513 is located at the top of the slider 2 512, the top block 514 contacts and collides with the top of the guide port 44 near the dust collection hopper 42.
[0029] In practice, such as Figure 13As shown, the extension rod 58 is extended, causing the extension rod 57 to rise, so that the hinge of the extension rod 57 and the slider 55 is located at the top of the movable hole 56. Then, the slider 55 lifts the dust guide plate 51, causing the dust guide plate 51 to rotate counterclockwise around the hinge of the dust guide plate 51 and the dust collection hopper 42, increasing the angle between the dust guide plate 51 and the dust collection hopper 42, so that the dust on the dust guide plate 51 can slide down to the center of the dust collection hopper 42 and be discharged from the ash outlet 43. Since the position of the limiting cylinder 45 is fixed, the extension rod 57 can only move in the vertical direction, but the slider 55 is slidably set in the slide seat 54. When the dust guide plate 51 is lifted, the slider 55 moves away from the hinge of the dust guide plate 51 and the dust collection hopper 42 in the slide seat 54, so that the dust guide plate 51, the bottom of the dust collection hopper 42, and the extension rod 57 continue to form a triangular support state, ensuring the support effect of the dust guide plate 51. Meanwhile, since the dust guide side plate 52 is hinged to the dust guide plate 51, and the dust guide side plate 52 is hinged to the slider 513, and the slider 513 is slidably disposed in the slide block 512, and the slide block 512 is vertically disposed, when the dust guide plate 51 is lifted, the dust guide side plate 52 will also be lifted simultaneously, causing the slider 513 to slide upward in the slide block 512. The scraper on the side of the dust guide side plate 52 near the dust collection hopper 42 scrapes away the dust on the side wall of the dust collection hopper 42, preventing dust from adhering to the side wall of the dust collection hopper 42, thus achieving dust collection hopper 42 Self-cleaning; during this process, the angle between the dust guide side plate 52 and the side wall of the dust collection hopper 42 increases, the angle between the dust guide side plate 52 and the dust guide plate 51 increases, the spring 53 is stretched, which disrupts the original fixed setting angle of the dust guide plate 51 and the dust guide side plate 52, thereby disrupting the dust agglomeration state on the dust guide plate 51 and the dust guide side plate 52 and the original dust accumulation state that slid down along the dust guide side plate 52 and accumulated at the hinge of the dust guide side plate 52 and the dust guide plate 51, so that the dust can slide down along the dust guide plate 51 with the increased angle; When the telescopic rod 58 is fully extended, the top block 514 on the top of the dust guide side plate 52 contacts the guide port 44 and is in a slight collision state. Under the action of the vibration and interaction force of the collision, the dust adhering to the guide port 44, the dust guide side plate 52, and the dust guide plate 51 falls off, realizing the self-cleaning of the guide port 44, the dust guide side plate 52, and the dust guide plate 51, and keeping the surface clean.
[0030] Conversely, when the telescopic rod 58 retracts, the hinge between the extension rod 57 and the slider 55 is located at the bottom of the movable hole 56. Then, the downward-moving extension rod 57 drives the slider 55 downward, causing the guide plate 51 to descend, reducing the angle between the guide plate 51 and the dust hopper 42. Then, through the hinge between the guide plate 51 and the guide side plate 52 and the contraction of the spring 53, the angle between the guide plate 51 and the guide side plate 52 and the angle between the guide side plate 52 and the side wall of the dust hopper 42 are reduced, causing the slider 513 to slide down in the slide block 512 until the guide plate 51 and the dust hopper 42 are parallel, and the angle between the guide side plate 52 and the side wall of the dust hopper 42 is reduced to the minimum.
[0031] When the telescopic rod 58 is fully retracted, if there is no dust accumulation on the dust guide plate 51, the dust guide plate 51 is parallel to the dust collection hopper 42, the dust guide plate 51 is close to or in contact with the pressure block 59, and the pressure value detected by the pressure sensor 515 is small or barely noticeable, that is, it remains within the set safety range, which is set by the staff. If dust accumulates on the dust guide plate 51, under the weight of the dust guide plate 51 and the gravity of the dust, the dust guide plate 51 rotates around the hinge point with the dust collection hopper 42 towards the bottom of the dust collection hopper 42. This reduces the distance between the end of the dust guide plate 51 away from the dust collection hopper 42 and the dust collection hopper 42, causing the dust guide plate 51 to contact the pressure block 59. The pressure block 59 slides to one side of the fixed cylinder 510 within the fixed cylinder 510, and is then transmitted to the pressure sensor 515 through the second spring 511. This causes the pressure value detected by the pressure sensor 515 to increase until the pressure value exceeds the set safety range. During this process, the hinge point between the slider 55 and the extension rod 57 moves from the bottom of the movable hole 56 to the top of the movable hole 56. The slider 55 slides adaptively within the slide block 54 to maintain the stability of the triangular relationship formed by the dust guide plate 51, the dust collection hopper 42, and the extension rod 57. If the dust is in block form and falls directly onto the dust guide plate 51 from inside the housing 2 or the guide port 44, or if the telescopic rod 58 retracts rapidly and the dust guide plate 51 rotates around the hinge point with the dust collection hopper 42 towards the side closer to the fixed cylinder 510 due to the inertia of the dust guide plate 51, the dust guide plate 51 will suddenly come into contact with the pressure block 59 or even collide with it. This will cause the spring 511 to compress and the pressure value detected by the pressure sensor 515 to increase. At the same time, the interaction force will cause the dust collection hopper 42 and the dust guide plate 51 to vibrate, thereby causing the dust on the dust collection hopper 42, the dust guide plate 51, and the dust guide side plate 52 hinged to the dust guide plate 51 to fall off, preventing the continuous accumulation of dust and achieving a self-cleaning effect.
[0032] Specifically, such as Figures 5-7As shown, the unblocking component 6 includes a motor 61, a drive cylinder 62, several guide fan blades 63 and propeller blades 64. A support 65 is fixedly connected to the bottom of the dust collection hopper 42. The motor 61 is fixed on the support 65. The drive cylinder 62 is set in the ash outlet 43 and rotatably connected to the ash outlet 43. A transmission port 431 is opened on the side of the ash outlet 43 near the support 65. The output end of the motor 61 passes through the support 65 and is gear-driven connected to the drive cylinder 62. The transmission connection between the motor 61 and the drive cylinder 62 is located in the transmission port 431. The top sidewall of the drive cylinder 62 is provided with several ash guide ports at equal intervals, and several guide fan blades 63 are arranged at equal intervals along the circumference of the drive cylinder 62. The guide fan blades 63 are fixedly connected to the drive cylinder 62, and the guide fan blades 63 and the ash guide ports are arranged alternately. The propeller blades 64 are fixed to the top of the drive cylinder 62.
[0033] In actual operation, the motor 61 starts and drives the drive cylinder 62 to rotate through gear transmission, which in turn drives the guide fan blade 63 and the propeller blade 64 to rotate, so that the dust accumulated at the bottom of the dust collection hopper 42 can enter the drive cylinder 62 along the propeller blade 64 and the dust guide port, and be discharged from the drive cylinder 62.
[0034] The flue gas separation equipment also includes a monitoring system for monitoring the flue gas dust removal effect. The monitoring system is electrically connected to a temperature sensor, a humidity sensor, a particulate matter sensor, and a pressure sensor 515. The monitoring system is also electrically connected to the dust collection mechanism 4 and the high-voltage power supply system to control the operation of the integrated mechanism 4 and to regulate the voltage and current of the high-voltage power supply system.
[0035] It should be noted that the flue gas separation equipment is also equipped with pre-treatment equipment, such as cooling and drying devices; the flue gas separation equipment is also equipped with observation windows for observing the internal condition.
[0036] Operation method of flue gas separation equipment for fly ash-based material production: Step 1: Preparation and Monitoring: Before starting the equipment, the control and monitoring system is initialized, and the data from the temperature and humidity sensors at the air inlet 21 and the particulate matter sensor at the air outlet 22 are read in real time.
[0037] When the flue gas temperature or humidity exceeds the optimal operating range of electrode mechanism 3, for example, excessively high temperature may reduce the electric field strength, and excessive humidity may cause electrode creep or dust adhesion, the monitoring system automatically adjusts the pre-treatment equipment, such as cooling and drying devices, or adjusts the output parameters of the high-voltage power supply system to ensure the charging and collection efficiency of electrode mechanism 3. The monitoring system records the initial particulate matter concentration value as a reference for subsequent judgment of dust removal efficiency and dust removal timing.
[0038] Step 2, Flue Gas Charging and Collection: Flue gas enters the interior of the housing 2 evenly through the air inlet 21. The high-voltage power supply system supplies power to the cathode wire 31 and the anode plate 32, forming a strong electric field. The dust in the flue gas is charged in the electric field and is collected by the anode plate 32 under the action of the electric field force. The monitoring system dynamically adjusts the voltage and current of the high-voltage power supply system based on the real-time feedback from the particulate matter sensor at the air outlet 22.
[0039] Step 3, Intelligent dust removal and collection: The rapping mechanism rappels the cathode wire 31 and anode plate 32 according to the set cycle, causing the captured dust to fall into the guide port 44 below and be collected in the dust collection hopper 42.
[0040] Specifically, the dust guiding assembly 5 operates in a coordinated manner: the telescopic rod 58 extends, and through the triangular support structure of the extension rod 57, slider 55, and slide block 54, it smoothly lifts the dust guiding plate 51. During this process, the dust guiding side plate 52 rises synchronously, its scraper cleans the side wall of the dust collection hopper 42, and the spring 53 is stretched, breaking the dust agglomeration. Afterward, the monitoring system controls the telescopic rod 58 to retract, the dust guiding plate 51 returns to a parallel state with the dust collection hopper 42, the pressure sensor 515 reading drops, the monitoring system determines that the dust cleaning is complete, and resumes standby monitoring.
[0041] Continuous operation of the unblocking component 6: The motor 61 continuously or intermittently drives the drive cylinder 62 to rotate, which in turn drives the guide fan blade 63 and the propeller blade 64 to rotate; when dust accumulates at the ash outlet 43, the propeller blade 64 provides downward conveying force, and the guide fan blade 63 guides the surrounding dust to the ash outlet, ensuring that the dust is continuously and smoothly discharged from the ash outlet 43.
[0042] Dust accumulation detection: The detection unit monitors the amount of dust accumulation on the dust guide plate 51 in real time. When the pressure sensor 515 value exceeds the set safety range, it indicates that the dust guide plate 51 is seriously dusty. The monitoring system controls the telescopic rod 58 to actively lift the dust guide plate 51 for cleaning, increasing the angle between the dust guide plate 51 and the dust collection hopper 42, and accelerating the dust to slide down to the dust outlet 43. If the pressure value fluctuates violently for a moment, the monitoring system determines it to be an abnormal impact. At this time, the vibration generated by the impact can be used to assist the dust to fall off.
[0043] When the humidity sensor at the air inlet detects that the humidity of the flue gas is too high, the monitoring system determines that the dust adhesion is enhanced. At this time, the monitoring system controls the telescopic rod 58 to increase the frequency and amplitude of its movement, ensuring that the scraper on the dust guide side plate 52 scrapes the side wall of the dust collection hopper 42 more frequently to prevent wet dust from caking. At the same time, the collision frequency between the top block 514 and the guide port 44 will also increase, enhancing the self-cleaning effect.
[0044] It should be noted that the monitoring system can automatically adjust the speed of the motor 61 based on the feedback from the pressure sensor 515 or a preset time interval, thereby achieving a balance between energy saving and ash removal efficiency.
[0045] Step 4: Emission and Recirculation Monitoring: The treated flue gas is discharged through outlet 22, and the particulate matter sensor continuously monitors the emission concentration. If the emission value exceeds the preset standard, the monitoring system will trigger an alarm, prompting the operator to check the equipment's sealing or the status of electrode mechanism 3.
[0046] The above methods can prevent fly ash-based materials from caking and clogging in the ash hopper.
