Description

Technical Field

[0001] This invention relates to a dry filtration dust removal system for mining, specifically a dry filtration dust removal system suitable for high humidity and high dust environments, belonging to the field of mine safety and environmental protection technology. Background Technology

[0002] Dust pollution is a core hazard threatening miners' occupational health and mine safety during underground mining and transfer operations. It not only easily induces pneumoconiosis, but high concentrations of coal dust can also pose an explosion risk. Traditional spray dust suppression technology has significant limitations in practical applications: to ensure dust suppression efficiency, the spray system needs to generate a large number of tiny droplets (particle size mostly 1µm~50µm). After capturing dust, these droplets form dust-laden droplets, and some unsettled droplets diffuse within the roadway with the airflow. Especially in areas such as fully mechanized tunneling faces and belt conveyor transfer points, due to the disturbance of ventilation airflow, approximately 30% to 50% of the dust-laden droplets cannot settle naturally, leading to a significant increase in relative humidity within the roadway (often exceeding 80%), creating a high-humidity, dust-laden environment. This environment not only exacerbates equipment corrosion but also poses a severe challenge to subsequent dry dust removal systems.

[0003] With the development of intelligent and unmanned coal mining technologies, the requirements for the stability, efficiency, and low maintenance of underground dust removal systems are increasing. There is a need to develop high-efficiency dust removal technologies adapted to complex high-humidity conditions to achieve synergistic purification of dust and mist droplets. Existing dry dust removal systems suffer from several technical defects: ultrasonic devices operate independently, resulting in poor adaptability to operating conditions for agglomeration / agglomeration and low energy utilization; fixed filter plate and cartridge structures cannot cope with varying conditions such as high-humidity fine dust and low-humidity coarse dust, easily leading to condensation blockage or dust leakage; pressure potential energy and airflow kinetic energy are wasted during dust collection, and system energy consumption relies on external power supply; single module failures cause a sharp drop in system efficiency, lacking functional replacement mechanisms; independent and unintegrated sensor detection makes it easy for control parameter adjustments to deviate due to errors in a single sensor; and the biomimetic structure is a fixed physical structure with no inherent synergy with intelligent control, resulting in insufficient structural adaptability.

[0004] Therefore, in order to address the challenge of controlling residual dust droplets after spray dust suppression, the development of a dry filtration dust removal system for mining that can actively reduce spray droplets, balance dust collection efficiency and system stability, and achieve deep synergy across all modules has become an urgent need in the field of coal mine dust control. This system is of great significance for improving the quality of the underground working environment, protecting miners' occupational health, and ensuring safe production in mines.

Finally, the central controller is electrically connected to the dust concentration monitor and fan of the air outlet unit.

[0012] As a further improvement of the present invention, an electromagnetic coil electrically connected to the central controller is provided between the outer hydrophobic large-pore filter cartridge and the inner small-pore filter cartridge.

[0013] As a further improvement of the present invention, the support base of the ultrasonic nozzle is installed in the inner cavity of the primary dust removal unit by means of a drive roller including a roller drive component and a guide rail arranged along the circumferential direction of the inner cavity of the primary dust removal unit and cooperating with the drive roller. The roller drive component is electrically connected to the central controller.

[0014] As a further improvement of the present invention, a guide plate is provided inside the airflow diffusion unit. The bottom end of the guide plate is hinged to the inner cavity of the airflow diffusion unit, and a guide plate swing control mechanism electrically connected to the central controller is provided between the guide plate and the inner cavity of the airflow diffusion unit.

[0015] As a further improvement of the present invention, the filter cartridge cleaning unit includes a dual-cavity coaxial airflow nozzle II, a monitoring mechanism, and a telescopic rod II. The structure of the dual-cavity coaxial airflow nozzle II is the same as that of the dual-cavity coaxial airflow nozzle I. The dual-cavity coaxial airflow nozzle II is coaxially mounted on the telescopic end of the telescopic rod II and is located inside the double-layer adaptive filter cartridge. The base end of the telescopic rod II is positioned above the double-layer adaptive filter cartridge. The dual-cavity coaxial airflow nozzle II is connected to a high-pressure compressed air storage tank through a high-pressure gas input pipe II. The monitoring mechanism includes a differential pressure sensor and a particle size sensor II installed on the double-layer adaptive filter cartridge. The central controller is electrically connected to the monitoring mechanism and the telescopic rod II respectively.

[0016] As a further improvement of the present invention, the dual-cavity coaxial airflow jet nozzle II is also provided with an ultrasonic vibrator electrically connected to the central controller, and the ultrasonic vibrator has an ultrasonic transmitter built in.

[0017] As a further improvement of the present invention, the ash collection unit includes an ash collection chamber that communicates with the inner cavity of the secondary dust removal unit, and a push plate that is slidably connected to the inner cavity of the ash collection chamber. A hydraulic press including a hydraulic cylinder is provided on one side of the ash collection chamber corresponding to the push plate.

[0018] As a further improvement of the present invention, the ultrasonic pinholes are arranged on the biomimetic directional array support plate in a "dense in the middle and sparse at the edges" biomimetic directional array layout.

[0019] As a further improvement of the present invention, the mesh size of the shape memory alloy mesh skeleton is between the mesh size of the outer hydrophobic large-pore filter cartridge and the mesh size of the inner small-pore filter cartridge.

[0020] As a further improvement of the present invention, the central controller controls the ultrasonic generators of the ultrasonic atomization elimination device and the ultrasonic dust agglomeration device to emit fundamental frequency ultrasonic waves and harmonic ultrasonic waves, forming a dual-frequency interference standing wave field. Furthermore, the central controller controls the ultrasonic frequency of the ultrasonic generator based on the wind speed detected by the wind speed sensor. The quantitative mathematical expression for the relationship between ultrasonic frequency and wind speed is as follows:

[0021]

[0022] In the formula: Ultrasonic frequency; The synergy coefficient ranges from 0.08 to 0.12. The density of the dust-laden airflow; Wind speed; Target agglomeration particle size; It represents the dynamic viscosity of the airflow.

[0023] Compared with existing technologies, this dry filtration dust removal system for mining applications, suitable for high-humidity and high-dust environments, features an ultrasonic atomization elimination device, a hydrophobic filter plate assembly, and an ultrasonic dust agglomeration device within its primary dust removal unit. This forces dust particles to collide and agglomerate at the standing wave nodes of the standing wave field formed by the ultrasonic atomization elimination device and the ultrasonic dust agglomeration device. Tiny droplets in the high-humidity, dust-laden gas flowing through the primary dust removal unit can agglomerate into larger droplets under ultrasonic action and be intercepted by the large-pore hydrophobic filter plate of the hydrophobic filter plate assembly. The biomimetic micro-nano textures and hydrophobic coating on the large-pore hydrophobic filter plate significantly reduce the adhesion between droplets and dust. Larger droplets and dust particles can slide down the large-pore hydrophobic filter plate under their own gravity onto the bottom plate of the primary dust removal unit, achieving dehumidification of the high-humidity, dust-laden gas and removal of large dust particles. Furthermore, the secondary dust removal unit's double-layer adaptive filter cartridges, from the outside in, consist of an outer hydrophobic large-pore filter cartridge and a shape memory alloy mesh frame. The filter consists of a frame and an inner small-aperture filter cartridge. The sealed cavity of the shape memory alloy mesh skeleton contains magnetorheological fluid. Therefore, the current flowing through the magnetorheological fluid can be controlled by the magnetorheological control mechanism to control the deformation of the shape memory alloy mesh skeleton, thereby variably increasing or decreasing the airflow of the double-layer adaptive filter cartridge, thus adjusting the dust removal effect of the adaptive filter cartridge. The central controller can dynamically adjust the ultrasonic frequency of the ultrasonic generator in the primary dust removal unit, dynamically adjust the swing angle of the guide plate inside the airflow diffusion unit, and dynamically increase or decrease the airflow of the double-layer adaptive filter cartridge based on feedback from various sensors. This allows the primary and secondary dust removal units to work collaboratively under multi-field coupling conditions to enhance the dust removal effect of high-humidity dust-laden gas. On the one hand, this ensures that emissions meet standards; on the other hand, it solves problems such as easy condensation and clogging of filter media and leakage of micro-dust in high-humidity environments. It is particularly suitable for dust removal operations in high-humidity and high-dust environments. Attached Figure Description

The differential pressure sensor and particle size sensor II on the double-layer adaptive filter cartridge 41 provide real-time feedback to the central controller on the internal and external pressure difference and dust particle size of the adaptive filter cartridge 41. The weight sensor I provides real-time feedback to the central controller on the dust weight on the bottom plate of the primary dust removal unit 2. The weight sensor II provides real-time feedback to the central controller on the dust weight on the bottom plate of the dust collection chamber. The dust concentration monitor 71 provides real-time feedback to the central controller on the dust concentration of the gas entering the exhaust unit 7.

[0042] When the high-humidity, dust-laden gas flows through the primary dust removal unit 2, the central controller controls the ultrasonic generators 211 of the ultrasonic atomization elimination device 21 and the ultrasonic dust agglomeration device 24 to emit fundamental frequency ultrasonic waves and harmonic ultrasonic waves, forming a dual-frequency interference standing wave field. On the one hand, the central controller adaptively adjusts the ultrasonic frequency of the ultrasonic generator 211 according to the detected dust particle size (when the dust particle size is less than the set value, the central controller can control the ultrasonic frequency to increase to enhance the droplet agglomeration effect; when the dust particle size is greater than the set value, the central controller can control the ultrasonic frequency to decrease to reduce energy consumption). On the other hand, the central controller controls the ultrasonic frequency of the ultrasonic generator 211 according to the detected wind speed. The quantitative mathematical expression of ultrasonic frequency and wind speed is as follows:

[0043]

[0044] In the formula: Ultrasonic frequency; The synergy coefficient ranges from 0.08 to 0.12. The density of the dust-laden airflow; Wind speed; Target agglomeration particle size; The viscosity is the dynamic viscosity of the airflow.

[0045] The shape memory alloy flow guide 216 can adaptively adjust the ultrasonic field focusing degree according to the ambient temperature, and the shape memory alloy tilt angle adjustment component 26 can adaptively adjust the swing angle of the large-pore hydrophobic filter plate according to the ambient temperature.

[0046] The ultrasonic dust agglomeration device 24 uses harmonics and forms a standing wave field with the fundamental frequency of the ultrasonic atomization elimination device 21. This forces dust to collide and agglomerate at the standing wave nodes. Tiny droplets in the high-humidity dust-laden gas flowing through the primary dust removal unit 2 can agglomerate into larger droplets under the action of ultrasound. As the airflow moves, the larger droplets and dust can be intercepted by the large-pore hydrophobic filter plate of the hydrophobic filter plate assembly 22. The biomimetic micro-nano texture and polytetrafluoroethylene-silica composite hydrophobic coating on the large-pore hydrophobic filter plate can significantly reduce the adhesion between droplets and dust. The larger droplets and dust can slide down the large-pore hydrophobic filter plate to the bottom plate of the primary dust removal unit 2 under their own gravity. When the weight sensor I reports that the weight of the wet dust on the bottom plate of the primary dust removal unit 2 reaches the preset weight, the central controller controls the ash discharge plate opening and closing control mechanism to open the gravity ash discharge plate 25 and discharge the wet dust, thereby achieving dehumidification of the high-humidity dust-laden gas and removal of large dust particles.

[0047] After being processed by the primary dust removal unit 2, the dust-laden gas enters the airflow diffusion unit 3. The central controller, based on the humidity and pressure of the dust-laden gas detected by the humidity sensor and dust pressure sensor at the front end of the primary dust removal unit 2, and the differential pressure sensor on the double-layer adaptive filter cartridge 41 detecting the pressure difference between the inside and outside of the adaptive filter cartridge 41, bidirectionally adjusts the rotation angle of the guide plate inside the airflow diffusion unit 3. When the moisture content of the dust-laden gas entering the airflow diffusion unit 3 exceeds a set value, or when the dust pressure of the dust-laden gas entering the airflow diffusion unit 3 exceeds a set value, the central controller controls the guide plate angle to increase, thereby reducing the wind speed of the dust-laden gas entering the secondary dust removal unit 4. Simultaneously, the central controller controls the magnetorheological control mechanism 414 to adjust the shape memory alloy mesh skeleton 4. The magnetorheological fluid inside the shape memory alloy mesh skeleton 416 cools down due to the reduced current, thereby deforming the shape memory alloy mesh skeleton 416. This indirectly increases the airflow of the double-layer adaptive filter cartridge 41, thus enhancing the hydrophobic and liquid-guiding effect of the primary dust removal unit 2. When the pressure difference between the inside and outside of the adaptive filter cartridge 41 is less than the set value, the central controller controls the angle of the guide plate to decrease, thereby increasing the wind speed of the dust-laden gas entering the secondary dust removal unit 4. At the same time, the central controller controls the magnetorheological control mechanism 414 to make the magnetorheological fluid inside the shape memory alloy mesh skeleton 416 heat up due to the increased current, thereby deforming the shape memory alloy mesh skeleton 416. This indirectly reduces the airflow of the double-layer adaptive filter cartridge 41, thus enhancing the dust removal effect of the adaptive filter cartridge 41.

[0048] When the dust-laden gas entering the secondary dust removal unit 4 flows through the double-layer adaptive filter cartridge 41, the outer hydrophobic large-pore filter cartridge 412 intercepts residual droplets and large dust particles, while the inner small-pore filter material 413 intercepts fine dust particles. The dust-removed gas enters the outlet unit 7 through the upper cavity of the secondary dust removal unit 4. When the dust concentration monitor 71 detects that the dust concentration of the gas entering the outlet unit 7 is greater than the set value, the central controller controls to increase the ultrasonic frequency of the ultrasonic atomization elimination device 21 and the ultrasonic dust agglomeration device 24. At the same time, it controls the magnetorheological control mechanism 414 to make the magnetorheological fluid in the shape memory alloy mesh skeleton 416 heat up due to the increase of the current, thereby indirectly reducing the airflow of the double-layer adaptive filter cartridge 41 to enhance the dust removal effect of the adaptive filter cartridge 41, until the dust concentration detected by the dust concentration monitor 71 is less than the set value, ensuring that the emission meets the standards.

[0049] This dry filtration dust removal system for mining applications, suitable for high-humidity and high-dust environments, performs dust removal operations when the system operates for a set time or when the pressure difference between the inside and outside of the adaptive filter cartridge 41 exceeds a set value. For the primary dust removal unit 2, the central controller controls the telescopic rod I234 of the filter plate cleaning device 23 to extend and retract, while simultaneously controlling the high-pressure compressed air storage tank 236 to supply clean high-pressure cleaning air to the high-pressure gas input pipe I235. This clean air is then directed onto the surface of the large-aperture hydrophobic filter plate via the dual-cavity coaxial airflow nozzle I233. The double-layer sleeve structure of the dual-cavity coaxial airflow nozzle I233 allows the high-pressure cleaning air to form local turbulence within the outer cavity 2331, thereby indirectly increasing the injection pressure. The combined impact effect of the cleaning airflow removes dust from the surface of the large-aperture hydrophobic filter plate. The removed dust falls onto the bottom plate of the primary dust removal unit 2. The central controller then controls the opening and closing mechanism of the ash discharge plate to activate the gravity ash discharge plate 25. Open and discharge moist dust; for the secondary dust removal unit 4, the central controller first controls the base lifting mechanism of the sealed mounting base 411 to lower the sealed mounting base 411 and detach it from the outer hydrophobic large-pore filter cartridge 412, the inner small-pore filter cartridge 413 and the shape memory alloy mesh skeleton 416. Then, the central controller controls the telescopic rod II 54 to extend and retract while controlling the high-pressure compressed air storage tank 236 to supply clean high-pressure cleaning air to the high-pressure gas input pipe II 53. The dual-cavity coaxial airflow blowing nozzle II 51 blows the outer hydrophobic large-pore filter cartridge 412, the inner small-pore filter cartridge 413 and the shape memory alloy mesh skeleton 416 in a directional manner. The dust is stripped off by the impact and composite effect of the cleaning airflow. The stripped dust can fall into the dust collection chamber of the dust collection unit 6. Then, the central controller controls the electric door 63 to open and controls the hydraulic press 61 to move the push plate 613 to push out the stripped dust in the dust collection chamber.

[0050] To achieve better dust removal performance of the dual-layer adaptive filter cartridge 41, as a further improvement of the present invention, an electromagnetic coil electrically connected to the central controller is provided between the outer hydrophobic large-pore filter cartridge 412 and the inner small-pore filter cartridge 413. When the dual-cavity coaxial airflow blowing nozzle II 51 blows the outer hydrophobic large-pore filter cartridge 412, the inner small-pore filter cartridge 413, and the shape memory alloy mesh skeleton 416 in a directional manner, the central controller can control the electromagnetic coil to be energized to generate electromagnetic vibration, thereby achieving better dust removal performance of the dual-layer adaptive filter cartridge 41.

[0051] To achieve better dust removal performance of the dual-layer adaptive filter cartridge 41, as a further improvement of the present invention, an ultrasonic vibrator electrically connected to the central controller can be installed on the dual-cavity coaxial airflow jet nozzle II 51. The ultrasonic vibrator has a built-in ultrasonic transmitter. When the dual-cavity coaxial airflow jet nozzle II 51 performs directional jetting on the outer hydrophobic large-pore filter cartridge 412, the inner small-pore filter cartridge 413, and the shape memory alloy mesh skeleton 416, the central controller can control the ultrasonic vibrator to generate vibrating ultrasonic waves, thereby achieving better dust removal performance of the dual-layer adaptive filter cartridge 41.

[0052] To achieve better ultrasonic agglomeration, as a further improvement of the present invention, the support base 214 of the ultrasonic nozzle is installed inside the cavity of the primary dust removal unit 2 via a drive roller 215 including a roller drive component and a guide rail arranged along the circumferential direction of the cavity of the primary dust removal unit 2 and cooperating with the drive roller 215. The roller drive component is electrically connected to the central controller. The central controller can control the synchronous rotation of the drive roller 215 to realize the circular motion of multiple centrally symmetrically arranged ultrasonic nozzles within the cavity of the primary dust removal unit 2, thereby achieving a better ultrasonic agglomeration effect.

[0053] This dry filtration dust removal system for mining applications, suitable for high humidity and high dust environments, can dynamically adjust the ultrasonic frequency of the ultrasonic generator 211 in the primary dust removal unit 2, dynamically adjust the swing angle of the guide plate inside the airflow diffusion unit 3, and dynamically adjust the airflow of the double-layer adaptive filter cartridge 41 to increase or decrease. This allows the primary dust removal unit 2 and the secondary dust removal unit 4 to work together under multi-field coupling conditions to enhance the dust removal effect of high humidity dust-laden gas. On the one hand, it can ensure that emissions meet standards, and on the other hand, it can solve problems such as easy condensation and clogging of filter media and leakage of micro-dust in high humidity environments. It is particularly suitable for dust removal operations in high humidity and high dust environments.
