Description

Technical Field

[0001] This invention belongs to the field of dust control technology, specifically relating to a dust suppression device for mines based on functional microorganisms. Background Technology

[0002] Currently, mining operations, especially in the extraction, transportation, and blasting stages, generate large amounts of dust, severely impacting air quality and worker health, and increasing the risk of occupational diseases and accidents. Existing dust control technologies mostly employ mechanical, chemical, or physical methods, such as spraying and vacuuming. While these methods are effective to some extent, they often suffer from drawbacks such as high energy consumption, high cost, and significant environmental impact. In recent years, functional microbial technology has been increasingly applied to environmental remediation. Utilizing the adsorption and degradation capabilities of functional microorganisms or plants, it has become an emerging environmental protection technology. By optimizing the growth environment of functional microorganisms or plants, their dust capture and degradation effects can be improved. With the rapid development of the Internet of Things, sensor technology, and artificial intelligence, intelligent monitoring and automated control systems have been widely applied in various fields. Combining these technologies with dust control systems can achieve real-time monitoring, data analysis, and intelligent adjustment, thereby improving dust control effectiveness and efficiency.

[0003] Therefore, an intelligent storage and recycling mine functional microbial dust suppression device adopts intelligent control, which enables the dust suppression vehicle to automatically identify the route in the mine, reducing the operation process of on-site personnel, and can monitor the running status of the mine vehicle in real time to ensure the normal operation of the equipment. The efficient and intelligent storage and recycling system realizes the efficient recycling and utilization of resources, which is in line with the concept of sustainable development. The functional microbial dust removal system sprays more environmentally friendly and safe functional microbial dust suppressants. Through three-stage impact atomization and cutting, the contact area between the functional microbial dust suppressant and the dust is increased, thereby improving the dust suppression rate.

[0009] The ventilation duct is horizontally installed on the left side above the main body of the vehicle, with two ash discharge ports spaced apart at the bottom. Its rear end is connected to the feed port on the shell.

[0010] The pretreatment system includes a detachable filter device, a transmission mechanism, a fan, and a dust collection hopper. The detachable filter device includes a filter clamp and a filter screen. The filter clamp is annular, with its outer diameter matching the inner diameter of the ventilation duct. Two filter clamps interlock, forming an annular installation space between them. The filter screen is circular, with its outer diameter matching the inner diameter of the ventilation duct. The filter screen is positioned between the two filter clamps, with its outer edge fixedly installed in the annular installation space, and a toothed ring fixedly installed at its center. The transmission mechanism is positioned between the two detachable filter devices, with its two output ends connected to the toothed rings in each device, driving the two devices to rotate synchronously. The fan is installed at the rear end of the ventilation duct. The dust collection hopper has a dust collection port at its upper end. Two dust collection hoppers are installed side-by-side on the upper part of the main body of the vehicle, corresponding directly below the two dust discharge ports.

[0011] The intelligent control system is connected to the camera, fan, transmission mechanism, lifting pump one, lifting pump two, centrifuge, briquetting system, conveyor, motor and telescopic rod respectively.

[0012] Furthermore, in order to provide lighting functionality so that normal operation can be carried out in relatively dark environments, headlights are installed at the front and rear of the main body of the vehicle, and the headlights are connected to the intelligent control system.

[0013] As a preferred embodiment, in order to make the structure of the detachable filter device more reasonable and to facilitate disassembly and maintenance, the detachable filter device further includes a combination buckle, a spring device, a latch, and a collision ball;

[0014] Two combination buckles are respectively set between the upper and lower ends of the two filter clips; the combination buckles are composed of male and female buckles that are fixedly connected to the two filter clips, and are used to achieve a fixed connection between the two filter clips through the buckling connection.

[0015] The spring device is fixedly installed on one of the filter clips, and the buckle is connected to the spring device and connected to the spring in the spring device to pull the filter screen tight on the filter clip;

[0016] The collision ball is a hemispherical structure, and two collision balls are fixedly connected to the outer ends of two filter clips. Two semi-circular protrusions are fixedly connected on the ventilation pipe at the positions corresponding to the two collision balls. During the rotation of the detachable filter device, the two collision balls and the two semi-circular protrusions contact and cooperate, causing the filter to vibrate.

[0017] Furthermore, in order to improve the spraying effect, the rotary pressure sprayer is divided into a low-pressure zone, a medium-pressure zone, and a high-pressure zone from top to bottom.

[0018] Furthermore, to enhance the overall level of intelligence, the intelligent control system includes a terminal display, an embedded computer, an emergency braking system, an intelligent storage control system, a slide rail control system, a fault detection system, an energy management system, a motor, an emergency braking system, a steering wheel system, a drive system, a thickness sensor, a humidity sensor, a temperature sensor, a mass sensor, a lidar device, a positioning system, a wireless communication system, and a radio interference suppression device.

[0019] As a preferred embodiment, the three-stroke atomizing nozzle includes a nozzle body, with a liquid inlet pipe and an air inlet pipe connected to the upper left and right sides of the nozzle body, respectively. Its internal space is arranged with three two-phase impact zones and a cutting blade from bottom to bottom, and an atomizing nozzle is connected to its bottom.

[0020] Furthermore, to ensure the filtration effect, the detachable filter device is provided with one or more filters, and the pore size of the filters in the two detachable filter devices decreases sequentially.

[0021] As a preferred embodiment, the flip plate is made of a hydrophobic polymer coating material that allows the functional microbial dust suppressant to pass through but does not allow the mineralized coal powder to pass through.

[0022] Compared with the prior art, the present invention has at least the following advantages:

[0023] (1) This invention combines Internet of Things and sensor technology to monitor dust status and environmental parameters in real time, automatically adjust working status, ensure the best dust removal effect, and adjust according to different mine environments and dust characteristics through cloud data analysis, which has good adaptability and flexibility.

[0024] (2) This invention realizes the efficient recycling of resources. The intelligent storage and recycling system recycles the used functional microbial mineralized dust suppressant and restores its activity by using functional microbial regeneration technology. This can significantly improve the utilization efficiency of resources, reduce operating costs, reduce environmental pollution, and create sustainable development opportunities for enterprises and society.

[0025] (3) The pretreatment system of the present invention can remove dust of multiple particle sizes at the same time. The filter screen can be replaced and stacked at will as needed. With the rotation of the rotating shaft, the collision ball on the filter screen clamp collides with the collision ball on the pipe wall once for each rotation, which can realize automatic dust removal without manual dust removal, reduce human resource costs and extend the service life of the equipment.

[0026] (4) The functional microbial dust removal system of the present invention uses functional microbial mineralization dust suppressants. Functional microbial dust removal technology is environmentally friendly, avoiding the use of chemical agents and reducing the risk of secondary pollution. It can form solid minerals through functional microbial reactions, binding dust particles together, thereby reducing suspended particles in the air and improving mine air quality. Secondly, functional microbial mineralization inhibitors are generally more environmentally friendly, avoiding the harmful substances or secondary pollution that may result from traditional chemical methods. Furthermore, the functional microbial mineralization method is relatively low-cost and can work continuously, reducing dust hazards in mine operations and improving worker health and safety.

[0027] (5) The present invention designs a novel atomizing nozzle, wherein the liquid inlet channel has a gradually narrowing pipe section, the air inlet channel has a gradually narrowing pipe diameter, the two liquid inlet pipes are distributed around the air inlet pipe, the liquid inlet channel and the air inlet channel are respectively impacted and atomized in three two-phase impact zones, the truncated blade is located at the upper part of the atomizing nozzle of the three-impact atomizing nozzle, the atomized liquid can become finer after passing through the blade, and finally sprayed out through the atomizing nozzle; the atomized functional microbial dust suppressant can be sprayed quickly and evenly, and can form a protective film in the air to provide a continuous dust suppression effect.

[0028] This system, through the coordination of the vehicle body, intelligent control system, pretreatment system, functional microbial dust removal system, and intelligent storage and recycling system, uses environmentally friendly and safe functional microbial mineralized dust suppressants to effectively improve dust suppression efficiency through automated and intelligent control. It also intelligently recycles and utilizes gel, coal powder, and functional microbial mineralized dust suppressants, reducing resource waste while improving construction site safety and work efficiency.

[0043] The present invention will now be clearly and completely described with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of the present invention.

[0044] In the description of this invention, it should be noted that the terms "upper," "middle," "lower," "front," "back," "center," "inner," and "outer," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are merely simplified descriptions for the convenience of describing this invention; therefore, they should not be construed as limitations on this invention. Furthermore, terms such as "first," "second," and "third" are used for descriptive purposes only and should not be interpreted as indicating their relative importance.

[0045] like Figures 1 to 13 As shown, the present invention provides a dust suppression device for mines based on functional microorganisms, including a main body 1, an intelligent storage and recycling system 6, a functional microorganism dust removal system 5, a ventilation pipe 2, a pretreatment system 3, and an intelligent control system 4;

[0046] The bottom of the main body 1 is equipped with multiple pairs of wheels 8, and anti-collision strips 7 and multiple cameras 10 are installed around it; among them, the cameras 10 are used to collect image data of the surroundings in real time, so as to realize the real-time positioning and path planning of the main body 1.

[0047] The intelligent storage and recycling system 6 is installed on the right side of the upper part of the main body 1. It includes a washing room 65, a functional microorganism replenishment room 66, a functional microorganism mineralization dust suppressant collection box 67, a centrifuge 61, a briquetting system 62, a gel storage box 64, and a coal block collection box 63. The intelligent storage and recycling system 6 is divided into upper and lower layers. The upper layer is used to collect gel and coal powder, and the lower layer is used to recycle functional microorganism mineralization dust suppressant. The washing room 65, the functional microorganism replenishment room 66, and the functional microorganism mineralization dust suppressant collection box 67 are arranged adjacent to each other from left to right. Located on the lower level, the washing room 65 has a spray network at its top and a dust suppressant collection pipeline at its bottom. The washing room 65 is used to clean the dust suppressant, removing adsorbed dust and impurities. The dust suppressant then enters the functional microbial replenishment room 66. The inlet of the functional microbial replenishment room 66 is connected to the outlet of the dust suppressant collection pipeline, and it is equipped with a nutrient supply pipeline for restoring the activity of the dust suppressant. By replenishing the functional microorganisms with the nutrients required for mineralizing the dust suppressant, the functional microorganisms gradually restore the dust suppressant's activity. Subsequently, the active dust suppressant is periodically and quantitatively introduced into the functional microbial mineralization dust suppressant collection box 67, and mixed with the unused functional microbial mineralization dust suppressant in the collection box 67 to ensure that the regenerated dust suppressant has a longer dust suppression time. The inlet of the functional microbial mineralization dust suppressant collection box 67 is connected to the outlet of the functional microbial replenishment room 66, and a second lifting pump is installed inside it. The centrifuge cylinder 61 and the briquetting system 62 are arranged adjacent to each other at the front of the upper layer, and the two are connected by a conveyor. The centrifuge cylinder 61 has a feed inlet at its left end, and its bottom drain pipe extends downwards into the washing room 65. The centrifuge cylinder 61 is used to separate mineralized coal powder from the functional microbial mineralizing dust suppressant that adheres to it, and discharges the centrifuged functional microbial mineralizing dust suppressant into the washing room 65. The gel storage box 64 is used to collect the scraped gel and is located at the rear of the upper layer. It has a feed inlet at its left end and is equipped with a lifting pump. The coal block collection box 63 is located at the right end of the upper layer, and its feed inlet is connected to the discharge port of the briquetting system 62.

[0048] The functional microbial dust removal system 5 includes a support frame 54, a shell 51, an outer rotating cylinder 59, an inner rotating cylinder 56, a rotary pressure sprayer 57, a motor 52, a telescopic rod 512, a spiral scraper 513, a pipe 53, a tilting plate 55, and a swing discharge pipe 56. The support frame 54 is installed in the middle section of the upper part of the main body 1. The shell 51 is vertically installed on the support frame 54, and a feed inlet is opened in the middle of its front side. The outer diameter of the outer rotating cylinder 59 is adapted to the inner diameter of the upper part of the shell 51. The upper end of the outer rotating cylinder 59 is open and rotatably connected to the upper end of the inner cavity of the shell 51. An internal gear ring is coaxially fixedly connected inside the outer rotating cylinder 59. The inner rotating cylinder 56 is coaxially arranged inside the outer rotating cylinder 59, and its upper end is rotatably connected to the upper end of the inner cavity of the shell 51. An outer gear ring is fixedly fitted on the outside of the inner rotating cylinder 56 at the position corresponding to the internal gear ring. An annular cavity space is formed between the rotating cylinder 56 and the outer rotating cylinder 59; the rotary pressure sprayer 57 is fixedly connected to the lower end of the inner rotating cylinder 56, and several three-stroke atomizing nozzles 58 are installed circumferentially thereon; two motors 52 are fixedly connected to the top plate of the housing 51 from left to right, and the output shafts of the two motors 52 can be rotatably extended into the annular cavity space; two rotating connecting assemblies 511 are installed from left to right in the annular cavity space, and the input ends of the two rotating connecting assemblies 511 are respectively connected to the output shafts of the two motors 52. The output ends of the two rotating connecting assemblies 511 can rotate relative to their input ends. When the output ends of the two rotating connecting assemblies 511 rotate to the outer side, they simultaneously mesh with the inner gear ring to synchronously drive the outer rotating cylinder 59 to rotate. When the output ends of the two rotating assemblies rotate to the inner side, they simultaneously mesh with the outer gear ring to synchronously drive the inner rotating cylinder 56 to rotate.

[0049] As a preferred embodiment, when the rotary pressure sprayer 57 stops working, the output ends of the two rotating connecting components 51 rotate to the outside, thereby facilitating the starting of the rotation of the outer rotating cylinder 59. At this moment, the two telescopic rods 512 can be controlled to gradually extend, pushing the spiral scraper 513 to gradually move downwards a certain distance. In this way, the extended spiral scraper 513 can be used to scrape off the gel adhering to the inner wall of the housing 51. After the scraping operation is completed, the two telescopic rods 512 can be controlled to retract synchronously, driving the spiral scraper 513 to move upwards, returning to the initial state. New gel can be replenished by the booster pump 2. Through the rotation of the rotary pressure sprayer 57, the contact area between the spray and the dust can be wider, thereby effectively improving the dust removal efficiency.

[0050] Two telescopic rods 512 are arranged opposite each other, and their fixed ends are respectively fixedly connected to the left and right ends of the lower edge of the outer rotating cylinder 59; the spiral scraper 513 is spirally wrapped around the outside of the rotary pressure sprayer 57, and its upper left and right sides are respectively fixedly connected to the telescopic ends of the two telescopic rods 512; when the rotary pressure sprayer 57 is working, the two telescopic rods 512 are in the maximum retracted state, retracting the spiral scraper 513 to the top to avoid affecting the spraying operation of the rotary pressure sprayer 57; when the rotary pressure sprayer 57 is not in operation, the two telescopic rods 512 are in the maximum retracted state, retracting the spiral scraper 513 to the top to avoid affecting the spraying operation of the rotary pressure sprayer 57. During operation, the two telescopic rods 511 extend to gradually push the spiral scraper 513 downwards. The maximum downward extension distance of the spiral scraper 513 is 5 cm. After reaching this extension distance, it is fixed to maintain this extension length. In this state, the motor 52 drives the outer rotating cylinder 59 to rotate, thereby driving the spiral scraper 513 to rotate and contact the inner wall of the housing 51 to scrape off the gel adhering to the inner wall of the housing 51. When the spiral scraper 513 retracts upwards, or before it begins to extend downwards, gel can be sprayed onto the inner wall of the housing 51 through the gel nozzle 514 to absorb the coal dust. This facilitates the scraping action of the spiral scraper 513 to remove the gel along with the coal dust.

[0051] The spiral scraper 513 has a hollow structure with several coagulation nozzles evenly connected along its length. An inlet is provided on the scraper, which is connected to the outlet of the first lifting pump via a connecting pipe. The inlet of the pipe 53 is connected to the outlet of the first lifting pump, and its outlet is connected to the inlet of the rotary pressure sprayer 57 after passing through the top of the housing 51. The tilting plate 55 is installed at a certain angle at the bottom of the inner cavity of the housing 51, which improves the discharge rate of coal powder and gel. The tilting plate 55 can swing relative to the housing 51 at a certain angle. The tilting plate 55 is used to collect falling mineralized coal blocks and scrape off falling gel. A discharge port is provided above the lower end of the flip plate 55, and a swing discharge pipe 56 is movably connected to the outside of the discharge port. During the swinging process, the swing discharge pipe 56 is connected to the inlet of the centrifuge cylinder 61 or the inlet of the gel storage box 64. When the rotary pressure sprayer 57 is working, the discharge port of the swing discharge pipe 56 is connected to the inlet of the centrifuge cylinder 61 so as to discharge the collected mineralized coal powder into the centrifuge cylinder 61 for centrifugation. When the spiral scraper 513 is working, the discharge port of the swing discharge pipe 56 is connected to the inlet of the gel storage box 64 so as to discharge the scraped and fallen gel into the gel storage box 64.

[0052] The ventilation pipe 2 is horizontally arranged on the left section above the main body 1, and two ash discharge ports are opened at intervals at the bottom of the pipe, and its rear end is connected to the feed port on the housing 51.

[0053] The pretreatment system 3 includes a detachable filter device 31, a transmission mechanism 32, a fan 33, and a dust collection hopper 34. The detachable filter device 31 includes a filter clip 311 and a filter 35. The filter clip 311 is annular, and its outer diameter matches the inner diameter of the ventilation duct 2. The two filter clips 311 interlock, forming an annular installation space between them. The filter 35 is circular, and its outer diameter matches the inner diameter of the ventilation duct 2. The filter 35 is positioned between the two filter clips 311, and its outer edge is fixedly installed in the annular installation space. A toothed ring is fixedly installed in the center, allowing the filter screen 35 to be easily disassembled, providing high flexibility. The transmission mechanism 32 is located between the two detachable filter screen devices 31, with its two output ends connected to the toothed rings in the two detachable filter screen devices 31 respectively, for driving the two detachable filter screen devices 31 to rotate synchronously. The fan 33 is installed at the rear end of the ventilation pipe 2. The upper end of the ash collection hopper 34 is provided with an ash receiving port. The two ash collection hoppers 34 are installed side by side on the upper part of the main body 1, and are respectively located directly below the two ash discharge ports.

[0054] The intelligent control system 4 is used to realize the unmanned and intelligent operation of the dust suppression vehicle, and is connected to the camera 10, fan 33, transmission mechanism 32, lifting pump one, lifting pump two, centrifuge 61, briquetting system 62, conveyor, motor 52 and telescopic rod 512 respectively.

[0055] In order to provide lighting functionality so that normal operation can be carried out in darker environments, vehicle lights 9 are installed at the front and rear of the main body 1, and the vehicle lights 9 are connected to the intelligent control system 4.

[0056] In order to make the structure of the detachable filter device more reasonable, and to facilitate disassembly and maintenance, the detachable filter device 31 also includes a combination buckle 312, a spring device 314, a latch 315 and a collision ball 313.

[0057] Two combination buckles 312 are respectively set between the upper and lower ends of the two filter clips 311; the combination buckle 312 is composed of a male and female buckle that are fixedly connected to the two filter clips 311, and is used to achieve a fixed connection between the two filter clips 311 through the buckle connection. In this way, the filter 35 can be prevented from shifting with the pair of filter clips 311 during rotation, thereby affecting the filtration efficiency.

[0058] The spring device 314 is fixedly installed on one of the filter clips 311. The buckle 315 is connected to the spring device 314 and connected to the spring in the spring device 314, which is used to pull the filter 35 tight on the filter clip 311. In this way, the filter 35 can be effectively prevented from shaking in the filter clip 311.

[0059] The collision balls 313 are hemispherical in shape, and two collision balls 313 are fixedly connected to the outer ends of the two filter clips 311. Two semi-circular protrusions are fixedly connected to the ventilation pipe 2 at positions corresponding to the two collision balls 313. During the rotation of the detachable filter device 31, the two collision balls 313 contact and engage with the two semi-circular protrusions, causing the filter 35 to vibrate. Thus, during the rotation of the detachable filter device 31, the collision of the collision balls 313 with the semi-circular protrusions causes the filter 35 to vibrate with a certain amplitude and frequency, thereby completing the dust removal process. This facilitates the rapid removal of dust adhering to the filter 35 and its pouring into the dust collection hopper 34 from the discharge port, eliminating the need for manual dust removal.

[0060] To improve the spraying effect, the rotary pressure sprayer 57 is divided into a low-pressure zone, a medium-pressure zone, and a high-pressure zone from top to bottom.

[0061] To enhance the overall intelligence level, the intelligent control system 4 includes a terminal display 41, an embedded computer 42, an emergency braking system 43, an intelligent storage control system 44, a slide rail control system 45, a fault detection system 46, an energy management system 47, a motor 48, an emergency braking system 49, a steering wheel system 410, a drive system 411, a thickness sensor 412, a humidity sensor 413, a temperature sensor 414, a mass sensor 415, a lidar device 416, a positioning system 417, a wireless communication system 418, and a radio interference suppression device 419. The radio interference suppression device 419 can reduce electromagnetic interference and improve communication quality. Humidity sensor 413 and temperature sensor 414 are used to monitor the humidity and temperature of the gas in the mine to ensure the safety of the working environment. The data measured by the sensors are also used to calculate the pressing index θ. Thickness sensor 412 and mass sensor 415 are used to monitor the thickness and mass of the mineralized products on the conveyor belt of the briquetting system 62. The measured thickness and mass are used to calculate the pressing index θ. The pressing index θ is used to determine whether the coal powder formed by functional microbial mineralization can be pressed into briquettes. When the limiting pressing index is reached, the briquetting system 62 starts to work, and the pressed coal briquettes are transported into the coal briquette collection box 63 through the conveyor belt. The pressing index θ is calculated according to formula (1).

[0062]

[0064] The energy management system 47 is used for battery management and energy recovery, monitoring battery status, optimizing the charging and discharging process, improving energy utilization, and recovering energy during braking or downhill driving to improve overall energy efficiency. The fault detection system 46 is used to monitor the operation of various parts, analyze data through sensors, provide early warning of potential faults, reduce downtime, and display and alarm on the terminal display 41 via the embedded computer 42 if abnormal data is detected. The emergency braking system 43 automatically closes after an alarm, allowing the dust suppression vehicle to stop smoothly. The intelligent storage control system 44 and the slide rail control system 45 are used for the recycling and utilization of gel, mineralized coal powder, and functional microbial dust suppressants.

[0065] As a preferred embodiment, the embedded computer 42 adds navigation algorithms, path planning algorithms, control algorithms, and machine learning models to upload data obtained from other components to the cloud for analysis. Data transmission between the dust suppression vehicle and the ground-based central control center is achieved through the wireless communication system 418 for timely adjustments. The positioning system 417 includes GPS / IMU for positioning and measurement, and LiDAR for high-precision map building and obstacle detection. The lidar device 416 and camera 10 assist the positioning system 417 in positioning. The lidar device 416 detects the distance between obstacles and the mine car; the data is transmitted to the embedded computer 42, and then, based on the analyzed data, the emergency braking system 49 and the steering wheel system 410 control the steering and braking of the mine car. The fault detection system 46 detects the working status of the thickness sensor 412, humidity sensor 413, temperature sensor 414, mass sensor 415, lidar device 416, and positioning system 417. If any device malfunctions, the system will detect the fault. In case of an anomaly, an alarm is immediately triggered on the computer, alerting ground control center personnel for inspection. When inspection is required, personnel can quickly locate the dust suppression vehicle using the positioning system 417, minimizing downtime. The emergency braking system 43 activates for emergency braking after the fault detection system 46 alarms. The wireless communication system 418 connects to the terminal display 41 and the radio interference suppression device 419, sending stable signals to the ground control center. The energy management system 47 connects to the motor 48 and the drive system 411, controlling the use of the motor 48's battery and energy recovery while simultaneously supplying power to the energy management system 47. The thickness sensor 412, humidity sensor 413, temperature sensor 414, and mass sensor 415 are all connected to the briquetting system 62, and the data obtained determines whether the briquetting system 62 is operational. The intelligent storage control system 44 connects to the intelligent storage and recycling system 6, controlling the start and stop of each component within this system. The slide rail control system 45 connects to the tilting plate 55 and the slide rail 56, classifying coal lumps and gels.

[0066] As a preferred embodiment, the three-stroke atomizing nozzle 58 includes a nozzle body, with a liquid inlet pipe 581 and an air inlet pipe 582 connected to the upper left and right sides of the nozzle body, respectively. Its internal space, from bottom to top, is arranged with three two-phase impact zones 583 and a truncating blade 584, and an atomizing nozzle 585 is connected to its bottom. Both the air inlet pipe 582 and the liquid inlet pipe 581 are tapered pipes. The liquid inlet channel 581 and the air inlet channel 582 are atomized sequentially by the impact of the three two-phase impact zones 583. The atomized liquid becomes finer after passing through the truncating blade 584, which facilitates more efficient atomization and spraying after passing through the atomizing nozzle 585.

[0067] To ensure filtration effectiveness, the detachable filter device 31 is equipped with one or more filter screens 35. The pore size of the filter screens 35 in the two detachable filter devices 31 decreases sequentially, thus filtering out particles of different size ranges. Preferably, the detachable filter device 31 in the pretreatment system 3 can be freely disassembled, replaced, and installed with different numbers of filter screens 35 of varying particle sizes, allowing for flexible adjustment of the detachable filter device 3.

[0068] As a preferred embodiment, the flip plate 55 is made of a hydrophobic polymer coating material that allows the functional microbial dust suppressant to pass through but does not allow the mineralized coal powder to pass through.

[0069] In operation, dust-laden gas passes through a pretreatment system to remove relatively large dust particles. A fan is installed between the pretreatment system and the functional microbial dust collection system to create negative pressure and draw in air. The functional microbial dust collection system is then installed after the fan. The dust particles subsequently enter the system for both physical and biological dust removal. A spiral scraper and rotating nozzle are installed at the top of the system, working alternately in a 1:9 ratio. The spiral scraper can extend and retract vertically and rotate to scrape away gel from the inner wall of the dust collector housing. At the bottom of the system is an angled tilting plate coated with a hydrophobic polymer material to prevent mineralization and inhibition by the functional microorganisms. The dust agent adheres to the surface, allowing it to pass through, and the generated coal lumps remain on top. When the coal lumps reach a certain weight, they can be discharged into the intelligent storage and recycling system through the swing discharge pipe along with the collected material on the tipping plate. The intelligent storage and recycling system is installed to the right of the functional microbial dust removal system to collect the used gel and functional microbial mineralization dust suppressant, and to recycle them using efficient functional microbial degradation technology. At the same time, the coal lumps formed by functional microbial mineralization will also enter the system for recycling. The intelligent control system is installed behind the pretreatment system and the functional microbial dust removal system, and is connected to the vehicle body, the pretreatment system, the functional microbial dust removal system, and the intelligent storage and recycling system to realize the intelligentization of the device.

[0070] This system, through the coordination of the vehicle body, intelligent control system, pretreatment system, functional microbial dust removal system, and intelligent storage and recycling system, uses environmentally friendly and safe functional microbial mineralized dust suppressants to effectively improve dust suppression efficiency through automated and intelligent control. It also intelligently recycles and utilizes gel, coal powder, and functional microbial mineralized dust suppressants, reducing resource waste while improving construction site safety and work efficiency.
