Description

Technical Field

[0001] This application relates to the field of dust control technology, and in particular to a method, apparatus, electronic device and storage medium for suppressing dust during coal transportation. Background Technology

[0002] During the operation of coal conveying systems in coal mines, coal washing plants, and thermal power plants, a large amount of coal-containing wastewater containing coal slime particles is generated, as well as a significant amount of dust. Current environmental policies impose stringent requirements on wastewater treatment and dust suppression in such scenarios. Traditional treatment methods require physical and chemical treatment of coal-containing wastewater, consuming large amounts of chemical agents and electricity, and the wastewater is not efficiently utilized as a resource. Traditional dust suppression often uses gas-liquid two-phase flow mechanical atomization systems. These systems have poor pollution resistance and cannot directly treat coal-containing wastewater, requiring the use of clean demineralized water, resulting in serious water waste. Furthermore, the atomized particles are relatively large, limiting the dust suppression effect. They also lack the ability to precisely control the particle size, making it impossible to adjust the atomization effect according to the actual particulate matter in the coal-containing wastewater, resulting in poor adaptability. In addition, the atomization requires high water pressure, leading to high overall operating energy consumption and costs. Summary of the Invention

[0003] This application provides a method, apparatus, electronic device, and storage medium for suppressing dust generated during coal transportation. It addresses the problems in related technologies where coal-containing wastewater requires additional physicochemical treatment, consumes large amounts of reagents and electricity without being utilized as a resource; traditional dust suppression systems have poor anti-fouling capabilities and cannot directly treat coal-containing wastewater, requiring the use of clean demineralized water, resulting in water waste; and they lack precise control over atomized particle size, have limited adaptability to dust suppression, and limited effectiveness.

[0005] Magnetization treatment is applied to coal-containing wastewater to reduce its surface tension and dynamic viscosity. An alternating electric field is applied to the magnetized coal-containing wastewater using an electric standing wave generator to generate standing wave resonance, causing the coal-containing wastewater to atomize and break up. Detecting the particle size of particulate matter in coal-containing wastewater; Based on the detected particle size, the frequency of the alternating electric field is controlled by a PLC controller to adjust the particle size of the atomized particles after atomization.

Detailed Implementation

[0014] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of this application, including various details to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0015] The following description, with reference to the accompanying drawings, describes a method, apparatus, electronic device, and storage medium for suppressing coal conveying dust according to embodiments of this application.

[0016] Figure 1 This is a schematic flowchart of a method for suppressing dust during coal transportation, provided in an embodiment of this application.

[0017] like Figure 1 As shown, the method includes the following steps: Step 101: Magnetize the coal-containing wastewater to reduce its surface tension and dynamic viscosity.

[0018] In some embodiments, before performing atomization treatment related to dust suppression on coal-containing wastewater, a magnetization treatment is first performed on the wastewater. The wastewater to be treated is passed into a magnetizer, and the magnetic field generated by the magnetizer creates a continuous physical effect on the wastewater. Under the influence of the magnetic field, the internal water molecule structure of the coal-containing wastewater changes. The originally associated water molecule clusters are broken down into smaller water molecule units, and the polarity arrangement of water molecules becomes more ordered. This change at the molecular level directly reduces the surface tension of the coal-containing wastewater. At the same time, the magnetic field also weakens the adhesion force between coal slurry particles and water molecules in the coal-containing wastewater, improves the overall rheology of the coal-containing wastewater, reduces intermolecular friction within the water body, and thus effectively reduces the dynamic viscosity of the coal-containing wastewater. The entire magnetization treatment process is carried out purely physically, without adding any chemical agents to the coal-containing wastewater. The physical properties of the water are optimized and adjusted solely through the interaction between the magnetic field and the water body, so that the surface tension and dynamic viscosity of the coal-containing wastewater reach the suitable state required for subsequent atomization and crushing treatment.

[0019] The treatment of coal-containing wastewater is accomplished through physical methods, eliminating the need for chemical reagents, saving reagent costs and avoiding secondary pollution. At the same time, it effectively reduces the surface tension and dynamic viscosity of coal-containing wastewater, creating favorable material conditions for subsequent atomization and crushing processes, and improving the overall efficiency of subsequent treatment.

[0020] Step 102: An alternating electric field is applied to the magnetized coal-containing wastewater using an electric standing wave generator to generate standing wave resonance, causing the coal-containing wastewater to atomize and break up.

[0021] In some embodiments, the magnetized coal-containing wastewater is continuously introduced into the processing chamber of an electric standing wave generator. An alternating electric field is applied to the wastewater within the chamber, causing the internal vibration components to vibrate regularly. This vibrational energy is transferred to the wastewater, generating stable standing waves. During propagation, these waves form periodic peaks and troughs, resulting in alternating pressure changes between high and low pressures. This keeps the water in a dynamic state of continuous tension, compression, and oscillation, leading to a strong standing wave resonance effect. Under the influence of standing wave resonance, the coal-containing wastewater, whose surface tension and dynamic viscosity have been reduced by magnetization, is rapidly torn apart, gradually forming fine droplets for atomization. Simultaneously, the coal slurry particles in the wastewater are further impacted and broken up by the mechanical force generated by the resonance. This achieves simultaneous atomization and particle breakage of the coal-containing wastewater. Furthermore, the magnetized wastewater exhibits superior physical properties, better responding to the energy effects of standing wave resonance, making the atomization and breakage process more efficient. By utilizing the standing wave resonance generated by the alternating electric field, the coal-containing wastewater is atomized and broken up. Combined with the characteristics of the water after magnetization treatment, the efficiency and effect of atomization and breaking up are improved, resulting in finer droplets and more thorough particle breakage, laying a good foundation for subsequent dust suppression.

[0022] Step 103: Detect the particle size of particulate matter in coal-containing wastewater.

[0023] In some embodiments, after the coal-containing wastewater has undergone magnetization treatment and before it enters the electric standing wave generator for atomization and crushing treatment, particle size detection is performed on the coal slime particles in the wastewater. Particle size detectors are installed in the conveying pipeline of the coal-containing wastewater, allowing the wastewater to flow continuously and stably through the detection area. These detectors, based on specialized detection principles, continuously and dynamically scan the coal-containing wastewater within the area, accurately capturing the characteristic signals of different coal slime particles in the wastewater. The captured characteristic signals are then professionally converted and analyzed to accurately identify the actual particle size of the coal slime particles in the wastewater. Simultaneously, the detectors comprehensively capture the distribution of particles in different size ranges within the wastewater, achieving continuous and accurate detection of the particle size of the coal-containing wastewater. This ensures that the detection data accurately and promptly reflects the actual material state of the current coal-containing wastewater. All particle size-related data obtained are collected in real time and transmitted synchronously, providing direct and reliable data support for subsequent electric field frequency control operations.

[0024] Step 104: Based on the detected particle size, the frequency of the alternating electric field is controlled by the PLC controller to adjust the particle size of the atomized particles after atomization.

[0025] In some embodiments, the particle size data of coal-containing wastewater detected by the particle size detector is transmitted in real time to a PLC controller. This PLC controller, as the core control unit, rapidly analyzes and processes the received particle size data. Combining this with the actual requirements for atomized particle size in coal conveying dust suppression, a precise control correlation is established between particle size and alternating electric field frequency. The PLC controller establishes a stable electrical linkage control relationship with the electric field generation module of the electric standing wave generator. Based on the analyzed particle size results, it sends a corresponding frequency control signal to the electric field generation module, thereby changing the frequency of the alternating electric field applied by the electric standing wave generator. When the detected particle size of the coal-containing wastewater is too large, the PLC controller adjusts and increases the frequency of the alternating electric field to enhance the energy intensity of the standing wave resonance, allowing the coal-containing wastewater to be more fully atomized and broken up under stronger resonance, resulting in smaller atomized particles. When the detected particle size is too small, the PLC controller appropriately reduces the frequency of the alternating electric field, ensuring that the atomized particles meet dust suppression requirements while achieving rational energy utilization. The entire control process is dynamically adjusted according to changes in particle size detection data, forming a real-time closed-loop control to ensure that the particle size of the atomized particles after atomization treatment can always accurately match the actual working conditions required for dust suppression.

[0026] Step 105: Spray the atomized coal-containing wastewater onto the dust-generating area of ​​the coal conveyor belt to suppress dust.

[0027] In some embodiments, the coal-containing wastewater after atomization exists in the form of fine dry mist. This atomized wastewater is delivered to the dust-generating area of ​​the coal conveyor belt via a dedicated atomizing spray assembly. The spraying end of the atomizing spray assembly is precisely positioned to correspond to the core area of ​​dust generation on the coal conveyor belt, ensuring that the sprayed dry mist can uniformly and comprehensively cover the entire dust-generating area along the operating direction of the coal conveyor belt and the trajectory of dust diffusion. The particle size of the atomized dry mist is precisely controlled to be highly adapted to the actual needs of dust suppression. It can fully contact, collide with, and adsorb suspended coal dust particles in the air, allowing the originally dispersed suspended coal dust particles to combine with the atomized particles to form a denser solid-liquid agglomerate. Because the agglomerate is much heavier than a single coal dust particle, it will quickly settle under gravity and fall back onto the coal conveyor belt, preventing the spread of coal dust particles to the surrounding environment at the source. The entire spraying process can maintain a stable dry fog output based on the continuous operation of the coal conveyor belt, continuously acting on the dust-generating area to ensure the continuity of dust suppression operations. Moreover, the atomized coal-containing wastewater directly acts on the dust-generating area without the need for additional water sources, allowing the coal-containing wastewater to directly exert its dust suppression effect after atomization treatment.

[0028] Compared with related technologies, in this embodiment, the surface tension and dynamic viscosity of the coal-containing wastewater are reduced by magnetizing it; an alternating electric field is applied to the magnetized coal-containing wastewater using an electric standing wave generator to generate standing wave resonance, causing the coal-containing wastewater to atomize and break up; the particle size of the particles in the coal-containing wastewater is detected; based on the detected particle size, the frequency of the alternating electric field is controlled by a PLC controller to adjust the particle size of the atomized particles; and the atomized coal-containing wastewater is sprayed onto the dust-generating area of ​​the coal conveyor belt to suppress dust. This technology can solve the problems in related technologies, such as the need for additional physical and chemical treatment of coal-containing wastewater, the consumption of large amounts of reagents and electricity, and the lack of resource utilization; the poor anti-pollution ability of traditional dust suppression systems, which cannot directly treat coal-containing wastewater and require the use of clean demineralized water, resulting in water waste; and the lack of precise control over the particle size of atomized particles, as well as the limited adaptability and effectiveness of dust suppression. It can achieve the resource utilization of coal-containing wastewater, save reagents, electricity and water resources, precisely control the particle size of atomized particles to improve the adaptability and effectiveness of dust suppression, and efficiently achieve the technical effect of suppressing dust during coal transportation.

[0029] Figure 2 A schematic flowchart of another method for suppressing coal conveying dust provided in this application embodiment includes the following steps: Step 201: Before the coal-containing wastewater enters the electric standing wave generator, the coal-containing wastewater is magnetized by a magnetizer installed on the branch pipe of the coal-containing wastewater.

[0030] In some embodiments, during the magnetization treatment of coal-containing wastewater, the magnetizer is directly installed on the branch pipe of the coal-containing wastewater. The magnetizer is installed at the connection point between the branch pipe and the electric standing wave generator, allowing the coal-containing wastewater to undergo a pretreatment process of magnetization before entering the electric standing wave generator for subsequent atomization and crushing. After being diverted from the main pipe, the coal-containing wastewater enters each branch pipe. During its continuous transport along the pipeline within the branch pipe, it first flows through the magnetizer on the branch pipe. The magnetizer is seamlessly connected to the branch pipe, ensuring that all the coal-containing wastewater in the branch pipe can pass smoothly through the magnetic field area of ​​the magnetizer without water stagnation or sideflow. This ensures that every portion of the coal-containing wastewater to be treated in the branch pipe can fully contact the magnetic field generated by the magnetizer. The flow velocity of coal-containing wastewater in the branch pipe is matched with the magnetic field strength of the magnetizer. This ensures that the magnetization is not insufficient due to excessive water flow, nor is the overall transportation and treatment efficiency of the coal-containing wastewater affected by excessively slow flow. The magnetization process is naturally integrated into the branch pipe transportation process of the coal-containing wastewater. There is no need to set up a separate treatment chamber and transportation path for the magnetization operation. After the coal-containing wastewater is magnetized in the branch pipe, it can directly enter the electric standing wave generator from the branch pipe, achieving a seamless connection from magnetization treatment to subsequent atomization and crushing treatment.

[0031] By placing the magnetizer in the branch pipe of the coal-containing wastewater and in front of the electric standing wave generator, the magnetization treatment and wastewater transportation are integrated, simplifying the pipeline layout of the overall process and eliminating the need for additional treatment space. At the same time, it ensures that the coal-containing wastewater is fully magnetized, improving the magnetization treatment efficiency. After magnetization, the wastewater directly enters the generator, reducing energy loss during water transportation and ensuring the continuous and efficient operation of subsequent processes.

[0032] Step 202: Input 220VAC power into the power generator, rectify it from AC to DC, and then output an AC frequency of 35kHz to the electric standing wave generator via a DC to AC generator.

[0033] In some embodiments, when powering an electro-hydraulic standing wave generator to produce an alternating electric field, a power generator serves as the core power conversion unit, directly connected to the conventional 220V AC mains power used in industrial production. This mains power serves as the input power for the power generator, first entering its internal AC-to-DC rectifier module for rectification. The rectifier module, through its internal circuit conversion structure, converts the alternating 220V AC power into stable DC power. This process effectively filters voltage fluctuations and current noise present in the mains power, eliminating the adverse effects of unstable power on the subsequent electric field, and establishing a stable and reliable power foundation for the subsequent frequency conversion stage. The rectified and stabilized DC power then enters the DC-to-AC converter module of the power generator. This module, relying on precise circuit inversion principles, converts the DC power back into AC power, precisely outputting AC power at a frequency of 35kHz. This specific frequency AC power is continuously and stably supplied to the electro-wave generator, becoming the energy source for generating its alternating electric field. This ensures that the electro-wave generator can generate a frequency-matched and intensity-stable alternating electric field based on this 35kHz AC frequency, thereby exciting the standing wave resonance effect within the cavity that meets the requirements for atomization and fragmentation. The entire power conversion process is completed integratedly within the power generator, with smooth power transmission between the various conversion modules. The voltage and frequency conversion accuracy are both within a controllable range, continuously providing suitable power support for the stable operation of the electro-wave generator.

[0034] Step 203: The particle size of the particulate matter in the coal-containing wastewater is detected by a particle size detector that is fixedly installed in the coal-containing wastewater header.

[0035] In some embodiments, when detecting the particle size of particulate matter in coal-containing wastewater, the particle size detector is fixedly installed on the main pipeline of the coal-containing wastewater. A dedicated fixing structure ensures a stable connection between the detector and the main pipeline, effectively resisting the vibrations generated during the transportation of coal-containing wastewater and preventing detector displacement or loosening. This ensures the stability of the detection device and the continuous and orderly operation of the detection work. The main pipeline serves as the central pipeline for the centralized transportation of coal-containing wastewater. All coal-containing wastewater to be treated first collects in the main pipeline for unified transportation, and then flows from the main pipeline to various branch pipes. The particle size detector is fixed at this location, and its detection area completely covers the water flow channel within the main pipeline. This allows all coal-containing wastewater transported in the main pipeline to flow smoothly through the detector's detection area, achieving full-scale detection of the particle size of the coal-containing wastewater. The detection data accurately and comprehensively reflects the particle size distribution and size of the entire coal-containing wastewater to be treated, rather than just sampling wastewater from a portion of the branch pipes. During the continuous transport of coal-containing wastewater within the main pipe, a fixedly installed particle size detector continuously and dynamically monitors the flowing wastewater, accurately capturing the particle size characteristic signals of different particles in the wastewater. After internal signal conversion and data analysis, the detector generates particle size detection data in real time. The fixed installation eliminates the need for frequent position adjustments, ensuring stable detection accuracy over a long period. The detected particle size data is collected in real time and synchronously transmitted to the PLC controller, providing unified and reliable basic data support for the subsequent alternating electric field frequency control of each branch pipe.

[0036] By fixing the particle size detector to the main pipe of coal-containing wastewater, full and real-time detection of particulate matter size in coal-containing wastewater can be achieved. The detection data can reflect the overall particulate matter status of the wastewater and provide a unified basis for subsequent control of each branch pipe. The fixed installation method ensures the stability and detection accuracy of the detection device, reduces the frequency of equipment debugging, and the single-point detection method of the main pipe reduces the number of detectors to be deployed, reduces equipment investment costs, and improves the economy and practicality of the detection process.

[0037] Step 204: Based on the detected particle size, the frequency of the alternating electric field is controlled by the PLC controller to adjust the particle size of the atomized particles after atomization.

[0038] For a description of step 204, please refer to the description of step 104 in the above embodiment. This embodiment will not repeat the details further.

[0039] Step 205: The atomized coal-containing wastewater is sprayed onto the center of one side of the dust cover on the top of the coal conveyor belt using an ultrasonic atomizing nozzle. The water pressure of the ultrasonic atomizing nozzle is 0.05 MPa, and the particle size of the atomized particles is between 0.2 μm and 0.6 μm.

[0040] In some embodiments, the coal-containing wastewater, after atomization and fragmentation treatment, is stably transported to an ultrasonic atomizing nozzle. This nozzle is precisely positioned and fixed at the center of one side of the dust cover on top of the coal conveyor belt. This position directly faces the core area where dust is generated and diffused during the operation of the conveyor belt, allowing the atomized coal-containing wastewater sprayed by the nozzle to radiate the entire dust-generating area around the dust cover at an optimal diffusion angle, maximizing the contact probability between atomized particles and suspended coal dust. During the spraying of the atomized coal-containing wastewater, the working water pressure of the ultrasonic atomizing nozzle is precisely controlled at 0.05 MPa. This water pressure value is highly compatible with the spraying characteristics of the ultrasonic atomizing nozzle, providing sufficient and stable power for the spraying of the atomized coal-containing wastewater, ensuring that the dry fog spray range can comprehensively and evenly cover the dust-generating area, while preventing the already formed fine atomized particles from agglomerating due to excessive water pressure, avoiding large droplets that would affect coal conveying operations and reduce dust suppression effects. At the same time, the low water pressure setting also effectively reduces energy consumption in the spraying process. The atomized particles of coal-containing wastewater finally sprayed by the ultrasonic atomizing nozzle have a particle size precisely controlled between 0.2um and 0.6um. The atomized particles in this particle size range match the particle size of coal dust particles generated by the coal conveying system, and can fully and efficiently contact, collide and adsorb with the coal dust suspended in the air, quickly promoting the formation of solid-liquid aggregates of coal dust.

[0041] Figure 3 A schematic flowchart of another method for suppressing coal conveying dust provided in this application embodiment includes the following steps: Step 301: Magnetize the coal-containing wastewater to reduce its surface tension and dynamic viscosity.

[0042] For a description of step 301, please refer to the description of step 101 in the above embodiment. This embodiment will not repeat the description in detail.

[0043] Step 302: Before the coal-containing wastewater is atomized and crushed by the electric standing wave generator, the coal-containing wastewater is transported to the coal-containing wastewater main pipe and branch pipes by the coal-containing wastewater lift pump at a pressure of 0.2 MPa.

[0044] In some embodiments, before magnetization treatment and subsequent atomization and crushing operations of the electric standing wave generator on the coal-containing wastewater, the coal-containing wastewater is first extracted and pressurized by a coal-containing wastewater booster pump. The inlet of the coal-containing wastewater booster pump is connected to the coal-containing wastewater collection area. The power output of the booster pump is used to precisely pressurize the extracted coal-containing wastewater, and the overall delivery pressure is stably controlled at 0.2 MPa. This pressure value is highly compatible with the operating conditions of the coal-containing wastewater delivery pipeline and subsequent treatment equipment. It can provide sufficient and stable power for the flow of coal-containing wastewater, ensuring that the wastewater can be continuously and smoothly propelled in the pipeline, without causing pipeline impact or loosening of equipment connections due to excessive pressure, or causing the water flow rate to be too slow or water to stagnate in the pipeline or equipment due to insufficient pressure. The coal-containing wastewater, pressurized to 0.2 MPa by the booster pump, is first uniformly transported to the coal-containing wastewater main pipe, achieving centralized collection and overall distribution of the coal-containing wastewater. Then, the coal-containing wastewater main pipe distributes the coal-containing wastewater evenly to each coal-containing wastewater branch pipe according to the actual needs of subsequent treatment. This ensures that the coal-containing wastewater in each branch pipe maintains a stable pressure and flow rate, ensuring smooth flow of the coal-containing wastewater from collection to transportation. This provides a stable material transportation foundation for subsequent processes such as particle size detection, magnetization treatment, and atomization crushing, allowing each treatment stage to be carried out in an orderly manner based on stable water flow conditions.

[0045] Step 303: An alternating electric field is applied to the magnetized coal-containing wastewater using an electric standing wave generator to generate standing wave resonance, causing the coal-containing wastewater to atomize and break up.

[0046] Step 304: Detect the particle size of particulate matter in coal-containing wastewater.

[0047] Step 305: Based on the detected particle size, the frequency of the alternating electric field is controlled by the PLC controller to adjust the particle size of the atomized particles after atomization.

[0048] Step 306: Spray the atomized coal-containing wastewater onto the dust-generating area of ​​the coal conveyor belt to suppress dust.

[0049] For a description of steps 303-306, please refer to the description of steps 102-105 in the above embodiment. This embodiment will not repeat these steps in detail.
