DETAILED DESCRIPTION
[0022] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Please see the attached Figure 1 -Attached Figure 3 , an embodiment of the present invention provides a coal turner intelligent dust suppression system, including a coal dust concentration monitoring module, the coal dust concentration monitoring module also includes a dust detector 12, the dust detector 12 is set in the working area of the coal turner; Dry mist dust suppression assembly, the dry mist dust suppression assembly includes a dry mist dust suppression machine 15, an ultrasonic atomizing nozzle 11, a high-pressure variable frequency water pump 2, an air storage tank 6 and an air compressor 5; AI intelligent control module, AI intelligent control module also includes: Data storage unit, accumulating and storing coal dust concentration data; Statistical analysis unit, building a database of coal dust concentration variation characteristics; Deep learning unit, which provides feature database to autonomously optimize dust suppression control; The water-gas distributor 16 is connected to the high-pressure variable frequency water pump 2 and the electric regulating valve 9 through the water-gas pipeline; Winter antifreeze components, winter antifreeze components include: low-temperature constant temperature electric heating tape and temperature sensor; Automatic water replenishment assembly, automatic water replenishment assembly includes a water tank 1, and provided inside the water tank 1 water inlet float valve 17, a water level sensor; Pipeline safety components, including a check valve 3, a butterfly valve 4 and a safety valve 21; Among them, the AI intelligent control module outputs graded control instructions to the high-pressure variable frequency water pump 2 and the electric regulating valve 9 according to the real-time coal dust concentration signal and the coal type characteristic model to control the dry fog water volume.
[0024] Specifically, the dust detector 12 is installed in dust-generating areas such as the dropping point and transfer belt of the coal turner, and can collect PM2.5 and PM10 concentration signals around the dust points in real time. The measured concentration signals can be converted into current signals and transmitted to the AI intelligent control module. The dust detector 12 used in this device is a commonly used dust detector 12 on the market, so its specific structure and principle are not described in detail here. When the AI intelligent control module receives the dust concentration information, it can call the pre-stored coal type database to match the characteristics of the current operating coal type. For example, when lignite and bituminous coal are turned over, the concentration of dust they stir up is different. Then, the dust of different concentrations can be compared with the pre-stored coal type database to obtain the type of coal, which can provide data for its subsequent precise dust suppression. After measuring the dust concentration and type of the coal type, the AI algorithm can be used to realize intelligent graded control of the dry fog water volume based on the concentration difference, and the process of the AI algorithm calculating the water spraying volume is as follows: Real-time collection and preprocessing of coal dust concentration signals; The dust concentration value C is detected in real time by the dust detector 12 t And according to the time interval, extract the peak value C of dust concentration p and mean C a ; Coal type characteristics matching and basic water volume calculation; By identifying the coal type and comparing it with the pre-stored coal type database, the dust generation coefficient K of different coal types can be obtained. d; The calculation formula for basic water volume is: Q b =K d× C a ×A, where A is the dust suppression area correction factor, C a is the mean dust concentration; Refer to Table 1 below for basic water volume: Table 1:
[0025] Refer to Table 2 below for dynamic graded control; Table 2:
[0026] The calculation formula for real-time water spray output is: Q r =α×Q b ; Where α is the water vapor correction coefficient, which increases with the peak value of dust concentration; The concentration feedback value C detected by the dust detector 12 after dust suppression o The dust suppression efficiency evaluation formula is as follows: η = ×100%; If η is less than 90%, the strategy iteration is triggered and the K of the coal type is updated. d The update formula is as follows: K d1 =K d +β×(1-η); Where β is the learning rate, and its initial value is 0.05. When the feature database is updated, a new water volume control can be generated.
[0027] The AI intelligent control module is equipped with an intelligent master control cabinet 14 and is connected to the dust detector 12. The AI intelligent control module controls the electric regulating valve 9 to replenish water according to the signal of the dust detector 12, and links the high-pressure variable frequency water pump 2 to adjust the water pressure. The outside of the intelligent master control cabinet 14 is connected to the signal feedback adjustment line 19.
[0028] Specifically, the intelligent master control cabinet 14 is in the shape of a shell, and the AI intelligent control module is installed inside the intelligent master control cabinet 14. Through the electrical connection between the AI intelligent control module and the dust detector 12, the AI intelligent control module can receive the dust concentration information detected by the dust detector 12, and control the high-pressure variable frequency water pump 2 to autonomously adjust the water pressure according to the type of coal and dust concentration to prevent excessive water mist from being excessively covered, resulting in waste of water mist, or insufficient water mist coverage, resulting in poor dust suppression effect.
[0029] The execution method of the deep learning unit includes the following steps: S1. Extract the distribution characteristics of coal dust concentration in historical operations; S2. Establish a relationship model between coal type characteristics and dust concentration; S3. Dynamically adjust the water and gas volume control parameters through reinforcement learning.
[0030] Specifically, when the dust detector 12 detects the concentration of coal dust and compares it with the type of coal, it can adjust the distribution of water in real time according to the distribution of coal dust in historical operations. For example, different types of coal have different distribution areas of dust concentration. Through the historical operation records of the deep learning unit, the water volume can be increased in the areas with higher concentrations of coal dust, and the water volume can be reduced in the areas with lower concentrations of coal dust, thereby accurately suppressing the coal dust and preventing the waste of water mist. At the same time, through each operation, the distribution of coal dust concentrations of different types of coal can be recorded in real time and the relationship between coal type and dust concentration can be established, which is convenient for subsequent regulation of water volume. Through the above formula, the parameters of water and gas control can also be dynamically adjusted. After continuous optimization and learning, the subsequent automation and flexibility can be increased.
[0031] The water-gas distributor 16 includes a plurality of independent branch pipelines, and each independent pipeline is provided with an electric regulating valve 9 .
[0032] Specifically, the electromagnetic flowmeter 23 can monitor the single-channel water flow in real time, the pressure transmitter 24 can detect the branch pipe air pressure, and the electric regulating valve 9 can adjust the single-channel opening according to the AI instruction, thereby achieving regional differentiated dust suppression and avoiding excessive spraying in low-dust areas.
[0033] The water-gas pipeline includes a water supply main pipe 7 and an air supply main pipe 8 , and a filter 25 is externally provided on the water-gas pipeline. An exhaust valve 13 is connected to the end of the water supply main pipe.
[0034] Specifically, the filter 25 is divided into a precision filter 25 and a fully automatic suction brush filter 25 for dual filtration. The shell of the precision filter 25 is generally made of stainless steel, and a tubular filter element such as a PP filter element is used inside as a filter element. Different filter elements are selected according to different filter media and design processes to meet the requirements of the outlet water quality. It can effectively remove water, oil mist, and solid particles, and effectively remove particles of 0.01μm and above, ensuring the cleanliness of the water supply. The fully automatic brush filter 25 is installed at the outlet of the high-pressure variable frequency water pump 2 to remove fine impurities in the main line. The filtration accuracy is 50μm, which is a fine filtration, which can ensure that the system water quality meets the requirements of dry mist and reduce the occurrence of nozzle clogging. The internal structure of the filter 25 includes a stainless steel wire brush, a stainless steel filter screen and a transmission part. The cleaning and drainage are automatically completed by the transmission motor and the electric valve. The operation mode is automatic operation, and it has a pressure difference or timed automatic drainage function. When water flows through the filter 25, mechanical impurities in the water are intercepted by the filter screen. When the impurities accumulated on the surface of the filter screen increase and the pressure difference reaches 0.05MPa, the pressure difference type pressure difference switch sends a signal, the transmission motor starts, the drainage valve opens, and the impurities deposited in the filter screen are brushed off by the rotating brush, sucked out from the suction port, and then discharged from the drainage port. The entire brushing and drainage process does not require human operation or shutdown. At the same time, the equipment also has timed cleaning and drainage and manual cleaning and drainage functions to ensure the safety and reliability of water output under any circumstances.
[0035] The ultrasonic atomizing nozzle 11 is installed through the universal joint assembly 22 , and the ultrasonic atomizing nozzle 11 has an ultrasonic generator built in.
[0036] Specifically, the universal joint assembly 22 comprises a nozzle, a mounting base, a universal joint, a water inlet pipe, an air inlet pipe, a protective sleeve, and fixing screws. An alloy housing surrounds the nozzle and connects to the water and air pipelines to form the universal joint sprayer assembly. The spherical alloy protective housing adjusts the spray direction and prevents material from directly impacting the nozzle during transport. The nozzle is constructed of a 304 polished stainless steel housing, which is durable, impact-resistant, and corrosion-resistant. The aluminum alloy sphere provides high strength and allows for repeated disassembly, ensuring good flow and resistance to clogging. The ultrasonic atomizing nozzle 11 is equipped with a specially designed titanium alloy ultrasonic generator at the front end of the nozzle. The energy generated by the high-speed impact of the fluid on the titanium metal is used to make the titanium alloy ultrasonic generator emit high-frequency vibrations. The originally atomized droplets are micro-atomized again after being subjected to the high-frequency ultrasonic vibrations. This design can not only produce extremely small atomized particles, but also the spray particle size produced by the ultrasonic atomizing nozzle 11 is more uniform and consistent compared with the general air-assisted nozzle. The atomization process of the ultrasonic atomizing nozzle 11 can be divided into two stages. In the first stage, the liquid is first mixed with compressed air to produce fine atomized droplets that are sprayed out of the nozzle. When the atomized droplets hit the ultrasonic generator at the front end of the nozzle, they are immediately micro-atomized into smaller droplets, which is called the second stage. Through the cooperation of the ultrasonic atomizing nozzle 11 and the universal joint assembly 22, the flexibility of spraying water mist can be greatly increased, and the dust suppression effect is increased.
[0037] Steps for winterizing components include: D1. When the temperature sensor detects that the ambient temperature is lower than the set threshold, the low-temperature constant temperature electric heating tape is started.
[0038] Specifically, when used in winter, the temperature sensor can detect the ambient temperature. When the temperature environment is lower than the threshold, the electric heating tape can be powered on through the controller, thereby ensuring the normal use of the equipment. The relevant means of transmitting temperature information through the temperature sensor and controller of this equipment are relatively mature in the existing technology, so its specific structure and principle will not be elaborated here.
[0039] The steps for replenishing water of the automatic water replenishment component include: B1. When the water level sensor detects that the liquid level in the water tank 1 drops to a first threshold, the water inlet float valve 17 is opened; B2, high-pressure variable frequency water pump 2 reduces the frequency to the base frequency to maintain the basic water pressure; B3. When the liquid level rises to the second threshold, the water inlet float valve 17 is closed and the frequency of the high-pressure variable frequency water pump 2 is restored.
[0040] Specifically, the water level sensor and the water inlet float valve 17 can cooperate to detect the liquid level inside the water tank 1. When the water level is lower than the set threshold, the water inlet float valve 17 can be opened to replenish water into the water tank 1. Synchronously, the high-pressure variable frequency water pump 2 can reduce the frequency to maintain the basic water pressure. When the water level inside the water tank 1 reaches the second threshold, the water inlet float valve 17 can be closed to stop water inlet, and the frequency of the high-pressure variable frequency water pump 2 can be restored, thereby achieving an energy-saving effect.
[0041] In order to more intuitively see the technical effects of the above technical solutions, they are integrated with actual application scenarios, as shown in Table 3 below: Table 3: Application Scenario Workflow Technical Effects Dust suppression operations Dust detector 12 → deep learning unit → three-level water flow control Increase dust suppression and water saving effects Low temperature operation Temperature sensor → Electric heating Prevent water mist from freezing and can be used normally in low temperature environment Operation in narrow environments Universal joint assembly 22 adjustment + dry mist directional spray Cover dead corners and increase dust suppression angle Switching of coal types Coal type identification → Feature database matching → Dynamic adjustment of water-gas ratio Flexible switching of dust suppression water distribution according to coal type Unattended situation Water level sensor → water inlet float valve 17 + high-pressure variable frequency water pump 2 linkage Reduced labor costs
[0042] Furthermore, the core components of this system also include a water and air piping system and a spray box. The water piping system is connected from outside the dumper room. To accommodate the dumper's rotation and material distribution, a water piping adapter system is installed on the dumper. This allows the pipeline to rotate with the dumper without twisting, ensuring water supply at the terminal. The air piping system is connected to the air compressor 5 outside the yard, leading from the stacker to a rotary joint and then connected to the main machine. The spray box is composed of a nozzle, a nozzle fixing seat, a water distribution pipe, an air distribution pipe, and insulation materials. The spray box is equipped with multiple nozzles at the same time. The spray box body is made of aluminum alloy. There are water, air, and electric heating tape interfaces at both ends of the box, which are connected to the main pipeline through a hose. The high-pressure variable frequency water pump 2 controls and adjusts the water flow rate through the linkage of variable frequency high-pressure device equipment and detection data, thereby achieving the water volume and water pressure standards required by the dry fog dust suppression system and ensuring the dry fog dust suppression effect; The water-gas distributor 16 realizes the connection of the water, gas and electricity main lines with the universal joint spray box assembly through the water-gas distributor 16, and realizes the spraying of each universal joint spray box assembly separately through PLC control according to the on-site situation; The principle of dry fog generation is that compressed air and water enter the nozzle through the nozzle's air and water inlets, respectively, and converge at the nozzle's internal outlet. Due to the nozzle's special design, the compressed air velocity at the nozzle outlet exceeds the speed of sound, generating a sonic boom. The energy of the sonic boom explodes the water into relatively small mist particles, which then enter the resonance chamber. The resonator in the resonance chamber reflects the sonic boom energy and the shock wave of the compressed air, generating a strong shock wave that explodes the smaller mist particles again, producing a dense mist of 1-10μm in diameter that is ejected. Dry fog dust suppression utilizes extremely fine "mist droplets" at the micron level, which are more effective at capturing fine particulate matter than conventional water spray dust removal. Dry fog is sprayed directly into dust-generating areas, using the small droplets to atomize quickly to increase the water vapor saturation concentration in the dusty area. Using coal dust as condensation nuclei, the microphysical process of agglomeration and fusion is rapidly completed, achieving dust reduction.
[0043] Example: Aiming at the operational characteristics of coal turners, a spray dust suppression method is used. Through the precise response mechanism of the real-time coal dust concentration monitoring system, the dust concentration detection signal during coal turner operation is deeply coupled with the dry mist dust suppression device, achieving precise synchronous control of both operation and dust suppression. Based on an intelligent decision-making model of coal quality characteristics, an AI algorithm is used to achieve intelligent graded control of dry mist water vapor according to the differences in dust concentration of different coal types. The system collects real-time coal dust concentration monitoring data after dust suppression operations, accumulates and stores data through a data cache module, and uses a statistical analysis engine to perform multi-dimensional processing on historical data to build a database of coal dust concentration variation characteristics. Based on massive monitoring data, the AI intelligent control module uses a deep learning algorithm to autonomously learn and optimize dust suppression control strategies. By dynamically adjusting control parameters and regulation logic, and continuously iterating and updating the control and regulation algorithm, it achieves adaptive adjustment and precise control of dust suppression operation parameters, ultimately forming a closed-loop optimized dust suppression intelligent control system. The system is equipped with two high-pressure variable-frequency water pumps and automatic water replenishment, achieving intelligent and efficient operation throughout the entire process, allowing for unattended operation. The research and development process focused on intelligent calculation of water consumption for different coal types. The dry mist dust suppression system incorporates winter antifreeze measures to ensure the proper operation of all functional systems. All pipelines are insulated with low-temperature, constant-temperature electric heating cables for frost protection, ensuring year-round operation.
