Description

Technical Field

[0001] The present invention relates to the technical field of dust suppressant spraying, and in particular to a dust suppressant spraying system dynamically regulated based on environmental parameters. Background Art

[0002] The severity of dust pollution: During open-air transportation of coal (especially open-air transportation by railways and highways), airflow disturbance causes coal dust to fly, resulting in three major problems: environmental pollution: dust spreads into the atmosphere, polluting the ecology along the line; resource waste: the average annual coal loss reaches 3% to 5% of the total transportation volume; equipment loss: dust compacts the railway track bed, blocks locomotive filters and insulation nets, and poses a safety hazard.

[0003] In related technologies, traditional spraying equipment adopts a fixed spraying mode, which cannot adapt to changes in the ratio of dust suppressants (such as viscosity changes caused by differences in the water-based / oil-based ratio), the dust monitoring and spraying execution systems are separated, and there is a lack of real-time closed-loop control (such as the response delay is greater than 5 minutes when the PM10 concentration suddenly increases), and the equipment selection relies on manual experience, which easily leads to a mismatch between the atomized particle size and the dust particle size. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0005] To this end, an embodiment of the present invention proposes a dust suppressant spraying system based on dynamic regulation of environmental parameters. The spraying system can adjust the ratio of dust suppressants according to actual needs, reduce resource waste, and improve coal utilization during transportation.

In the first spraying state, the spray volume of the atomizing nozzle is greater than or equal to 1.5 L / min·m and less than or equal to 2 L / min·m. In the second spraying state, the spray volume of the atomizing nozzle is 1 to 2 times that of the atomizing nozzle in the first spraying state. In the third spraying state, the spray pressure of the atomizing nozzle is between 0.8 MPa and 1.2 MPa.

[0008] A first monitoring component is electrically connected to the atomizing component and is used to monitor the ambient wind speed.

[0009] When the ambient wind speed is less than 3m / s, the atomizing nozzle is in the first spraying state.

[0010] When the ambient wind speed is greater than or equal to 3m / s and less than 8m / s, the atomizing nozzle is in the second spraying state.

[0011] When the ambient wind speed is greater than or equal to 8 m / s, the atomizing nozzle is in the third spraying state.

[0012] The dust suppressant spraying system, based on dynamic environmental parameter control, uses dynamic control to enable the atomizing nozzle to select the appropriate spraying mode based on ambient wind speed, ensuring a more accurate match between the atomized particle size and the dust particle size, thereby improving dust suppression efficiency. Furthermore, by precisely controlling the spray volume and pressure, equipment losses caused by overspray or uneven spraying, such as nozzle blockage and filter damage, are reduced.

[0013] In some embodiments, the atomizing nozzle includes a nozzle base and a nozzle body, the lower end of the nozzle body is connected to the nozzle base, and the upper end of the nozzle body has a first spraying portion and a second spraying portion, the first spraying portion is used to spray the dust suppressant in a circular shape toward the circumference of the nozzle body, and the second spraying portion is used to spray the dust suppressant in a fan shape toward the circumference of the nozzle body.

[0014] In the first spraying state and the second spraying state, the first spraying part sprays the dust suppressant;

[0015] In the third spraying state, the second spraying unit sprays the dust suppressant.

[0016] In some embodiments, the nozzle body is rotatable around a first axial direction, and the first axial direction is consistent with the up-down direction. In the third spraying state, the second spraying portion is directed in an upwind direction.

[0017] In some embodiments, in the third spraying state, an angle between the direction of the second spraying portion and the wind speed direction is greater than or equal to 15° and less than or equal to 30°.

[0020] The ambient dust concentration is greater than 150 μg / m 3 , the atomizing nozzle is in the third spraying state;

[0021] The ambient dust concentration is less than 50 μg / m 3 , the atomizing nozzle is in the first spraying state or in the second spraying state.

[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] like Figure 1-Figure 3 As shown, the dust suppressant spraying system based on dynamic regulation of environmental parameters according to an embodiment of the present invention includes: an atomization component 1 and a first monitoring component 2.

[0039] The atomizing assembly 1 includes an atomizing nozzle 11, which includes a first spraying state, a second spraying state and a third spraying state. In the first spraying state, the spray volume of the atomizing nozzle 11 is greater than or equal to 1.5 L / min·m and less than or equal to 2 L / min·m. In the second spraying state, the spray volume of the atomizing nozzle 11 is 1 to 2 times that of the atomizing nozzle 11 in the first spraying state. In the third spraying state, the spray pressure of the atomizing nozzle 11 is between 0.8 MPa and 1.2 MPa.

[0040] The first monitoring component 2 is electrically connected to the atomizing component 1. The first monitoring component 2 is used to monitor the ambient wind speed. When the ambient wind speed is less than 3m / s, the atomizing nozzle 11 is in the first spraying state; when the ambient wind speed is greater than or equal to 3m / s and less than 8m / s, the atomizing nozzle 11 is in the second spraying state; when the ambient wind speed is greater than or equal to 8m / s, the atomizing nozzle 11 is in the third spraying state.

[0041] Specifically, if Figure 1-Figure 3 As shown, both the atomizing assembly 1 and the first monitoring assembly 2 can be secured above the coal conveyor track 100 via a mounting bracket 200, allowing for the spraying of dust suppressants on the conveyed coal in response to changes in the conveying environment. The atomizing assembly 1 and the first monitoring assembly 2 are electrically connected to enable real-time data transmission and dynamic adjustment of spray control.

[0042] It is understood that the first monitoring component 2 is responsible for monitoring the ambient wind speed and transmitting the wind speed data to the control system. Based on the wind speed data, the control system instructs the atomizing nozzle 11 in the atomizing component 1 to switch to the corresponding spraying state under different wind speed conditions.

[0043] In other words, the first monitoring component 2 can monitor the ambient wind speed in real time, ensuring that the spraying state of the atomizing nozzle 11 adapts to the actual environment, avoiding the response delay of traditional equipment when the wind speed changes. Through real-time closed-loop control, when the PM10 concentration suddenly increases, the system can respond quickly and adjust the spraying state to effectively suppress dust dispersion.

[0044] That is, the dust suppressant spraying system based on dynamic regulation of environmental parameters according to the embodiment of the present invention is adaptable to different wind speed conditions:

[0045] When the ambient wind speed is less than 3 m / s, the atomizing nozzle 11 is in the first spraying state, and the spray volume is moderate, which not only ensures the dust suppression effect but also avoids the waste of resources caused by excessive spraying.

[0046] When the ambient wind speed is greater than or equal to 3 m / s and less than 8 m / s, the atomizing nozzle 11 switches to the second spraying state, and the spray volume increases to cope with stronger wind disturbances.

[0047] When the ambient wind speed is greater than or equal to 8 m / s, the atomizing nozzle 11 enters the third spraying state, and the spray pressure is further increased to ensure that dust can still be effectively suppressed under strong wind conditions.

[0048] Thus, the dust suppressant spraying system based on dynamic environmental parameter control in the embodiment of the present invention dynamically controls the atomizing nozzle 11 to select the appropriate spraying mode based on the ambient wind speed, ensuring a better match between the atomized particle size and the dust particle size, thereby improving dust suppression efficiency. Furthermore, by precisely controlling the spray volume and pressure, equipment losses caused by excessive or uneven spraying, such as nozzle blockage and filter damage, are reduced.

[0049] It should be noted that the first monitoring component 2 may be an ultrasonic anemometer to achieve three-dimensional vector measurement and also have the ability to resist electromagnetic interference.

[0050] In some embodiments, the atomizing nozzle 11 includes a nozzle base 111 and a nozzle body 112. The lower end of the nozzle body 112 is connected to the nozzle base 111, and the upper end of the nozzle body 112 has a first spraying portion 1121 and a second spraying portion 1122. The first spraying portion 1121 is used to spray the dust suppressant in a circular shape toward the circumference of the nozzle body 112, and the second spraying portion 1122 is used to spray the dust suppressant in a fan shape toward the circumference of the nozzle body 112. In the first spraying state and the second spraying state, the first spraying portion 1121 sprays the dust suppressant; in the third spraying state, the second spraying portion 1122 sprays the dust suppressant.

[0051] Specifically, if Figure 1-Figure 3As shown, the atomizing nozzle 11 consists of a nozzle base 111 and a nozzle body 112. The lower end of the nozzle body 112 is connected to the nozzle base 111 to ensure stable installation of the nozzle. The upper end of the nozzle body 112 is provided with a first spraying portion 1121 and a second spraying portion 1122, which are responsible for dust suppression operations in different spraying modes respectively.

[0052] like Figure 1-Figure 3 As shown, the first spraying portion 1121 is located above the second spraying portion 1122, and the first spraying portion 1121 can spray the dust suppressant in a circular pattern toward the circumference of the nozzle body 112. This spraying pattern is suitable for conditions with low wind speeds, can evenly cover the dust suppression area, and effectively control dust.

[0053] The second spraying portion 1122 sprays the dust suppressant in a fan-shaped pattern toward the circumference of the nozzle body 112 (i.e., the second spraying portion 1122 has a fan-shaped spraying port to make the spray liquid spray more concentrated). This spraying mode is suitable for conditions with high wind speeds, as fan-shaped spraying can expand coverage and enhance dust suppression effects.

[0054] By combining two spraying modes, the system can adapt to a wider range of wind speed variations, ensuring effective dust suppression in diverse environmental conditions. The spraying system intelligently selects the appropriate spraying mode based on real-time wind speed data, eliminating the need for manual intervention and enhancing the automation and intelligence of the dust suppression system. Furthermore, by precisely controlling the spraying mode, unnecessary spraying is reduced, minimizing the impact on the surrounding environment and minimizing the loss of coal resources during transportation.

[0055] In some embodiments, the nozzle body 112 is rotatable around a first axial direction, and the first axial direction is consistent with the up-down direction. In the third spraying state, the second spraying portion 1122 is directed against the wind.

[0056] It can be understood that the nozzle base 111 is connected to the lower end of the nozzle body 112, and a driving structure capable of driving the nozzle body 112 to rotate can be provided inside the nozzle base 111, such as a combination structure of a motor and a gear transmission, so that the nozzle body 112 can realize the rotation function under the action of the driving structure.

[0057] That is, the rotatable nature of the nozzle body 112 allows the system to adjust the spraying angle according to environmental conditions and wind speed to achieve the best dust suppression effect. In the third spraying state, spraying against the wind helps to spray the dust suppressant directly onto the dust blown by the wind, thereby more effectively capturing and reducing the dust.

[0058] In other words, under strong wind conditions, spraying in the direction against the wind can act more directly on the dust blown by the wind, increasing the probability of contact between the dust suppressant and the dust, thereby enhancing the dust suppression effect. The rotatability of the nozzle body 112 allows the system to quickly respond to environmental changes, adjust the spraying direction and angle, and adapt to different wind speed and wind direction conditions. By precisely controlling the spraying direction, the amount of dust suppressant used can be reduced, over-spraying can be avoided, and the use of resources can be optimized. Spraying against the wind helps to concentrate the dust suppressant near the pollution source, reduce the impact on the surrounding environment, and reduce environmental pollution. Combined with environmental monitoring data, the system can automatically adjust the rotation angle and spraying direction of the nozzle body 112 to achieve automated and intelligent dust suppression operations.

[0059] Preferably, in the third spraying state, the angle between the direction of the second spraying portion 1122 and the wind speed direction is greater than or equal to 15° and less than or equal to 30°.

[0060] Specifically, if Figure 2 As shown, the angle α between the direction of the second spraying unit 1122 and the wind speed direction is 15°≤α≤30°. This means that in strong winds, spraying against the wind may cause the dust suppressant to be blown away by the wind, affecting the dust suppression effect. Therefore, by adjusting the angle between the spraying direction and the wind direction, it is possible to reduce resource waste while maintaining dust suppression effectiveness.

[0061] It can be understood that in the third spraying state, that is, when the ambient wind speed is greater than or equal to 8m / s, the spraying direction of the second spraying part 1122 is set to an angle greater than or equal to 15° and less than or equal to 30° with the wind speed direction. This can not only enable the dust suppressant to effectively cover the dust blown by the wind, but also avoid the loss of dust suppressant caused by spraying against the wind.

[0062] In some embodiments, the second spraying portion 1122 further includes an angle adjustment member, which is used to adjust the fan-shaped spraying angle of the second spraying portion 1122 , and the fan-shaped spraying angle is greater than or equal to 60° and less than or equal to 90°.

[0063] As can be appreciated, as shown, the second spraying unit 1122 includes an angle adjustment member that adjusts the fan-shaped spray angle to accommodate varying wind speeds and dust suppression requirements. The fan-shaped spray angle is set to be greater than or equal to 60° and less than or equal to 90°. This range ensures sufficient spray coverage while maintaining spray concentration and efficiency.

[0064] In other words, the angle adjustment allows the operator or system to adjust the spray angle according to environmental parameters (such as wind speed, wind direction and dust concentration) to achieve the best dust suppression effect. In the third spraying state, by adjusting the fan-shaped spray angle, it can ensure that the dust suppressant can effectively cover a larger area and capture more dust in strong wind conditions.

[0065] In some embodiments, the dust suppressant spraying system based on dynamic regulation of environmental parameters of the embodiment of the present invention further includes a second monitoring component 3, the second monitoring component 3 is electrically connected to the atomizing component 1, and the second monitoring component 3 is used to detect the ambient dust concentration. The ambient dust concentration is greater than 150 μg / m 3 , the atomizing nozzle 11 is in the third spraying state; the ambient dust concentration is less than 50μg / m 3 , the atomizing nozzle 11 is in the first spraying state or the second spraying state.

[0066] It is understandable that if Figure 1-Figure 3 As shown, the second monitoring assembly 3 is fixed to the fixing frame 200 and electrically connected to the atomizing assembly 1, and is used to monitor the dust concentration in the environment in real time. The system dynamically adjusts the spraying state of the atomizing nozzle 11 based on the dust concentration data provided by the second monitoring assembly 3 and the ambient wind speed data provided by the first monitoring assembly 2.

[0067] That is to say, when the ambient dust concentration is greater than 150μg / m 3 When the monitoring system determines that the pollution is serious, the atomizing nozzle 11 switches to the third spraying state and performs dust suppression at the maximum spray pressure and spraying volume. 3 When the system determines that the pollution state is slight, the atomizing nozzle 11 can be in the first spraying state or the second spraying state, and the spraying mode is adjusted according to the wind speed.

[0068] Therefore, by monitoring dust concentration in real time, the system can precisely control the spraying of dust suppressants, spraying only when needed and reducing resource waste. When dust concentration is high, the system automatically switches to high-efficiency spraying mode, rapidly reducing dust concentration and improving dust suppression efficiency. Adjusting the spraying mode based on dust concentration avoids overspraying of dust suppressants when dust concentration is low, saving resources. Precise spraying control reduces the environmental impact of dust suppressants, especially in sensitive areas, helping to protect the environment. By integrating multiple environmental parameters and automatically adjusting the spraying strategy, the system achieves intelligent and automated dust suppression.

[0069] It should be noted that the second monitoring component 3 can be a dust monitoring device, such as a laser radar scatterometer, a beta-ray absorption meter, etc.

[0070] In some embodiments, the atomizing assembly 1 further includes a liquid storage tank 12 and a water replenishing tank 13. The liquid storage tank 12 is used to store dust suppressant. The liquid storage tank 12 is connected to the atomizing nozzle 11. The water replenishing tank 13 is connected to the outlet of the liquid storage tank 12. The water replenishing tank 13 is used to mix clean water with the dust suppressant discharged from the liquid storage tank 12 to dilute the concentration of the dust suppressant.

[0071] It is understandable that if Figure 1-Figure 3 As shown, the liquid storage tank 12 is used to store concentrated dust suppressant. The water supply tank 13 is connected to the outlet of the liquid storage tank 12 through a pipe, and is used to add clean water to the discharged dust suppressant to adjust the concentration of the dust suppressant. The liquid storage tank 12 is connected to the atomizing nozzle 11 through a pipe to ensure the supply of dust suppressant. In other words, the water supply tank 13 can dynamically adjust the concentration of the dust suppressant by adding clean water to the dust suppressant discharged from the liquid storage tank 12 to meet different spraying requirements. The system can automatically adjust the water supply rate of the water supply tank 13 according to environmental parameters (such as wind speed and dust concentration) to achieve dynamic dilution of the dust suppressant.

[0072] In other words, the system can flexibly adjust the concentration of dust suppressant based on actual environmental conditions to meet varying dust suppression needs and enhance dust suppression effectiveness. Dynamically diluting the dust suppressant allows for more efficient use, avoiding overuse and waste. The system automatically adjusts the concentration of dust suppressant based on environmental parameters, adapting to varying wind speeds and dust concentrations for precise dust suppression.

[0073] In some embodiments, the dust suppressant spraying system based on dynamic regulation of environmental parameters of an embodiment of the present invention also includes a third monitoring component 4, which is electrically connected to the atomizing component 1. The third monitoring component 4 is used to monitor the ambient humidity. When the ambient humidity is less than 40%, the water replenishment tank 13 introduces clean water into the dust suppressant to dilute the dust suppressant; when the ambient humidity is greater than 70%, the spraying frequency of the atomizing nozzle 11 is reduced.

[0074] It is understandable that if Figure 1-Figure 3 As shown, the third monitoring component 4 is responsible for real-time monitoring of the ambient humidity. Based on the humidity data provided by the third monitoring component 4, the system dynamically adjusts the water replenishment rate of the water replenishment tank 13 and the spraying frequency of the atomizing nozzle 11.

[0075] When the ambient humidity is less than 40%, the system identifies the environment as dry. The water tank 13 increases the amount of fresh water introduced into the dust suppressant to dilute the agent, increase the humidity of the spray liquid, and enhance the dust suppression effect. When the ambient humidity is greater than 70%, the system identifies the environment as humid and reduces the spraying frequency of the atomizing nozzle 11 to avoid excessive humidity and waste of dust suppressant due to overspraying.

[0076] It should be noted that the third monitoring component 4 can be a temperature and humidity transmitter.

[0077] In some embodiments, the dust suppressant spraying system based on dynamic regulation of environmental parameters of an embodiment of the present invention also includes a first detection component, which is connected to the liquid storage tank 12, and a portion of the first detection component is placed inside the liquid storage tank 12 for detecting the dynamic viscosity of the dust suppressant.

[0078] It is understandable that if Figure 1-Figure 3As shown, the first detection component is connected to the liquid storage tank 12 and partially positioned within the tank 12, allowing for direct contact and monitoring of the dust suppressant's viscosity. Based on the viscosity data provided by the first detection component, the system dynamically adjusts the spraying parameters of the atomizing nozzle 11, such as spray volume and spray pressure. In other words, the first detection component monitors changes in the dust suppressant's viscosity in real time and transmits this data to the control system. Based on this dust suppressant viscosity data, the control system adjusts the spraying state of the atomizing nozzle 11 to accommodate the spraying requirements at varying viscosities.

[0079] In other words, by monitoring the viscosity of the dust suppressant, the system ensures uniformity and stability in the spray solution, thereby improving spraying effectiveness. The viscosity of the dust suppressant may vary at different temperatures or mixing ratios, and the system automatically adjusts the spraying parameters to accommodate these changes. Real-time viscosity monitoring helps prevent nozzle clogging and uneven spraying, improving system reliability and stability.

[0080] It should be noted that the first detection component 5 can be a dust suppressant analysis device, such as an online viscometer, a surface tension sensor, etc.
