Description

Technical Field

[0001] This utility model relates to the field of dust suppressant spraying technology, specifically to a dust suppressant spraying system based on dynamic control of environmental parameters. Background Technology

[0002] The severity of dust pollution: During open-air transportation of coal (especially open-air transportation by rail and road), coal dust is blown around due to airflow disturbances, causing three major problems: Environmental pollution: Dust spreads into the atmosphere, polluting the ecology along the route; Resource waste: The average annual coal loss reaches 3% to 5% of the total transportation volume; Equipment wear and tear: Dust caking the railway track bed, clogging locomotive filters and insulation nets, causing safety hazards.

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

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of this utility model propose a dust suppressant spraying system based on dynamic control of environmental parameters. This spraying system can adjust the ratio of dust suppressant according to actual needs, reduce resource waste, and improve coal utilization during transportation.

[0006] The dust suppressant spraying system based on dynamic control of environmental parameters according to an embodiment of the present invention includes:

[0007] An atomizing assembly includes an atomizing nozzle, which has 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 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, electrically connected to the atomizing component, is used to monitor ambient wind speed.

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

[0010] When the ambient wind speed is greater than or equal to 3 m / s and less than 8 m / 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 of this invention allows the atomizing nozzle to select an appropriate spraying state according to the ambient wind speed, resulting in a better match between the atomized particle size and the dust particle size, thus improving dust suppression efficiency. Furthermore, by precisely controlling the spray volume and spray pressure, it reduces equipment wear caused by over-spraying or uneven spraying, such as nozzle clogging and filter damage.

[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 section and a second spraying section. The first spraying section is used to spray dust suppressant in a circular manner around the nozzle body, and the second spraying section is used to spray dust suppressant in a fan-shaped manner around the nozzle body.

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

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

[0016] In some embodiments, the nozzle body is rotatable about a first axis, and the first axis is consistent with the up and down direction. In the third spraying state, the second spraying part is oriented against the wind.

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

[0018] In some embodiments, the second spraying unit further includes an angle adjusting member, which is used to adjust the fan-shaped spraying angle of the second spraying unit, wherein the fan-shaped spraying angle is greater than or equal to 60° and less than or equal to 90°.

[0019] In some embodiments, the dust suppressant spraying system based on dynamic control of environmental parameters according to this utility model further includes a second monitoring component, which is electrically connected to the atomizing component and is used to detect the concentration of environmental dust.

[0020] The environmental dust concentration is greater than 150 μg / m³ 3 The atomizing nozzle is in the third spraying state;

[0021] The ambient dust concentration is less than 50 μg / m³. 3 The atomizing nozzle is in either the first spraying state or the second spraying state.

[0022] In some embodiments, the atomizing assembly further includes a storage tank and a water replenishment tank. The storage tank is used to store dust suppressant and is connected to the atomizing nozzle. The water replenishment tank is connected to the outlet of the storage tank and is used to mix the dust suppressant discharged into the storage tank with clean water to dilute the concentration of the dust suppressant.

[0023] In some embodiments, the dust suppressant spraying system based on dynamic control of environmental parameters according to this utility model further includes a third monitoring component, which is electrically connected to the atomizing component and is used to monitor ambient humidity.

[0024] When the ambient humidity is less than 40%, the water replenishment tank circulates clean water into the dust suppressant to dilute it.

[0025] If the ambient humidity is greater than 70%, reduce the spraying frequency of the atomizing nozzle.

[0026] In some embodiments, the dust suppressant spraying system based on dynamic control of environmental parameters of this utility model further includes a first detection element, which is connected to the storage tank and a portion of the first detection element is placed inside the storage tank for detecting the dynamic viscosity of the dust suppressant.

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

[0038] like Figures 1-3 As shown, the dust suppressant spraying system based on dynamic control of environmental parameters in this embodiment of the present invention includes: an atomizing component 1 and a first monitoring component 2.

[0039] The atomizing component 1 includes an atomizing nozzle 11, which has 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 3 m / s, the atomizing nozzle 11 is in the first spraying state; when the ambient wind speed is greater than or equal to 3 m / s and less than 8 m / s, the atomizing nozzle 11 is in the second spraying state; when the ambient wind speed is greater than or equal to 8 m / s, the atomizing nozzle 11 is in the third spraying state.

[0041] Specifically, such as Figures 1-3 As shown, both the atomizing component 1 and the first monitoring component 2 can be fixed above the coal conveying track 100 by the fixing bracket 200, so that dust suppressant can be sprayed on the conveyed coal according to changes in the conveying environment during the coal conveying process. The atomizing component 1 and the first monitoring component 2 are electrically connected to realize real-time data transmission and dynamic adjustment of spray control.

[0042] Understandably, 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 nozzles 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 is adapted 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, adjust the spraying state, and effectively suppress dust diffusion.

[0044] That is, the dust suppressant spraying system based on dynamic adjustment of environmental parameters in this embodiment of the invention adapts 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, with a moderate spray volume, which ensures the dust suppression effect while avoiding 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, increasing the spray volume 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 effective dust suppression even under strong wind conditions.

[0048] Therefore, the dust suppressant spraying system based on dynamic control of environmental parameters in this embodiment of the invention allows the atomizing nozzle 11 to select a suitable spraying state according to the ambient wind speed, making the atomized particle size more compatible with the dust particle size and improving dust suppression efficiency. Furthermore, by precisely controlling the spray volume and spray pressure, it reduces equipment wear caused by over-spraying or uneven spraying, such as nozzle clogging and filter damage.

[0049] It should be noted that the first monitoring component 2 can be an ultrasonic anemometer to achieve three-dimensional vector measurement and also has 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 part 1121 and a second spraying part 1122. The first spraying part 1121 is used to spray dust suppressant in a circular manner in the circumferential direction of the nozzle body 112, and the second spraying part 1122 is used to spray dust suppressant in a fan-shaped manner in the circumferential direction of the nozzle body 112. In the first spraying state and the second spraying state, the first spraying part 1121 sprays dust suppressant; in the third spraying state, the second spraying part 1122 sprays dust suppressant.

[0051] Specifically, such as Figures 1-3As 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 section 1121 and a second spraying section 1122, which are responsible for dust suppression operations of different spraying modes, respectively.

[0052] like Figures 1-3 As shown, the first spraying section 1121 is located above the second spraying section 1122, and the first spraying section 1121 can spray dust suppressant in a circular manner around the nozzle body 112. This spraying mode is suitable for situations with low wind speeds, can evenly cover the dust suppression area, and effectively control dust.

[0053] The second spraying section 1122 sprays the dust suppressant in a fan shape around the nozzle body 112 (i.e., the second spraying section 1122 has a fan-shaped spray nozzle to make the spray liquid spray more concentrated). This spraying mode is suitable for situations with high wind speeds, and the fan-shaped spray can expand the coverage area and enhance the dust suppression effect.

[0054] Therefore, by combining the two spraying modes, the system can adapt to a wider range of wind speed variations, ensuring good dust suppression effects under different environmental conditions. The spraying system can intelligently select the appropriate spraying mode based on real-time monitored wind speed data, requiring no manual intervention and improving the automation and intelligence level of the dust suppression system. Furthermore, by precisely controlling the spraying mode, unnecessary spraying is reduced, minimizing the impact on the surrounding environment and reducing the loss of coal resources during transportation.

[0055] In some embodiments, the nozzle body 112 is rotatable about a first axis, and the first axis is consistent with the up and down direction. In the third spraying state, the second spraying part 1122 is oriented against the wind direction.

[0056] It is understood that the nozzle base 111 is connected to the lower end of the nozzle body 112. The nozzle base 111 may have a drive structure inside that can drive the nozzle body 112 to rotate, such as a combination of motor and gear transmission, so that the nozzle body 112 can achieve the function of rotation under the action of the drive structure.

[0057] In other words, the rotatable nature of the nozzle body 112 allows the system to adjust the spray 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 directly spray the dust suppressant onto the dust blown by the wind, thereby more effectively capturing and reducing dust.

[0058] In other words, under strong wind conditions, spraying 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, adjusting the spray direction and angle to adapt to different wind speeds and directions. By precisely controlling the spray direction, the amount of dust suppressant used can be reduced, avoiding over-spraying and thus optimizing resource use. Spraying against the wind helps concentrate the dust suppressant near the pollution source, reducing the impact on the surrounding environment and lowering environmental pollution. Combined with environmental monitoring data, the system can automatically adjust the rotation angle and spray direction of the nozzle body 112 to achieve automated and intelligent dust suppression operation.

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

[0060] Specifically, such as Figure 2 As shown, the angle between the orientation of the second spraying section 1122 and the wind direction is α, where 15°≤α≤30°. This means that under strong wind conditions, spraying against the wind may cause the dust suppressant to be dispersed, affecting the dust suppression effect. Therefore, by adjusting the angle between the spraying direction and the wind direction, the waste of resources can be reduced while ensuring the dust suppression effect.

[0061] Understandably, in the third spraying state, i.e. when the ambient wind speed is greater than or equal to 8 m / s, the spraying direction of the second spraying unit 1122 is set to form an angle greater than or equal to 15° and less than or equal to 30° with the wind speed direction. This can effectively cover the dust blown by the wind with the dust suppressant and avoid the loss of dust suppressant due to spraying against the wind.

[0062] In some embodiments, the second spraying unit 1122 further includes an angle adjusting member for adjusting the fan-shaped spraying angle of the second spraying unit 1122, wherein the fan-shaped spraying angle is greater than or equal to 60° and less than or equal to 90°.

[0063] As can be understood, as shown in the figure, the second spraying unit 1122 includes an angle adjustment component, which can adjust the angle of the fan-shaped spray to adapt to different 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 that the spray coverage area is large enough while maintaining the concentration and efficiency of the spray.

[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 spray state, by adjusting the fan-shaped spray angle, it can be ensured that the dust suppressant can effectively cover a larger area and capture more dust under strong wind conditions.

[0065] In some embodiments, the dust suppressant spraying system based on dynamic control of environmental parameters of this utility model further includes a second monitoring component 3, which is electrically connected to the atomizing component 1. The second monitoring component 3 is used to detect the concentration of environmental dust, where the concentration of environmental dust is greater than 150 μg / m³. 3 Atomizing nozzle 11 is in the third spraying state; the ambient dust concentration is less than 50 μg / m³. 3 The atomizing nozzle 11 is in either the first spraying state or the second spraying state.

[0066] It is understandable that, such as Figures 1-3 As shown, the second monitoring component 3 is fixed on the mounting bracket 200 and electrically connected to the atomizing component 1, and is used to monitor the dust concentration in the environment in real time. Based on the dust concentration data provided by the second monitoring component 3 and the ambient wind speed data provided by the first monitoring component 2, the system dynamically adjusts the spraying state of the atomizing nozzle 11.

[0067] In other words, when the ambient dust concentration is greater than 150 μg / m³ 3 When the monitoring system determines the pollution level to be severe, atomizing nozzle 11 switches to the third spraying mode, using maximum spray pressure and spray volume for dust suppression. When the ambient dust concentration is less than 50 μg / m³... 3 When the system determines that the pollution is slight, the atomizing nozzle 11 can be in either the first or second spraying state, adjusting the spraying mode 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 a high-efficiency spraying mode to quickly reduce dust concentration and improve dust suppression efficiency. Adjusting the spraying status according to dust concentration avoids over-spraying of dust suppressants when dust concentration is low, saving resources. Precise spraying control reduces the environmental impact of dust suppressants, especially in sensitive areas, contributing to environmental protection. 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 lidar scattering instrument or a beta-ray absorber.

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

[0071] It is understandable that, such as Figures 1-3 As shown, the storage tank 12 is used to store concentrated dust suppressant. The water replenishment tank 13 is connected to the outlet of the storage tank 12 via a pipe and is used to add clean water to the discharged dust suppressant to adjust its concentration. The storage tank 12 is connected to the atomizing nozzle 11 via a pipe to ensure the supply of dust suppressant. In other words, by adding clean water to the dust suppressant discharged from the storage tank 12, the water replenishment tank 13 can dynamically adjust the concentration of the dust suppressant to meet different spraying requirements. The system can automatically adjust the water replenishment rate of the water replenishment 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 the dust suppressant according to actual environmental conditions to adapt to different dust suppression needs and improve the dust suppression effect. By dynamically diluting the dust suppressant, it can be used more efficiently, avoiding overuse and waste. The system can automatically adjust the concentration of the dust suppressant according to environmental parameters, adapting to different wind speeds and dust concentrations to achieve precise dust suppression.

[0073] In some embodiments, the dust suppressant spraying system based on dynamic control of environmental parameters of this utility model further 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 it. When the ambient humidity is greater than 70%, the spraying frequency of the atomizing nozzle 11 is reduced.

[0074] It is understandable that, such as Figures 1-3 As shown, the third monitoring component 4 is responsible for real-time monitoring of 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 determines it to be a dry environment. In this case, the water tank 13 will increase the amount of clean water flowing into the dust suppressant to dilute it, increase the humidity of the sprayed liquid, and enhance the dust suppression effect. When the ambient humidity is greater than 70%, the system determines it to be a humid environment. In this case, the system will reduce the spraying frequency of the atomizing nozzles 11 to avoid excessive spraying that would lead to excessively high ambient humidity and waste of dust suppressant.

[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 control of environmental parameters of this utility model further includes a first detection element, which is connected to the storage tank 12, and a portion of the first detection element is placed inside the storage tank 12 for detecting the dynamic viscosity of the dust suppressant.

[0078] It is understandable that, such as Figures 1-3As shown, the first detection element is connected to the storage tank 12, and part of it is placed inside the storage tank 12 to directly contact and monitor the viscosity of the dust suppressant. The system dynamically adjusts the spraying parameters of the atomizing nozzle 11, such as spray volume and spray pressure, based on the viscosity data provided by the first detection element. That is, the first detection element monitors the viscosity changes of the dust suppressant in real time and transmits the data to the control system. The control system adjusts the spraying state of the atomizing nozzle 11 according to the viscosity data of the dust suppressant to adapt to the spraying requirements under different viscosities.

[0079] In other words, by monitoring the viscosity of the dust suppressant, the system can ensure the uniformity and stability of the spray solution, thereby improving the spraying effect. The viscosity of the dust suppressant may vary at different temperatures or mixing ratios, and the system can automatically adjust the spraying parameters to adapt to these changes. Real-time viscosity monitoring helps prevent nozzle clogging or uneven spraying, improving the system's 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 or surface tension sensor.
