[0032] Dust monitoring sensors are installed in target areas (such as rubber transport lanes under coal mines) to monitor the dust concentration and particle size distribution in the area in real time. Dust monitoring sensors use high-precision, multi-parameter measurement technology to accurately obtain key data such as dust concentration and particle size.

[0033] S2: Data transmission and analysis

[0034] The data acquired by the dust monitoring sensor is transmitted to the intelligent control system. The intelligent control system has a built-in high-performance data processing module that can quickly and accurately analyze and process the received data and identify the dust particle size distribution in the current environment.

[0035] S3: Parameter adjustment

[0036] The intelligent control system analyzes the dust particle size distribution data according to the preset algorithm and automatically adjusts the parameters of the spray system accordingly. The specific adjustments include the spray pressure and nozzle type to ensure that the droplet size produced matches the dust particle size and improve the dust reduction efficiency.

[0037] S4: Droplet size adjustment

[0038] The spray system includes components such as a high-pressure pump, an adjustable nozzle and a flow control valve. The adjustable nozzle is specially designed to produce droplets of different sizes at different spray pressures. The intelligent control system adjusts the droplet size in real time by controlling the output pressure of the high-pressure pump and adjusting the nozzle type to meet the dust reduction requirements of dust of different particle sizes.

[0039] S5: Real-time response and adjustment

[0040] When the dust concentration or particle size distribution changes, the dust monitoring sensor can quickly sense and transmit new data to the intelligent control system. The intelligent control system quickly responds and adjusts the spray parameters through linkage, such as increasing or decreasing the injection pressure, changing the nozzle type, etc., to maintain efficient dust reduction effect.

[0041] 2. Device composition

[0042] The device of the present invention mainly comprises components such as a dust monitoring sensor, an intelligent control system, a spray system and a particle size adjustment nozzle.

The control module issues control instructions based on the analysis results and automatically adjusts the parameters of the spray system, including the injection pressure and nozzle type. In addition, the intelligent control system also has remote monitoring and fault diagnosis functions to ensure the stable operation of the device.

[0047] Spray system

[0048] The spray system includes components such as a high-pressure pump, an adjustable nozzle and a flow control valve. The high-pressure pump provides stable water pressure, and the adjustable nozzle adjusts the spray pressure and nozzle type according to the instructions of the intelligent control system to produce droplets that match the dust particle size. The flow control valve is used to control the spray volume and ensure the spray effect.

[0049] Particle size adjustment nozzle

A pressure sensor and nozzle valve are installed inside the nozzle to adjust the injection pressure and droplet size in real time. Through the instructions of the intelligent control system, the particle size adjustment nozzle can quickly adjust the droplet size to meet the dust reduction requirements of dust with different particle sizes.
