High-Pressure Spray Dust Suppression System Overview of Fog Cannon Machine:

1.Dust Concentration Reduction:Before upgrading the fog cannon's spray dust suppression system, individual dust concentration analysis showed levels between 6.09 to 6.44 mg/m³ (respirable dust concentration). Post-upgrade, the analysis indicated a significant reduction to 3.25 to 3.65 mg/m³. This improvement underscores the machine's effectiveness in enhancing air quality and reducing respirable dust exposure for workers.

2.Spray Pump Performance:The fog cannon's spray dust suppression pump achieves a water outlet pressure of up to 6.3 MPa, ensuring ample water flow for effective dust suppression around coal shearers. This high-pressure capability allows it to reach dust-prone areas both inside and outside the shearer, maintaining a clean and safe operational environment without compromising on water usage efficiency or safety standards.

3.Integrated Dust Control Mechanism:Through a specialized proportioning box, the fog cannon mixes dust-proof water with suppressants, enhancing filtration and distribution. The resulting air curtain, formed by the coal shearer spray, acts as a barrier that controls the spread of dust from the source. This strategic containment prevents dust from dispersing throughout the workspace, thereby improving overall working conditions and reducing the impact on personnel health and equipment performance.

4.Operational Benefits:The upgraded system not only mitigates dust emissions but also enhances operational efficiency by minimizing downtime due to dust-related issues. By maintaining a stable and controlled environment, the fog cannon contributes to prolonged equipment lifespan and reduced maintenance costs, ensuring sustainable and productive mining operations.

The high-pressure spray dust suppression system of the fog cannon machine exemplifies a robust solution for mitigating dust emissions in industrial settings, particularly around coal shearers. By significantly reducing respirable dust concentrations and effectively controlling dust dispersion with its advanced pump and integrated dust control mechanism, the fog cannon enhances both environmental safety and operational efficiency. Its ability to create a protective air curtain around work areas not only safeguards worker health but also ensures uninterrupted mining operations. Embracing such innovative dust suppression technologies underscores a commitment to sustainable and responsible industrial practices, paving the way for cleaner, safer, and more productive work environments.
