Vehicle-mounted fog cannon machines and spraying dust trucks are different devices for reducing airborne dust, varying in design, working principles, and application scenarios, as detailed below:

Design Structure

Vehicle-mounted fog cannon machine: Composed of an impeller, air duct, rear flow deflector, spraying device, and 支架 (support frame), it generates fine water droplets and delivers them over long distances for dust control.

Spraying dust truck: Equipped with a motor, high-pressure fan, horizontal rotation mechanism, elevation control device, guide cylinder, atomizing nozzles, high-pressure pump, and water tank, it sprays ultra-fine water mist to trap airborne particles.

Working Principles

Vehicle-mounted fog cannon machine: Uses an imported high-pressure pump and fine nozzles to atomize water, which is then carried by fan airflow over long distances. Micron-level water droplets bond with dust, causing it to settle.

Spraying dust truck: Converts water from the tank into fine mist via a motor and high-pressure pump, which is ejected by a high-pressure fan to adsorb and sink dust particles.

Application Scenarios

Vehicle-mounted fog cannon machine: Suitable for open spaces like coal mines, material handling areas, waste treatment sites, construction/demolition sites, warehouses, and ports, as well as urban PM10/PM2.5 control.

Spraying dust truck: Mainly used in urban sanitation for road flushing, green belt irrigation, and construction site dust control.

Functional Features

Vehicle-mounted fog cannon machine: Features fast dust removal, uniform spraying, frequency conversion startup, PLC control, hydraulic rotation, optimized air duct design, stable performance, low noise, and energy efficiency.

Spraying dust truck: Emits ultra-fine mist to decompose air pollutants, with multi-functions including dust suppression, spraying, pesticide application, and guardrail washing.

Operational Convenience

Vehicle-mounted fog cannon machine: Drivers can operate it anywhere via advanced electric controls, independent of geographic limitations.

Spraying dust truck: Typically requires an operation platform for control, involving relatively complex procedures.

Recommendations

Scenario suitability: Choose based on environment (e.g., open areas for fog cannon machines, urban roads for dust trucks).

Performance parameters: Consider atomization effect, spraying range, and coverage.

Maintenance costs: Evaluate long-term economic viability.

Environmental compliance: Ensure alignment with current standards.

Safety: Prioritize operator and site safety.

In summary, while both devices aim to control dust, their design, application, functions, and operation differ. Select according to specific needs and usage environments.
