AI Technical Summary

Technical Problem

Existing technologies struggle to precisely control dust dispersion, especially in high-dust-concentration environments such as mines and cement manufacturing. Traditional dust removal equipment is ineffective in open environments, and a single technology cannot completely solve the problem of dust spillage.

Method used

A two-phase flow spray dust suppression device with an air curtain is adopted. Combining the air curtain device and the two-phase flow spray device, the wind speed and spray pressure are adjusted by the control module to form an airflow barrier and spray atomized droplets to capture dust and inhibit its diffusion.

Benefits of technology

It achieves efficient closed dust diffusion, with a dust capture efficiency of over 95%, reduces water and energy consumption, adapts to different environmental changes, and improves equipment stability and intelligent management.
