Rotating mist stakes of 360 degrees of vertical spray pyrotechnic pyrotechnic pyrotechnic pyrotechnic pyrotechnics of high pressure spray self-rotated smart spray devices, mist pyrotechnics of high pressure long-range spraying of water to the effect of dust abatement, dust suppression, head rotation at 360 degrees, or free angles of spray at a distance of 15 to 50 metres, water vapours after fogging have a good visceral adhesive capacity to pm2. 5, pm10 microdust in air, and collide with mist particles during the fall. The finely fine pm2. 5 particles are wet by water fog and are gradually condensed by their own gravitational effects, and the effects of the dust are evident, with a wide range of effective controls, flexible layout and high practicality. The spray pillar operation equipment is used to spray water from the nozzle mist using high pressure pumps. Fuzzy particles float in the surrounding air, blend with dust particles in the air and fall under self-heaviness, thereby increasing air moisture and reducing multiple effects such as ambient temperature and fallout dust. An intelligent monitoring system that connects dust sensors, load vehicle magnetic field sensors and time control can achieve dust effects under various conditions. Environmental dust-mitigation pillar characteristics 1. The system uses high-pressure hosts, with good fogging, low water use and water conservation. 2. Installation of easy water sources using municipal running water as the medium. 3. Full automated smart kong to reduce usage. 4. The ground is free of water and has no impact on transport. 5. Be able to function 24/7 in high temperature, low temperature and high humidity. 6 to meet the needs of field operations with wind, rain, dust and so forth, and to meet the ip65 protection level. 7/ water spilling operations, such as roads, are no longer required to reduce the costs of operation of haze abatement.
