As urban construction booms, dust pollution from construction sites has become increasingly severe, with the concentration of PM2.5 in the air continuously rising. Respirable particles have always been the primary pollutants in urban air, and the respirable particles caused by dust account for over 40% of the total. The impact on residents' production and living is becoming more significant. Minshun Environmental Protection's tower crane spray dust removal system utilizes green, environmentally friendly, and energy-saving new technology. It taps into the on-site rainfall well or fire hydrant reservoir as a water source, boosts the pressure, and then distributes water through the tower crane's supply pipes to the spray heads on the boom for high-altitude spraying. Tests show that under wind speeds below level 2, the high-altitude spraying can reduce the concentration of particles in the site air by 84%, achieving a particularly significant dust reduction effect. Additionally, the adjustable spray mist provides maintenance for concrete structures, saving labor costs and enhancing the quality of construction work.

Tower Crane Spraying Equipment Performance

1. The spray range is extensive, fully covering the area within the crane's rotating radius.

2. Suppress dust at construction sites, control pollution and reduce haze, and prevent and decrease fires.

3. Cool the ground during hot weather and perform fog curing on concrete.

Tower Crane Spraying Equipment Composition

1. The tower crane dust suppression system includes: crane rotating universal joint, support frame, water pipes, filters, tees, flexible joints, adjustable nozzles, etc.; PPR pipes, PE pipes, or galvanized steel pipes should be used as the main lines.

2. Tower Crane High-Altitude Sprinkler System Water Extraction: Can be connected to the municipal water network for water supply, or combined with a recirculating water recovery system, and then pumped into the tower crane sprinkler system by a pressure pump.

Tower Crane Spraying Equipment Composition:

The sprinkler system includes pipes, pipe swivel joints, spray nozzles, pressure pumps, timers, etc., with spray nozzles ideally placed every 2-4 meters. The tower crane high-altitude sprinkler system can be used for dust suppression and temperature reduction within the rotation radius of the tower crane, fire prevention and disaster reduction, and concrete curing. The tower crane high-altitude sprinkler system can be connected to the municipal water network for water supply and can be combined with a recirculating water recovery system. The recirculating water recovery system mainly consists of water collection, filtration, sedimentation, storage facilities, pressure pumps, and recycling.

The tower crane sprinkler system takes advantage of the high-altitude operation of tower cranes. It pressurizes water and delivers it through supply pipes in the crane's frame to the sprinkler heads on the boom for high-altitude spraying. In addition to effectively reducing dust, it also cools down the construction site and can assist in fire suppression. Calculations show that high-altitude sprinkling can reduce the concentration of particulates in the worksite atmosphere by 84%. Following the Environmental Protection Bureau's directives and the development of air pollution, the tower crane high-altitude sprinkler dust reduction system, with its surround-spraying feature, will be widely used and promoted across construction sites nationwide.
