With the rapid development of urban construction, the problem of construction dust is becoming increasingly severe, and the concentration of PM2.5 in the air is continuously rising due to construction dust. Inhalable particles have always been the primary air pollutant in cities, with the proportion of inhalable particles caused by dust exceeding 40% of the total. The impact on residents' production and living is becoming more and more serious. Minshun Environmental Protection's tower crane spray dust suppression system utilizes green, environmentally friendly, and energy-saving new technology. It takes advantage of the characteristics of high-altitude operations of tower crane spray, using the construction site's water well or fire pond as the water source. After being pressurized, the water is transported through the water supply pipes in the tower crane frame to the spray nozzles on the boom for high-altitude spraying. Tests show that under wind speeds below level 2, high-altitude spraying can reduce the concentration of particles in the air on the construction site by 84%, achieving particularly significant dust suppression effects. Additionally, the system provides care for concrete structures through adjustable spray mist, saving labor costs for maintenance and improving the quality of construction work.

Tower Crane Sprinkler System Overview

The tower crane spray system is used for dust suppression and cooling within the rotation radius of the tower crane, as well as fire prevention and disaster reduction.

2. The tower crane sprinkler system can be connected to the municipal water network for water supply, and can also be integrated with a circulating water recycling system. The circulating water recycling system mainly consists of circulating water collection, filtration and sedimentation, storage facilities (tanks), pressure pumps, and recycling processes.

3. Tower Crane Sprinkler System Components: Tower crane timing distribution box, high-pressure water pump, tower crane swivel joint, galvanized steel pipe or PPR pipe, transition, tee, rotating nozzle, ball valve, etc.

4. The spacing of pumps, tees, risers, nozzles, etc., is determined by the nozzle type and coverage radius, and their layout must meet the on-site requirements.

5. Due to the strict prohibition of welding on tower crane standard parts, two fixed supports are set on the universal joint for installation. They are connected and secured to the universal joint with screw clips. The pipe support is connected to the tower crane standard parts using screw clips.

6. Regularly inspect the pipeline support system and ensure that the universal joints are aligned with the tower crane's universal wheel shaft core, checking for any misalignment or movement.

Features of the tower crane sprinkler:

The tower crane high-altitude misting dust control system can accept data collected by a PM10 dust monitor and can automatically turn on or off the dust control system. It also allows remote operation to control the system's start and stop, as well as the size of the mist and water volume, enabling three functions: operation control for the tower crane driver, ground concrete wet curing, and construction site fire prevention.

2. The tower crane high-altitude sprinkling dust suppression system features three functions: dust control on construction sites, wet curing of concrete, and fire protection on construction sites.

3. The tower crane high-altitude misting dust suppression system, utilizing the tower crane's 360-degree rotation, can cover the construction site. It provides a three-dimensional misting from the air to the ground, thereby inhibiting the drifting and spreading of airborne dust.

4. In case of fire on construction sites, the system can be immediately switched to fire mode, increasing the water spray volume, allowing for timely high-altitude extinguishing of flames and rapid control of the fire.
