Among them, construction sites are also the hardest hit areas for urban air pollution, and dust pollution, as the culprit of urban smog, has undoubtedly become a hot spot of concern. According to the record on dust in the "Green Construction Guidelines", the dust control requirements are taken as a mandatory goal. The visual inspection of the structure construction is not more than 1.5m for the foundation construction, and the main construction dust height is 0.5m. Dust control accounts for a large proportion in green construction management, so dust suppression devices are of great significance. The existing dust suppression devices are usually set up independently. During the construction process, the operation is cumbersome, and the professional requirements of the operators are relatively high, so the operation efficiency is low; in addition, the use cost of the existing dust suppression devices is also relatively high. big.

The tower crane sprinkler system uses the tower crane to spray water from a high altitude, which can not only suppress the dust on the construction site, but also prevent fires. The "tower sprinkler system" has obvious effects on reducing dust on the construction site, controlling pollution and reducing haze. It also has an automatic adjustment function. , It can also regularly spray and other functions. The tower crane spray system is installed after the tower crane is completed. Compared with other dust reduction measures, the tower crane spray control system of the construction site environmental protection equipment has the characteristics of full coverage, automation, all-weather, and high dust reduction space.
