The project is located in the water stabilization station of a certain highway renovation and expansion project under the general contracting of Anhui * * * Group, including 7 warehouses including water stabilization material preparation warehouse, water stabilization 1-5 # material warehouse, and mechanism sand processing warehouse. Due to the transportation, loading and unloading of materials and the operation of crushers, there is a significant amount of dust and fly ash, and an automatic sprinkler system needs to be installed to control the dust. The entire system has automatic dust detection, automatic water replenishment, automatic spraying, and remote monitoring functions. The system is composed of main control cabinet, water make-up substation, water make-up pump, water supply tower, spray substation, atomization host, dust concentration sensor, high-pressure atomization pipe network and nozzle. After a long period of practical operation, it has been proven that the system is stable and reliable, and can effectively improve the on-site working environment, playing a good role in environmental protection.
