First, the construction of a spray device, install a multi-layer high-pressure nozzle, forming a water curtain to block the smoke. Second, the water pipes, sprinkler pipe network, water cannons, sprinklers, etc., for loading and unloading areas, storage areas, roads and coal yard entrance road to wash. Third, an additional washing tank, reduce coal dust contaminated with road vehicles, and transportation units proposed strict requirements before they leave the non-overload and excessive load after tarpaulin cover. Fourth, there is a person responsible for spraying, washing, dredging, dredging canals and environmental protection. Fifth, the dust loading and unloading tankers pull operation using a closed factory pull material transport vehicles will be covered with a tarpaulin. Six, and will regularly take control means curing coagulant or sprinkler spray dust suppression, etc., enhance the timely cleaning of the road, reducing dust transport vehicles. Seven steps to set up wind and dust, dust walls establish Wind Dust Network composition. Eight, establish green belts and residential areas. Nine, the smoke big business, moved quite far away from residential areas with good ventilation. Ten, for device improvement, try to shut down polluting enterprises. Water washing yard wind Dust wall design recommendations: 1, wind and dust walls: HS-F3-type air filter, thickness 0.7mm or 0.8mm, single mesh width 810mm and 910mm two kinds; single length 4m- 6m; 2, steel: pipe 2 inches, 3 inches, welding points require full welding, spacing requirements 3.5m-6m; 3, Foundation: Concrete supplier Model C30; 4, the design height: This program supports 4m - 6m.
