Dust pollution in the atmosphere is an important factor for causing the reduction of urban atmosphere acid rain, photochemical smog and air visibility, and seriously endangers human health. Along with the increase of the large bulk cargo transportation and storage quantity year by year, the dry bulk cargo, especially various dust-raising heavy cargo species such as cement clinker, tapioca, ore sand, coal, iron ore powder and the like, are loaded and unloaded to the surrounding area of the port to cause dust pollution.
The dust pollution of the dry bulk cargo loading and unloading mainly comes from the processes of storing, transferring and loading and unloading bulk cargo, wherein the dust pollution of storage yards such as port coal, mineral powder and the like greatly exceeds the national secondary air quality standard. Particularly, in the loading and unloading process of coal, mineral powder and the like, because of the higher fall during the discharging of the grab bucket, the transfer point becomes another dust source in the loading and unloading process of the coal and the mineral powder, and the average dust concentration range of the work space of the transfer point is 57.5-285 mg/m < 3 >, which is seriously beyond the national standard of 10mg/m < 3 >. For dust pollution caused by grab operation, no relevant detection data are found, but in the order of magnitude, the dust concentration at the transfer point of the belt conveyor is not lower.
The common negative pressure loading equipment suitable for loading and unloading dry bulk cargos adopts a fixed working mode, and during the working period of the unloading portal crane, the negative pressure fan continuously works, and as the unloading portal crane is intermittent working equipment, the negative pressure fan of the loading equipment continuously works in the idle time between two unloading processes, so that the power consumption is larger.
