Suspended solid purifying device suitable for dredging engineering in South China Sea

Abstract

The invention provides a suspended solid purifying device suitable for dredging engineering in South China Sea. The device comprises an upper filtering empty container, a lower sand collecting tunnel and bottom stretchable brackets. A wind power generation structure is utilized to supply energy to the whole device, sand filtering screens are utilized to directly filter sand, the capacitance formed by the adjacent sand filtering screens is utilized to absorb heavy metal, and meanwhile, the lengths and angles of the brackets can be adjusted according to the real topography at the seabed in the dredging area in South China Sea. The device utilizes the filtering empty container and the lower sand collecting tunnel to centrally filter the silt and heavy metal mixed suspended solids, the aquatic plants at the seabed can be prevented from being covered by the mixed suspended solids and the influences of the silt and heavy metal mixed suspended solids on the living environment of benthos can be reduced so that the influence of the dredging engineering on the marine ecological environment can be reduced. The harmonious coexistence of human and nature can be realized and the purpose of protecting marine ecosystem can be achieved.

Description

technical field [0001] The invention relates to the field of sediment filtration, in particular to a suspended matter purification device suitable for dredging projects in the South China Sea. [0002] technical background [0003] With the rapid development of economic globalization and world trade, in order to meet the needs of large-scale development of container and tanker transportation, countries have built a large number of ports, widened and deepened waterways to increase shipping capacity, and marine infrastructure projects have developed rapidly. The South China Sea is an important part of my country's maritime power strategy, and its infrastructure construction represented by dredging projects is in full swing. [0004] In the South China Sea dredging project, due to the continuous agitation of the underwater soil by the dredger dredging equipment, such as the cutter head and the grab bucket, the bottom mud is suspended; Dredging boats dredging soil dumped suspend...

Problems solved by technology

[0005] In addition, because the South China Sea is located in the convergence zone of the three major plates of the Indian Ocean, the Pacific Ocean, and the Eurasian continent, the geological structure and terrain fluctuations of the South China Sea seabed are extremely complex, and it is difficult for general machinery to maintain a continuous and stable operation on the seabed; and the South China Sea is far away from the land. Facility layout is difficult and costly
