Sediment nutritive salt lifting device based on air curtain type artificial upwelling

The embodiment of the invention discloses a sediment nutritive salt lifting device based on air curtain type artificial upwelling. The device comprises a foam floating cylinder. A hollow cylinder is installed on the foam floating cylinder, an air injection device is assembled in the hollow cylinder, and the air injection device presses air into one end of an air guide hose; the other end of the air guide hose is fixedly connected with a balance weight, an overlying water air injection nozzle is fixed to the balance weight, a sediment air injection pipe is fixed to the lower end of the balanceweight, and the other end of the air guide hose is communicated with the overlying water air injection nozzle and the sediment air injection pipe. The device is expected to be applied to large-scale engineering in sea areas which are lack of nutritive salt at home and abroad or have large demand on algae and can enhance ocean carbon sink and improve water quality. 本发明实施例公开了一种基于气幕式人工上升流的沉积物营养盐提升装置，包括：泡沫浮筒；所述泡沫浮筒上安装有空心筒，所述空
