An upwelling device comprises a floating platform, a runner pipe, an air compressor and an air injection nozzle, the top surface of the floating platform is higher than the sea surface, the floating platform is provided with a mixing cavity, the top surface of the floating platform is provided with a top hole penetrating through the mixing cavity, the bottom surface of the floating platform is provided with a bottom hole penetrating to a mixing pool, and the side surface of the floating platform is provided with a communicating hole penetrating to the mixing cavity. The circulating pipe is vertically arranged on the bottom surface of the floating platform, a pipe hole of the circulating pipe corresponds to the bottom hole, the pipe hole of the circulating pipe is communicated with seawater on the bottom layer, the air compressor is arranged above the floating platform, the air injection nozzle is arranged in the pipe hole of the circulating pipe, and the air compressor is connected to the air injection nozzle; according to the invention, waves on the sea surface enable seawater on the top layer to turn over the floating platform and enter the top hole so as to enter the mixing cavity, eutrophic saline water with the density smaller than that of seawater on the bottom layer is formed, the eutrophic saline water flows out to the top layer of the seawater through the communicating hole, and the eutrophic saline water is relatively low in density and settling velocity and can stay in a euphotic layer for a relatively long time; and the utilization efficiency of the phytoplankton is high.

    一种上升流装置,包括浮台、流通管、空压机和注气喷头,浮台的顶面高于海面,浮台设有混合腔,浮台的顶面设有贯穿于混合腔的顶孔,浮台的底面设有贯穿至混合池的底孔,浮台的侧面设有贯穿至混合腔的连通孔,流通管竖直设置于浮台的底面,流通管的管孔和底孔相对应,流通管的管孔连通于底层的海水,空压机设于浮台的上方,注气喷头设于流通管的管孔内,空压机连接于注气喷头;本发明中,海面的波浪使顶层的海水翻过浮台打入顶孔从而进入混合腔,形成密度比底层海水小的富营养盐水,该富营养盐水通过连通孔向海水的顶层流出,该富营养盐水的密度较小,沉降速度较慢,可以在真光层停留较长的时间,浮游植物的利用效率较高。
