The invention discloses a small micro-bubble generator and a method, and belongs to the field of micro-bubble drag reduction. The generator comprises a water pump, three valves, a controller, a bubblegeneration chamber, a first pipeline, a second pipeline and a one-way valve. The water pump, a first valve, the bubble generation chamber and a second valve are sequentially mounted on the first pipeline; a solid reaction raw material block is mounted in the first pipeline through a filter screen box to form the bubble generation chamber; a first port and a second port of a second pipeline are connected with two ends of the bubble generation chamber and are positioned between the first valve and the second valve; and a third port of the second pipeline is connected with the outlet end of thefirst pipeline, and a third valve and the one-way valve are installed between the second port and the third port. According to the device, a carbon dioxide gas is generated through reaction of mixed solids of water, an organic acid and sodium bicarbonate, generated bubbles are small, density is large, drag reduction is better facilitated, distribution in water flow is uniform, an extra gas sourcedoes not need to be carried, and the device is small in size and low in cost.

    本发明一种小型微气泡发生器及方法,属于微气泡减阻领域;包括水泵、三个阀门、控制器、气泡发生室、第一管道、第二管道、单向阀;第一管道上依次安装有水泵、第一阀门、气泡发生室、第二阀门;固态反应原料块通过滤网盒安装于第一管道内形成气泡发生室;所述第二管道的第一端口和第二端口分别与所述气泡发生室的两端连通,并位于所述第一阀门和第二阀门之间;第二管道的第三端口与第一管道的出口端连通,第三阀门和单向阀安装于第二端口和第三端口之间。装置通过水和有机酸与碳酸氢钠混合固体反应生成二氧化碳气体,生成的气泡小,密度大,更有利于减阻,在水流中分布均匀且不需要携带额外的气源,装置体积小,成本低。
