Innovative Design for Vortex Micro-Nano Bubble generator Based on TRIZ

In order to solve the issues of the micro-nano bubble generation technology, that generally exists high energy consumption and low bubble production, TRIZ method of technical contradiction inventive principles was utilized to provide ideas to design a new-type of micro-nano bubble generating device. The technical contradiction of Sadatomi 's micro-nano bubble generator was described by a pair of general engineering parameters, and the innovative principles were obtained by the technology of contradiction matrix. The concrete implementations of these innovation theories were carried, combing with the actual situation of the micro-nano bubble generation. And a new type of vortex micro-nano bubble generator is developed which shall be more suitable for the bubble generation.
