Fluid power generation method and device based on funnel-shaped nano channel film

Abstract

The invention provides a fluid power generation device based on a funnel-shaped nano channel film. A funnel-shaped nano channel comprises a neck part and a conical part. The diameter of the neck opening end is relatively small, so that the possibility of electric charge separation when a working fluid flows through double charge layers near the inner surface of the channel is enhanced, the ion selectivity is improved, and higher and more stable dynamic current can be generated; the diameter of the opening end of the conical part is large, and the conical nano channel can reduce the influence of the channel on the flux of the film, so that flowing current is improved, and the stability of the flowing current is improved; therefore, the two ends of the funnel-shaped nano channel can facilitate selective ion passing; and bidirectional currents which change in directions alternately and basically equal in sizes can be obtained when the fluid is intermittently changed in the direction of passing the funnel-shaped nano channel.

Description

technical field [0001] The invention relates to the technical field of utilizing power generation. More specifically, it relates to a method and device for generating electricity based on a funnel-shaped nanoporous membrane fluid. Background technique [0002] The development and utilization of energy is the guarantee of human survival and sustainable social development. The reserves of traditional non-renewable energy are gradually declining in the process of gradual exploitation. At the same time, their wide application has also brought about practical problems such as energy security, environmental pollution, and climate change that affect human survival and development. The global traditional energy structure needs to be transformed into a clean and low-carbon energy structure. Energy-based structure. Among them, the renewable energy contained in the water system is also extremely abundant and ubiquitous, such as the mechanical energy of the water flowing process and t...

Problems solved by technology

The ion selectivity and flux of the membrane are important factors affecting fluid power generation. In theory, there is a trade-off between the ion selectivity and flux of the membrane. High ion selectivity cannot pass through a large amount of fluid. Therefore, it produces a lower energy density

The current state-of-the-art nanofluidic structures are limited to symmetrical channel devices, which have the advantages of simple process, but the disadvantages of poor stability and high energy consumption severely limit the practical use of this process.
