Abstract
The present invention discloses an ultrasound-electrode-nano-porous membrane coupling hydrogen production and sterilization system, which comprises a vessel and a plurality of hydrogen production units arranged in the vessel. The hydrogen production unit comprises a cavity, and a broadband ultrasonic generator and a circular hydrogen production electrode located in the cavity. The circular hydrogen production electrode wraps around the broadband ultrasonic generator. A bottom membrane at the bottom of the cavity is hydrophobic at the inner side and hydrophilic at the outer side, and a side membrane of the cavity is hydrophilic at the inner side and hydrophobic at the outer side and is mounted vertically or obliquely upwards by an angle of 0-45 degrees. The system has the functions of continuously and efficiently facilitating self-circulation micro-flow of a liquid system, hydrogen dissolution (as nano-bubbles), conversion from the interface to the bulk phase and dispersion of bubbles, sterilization and others.
