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.

First claim

What is claimed is:

1. An ultrasound-electrode-nano-porous membrane coupling hydrogen production and sterilization system, comprising a vessel and a plurality of hydrogen production units arranged in the vessel, wherein a 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 wrapping around the broadband ultrasonic generator; a bottom membrane at a bottom of the cavity is hydrophobic at an inner side and hydrophilic at an 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 at an angle of 0-45 degrees from a vertical direction; and a top cover is made of an airtight material.

2. The system according to claim 1 , wherein the bottom membrane is made of nano-scale ceramics, fibers, metal-organic frameworks, or other non-toxic materials.

3. The system according to claim 1 , wherein the broadband ultrasonic generator is adjustable in a range including, without limitation, 20 KHz to 400 KHz, and is located at a center of a reactor to radiate waves to surroundings.

4. The system according to claim 1 , wherein a hydrogen tester is installed at a water outlet of a tank of the system.
