▎ 摘　　要

NOVELTY - A self-powered device comprises an ozone gas chamber element and a battery chamber element. The battery chamber element is arranged inside the ozone gas chamber element. The bottom of the ozone chamber cavity is provided with an air inlet, and the top is provided with an air outlet, and the battery cavity is composed of a porous cylinder. The lower portion of the battery cavity is provided with a water inlet (7), the upper portion is provided with a water outlet (8), and the side wall of the porous cylinder is provided with a gas diffusion anode. A metal cathode is arranged inside, and the gas diffusion anode and the metal cathode are connected to the electrical appliance through wires. The electrolyte flows into the battery cavity from bottom to top through the water inlet, flows out from the water outlet, and flows into the water outlet tank. USE - Self-powered device based on metal ozone battery. ADVANTAGE - The device has the characteristics of high electricity production, self-power supply, and synchronous waste gas treatment, and achieves a high level of waste treatment, which has important practical significance for the development of sustainable green water treatment technology. The device achieves the purpose of synchronous ozone quenching, electric energy recovery, and water treatment and purification. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of using the metal-ozone battery-based self-powered device, which involves passing the ozone tail gas in to the ozone gas chamber cavity through the air inlet, contacting the gas diffusion anode in the battery cavity in a spiral shape, and producing a galvanic cell effect with the metal cathode in the battery cavity, promoting the corrosion of the metal cathode, generating current, and promoting the decomposition of ozone electrons into oxygen under the action of electrochemical reduction by the gas diffusion anode, passing the electrolyte from the lower water inlet of the battery cavity to the upper water outlet, corroding metal anode immersed in the electrolyte under the action of electric current to produce hydroxylated metal, reacting with phosphate radicals in wastewater to produce metal phosphate precipitation, and at the same time acting as a flocculant to remove macromolecular organic matter in wastewater, penetrating metal ions having a catalytic reaction with ozone into the electrolyte through the air cathode to promote the conversion of ozone to generate reactive oxygen species. DESCRIPTION OF DRAWING(S) - The drawing shows a structural diagram of a self-powered device based on metal ozone battery. (Drawing includes non-English language text). Water inlet (7) Water outlet (8)
